The
air leg rock drill is a kind of hand-held machine. The pneumatic leg drill consists of gas distribution mechanism, impact mechanism and pickaxe. Therefore, it is required that the structure is compact and portable. Air leg rock drill is a kind of pneumatic tool, which is widely used in mining industry and construction industry.
Air leg rock drill is composed of gas distribution mechanism, impact mechanism and pickaxe. The impact mechanism is a thick-walled cylinder with an impact hammer reciprocating along the inner wall of the cylinder. The tail of the pickaxe is inserted into the front end of the cylinder, and the rear end of the cylinder is equipped with a distribution valve box.
In the operation of the
air leg rock drill, the pickaxe is held against the construction surface, and the other end is fed into the cylinder, pushing the handle sleeve, compressing the spring of the plunger valve and connecting with the vent road. There are many longitudinal pores around the cylinder wall, and the distribution valve is automatically distributed, and the rear end of the cylinder is equipped with the distribution valve box. So that the impact hammer reciprocating movement, drill tail, crushing construction body.
