High efficient short-wall coal-winning machine

Abstract

The invention relates to a high efficiency short wall coal cutter that includes cut arm, lifting oil cylinder and sliding base frame. The cut arm is made up of cut motor, cut roller and cut reducer. The invention designs the cut arm to portrait swinging, and the cut roller to circular truncated cone. It size of the machine would sharply decrease and the entire structure is small and flexible. It has the advantages of simple structure, light weight, low cost and high efficiency.

Description

technical field [0001] The invention relates to coal mining equipment, in particular to a short-wall coal mining machine used for high-efficiency, safe and mechanized mining of short-wall coal seams, and belongs to the technical field of mining equipment. Background technique [0002] In the existing technology, the structure of the ordinary short-wall shearer is similar to that of the traditional long-wall shearer. Most of them are single-drum, and the fuselage is relatively short. Rotate to achieve the purpose of controlling the position of the drum, and the shearer drum is cylindrical. The minimum body length of the short-wall shearer with the above structure is more than 3 meters. This structural size is not suitable for the coal seam working face with a length of less than 20 meters. Moreover, due to the complex structure and many moving parts, it makes equipment maintenance difficult and costly. High cost and poor reliability. In addition, in order to realize the eff...
