Make it easy to take measures such as increasing the vehicle speed obtained from the rotational speed of the traveling device and improving work efficiency while checking the information on the vehicle speed obtained from the rotational speed of the traveling device. Become.

Moreover, with the above configuration, for example, in order to display the vehicle speed obtained from the rotation speed of the traveling device in the large display area on the auxiliary display unit, the cost increases as in the case where the auxiliary display unit is configured in a large size. There is no disadvantage incurred, and the vehicle speed obtained from the rotational speed of the traveling device can be displayed in an easy-to-understand manner while making the entire device inexpensive.
Accordingly, it has become possible to provide a combine display device that can improve the work efficiency by displaying the vehicle speed obtained from the rotational speed of the traveling device in an easily understandable manner while having a low-cost configuration as a whole.
According to the first characteristic configuration, the auxiliary display unit is provided at a lower portion of the main display unit, and a pair of sub display units are arranged in parallel on both the left and right sides of the main display unit, and are displayed on the main display unit. By displaying notification information other than the plurality of types of notification information displayed on the notification information and the auxiliary display unit on the pair of sub display units, various types of notification information as notification information to be notified to the operator are displayed on the main display. In each of the display unit, the auxiliary display unit, and the pair of sub-display units, it is possible to appropriately display in an easy-to-see state for the operator.
In the combine, the engine load is important notification information similar to the vehicle speed obtained from the rotation speed of the traveling device among the notification information to be notified to the worker. According to the first characteristic configuration, the main display unit By configuring the engine load to be displayed in addition to the vehicle speed obtained from the rotational speed of the traveling device, it becomes easy to confirm the correspondence between the engine load and the vehicle speed obtained from the rotational speed of the traveling device. For example, when the vehicle speed obtained from the rotational speed of the traveling device is a lower speed, the engine load is a smaller load, and the vehicle speed obtained from the rotational speed of the traveling device can be increased. It is possible to easily determine whether the engine load is a large load and the engine load cannot be increased, and the usability is improved.
According to the first characteristic configuration, the engine load display unit moves the load display instruction unit along the load display setting path extending between the minimum load display position and the maximum load display position. By visually observing the moving state of the display instruction unit, the engine load can be easily determined.
In other words, if it is a display form that expresses the engine load numerically, it is difficult for the operator to intuitively understand the magnitude of the engine load. Which position between the minimum load display position and the maximum load display position the load display instruction section is in, in other words, the current engine load is within the load changeable range between the minimum load and the maximum load. Therefore, it is easy to understand how much the engine load is.
According to the first characteristic configuration, the engine load display unit can be arranged by effectively using the space on the outer side of the speed display setting route.
According to the first characteristic configuration, when the engine load sequentially increases from the lowest load, first, the lighting unit at the lowest load display position is switched from the unlit state to the lighting state, and then the lighting unit at the lowest load display position. The lighting part adjacent to the maximum load display position side switches from the unlit state to the lighting state, and then the lighting part adjacent to the maximum load display position side from the lighting part switches from the unlit state to the lighting state. In this way, as the engine load increases, the lighting unit that switches from the unlit state to the lit state sequentially moves to the maximum load display position side. Then, the operator can read the engine load from the position of the lighting unit that switches from the unlit state to the lit state.
With such a configuration, the change in the position of the lighting unit that switches from the unlit state to the lit state moves to the next lighting unit after the engine load fluctuates to some extent. In other words, even if the engine load changes slightly, the display state of the display section for engine load does not change, and the display state of the display section for engine load does not change frequently in response to fine changes in engine load. Becomes easy to see.
Therefore, since the vehicle speed obtained from the engine load and the rotation speed of the traveling device is displayed at a location close to it, the operator does not have to move his / her line of sight when reading such information, so it can be read efficiently. It becomes.

A lamp-type display unit is provided below the pair of sub-display units. To the point it is there.
According to the second characteristic configuration, the work speed display unit moves the indicator needle along the semicircular speed display setting path protruding upward, thereby obtaining the vehicle speed obtained from the rotational speed of the traveling device. From the display, the operator can read the vehicle speed obtained from the rotational speed of the traveling device from the position of the indicator needle.
By configuring in this way, the path length of the speed display setting path can be increased as much as possible by effectively using the limited display space, for example, compared to a linear path, etc. It is possible to display the vehicle speed obtained from the rotational speed of the traveling device in a state where the resolution is increased by increasing the unit movement amount of the indicator needle as much as possible when the obtained vehicle speed changes by a unit amount.
Therefore, the vehicle speed obtained from the rotational speed of the traveling device can be displayed in a state where the vehicle speed can be accurately read with as high a resolution as possible.
In addition, a display form that expresses the work speed numerically makes it difficult for the operator to intuitively understand the magnitude of the work speed. However, with the above configuration, there is no such disadvantage, and the indicator needle is the lowest. Which position is between the speed display position and the maximum speed display position, in other words, the vehicle speed obtained from the rotational speed of the current traveling device is within the speed adjustable range between the minimum speed and the maximum speed. It is easy to understand sensuously how fast the speed is.

The control unit 28 is configured to drive the cylinders and the motors based on the information of the sensors to execute various controls such as cutting height control, unloader control, threshing control, and vehicle speed control. ing.

  And the said control part 28 becomes a structure which implements the display control which controls the display state in the display unit C. FIG. Hereinafter, the specific content of the display control by the control unit 28 will be described with reference to the flowchart of FIG.

  The control unit 28 operates the work speed meter 12 so as to correspond to the current work speed based on the detection information of the vehicle speed sensor S4, and corresponds to the rotation speed of the engine E based on the detection information of the engine rotation speed sensor S5. Then, the engine speedometer 14 is operated, and the fuel meter 15 is operated so as to correspond to the fuel remaining amount in the fuel tank based on the detection information of the fuel remaining amount sensor S9 (step 1).

  When the description of the display of the work speed is added, the control unit 28 causes the turning angle of the indicator needle 12a of the work speed meter 12 to be a turning angle corresponding to the current working speed detected by the vehicle speed sensor S4. The operation of the rotation drive unit of the work speed meter 12 is controlled.

  Similarly, the rotation speed of the indicator needle 14a of the engine rotation speed meter 14 is the rotation angle corresponding to the current engine rotation speed detected by the engine rotation speed sensor S5. The operation of the rotation drive unit of the engine rotation speed meter 14 is controlled. Similarly, with respect to the fuel gauge, the fuel gauge 15 so that the turning angle of the indicator needle 15a of the fuel gauge 15 becomes a turning angle corresponding to the current remaining fuel amount detected by the remaining fuel amount sensor S9. The operation of the rotation drive unit is controlled.

  Next, based on the command information of the sub-shift switch 9 and the sub-shift neutral switch 10, the operation of the sub-shift hydraulic cylinder 65 is controlled so that the corresponding shift state is established, and the sub-transmission device 42 is shifted. However, since it is possible to determine the current shift state of the current sub-transmission device 42 based on the detection information of the sub-transmission sensor S10 at that time, the sub-transmission display unit C4 presents the current shift state based on the determination result. Which shift state the sub-transmission device 42 is in is displayed (step 2). That is, the illumination lamp 73 is turned on and brightly displayed for any of the high-speed display portion 16, the low-speed display portion 17, and the neutral display portion 18 of the auxiliary transmission display portion C 4, and the illumination lamp 73 is turned off for the others. And darken it.

  Further, the control unit 28 controls the operation of the cutting shift hydraulic cylinder 66 so as to be in a corresponding shift state based on the command information of the cutting shift changeover switch 11 and shifts the cutting transmission 43. Based on the detection information of the cutting shift sensor S11, it is possible to determine which shift state the current cutting transmission 43 is in. Therefore, on the cutting shift display C5, the current cutting transmission is displayed based on the determination result. Which shift state 43 is displayed is displayed (step 2). Specifically, the illumination lamp 73 corresponding to one of the high-speed display portion 19 and the low-speed display portion 20 of the cutting shift display portion C5 is turned on, and the other illumination lamps 73 are turned off.

  Then, in a normal state where the combine is operating normally, the control unit 28 displays the plurality of segment display units 13a in the engine load indicator 13 from one end side in the arrangement direction, for example, as shown in FIG. The engine load is displayed by sequentially increasing the number of segment display units 13a to be displayed, and in an abnormal state where an abnormality has occurred in the combine, all of the plurality of segment display units 13a are flashed and displayed (step 3, 4).

  The structure for detecting the engine load will be described. In this combine, when the engine E is in a no-load state where no load is applied, the operator performs an accelerator operation so that the engine speed is set in advance. The accelerator operation position of the engine E is adjusted so as to become the set reference rotation speed. When the engine rotation speed becomes the reference rotation speed, the position is fixed at the accelerator operation position and the subsequent work is performed. ing.

  When a load is applied to the engine E, the engine rotation speed decreases from the reference rotation speed in accordance with the magnitude of the engine load. It is set as map data in a state where the magnitude of the engine load is associated. Therefore, the control unit 28 calculates the difference between the engine rotation speed detected by the engine rotation speed sensor S5 and the reference rotation speed, that is, the engine rotation speed decrease amount, and calculates the engine rotation speed decrease amount and the The engine load is determined based on the map data.

  When displaying the engine load thus obtained, the control unit 28 displays the 13 segment display units 13a from the first one located at one end in the arrangement direction, that is, the counterclockwise end. The engine load is displayed in such a manner that the number of segment display portions 13a to be lit up is sequentially increased. When the engine load is an appropriate load, the green segment display portion 13a is lit, and when the engine load increases and exceeds the set value and becomes a caution load state, in addition to the eight green segment display portions 13a, yellow is displayed. The segment display portion 13a lights up. Furthermore, when the engine load increases and exceeds the upper limit value, the red segment display unit 13a is turned on in addition to the eight green segment display units 13a and the three yellow segment display units 13a. Become.

  Further, in a normal state where the combine is operating normally, the control unit 28 performs display processing for displaying various types of notification information as described above on the auxiliary display unit C3 (step 5).

In this display process, every time the mode changeover switch 80 is pressed, the plural information display state and the minority information display state are alternately switched.
Specifically, in the multiple information display state, as shown in FIG. 10 (a), as the multiple types of notification information, the grain stored in the Glen tank 3 (in the figure, expressed as “fir”). ), The amount of the sorting processed product on the swing sorting plate 54 detected by the sheave sensor S8 (denoted as “sheave” in the figure), and the cooling water in the engine E detected by the water temperature sensor S7. Each water temperature information is displayed. In addition to the information, the left and right turn signal displays 74, the hour meter 75 indicating the combined operation time of the combine, the charge alarm display 76 indicating that the battery charge is low, and the oil alarm display 77 indicating the oil abnormality Are also displayed side by side. Further, in the state of switching to the minority information display state, every time the display changeover switch 81 is pushed, the selected processed product amount, the grain storage amount, and the temperature of the cooling water, as shown in FIG. In a state where any of the information is enlarged and displayed, the display contents are sequentially switched in a preset order.

  Then, in an abnormal state where the combine is abnormal, the control unit 28 blinks and displays all the thirteen segment display units 13a in the engine load display meter 13 (step 6). The abnormal state here is a case where an abnormality that makes it difficult to continue the cutting operation has occurred in any part of the combine. For example, an exhaust wall clogging detection switch There is an abnormal discharge clogging or the like in which the exhaust straw is clogged in the exhaust straw cutter unit 64 when S15 is turned on. In addition to this waste straw clogging, there are abnormalities such as clogging of harvested cereal grains in the cutting unit 1 and abnormal overheating of the engine.

  Moreover, the control part 28 respond | corresponds to the said abnormality instead of several types of alerting | reporting information, such as above-mentioned stored grain amount, the amount of sorting processed materials, and water temperature, in the abnormal state where the abnormality has generate | occur | produced in the combine. Message information is displayed on the auxiliary display C3 (step 7). When an abnormality occurs in which the above-described waste straw is clogged, as shown in FIG. 10 (b), message information for dealing with the abnormality that occurred at that time, for example, “the waste straw cutter is clogged with straw Message information like "Please remove the wall" is displayed.

  Therefore, when the multiple information display state is selected in the normal state in which the combine is operating normally, the display unit C displays all the notification information that the operator needs when continuously executing the cutting operation. They can be displayed at the same time, eliminating the troublesome trouble of switching display contents during the work. In addition, when an abnormality occurs, all of the 13 segment display units 13a in the engine load indicator 13 are displayed in a blinking manner. Even when the cutting operation is performed while watching, it is easy to recognize that an abnormality has occurred. Moreover, since the message information corresponding to the abnormality that has occurred is displayed, the subsequent response can be taken quickly and accurately.
