Problems solved by technology
The current problem is that during the mining operation of the shearer, the raw coal in the cutting part of the spiral drum is often scattered, so that part of the raw coal cannot be loaded into the scraper conveyor and transported out, and this part of the residual coal will directly affect the front conveyor. Move forward, and then affect the normal coal mining and transportation operations, reduce the labor efficiency of workers, and correspondingly increase the production cost of enterprises

The invention discloses an abrasion-resisting coal-retaining plate for a coal cutter and relates to the field of coal mining equipment. The abrasion-resisting coal-retaining plate comprises two slipswhich are arranged in a bilateral symmetry mode. The two slips are provided with brackets correspondingly, and the two brackets are symmetrically arranged. The lower ends of the two brackets are jointly and fixedly connected with a coal-retaining plate body. Fixing blocks are arranged at the lower ends of the brackets, mounting grooves corresponding to the fixing blocks are formed in the coal-retaining plate body, and the fixing blocks are fixed into the mounting grooves through screws. An abrasion-resisting layer is further smeared on the outer surface of the coal-retaining plate body. The abrasion resistance of the coal-retaining plate is improved, and thus the life of the coal-retaining plate is prolonged.
Description
technical field [0001] The invention relates to the field of coal mining equipment, in particular to a wear-resistant coal retaining plate for a coal shearer. Background technique [0002] In the process of raw coal mining, due to the influence of geological conditions, coal seam thickness and other factors, it is usually necessary to use small shearers for mining operations. The current problem is that during the mining operation of the shearer, the raw coal in the cutting part of the spiral drum is often scattered, so that part of the raw coal cannot be loaded into the scraper conveyor and transported out, and this part of the residual coal will directly affect the front conveyor. Move forward, and then affect the normal coal mining and transportation operations, reduce the labor efficiency of workers, and correspondingly increase the production cost of enterprises. [0003] At present, although some coal shearers are equipped with coal baffles, it is found during use tha...
