The pneumatic pick is a handheld tool. The pneumatic pick is composed of a valve 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 end 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 that compress the spring of the plunger valve and connect the air path. One end of these air holes is connected to the air valve push 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 it can take turns. The air intake or exhaust plunger valve is in a normally closed state that cuts off the air path under the action of the coil spring. Make the impact hammer reciprocate regularly in the cylinder. When the impact hammer moves forward, the hammer head strikes the drill tail. When the impact hammer moves backward, the gas in the cylinder is enclosed in the valve box to form a flexible cushion layer. The gas in the cylinder is enclosed in the valve box and needs to be redistributed. Charge forward. When the hammer head strikes the drill tail and 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 of cutting off the air path under the action of the coil spring. When the pneumatic pick is working, hold the pick against the construction surface and the other end is connected to the cylinder. The push handle sleeve compresses the spring of the plunger valve and connects the air path. There are many longitudinal air holes around the cylinder wall. The air distribution valve then automatically distributes air behind the cylinder. The end is equipped with a valve box. The impact hammer is continuously reciprocated to hit the drill tail to break the construction body. Therefore, it is required to be compact and portable.
The pneumatic pick made using mature technology is durable, lightweight, has good performance and is easy to operate.
Pneumatic picks are mainly used for crushing concrete, breaking frozen soil, breaking ice, road trimming, digging pits, trenching, mining soft rocks, coal mining, etc. Replacement accessories can be used for construction operations that require impact, such as loading and unloading track pins. It is more flexible, lightweight and applicable among similar products. It is suitable for all-round work, especially suitable for upward or ascending functions in small working spaces. It is also popular for use as an air shovel.
The pneumatic pick is a hand-held pneumatic tool that uses compressed air to push the piston to reciprocate, causing the pick head to continuously hit. Used for mining, road construction, etc.
