DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the device more clear and understandable, the device is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the device, and are not used to limit the device.

[0019] Please refer to Figs. 1-3The utility model provides a technical scheme: a grain particle dust removal bran removing device, including the warehouse body 1, the warehouse body 1 inner chamber top is provided with the conical hopper 4, the conical hopper 4 surface is provided with arc rib 5, the warehouse body 1 top is provided with the feed pipe 3, the feed pipe 3 extends to the conical hopper 4, the warehouse body 1 inner chamber and extends to the conical hopper 4 inside and is provided with the air intake component 8, the warehouse body 1 inner chamber is provided with a plurality of dust absorption cover 6 that can dust absorption conical hopper 4, and a plurality of dust absorption cover 6 form dust absorption component.

[0020] The bottom end of the feed pipe 3 and the top end of the conical hopper 4 form a gap, ensuring that the material can flow onto the arc rib 5.

[0021] The arc rib 5 is used to guide the material after it comes out of the feed pipe 3, ensuring that the material is evenly distributed and can be spread out.

[0022] The conical hopper 4 surface is provided with a plurality of openings, ensuring that the air intake component 8 can blow out of the surface of the conical hopper 4, thereby causing the rice bran to be blown up and sucked out by the dust absorption cover 6.
