Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary sorting device for sorting grains that have undergone a de4 action.

The rotary sorting device is a device that sorts the grains picked from the huller into paddy and brown rice by rotating a sorting tube.

As is well known, since the rotary sorting device is used to sort grains into grains, a number of recesses of a predetermined shape and a predetermined diameter are formed inside a rotatably formed sorting cylinder. This recess is provided to insert the dehulled grains and feed them into the finished rice helix, so if foreign matter such as bran or dust accumulates inside the recess, the four parts become gradually shallower. When the heap reaches a certain value or higher, it becomes difficult to insert brown rice and send it to the finishing rice bowl. Therefore, in order to prevent the sorting performance of the rotary sorting device from deteriorating, the operator must periodically remove the sorting tube and remove foreign matter stuck in the recesses. However, in order to perform such cleaning work, it is necessary to loosen the knob bolt that fixes the rotary sorting device to the selection section and then pull out the handle, which is a very time-consuming task. I can't stand it. Furthermore, since it is not possible to check the degree of clogging of the recess from the outside, it is often necessary to take out the six sorting tubes when cleaning is not necessary.

SUMMARY OF THE INVENTION Accordingly, the present invention aims to improve the above-mentioned drawbacks of the prior art, and its object is to provide a rotary sorting device which issues a warning to the operator when it detects that 1 tI of foreign matter has accumulated in the recess.

A feature of the present invention that achieves the above object is that the inner circumferential surface has a plurality of recesses, and the grains are inserted into the recesses and transferred in the y-direction of rotation for sorting. In a rotary sorting device equipped with a sorting tube, a detection means 70 for detecting foreign matter clogging in the recess is provided, and a means 80 for issuing a warning or stopping the rotary sorting tube based on this detection is installed in the rotary sorting device. be. A detailed explanation of the present invention is given below with reference to the drawings.
