Description

Automatic core-discharging cutting pick

Technical Field

The utility model relates to a mining machines especially relate to an automatic pick of coring.

Background

The cutting pick is a tool used for breaking rocks and dropping coal on a coal cutter, a heading machine and a coal planer for cutting coal rocks in the coal industry. At present, the cutting picks used at home and abroad mainly comprise two types, namely a cutting type cutting pick and a pickaxe-shaped cutting pick, and the common characteristic is that a hard alloy head is embedded in a central hole at the front end of the cutting pick and is embedded and welded on the head of a cutting pick body by adopting a brazing method. In the using process, the hard alloy head is seriously abraded, and the failure mode is as follows: brittle fracture of hard alloy head; secondly, the hard alloy head is abraded; and thirdly, the hard alloy head falls off. Because the cutting teeth are seriously worn, huge waste of hard alloy and steel is caused, and the efficiency of the mining machine and the coal production cost are directly influenced.
