Description

Automatic mining air pick of scarfing cinder Technical Field The utility model relates to the technical field of air picks, in particular to an automatic slag-removing mining air pick. Background The mining air pick is used as an important tool in projects such as mining, tunnel excavation and the like, and the compressed air drives the inner piston to reciprocate, so that crushing operation of hard materials such as rock and the like is realized, and the high efficiency and the reliability of the mining air pick have direct influence on the progress and quality of the projects. In actual mining operations, the continuous impact of the air pick on broken rock can produce a large amount of slag, dust and other debris which are easily attached to the heat dissipation holes, air inlets and other part gaps on the surface of the air pick. The existing slag removal mode of the mining air pick has a plurality of defects. The pneumatic pick with the simple slag removing structure is mainly provided with an independent motor for driving slag removing components, so that the energy consumption and the manufacturing cost of equipment are increased, and the reliability of slag removing functions is poor due to the fact that the motor is easy to damage in a dusty and wet mining environment. Disclosure of utility model The utility model aims to at least solve one of the technical problems in the prior art, and provides an automatic slag-removing mining air pick which can solve the problems that part of air picks with simple slag-removing structures adopt independent motors to drive slag-removing components, so that the energy consumption and the manufacturing cost of equipment are increased, and the reliability of slag-removing functions is poor because motors are damaged easily in a dusty and wet mining environment.
