Before the
pneumatic pavement breaker is used, it is necessary to lubricate the pneumatic road crusher. When using pneumatic pavement breaker, there are no less than 3 spare pneumatic road crushers, and the continuous working time of each pneumatic road crusher shall not exceed 2.5h. During operation, hold the handle of the pickaxe and press it in the gouge direction to make the pickaxe abut the sleeve. In the pneumatic road crusher, do not insert all the picks into the broken objects to prevent air strikes.
The
pneumatic pavement breaker is composed of an air distribution mechanism, an impact mechanism and a pick drill. The impact mechanism is a thick-walled cylinder with an impact hammer that can reciprocate along the inner wall of the cylinder. The tail of the pick is inserted into the front end of the cylinder, and the rear end of the cylinder is equipped with a valve box. There are many longitudinal air holes around the cylinder wall, which compress the spring of the plunger valve to connect the air path. One end of these air holes is equipped with an air valve, which pushes the handle sleeve, and the other end leads to the cylinder. The length of each air hole is based on the impact hammer. Movement requires configuration to take turns to intake or exhaust, the plunger valve is in a normally closed state that cuts off the gas path under the action of the coil spring
Pneumatic pavement breaker is a hand-held pneumatic tool. Pneumatic pavement breaker is a crushing tool powered by compressed air, which can efficiently complete the crushing work of reinforced concrete, rock, asphalt, etc. It is lightweight, durable, fast and efficient, and is used for the construction of mines, bridges, roads, water and electricity pipe networks The ideal tool for emergency repair and removal.
