Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for returning No. 2 recovered from the threshed material that is threshed in the handling chamber and sorted by the sorting section below the handling chamber into the handling chamber. , relates to an improvement of the No. 2 reducing device in a threshing device.

A threshing device that returns the No. 2 collected in the sorting section to the handling room by the No. 2 return machine. For example, it is mounted on the body of a combine harvester as a threshing section, and immediately threshes the husk harvested in the reaping section. When a large amount of No. 2 is produced, such as when threshing wet culms, the load in the handling room may be excessive and the threshing process in the handling room may be impaired. In addition, even when the grain rods to be threshed have good properties and the amount of No. 2 grains generated is small, the No. 2 grains to be collected include single grains that do not require reprocessing in the handling room. Also, since grains that are close to single grains are mixed in, there are problems in that unnecessary impact is applied to the grains, increasing the number of damaged grains, and putting an unnecessary burden on the handling room.

An object of the present invention is to solve these problems.

In order to achieve this purpose, the second reducing device in the threshing device according to the present invention has a second reducing port provided in the handling chamber in communication with the discharge tube of the second reducing machine, on the culm exit side of the handling chamber. At the upper part of the handling chamber, insert the shell culm in the handling chamber at a position that is removed from the outer periphery of the receiving net when viewed from the axial direction of the handling chamber. In front of the No. 2 reducing port in the blowing direction of the No. A guide plate 1 that flows down to the inner circumferential side of the receiving net in the chamber is installed with a gap between it and the No. 2 reducing port, and the lower part of the gap is seen from the axial direction of the receiving net. The feature is that a second flow passage is formed on the outer peripheral side, which communicates with the sorting section provided below the handling chamber.

Next, an embodiment will be described in detail according to the drawings. In FIG.
