The invention discloses coal mine crushing and screening equipment capable of conveying material intermittently. The coal mine crushing and screening equipment comprises a box body. A moving cavity with an upward opening is formed in the box body, a filtering cavity communicating with the moving cavity is formed in the lower inner wall of the moving cavity, a door plate is hinged to the inner wallof the moving cavity, and a material conveying mechanism for conveying materials intermittently is arranged in the box body. The material conveying mechanism comprises a moving block connected in themoving cavity in a sliding manner, a stretching cavity with a downward opening is formed in the moving block, and a stretching plate is connected in the stretching cavity in a sliding manner. The device is simple in structure, convenient to use, capable of automatically screening coal mines and capable of further crushing the coal mines which do not meet the standard till the machined coal minesmeet the standard. The device can filter coal ash in the coal mines and is provided with a complete dust removal device and a closed conveyor, less-dust operation is achieved, the working environmentis purified, and the health of workers is ensured.
Description
technical field [0001] The invention relates to the field of coal mines, in particular to coal mine crushing and screening equipment for intermittent feeding. Background technique [0002] Coal mines vary in size, and the transportation cost of moving large coal mines is higher, and the materials need to be removed from the site for processing. Small coal mines are more convenient to use and easier to transport. Coal mines are crushed. If they are processed and crushed uniformly, it is not only inefficient, but also not energy-saving enough. Therefore, it is necessary to screen coal mines that meet the standards before crushing, and only need to process oversized coal mines, which saves time and effort; The harsh environment can easily cause "black lung disease", which is not conducive to the health of workers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal mine crushing and screening equipment for inter...
