[Technical field]

[0001] The present invention relates to a combine harvester in which the traveling device of the combine harvester is driven by an engine and functional devices such as a threshing device are driven by an electric motor, or a combine harvester in which all functional devices including the traveling device are driven by an electric motor. [Background technology]

[0002] As described in JP 2020-198818 A, a combine harvester is configured with a running vehicle body that travels on a crawler running device, and is equipped with functional devices such as a harvesting device that harvests stalks growing in the field, a transport device that sends the harvested stalks up to a threshing device mounted on the body of the machine, a threshing and sorting device that threshes and sorts the grains from the harvested stalks, and a grain tank for storing the grains, and all of the functional devices such as the crawler running device, the harvesting device, and the threshing device are driven by the power of an engine mounted on the running vehicle body.

[0004] [Patent Document 1] JP 2020-198818 A [Patent Document 2] JP 2012-55223 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the first combine harvester, the engine mounted on the running body drives all of the harvesting equipment, the conveying equipment, the threshing and sorting equipment, and the grain discharge auger which discharges grain accumulated in the grain tank outside the machine. As a result, the engine is large and heavy with a high output, and the power transmission mechanism to the functional devices such as the harvesting equipment and the threshing and sorting equipment is complex.

[0006] In addition, because combine harvesters run on soft fields, as the harvesting process progresses, grains accumulate in the grain tank, making the grain tank side heavier and causing the vehicle body to tilt, or as fuel in the fuel tank gets low, the fuel tank side becomes lighter and causes the vehicle body to tilt. This causes the reaping height of the stalks to fluctuate, making harvesting difficult.

[0007] To provide a combine harvester equipped with a battery and having a functional device driven by an electric motor, capable of stably performing harvesting work by correcting the weight balance of a traveling body which fluctuates as harvesting work progresses by moving a heavy battery on the traveling body.

[0016] In the present invention, since the battery 48 is a heavy object, when the vehicle body inclination detection means detects the inclination of the machine frame 1, the battery mounting platform 10 on which the battery 48 is mounted is moved in an upward inclination direction to equalize the weight balance of the machine frame 1 and correct the inclination of the machine frame 1. This makes the combine harvester parallel to the field surface, uniforms the harvesting position of the stalks, and stabilizes the harvest. The first invention related to the present invention Since the battery 48 is a heavy object, when the vehicle body inclination detection means detects the inclination of the machine frame 1, the battery mounting platform 10 on which the battery 48 is mounted is moved in an upward inclination direction to even out the weight balance of the machine frame 1 and correct the inclination of the machine frame 1.

[0017] Second Invention Related to the Present Invention When grain accumulates in the grain tank 7, it becomes heavy and the machine frame 1 tilts, but when the vehicle body tilt detection means detects the tilt, the battery mounting platform 10 slides to a horizontal position away from the bottom of the grain tank 7 to improve the weight balance of the machine frame 1 and prevent the machine frame 1 from tilting.The combine harvester then cuts in parallel with the field surface, making the harvesting position of the stalks uniform and stabilizing the harvest.

[0018] The third invention related to the present invention When grains accumulate in the grain tank 7 and make it heavy, this can be determined by measuring the weight with the weight sensor 14, and the weight balance of the machine frame 1 can be corrected.

[0020] Fifth Invention Related to the Present Invention Since the fuel tank 15 becomes lighter due to a decrease in fuel, which can be detected by the remaining fuel on the fuel gauge, there is no need to provide a separate vehicle body inclination detection means 11, and the structure can be simplified.

[0021] The sixth invention related to the present invention If the vehicle body inclination detection means is a vehicle body inclination sensor 11, the inclination of the vehicle body frame 1 can be detected in all directions, forward, backward, left and right, and the sliding movement of the battery mounting platform 10 can be adjusted in the upward inclination direction.

[0022] The seventh invention related to the present invention During the harvesting of the stalks, the electricity generated by the contact of the stalks with the frictional power generation belt 49 during the transporting operation of the stalks is used to charge the battery 48 and drive the electric motor, so that the fuel consumption of the combine can be reduced and the harvesting operation can be continued for a long time.

[0025] As shown in Figures 1 to 3, the multi-purpose combine harvester has a traveling device 2 consisting of a pair of left and right crawlers that travel on the soil surface, provided below the machine frame 1, a pre-harvesting processing device 3 that harvests stalks in the field, provided in front of the machine frame 1, a thresher 4 that threshes and sorts the harvested stalks, provided on the rear left side of the pre-harvesting processing device 3, and a control unit 5 on which an operator sits, provided on the rear right side of the pre-harvesting processing device 3. A solar panel 60 is provided on the top plate of a cabin 59 surrounding the control unit 5, and electricity generated from sunlight is used to charge the battery 48. The solar panel may also be provided on the top plate of the grain tank 7 or the top plate of the feeder house 3D.

[0026] An engine room 6 housing an engine is provided below the control unit 5, a grain tank 7 for storing threshed and sorted grains is provided behind the control unit 5, and a discharge auger 8 for discharging the grains to the outside is provided behind the grain tank 7. Driving force is transmitted from the engine to the traveling device 2, the threshing device 4, and the discharge auger 8 via a power transmission mechanism.

[0027] The pre-harvesting treatment device 3 is composed of a transport device 3A that transports the culms in the field to the rear while standing them up, a cutting blade device 3B that cuts the base of the culms transported to the lower rear side of the transport device 3A, an auger device 3C that gathers the culms transported to the rear side of the transport device 3A to the left side, and a feeder house 3D that transports the gathered culms to the threshing device 4. The pre-harvesting treatment device 3 is driven by power transmitted from an electric motor 46 via a power transmission mechanism.

[0028] FIG. 4 shows a combine harvester in which the pre-harvest processing device 3 is motorized, and the traveling device 2 and threshing device 4 are driven and transmitted power from the engine via a power transmission mechanism consisting of a drive shaft and a transmission belt.
