Screening device for coal mine transportation

Abstract

The invention provides a coal mine transportation screening device, and relates to the technical field of coal mine screening, the coal mine transportation screening device comprises a crushing mechanism, the crushing mechanism comprises a crushing box and a crushing assembly arranged in the crushing box, and an exhaust outlet is formed in the upper portion of one side of the crushing box; the screening mechanism is arranged in the crushing box, and the screening mechanism is located below the crushing rollers; the dust hood is fixed to the side wall of the smashing box and communicated with the exhaust outlet, one end of the connecting pipe is communicated with the side, away from the smashing box, of the dust hood, the other end of the connecting pipe is communicated with the air inlet end of the cyclone separator, and the fan is installed at the end, close to the dust hood, of the connecting pipe. Through the arrangement of the cyclone separator, dust in the crushing box is adsorbed, it can be guaranteed that the interior of the crushing box is in a dust-free or low-dust state all the time, dust is effectively prevented from being discharged from the discharging opening, harm of dust to operators is reduced, and meanwhile pollution to the environment can be reduced.

Description

technical field [0001] The present application relates to the field of coal mine screening, in particular, to a coal mine transportation screening device. Background technique [0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig underground tunnels to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate the coal, which is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and related facilities. A coal mine is a reasonable space dug by humans when excavating a geological layer rich in coal, usually including roadways, wells and mining faces. Coal is the most...

Problems solved by technology

[0006] In order to overcome the existing shortcomings, the embodiment of the present application provides a coal mine transportation and screening device, which can solve the problem that the dust generated in the coal mine crushing and screening process is discharged from the discharge port, affecting the health of the workers and polluting the environment. It can effectively deal with the dust generated during crushing and reduce the harm to the health of workers.
