　　B47 mining pneumatic pick, B47 pneumatic pick, mining crusher, working principle of pneumatic pick B47

　　B47 pneumatic pick is a tool powered by compressed air, which is distributed to both ends of the cylinder body by a cutting wheel. The hammer undergoes reciprocating motion and impacts the tail of the steel chisel through a cushion hammer, chiseling the steel chisel into the concrete layer and splitting it into blocks. It has significant characteristics such as low vibration, fast crushing speed, safe use, and flexible operation.

　　1、 Working principle of B47 pneumatic pick

　　There are many longitudinal air holes around the cylinder wall, which are connected to the ventilation path by compressing the spring of the plunger valve. One end of these air holes is connected to the 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 punch, so as to alternate intake or exhaust. The plunger valve is in a normally closed state by cutting off the air path under the action of the coil spring. Make the punch move back and forth in the cylinder in a regular manner. When moving forward, the hammer strikes the tail of the drill; When moving backwards, the gas inside the cylinder is enclosed in the valve box, forming a flexible cushion layer. The gas inside the cylinder is enclosed in the valve box and will impact forward after being re supplied. Hammer strikes the tail of the drill; When moving backwards, the starting device of the pneumatic pick is located inside the handle sleeve. There is a plunger valve between the intake duct and the distribution valve to control the air path, and the plunger valve is in a normally closed state to cut off the air path under the action of the coil spring. During the operation of the pneumatic pick, the pick rod is pressed against the construction surface, and the other end is connected to the cylinder. The handle sleeve is pushed to compress the spring of the plunger valve and connect to the ventilation path. There are many longitudinal air holes around the cylinder wall, and the air distribution valve is automatically distributed. The rear end of the cylinder is equipped with an air distribution valve box. Continuously reciprocating the punch to strike the tail of the drill and break the construction body. A pneumatic pick is a handheld tool composed of a pneumatic mechanism, an impact mechanism, and a pick chisel. Therefore, a compact structure and lightweight portability are required.

　　3、 Precautions for using B47 pickaxe:

　　1. Before using the pneumatic pick, it is necessary to lubricate it with oil.

　　2. When using wind picks, there should be no less than 3 spare wind picks, and each wind pick should not work continuously for more than 2.5 hours.

　　3. During operation, hold the handle of the pickaxe and press it tightly in the direction of the chisel, so that the pickaxe tool is firmly pressed against the tool sleeve.

　　4. The inner diameter of the selected trachea should be 16mm, with a length not exceeding 12m, and ensure that the inside of the trachea is clean and the tracheal joint is firmly and reliably connected.

　　5. When operating, do not insert all the picks and drills into the broken object to prevent air strikes.

　　6. When the chisel is stuck in the titanium lump, do not shake the air hammer forcefully to avoid damage to the body.

　　7. When operating, choose the appropriate pick and chisel, and select different pick and chisel according to the hardness of the titanium lump. The harder the titanium lump, the shorter the pick and chisel. Also, pay attention to checking the heating situation at the tail of the chisel to prevent it from getting stuck.

　　8. When using a pickaxe to drill the rough edge, it should be dealt with in a timely manner and the rough edge pickaxe should not be used for operation.

　　9. Empty strikes are strictly prohibited.
