Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is a thresher having a processing chamber on the side of the machine body, and opens and closes the processing chamber to clean the processing chamber or a sorting chamber below the threshing chamber. The present invention relates to a cleaning device in a thresher.

(B) Prior art Conventionally, a sorting chamber is provided at the rear of the handling chamber, and a processing chamber for treating the dust discharged by swinging is provided at the rear of the swing sorting body installed in the sorting chamber. A thresher in which the rear wall of the processing chamber can be opened and closed and the concave provided only on the lower surface of the processing cylinder can be inserted and removed is already known from Japanese Utility Model Laid-Open No. 60-125837.

(C) Problems to be solved by the invention Since the concave of the known threshing machine is arranged only on the lower surface of the processing cylinder, the leakage area is small and the leakage hole is extremely large. In the processing chamber receiving net aiming to process the grain-removing grain containing the first shell grains discharged from the side discharge port and drop the above-mentioned first shell grains onto the swing sorting body for sorting. If it is not applied, the screening performance of the sieving part of the oscillating screening body will be significantly reduced.

In addition, the concave is relatively stable in the mounted state and easy to mount and hold because the side frame and all the members forming the leaked portion form an integrated structure. A large selection net causes a lot of problems regarding strength, attachment / detachment operation during cleaning, and positioning / fastening.

Further, even if the rear wall and the concave are removed and the rear part is opened at the time of cleaning, only the straw rack of the rocking sorter can be reached, which is the most likely to cause clogging and requires cleaning in seed collection and the like. Could not clean the sorting section.

(D) Means for Solving the Problems In the present invention, a processing cylinder is provided on the side of a sorting chamber provided in the gazette of the handling chamber, with a front portion communicating with the side of the handling chamber. In a thresher provided with a processing chamber so as to face a side portion on an oscillating sorting body of the sorting chamber, the processing chamber is configured by an outer side wall and a processing drum receiving net located inside and extending from an upper portion to a lower portion. Together with the processing cylinder, the side wall of the processing chamber is attached to the machine wall such that the lower part is detachably or rotatably attached to the machine wall, and the upper part is bent upward at the upper end so that the machine frame has its outer surface. Between the machine frame and the bent portion at the upper portion of the side wall by upwardly bending the upper portion of the receiving frame of the processing cylinder receiving net by engagingly and disengageably locking it with a fastener in a posture facing It is inserted and is releasably locked to the stopper, and the upper part of the side wall and the upper part of the net frame are tightened together on the machine frame with the tightening device. By contacting, the above-mentioned problems were solved.

(E) Action Shell grains and small straw debris in the grain that have been threshed in the handling chamber after threshing the culms fall from the net onto the rocking sorter and are wind-selected and sieve-sorted. The first shell grains are collected outside the machine, the second one is reduced second, and the dust is discharged outside the machine.

Then, the long straws and panicles that have moved to the rear part of the handling room move to the processing room from the side of the handling room and are processed by the processing cylinder, and the single grained shell grains and small straws in the processed material are processed. The wastes are sorted by swinging from the handling chamber processing net extending from the upper part to the lower part onto the swing sorting body by merging. During the above-mentioned procedure, both the side wall and the upper part of the receiving frame of the processing drum receiving net are bent, so even if a large pressure is applied during processing, they will not be deformed and the spacing between the processing drum and the receiving net is appropriate. It is possible to carry out an appropriate processing while maintaining a proper state.

Then, when the processing chamber and the rocking sorting body are cleaned, when the fastening tool is released, the fastening of the side wall and the upper part of the processing drum receiving net is released at the same time. By pulling it upward while holding the bent portion on the upper part of the frame, it is possible to easily clean the processing drum support net and also to easily clean the main part of the swing selection body.

After the cleaning is finished, if the processing cylinder support net is inserted from above and locked to the fastener, the upward rising portion of the above-mentioned receiver net is overlapped with the outer surface of the machine frame for accurate positioning and support. This can be done, and then the side wall is closed and the upper part thereof is locked to the fastener, and the upwardly bent portion is overlapped with the rising portion of the net frame. When the fastener is operated in this state, the receiving frame and the bent portion of the upper portion of the side wall can be fastened simultaneously and with one touch.
