Description

Technical Field

[0001] The utility model relates to the technical field of coal mine separation, in particular to a cleaning and separation device for coal mines. Background Technique

[0002] With the development of society, coal mines are important resources required for the economic development of our country and have made important contributions to the economic development of our country. However, during the coal mining process, there are often many other impurities mixed with coal blocks. Therefore, it is necessary to clean the coal blocks through a cleaning device to obtain relatively clean coal blocks, which is convenient for use after drying. At present, before the coal blocks enter the cleaning device for cleaning, it is necessary to perform a separation operation on the coal blocks. During separation, the coal blocks are often screened by a vibrating screen.

[0003] The patent with the application number 202320005346.5 discloses a separation device for coal pit mining and cleaning in coal mine production, including a vibrating screen main body. The inner side of the vibrating screen main body is fixedly connected with an upper screen plate. Two first bolts and four second bolts are threadedly penetrated through the upper surface of the upper screen plate. The bottom of the upper screen plate is fixedly connected with two guide plates. A lower screen plate is slidably connected between the two guide plates. Two through first installation grooves are opened at the bottom of the lower screen plate. The bottom ends of adjacent first bolts respectively pass through the first installation grooves and are provided with corresponding nuts. Two connecting plates are fixedly connected to both sides of the lower screen plate. Two through second installation grooves are opened at the bottom of the four connecting plates. The bottom ends of adjacent second bolts respectively pass through the second installation grooves and are provided with corresponding nuts.

[0004] The above solution solves the problems of non-adjustable screen hole diameter in the coal mine separation device and dust flying during the screening process. However, in the above device, the distance between the upper screen plate and the lower screen plate aperture is adjusted through nuts to change the size of the screen holes. However, this adjustment method may be relatively cumbersome and inefficient in actual operation. Each adjustment requires manually tightening or loosening multiple nuts, which not only takes time and effort, but also greatly reduces the work efficiency in the case of frequently needing to adjust the screen hole size.
