Description

[Detailed description of the invention] The present invention relates to an improvement of a dust collection device for a grain sorting machine for removing stones.

The dust collection device of conventional grain sorting machines prevents dust-containing air such as bran powder ejected from the blower onto the porous wall sorting board from scattering outside the machine through the opening of the machine, or falling under its own weight and collapsing into the machine. In addition, dust accumulates on the operating parts, causing pests to appear, emitting strange odors, deteriorating the working environment, and causing malfunctions in the operating parts. 6. Sorting performance is reduced due to adhesion. In addition, foreign substances were deposited at the sand grain outlet, which obstructed the discharge of the sand grains.

・The present invention provides a sorting air passage in the sorting frame and connects it to the air outlet, so that the mixed grain is separated from impurities, dust, etc. by the sorting air passage, and the carefully selected soil and sand mixed grain is placed on the sorting board. To provide a device that prevents dust from accumulating or adhering to the inside of the machine, a sorting board, etc., since grains can be supplied.

The present invention will be explained with reference to embodiment figures. Reference numeral (1) indicates a perforated wall sorting machine, and the side of the plate (1) is almost hermetically surrounded by a screen wall to form a sorting air passage (8) to form a sorting frame (2). A wind turbine (5) that blows air to the sorting board (1) is installed in the lower part of the frame (2), and a running wind turbine box (4) is installed, and the wind turbine box (4) is equipped with a vibration device (6) and a supporting rod. (7) (
7), the device is configured to swing diagonally up and down, and this device has a supply hopper (9) at the top and a box-shaped machine frame (8) with an air intake port (10) at the bottom. It is installed inside the. The sorting frame (2) is provided with a dirt grain discharge port (11) protruding from its rocking side, a grain discharge port (12) from its rocking side, and an opening (18) at the top 111thi. It is arranged so as to face the supply hopper (9) provided in the machine frame (8). In addition, (14) is an exhaust port,
The air exhaust port (14) is provided in the direction of the wind turbine (5) and on the grain outlet (12) side of the sorting frame (2).
At the same time, the front 11t3 exhaust port (14) is extended to the outside of the oak frame (8), and a dust collection filter (15) is removably attached using a stopper. In addition,
The exhaust port (14) may be provided at any im* of the sorting frame (2). (16) is a dispersion plate installed in the sorting frame (2) at the bottom of the supply hopper (9), (17) is the air supply port of the wind turbine box, (18) is the drive motor, and (19) supports the filter. It is a support rod.

In the above configuration, the former consort funeral board (1
)■The mixed grains of soil and sand supplied above are fed fresh outside air from the air intake port (10) to the air supply port (17). Windmill through (6)
The light grains are floated by the wind blowing from the top and discharged from the grain discharge port (12) on the low side.
1).

Then, the mixed grains are sorted through a distribution plate (16) equipped with a sorting air passage (8).
), and when the contaminants, dust, etc. are sorted out by the sorting air passage (8) and then collected from the air outlet (14) provided in the wind direction of the wind turbine. The filtered air is collected in the back filter and released outside the filter.

In short, the present invention has a structure in which the sides of a porous wall sorting board are almost hermetically surrounded by a screen wall to form a sorting air path, and the KL7 is connected to an air outlet to collect foreign matter, dust, etc.
From t, 7 the machine frame is always clean without being filled with dust-laden air 9, and not only does it not require cleaning of each operating part, etc.
No breakdowns occur. In addition, impurities, bran, etc. in the mixed grains fed onto the sorting board are air-separated in the sorting air path, so the soil grain outlet is not clogged with impurities, and grains are also sorted out. This is due to its effectiveness in maintaining a sorting function with 1111 accuracy because no bran powder or the like adheres to the board.
