Problems solved by technology

[0002] The publication number is CN111550280A, which discloses the field of coal mine roadway dust removal technology, specifically a movable dust removal and explosion-proof device for coal mine roadway, including a main line pipe, a branch line pipe and a suction head. One side of the main line pipe is connected with several evenly distributed branch lines One end of the branch pipe is connected with a suction head, and the shape of the suction head is a disc shell, one end of which is integrally connected with a square shell. A shaft is movable in the inner cavity of the outer cylinder, and the fixed ring on the outer wall of the outer cylinder is provided with a number of evenly distributed blade plates. Carry out suction work, here can be got final product by adjusting the relative position of propulsion plate and intercepting device, several suction heads do not carry out suction at the same time, need to use the suction of low air pressure in main line pipe, can drive the whole of the present invention, realize Stable and efficient suction work greatly saves energy loss, but the device can only work under the same conditions, and it is not possible to change different dust suction effects for different situations
