[Problems to be solved by the device]

 In this type and form, the unprocessed material sent from the handling chamber is subjected to threshing treatment in the processing chamber, and the dust discharged to the outside of the machine is discharged at the end of the sorting chamber. Since it is supplied to the intermediate position of a long Straw rack that protrudes to the outside of the selection room for sorting processing, the transport distance of dust discharged by the Straw rack discharged from the end of the Straw rack to the outside of the machine becomes long. Therefore, the amount of dust generated when rice with morning dew is harvested (generally called wet handling) increases as the amount increases, making it difficult to transport. Therefore, there was a problem that caused poor selection. In addition, depending on the vertical arrangement relationship between the handling cylinder and the processing cylinder, there are cases where the dust reaching the end of the handling cylinder chamber 1 cannot be smoothly sent to the processing cylinder chamber side through the dust outlet.

[0004]

[Means for Solving the Problems]

 The present invention provides a threshing treatment device that improves the sorting performance, and has taken the following technical means. That is, from the lower side of the handling barrel chamber 1 where the handling barrel 2 is mounted on the interior shaft to the rear side in the handling barrel axial direction, the terminal end is located in the sorting chamber below the handling barrel chamber 1 and close to the part communicating with the outside of the machine. In addition, the rocking sorting shelf 13 is provided, and the processing cylinder chamber 9 in which the processing cylinder 10 that receives the dust discharged from the dust discharge port 5 on the terminal side of the handling cylinder chamber 1 and processes it while sending it backward is mounted on the interior shaft. , Are arranged side by side in the handling barrel chamber 1 and extend rearward from the end of the handling barrel chamber to a position above the end portion of the rocking / sorting shelves 13, and the leaked substances from the receiving net 11 of the processing barrel chamber 9 are The oscillating sorting rack 13 is supplied to the sorting chamber for sorting, and the dust is dropped from the dust outlet 12 opened above the end of the oscillating sorting rack at the end side of the processing chamber 9 to the sorting chamber for sorting. The dust discharged to the end of the swing selection shelf 13 is discharged to the outside of the machine together with the dust discharged from the end of the swing selection shelf 13. In the side view of the handling cylinder chamber 1, the handling cylinder 2 and the processing cylinder 10 are moved up and down so that the virtual extension line of the net end facing the dust outlet 5 is located near the processing cylinder axis 24. The threshing treatment device is characterized by being arranged in the direction.

[0005]

[Action]

 The dust that has reached the terminal end of the handling barrel chamber 1 is sent from the handling barrel chamber 1 into the processing barrel chamber 9 along the receiving net 3 facing the dust outlet 5 in the axial direction of the processing barrel axis of the processing barrel 10. Then, the grains are mixed with the dust by the processing cylinder 10 while being sent backward, and the grains mixed in the dust during this time leak from the processing cylinder chamber 9 and are sorted by the swing sorting shelf 13 below. . It did not leak from the processing chamber 9 and fell from the dust exit 12 on the terminal side of the processing chamber 9 into the sorting chamber for sorting, and the end fell to the end of the swinging sorting shelf 13 located in the sorting chamber. The dust is discharged to the outside of the machine together with the dust from the end portion of the shaking and sorting shelf 13.

[0006]

【effect】

 Since the dust can be smoothly sent from the handling chamber to the processing chamber through the dust removal port 5 by the receiving net 3, there is no stagnation of the dust in the handling chamber and the threshing treatment capability can be improved. Since the distance from the position of the rocking sorting shelf 13 where the dust falls to the discharge position to the outside of the machine becomes short, the dust does not leak from the processing chamber 9 and the dust on the terminal side of the processing chamber 9 is discharged. Even if the dust that has fallen from the mouth 12 to the end of the rocking sorting rack 13 is moist and heavy dust, it is quickly discharged out of the machine together with the dust at the end of the rocking sorting rack 13. Therefore, it is possible to reduce the load of rocking sorting and wind sorting, enhance the sorting processing capacity, and expect good sorting action.

Further, since the end of the rocking sorting shelf 13 is located in the sorting chamber below the handling barrel chamber 1 in the vicinity of the portion communicating with the outside of the machine, the dust can be discharged smoothly. Also, the dust can be sorted by the rocking sorting rack to enhance the in-machine collection of grains.
