Description

Technical Field

[0001] The utility model relates to the technical field of coal washing and sorting, in particular to a coal washing auxiliary sorting device. Background Art

[0002] Usually, after coal mining is completed, a coal washing process is required. Coal washing is an industrial process to remove impurities from raw coal or to classify high-quality coal and low-quality coal. Then, a vibrating screen is used to sort and screen the coal blocks. The current linear vibrating screen is not convenient for secondary screening of coal blocks after screening, which leads to poor screening effect of coal blocks. If the coal blocks are screened for the second time, the screened coal blocks need to be taken out and then put back on the vibrating screen, which is laborious and troublesome.

[0003] To this end, the utility model patent with publication number CN218982303U discloses a linear vibrating screen for coal washing and sorting, including a body, a base, springs are arranged around the top of the base, the tops of the springs are connected to the bottom plate, a vibration motor is arranged at the bottom of the bottom plate, side plates are arranged at the front and rear ends of the top of the bottom plate, and the opposite sides of the two sets of side plates are connected to the screen plate; a pushing assembly includes two sets of driving devices with the same structure, the driving device drives the bracket to slide on the side plate, so that the push plate can slide on the screen plate, so that after the coal block is screened once, the coal block can be pushed to the right end of the screen plate again for re-screening, and the whole process is labor-saving and convenient;

[0004] However, in actual operation, we found that when the above-mentioned device is in use, the push plate can slide on the screen plate, so that after one screening is completed, the coal block can be pushed back to the right end of the screen plate for re-screening. For this operation, the push plate part needs to travel a long distance, and the screening situation cannot be accurately known. The overall time consumption is relatively long, resulting in reduced overall efficiency. Utility Model Content
