The remote control operation unit 30 has an operation panel 31 on the surface thereof, and has an operation button 32 which is an operation switch. The operation buttons 32 form a number necessary for operating the agricultural work machine attached to the tractor. The remote controller operation unit 30 has a transmission unit that wirelessly transmits a signal operated by the operation button 32. Further, if necessary, a wireless reception function can be added to serve as a transmission / reception unit. The side surface of the remote control operation unit 30 has a gradient portion 33 in which a gradient is formed in a direction in which the area decreases toward the surface. This can be formed by utilizing, for example, the draft of the resin.

On the other hand, a battery storage unit 35 is provided on the back surface of the remote control operation unit 30, and the battery 201 is stored in the recess in shape. The battery 201 can store a required number of batteries. Further, the inner surface of the battery housing portion 35 has a plurality of contacts 35a in contact with the positive electrode terminal and the negative electrode terminal of each battery 201. In FIG. 1, three batteries 201 are housed side by side in the vertical direction, and contacts 35a are provided on the upper and lower inner surfaces. Further, the battery storage unit 35 is installed on the back surface of the remote controller operation unit 30 below the center.

Further, a cover 36 can be attached near the outside (back side) of the battery storage portion 35, and the cover portion 36a can cover the battery storage portion 35 in which the battery 201 is stored. A packing 37 can be attached between the cover 36 and the battery storage portion 35 along the periphery.

Further, by fixing with the fixing screw 38, the cover 36 can be firmly fixed to the remote control operation unit 30. In FIG. 1, the fixing portion 36b is arranged on the lower side of the cover 36. Further, when the cover 36 is attached, the back surface of the remote control operation unit 30 is in a substantially flat state.

With these configurations, the power supply of the remote controller operation unit 30 can be supplied by the battery 201.

FIG. 2 shows an embodiment when a power supply connection component is attached to the remote control operation device for an agricultural work machine of the present invention, (a) is a side view of the power supply connection component before connection, and (b) is a power supply connection component. The side view of the connected state, (c) is the rear view of the state in which the power supply connection component is connected.

When the battery 201 runs out in the state of FIG. 1, the operator removes the cover 36 from the remote control operation unit 30, takes out the battery 201, and instead connects the power supply connection component 40 to the tractor. Enables power supply. As a result, the operation by the remote controller operation unit 30 can be continued.

The power supply connection component 40 has a battery storage side connection portion 41, a cover portion 42, a harness portion 43, a power supply connector 44, wiring 45, and an external connector 46. The battery storage side connection portion 41 and the cover portion 42 form the main body portion 49 of the power supply connection component 40.

The battery storage side connection portion 41 is a portion to be inserted and arranged in the battery storage portion 35, and has a contact 41a on the side surface that comes into contact with the contact 35a of the battery storage portion 35. The contact 41a is provided at a position where it comes into contact with the contact 35a necessary for supplying electric power. Therefore, there are at least a plurality of contacts 41a, and for example, when the batteries 201 are connected in series, the positions where the two contacts 41a are end to end in series (if there are three batteries, the left and right and the top and bottom are It suffices to prepare for a symmetrical position).

The cover portion 42 is formed integrally with the battery storage side connection portion 41 and is formed wider than the battery storage side connection portion 41, and replaces the cover 36 with the battery storage portion 35 connected to the battery storage side connection portion 41. It covers the whole area. Therefore, the battery storage side connection portion 41 to the cover portion 42 has an outward step portion 42a. By mounting the packing 80 on the step portion 42a, the packing 80 is interposed between the cover portion 42 and the remote control operation portion 30 along the periphery of the cover portion 42 on the battery storage portion 35 side. As a result, the waterproof and dustproof functions can be exhibited. Further, a converter 48, which will be described later, is built in the main body 49. The cover portion 42 has a certain thickness as needed.

The fixing portion 47 is formed so as to extend on the same surface as the cover portion 42, and by fixing with the fixing screw 38 in the same manner as the cover 36, the cover portion 42 covers the battery housing portion 35 and the main body portion 49 is remote controlled. It can be firmly fixed to the operation unit 30 via the packing 80.

The harness portion 43 is a harness having wiring for electrically connecting the main body portion 49 and the power connector 44. The connection portion 43a of the harness portion 43 is connected to the cover portion 42, and the connection portion 43a projects outward (back side) so as not to interfere with the remote control operation portion 30 (so that the cover portion 42 can be covered). ..

When the main body 49 is attached to the remote control operation unit 30, the back surface of the remote control operation unit 30 is in a flat state as in the case where the cover 36 is connected. The connection portion 43a of the harness portion 43 projects outward (back side), from which the harness portion 43 extends downward.

The power connector 44 is a connector that can be connected to the connection portion from the power supply of the tractor. For example, it is possible to connect to the power supply connection unit 12a as an external power source connected from the battery 11 included in the tractor 1 described later in FIG. At this time, if the connecting portion 12a of the tractor 1 complies with the Nichino Kogyo standard, the power supply connector 44 may have a connector shape specified by the Nichino Kogyo standard.

The wiring 45 is a wiring branched from the power connector 44 separately from the wiring of the harness portion 43, and is connected to the external connector 46.

The external connector 46 is a connector for connecting to another output device. By making the shape of the power supply connection portion 12a from the power supply of the tractor 1 the same, it is possible to connect to the connector of the output device that can be connected to the power supply connection portion 12a.

FIG. 3 is a schematic view showing a circuit state of a power supply connection component in the first embodiment of the remote control operation device for agricultural work machines of the present invention. The battery 11 of the tractor 1 is connected to the converter 48 in the main body 49 via the external power harness 12 and the harness portion 43 connected to the external power harness 12. The converter 48 converts the voltage A on the battery 11 side into a voltage B matched to the remote control operation unit 30. Then, it is connected to the remote controller operation unit 30 via the contact 41a of the battery storage side connection 41 and the contact 35a of the battery storage 35. For example, 12V, which is the voltage A of the battery 11, is converted to 4.5V, which is the voltage B of the remote control operation unit 30. The voltage B of 4.5 V is an example assuming a case where three dry batteries are connected in series.

FIG. 4 is a schematic plan view showing an example of the arrangement of the tractor and the agricultural work machine to which the remote control operation device for the agricultural work machine of the present invention is applied. The present invention can be applied to an agricultural work machine 2 that is attached to a tractor 1 to perform agricultural work. The tractor 1 has a battery 11, and the agricultural work machine 2 has a wireless transmission / reception unit 21, a control unit 22, and an actuator 23. The battery 11 can be used as a power source for the tractor 1.

An external power harness 12 is connected to the battery 11, and the tip thereof serves as a power connection portion 12a via a switch 12b. The power supply connection unit 12a can connect the power supply to an external device. The switch 12b can be shared with the engine start switch of the tractor 1, and can be configured as a key switch that is turned on when the key for starting the engine is rotated, for example. As a result, wasteful power consumption can be prevented when the work by the tractor 1 is not performed. The shape of the power supply connection portion 12a can be, for example, a connector shape defined by the Nichino Kogyo standard.

When the battery 201 is used as the power source for the remote control operation unit 30, the power supply connection unit 12a of the external power supply harness 12 is directly connected to the connector 25a of the work machine side harness 25 without using the power supply connection component 40. To. Therefore, the battery 11 can be used as a power source to operate the devices on the farm work machine 2 side such as the wireless transmission / reception unit 21, the control unit 22, and the actuator 23.

On the other hand, when the battery 201 is not used as the power source for the remote control operation unit 30, the power connection component 40 is connected to the remote control operation unit 30. Then, the power supply connection portion 12a of the external power harness 12 is connected to the power connector 44 of the power supply connection component 40. On the other hand, the external connector 46 of the power supply connection component 40 is connected to the connector 25a of the work machine side harness 25. Therefore, using the battery 11 as a power source, the remote controller operation unit 30, the wireless transmission / reception unit 21, the control unit 22, the actuator 23, and other devices on the farm work machine 2 side can be operated.

When the operator operates the remote control operation unit 30, the operation signal from the remote control operation unit 30 is sent to the wireless transmission / reception unit 21, and the control unit 22 operates the actuator 23. A specific example of the actuator 23 will be described later. Further, if necessary, it may be possible to transmit the information from the control unit 22 from the wireless transmission / reception unit 21 to the remote control operation unit 30.

FIG. 5 is a rear view showing an example of an agricultural work machine to which the remote control operation device for agricultural work machines of the present invention is applied. FIG. 6 is a front view showing an example of an agricultural work machine to which the remote control operation device for agricultural work machines of the present invention is applied. The agricultural work machine 2 of FIGS. 5 and 6 is a substitute scraping work machine 50 provided with a folding mechanism. The input shaft 51 side is attached to the tractor 1, and the power from the tractor 1 is input via the input shaft 51 to cover the tractor 1. The scavenging work is performed by rotating the scavenging claws inside the 52 and the first ground leveling body 53. An example of the actuator 23 will be described using the puddling work machine 50.

As the cylinder expands and contracts, the electro-hydraulic cylinder 56 can act on the rotating mechanism 57 to fold the side working portion 55 inward (as shown on the left side of FIG. 6) and shorten the overall width of the puddling machine 50. .. The extension leveling body driving device 60 rotates the extension leveling body 61 around the rotation shaft 61a via the arm 62 and the wire 63 by rotating the internal motor, and extends the extension leveling body 61 to the outside. You can choose to fold it inward or fold it inward. The second ground leveling body driving device 66 rotates the second ground leveling body 65 via the second ground leveling body link means 67 by rotating the internal motor, and puts it in a soil-pulling state fixed on the lower side. It is possible to select whether to use the normal scratching state in which the rotation is not fixed.

The electro-hydraulic cylinder 56, the extension leveling body drive device 60 (motor), and the second leveling body drive device 66 (motor) can be operated by operating the remote control operation unit 30 as the actuator 23.

The example of the actuator 23 is not limited to the puddling work machine, and can be widely applied to any actuator used in a farm work machine that is attached to a tractor to perform farm work.

7A and 7B show an embodiment of a holder for holding a remote control operation device for an agricultural work machine of the present invention, in which FIG. 7A is a front view and FIG. 7B is a side view. 8A and 8B show an embodiment in which a remote controller operating device for an agricultural work machine is attached to the holder of FIG. 7, where FIG. 8A is a front view and FIG. 8B is a side view.

The holder 100 is composed of a plate-shaped back surface portion 110 and side surface portions (151, 152, 153, 154, 155) formed around the back surface portion 110 toward the front side as a whole. The holder 100 can be formed of, for example, resin.

From the back surface portion 110, a plurality of convex portions 120 are formed on the side to which the remote control operation unit 30 is attached. The convex portions 120 are formed in a shape and number necessary to support the back surface of the remote control operation unit 30, and in the example of the figure, the first convex portion 121, the second convex portion 122, and the third convex portion are formed from the upper side. 123 and three convex portions are formed. At this time, the lowermost third convex portion 123 is formed so as not to interfere with the harness portion 43 including the connecting portion 43a.

The holder 100 has a mounting hole 140, and in the example shown in the figure, the holder 100 has a back extension portion 111 on the upper side of the back surface portion 110, and the back surface extension portion 111 has a first mounting hole 141. Further, a second mounting hole 142 is provided in the back surface 110 between the first convex portion 121 and the second convex portion 122, and a third mounting hole 142 is provided in the back surface portion 110 between the second convex portion 122 and the third convex portion 123. It has holes 143. The holder 100 can be installed in a suitable place of the tractor 1 such as near the driver's seat. The installation can be performed by using a plurality of mounting holes 140, and a method such as hooking the first mounting hole 141 on a hook is also conceivable. Further, it may be attached to the back surface 110 with a magnet or double-sided tape.

The notch 130 formed in the holder 100 is a hole for discharging the soil adhering to the remote control operation unit 30 when it collects in the holder 100. It is possible to prevent the remote control operation unit 30 from being unable to be removed or water from accumulating in the holder due to the soil accumulated inside. A plurality of notch portions 130 may be installed on the lateral side so that soil and water can be easily discharged. In the example of the figure, it is formed on both sides between the back surface portion 110 and the side surface portion, and the first notch portion 131, the second notch portion 132, and the third notch portion 133 are formed on both sides from the upper side. .. The third notch 133 at the bottom can be enlarged to facilitate the discharge of accumulated soil.

The side surface portion is provided to hold the side surface of the remote control operation unit 30. In the example of the figure, the side surface portion is formed of an upper side surface portion 151, an upper lateral side surface portion 152, an inclined portion 153, a lower lateral side surface portion 154, and a lower side surface portion 155, and when the remote control operation unit 30 is attached, the side surface portion is formed. It has a shape along the periphery of the remote control operation unit 30. Further, the plurality of protrusions 160 provided on the side surface portion can hold the remote control operation unit 30 so as not to fall from the holder 100 to the front side. In the example of the figure, the upper side surface portion 151 has a first protrusion 161 provided inward, and the lower lateral side surface portion 154 has a second protrusion 162 provided inward.

The upper side surface portion 151 is a side surface formed on the upper surface side of the remote control operation unit 30, and the first protrusion 161 is formed, and has a constant height required for this purpose.

The upper lateral side surface portion 152 is a side surface formed on the upper lateral side of the remote control operation unit 30, and is formed to have a low height so that the remote control operation unit 30 can be easily taken out. Specifically, it is formed at a height to a position lower than half the thickness of the remote control operation unit 30.

The lower lateral side surface portion 154 is a side surface formed on the lower lateral side of the remote control operation unit 30, and each of the second protrusions 162 is formed and has a constant height required for this purpose. An inclined portion 153 is formed between the upper lateral side surface portion 152 and the lower lateral side surface portion 154.

The lower side surface portion 155 is a side surface formed on the lower surface side of the remote control operation unit 30 and is formed at the same height as the lower side surface portion 154 so that the remote control operation unit 30 does not shift downward. Further, the lower side surface portion 155 is formed with a groove 170 which is a notch portion opened to the front surface side, whereby the harness portion 43 can pass to the outside.

In the state of FIG. 8, the back surface portion 110 is located on the back surface of the remote control operation unit 30, and the side surface portion is located on the side surface of the remote control operation unit 30. Then, the back side of the remote control operation unit 30 comes into contact with the convex portion 120 of the back surface portion 110, and the front surface side of the remote control operation unit 30 is caught and held by the protrusion 160. The holding by the protrusion 160 is stopped by hooking the first protrusion 161 in the middle of the slope portion 33 on the upper side of the remote control operation unit 30. Further, the second protrusion 162 is hooked and stopped in the middle of the slope portion 33 on the lower lateral side surface of the remote control operation unit 30.

When the operator takes out the remote control operation unit 30 from the holder 100 from the state of FIG. 8, he grabs the remote control operation unit 30 near the lower upper lateral side surface portion 152 and pulls it out from the holder 100 toward the surface side. At this time, the first protrusion 161 and the second protrusion 162 are pushed along the slope portion 33 and slightly deformed by the elasticity of the upper side surface portion 151 and the lower lateral side surface portion 154, so that the first protrusion 161 and the second protrusion 161 and the second protrusion 162 are slightly deformed. The remote control operation unit 30 can be pulled out over the protrusion 162. At the same time, the harness portion 43 is taken out from the groove 170 open on the surface side. Further, when the remote control operation unit 30 is attached to the holder 100, it can be attached over the first protrusion 161 and the second protrusion 162 due to the elasticity of the upper side surface portion 151 and the lower side surface portion 154. By pulling out the remote control operation unit 30 from the holder 100 to the surface side in this way, the operator can quickly take out the remote control operation unit 30 according to the situation and operate it at hand or the like. At this time, since a part of the side surface portion is vacant, the remote control operation unit 30 can be easily grasped and taken out.

FIG. 8 describes the case where the power supply connection component 40 is connected to the remote control operation unit 30 for the installation in the holder 100, but the case where the power supply connection component 40 is not connected to the remote control operation unit 30 (battery 201). The remote control operation unit 30 can be held by the holder 100 even when the remote control operation unit 30 is attached. As can be seen from FIG. 8, the remote control operation unit 30 can be attached to the holder 100 even in a configuration in which the harness unit 43 and the connection unit 43a do not exist.

FIG. 9 is a schematic view showing a circuit state of a power supply connection component in the second embodiment of the remote control operation device for agricultural work machines of the present invention. In the second embodiment, the capacitor 85 is added to the power supply connection component 40, and the other parts are the same as those in the first embodiment.

The capacitor 85 is connected in parallel with the converter 48, and is connected to a circuit on the remote control operation unit 30 side (opposite side of the battery 11) of the converter 48. The capacitor 85 is arranged in the main body 49 of the power supply connection component 40, and can store a certain amount of electrical energy.

By having the capacitor 85, when the power supply connecting component 40 is connected to the power source (battery 11), the capacitor 85 is charged. Then, in a state where the power supply connection component 40 is not connected to the power supply, the remote controller operation unit 30 can be used for a certain period of time using the capacitor 85 as the power supply.

For example, when the operator wants to use the remote control operation unit 30 away from the driver's seat of the tractor 1, he / she cannot move beyond the length of the harness unit 43. At this time, even if the power supply connection component 40 is removed from the power supply connection portion 12a of the external power harness 12, the remote control operation unit 30 can be used for a certain period of time, and the actuator 23 can be operated. For example, it is effective when washing the car of the agricultural work machine 2 or when it is desired to get off the tractor 1 and check the operation of the actuator 23 of the agricultural work machine 2. The fixed time that can be used here is considered to be several minutes to several tens of minutes, although it depends on the capacity of the capacitor 85.

10A and 10B show a view in the third embodiment of the remote control operation device for agricultural work machines of the present invention, in which FIG. 10A is a front view showing an operation panel 31 of a remote control operation unit 330, and FIG. 10B is a front view showing an operation panel 31 of a remote control operation unit 330, and FIG. 10B is a battery 201 mounted. It is a schematic rear view including the block diagram of the remote control operation unit 330 at the time, and (c) shows the schematic rear view including the block diagram when the power supply connection component 340 which is a DC adapter is attached instead of the battery 201. In the third embodiment, as compared with the first embodiment and the second embodiment, the control by the connection determination of the power supply connection component is added, and the voltage detection unit 311 is added. In the third embodiment, the parts to be added to the first and second embodiments and the different parts will be described, and the same parts as those in the first and second embodiments are designated by the same reference numerals.

As shown in FIG. 10A, the operation panel 31 of the remote control operation unit 330 includes a power button 32a, an operation button 32b, and an indicator light 318. These configurations can also be applied to the remote control operation unit 30 of the first and second embodiments.

The power button 32a is provided on the upper part of the operation panel 31, and by pressing the button, the power of the remote control operation unit 330 can be turned from OFF (OFF) to ON (ON) or from ON to OFF. At this time, the power can be turned on by pressing and holding for a certain period of time (for example, within a few seconds) so that the power is not turned on by mistake.

The operation buttons 32b are switches for operating the equipment on the farm work machine 2 side such as the actuator 23 of the farm work machine 2, and a plurality of the operation buttons 32b are arranged as necessary. For example, the safety can be enhanced by operating the actuator 23 only while pressing the operation button 32b.

The indicator light 318 is arranged at an easy-to-understand position on the operation panel 31, and is arranged next to the power button 32a in FIG. 10A. The indicator light 318 can be applied as an indicator of a power supply status, a communication status, and a battery capacity. Specific examples will be described later.

As shown in FIGS. 10B and 10C, the remote control operation unit 330 includes a voltage detection unit 311, a remote control operation unit control unit 312, a transmission / reception unit 315, and a wiring 316.

The voltage detection unit 311 detects the voltage between the contact 41a of the battery 201 and the power supply connection component 340. That is, in the state of FIG. 10B in which the battery 201 is attached to the battery storage unit 35 of the remote control operation unit 330, the (output) voltage of the battery 201 is detected via the wiring 316. If it is in series, the voltage at the end of the series is detected, and if it is in parallel, the voltage between the batteries 201 is detected. Further, in the state of FIG. 10C in which the power supply connection component 340 is attached to the battery storage unit 35 of the remote control operation unit 330, the contact 41a of the battery storage side connection unit 41 corresponding to the battery 201 (output). ) The voltage is detected via the wiring 316. The voltage detection unit 311 can be composed of, for example, an IC or a resistor.

The remote control operation unit control unit 312 is composed of a CPU or the like and controls the remote control operation unit 330, and performs the control of FIG. 11 described later based on the voltage detected by the voltage detection unit 311. It also controls the transmission / reception unit 315 to transmit a signal by the operation button 32. The voltage detection unit 311 may be configured in the remote control operation unit control unit 312.

The transmission / reception unit 315 wirelessly transmits the operation signal by the operation button 32 to the wireless transmission / reception unit 21 on the farm work machine 2 side. Further, if necessary, the transmission / reception unit 315 can wirelessly receive the information from the control unit 22 from the wireless transmission / reception unit 21 and send it to the remote control operation unit control unit 312.

The power supply connection component 340 has the same shape as the power supply connection component 40 of Examples 1 and 2, but as will be described later, the voltage between the contacts 41a (B in FIGS. 3 and 9) is changed to the voltage of the battery 201. Set it so that it is larger than the comparison. Other than that, it is the same as the power supply connection component 40.

When the battery 201 is used as a power source, the remote control operation unit 330 has a function of turning off the standby mode or the power supply after a certain period of time in order to reduce the power consumption of the battery. An example of this case is shown in S110 to S118 of FIG. 11 which will be described later. Here, when the standby mode or the power is turned off, the actuator 23 cannot be moved immediately even if the operation button 32 of the remote controller operation unit 330 is pressed. If the power is off, it is necessary to turn the power on again, and if it is in the standby mode, control for canceling the standby mode is required, which requires a certain period of time. The configuration of the remote control operation unit 330 other than that described in the third embodiment is the same as that of the remote control operation unit 30 described in FIGS.

FIG. 11 is a flowchart showing the control in the third embodiment of the remote control operation device for agricultural work machines of the present invention. The control of FIG. 11 is performed by the control unit 312 for the remote control operation unit.

First, when the control is started (S101), it is determined whether or not the power supply connection component 340 is connected to the remote controller operation unit 330 (S102). The determination of S102 may be made after pressing the power button 32a. The determination of S102 will be described later. As a result, if it is determined that the power supply connection component 340 is connected, the power supply of the remote controller operation unit 330 is turned on (S103), and the DC adapter mode is set (S104).

This state is the same as the state (S111) immediately after the battery 201 is turned on by the power button 32a when the battery 201 is attached. Further, on the agricultural work machine 2 side as well, when the wireless transmission / reception unit 21 and the control unit 22 are OFF, information is received from the transmission / reception unit 315 and these are turned ON. In this state, continuous communication is performed between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side. At this time, if the operation button 32b is operated, the actuator 23 can be immediately operated with good response. During this control, unlike S111 described later, the standby mode is not entered. Therefore, the control of S103 and S104 needs to be set as a control different from the control of S111.

On the other hand, as another control method, there is a control method in which the DC adapter mode is continued while utilizing the control of S110 to S113 described later. As one of the standby mode conditions, when the operation button 32 is not operated for a certain period of time, the mode shifts to the standby mode. However, at intervals shorter than this fixed time, the power signal is replaced with the signal input by the operation of the operation button 32. It adds a control that gives a signal such as, and prevents the transition to standby mode. If it is a power signal, for example, by pressing and holding the power button 32a, a signal for a time shorter than the reaction time is given to prevent the power from being turned off by this signal and to shift to the standby mode. To prevent.

Further, this state is maintained as long as it is determined (S105) that the power supply connection component 340 is connected to the remote control operation unit 330. Then, when it is determined that the power supply connection component 340 is not connected to the remote control operation unit 330, the power supply of the remote control operation unit 330 is turned off (S106). This is the same as the state of S118 in which the power button 32a is turned off when the battery 201 is installed, and communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side is not performed.

The determination of S102 and S105 described above is performed by the voltage detected by the voltage detection unit 311. Batteries generally have a range of actual voltages relative to their rated (nominal) voltage. For example, if the rated voltage displayed is a battery with a DC of 1.5V, the actual voltage may have a maximum of about 1.7V, and as it is used, the voltage drops to 1.0V or less. Is.

Here, the voltage between the contacts 41a of the power supply connection component 340 is set to be within the effective voltage that can be operated by the control unit 312 for the remote control operation unit and higher than the voltage due to the assumed battery 201. As a result, when this voltage is detected by the voltage detection unit 311 it is possible for the remote control operation unit control unit 312 to determine whether or not the power supply connection component 340 is connected due to the difference in the voltage.

For example, when three 1.5V batteries 201 are connected in series and the rated voltage is 4.5V, the actual maximum voltage of the batteries is 1.7 (V) x 3 = 5.1 (V). ) Degree is expected. At this time, if a voltage higher than this, such as 5.2 (V), is output between the contacts 41a of the power supply connection component 340, the voltage due to the battery 201 and the voltage of the power supply connection component 340 can be distinguished. .. That is, the maximum voltage output by the assumed battery 201 <the voltage output between the contacts 41a of the power supply connection component 340.

Further, the control unit 312 for the remote control operation unit may be set to operate at any of the above voltages. For example, in the above-mentioned example, it is sufficient to operate in the range of up to about 10V.

If the power supply of the remote controller operation unit 330 is continuously turned on by the DC adapter mode of S104, the operator can immediately operate the output device such as the actuator 23 with the operation button 32b. At this time, since the power connection component 340 is connected to the power supply of the tractor 1, the power can be secured from the battery 11 or the like, so that the capacity is larger than that of the battery 201 and the problem of power consumption is lessened.

In S102 of FIG. 11, if it is determined that the power supply connection component 340 is not connected, it is determined whether or not the power supply button 32a is turned on (S110). When a signal that becomes an ON condition such as pressing the power button 32a is detected, the power of the remote controller operation unit 330 is turned ON (S111). Further, on the agricultural work machine 2 side as well, when the wireless transmission / reception unit 21 and the control unit 22 are OFF, information is received from the transmission / reception unit 315 and these are turned ON. In this state, continuous communication is performed between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side. If the power connection component 340 is not connected, it is assumed that a battery will be used. If the battery 201 is not inserted, or if the battery 201 has no capacity, the power button will not be turned on and the power of the remote controller operation unit 330 will not be turned on.

On the other hand, if the power button is turned off by pressing the power button 32a again while the power is on, the power of the remote controller operation unit 330 is turned off (S112, S118). Further, if the power is on as it is, the standby mode condition is determined (S113), and if the condition is met, the standby mode is set (S114).

The standby mode condition changes the communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side from continuous communication to intermittent communication when the operation button 32 is not operated for a certain period of time. It is something to switch. The intermittent communication in the standby mode communicates at intervals as compared with the continuous communication of S111, and is, for example, an interval of about several seconds to several tens of seconds. By switching to intermittent communication, the consumption of the battery 201 can be suppressed as compared with the case of continuous communication.

To return from the standby mode, if the operation button 32 is pressed during the standby mode, the intermittent communication is switched to the continuous communication of S111, and normal operation can be performed. However, when switching to continuous communication, it takes some time, and the operator does not feel that the actuator 23 operates with good response.

On the other hand, if the power button 32a is turned off by pressing the power button 32a again for a certain period of time or longer in the standby mode, the power of the remote controller operation unit 330 is turned off (S115, S118). On the other hand, if the power is on as it is, the auto power off mode condition is determined (S116), and if the condition is met, the auto power off mode is set and the power supply of the remote controller operation unit 330 is turned off (S117, S118).

The auto power off mode condition is to set the auto power off mode when the operation button 32 is not operated for a certain period of time. This is the same as when the power is turned off by operating the power button 32a. At this time, the power of the remote control operation unit 330 is turned off, and communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side is not performed. As a result, the consumption of the battery 201 becomes extremely small. Further, the reception function of the wireless transmission / reception unit 21 on the farm work machine 2 side can also be turned off, and the power supply of the control unit 22 may be turned off. The fixed time of this auto power off mode condition is longer than the time for transitioning to the standby mode condition, and can be applied, for example, between several minutes and several hours.

As another auto power-off mode condition, in the standby mode, intermittent communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side (due to radio waves not reaching, etc.) If it cannot be done for a certain period of time, the auto power off mode may be set. This is because if communication with the wireless transmission / reception unit 21 on the farm work machine 2 side is not possible, it is assumed that the operation cannot be performed even if the standby mode is restored. The fixed time in this case is shorter than the fixed time when the operation button 32 is not operated, for example, several minutes to several tens of minutes.

To return from the auto power off mode, it is necessary to perform an ON operation by pressing the power button 32a as in S110. When the power button 32a is pressed (in some cases, for a certain period of time), the power of the remote control operation unit 330 is turned on. Further, also on the agricultural work machine 2 side, it is necessary to turn on the reception function of the wireless transmission / reception unit 21 and the control unit 22 when they are turned off. Therefore, the recovery from the auto power off mode takes longer to start up than the recovery from the standby mode.

As another control, when the voltage of the battery 201 drops, the indicator lamp 318 notifies the battery 201, and when the voltage drops further than that, the control of turning off the power of the remote control operation unit 330 may be applied. .. This is because the capacity of the battery runs out as the voltage of the battery 201 drops. For example, the above control is performed when a voltage of about several percent of the rated voltage drops.

The display of the indicator lamp 318 can indicate the state by changing the display color or displaying lighting and blinking separately. For example, when the power of the remote control operation unit 330 is ON, it lights up in green, when the wireless transmission / reception unit 21 on the farm work machine 2 side is within the range of radio waves, it lights up in red, and when the battery capacity is low, it lights up. It blinks red and turns off when the power of the remote control operation unit 330 is off.

12A and 12B show a view in Example 4 of the remote control operation device for agricultural work machines of the present invention, in which FIG. 12A shows a side view of the power supply connection component 440, and FIG. 12B shows a front view of the power supply connection component 440. (C) shows a schematic rear view including a block diagram when the battery 201 is mounted on the remote controller operation unit 430. In Example 4, the points different from those in Example 3 will be described, and the same parts as in Examples 1 to 3 are designated by the same reference numerals.

In the fourth embodiment, the control of the determination of the power connection component connection in S102 and S105 of FIG. 11 is different from that in the third embodiment. In the fourth embodiment, it is determined not by the difference in voltage but by the connection of the contacts, and the power supply connection component 440 has a configuration for that purpose.

The power supply connection component 440 has a plate-shaped contact connection member 410. The contact connecting member 410 is formed of a material (electric conductor) that conducts electricity, such as a copper plate. The contact 417 is formed inside the packing 480. In FIG. 12, the contact connection member 410 is formed on the storage side (front side) surface of the cover portion 442 between the battery storage side connection portion 441 and the packing 480. The battery storage side connection portion 441, the cover portion 442, and the packing 480 have the same functions as the battery storage side connection portion 41, the cover portion 42, and the packing 80 described with reference to FIG. The shape may be changed as necessary to secure space for the. The power supply connection component 440 does not need to change the output voltage as in the power supply connection component 340 of the third embodiment. The configuration of the power supply connection component 440 other than that described in the fourth embodiment is the same as that of the power supply connection component 40 described with reference to FIG. 2 and the like.

The remote control operation unit 430 includes a power supply connection component connection confirmation input unit 411, a remote control operation unit control unit 412, a transmission / reception unit 315, a wiring 416, and a contact 417. The configuration of the remote control operation unit 430 other than that described in the fourth embodiment is the same as that of the remote control operation unit 30 described in FIGS.

The two wires 416 are each connected to two contacts 417 at the tip. The two contacts 417 have a certain distance, and when the power supply connection component 440 is connected to the remote control operation unit 430, they are electrically connected via the contact connection member 410. Therefore, the contact connecting member 410 has a length corresponding to the distance between at least two contacts 417. Further, the two contacts 417 may be expanded and contracted by using an elastic member in the connection direction (backward direction of the remote controller operation unit 430) so that the two contacts 417 can be easily connected to the contact connection member 410. In FIG. 12C, the contact 417 is installed above the battery storage unit 35 in the remote control operation unit 430, and when the power supply connection component 440 is attached to the remote control operation unit 430, there are two contact connection members 410. It is arranged at a position where the contact 417 is connected. At this time, the two contacts 417 are also located inside the packing 480.

The power supply connection component connection confirmation input unit 411 detects when the two contacts 417 are electrically connected via the contact connection member 410.

The remote control operation unit control unit 412 is composed of a CPU or the like and controls the remote control operation unit 430, and performs control based on the information detected by the power supply connection component connection confirmation input unit 411. Further, the transmission / reception unit 315 also controls to transmit a signal by the operation button 32. The power supply connection component connection confirmation input unit 411 may be configured in the remote control operation unit control unit 412.

The determination of the power connection component connection in S102 and S105 of FIG. 11 will be described. When the battery 201 is mounted in the battery storage unit 35 of the remote control operation unit 430, the two contacts 417 are separated from each other, and nothing intervenes between them. Therefore, the power connection component connection confirmation input unit 411 is between the contacts. Do not check the energization. In this case, the remote control operation unit control unit 412 determines that the power supply connection component 440 is not connected. On the other hand, when the power connection component 440 is attached to the battery storage unit 35 of the remote control operation unit 430, the two contacts 417 on the remote control operation unit 430 side are connected via the contact connection member 410 on the power connection component 440 side to connect the power supply. The component connection confirmation input unit 411 detects energization between the contacts. In this case, the remote control operation unit control unit 412 determines that the power supply connection component 440 is connected.

13A and 13B show a diagram in Example 5 of the remote control operation device for agricultural work machines of the present invention, in which FIG. 13A shows a front view of the power supply connection component 540, and FIG. 13B shows a battery 201 mounted on the remote control operation unit 530. A schematic rear view including a block diagram of the time is shown. In Example 5, the points different from those in Example 3 will be described, and the same parts as in Examples 1 to 3 are designated by the same reference numerals.

In the fifth embodiment, the control of the determination of the connection of the power supply connection component in S102 and S105 of FIG. 11 is different from that of the third embodiment. In the fourth embodiment, it is determined not by the difference in voltage but by the fact that the micro switch is pressed, and the power supply connection component 540 has a configuration for that purpose.

The power connection component 540 has a switch contact surface 510. The switch contact surface 510 may have a protrusion shape, a flat shape, or a dent shape, if necessary. The switch contact surface 510 is formed inside the packing 580. In FIG. 13, the cover portion 542 is formed on the storage side (front side) surface between the battery storage side connection portion 541 and the packing 580. The battery storage side connection portion 541, the cover portion 542, and the packing 580 have the same functions as the battery storage side connection portion 41, the cover portion 42, and the packing 80 described in FIG. 2 and the like, but because of the switch contact surface 510. The shape may be changed as necessary to secure space for the. Further, the power supply connection component 540 of the fifth embodiment does not need to change the output voltage as the power supply connection component 340 of the third embodiment. The configuration of the power supply connection component 540 other than that described in the fifth embodiment is the same as that of the power supply connection component 40 described with reference to FIG. 2 and the like.

The remote control operation unit 530 includes a power supply connection component connection confirmation input unit 511, a remote control operation unit control unit 512, a transmission / reception unit 315, a wiring 516, and a micro switch 517. The configuration of the remote control operation unit 530 other than that described in the fifth embodiment is the same as that of the remote control operation unit 30 described in FIGS.

The two wires 516 are connected to the microswitch 517 at their respective tips. Then, when the micro switch 517 is not pressed and is OFF, the two wires 516 are not connected, and when the micro switch 517 is pressed and turned ON, the two wires 516 are connected. The micro switch 517 protrudes in the direction of contact with the switch contact surface 510 (backward direction of the remote control operation unit 530), and when pushed by the switch contact surface 510, the micro switch 517 is in the front direction of the remote control operation unit 530 (battery storage unit 35). It retracts to the back side) and turns ON. Then, when it is not pushed by the switch contact surface 510, it is restored in the protruding direction by using an elastic member or the like so that the switch is turned off. In FIG. 13B, the micro switch 517 is installed above the battery storage unit 35 in the remote control operation unit 530, and when the power supply connection component 540 is attached to the remote control operation unit 530, the switch contact surface 510 is formed. It is arranged at a position where the micro switch 517 is pressed to turn it on. At this time, the micro switch 517 is also located inside the packing 580.

The power supply connection component connection confirmation input unit 511 detects when the micro switch 517 is pressed to turn it on and the two wirings 516 are electrically connected.

The remote control operation unit control unit 512 is composed of a CPU or the like and controls the remote control operation unit 530, and performs control based on the information detected by the power supply connection component connection confirmation input unit 511. Further, the transmission / reception unit 315 also controls to transmit a signal by the operation button 32. The power supply connection component connection confirmation input unit 511 may be configured in the remote control operation unit control unit 512.

The determination of the power connection component connection in S102 and S105 of FIG. 11 will be described. When the battery 201 is mounted in the battery storage unit 35 of the remote control operation unit 530, the micro switch 517 is not pressed, and the power supply connection component connection confirmation input unit 511 does not confirm the energization between the two wirings 516. In this case, the remote control operation unit control unit 512 determines that the power supply connection component 540 is not connected. On the other hand, when the power supply connection component 540 is attached to the battery storage unit 35 of the remote control operation unit 530, the micro switch 517 on the remote control operation unit 530 side is pushed by the switch contact surface 510 on the power supply connection component 540 side to turn on, and the power supply is turned on. The connection component connection confirmation input unit 511 detects the energization between the two wirings 516. In this case, the remote control operation unit control unit 512 determines that the power supply connection component 540 is connected.

14A and 14B show a view in the sixth embodiment of the remote control operation device for agricultural work machines of the present invention, in which FIG. 14A is a side view before connecting the power supply connection component 640 to the remote control operation unit 30, and FIG. 14B is the remote control operation unit. A side view showing a state in which the power supply connection component 640 is connected to the remote controller 30, and a rear view showing a state in which the power supply connection component 640 is connected to the remote controller operation unit 30 (c). FIG. 15 also shows a diagram of the sixth embodiment of the remote control operation device for agricultural work machines of the present invention, in which (a) is a front view of a state in which the remote control operation unit 30 to which the power connection component 640 is connected is attached to the power holder 700. B) shows a side view of the remote control operation unit 30 to which the power supply connection component 640 is connected attached to the power supply holder 700, and (c) shows a front view of the power supply holder 700.

In the sixth embodiment, the points different from those described mainly in FIGS. 1 to 8 (Example 1) will be described.

The remote control operation unit 30 is the same as the remote control operation unit 30 described with reference to FIG. 2 and the like.

The power supply connection component 640 has a main body portion 649 composed of a battery storage side connection portion 641 and a cover portion 642. These can be applied with the same outer shape as the main body 49 composed of the battery storage side connection 41 and the cover 42 of the power connection component 40 described with reference to FIG. 2, and the contact 41a is also the battery storage side connection 641. It has on the side of. On the other hand, a wireless power receiving unit 670 is provided inside the main body unit 649 composed of the battery storage side connection unit 641 and the cover unit 642. Further, the power supply connection component 640 does not have the harness portion 43 and the connectors 44 and 46 unlike the power supply connection component 40. Further, the power converted by the wireless power receiving unit 670 can be output from the contact 41a and supplied as the power supply power of the remote controller operating unit 30 instead of the battery 201.

The power supply holder 700 is different from the holder 100 described with reference to FIGS. 7 and 8 as follows. First, instead of the second convex portion 122 and the third convex portion 123 of the holder 100, the wireless power feeding side convex portion 722 is provided. A wireless power feeding unit 770 is installed in this portion (inside) and is connected to a harness portion 743. The height of the wireless power feeding side convex portion 722 is the same as that of the first convex portion 121. The harness portion 743 is connected to the outside of the power supply holder 700 from below the wireless power feeding portion 770 through the groove 170. The tip of the harness portion 743 on the opposite side of the wireless power supply portion 770 is connected to the power connector 44 and the external connector 46, and this point is the same as that of the harness portion 43 described with reference to FIG.

Power can be transmitted wirelessly between the wireless power feeding unit 770 and the wireless power receiving unit 670. Examples of the types of wireless power feeding include "electromagnetic induction", "magnetic resonance", and "microwave / laser light" methods. The "electromagnetic induction" method is a method of transmitting electric power from the coil on the primary side to the coil on the secondary side by electromagnetic induction. The "magnetic resonance" method is a method of transmitting electric power using resonance. The "microwave / laser light (wireless)" method transmits electricity using microwaves or laser light. The wireless power feeding unit 770 and the wireless power receiving unit 670 are configured to fit the selected method.
