There is.

In order to provide the processing chamber B, it is constructed to be shorter than the handling chamber A, and is placed so as to be offset to the starting end of the handling chamber, so that the supplied second material is transferred from the starting end of the handling chamber A to the terminal end using the processing cylinder 12. The structure is configured so that the grains are processed while being transferred along the opposite direction, and furthermore, the receiving net 13 for dropping and supplying the grains to the sorting device and the residual processing material at the terminal end thereof are handled at a point closer to the starting end than the discharge port 4. Provided with a communication port 14 for returning to the chamber A portion,
Properly processed grains are quickly dropped and fed to the sorting device through a receiving net 13, and residual processed material that has not fallen through the receiving net 13 is transferred to a handling cylinder 1 which has a larger diameter than the processing cylinder 12 and has a powerful stirring function. After being processed, the material is dropped and supplied to a sorting device. Further, a drop passage C to the sorting device is formed near the right side of the terminal end of the treatment chamber A and near the end of the processing chamber B, and the discharge ports 11a of the throwers 10 and 11 are connected to the drop passage. C is located on the opposite side of the processing chamber B in communication with the upper part of the processing chamber B, and the straw waste in the second material, which is likely to stall, is placed in the falling passage C.
It is configured to be discharged to the sorting device through the filter. In short, by preventing the supply of straw waste into the processing chamber B, the
It is designed to allow good processing of items.

In addition, in order to equip the processing chamber B with the communication port 14,
Various forms are possible. That is,
In FIG. 5, a sliding plate 15 is provided which can be slid in the direction from the beginning to the end of the treatment chamber, so that the opening amount of the communication port 14 along the direction from the beginning to the end of the treatment chamber can be changed and adjusted according to the amount of residual processing material. It is something. or,
FIG. 6 shows a system in which a processing object pressing wing 16 is provided at the end of the processing cylinder 12 to bounce the processing material into the handling chamber A through the communication port 14, so that the processing material can be sent into the processing chamber A accurately. It is something. Furthermore, FIG. 7 shows that when the communication port 14' is opened over the entire width of the processing chamber B along the start and end directions, if a large amount of processing material tends to accumulate in the processing chamber B, this can be prevented. is fed into the processing chamber A to avoid clogging in the processing chamber B.

In summary, the threshing device according to the present invention has the structure described above, and includes a receiving net 3 for dropping and supplying grains to the sorting device in the handling chamber A, and a residual processing material at the terminal end of the receiving net 3 to be sent to the sorting device. The processing chamber B is configured to be shorter than the handling chamber A, and the starting end of the handling chamber is offset to one side. A receiving net 13 for dropping and supplying the liquid to the sorting device
and a communication port 14 for returning the residual processed material to the treatment chamber A portion closer to the starting end than the discharge port 14, and an end of the treatment chamber B near the lateral side of the terminal end of the treatment chamber A. There is a drop path C to the sorting device near the section.
, and the discharge ports 11 of the throwers 10 and 11
A is located on the opposite side of the processing chamber B so as to communicate with the upper part of the falling passage C, and the following effects can be obtained.

B. Straw waste, which is likely to stall out of the second material supplied from the discharge ports 11a of the throwers 10 and 11 to the processing chamber B, can be discharged to the sorting device through the falling passage C. Disadvantages when straw waste is also supplied into the processing chamber B, that is, the straw waste may adversely affect the grain separation process in the processing chamber B, or the separated grains may be discharged from the processing chamber B. It is possible to improve the processing performance of the second item by avoiding the inconvenience of having an adverse effect on the process.

(b) In forming the falling passage C to obtain the above advantages, unnecessary straw waste is not supplied into the processing chamber B, so even if the processing chamber B is configured to be shorter than the handling chamber A, the second material can be processed as desired. Focusing on the ability to perform
Since the drop passage C is formed near the terminal side of the treatment chamber A and near the end of the processing chamber B, it is possible to prevent the apparatus from increasing in size due to the formation of the drop passage C.

Moreover, according to the present invention, while the grains that have been properly processed in the processing chamber B are quickly dropped and supplied to the sorting device through the receiving net 13, the residual processed material that has not fallen through the receiving net 13 is sent to the communication port 14. Through the outlet 4 provided in the handling room A
Since it is designed to feed first to the starting end of the cylinder and then fall from the handling chamber A to the sorting device, it is configured to have a smaller diameter than the handling cylinder 1 in order to reprocess the second item without damaging it. The residual processed material in the processing chamber B that could not be sufficiently agitated in the processing cylinder 12 is further agitated in the processing cylinder 1, which has a larger diameter than the processing cylinder 12 and has a powerful stirring function, and then is sorted. Capable of supplying drops to equipment. For example, compared to simply supplying the residual processing material in the processing chamber B by dropping it to the sorting device, as is commonly done in the past, the processing performance for the second material can be improved with the effects described in section (a) above. Further improvements can be made through collaboration.

D. Also, since the straw waste in the second material is removed in advance by the action of the falling passage C, the handling load can be reduced even though the structure is adopted in which the residue in the processing chamber B is returned to the handling chamber A. A threshing device that does not cause any increase in size and can be used more favorably as a whole has been obtained.
