Description

[Detailed explanation of the invention] In this invention, a grain sorting plate 2 is mounted on the machine frame 1 at an angle, and a supply port 3 is mounted on the upper part.
, an oscillating grain sorting machine having a structure with a discharge port 4 at the lower part and giving circular motion and vertical motion to grains, in which an arc-shaped baffle plate 5 curved toward the lower part is supported on the upper surface of the grain sorting plate 2. The present invention relates to a grain sorting device.

The grain selection board 2 is a wire mesh sieve or a sieve made of perforated plates, and is supported in one or more stages (a three-stage version is shown in FIGS. 1 and 2), and each grain selection board 2 has plates 6 on both sides. .6 and a discharge port guide plate 7 are provided.

Vibration generating frames 8 are brought into contact with the lower surface of this grain sorting board 2, and vibration generating soil 9 is enclosed in each frame 8.

The upper end of the arc-shaped baffle plate 5 includes the side plates 6, 6 and the solid bearing plate 1.
The arc-shaped baffle plate 5 is moved from the grain selection plate 2 by pulling the upper end of an upward arm 12 provided on the pin 11 with a spring 13. Press it against the top surface.

The grain sorting plate 2 thus constructed is mounted on the machine frame 1 by means of a hanging edge 14, etc., and a horizontal eccentric rotation pin 15 is connected to the lower surface.
The eccentric rotating pin 15 is moved circularly in the horizontal direction by the upright rotating shaft 16, and the grain selection plate 2 is moved in a circular manner in the horizontal direction. The grains on the grain plate 2 are given circular motion and vertical motion at the same time.

In the figure, 17 indicates the prime mover, and 18 indicates the vertical rotation shaft 16.
21 is a connecting fitting between the eccentric rotation pin 15 and the vibration generating frame 8, 22 is a support net for the vibration generating soil 9, and 23 is a string connecting the pulley 19 provided in 3rd stage under-sieve guide plate, 34 is a dust discharge blower, 135 is a raw material grain supply hopper, 36 is a raw material grain dividing plate, 37 is a pin 11
38 is a leaf spring that presses against the side arm 37;
' is an arc-shaped baffle plate that connects the arc-shaped baffle plates 5.5.

Therefore, when the prime mover 17 is started and the inclined grain selection plate 2 is moved circularly in the horizontal direction to supply raw grains to the supply port 3, the grains are distributed along the inner periphery of each arc-shaped baffle plate 5 on the grain selection plate 2. At the same time, the grains move in a circular motion along the inclination, and the grains are almost evenly spread inside each arc-shaped baffle plate 5, and each grain is sieved vertically by the sieving holes of the grain sorting board 2, and is also tilted. The grains descending along the grain sorting plate 2 abut against the arc-shaped baffle plate 5, and when they get over this, they turn around and enter the next baffle plate 5, and the same operation as described above is repeated.

At the end of the working day, the grains stopped by the baffle plate 5 are removed by tilting the upward arm 12 from the solid line position in FIG. The lower part of the plate 5 can be caused to flow downward.

The grains may be paddy, brown rice, white rice, or other cereals.

The two most popular conventional sorting machines are the oscillating reciprocating motion type and the circular motion type, but in both of them, the sorting mesh surface is a horizontal plane regardless of the diameter of the circular motion of the drive device or the pitch of the reciprocating motion. A sorting net is attached, and its drive, sorting action, and movement conditions for the grains to be sorted lack rationality in terms of selection, and the sorting effect is extremely low.

That is, when grains are fed to the sorting surface and given a circular motion, the grains accumulate in the center of the circular motion, and the grains cannot be distributed in the periphery, so the efficiency per area becomes less than ÷.

Therefore, although a device for sorting using a circular frame has been devised, a device for mass processing has not yet been developed.

This is thought to be due to the difficulty in discharging the grains after sorting.

Since this project is configured as described above, the grain selection board 2 is large (10
00mm x 3600mm), and because of the circular and vertical movement of the grains, the grains are less likely to be deposited in the center of the circular motion, and the grains can be applied to the sieve in a single layer. Not only that, when each grain crosses the arc-shaped baffle plate 5, it turns and tilts, and the synergistic effect of the turning action and the circular motion allows for highly efficient sorting of grain shapes, improving sorting efficiency and reducing the sorting area. This has the practical benefit of reducing equipment area and equipment costs.
