[0038] In this embodiment: By providing the partitions 23, when discharging and treating waste, it can prevent the waste from detaching from the waste discharge plate 14 due to excessive speed and falling into the area where the sieved materials are collected.
[0039] As a technical optimization solution of the present utility model, a pulley 24 is rotatably connected to the inner side of the support slider 205.
[0040] In this embodiment: Through the pulley 24, it can better drive the support slider 205 to slide in the chute 204 and drive the high-pressure atomizing nozzle 206 to move.

[0042] In this embodiment: Through the liquid filling valve 25, it is convenient to supplement the liquid in the liquid storage tank 209.
[0043] Working principle: First, the materials to be screened are put in through the feeding funnel 17 and enter the inside of the sieving box 1. Due to the falling speed, some materials can be sieved through the coarse sieve mesh 5. The motor 12 drives the rotating shaft 10 to drive the vibration cam 11, so that the vibration cam 11 drives the pressure and tension spring 4 of the coarse sieve mesh 5 and the pressure telescopic rod of the fine filter screen 8 back and forth, causing the coarse sieve mesh 5 and the fine filter screen 8 to vibrate and filter the materials on their surfaces. The overall inside of the box is at an inclined angle. Under the action of falling and vibration, the waste residues that cannot pass through the filter screen and the materials that have been filtered are respectively processed and collected through the waste discharge plate 14 and the discharge plate 19. During the working process, the liquid in the liquid storage tank 209 is pumped out by the water pump 208 and sprayed through the high-pressure atomizing nozzle 206. The second electronic telescopic rod 210 drives the support slider 205 to slide and drives the high-pressure atomizing nozzle 206 to move back and forth to reduce dust in different working areas of the sieving box 1. After the operation is completed, the dust reduction frame 2 can be adjusted by the first electronic telescopic rod 202 to detect the high-pressure atomizing nozzle 206 and supplement the liquid storage tank 209 through the liquid filling valve 25.
[0044] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
