[0030] The technical solution provided in this embodiment is as follows: In use, firstly, the mass sensor 12 is zeroed, and simultaneously, the correct installation of the positioning block 15 is checked. Next, the weighed material is placed on top of the upper screening assembly 3. Then, the first motor 21 and the second motor 81 are started. The motors start, causing the rocker arm to rotate. Then, through the driven rod, the two rotating shafts move up and down reciprocally, making the material screening faster. After the material passes through the upper screen 31, it falls into the lower screen 31 and enters the weighing box 9. Materials that do not meet the initial screening requirements will be removed from the upper screen. One side of the square screen 31 falls down and enters the secondary screening stage through the guide plate 13, making the screening more thorough. Materials that meet the requirements will enter the weighing box 9. Materials that do not meet the requirements after two screenings will fall into the collection box 7 through the conveyor plate 6. After screening, the mass sensor 12 will weigh the screened materials and determine the particle size of the crusher by the difference in weight. After weighing, the positioning block 15 is pulled out and the weighing box 9 is taken out. When the particle size requirement is higher or lower, the screen 31 can be replaced.

[0031] Furthermore, the screening component 3 includes a screen 31, a fixed frame 32 and a fixing screw 33.
