Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain feeding and sorting device for a rice huller.

Problems to be Solved by the Invention A sorting device in the form of a sorting cylinder that removes supplied paddy with a shedding device, mixes the washed brown rice and paddy, receives the washed rice, and sorts it while rotating. In this case, the supplied grains form a grain layer in the sorting cylinder, and the grains are sorted while being transported.

This increase or decrease in the supply amount causes fluctuations in the grain layer within the sorting cylinder, which tends to affect sorting performance.

Means for Solving the Problem This invention has a recess (1) on the inner circumferential surface into which grains can fit.
't- Sorting tube (2) that forms and separates grains by rotation.
A sensor (3) is installed inside the sorting tube (2) that rotates up and down depending on the layer thickness of grains supplied at the starting end of the sorting tube (2). device (
A control valve (5) for adjusting the amount of paddy to be supplied to 4) is configured to be linked in the closing direction and in the opening direction when decreasing, and
A plurality of guide plates (6) are installed coaxially with the sensor (3) to guide the grains deposited with the lower edge close to the lower inner peripheral surface of the sorting tube (2) toward the terminal end of the sorting tube (2). The grain supply sorting device of the huller is configured to rotate in the same direction as the sensor (3) above.

Functions and Effects of the Invention In order to sort the grains by rotating the sorting tube (2), the layered rice is removed by the shedding device (4).

The supplied grains are fed into the starting end of the sorting tube (2), and the supplied grains form an appropriate grain accumulation layer required for sorting on the inner circumferential surface of the sorting tube (2), and are dented on the upward rotation side. C1) performs the sorting action of the ascending sorting process where it is scooped up and the descending process where it falls, and the grains that fall and the grains that accumulate at the starting end of the sorting tube (2) are sorted by the guide plate (6). Sorting tube (
2) Sorting is performed repeatedly while being guided and transferred to the terminal side, but for example, if the rotation speed of the sorting tube (2) changes during the operation, or due to fluctuations in the shedding rate, etc., the sorting tube (2) )
When there is a change in the amount of grains fed into the starting end, the sensor (3) rotates up and down depending on the grain layer thickness at the starting end.
As the supply rate increases and the grain layer becomes thicker, the sensor (3
) is moved up to adjust the opening degree of a control valve (5) that adjusts the amount of paddy to be supplied to the removal device 21 (4) in the closing direction.

Conversely, if the supply decreases and the grain layer thickness becomes thinner,
The senner (3) moves downward to adjust the opening degree of the control valve (5) to supply to the shedding device (4) in the opening direction, thereby stabilizing the layer thickness of the grain sediment layer. At the same time, the information board (
6) rotates up and down following the movement of the sensor (3),
Even if the number of grains to be supplied increases, the grains can be dammed up by the guide plate (6) to reduce local retention, and the grains can be guided and transferred to the terminal end of the sorting tube (2) for leveling. While forming a grain accumulation layer according to the amount of grains supplied, the sensor (3
) can be quickly returned to a deposited layer suitable for sorting.
