Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust removal device for sorted grain in a grain sorter.

In other words, in a grain sorting machine that has a spiral conveyor mounted inside a gutter installed inside a pot-hole type rotary sorting drum, grains sorted by the pot-hole type rotary sorting drum and carried out are To provide a device that can reliably and efficiently remove dust, has a simple structure, and can be suitably implemented.

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

Figure 1 shows a partially cutaway side view of the paddy sorting machine.
Inside the long wind sorting box (c) at the bottom is equipped with a suction dust remover αX, a mixed rice conveyor (8), a finishing rice conveyor (9), etc., and on the side there is a mixed rice thrower αO) and a finishing machine. A rice thrower (C11) is equipped with a hopper (2) and a hopper (2) and both deweighing rolls are installed above one end of the wind sorting box◇.
C) is installed and constructed in the same manner as the conventional structure.

In addition, a grain sorter (8) is installed above the other end of the wind sorting box 0, and this sorter (6) has a large number of pot holes on the outer peripheral surface at the top and bottom of the case (a). A double rotary sorting cylinder (1) (la) with openings at both ends is installed so as to be rotationally driven by drive wheels (b) on both sides of the lower part, and inside the upper rotary sorting cylinder (1). Each has a spiral conveyor (3) α6)
A receiving gutter (2) and a conveying gutter αη are installed, and the conveying gutter (Lrf) is installed so that it communicates with the upper tank (G) that communicates with the mixed rice thrower αQ. Torso (
A receiving gutter (2B, ), and one end side of the rotary sorting cylinder (1a) is still connected to the receiving gutter (2a) so that it communicates with the mixed rice conveyor (8) side.
The other end is connected to the finished rice conveyor (9) via a gutter (goods).
It is installed in such a way that it communicates with the sides, and has the same structure as the conventional structure.

The lower end of the carry-out gutter (4) communicating with the terminal end of the receiving gutter (2) and extending downward in the vertical direction is connected to the rotary sorting cylinder (1a).
It is installed so as to look inward on one end side, but a lower part is installed at the part that becomes the terminal end of the spiral conveyor (3) and communicates with the end of the receiving gutter (2), and the upper end of the carrying out gutter (4). A somewhat wide communication chamber (5) with stepped surfaces is formed at the side, and a dust suction machine (6) having blades coaxial with the spiral conveyor (8) is connected to the outside of the communication chamber (6). Then, the dust extractor (
Between the suction side of 6) and the outside surface of the communication chamber (5), a net (goods) that does not allow grains to pass through is installed, and a dust exhaust pipe (goods) is extended from the dust suction device (6). Set and configure.

Therefore, the mixed rice that is unweighed by the huller (C), winnowed in the winnowing box 0, and fed to the rotating sorting barrel (1) above rotates as shown by the arrow (A). The mixed rice with a small amount of paddy is subjected to primary sorting by the rotating sorting cylinder (1) in the same way as in the conventional type, and is received in the receiving trough (2).The mixed rice is transferred to the spiral conveyor (3).
It is conveyed as shown by the arrow (b) and passes through the conveying gutter (
4), the paddy that remains in the rotary sorting cylinder (1) is sent out again to the hulling machine (C), and is sent through the carry-out gutter (4) and into the rotary sorting cylinder (a) below. The mixed rice is sorted as it is, and the brown rice sent through the receiving gutter (2a) is passed through the brown rice thrower -αη.
The mixed rice taken out by the rotary sorting cylinder (1a) is thrown up again by the mixed rice thrower α and is re-sorted.

In that case, from the end of the receiving gutter (2) to the spiral conveyor (3)
The mixed rice sent out by the step surface (z
The dust flows and spreads as shown by the arrow (C) on the top of the screen (C), and the abrasive particles pass through the screen (C) and pass through the dust suction machine (6).
) and is discharged through the dust exhaust pipe, and the mixed rice falls directly from the communication chamber (5) into the discharge gutter (4).

As described above, the present invention provides a grain sorting machine in which a spiral conveyor is mounted inside a receiving gutter installed inside a pot-hole type rotary sorting barrel, in which a spiral conveyor is installed in a vertical direction communicating with an end of the receiving gutter. A slightly wider communication chamber is formed at the top of the discharge gutter, and the suction side of the dust suction device is connected to the outside of the communication chamber, so that the dust inside the receiving gutter is sorted by the rotating sorting cylinder. As the grains are being transported out, they fall into the transport gutter, where they are scattered in the communication chamber, and the dust can be effectively sucked up by the dust suction machine. This method has the advantage of being able to reliably and effectively remove dust from grains, and having a simple structure and suitable implementation.
