Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain sorting device for sorting mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of pot holes on its inner circumferential surface. More specifically, the present invention relates to a cleaning device for the pot hole of this rotary sorting cylinder.

[Prior art and problems to be solved by the invention] Grain sorting in which mixed rice of paddy and brown rice is sorted by rotating a rotary sorting cylinder, which has a large number of pot holes on its inner circumferential surface, around a horizontal axis. There is a device.

This type of grain sorting device has the disadvantage that dust such as grain powder accumulates in the pot hole of the rotating sorting tube, reducing sorting efficiency. Therefore, it is known to use a brush roll to clean the pot hole of the rotary sorting tube, but since the brush linear bodies that constitute this known brush roll protrude in a radial direction with respect to the rotation axis, As shown by the imaginary line in FIG. 1, it bends before entering the pot hole, causing the tip to come into contact with the inner circumferential surface of the pot hole, making it impossible to clean it thoroughly.

Therefore, this invention attempts to improve the contact condition of the tip of the brush linear body by specially devising the brush linear body that constitutes the brush roll, thereby improving the cleaning of the pot hole. .

[Means to solve the problem]

The technical means of the present invention for solving such technical problems is that a rotary sorting tube 11, which has a large number of pot holes formed on its inner peripheral surface and rotates about a horizontal axis, is provided with a container for cleaning the pot holes 1a. The brush roll 25 is rotatably supported, and the brush roll 25 is
The brush linear body 25b constituting the brush linear body 25b is characterized in that the proximal end portion is aligned substantially in the radial direction, and the distal end portion is inclined with respect to the proximal end portion so that the distal end side is located on the upper side of rotation. The cleaning device for the rotating sorting tube has the following structure.

[Function and effect of the invention]

Cleaning work is carried out by rotating the brush roll 25 while bringing it into contact with the pot hole 1a of the rotating sorting Wll. The brush linear body 25b is bent before entering the pot hole 1a, but the tip of the brush linear body 25b is bent so that it is located on the upper side of the pot hole. When entering the upper inner peripheral surface of 1a,
The bent brush linear body 25b rapidly extends and reaches the lower end of the pot hole 1a without scraping the dust on the inner peripheral surface of the pot hole 1a with its tip, so that its cleaning action is good. In addition, since the tip of the brush linear body 25b is bent so that the tip side is located on the upper side of the rotation, the brush linear body 25b is bent before entering the pot hole 1a.
When it enters the upper end of the pot hole 1a, it expands rapidly, so compared to the conventional device where the bent brush linear body gradually expands, the time it is bent is shortened.
Accordingly, the brush linear body 25b is less prone to bending and its durability can be improved.
