Multi-cutter-disk crushing mechanism for rotationally and asway cutting coal rocks under driving of hydraulic cylinder

Abstract

The invention provides a multi-cutter-disk crushing mechanism for rotationally and asway cutting coal rocks under driving of a hydraulic cylinder, belonging to the field of mining equipment. The crushing mechanism for coal rock comprises a box body, a spline shaft, a locating sleeve, a cutter head shaft, a cutter head, an end cover, an internal screw, a threaded piston and so on. The mechanism adopts a multi-cutter-disk structure, feeds the cutter head under driving of the hydraulic cylinder, and cuts coal rocks in a rotationally and asway cutting manner. The mechanism is based on a simple principle, has a reliable structure, is easy to realize, can cut hard rocks, is applicable to mine roadway excavation and rock tunnelling, and has characteristics of high tunnelling efficiency and convenience in maintenance.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a coal and rock crushing mechanism with multiple disk cutters for hydraulic cylinder rotary pendulum cutting. technical background [0002] In the coal industry programmatic document "Several Opinions on Promoting the Healthy Development of the Coal Industry", in the National Coal Industry Science and Technology Conference and in the coal industry structural adjustment policy issued by the National Development and Reform Commission, the development of large-scale coal underground comprehensive coal mining equipment is involved and so on. Tunneling and mining are important production links in coal mine production. The country's policy is: pay equal attention to excavation and excavation first. Rapid excavation of coal mine roadway is a key technical measure for coal mines to ensure high and stable mine production. High-efficiency mechanized excavation is one of the necessary cond...

Problems solved by technology

At present, the working mechanism of the cantilever type partial section roadheader adopts the cutting head configured with multiple picks. From the perspective of cutting performance, it is difficult to satisfy the cutting requirements. f For all-rock roadways above 8, not only the tool wear is very serious, the amount of dust is large, the energy consumption is significantly increased, and the vibration of the machine is intensified. It is very urgent to develop a cantilever type partial section roadheader working mechanism suitable for whole rock roadway
