Description

[Detailed description of the invention] This invention relates to a grain sorting device, and in particular, the sorting material is made to flow down onto a grain grain board with holes through which a sorting air can pass, and the sorting air is blown from below the grain board. In this method, the flow grain board is divided into left and right parts in the width direction, and the material to be sorted passes through the grain board twice on the left and right sides, increasing the sorting time without increasing the length of the flow grain board, thereby achieving high sorting performance. It was made so that it could be obtained.

Hereinafter, the present invention will be described in detail with reference to an embodiment of the present invention apparatus shown in the accompanying drawings.

1 is a machine box of a grain sorting machine that can implement the grain sorting device according to the present invention.

2 is a hopper formed on the rear upper surface of the machine box 1;
The lower part of the hopper 2 communicates with the sorting wind cylinder 3.

4 is a porous grain grain plate formed to allow sorting air to pass through, the grain grain board 4 is configured to form a relatively wide processing surface, and its upper portion faces the opening of the hopper 2; It is arranged so that it slopes downward toward the rear.

Reference numeral 5 denotes a winnowing machine disposed below the rear of the machine box 1, and the high-pressure sorting air generated by the winnowing machine 5 is passed through the wind direction plates 6, 6.
This allows the grain to be blown up from below the grain board 4. In the present invention, a grain partitioning plate 7 is used to divide the grain board 4 into left and right halves in the width direction.
are placed before and after. The grain dividing plate 7 extends from the top of the grain plate 4 into the case of a later-described grain horizontal conveyance device 8, and its left and right positions are such that the processing width on one side is wider than the processing width on the other side. Arrange it so that And the first grain board 4 on the wide side of either the left or right side (the left side in the embodiment shown in FIG. 2)
A grain transfer device 9 is provided to feed the sorted material from the lower side of the grain a to the second hopper 2b on the upper part of the second flow grain plate 4b on the other narrow side (the right side in the same).

When the flow grain plate is configured to be divided into left and right halves as in the present device, there are many foreign substances other than grains in the material to be sorted fed onto the first flow grain plate 4a, and the second flow grain plate 4b
The material to be sorted that is fed upward is subjected to the first sorting processing action by the first grain plate 4a, and foreign matter is sorted out to the second or third port, so that the first grain grain is separated from the first grain. Compared to the amount fed to the plate 4a, the second flow grain plate 4b
Even if the processing width of the second grain plate 4b is narrower than that of the first grain plate 4a, the sorting function of the second grain plate 4b does not deteriorate, and Although the entire grain plate 4 is divided into two on the left and right sides, there is no harm in doubling the overall width of the fuselage.

The above-mentioned grain transfer device 9, in the present embodiment, has a first polished grain lateral conveying device 8a below the first flow grain plate 4a and a first polished grain slurry 10 at the conveying end of the conveying device 8a. It consists of

A second horizontal grain conveying device 8b is provided below the second flow grain plate 4b, and a finished grain frying thrower 11 is attached to the conveying end of the conveying device 8b.

The conveyance directions of the first grain horizontal conveyance device 8a and the second grain polishing horizontal conveyance device 8b are configured to face opposite side walls of the machine box 1.

Further forward of both of these conveyance devices 8a and 8b, a second article horizontal conveyance device 12 is provided.

Items that are not collected by the second horizontal transfer device 12 are discharged from the third port 13 to the front outside of the machine.

In the apparatus of the embodiment, numeral 14 is a tensioning hopper, and 15 is a tensioning grain lifting machine for hoisting the grain to the hopper 2a on the side of the first grain plate 4a.

Therefore, as in the present invention, the grain flow board 4 is replaced by the grain flow partition plate 7.
The grains are divided into left and right halves by the grain board 4a, and the grains that have been sorted once on the side of the first grain board 4a are transferred to the second hopper 2b by the grain transfer device 9, and then sorted again on the side of the second grain board 4b. Therefore, a high sorting function can be obtained by increasing the sorting time without increasing the length of the grain flow board 4.
