In the prior art, for example, the structure is as disclosed in Japanese Utility Model Laid-Open No. 56-121476.

Therefore, when the end of the sorting cylinder is removed, the end of the sorting cylinder may hit the partition wall from above and the portion may be deformed or damaged.

Also, in the case where a plurality of sorting cylinders are arranged one above the other, large particles that flow out from the inner end of the upper sorting cylinder are thrown into the outer periphery of the lower sorting cylinder and then through the sorting holes. There are problems such as mixing into the leaked small particles.

(C) Problems to be solved by the invention As described above, in the conventional configuration, when the end of the sorting cylinder is removed, the end of the sorting cylinder hits the partition wall from above and this portion is Deformation or damage, or in the case of a configuration in which a plurality of sorting cylinders are arranged one above the other, large particles flowing out from the inner end of the upper sorting cylinder are The present invention has a problem such as jumping into a crocodile and being mixed into small particles that have leaked from the sorting hole. Therefore, the present invention eliminates such conventional problems and deforms the terminal end of the sorting cylinder when removing the sorting cylinder. It was devised for the purpose of eliminating damage and preventing the large particles sorted together from mixing into the small particles.

(D) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention has a grain size obtained by rotatably laterally extending a sorting cylinder having a large number of appropriate sorting holes formed on the circumferential surface. In a sorting machine in which the sorting cylinder is detachable, the end of the sorting cylinder has a relatively short-length support shaft projecting outward in the axial direction from the shaft core portion to the outside. At the tip of the support shaft, a bearing part that can be slidably fixed in the axial direction and mounted on the machine wall can be inserted and removed, and a grain jump-in prevention plate that covers the end of the sorting cylinder is provided. ,
When the bearing shaft is vertically provided between the terminal end portion and the bearing portion and the spindle is inserted into a guide hole provided in the grain jumping-in prevention plate to separate the bearing portion from the tip end of the spindle, the spindle is guided into the guide hole. It was configured to be supported by the department.

(E) Operation With this configuration, the large and small mixed particles are flowed from the starting end to the terminating end of the sorting cylinder, and the small particles in the sorting product are leak-sorted through the sorting holes. The sorted material supplied therein is biased upward by the rotation of the sorting cylinder, and is lifted up and stirred, and the small particles in the sorted material leak through the sorting holes and are sorted.

Then, during this sorting, the terminal end of the sorting cylinder is covered with the grain jumping-in prevention plate so that the large grains flowing out from the other terminal end inside the sorting cylinder do not jump in.

Also, when removing the sorting cylinder for cleaning, or when replacing the sorting cylinder with a different sorting hole, if the bearing is unfixed and slid out of the machine, it will come off from the tip of the spindle. . Then, the support shaft is once supported by the guide hole of the jump-in prevention plate so that the end of the sorting cylinder does not hit the partition wall. Then, the support shaft is pulled out from the guide hole and the sorting cylinder is removed. is there.

A plate, (12) is an extraction gutter for picking up and receiving large particles that do not leak from each sorting cylinder (1) ... and the end of which flows out of the sorting cylinder, and (13) ... is the starting end of each sorting cylinder (1). Supply gutters (14) for supplying the sorted matter to the gutters (14) ... Are discharge pipes for taking out relatively large, medium and small small particles from the small grit provided at the bottom of the receiving gutter (9).

Therefore, when each part is rotated by the motor (M) in the direction of the arrow, the sorted products supplied from the respective supply gutters (13) ... into the sorting cylinder (1). While small particles are leaking through the sorting hole (2) and sorted, the small particles that leak from the upper sorting cylinder (1) (1) are guided by the chevron (11) to the trough (9). Anything that falls and leaks from the lower sorting cylinders (1) (1) directly drops to the gutter (9), is conveyed by the screw conveyor (8), and is taken out from each discharge cylinder (14). Large particles that do not leak from the sorting cylinders (1) ... flow out from the end and fall into the extraction trough (12) to be taken out.

And, the clogging remover (7) (7) and the sorting cylinder (1) (1)
(1) The clogging is removed by striking the outer peripheral surface at the same time straddling (1).

Next, a device for removing the sorting cylinder, which is an essential part of the present invention, will be described.

By the way, since the same removing device is applied to each of the sorting cylinders (1) arranged in parallel in the upper and lower two stages, one of the sorting cylinders arranged in the lower stage will be described, and the other three sorting cylinders (1) will be described. The same reference numerals are given to those and description thereof will be omitted.

The end of the sorting cylinder (1) has a shaft (3), which is relatively short in the axial direction, supported by a supporting rod (15) from the shaft center portion thereof, and is protruded outward. A bearing portion (5) having a ball bearing is fitted into the machine wall (4) and slidable in the axial direction,
Further, it is fixedly attached by a set bolt (16), and the tip end (3a) of the support shaft (3) can be inserted into and removed from the ball bearing.

(6) is a grain jump-in prevention plate that covers the end of the sorting cylinder (1),
The upper end is joined to the partition wall (17) which stands around the lower part of the upper sorting cylinder (1), and is hung vertically between the end part and the bearing part (5), and the supporting shaft (3 ) Is provided with a guide hole (6a) through which the support shaft (3) can be inserted, at a portion corresponding to the tip (3a) of
The tip (3a) of the support shaft (3) is fitted into the ball bearing through the guide hole (6a).

(18) is a cover provided between the grain jump prevention plate (6) and the machine wall (4), and the upper part has a chevron shape and the grain jump prevention plate (6) and the machine wall (4) ) Is connected to cover the inside of the body of the bearing portion (5).

In addition, the starting end of the sorting cylinder (1) has a bearing that can be attached to the machine body.
