2. Description of the Related Art Conventionally, in a case where sorting is performed by dropping unhandled materials from a handling chamber and those processed in the processing chamber into a swinging sorting body for sorting, a discharge opening at the end of the processing chamber is performed. The dust discharged from the dust outlet is vigorously ejected by the rotation of the processing cylinder, and the end of the swinging sorter is discharged to the upper part of the wobbling, so that the swinging sorter swings the sorting action. Some of them are discharged directly to the outside of the machine, some of them collide against the walls of the dust chamber and are stagnant and aggregate, and they are discharged without being sorted, resulting in dust from the dust outlet. The grains contained inside are not collected and are discharged to the outside of the machine, resulting in No. 3 loss. Also, since the dust is vigorously discharged onto the rocking sorting body, the culling etc. will cause the rocking sorting body to go out. There is also a drawback that it passes through and falls to the second lower gutter and circulates inside the machine, which adversely affects the sorting performance. To have.

[0003]

Therefore, in order to solve the drawbacks described in the preceding paragraph, the present invention provides a sorting action by swinging and dust selection of the dust discharged from the dust outlet at the end of the processing chamber. It is effective, and the grain contained in this dust is recovered to eliminate the loss of No. 3, and the drop of what should be discharged out of the machine into the No. 2 trough is stabilized and the sorting performance is stable. The purpose is to let you.

[0004]

In order to achieve the above-mentioned object, the present invention provides that the unprocessed material from the handling room and the unprocessed material from the dust inlet of the handling room are processed in the processing chamber. The following means have been taken in the case where the above-mentioned is dropped and sorted on the rocking sorting body mounted from the lower side of the handling chamber to the dust-exhausting chamber. That is, there is provided a cover cover for forming a dust discharge path toward the suction suction dust collecting fan facing the upper side of the swing sorting body from the dust outlet opening at the end of the processing chamber. ,
It was constructed by vertically arranging wall plates at appropriate places on the cover.

[0005]

With this configuration, the unloaded material from the handling chamber and the processed material falling from the processing chamber are supplied onto the rocking sorting body, and the rocking action of the rocking sorting body and the sorting wind blown from below. In that case, the dust discharged from the dust outlet opening at the end of the processing cylinder chamber is ejected vigorously by the rotation of the processing cylinder, and the dust discharge path is sucked in. The fan flies towards you. Further, since the dust particles flying in the dust discharge passage fly in the dust discharge passage formed by the cover, they fly in a collective state.
Moreover, it is not affected by the sorting wind that blows backward on the rocking sorting body or the sorting wind that is sucked by the suction / dust fan.

[0006] Then, the dust discharged in the dust discharge passage impacts a wall plate vertically installed in a proper position, stalls, disperses and falls, and a sorting wind blows backward toward the falling wind. After being wind-selected by the method, the particles are subjected to the rocking action of the rocking sorting body, and all the grains contained in the dust are collected.
