In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a tunnel cleaning device for working face in pit, includes support body, actuating mechanism, insertion plate mechanism and keeps off the coal board, the support body rear is provided with scrapes trigger coupling mechanism, one side is the medial surface for lateral surface, opposite side on the left and right sides direction of support body, actuating mechanism installs in the support body, the actuating mechanism drive insertion plate mechanism is along fore-and-aft direction reciprocating motion, insertion plate mechanism front end is provided with plough board, plough board by lateral surface the place ahead of support body is towards medial surface rear slope, it sets up to keep off the coal board the medial surface top of support body.

Based on the above, the support body is the box structure, the support body corresponds the spout has been seted up to the picture peg mechanism.

Based on the above, the scraper conveyor connecting mechanism is a connecting lug plate.

Based on the above, the driving mechanism comprises an oil cylinder mechanism and a high-pressure rubber pipe for supplying liquid to the oil cylinder mechanism, and the high-pressure rubber pipe is provided with an operating valve group.

Based on the above, the oil cylinder mechanism comprises two oil cylinders which are arranged on the left and the right.

Based on the above, keep off the coal board and be to the sunken arc of support body lateral surface.

Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and particularly, when the invention is used, the roadway cleaning devices are respectively arranged at the head and the tail of the scraper conveyor, and the plow-shaped plate faces forwards, the outer side surface of the frame body faces the end part of the scraper conveyor, and the inner side surface of the frame body faces the middle of the scraper conveyor, so that the inclined surface of the plow-shaped plate faces the coal wall, and the coal baffle plate is positioned at one side of the coal wall; when the scraper conveyor is pushed forwards, the driving mechanism drives the plate inserting mechanism to extend out, the plough plate can extrude fallen coal and gangue in a roadway between a coal wall and a coal blocking plate, when the coal mining machine runs to the position, all the materials are loaded into the scraper conveyor, the situations of excessive material accumulation and difficult pushing in the roadway exist in use, the plate inserting mechanism can be operated to impact the materials in front, and pushing operation can be carried out after loosening.

Furthermore, the frame body is designed into a box body structure, and the sliding groove is formed in the frame body and matched with the plate inserting mechanism, so that sundries can be prevented from entering the frame body, and the pushing smoothness is guaranteed; the driving mechanism adopts a left oil cylinder and a right oil cylinder, so that the pushing stability can be improved, and the operation valve group is convenient to operate the oil cylinders; will the coal blocking plate sets up to the sunken arc of support body lateral surface can gather together the material better to scraper conveyor centre.
