Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing sorting device in a hull sorting machine.

[0002]

2. Description of the Related Art Conventionally, the upper space portion on the lower tilted side of a swing selection plate is a non-utilization space.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a drive device for controlling the movement of a paddy rice discrimination sensor is provided in such a non-utilized space, so that the space is effectively used and a device for automating a sorting partition plate is provided. It is to prevent the increase in size. In order to achieve this object, the present invention has taken the following technical measures.

[0004]

That is, the technical means according to the present invention is inclined in the front-rear direction such that the supply side is at a high position and the discharge side is at a low position, and the one side of the left and right lateral directions is high and the other side is high. In the swing sorting device, the swing sorting plate 17 is constructed so that the swing sorting plates 17, 17 ...
A paddy rice discrimination sensor 40 for detecting a sorting state on the swing sorting plate 17 is provided above the discharge side of 7 so as to be laterally controllable by a driving device 41, and a drive for controlling the movement of the paddy rice discrimination sensor 40. The device 41 is a swing sorting device of a hull sorting machine, which is arranged on the discharge side of the swing sorting plates 17, 17, ... Above the lower swing side of the swing side.

[0005]

The mixed rice fed to the rocking sorting plates 17, 17, ... Is sorted by the reciprocating swinging of the sorting plates in the diagonally upward and downward directions in the horizontal direction. It is separated by a partition plate 20 and taken out, passed through a brown rice sink plate 22 and a brown rice gutter 23, and then fried by a brown rice fried machine E and taken out of the machine.

A hulled rice discriminating sensor 40 for detecting the sorting state on the swing sorting plate is laterally and laterally controlled by a driving motor M2 of a driving device 41. When the unhulled rice discrimination sensor 40 detects a certain amount of unhulled rice, it determines the proper position of the unpolished rice partition plate 20 based on the detection result, and commands the control motor M1 to drive through the control means to unpolished rice. (Finished rice)
The partition plate is moved and controlled to a position where the paddy does not mix inside.

When the drive device 41 of the paddy rice discrimination sensor 40 is arranged in the upper space on the lower slope side of the rocking sorting plates 17, 17, ..., This upper space is effectively utilized.

[0008]

Therefore, according to the present invention, since the drive unit of the paddy rice discrimination sensor is provided in the space above the grain discharge side of the rocking sorting plate and in the upper side of the lower tilting side of the rocking sorting plate, such space is provided. Can be effectively utilized, and it is possible to prevent the device from becoming large due to the automation of the movement control of the partition plate.
