Description

[Detailed description of the invention] Conventionally, a combine harvester equipped with a dividing rod extending from the outside of the grain culm pulling body on the uncut field side of the reaping device to the outside of the grain culm conveying device at the rear of the harvesting device has been used to remove fallen grain. When reaping and threshing the culm, the culm-top divider with the comb-top claw protruding forward is attached to the outside of the grain culm pulling body on the uncut field side, and the culm is attached to the rear as shown in Figure 9. It was constructed so that the front part was pivoted by a certain pivot pin a and resiliently supported by a spring b, and the front part was moved laterally for pivot support. When the front part of the grass divider is moved inward and locked to the grass divider support frame, the support arm c of the grass divider is attached to the fixed support arm d protruding from the reaping frame as shown in the dotted line in Figure 9. Polymerizes as shown in
When adjusting the tilting of the grass dividing rod up and down to fit the pin e into any one of the plurality of adjustment holes f..., the grass dividing rod can be tilted and adjusted without difficulty.

However, when the comb-up splitter is attached as described above in order to reap and thresh the lodging grain culm, and the front part of the splitter is moved outward and locked, the support arm c of the splitter is moved as shown in Fig. 9. As shown by the solid line in , when spring b is compressed and only one side lifts up, if you forcibly adjust the tilt of the divider rod in this state, the divider rod or support arm will become bent or damaged, and the tilt adjustment operation will become extremely difficult. It was difficult.

In addition, long culms are particularly prone to lodging, but when trying to reap a lodging grain culm and transport it by a grain culm conveying device and supply it to a threshing device, it is necessary to move the rear part of the dividing rod outward as shown by the chain line in Figure 3. Since the grain culms cannot be made to protrude, there is a drawback that the grain culms in the uncut field fall into the grain culm conveying device.

The purpose of the present invention is to improve the above-mentioned drawbacks, and the present invention provides a method for transporting grain between a reaping device in which a plurality of grain culm lifting bodies are installed obliquely in the front part of the cutting blade and a threshing device in the rear. The device is interposed, and a combing-up weeding body with combing claws protruding forward is removably attached to the outside of the grain culm pulling body on the uncut land side, and the uncut part of the reaping device and the grain culm conveying device is removed. The front part of the grass cutting rod is supported on the outside of the mowed field so that it can be rotated and moved laterally, and the support rod that protrudes from the rear side can be adjusted up and down and attached to the support plate fixed to the machine frame. In the attached combine harvester, an auxiliary support plate protruding outward from the support plate is removably attached to the support plate, and the support rod of the weeding rod is attached to the auxiliary support plate in a vertically adjustable and detachable manner. It is characterized by being worn.
