[0033] Please refer to Figures 1-6The utility model provides a technical scheme: a dust cover for mine operation, including dust suction box 1, dust suction box 1 is oval, the bottom fixed connection of dust suction box 1 has dust suction pipe 5, the bottom of dust suction pipe 5 is provided with dust cover 7;

[0034] The suction fan 2 is fixedly connected to the dust suction box 1, and the box door 8 is arranged on the dust suction box 1.

[0035] The filter core 3 is fixedly connected to the inner top surface of the dust suction box 1, and the filter core 3 is located below the suction fan 2.

[0036] The dust cover 7 is in the shape of a horn, and the dust cover 7 is composed of four dust suction plates in the shape of a quarter of a horn.

[0037] When dust suction is needed, the dust cover 7 can be arranged at the position where dust suction is needed, and at this time, the suction fan 2 is started, the air in the dust suction box 1 is quickly discharged, so that the inside of the dust suction box 1 is in a negative pressure state, at this time, the air carrying dust from the outside enters the inside of the dust suction box 1 through the dust cover 7 and the dust suction pipe 5, and is intercepted in the inside of the dust suction box 1 by the filter core 3, so that the dust suction work is completed.

[0038] The side, away from the filter core 3, of the flow guide plate 4 is an inclined surface.

[0039] The side, away from the filter core 3, of the flow guide plate 4 is an inclined surface, so that the effect of guiding dust is achieved, the dust can enter the inside of the dust suction box 1 better, and the dust is prevented from falling out through the dust suction pipe 5 after the suction fan 2 stops working.

[0040] Further, the adjusting mechanism includes a threaded rod 6, and the threaded rod 6 is rotationally connected to the inner wall of the dust suction pipe 5.

[0041] The threaded rod 6 is opposite in thread at both ends starting from the center position, and the front and rear two corresponding dust suction plates are rotationally connected to the positive and negative threads of the threaded rod 6.

[0042] Two lead screws 11 are rotationally connected to the inner wall of the dust suction pipe 5, and the left and right two dust suction plates are respectively threadedly connected with the lead screws 11.

[0043] The first bevel gear 10 is fixedly connected to the threaded rod 6, the second bevel gear 12 is fixedly connected to the two lead screws 11 respectively, and the first bevel gear 10 and the second bevel gear 12 are meshingly connected.

[0044] When it is necessary to adjust the area of the dust suction cover 7, only the threaded rod 6 needs to be rotated, the rotation of the threaded rod 6 causes the front and rear dust suction plates to move towards or away from each other, and the first bevel gear 10 drives the rotation of the lead screw 11 through the meshing with the second bevel gear 12, so that the left and right dust suction plates move towards or away from each other at the same time, when the dust suction plates move towards each other, the area of the dust suction cover 7 is reduced, and when the dust suction plates move away from each other, the area of the dust suction cover 7 is increased, thus adapting to different dust suction environments;

[0045] Further, the inside of the dust suction pipe 5 is fixedly connected with a blocking ring 9, and the top of the dust suction plate is attached to the bottom of the blocking ring 9;

[0046] By setting the blocking ring 9, the dust suction plate is limited in rotation and only slides during the rotation of the lead screw 11 or the threaded rod 6;

[0047] Further, one side of the dust suction plate is provided with a receiving groove 14, and the inside of the receiving groove 14 is rotatably connected with a receiving shaft 15, and the receiving shaft 15 is provided with a clock spring 16;

[0048] The dust cloth 13 is fixedly connected to the receiving shaft 15, and the other end of the dust cloth 13 is fixedly connected to the adjacent dust suction plate;

[0049] The two ends of the clock spring 16 are fixedly connected to the inner wall of the receiving groove 14 and the surface of the receiving shaft 15, respectively;

[0050] By setting the dust cloth 13, when the dust suction plates move away from each other, the dust cloth 13 is stretched and loosened from the receiving shaft 15 due to the movement of the dust suction plates, thus sealing the gap between the two adjacent dust suction plates, and thus ensuring the dust suction effect of the dust suction cover 7, and when the dust suction plates move towards each other, the dust cloth 13 is rewound on the receiving shaft 15 by the elasticity of the clock spring 16.

[0051] Working principle: when it is necessary to adjust the area of the dust suction cover 7, only the threaded rod 6 needs to be rotated, the rotation of the threaded rod 6 causes the front and rear dust suction plates to move towards or away from each other, and the first bevel gear 10 drives the rotation of the lead screw 11 through the meshing with the second bevel gear 12, so that the left and right dust suction plates move towards or away from each other at the same time, when the dust suction plates move towards each other, the area of the dust suction cover 7 is reduced, and when the dust suction plates move away from each other, the area of the dust suction cover 7 is increased, thus adapting to different dust suction environments;

[0052] By setting the dust cloth 13, therefore, when the dust absorption plates move away from each other, the dust cloth 13 is stretched and loosened from the storage shaft 15 along with the movement of the dust absorption plates, thus sealing the gap between the two adjacent dust absorption plates and ensuring the dust absorption effect of the dust absorption cover 7. When the dust absorption plates move towards each other, the dust cloth 13 is rewound on the storage shaft 15 by the elasticity of the clockwork spring 16.

[0053] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art in the technical field without departing from the purpose of the utility model.
