Problems solved by technology
When the end of the piston rod hits the outer pipe wall of the falling coal hopper at high speed, the bracket and accessories are also subjected to a huge impulse reaction, which damages the connecting parts and accessories, especially the welding method of the bracket and the outer pipe of the falling coal hopper If the wall is connected, vibration cracks often appear in the welding part

Embodiment Construction
[0009] Below in conjunction with accompanying drawing, the present invention will be further described.
[0010] Such as figure 1 , figure 2 As shown, the present invention provides a vibrating air hammer, which includes a sleeve 20 sleeved outside the cylinder 10, bolts 30 are arranged on the pipe wall of the coal hopper, and the bolts 30 pass through the flange 40 provided at the front end of the sleeve 20. After connecting with the nut 50, a spring 60 is sheathed on the bolt 30 between the flange 40 and the nut 50, and the elastic deformation of the spring 60 mainly absorbs part of the counter-impact force.
[0011] If the spring 60 is a helical compression spring, the sleeve 100 sleeved on its outer wall can avoid inclusion of impurities on the spring body. As a preferred solution, the spring 60 is a disc spring, because this spring has a large rigidity, a strong shock absorbing capacity, and can bear a large load with a small deformation, so that the cost is greatly re...

The invention relates to solid granular material conveying equipment, in particular to a vibration ramming pneumatic hammer for cleaning blockage of a blanking coal bucket.The vibration ramming pneumatic hammer comprises a sleeve arranged outside an air cylinder in a sleeving mode, a bolt is arranged on the pipe wall of the blanking coal bucket, the bolt penetrates through a flange plate arranged at the front end of the sleeve and then is connected with a nut, and the part, between the flange plate and the nut, of the bolt is sleeved with a spring.Reaction will act on the pneumatic hammer while the vibration ramming pneumatic hammer acts on the blanking coal bucket, at that moment, the vibration ramming pneumatic hammer will play a certain buffering role on the reaction, connection between a pneumatic hammer shell and a protection plate is further protected, the service life of the vibration ramming pneumatic hammer is prolonged, the structure is simple, and overhauling is quick and convenient.
Description
technical field [0001] The invention relates to conveying equipment for solid granular materials, in particular to a vibrating air hammer for unclogging a falling coal hopper. Background technique [0002] The blanking coal hopper is in the shape of a tube whose diameter gradually decreases from top to bottom, and the diameter of the lower end is slightly smaller than the belt width of the conveyor belt. Due to the diversification of forms, it often occurs that coal material accumulates in the lumen of the falling coal hopper, which leads to pipeline blockage. In order to solve the above clogging problem, in the prior art, a vibration unit is often installed on the outer pipe wall of the coal hopper to vibrate the pipe wall of the coal hopper. The vibration unit can be a pneumatic vibratory hammer, which essentially uses a cylinder When the gas source is filled, the piston rod moves quickly, and the end of the piston rod strikes the outer tube wall of the coal hopper for di...
