[0018] Beneficial effects:

[0019] The dustproof device in this invention is used for dust prevention on a belt conveyor. This belt conveyor has two conveying states: one where both the first and second conveyor belts convey material to the third conveyor belt; and the other where the second conveyor belt conveys material to the first conveyor belt. When the first and second conveyor belts convey material to the third conveyor belt, because the first and second conveyor belts are respectively equipped with a first dustproof barrier and a second dustproof barrier at their conveying ends, the material can be blocked as it falls. When the material falls, due to gravity... The material's falling speed increases as it converts energy into kinetic energy. Combined with the third dustproof barrier in the middle, this reduces the pressure between the three dustproof barriers, causing the first and second dustproof barriers to clamp the material. When the second conveyor belt transports material to the first conveyor belt, the material falls between the second and fourth dustproof barriers, further clamping it. Thus, the two dustproof barriers effectively block the material, dissipating its gravitational potential energy and preventing it from rebounding and spreading, thereby suppressing dust generation. This dustproof device improves the dust control effect of the belt conveyor, preventing operators from inhaling dust and ensuring their health. Attached Figure Description

[0031] As Figure 1 shown, the dustproof device is used for dustproof of a belt conveyor, the belt conveyor comprises a first conveying belt 11, a second conveying belt 12 and a third conveying belt 13, the first conveying belt 11 and the second conveying belt 12 are arranged to extend along a first direction, the third conveying belt 13 is arranged to extend along a second direction, the height position of the first conveying belt 11 is arranged between the height position of the second conveying belt 12 and the height position of the third conveying belt 13, the first conveying belt 11 and the second conveying belt 12 can convey materials to the third conveying belt 13, or the second conveying belt 12 can convey materials to the first conveying belt 11, the dustproof device comprises a first dustproof cloth 21, a second dustproof cloth 22, a third dustproof cloth 23 and a fourth dustproof cloth 24, the first dustproof cloth 21 is arranged at the conveying terminal of the first conveying belt 11, the second dustproof cloth 22 is arranged at the conveying terminal of the second conveying belt 12, the third dustproof cloth 23 is arranged on the third conveying belt 13 and located between the first dustproof cloth 21 and the second dustproof cloth 22, the top of the third dustproof cloth 23 is not lower than the second conveying belt 12, and the fourth dustproof cloth 24 is arranged on the first conveying belt 11, and the first dustproof cloth 21 is located between the third dustproof cloth 23 and the fourth dustproof cloth 24.

[0032] The dustproof device in the embodiment is used for dustproof of a belt conveyor, the belt conveyor has two conveying states, one is that the first conveying belt 11 and the second conveying belt 12 convey materials to the third conveying belt 13, and the other is that the second conveying belt 12 conveys materials to the first conveying belt 11, when the first conveying belt 11 and the second conveying belt 12 convey materials to the third conveying belt 13, the first dustproof cloth 21 and the second dustproof cloth 22 are arranged at the conveying terminals of the first conveyor and the second conveyor respectively, so that the materials can be blocked when falling, the falling speed of the materials increases due to the conversion of gravitational potential energy into kinetic energy when the materials fall, the space pressure between the three dustproof cloths can be reduced by combining the third dustproof cloth 23 in the middle, so that the first dustproof cloth 21 and the second dustproof cloth 22 can clamp the materials, when the second conveying belt 12 conveys materials to the first conveying belt 11, the materials fall between the second dustproof cloth 22 and the fourth dustproof cloth 24, so that the second dustproof cloth 22 and the fourth dustproof cloth 24 clamp the materials, thus, the two dustproof cloths can block the materials therebetween to consume the gravitational potential energy, so that the materials do not rebound and diffuse, and the generation of smoke and dust is inhibited. The dustproof device can improve the dustproof effect of the belt conveyor, avoid that the smoke and dust is inhaled by the operators, and ensure the health of the production operators.

[0033] The materials in the embodiment are tobacco particles, which are not described here again.

[0034] Furthermore, the position of the second conveyor belt 12 along the first direction is adjustable so that at least a portion of the second conveyor belt 12 is positioned above the first conveyor belt 11; wherein the top height of the third dustproof cover 23 is adjustable and / or the bottom height of the third dustproof cover 23 is adjustable so that the third dustproof cover 23 can avoid the second conveyor belt 12. Thus, adjusting the position of the second conveyor belt 12 changes the conveying state of the belt conveyor. Simultaneously, when the second conveyor belt 12 approaches and moves above the first conveyor belt 11, the top or bottom of the third dustproof cover 23 is adjusted to avoid obstructing the movement of the second conveyor belt 12, facilitating operation.

[0035] Specifically, such as Figure 2 and Figure 3 As shown, the third dustproof barrier 23 is mounted on the dustproof support 231, which is fixed to the third conveyor belt 13. The dustproof support 231 is equipped with a drive unit 232, and the third dustproof barrier 23 is connected to the output end of the drive unit 232.

Similarly, the first dustproof cloth 21 can also be connected to the driving mechanism, so as to adjust the vertical height of the first dustproof cloth 21 and the second dustproof cloth 22, which is suitable for different falling heights. After the height of the second dustproof cloth 22 is adjusted, the second dustproof cloth 22 does not affect the operation of the first conveying belt 11 when the second conveying belt 12 conveys the material to the first conveying belt 11, so as to ensure the reliable operation of the belt conveyor.

[0042] The embodiment also provides a belt conveyor, which comprises the dustproof device according to any one of the above-mentioned solutions. The belt conveyor has two conveying states. In the first state, the first dustproof cloth 21 and the second dustproof cloth 22 clamp the material in combination with the third dustproof cloth 23 when the dustproof device is used.
