[Detailed description of the invention] The present invention includes a swinging sorting device disposed at the bottom of the threshing section, a grain collecting device at the bottom of the swinging sorting device, and a second grain from the collecting device. The present invention relates to a conventional combine harvester equipped with a screw conveyor for lifting and returning grains to the threshing section.

The above-mentioned combine harvester is configured to re-thresh and refine secondary grains such as grains with stems, but when the target for threshing is rice, it depends on the degree of dryness and variety of the rice. Depending on the characteristics of the grains, re-threshing the second grain may result in damaged grains such as shelled grains or broken grains, and when harvesting wheat, regardless of its characteristics, This method has the drawback that damaged grains are easily produced and the recovery efficiency of the first grains is low.

The present invention has been developed in view of these points, and aims to minimize the occurrence of damaged grains through appropriate reprocessing according to the properties of the second grain and the harvest target, thereby increasing the recovery efficiency of the first grain. A lower opening is formed above the swinging sorting device in the oblique conveyor tube in which the screw of the screw conveyor is installed, and the lower opening is formed in the lower opening. A cylinder formed with corresponding openings is provided on the conveyor cylinder so as to be freely switchable by rotation between a first state in which the lower opening is closed and a second state in which both openings are communicated, and the switching operation tool is operated. a cylindrical chute which is provided near the section, enables the second product to be switched between the threshing section and the swing sorting device in the driving section, and returns the second product onto the swing sorter in the second state; It is characterized by being placed.

In other words, even if it is a second product, such as wheat or rice, depending on the variety, degree of drying, etc., the action of massaging by the screw conveyor for reducing the second product may be affected. Furthermore, it was discovered through experiments that by applying the shaking action of a shaking sorter, it was possible to finely refine the second grain while suppressing the generation of damaged grains. Therefore, by making a simple modification to the screw conveyor, it is possible to selectively return the second material to the threshing section and the swinging sorting device by switching the operation tool of the driving section. If the second grain is rice with many branches and stems, it is returned to the threshing section, and if the second grain is a problem with damaged grains, it is returned to the oscillating sorting device. It has become possible to suppress the generation of damaged grains as much as possible, and in turn, it has been possible to achieve a significant improvement in the recovery efficiency of the first grains.
