Description

Movable guide chute for scraper conveyor head Technical Field The utility model relates to the technical field of coal mine transportation equipment, in particular to a movable guide chute for a scraper conveyor head. Background In underground fully-mechanized mining operation of a coal mine, the scraper conveyor bears a key task of transferring raw coal to the self-moving tail of the belt conveyor, and the guide chute is used as an important part of the head of the scraper conveyor, so that the smooth and efficient influence on the raw coal transferring process is great. The performance of the coal mine underground safety production line is directly related to whether the production can be carried out efficiently and orderly, and is an important ring for guaranteeing the underground safety production of the coal mine in terms of raw coal recycling and clean production environment. The movable guide chute for installing the scraper conveyor head is directly related to the underground coal mine efficient and safe production. In the fully mechanized mining face, the scraper conveyor transports raw coal to the self-moving tail of the belt conveyor, the raw coal is thrown and falls on the conveyor belt to be taken away, and due to the reasons that the setting of the guide chute is not tight, serious deformation and the like, the raw coal is scattered outside the conveyor belt and accumulated on the frame of the self-moving tail, even falls on the ground, so that great waste is caused, and cleaning is also very laborious, and mine production is influenced. Disclosure of utility model The utility model aims to solve the problems of great waste caused by the fact that raw coal is scattered outside a conveying belt and accumulated on a frame of a self-moving tail and even falls on the ground due to the fact that a trough is not tightly arranged and is seriously deformed in the prior art.
