Small crushing equipment--Pneumatic Pick Hammer

Pneumatic Pick Hamme (pneumatic breaker ) is a handheld construction tool that uses compressed air as power to crush hard objects by impact. It is a handheld tool, so it requires a compact structure and is easy to carry.

The pick is an important part of the pneumatic pick, and is where the pneumatic pick contacts the surface of the object to be crushed.

The picture shows a worker using a pneumatic pick to remove part of the concrete at the head of the cast-in-place pile. The length of the cast-in-place pile needs to be increased by 0.25m, which needs to be removed.

After using it for a period of time, the end of the pick will become blunt. According to the worker, the blunt and soft pick cannot be polished by machine, but can only be forged by fire. The pick is heated with carbon on site until it turns red. The end of the steel pipe below is the blower.

The power supply device for the pneumatic pick is an air compressor. Small compressors generally cost only a few thousand yuan, and large ones cost tens of thousands of yuan.

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 connected to the gas distribution valve, pushing the handle sleeve, and the other end is connected to the cylinder. The length of each air hole is configured according to the movement requirements of the impact hammer so that air can be taken in or out in turn. The plunger valve is in a normally closed state of cutting off the air path under the action of the spiral spring. Make the impact hammer reciprocate regularly in the cylinder. When the impact hammer moves forward, the hammer head hits the drill tail; when the impact hammer moves backward, the gas in the cylinder is sealed in the gas distribution valve box to form a flexible buffer layer, and the gas in the cylinder is sealed in the gas distribution valve box, and it will impact forward after re-distribution. The hammer head hits the drill tail; when the impact hammer moves backward, the starting device of the pneumatic pick is located in the handle sleeve. There is a plunger valve between the air inlet pipe and the air distribution valve to control the air path. The plunger valve is in a normally closed state to cut off the air path under the action of the spiral spring. When the pneumatic pick is in operation, the pick is pressed against the construction surface, and the other end is passed into the cylinder. The handle sleeve is pushed to compress the spring of the plunger valve to connect the air path. There are many longitudinal air holes around the cylinder wall, and the air distribution valve automatically distributes air. The rear end of the cylinder is equipped with an air distribution valve box. The impact hammer is constantly reciprocating to hit the tail of the pick and break the construction body. The pneumatic pick is a handheld machine, which consists of an air distribution mechanism, an impact mechanism, and a pick. Therefore, it is required to be compact and portable.
