And a pre-combining harvesting processing device, characterized in that it is configured to be faster . First, the configuration will be described. Traveling car body 3
Has a configuration in which a traveling frame 5 is provided with a crawler 6 so as to be able to travel in wet fields, and is equipped with a threshing device 1. And
As is conventionally known, the threshing apparatus 1 includes a handling room and a sorting room, and is configured to thresh and sort the supplied harvested culm. [0007] Reference numeral 7 denotes a Glen tank, which is a rice processing device 2
And is configured to be able to store the grains after threshing and sorting. The pre-cutting device 8 includes a weeding rod 10 supported on the cutting elevating support frame 9,
The cereal stem raising device 11, the mowing device 4, and the cereal stem transport device 12 are integrally framed. The mowing elevating and lowering support frame 9 is provided so as to be rotatably supported at its rear portion on a support 13 of the traveling vehicle body 3, and is configured to be able to freely move up and down by a hydraulic cylinder 14 provided at an intermediate portion. Is provided with a roller 15 for slidingly guiding the pre-cutting device 8. The pre-cutting device 8 comprises a weeding support rod having a weeding rod 10 attached at its tip to a transmission case 16 disposed laterally at the rear and an L-shaped member 17 also disposed laterally at the front. 19, 1
The reaper 4 is located between the two weed support rods 19, 19 "at a low position in front of the transmission case 16 at a lower position. It is constructed so that it can be hung and attached, and the lower part of the cereal stem in the field is cut off. And the pre-cutting device 8
An L-shaped member 17 at the rear of the mowing device 4 is supported by rollers 15 of the mowing elevating support frame 9 so as to freely move left and right, and a slide ring 20 provided at the rear portion is provided on the mowing elevating support frame 9. 21
Is slidably fitted to In this manner, the transmission case 16 is configured to be slidable in the left-right direction by the sliding guide action of the receiving rod 21 and the sliding ring 20. The cereal stem raising device 11 has a raising lug 23, the start end of which is inclined downward with the end portion located rearward and upward, and is supported by a support tube 24 protruding from the transmission case 16 so as to be capable of transmission. ing. The left and right driving device 25 is configured such that a screw rod 26 axially mounted along the receiving rod 21 of the mowing elevating and lowering supporting frame 9 can be rotated in forward and reverse directions by a motor 27. . As described above, the sliding ring 20 is slidably fitted to the receiving rod 21 and screwed to the screw rod 26 as well. The telescopic shaft 28 is connected to the universal joints 29, 29 'at both ends, and the base end of the telescopic shaft 28
Is connected to the transmission portion of the support base 13 and the other is the transmission case 16.
It is configured so as to be able to transmit to the motor. Next, the controller device 30 is provided with an inclination sensor 31 on the traveling vehicle body 3, and receives a signal when the inclination sensor 31 detects the inclination of the traveling vehicle body 3, and compares the degree of inclination with a reference value. When it is large, a driving output signal is sent to the motor 27. Then, in this case, when the traveling vehicle body 3 tilts to the left, the controller device 30 sends a forward rotation output signal to the motor 27 and slides the reaping pre-processing device 8 to the right, so that the traveling vehicle body 3 moves to the right. When it is tilted in the reverse direction, a reverse output signal is issued to the motor 27 to slide the mowing pre-processing device 8 to the left. When the motor 27 is turned on and off by a manual switch, the screw rod 26 is driven earlier if the operation time is longer than the reference time. Next, the operation will be described. First, in the pre-cutting device 8, the cutting device 4, the grain stalk raising device 11, and the grain stalk transport device 12 are driven by the rotational power transmitted into the transmission case 16 via the telescopic shaft 28. When the traveling body 3 is moved forward by driving the crawler 6, the culm in the field is vegetated by the weeding rod 10 at the front, and then reaches the beginning of the cereal culling raising device 11 to be raised. It is caused by the lug 23 to be in an upright state. Then, the seeds of the cereals are cut off by the reaping device 4, conveyed to the upper rear portion by the cereal culm conveying device 12, and supplied to the threshing device 1. Then, the grains that have been threshed and sorted are conveyed by the first fryer and are sequentially stored in the Glen tank 7. In this way, the combine
The hull moves forward while performing the cutting and threshing operation, and the grains are sequentially stored in the Glen tank 7, and the weight of the grains increases. Then, the inclination sensor 31 detects that the traveling vehicle body 3 is inclined as the grain weight increases, and transmits a signal to the controller device 30. As described above, the transmitted signal is compared with the reference value in the controller 30 and outputs an output signal to the motor 27 only when it exceeds the reference value to drive and rotate. The cutting pretreatment device 8 is slid in the opposite direction (opposite to the Glen tank 7) via the screw rod 26 and the sliding ring 20. In this way, the traveling vehicle body 3 moves the center of gravity by moving the direction of correcting the inclination and moves the center of gravity to return to a horizontal or nearly horizontal state by detecting the degree of inclination of the inclination sensor 31. Accordingly, the inclination of the traveling vehicle body 3 is corrected by correcting the weight balance, the straightness is secured, and the work can be continued smoothly. The mowing pre-processing device 8 drives the motor 27 by operating a switch (not shown) when mowing near the ridge or when the crawler 6 is separated from the adjacent grain culm row. Then, the screw rod 26 is rotationally driven and is forcibly guided to one side via the sliding ring 20 and moves. During such movement, the pre-cutting device 8
The L-shaped member 17 is guided by the roller 15 and moves in the left-right direction, and the telescopic shaft 28 is adapted to move by the universal joints 29 and 29 'at both ends to continue transmission. Since the mowing pre-processing device 8 can rotate the screw rod 26 quickly by continuously operating the switch, the mowing pre-processing device 8 can slide quickly. [0018] The present invention described above [effects of the invention], in combine formed by providing a pre-processing device cutting the front lower position of the vehicle body equipped with a threshing device and rice processing apparatus, the cutting front A processing device is provided so as to freely move in the left-right direction with respect to the traveling vehicle body, and the pre-cutting device is moved left and right.
