Japanese Patent Laid-Open No. 7-274663 ([0012] stage, FIGS. 1 and 2)

  In a full-throwing-type threshing machine, the entire harvested culm from the stock source to the tip is supplied to the handling room and threshing is processed. The amount of scraps mixed in the second processed material conveyed from the section also increases. If the second processed material is returned to the oscillating sorter with a large amount of mixed waste, etc., the sorting capability and sorting accuracy of the oscillating sorter are likely to be lowered.

  By adopting the technique disclosed in Patent Document 2, if the processed material from the transport device is subjected to the sorting action and then supplied to the oscillating sorting device, the cost is increased and complicated due to the auxiliary tang The structure tends to be different.

  An object of the present invention is to provide a full-throwing type threshing machine that can obtain a low-cost and simple structure that can efficiently and accurately perform sorting by an oscillating sorter regardless of the reduction of the second processed product. It is to provide.

In this 1st invention, it is provided with the threshing part which throws out the threshing process by the handling cylinder which throws the whole harvested cereal rice cake into the handling room, and rotates, In the all-throwing-type threshing machine equipped with a sorting section for sorting by the sorting wind supplied from the front end of the threshing machine to the rear of the threshing machine,
Between the upper end of the receiving net of the handling room and the top plate, a partition wall is provided for partitioning the handling room and the threshing machine body space, and the treatment passage is defined by the partition wall and the threshing machine body side wall. A discharge port that is formed in the threshing machine body in communication with the sorting chamber of the sorting unit and communicates with the threshing machine body of the conveying device that returns the second processed material from the sorting unit to the swing sorting device, It faces the passage.

  That is, since the partition wall and the threshing machine body side wall are formed in a state where the treatment passage is communicated with the sorting chamber, a part of the sorting air flowing out from the sorting chamber flows into the treatment passage and this treatment is performed. When the material passage flows in the rear direction of the threshing machine body and the processed material from the sorting unit is discharged into the threshing machine body from the discharge port of the transport device, it is subjected to the sorting action by the sorting wind flowing into the processed material passage from the sorting chamber.
