Description

The present invention relates to a combine harvester that allows access to grain stored in a grain tank even from remote locations.

Combine harvesters equipped with means for checking the quality of harvested grain are known. For example, the combine harvester described in Patent Document 1 has a maintenance inspection hatch (an inward-opening door) on the side wall of the grain tank, allowing grain inside the grain tank to be removed through the inspection hatch. Furthermore, the combine harvester described in Patent Document 2 has a grain removal opening at the bottom of the grain tank, allowing grain inside the grain tank to be removed through the grain removal opening. Furthermore, the combine harvester described in Patent Document 3 has a grain sampling device and quality measurement device inside the grain tank, allowing the quality of the grain to be checked without removing the grain from the grain tank.

However, with the combine harvesters described in Patent Documents 1 and 2, not only is it difficult to remove grains unless the grains have piled up close to the inspection hatch or grain outlet, but if the height of the grain pile reaches the inspection hatch or grain outlet, there is a risk that the grains will fall out when the inspection hatch or grain outlet is opened. Furthermore, with the combine harvester described in Patent Document 3, there is a risk that measurement accuracy will be reduced if straw dust gets mixed in, due to the characteristics of the quality measurement device. Furthermore, because the harvested grains cannot be directly touched or seen, it is difficult to check their texture, appearance, size, hardness, etc.

The present invention was created in consideration of the above-mentioned current situation and with the aim of solving these problems.The invention of claim 1 is a combine harvester equipped with a grain tank for storing harvested grain, characterized in that it is equipped with a takeoff and landing section provided on the top of the grain tank from which an unmanned aerial vehicle can take off and land, and a grain transfer section capable of transferring the grain in the grain tank to the unmanned aerial vehicle.

Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 to 3, reference numeral 1 denotes a combine harvester. The combine harvester 1 comprises a harvesting unit 2 that harvests stalks and culms, a threshing unit 3 that threshes and sorts grains from the harvested stalks and culms, a grain tank 4 that stores the sorted grains, an auger 5 that transports the grains in the grain tank 4 outside the machine, a post-processing unit 6 that processes the threshed stalks, a driving unit 7 on which an operator rides, and a crawler-type traveling unit 1a.

The threshing section 3 comprises a threshing feed chain 8 that supplies the stalks harvested by the harvesting section 2 to the threshing section 3; a straw discharge chain 9 that receives the threshed stalks from the threshing feed chain 8 and supplies them to the post-processing section 6; a handling chamber (not shown) that threshes grains from the stalks transported by the threshing feed chain 8; a sorting chamber (not shown) that sorts the processed material leaking from the handling chamber into first-grade and second-grade grains while discharging dust such as straw outside the machine; a grain lifting and conveying device 10 that lifts and conveys the first-grade grains and deposits them into the grain tank 4; and a second-grade return device (not shown) that returns the second-grade grains upstream of the sorting chamber or to the handling chamber.

The combine harvester 1 of this embodiment has an automatic driving function, allowing for unmanned harvesting without an operator on board. In such unmanned harvesting operations, when checking the quality of the harvested grain at the start of work, conventionally, the harvesting operation would have to be interrupted and the work manager would have to go to the combine harvester 1 and remove the grain from the grain tank 4. However, in this embodiment, by configuring a grain air transport system 100 as shown in Figure 4, an unmanned aerial vehicle 120 such as a drone can be used to easily obtain the grain in the grain tank 4 even from locations far from the combine harvester 1.

The grain air transport system 100 shown in FIG. 4 includes a combine harvester 1, an unmanned aerial vehicle 120, and a mobile terminal 140 such as a smartphone used by a work manager. For example, in the case of the first embodiment described below, when a movement command is sent from the mobile terminal 140 to the unmanned aerial vehicle 120, the unmanned aerial vehicle 120 automatically flies from a base (not shown) to the combine harvester 1 by autopilot and lands on the grain tank 4 of the combine harvester 1. Furthermore, when an extraction command is sent from the mobile terminal 140 to the unmanned aerial vehicle 120 in this state, the unmanned aerial vehicle 120 sucks up the grain inside the grain tank 4. Thereafter, when a return command is sent from the mobile terminal 140 to the unmanned aerial vehicle 120, the unmanned aerial vehicle 120 automatically takes off from above the grain tank 4 of the combine harvester 1 by autopilot, automatically flies to the base, and lands at the base.

This makes it possible to easily obtain the grain stored in the grain tank 4 even from locations far from the combine harvester 1. Below, the configurations of the combine harvester 1, unmanned aerial vehicle 120, and mobile terminal 140 that realize this grain air transport system 100 will be described with reference to Figures 5 and 6.

As shown in FIG. 5, the combine harvester 1 is provided with a takeoff and landing section 20 that is located above the grain tank 4 and from which the unmanned aerial vehicle 120 can take off and land, and a grain transfer section 40 that can transfer grain from the grain tank 4 to the unmanned aerial vehicle 120. The grain transfer section 40 of the first embodiment is provided above the grain tank 4 and includes a temporary storage section 41 that temporarily stores grain supplied from the grain lifting and conveying device 10 into the grain tank 4, and a suction port 42 that enables the unmanned aerial vehicle 120 that has landed on the takeoff and landing section 20 to suck up the grain from the temporary storage section 41 via a suction pipe 121.

Specifically, as shown in Figure 5, the temporary storage section 41 in this embodiment has a box shape suspended from the ceiling of the grain tank 4, with a grain intake port 43 formed on one side opposite the grain inlet 10a of the grain lifting and conveying device 10, and a suction port 42 opening on the top. With this type of temporary storage section 41, some of the grains supplied from the grain lifting and conveying device 10 to the grain tank 4 are stored in the temporary storage section 41 via the grain intake port 43, thereby simplifying the configuration for storing grains in the temporary storage section 41.

In addition, the temporary storage section 41 of this embodiment is equipped with a partition plate 44 that hangs down from the ceiling and separates the suction port 42 and the grain intake port 43. This partition plate 44 prevents grains being dropped into the temporary storage section 41 from the grain lifting and conveying device 10 from directly hitting the suction pipe 121 of the unmanned aerial vehicle 120.

In addition, the temporary storage unit 41 of this embodiment is equipped with a shutter 45 that can open and close the bottom portion, and a motor 46 that opens and closes the shutter 45. This shutter 45 allows the grains temporarily stored in the temporary storage unit 41 to be returned to the grain tank 4 at any time. Furthermore, when there is no need to transfer grains to the unmanned aerial vehicle 120, the temporary storage of grains in the temporary storage unit 41 can be stopped by keeping the shutter 45 in an open state.

As shown in FIG. 6, the combine harvester 1 is equipped with a control unit 11 consisting of a CPU, ROM, RAM, I/O, etc. The control unit 11 is capable of wireless communication with the unmanned aerial vehicle 120 and the mobile terminal 140 via the communication unit 12. The input side of the control unit 11 is connected to a GPS 13 that detects the position of the combine harvester 1, an IMU 14 that detects the body attitude of the combine harvester 1, a yield sensor 15 that detects the harvesting status, and a landing detection sensor 16 that detects the landing of the unmanned aerial vehicle 120, while the output side is connected to the aforementioned motor 46 as well as a display unit 17 that can notify the approach of the unmanned aerial vehicle 120, etc.

When the control unit 11 receives a movement command from the mobile terminal 140, it transmits the position information of the combine harvester 1 to the unmanned aerial vehicle 120 as needed, and also receives the position information of the unmanned aerial vehicle 120 as needed. The control unit 11 also closes the shutter 45 to temporarily store the grain in the temporary storage unit 41.

When the landing detection sensor 16 detects the landing of the unmanned aerial vehicle 120, the control unit 11 transmits a landing confirmation signal. Furthermore, when the landing detection sensor 16 detects the takeoff of the unmanned aerial vehicle 120, the control unit 11 transmits a takeoff confirmation signal and opens the shutter 45 to return the grain in the temporary storage unit 41 to the grain tank 4.

The unmanned aerial vehicle 120 is equipped with a control unit 122 composed of a CPU, ROM, RAM, I/O, etc. The control unit 122 is capable of wireless communication with the combine harvester 1 and the mobile terminal 140 via the communication unit 123. The input side of the control unit 122 is connected to a GPS 124 that detects the position of the unmanned aerial vehicle 120, an IMU 125 that detects the attitude of the unmanned aerial vehicle 120, an altimeter 126 that detects the altitude of the unmanned aerial vehicle 120, and a grain sensor S that detects the amount of grain transferred from the grain tank 4. The output side is connected to a motor 128 that drives the propeller 127 and a pump 129 that sucks up grain from the temporary storage unit 41 via the suction pipe 121.

When the control unit 122 receives a movement command from the mobile terminal 140, it receives position information of the combine harvester 1 from the unmanned aerial vehicle 120 at any time, transmits the position information of the unmanned aerial vehicle 120 at any time, and flies the unmanned aerial vehicle 120 from the base to the combine harvester 1 and lands it on the grain tank 4 of the combine harvester 1 (departure and arrival unit 20).

When the control unit 122 receives an extraction command from the mobile terminal 140, it operates the pump 129 to have the unmanned aerial vehicle 120 suck up the grains in the temporary storage unit 41, and when the amount of grain sucked up reaches a predetermined amount, it stops the operation of the pump 129 and transmits a suction completion confirmation signal. Then, when the control unit 122 receives a return command from the mobile terminal 140, it causes the unmanned aerial vehicle 120 to take off from the grain tank 4 of the combine 1, fly it to the base, and then land it at the base.

The mobile terminal 140 is equipped with a communication unit 141 that can wirelessly communicate with the combine harvester 1 and the unmanned aerial vehicle 120. The mobile terminal 140 also includes a functional configuration realized through the cooperation of hardware and software (dedicated apps): a movement command means 142, an extraction command means 143, a return command means 144, and a status display means 145.

The movement command means 142 transmits movement commands to the combine 1 and the unmanned aerial vehicle 120 in response to a movement command operation by the user. The extraction command means 143 transmits an extraction command to the unmanned aerial vehicle 120 in response to a movement command operation by the user. However, if a landing confirmation signal is not received from the combine 1, the extraction command operation by the user is restricted. The return command means 144 transmits a return command to the unmanned aerial vehicle 120 in response to a return command operation by the user. The status display means 145 displays the status of the unmanned aerial vehicle 120 (moving, landing status, grain extraction in progress, extraction completed, returning, current flight position, etc.) and the status of the combine 1 (current traveling position, yield information, etc.) on the mobile terminal 140 in response to a status display operation by the user.

In this embodiment, configured as described above, the combine harvester 1 is equipped with a grain tank 4 for storing harvested grain. It is also equipped with a takeoff and landing section 20, located above the grain tank 4, from which an unmanned aerial vehicle 120 can take off and land, and a grain transfer section 40 that can transfer the grain in the grain tank 4 to the unmanned aerial vehicle 120. Therefore, the unmanned aerial vehicle 120 can be used to obtain the grain in the grain tank 4 even from a remote location.

The grain transfer unit 40 is also provided on top of the grain tank 4 and includes a temporary storage unit 41 that temporarily stores grain supplied to the grain tank 4, and a suction port 42 that enables the unmanned aerial vehicle 120 that has landed on the takeoff and landing unit 20 to suck up the grain in the temporary storage unit 41, thereby facilitating the transfer of grain from the grain tank 4 to the unmanned aerial vehicle 120.

In addition, the temporary storage section 41 is equipped with a grain intake port 43, and a portion of the grain supplied to the grain tank 4 is stored in the temporary storage section 41 via the grain intake port 43, thereby simplifying the configuration for storing grain in the temporary storage section 41.

Next, another embodiment of the present invention will be described with reference to Figures 7 to 10. However, only differences from the first embodiment will be described, and the same reference numerals will be used for components common to the first embodiment, and the description of the first embodiment may be used.

As shown in Figure 7, the second embodiment differs from the first embodiment in that the temporary storage section 41B of the grain transfer section 40B is detachable from the grain tank 4B, and in that it is equipped with a connecting section 47 that connects the unmanned aerial vehicle 120B that has landed on the takeoff and landing section 20B to the temporary storage section 41B. Furthermore, in the second embodiment, by allowing the unmanned aerial vehicle 120B to take off with the temporary storage section 41B connected, a grain suction means on the unmanned aerial vehicle 120B side is not required.

Specifically, the grain tank 4B in the second embodiment has an opening 48 in the ceiling for inserting and removing the temporary storage section 41B, and the opening 48 can be opened and closed by a shutter 49.

The temporary storage unit 41B has a grain intake port 43 similar to that of the first embodiment, a storage unit main body 50 that can be inserted into the grain tank 4 from above through the opening 48, and a flange portion 50a that extends outward from the upper end of the storage unit main body 49 and abuts against the upper surface of the grain tank 4B to prevent the storage unit main body 49 from falling.

The connecting portion 47 is provided, for example, on the temporary storage portion 41B side and the unmanned aerial vehicle 120B side and is composed of hooks 47a and 47b that can be engaged with and disengaged from each other, but it may also be composed of an electromagnet.

According to this second embodiment, after temporarily storing the grains in the temporary storage section 41B (see Figure 7(a)), the unmanned aerial vehicle 120B that has landed at the takeoff and landing section 20B is simply connected to the temporary storage section 41B (see Figure 7(b)), which completes the transfer of the grains from the grain tank 4B to the unmanned aerial vehicle 120B, allowing the unmanned aerial vehicle 120B to take off quickly (see Figure 7(c)).

As shown in Figure 8, the third embodiment differs from the first embodiment in that the unmanned aerial vehicle 120C is equipped with a container 130 capable of storing grain, the grain transfer unit 4C is equipped with a container inlet 51 that allows the container 130 to enter the grain tank 4C, and a portion of the grain supplied to the grain tank 4C is stored in the container 130. According to this third embodiment, it is not necessary to provide temporary storage units 41, 41B on the grain tank 4C side or to provide a grain suction means on the unmanned aerial vehicle 120C side.

Specifically, the grain tank 4C of the third embodiment has a container inlet 51 in the ceiling portion for inserting the container 130, and the container inlet 51 can be opened and closed by a shutter 52.

When the container 130 enters the grain tank 4C through the container inlet 51, it has a grain intake port 130a on one side opposite the grain inlet 10a of the grain lifting and conveying device 10. This allows the container 130 to store some of the grain supplied from the grain lifting and conveying device 10 into the grain tank 4C through the grain intake port 130a.

According to this third embodiment, when the unmanned aerial vehicle 120C lands on the takeoff and landing section 20C above the grain tank 4C, the shutter 52 is opened to open the container entrance 51 (see Figure 8(a)), and the container 130 of the unmanned aerial vehicle 120C enters the grain tank 4C through the container entrance 51 (Figure 8(b)). If harvesting operations are continued in this state, some of the grain supplied to the grain tank 4C from the grain lifting and conveying device 10 is stored in the container 130 through the grain intake opening 130a. Once a sufficient amount of grain has been stored in the container 130 (a predetermined time has passed since landing), the unmanned aerial vehicle 120C takes off and returns to base.

As shown in Figure 9, the fourth embodiment is similar to the second embodiment in that the temporary storage section 41D of the grain transfer section 40D is detachable from the grain tank 4D and includes a connecting section 47 that connects the unmanned aerial vehicle 120D that has landed on the takeoff and landing section 20D to the temporary storage section 41D. However, it differs from the second embodiment in that it includes a transfer section that transfers a portion of the grain accumulated in the grain tank 4D to the temporary storage section 41D. According to this fourth embodiment, grain can be reliably stored in the temporary storage section 41D.

The transfer unit is, for example, a suction device 53 incorporated into the temporary storage unit 41D, which sucks up some of the grain accumulated in the grain tank 4D to the temporary storage unit 41D via a suction tube 53a. The suction device 53 also has the function of winding up and unwinding the suction tube 53a.

In this fourth embodiment, after some of the grain accumulated in the grain tank 4D is sucked up to the temporary storage section 41D via the suction tube 53a (see Figure 9(a)), the suction tube 53a is rolled up (see Figure 9(b)). After that, the unmanned aerial vehicle 120D that has landed on the takeoff and landing section 20D is simply connected to the temporary storage section 41D (see Figure 9(c)), completing the transfer of grain from the grain tank 4D to the unmanned aerial vehicle 120D, allowing the unmanned aerial vehicle 120D to quickly take off (see Figure 9(d)).

As shown in Figure 10, the fifth embodiment is similar to the second and fourth embodiments in that the temporary storage section 41E of the grain transfer section 40E is detachable from the grain tank 4E and is provided with a connecting section 47 that connects the unmanned aerial vehicle 120E that has landed on the takeoff and landing section 20E to the temporary storage section 41E. However, it differs from the second and fourth embodiments in that the temporary storage section 41E temporarily stores grain in the lower part of the grain tank 4E and is provided with a moving section that moves the temporary storage section 41E from the bottom to the top of the grain tank 4E. Even with this fifth embodiment, grain can be reliably stored in the temporary storage section 41E.

The moving part is, for example, a hoisting device 54 that suspends the temporary storage part 41E via a wire 54a. When the temporary storage part 41E is pulled up from the bottom to the top of the grain tank 4E by the wire hoisting operation, the hoisting device 54 and the temporary storage part 41E become integrated.

According to the fifth embodiment, the temporary storage section 41E is positioned below the grain tank 4E, and after a portion of the grain supplied to the grain tank 4E is stored in the temporary storage section 41E (see FIG. 10(a)), the temporary storage section 41E is pulled up by the hoisting device 54 and integrated with the hoisting device 54 (see FIG. 10(b)). After that, the unmanned aerial vehicle 120E that has landed on the takeoff and landing section 20E is simply connected to the temporary storage section 41E (see FIG. 10(c)), completing the transfer of grain from the grain tank 4E to the unmanned aerial vehicle 120E, allowing the unmanned aerial vehicle 120E to quickly take off (see FIG. 10(d)).
