The inspection door 7 is convenient for opening the crushing device body 1 for internal inspection and maintenance. When the vibration component 5 is in use, the driving motor 56 drives the rotating shaft 55 to rotate, and the rotation of the rotating shaft 55 drives the push rod 54 to rotate, and the rotation of the push rod 54 drives the support seat 3 to move upward, so that the return rod 53 moves inside the elastic seat 51 to pull The return spring 52 is extended so that the screen 4 can be moved up and down for screening. When in use, the blocking cover 57 is opened, and the crushed unqualified raw coal is allowed to slide into the collecting box 58, the raw coal is collected, and then reprocessed, so that when the device is in use, it is convenient to move the screen 4 up for vibration screening, thereby improving the practicality of use. When the disassembly and assembly component 6 is in use, when it is necessary to replace the screen 4, the push rod 62 is pushed, and the push rod 62 drives the fixed slider 63 to move and compress the fixed spring 64, so that the fixed block 61 is disengaged from the fixed hole, and then the rubber limit block 66 is pushed to move and insert one side of the push rod 62 to limit the push rod 62. Then the screen 4 can be taken out from the supporting seat 3 for replacement, so that when the device is in use, it is convenient to replace the screen 4 with different apertures according to the needs of screening, thereby improving the practicality of use.
