DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing the accumulation of straw waste and the like generated during harvesting by a combine on an airframe.

[0002]

2. Description of the Related Art Conventionally, a mowing section has been arranged on one side of a combine, a threshing section has been arranged behind the combine section, a Glen tank has been arranged on opposite sides of the combiner, and an operating section has been arranged in front of the harvesting section. The stem side of the culm harvested in step 2 is handed over so as to be clamped by the feed chain, and the spike side of the culm is conveyed backward while guiding it into the threshing unit, threshed, and the sorted first item is stored in the Glen tank. Then, the waste was thrown into the waste processing apparatus at the rear of the machine, cut, or bound and discharged to the rear of the machine.

[0003] A rod-shaped side divider is arranged outside the feed chain of the machine over the entire length of the machine, and guides the uncut culm to the outside of the machine during the harvesting operation. It was not to be pulled into the traveling device.

Further, a suction fan is provided horizontally at the rear of the threshing unit, and a discharge port is provided to project rearward and downward from a side of the suction fan on the feed chain side. In addition, a power transmission unit including a pulley, a belt, and the like that transmits power to each device of the threshing unit is disposed on a side of the body on the feed chain side, and a side cover is detachably provided outside the power transmission unit. Had been. The discharge port extends above and behind the side cover, and the rear end of the side cover is bent inward to separate the power transmission unit and the discharge port. Even if the waste was discharged outside through the discharge port, the waste was prevented from entering the power transmission unit from the rear.

[0005] In addition, an input port is opened in the straw processing device at the rear of the machine body. The input port is opened to take in the thresh after threshing into the inside for cutting, and the upper input port is closed. And transported backward as it is, tied by a tying device, or discharged to the field at regular intervals.

[0006]

However, in the prior art, the support member at the rear of the side divider is
It is fixed to the rear end of the fuselage frame, the rear end of the side divider and the rear of the fuselage substantially match, and the undivided grain culm is guided by the side divider with the progress of the fuselage in the direction away from the fuselage. In such an area, straw waste and the like are accumulated, and the operation of removing the accumulated straw waste is a troublesome operation for the operator.

Further, the rear end of the side cover is bent inward to partition between the outlet and the outlet, and the lower portion of the side cover is bent inward to prevent a gap from opening at the lower end. However, when the straw dust blown out from the discharge port is blown back from below, there is a problem that the power is lost due to slipping into the inside of the side cover through the gap, entangled with the internal pulley and belt, and the operator has a problem. It was necessary to perform maintenance work to clean the inside of the side cover.

In addition, a vertical discharge auger tube which forms a discharge auger for discharging paddy in the Glen tank is provided upright on a side of the straw processing device to which the straw is conveyed. A vertical discharge auger cylinder and a supporting column for supporting the straw processing device are erected at a position between the waste processing device and an electric circuit such as a swing motor, and are transported above the waste processing device. In some cases, the tip of the discharged waste was caught on a support pillar or the like, and the waste could not be smoothly put into the waste treatment device, or could not be successfully discharged to the field.

Further, the side and rear surfaces of the vertical conveyor cylinder of the discharge auger are covered with an L-shaped cover in plan view, and the cover is opened to the side to perform maintenance on the vertical conveyor cylinder and the turning motor. However, it is necessary to rotate the cover to clean the straw debris accumulated around the lower part of the vertical conveyor cylinder, and the straw debris spreads and accumulates on the upper surface of the machine frame where the vertical conveyor cylinder is erected. Cleaning work was troublesome.

[0010]

According to the present invention, in order to solve such a problem, a reaper is disposed at a front portion of an airframe.
A threshing device is placed on the rear frame of the machine, and a combiner with a side divider protruding from the outside of the front of the reaper to the rear of the machine on the side where the threshing device is placed, and is pivotally connected to the rear end of the frame. And a pivoting portion projecting rearward from the body frame to pivotally connect the rear end of the side divider. Further, in the rear part of the threshing apparatus, a discharge port of a suction fan that suctions and discharges straw waste or dust after sorting is arranged, and in a combine in which a power transmission unit on the lower side of the threshing apparatus is covered with a side cover, A dustproof plate is provided at a lower rear portion inside the side cover, and the dustproof plate is arranged in an inclined manner. Further, in a combine provided with a Glen tank for storing the sorted paddy and a straw processing device disposed at the rear of the machine body, a guide plate is extended from the upper surface of the straw processing device to the Glen tank side. In addition, a vertical discharge auger cylinder of the discharge auger is arranged at the rear of the fuselage behind the Glen tank, the lower cover covering the lower part of the Glen tank extends to the side of the vertical discharge auger cylinder, and the vertical discharge auger is located above the rear of the lower cover. A rotating cover that covers the side and rear of the auger cylinder is rotatably disposed, a rear cover is disposed below the left and right sides of the rear of the rotating cover, and the lower portion of the rear cover is a vertical discharge auger cylinder. It is an inclined shape extending to the side.
