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 potholes on its inner peripheral surface. It is something.

[Prior Art] There is a grain sorting machine that sorts a mixed rice of paddy and brown rice by rotating a rotary sorting cylinder, which has a large number of potholes on its inner peripheral surface, around a horizontal axis. Inside this rotary sorting cylinder, an intermediate return shelf is installed at the longitudinal midpoint from the supply side to the discharge side below the finishing rice gutter, and a discharge side return shelf is installed obliquely on the discharge side. The grains that have not reached the finishing rice gutter in the upper part of the grains that have been pumped up by the cylinder, that is, the grains that are mixed with a relatively large amount of brown rice, are transferred from the front side of the rotating sorting cylinder to the rear side of the rotation. The grains are guided to flow down and returned to the rear of the rotational direction of the fluidized bed of the grains to be sorted formed by the rotation of the rotary sorting tube, so that the grains are mixed with a relatively large amount of brown rice. This increases the chances of the rice entering the hole, increasing the efficiency of collecting brown rice into the finished rice gutter.

[Problem that the invention seeks to solve]

However, in this conventional device, the intermediate reduction seeds and the discharge side reduction shelf are fixedly arranged in the longitudinal direction below the finishing rice gutter. Due to the difference in varieties depending on the grain size, there was a problem that the intermediate reducing species and the discharge side reducing shelf did not effectively reduce grains containing a large amount of brown rice.

Therefore, the present invention is designed to respond to changes in the sorting state based on differences in variety due to the size of the grain or the difficulty of shedding.
The relative position between the intermediate reduction seeds and the discharge side reduction shelf can be adjusted, and in connection with this adjustment, the paddy supply control valve in the husking section or the grain supply control valve to the rotary sorting tube can also be adjusted. At the same time, the amount of grains supplied to the rotary sorting cylinder is adjusted to improve the sorting efficiency. This aims to improve the feed rate and optimize the amount of feed to the single-rotation sorting tube.

[Means to solve the problem]

The technical means of the present invention for solving such technical problems is to provide a finished rice with a finished rice regulating valve 16a inside a rotary sorting cylinder 11 which has a large number of potholes in its inner circumferential surface and rotates about a horizontal axis. The gutter 16 is hung horizontally, and an intermediate reduction species 23 is provided diagonally below the finished rice gutter 16 in the middle in the longitudinal direction from the supply side to the discharge side, and a discharge side reduction shelf 24 is provided diagonally on the discharge side. At the same time, the discharge side reduction shelf 24 is arranged lower than the intermediate reduction [23], and at least the discharge side end of the intermediate reduction species 23 is configured to be freely adjustable in the longitudinal direction above the discharge side reduction shelf 24, and the intermediate reduction Reduction seeds 23 and paddy supply control valve 28 of the husking section 1
Alternatively, the adjustment device for the grain sorting device is configured to adjust the grain supply control valve to the rotary sorting tube 11 in conjunction with the control valve.

[Function and effect of the invention]

When performing sorting work in the rotary sorting tube 11, the sorting situation in the rotary sorting tube 11 changes due to differences in varieties due to the size of the grains or the difficulty of shedding, and the sorting conditions in the rotary sorting tube 11 change. The situation in which the grains are pumped up in step 111 changes, and the intermediate reduced seeds 23 and the discharge side reduction shelf 2
4, the discharge side of the intermediate reduction seed 23 is moved to the discharge side, and the grains with a large amount of brown rice received in the intermediate reduction seed 23 are given priority and are transferred to the pot of the rotary sorting cylinder 11. It provides an opportunity for the brown rice to fit into the hole, increases the opportunity for pumping up the brown rice, and improves the sorting efficiency. When it is ready to receive, the rotary sorting cylinder 11
Since the amount of grains to be sorted in the hull is increasing, the paddy supply control valve 28 of the husking section 1 or the grain supply control valve to the rotary sorting cylinder 11 is adjusted to the decreasing side at the same time. , it is possible to optimize the amount of grains to be sorted in the rotary sorting ill and improve the sorting accuracy.
