Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oscillating grain sorting device, particularly to an improvement in a feed trough for supplying grain to a sorting machine.

A conventional oscillating grain sorting device has a configuration as shown in FIG. That is, 1 is a sorting board with a rough surface and stacked in multiple stages, which is tilted at an angle of inclination α by support legs 2 and 3. It is swung at an inclination angle β. 5 is a supply gutter that swings together with the sorting board 1 installed above the sorting board 1;
1 is placed on the sorting board 1 on the bottom 6 side and sorted! 81 reaches above the high part 7 and connects a plurality of distribution gutter 8 for supplying grain to each sorting plate 1. 10 is a mixed rice collection section installed in the middle lower part of the sorting board 1; 11 is the paddy rice collecting part installed in the sorting board 1;
This is the brown rice collection section located at the bottom of high section 7. 12 is located below the unhulled rice collection section 9.
Row 1''-le, 14 is rice husk wind sorting part, 15 is waste I! l therefore, 1
6 is a screw conveyor, 17 is a grain lifting machine, 18 is a tank, 19 is a brown rice 1] l outlet, and 20 is a gutter-C.

When the grains to be sorted, which are a mixture of unhulled rice and brown rice, flow down from the tank 18 to the supply gutter 5, the feed gutter 5 and the sorting board 1 are oscillating together, so the grains to be sorted are transferred to the irregularities of the supply gutter 5. The liquid gradually advances on the surface, reaches above the high part 7 of the sorting board 1, passes through a plurality of dispersion gutter 8, and flows down onto the plurality of sorting boards 1. Sorting board 1
oscillates in the direction of the width angle β from the angle α, so that among the grains to be sorted, unhulled rice is gradually sorted into the lower part 6 and brown rice is sorted into the higher part 7, and the unhulled rice is sent to the unhulled rice collecting section 9, and the unhulled rice is sent to the unhulled rice collection section 9. Brown rice flows down to section 11, and mixed grains from both parties flow down to mixed rice collection section 10. The unhulled rice flowing down to the unhulled rice convergence unit 0 is passed from the unhulled rice supply unit 12 between the two preaching rolls 133 to the unhulled rice 1.
i! The rice husks are sent to the rice husk selection section 14, where they are separated by wind separation, and then conveyed to the screw conveyor 16. The grains are carried upward by the grain lifting machine 17 and then put into the tank 18 again. The brown rice that has entered the brown rice collection section 11 is transported to the appropriate location through the brown rice 411 outlet 19.

Further, the mixed grains pass through the grain lifting machine 17 and are similarly thrown into the tank 18 again.

Although this type of oscillating grain sorting device has a greater sorting capacity than the man-goku type used in the past, it has the drawbacks of high cost and high energy consumption due to the weight of the vibrating section.

An object of the present invention is to provide an oscillating grain sorting machine that reduces product yield without reducing sorting efficiency and consumes less operating energy.

Hereinafter, the present invention will be described in detail based on the drawings.

FIG. 2 shows an embodiment of the present invention, and FIGS. 3 and 4 show an embodiment of the present invention.
It is an enlarged view of the main part.

In the embodiment of the present invention, there is a structure C' similar to that of FIG. 1 except for the supply trough.

The supply gutter 21 consists of a concavo-convex transfer surface 22 and a sieve 23 provided at a distance slightly above it. The size of the mesh of this sieve 23 is such that brown rice (escaped grains) can fall and unhulled rice cannot fall. A separating plate 24 is installed for guiding (), and a temporary 25 is installed above.
will be established. At the end of the uneven transfer surface 22, there is a ti [
Connect and cover 126. .

The grains to be sorted that have flowed down from the tank 18 to the supply l1ffI21 are oscillated together with the sorting plate 1, so that most of the brown rice smaller than 1323 is transferred to the uneven transfer surface 2.
2, is transferred to the end of the uneven transfer surface 22, flows down into the brown rice discharge gutter 26, and is carried to an appropriate location. Sieve 23
The mixed grains that did not fall further down flow down into the plurality of dispersions 1a8 in appropriate amounts by the leveling plate 25 and the separating plate 24, and are shaken and sorted on the sorting board 1 in the same way as the one in Fig. 1. .

In order to solve this problem, the present invention provides a sieve through which the escaped grains fall in the feed gutter that swings between the sorting board and the bar, so that most of the escaped grains are not distributed to the sorter, and the swinging of the sorting board Since the removal is performed using motion, the load on the sorting board is reduced, the number of sorting boards can be reduced, and the amount of energy consumed is also low, making it economical.
