Abstract

PURPOSE:To facilitate the attachment and detachment of the rotary classification cylinder by providing a detachable opening in one side wall of the cylinder in its axial direction and enabling the end of a reduction shelf to retreat into the inner peripheral side of the cylinder. CONSTITUTION:When the rotary classification cylinder 11 is detached, an outer supporting plate part 10e is detached from the inner supporting plate part 10d of the rear side plate 10c, and then the outer supporting plate part 10e of the rear side plate 10c is detached from a classification case 10. A detaining cylinder 34 is then moved to the left against a spring 37 and disengaged from a detaining round hole 32, an adjusting arm 30 is turned to engage the detaining recess 36 of the detaining cylinder 34 with the detaining round hole 32, and a layer thickness detector 26 is retreated into the inner peripheral side. A handle 49 is then operated to turn a lever 48 upward and to raise the rear part of the cylinder 11, and the cylinder 11 is moved backward in its axial direction. The detaching work is facilitated in this way.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a huller sorting machine that sorts a mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of potholes on its inner circumferential surface. can be used.

[Prior art and problems to be solved by the invention] Rotary sorting that sorts mixed rice of paddy and brown rice using a rotary sorting tube that has a removal part that removes the hulls and a number of potholes on the inner circumferential surface. There is a rice hulling sorting machine that is equipped with a section.

In this type of rice hulling sorting machine, it is necessary to remove the rotary sorting tube from the machine body for inspection, maintenance, and cleaning of the rotating sorting tube.

A conventional device for removing this rotary sorting cylinder from the machine body is disclosed in Japanese Utility Model Application No. 61-171578. This conventional device includes a layer thickness detector that can detect the amount of grains to be sorted in the rotary sorting cylinder, and a finishing rice trough that receives the brown rice scraped up by the single-rotation sorting cylinder.

Alternatively, a return shelf is arranged below the finishing rice trough, and the lower outer circumference of the rotary sorting cylinder is supported by a drive roller and rotated.

For this reason, when the rotary sorting tube is pulled out from the machine body in the longitudinal direction, it collides with the finishing gutter or layer thickness detector on the inner peripheral side, making it difficult to remove.

The contact support part between the rotary sorting tube and the drive roller is provided to prevent the rotary sorting tube from shifting in the longitudinal direction.

A driving cylinder 15 with a flange that protrudes in the outer circumferential direction is provided, and when removing the rotary sorting tube, there is a problem in that the rotary sorting tube must be lifted by the height of the flange and then pulled out.

Therefore, the present invention aims to solve these problems.
