  It is an object of the present invention to provide a threshing machine that has a simple configuration and that can easily adjust the blowing direction.

  In order to solve the above-mentioned problems, the present invention takes the following technical means.

  That is, the invention described in claim 1 is provided with a rough sorting section that performs rough sorting while swinging and transporting the sorting processed product under the handling chamber (9) for threshing the harvested cereal meal. While swinging and transferring the sorted processed product, the grain is allowed to leak into the first product recovery unit (25b) and the second product is dropped onto the second product recovery unit (26c) arranged on the lower side in the transfer direction. An oscillating sorting device (14) is provided, and a blower drum plate (19) formed in a cylindrical shape having an opening at the rear end at a lower front portion of the oscillating sorting device (14), and the blower drum plate (19) The upper ventilation guide plate (20a) and the lower ventilation guide plate (20b) connected to the upper and lower sides of the rear end opening portion form the sorting air chamber (21), and the inside of the sorting air chamber (21) The rotary airflow guide plate (20a) and the lower airflow guide plate (20b) are rotatably supported by a tang blade (22) that generates the sorting air. A wind split (23) for dividing the sorting wind into a main sorting wind (A) and an auxiliary sorting wind (B) is provided, and the wind direction is provided at the rear end (C) of the upper draft guide plate (20a). The threshing machine is characterized in that the rear end portion of the adjustment plate (24) is attached so as to be rotatable up and down.

  Upon receiving the supply of the harvested cereal meal into the handling room (9) of the threshing machine (1), the threshing is carried out in the handling room (9), and while being oscillated and transferred to the lower side of the handling room (9), While the coarse sorting unit for sorting and the sorting processed material leaked from the coarse sorting unit are rocked and transferred, the grain is sorted and leaked to the first product recovery unit (25b), and the second product is transferred.
