What is the wind? The wind is a hand-held construction machine that uses compressed air as the power to break hard objects with impact. It consists of a gas distribution mechanism, an impact mechanism, and a brazing material. The impact mechanism is a thick-walled cylinder with an impact hammer that reciprocates along the inner wall of the cylinder. The tail of the crucible is inserted into the front end of the cylinder, and the rear end of the cylinder is equipped with a valve box. Used for demolition and municipal reconstruction.

The working principle of the pneumatic pick is that there are many longitudinal air holes around the cylinder wall, and the spring of the plunger valve is compressed to open the air path. One end of these air holes is equipped with a gas valve, pushing the handle sleeve, and the other end is connected to the cylinder, and the air holes are The length is configured according to the movement requirement of the impact hammer, so as to take in the intake or exhaust, and the plunger valve is in the normally closed state of cutting off the gas path under the action of the coil spring. The impact hammer is regularly reciprocated within the cylinder. When the impact hammer moves forward, the hammer strikes the shank; when the impact hammer moves backward, the gas in the cylinder is enclosed in the valve box to form a flexible cushion layer, and the gas in the cylinder is enclosed in the valve box. After re-alloying, move forward again. The hammer head strikes the shank; when the impact hammer moves backwards, the starting device of the wind shovel is located in the handle sleeve. There is a plunger valve between the air inlet pipe and the gas distribution valve to control the gas path, and the plunger valve is in a normally closed state of cutting off the gas path under the action of the coil spring. When the operation is required to pay attention to the wind operation, the brazing material is pressed against the construction surface, the other end is inserted into the cylinder, the handle sleeve is pushed, the spring of the plunger valve is compressed to open the gas path, and there are many longitudinal directions around the cylinder wall. The air venting valve is automatically equipped with a gas distribution valve, and a gas distribution valve box is arranged at the rear end of the cylinder. The impact hammer is continuously reciprocated to strike the shank and break the construction body.
