Description
Technical Field
The utility model belongs to the technical field of mine equipment, concretely relates to scraper blade machine is with automatic coal blocking device.
Background
A conveyor which is dragged by a scraper chain and conveys bulk materials in a groove is called a scraper conveyor. The KS scraper conveyor is a bendable scraper conveyor, and adjacent middle grooves of the KS scraper conveyor can be bent in a limited degree in the horizontal plane and the vertical plane. The working face conveyor with the machine body arranged at the intersection of the working face and the haulage roadway in a 90-degree bending mode is called a corner scraper conveyor. In the current coal mining face, the scraper conveyor not only serves to convey coal and materials, but also serves as a running track of a coal mining machine, so that the scraper conveyor becomes an indispensable main device in the modern coal mining process. The scraper conveyor can keep continuous operation, and the production can be normally carried out. Otherwise, the whole coal face will be in a production stop state, so that the whole production is interrupted.
During the daily production of the fully mechanized mining face, the phenomenon of coal overflow from the tail of the scraper often occurs, and a specially-assigned person is required to clean the left coal, so that the labor intensity is high, and after the scraper is pushed forwards, part of the left coal is left on the side face of the tail of the scraper and cannot be cleaned, thereby not only causing the waste of coal resources, but also causing the problem of coal left in a goaf.
