Description

[Detailed explanation of the idea] The present invention relates to a grain sorting device.

In other words, for example, in a sorting device used when sorting a fixed amount of mixed grains of unmixed brown rice and paddy in a hulling plant, etc., a fixed amount is fed into a sorting tube and rotated in the normal direction to ensure good sorting. In addition, by reversing the rotation, the grains remaining inside can be effectively discharged, and when rotating in the forward direction, the grains remaining inside can be maintained well so that they are not discharged, and the sorting performance can be improved, making it easy to use. The present invention is provided in such a way that it can be suitably implemented with a simple structure.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a cross-sectional view of the entire sorting device, where A is a cylindrical sorting tube with a large number of sorting holes 1 on its circumferential surface, and one end of the sorting tube A is integrated with an open truncated conical part a. A disc-shaped face plate 3 having a slightly larger diameter than the sorting cylinder A is fixedly fixed on the other end side so as to close it, and the face plate 3 is adjacent to the inner peripheral side of the sorting cylinder A and has a diameter of 180 mm. Openings 4°4 are provided at two locations with a degree phase difference, and one side of the openings 4, 4 is in contact with the inner peripheral surface of the sorting tube A, and the sorting tube A faces the openings 4, 4. Guide pieces 5.5 which are inclined with respect to the rotational direction of the face plate 3 are provided oppositely, and discharge gutters 6, 6 are connected to the outside of the face plate 3 and communicate with the openings 4, 4, respectively. Face plate 3
The lower openings 7 on the other end side are formed so as to open outward at a position near the opening 4 on the other side.

A boss 9 supported by an arm 8 is installed at the inner center of one end of the sorting cylinder A to be loaded into the inside of the body B.
A shaft 10 of a forward/reverse motor M installed in
The supply gutter 14 at the bottom of the hopper 13 is visible inside the truncated conical part a of the sorting tube A, which is connected concentrically and horizontally suspended with its axial direction horizontal. There is a receiving gutter 1
5, and a receiving gutter 16 is installed on the lower side of the discharge gutter 6, 6, respectively, and a souffle bar 17 is installed above the sorting tube A in contact with the outer peripheral surface of the sorting tube A. .

Then, a certain amount of mixed grains of brown rice and paddy, which are demixed rice, are supplied from the supply gutter 14 into the sorting tube A as shown by arrow A in FIG. 1, and the sorting tube A is moved by motor M as shown in FIG. When the rice is rotated in the normal direction as shown by the arrow in FIG.
The guide pieces 5, 5 installed opposite to the frontage 4, 4 are pushed back to one end side.
The brown rice flows through the sorting tube A without flowing into the sorting tube A, and the brown rice leaks from the sorting hole 1 and falls into the receiving gutter 15, and the rice that does not leak through the sorting hole 1 remains in the sorting tube A.

When discharging the paddy remaining in this sorting tube A, when the sorting tube A is reversed as shown by the arrow in FIGS. is guided into the openings 4, 4 in a scraping manner, and the opening 4
, 4, the paddy flows into the discharge gutter 6 which rotates in reverse along with the sorting tube A.
, 6 flows down into the open lower, flows downward from 7, and flows into the receiving gutter 1.
It will be received on the 6th.

In this way, the present invention has a sorting cylinder which is horizontally mounted so as to be able to rotate forward and backward, and which is provided with a face plate that supplies grains from one end and prevents the grains from flowing out at the other end. An opening is provided in the area adjacent to the opening, and guide pieces are provided facing the inner surface of the opening and inclined with respect to the rotational direction of the sorting cylinder.This structure allows grains to be removed without rotating the sorting cylinder in the normal direction. When sorting, the face plate prevents grains from flowing out to the other end, and the guide piece pushes the grains back to one end, preventing them from flowing into the opening, allowing the sorting action to continue and improving sorting performance. When the cylinder is reversed, the guide piece scrapes up the grains remaining in the sorting cylinder and guides them to the opening and discharges them. Grain sorting can be conveniently carried out by reversing the sorting cylinder in the forward and reverse directions. , has the advantage that it can be implemented conveniently with a simple structure.
