Coal mine conveying device with screening function

Abstract

The invention provides a coal mine conveying device with a screening function. The coal mine conveying device comprises a coal vehicle, a draught fan, a storing box, a hose, an air pipe, a bent plate,a screw rod, a supporting seat and a nut, the draught fan and the storing box are mounted on the front end face of the coal vehicle, and the draught fan is assembled on the upper side of the left endface of the storing box; the lower end of the hose is assembled at the bottom end of the interior of the storing box, the upper end of the hose penetrates through the storing box and is mounted on the right side of the lower end face of the air pipe, and the design achieves the function of sucking dust; and the bent plate is arranged on the lower end face of the coal vehicle, the screw rod is assembled on the upper side of the right end face of the bent plate, the screw rod is mounted in the supporting seat, the supporting seat is fixed to the lower end face of the coal vehicle, and the nut is assembled on the left end face of the supporting seat and mounted on the left side of an annular side face of the screw rod. The design achieves the function of clearing coal slag, the coal mine conveying device is easy to operate and good in safety, sucking of the dust is achieved, the coal slag can be conveniently and rapidly cleared, and practicability and reliability are high.

Description

technical field [0001] The invention relates to a coal mine conveying device capable of screening, which belongs to the field of mining equipment. Background technique [0002] Coal mine is a reasonable space for human beings to excavate coal-rich geological layers, usually including roadways, shafts and mining faces, etc. Coal is the most important solid fuel and a kind of combustible organic rock. When the distance from the ground surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. When coal mines are transported, the coal mines are usually loaded in a coal car, and the movement of the coal car is realized by rolling the rollers in the transportation track. And then achieve the purpose of convenient coal transportation. [0003] In the prior art, there are still many deficiencies in the coal mine conveying device that can be screened. It has no dust absorption function, and a large amount ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are still many deficiencies in the coal mine conveying device that can be screened. It has no dust absorption function, and a large amount of dust will be generated during the process of transferring the coal mine to the coal car, thereby reducing the air quality. At the same time, the coal car During the movement, coal slag will fall on the transportation track, resulting in the accumulation of coal slag, causing the track to be uneven, and causing the coal car to move bumpy. Therefore, a coal mine conveying device that can be screened is needed to solve the above problems
