Pneumatic pavement breaker is a hand-held implement, so pneumatic pavement breaker needs to be compact and portable. Pneumatic road crusher is a hand-held construction machine that uses compressed air as power and uses impact to break hard objects. Pneumatic pavement breaker are often used in excavation engineering, road engineering and other construction projects. Pneumatic road crusher is composed of gas distribution mechanism, impact mechanism and pick braze. The impact mechanism is a thick-walled cylinder with an impact hammer that can reciprocate along the cylinder's inner wall.
The tail end of the pick of the
pneumatic pavement breaker 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. These air holes are equipped with an air valve at one end and into the cylinder at the other end. The length of each air hole is configured according to the movement requirements of the impact hammer, so as to take turns in or out of the air, so that the impact hammer is in the cylinder Reciprocate regularly. When the impact hammer moves forward, the hammer head hits the brazing tail; when the impact hammer moves backward, the gas in the cylinder is enclosed in the valve box to form a flexible cushion layer, and then it will impact forward after re-distribution.
The starting device of the pneumatic pavement breaker is located in the handle sleeve. A plunger valve controls the air path between the air inlet pipe and the gas distribution valve. The plunger valve is in the normally closed state of cutting off the air path under the action of the coil spring. When the pneumatic road crusher is in operation, the pick brace is pressed against the construction surface, the handle sleeve is pressed, the spring of the plunger valve is compressed to connect the gas path, and the gas distribution valve automatically distributes the gas immediately, so that the impact hammer continuously reciprocates and strikes the brace. Tail, broken construction body.
