Field of the Invention The present invention relates to a weeding section equipped with a harvesting machine such as a combine harvester or a binder, and more specifically, to a portion arranged to separate a harvested culm from an uncut side culm. The present invention relates to a weeding part of a reaping harvester in which a rod-shaped rotating swarding body having a peripheral surface with a radius of gyration different depending on the circumferential direction is provided so as to be freely rotatable and tilted backward.

Description of the Related Art Conventionally, as a rotary type weeding means, as shown in, for example, Japanese Unexamined Patent Publication (Kokai) No. 3-65117, there has been known one used in a strawberries harvester. In this case, a drive device for the rotating grass is formed so that the rotating grass is continuously rotated in a constant direction at all times, and vibration is imparted to the rice culm due to the rotation of the peripheral surface having a different radius of rotation depending on the circumferential direction. It was designed to loosen the entanglement of the cultivars and to cultivate the culms by the scooping action of the rotating buds as the aircraft progresses.

を効果的に抑制できるようにする点にある。However, the following problems are expected to occur when the rotary type weeding means is used as a combine or a binder for harvesting rice. In other words, in the case of straw grass, the stem culm is relatively hard and difficult to wrap around, so there is no support even if it is continuously rotated in a certain direction, but when harvesting flexible rice that has fallen, it is always continuous in a certain direction. It is easy for culms and weeds to wind around the rotating rotating subdivided body, which causes a decrease in the weeding function due to plant winding, and it takes time and effort to remove the wrapped plants, and the aspects of maintenance and management of the rotating subdivided body are There was room for improvement. An object of the present invention is to make it possible to effectively suppress plant wrapping around a rotating plant body.

されるように形成したことにある。A feature of the present invention is that the cutting surface is arranged in the cutting section to separate the cut culms and the uncut side culms, and a peripheral surface having a different rotation radius in the circumferential direction is used. In a reaping and harvesting machine in which the rod-shaped rotating grass body that is provided is freely drivable and is tilted backward, the drive device for the rotating grass body is formed so that the rotating grass body can reciprocally rotate within an angle range of one rotation or less. There is something I did.

草機能低下及び作業中断を十分に防止できる。In other words, according to the cross-sectional shape of the peripheral surface whose radius of gyration differs depending on the circumferential direction, the reciprocating rotation of the rotating grass body causes the rotation of the peripheral surface to impart sufficient vibration to disentangle the culms. By setting the angle range appropriately, while maintaining a good weeding function by the rotating grass body, reciprocating rotation of the rotating grass body within an angle range within one rotation effectively causes plant wrapping around the rotating grass body. It can be suppressed, and it is possible to sufficiently prevent the decline in the function of the grass and the work interruption due to the winding of plants.
