Description

TECHNICAL FIELD

[0001] The utility model relates to coal mine processing device technical field especially relates to a coal mine crushing and screening equipment. BACKGROUND

[0002] The coal mine is the area that human beings exploit coal resources in the coal-rich mining area, and is generally divided into underground coal mine and open coal mine. Through crushing and screening, the coal product with uniform particle size can be obtained, which is beneficial to subsequent transportation, storage and utilization.

[0003] Through the search, the patent with the announcement number CN215087486U discloses a coal mine crushing and screening equipment. The existing coal mine crushing equipment in the market is not perfect in technology. When the equipment is added with coal mine, the coal mine directly falls on the surface of the crushing device. Long-time collision of the crushing device makes the service life of the crushing device shorter, the cost of use is higher, and the large coal mine particles cannot be cleaned out of the outside in time, which causes the failure of the equipment and even damages the equipment, resulting in low efficiency and quality of coal mine crushing. Therefore, by setting the baffle mechanism, the coal mine to be crushed is put into the feeding port at the top of the equipment. The weight of the coal mine extrudes the two baffle plates to rotate downward, so that the baffle extrudes the sleeve rod, causing the extension and retraction of the extension and retraction spring in the sleeve, and protecting the first crushing cylinder and the second crushing cylinder.

[0004] When the above-mentioned crushing and screening equipment is used, the service life of the crushing device can be prolonged. In the traditional technology, after the coal mine is crushed and screened, a part of the large coal mine particles screened out will stay on the surface of the filter plate. The operator needs to take out the screened coal mine from the equipment and re-feed it into the equipment for secondary crushing, which requires shutdown operation, increases the workload of the operator, and reduces the processing efficiency.
