Description

Description: TECHNICAL FIELD The present invention relates to a rotation speed control device for a rotary sorting device in a hull sorting device.

[Prior art]

A hulling device consisting of hulling rolls and a sorting cylinder that has many jar holes on the inner peripheral surface and rotates around the horizontal axis. Rotary sorting device for sorting 12
There is a huller made up of.

[Problems to be solved by the invention]

In the case of conventional hulling machines, a sorting cylinder with a large number of jar holes on the inner peripheral surface is rotated around the horizontal axis, and grain is selected when sorting out the unpolished rice in the hulling device into hull and brown rice. Regardless of the moisture value of the rice or the mixing ratio of immature rice in the grain to be hulled, the sorting cylinder rotates at a constant number of rotations for sorting,
There was a problem that paddy was mixed with brown rice and the sorting accuracy was not improved.

Therefore, the present invention seeks to eliminate such drawbacks.

[Means for solving problems]

This invention relates to the immature rice mixing rate of the immature rice detecting means for detecting the immature rice mixing rate of the hulling grain, and the detected water value of the water detecting means for detecting the water value of the hulled grain, High water content detection of the water content detection means, and in connection with the large amount of immature rice detection of the immature rice detection means, the rotation speed of the selection cylinder of the rotation selection device 12 is adjusted to the decrease side, or the water content detection means In connection with the detection of low water content and the detection of a small amount of unripe rice, the rotation speed of the selection cylinder of the rotation selection device 12 is adjusted to the increasing side to solve the drawbacks of the conventional device.

[Operation and effect of the invention]

The unpolished rice that has been hulled by the hulling rolls 1 and 1 is, after being wind-selected, supplied to a sorting cylinder of the rotary sorting device 12 and separated and sorted into hull and brown rice. In such a hulling selection process, the moisture value of the hulled grain is detected by the moisture detecting means, and the unripe rice mixing ratio of the hulled grain is detected by the unripe rice detecting means.

Then, when the water content detection means detects high water content, and the immature rice detection means detects a large amount of immature rice, a command signal for adjusting the rotation speed of the rotation selection device 12 to the decreasing side is related thereto. It is output, the rotation speed is adjusted to the decrease side, and
When the water content detection means detects low water content, and the immature rice detection means detects a small amount of immature rice, a rotation speed command signal for adjusting the rotation speed of the rotation selection device 12 to the increase side is associated with this. It is output and the sorting cylinder is adjusted to the decreasing side.

In this way, the number of rotations of the selection cylinder of the rotation selection device 12 is adjusted in relation to the moisture value of the grain and the unripe rice mixing rate, so that it is possible to reduce the paddy mixing into the brown rice and improve the selection accuracy. it can.
