Technical Field

[0001] The utility model relates to the technical field of air hammers, in particular to a multifunctional coal bucket air hammer. Background Art

[0002] The coal hopper is a pipe with a diameter that gradually decreases from top to bottom, and its lower end diameter is slightly smaller than the belt width of the conveyor belt. Due to the specific shape of the coal hopper, the viscosity, moisture content, particle size and shape of the raw coal, coal often accumulates in the lumen of the coal hopper, resulting in pipeline blockage. In order to solve the above blockage problem, a pneumatic vibration hammer is often used to vibrate the pipe wall of the coal hopper.

[0003] The pneumatic vibratory hammer essentially uses the cylinder to quickly move the piston rod when the air source is filled, so that the piston rod drives the end hammer head plate to hit the outer tube wall of the coal hopper, so that the coal inside the tube cavity can be freed from agglomeration and fall smoothly.

[0004] However, the pneumatic hammer in the prior art needs to be manually held during use, which not only wastes human resources, but also cannot be used for a long time and has poor use effect.
