0002

[Conventional technology]

Conventionally, in the combine harvester mentioned above, the rake teeth are in the shape of a spiral plate, which causes the rotation of the handling barrel. Due to the large amount of air generated by the cylindrical body and the communication between the tubular body and the handling As a result, more wind was leaking from the handling room into the cylindrical body.

0003

[Problem that the idea aims to solve]

Traditionally, during harvesting, especially when soybeans are being harvested, dust generated from the grain culms has been The amount of dust increases, and the volume of the transported grain culm is relatively small, causing dust inside the cylindrical body. Since dust flows easily, the dust generated inside the cylindrical body is caused by the inflow of air from the handling room. It was easy for grain to leak out from the grain receiving opening of the cylindrical body. The purpose of this invention is to prevent clogging of grain culms during harvesting of rice, wheat, etc. However, it is easy to avoid dust leakage from the handling room and from the wind. The purpose is to do so.

0004

[Means to solve the problem]

In order to achieve the purpose of the whole culm input type combine harvester of this invention, In the above-mentioned device, the guide surface for the wind generated by the rotation of the handling cylinder is along or almost along the outer periphery of the front end of the handling cylinder and close to the scraping teeth; The front end has an arc-shaped guide surface that guides the generated wind along the circumferential direction of the handling cylinder. and provided between the lower portion at the front end and the body wall of the threshing device. There is. Its action and effect are as follows.

[0005]

[Effect]

The wind generated as the handling cylinder rotates is directed to the front end of the handling cylinder in the circumferential direction by the guide surface. If the wind is guided along the side, the generated wind will be drawn into the end of the working circumference of the handling cylinder, and will flow from the handling chamber to the front. It becomes difficult for the liquid to come out to the side, making it difficult for it to flow into the cylindrical body. Therefore, rice, wheat, etc. During harvesting, the reaped grain culm enters smoothly and flows to prevent clogging. As a result, when harvesting soybeans, etc., the volume of the transported grain culm is reduced. The grain receiving opening and cross-sectional area of the cylindrical body are large compared to the size of the cylindrical body. Even if dust flows easily, and the amount of dust generated inside the cylindrical body increases. Also, the dust flow caused by the wind generated in the handling room is less likely to occur, and the dust can also flow outside the cylindrical body. It becomes difficult to come out.

[0006]

[Effect of the idea]

The grain culm receiving opening and cross-sectional area of the cylindrical body are increased to prevent grain culm clogging. While it is possible to harvest rice, wheat, etc., when harvesting soybeans, etc. Dust generated inside the cylindrical body is difficult to leak outside, allowing work to be done while preventing environmental deterioration. Now I can do it.
