Detailed implementation manners

[0018] Next, refer to the attached Figures 1 - 5 to describe the preferred implementation manners of the present utility model. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0019] The present utility model provides a dust removal mechanism for a coal gangue crusher. When using this device, the cover body 5 of this device is installed on the top of the crushing box, an external vacuum cleaner is connected to the air outlet end of the air outlet pipe 1, one end of the water pipe 3 is connected to an external water pump. When crushing coal gangue, the motor 4, the external water pump and the external vacuum cleaner are started. The water in the water pump is conveyed through the water pipe, the rotary joint and the rotating rod 10 into the water outlet pipe 11, and the water in the water outlet pipe 11 is sprayed out through a group of atomizing nozzles to generate water mist. The vacuum cleaner starts to suck out the dust and large debris generated during the crushing in the crushing box. The motor 4 drives the bevel gear I 13 to rotate, and the bevel gear I 13 drives the engaged bevel gear II 12 and bevel gear III 14 to rotate in opposite directions. The bevel gear II 12 drives the lower end of the rotary joint to rotate, and the rotary joint drives the rotating pipe 10 to rotate along the sleeve 9. The rotating pipe 10 drives the water outlet pipe 11 to rotate, and the water outlet pipe 11 drives a group of atomizing nozzles to rotate. A group of rotating atomizing nozzles spray water mist comprehensively. The water mist reduces the rise of fine dust. At the same time, the bevel gear III 14 drives the sleeve 9 and the rotating pipe 10 to rotate in the opposite direction. The bevel gear III 14 drives a pair of brush rods 15 to rotate along the filter screen of the filter disc 8. The brushes of the pair of brush rods 15 rotate to brush off the large debris attached to the filter screen, preventing the large debris from blocking the filter screen and affecting the exhaust. With the cooperation of the atomizing nozzles and the filter disc 8, fine dust and large debris are respectively filtered and dust removed, achieving the purpose of dust removal, avoiding dust from spreading into the air and polluting the environment, and at the same time avoiding the harm to the physical health of the operator after the dust is inhaled by the operator. After the crushing is completed, this device continues to run for 5 - 10 minutes before being shut down, to avoid the residual dust in the crushing box from floating out.
