[Prior Art] A thresher has a configuration in which a plurality of screw sorting mechanisms are installed in parallel below the handling chamber, and the materials to be sorted that fall from the receiving net in the handling chamber are sorted while being agitated and transferred along the axial direction of the handling barrel. Already known. This type of model only has the function of sorting out what leaks from the receiving net in the handling room, and is discharged from the dust drop port at the end of the handling room or the dust drop port in the dust treatment barrel connected to the handling room. However, there was little expectation that the processing capacity would be able to accept waste materials containing a large amount of straw waste and sufficiently process and sort them. This problem could be solved by installing a dust processing and sorting mechanism consisting of a processing cylinder and a concave capable of exhibiting sufficient processing capacity at the terminal end of the screw sorting mechanism. With this structure, it is not easy to attach and detach each part, and when a blockage occurs, it takes time and effort to clear the blockage and clean it, resulting in a decrease in work efficiency.
