The unique structure of the screening box of this technical solution cooperates with the screening plate, so that the screening plate can always fit the inner wall of the screening box when the screening plate is deflected, and no sand leaks; the setting of the deflection drive component can make the screening plate swing left and right and tilt, and the sand and gravel roll back and forth on the screening plate, which can make full use of the screening plate and control the residence time of the sand and gravel on the screening plate at will to fully screen the sand and gravel. There is no need to set up screening plates in multiple layers to extend the residence time or to screen the sand and gravel multiple times to fully screen the sand and gravel, which reduces the complexity of the structure, facilitates maintenance and cleaning, and reduces labor intensity.

[0030] The outer surface of the guide rod 3 is sleeved with a spring 14, one end of the spring 14 is mounted on the inner surface of the slide groove 102, and the other end of the spring 14 is mounted on the lower surface of the slider 201;

[0031] The dust removal assembly 9 includes a water storage tank 901, a cover body 902 is installed on the upper surface of the water storage tank 901, a water outlet pipe 903 is arranged on the upper surface of the cover body 902, a water inlet pipe 904 is arranged at one end of the water storage tank 901, one end of the water outlet pipe 903 and the water inlet pipe 904 both extend to the inside of the water storage tank 901, and the other ends of the water outlet pipe 903 and the water inlet pipe 904 both extend to the inside of the screening box 2, a water pump 905 is installed at one end of the water outlet pipe 903, and a spray plate 906 is installed at the other end of the water outlet pipe 903;

[0032] A water collecting tank 10 is provided inside the screening box 2, a through hole is installed on the outer surface of the water collecting tank 10, and a water inlet pipe 904 is installed inside the through hole;

[0033] A connecting plate 13 is installed on the lower surface of the screening box 2, and a water storage tank 901 is installed on the upper surface of the connecting plate 13;

[0034] Through the coordinated use of the water storage tank 901, the cover 902, the water outlet pipe 903, the water inlet pipe 904, the water pump 905 and the spray plate 906, the dust reduction effect can be achieved inside the screening box 2, which can effectively solve the problem of generating a large amount of dust when screening sand and gravel, which not only pollutes the surrounding air, but also makes it easy for the surrounding workers to be exposed to excessive dust, thereby achieving a better protection effect;

[0035] The lower surface of the water collecting tank 10 is provided with support rods 1001, and the number of support rods 1001 is set to four and evenly distributed;

[0036] Through the coordinated use of the water collecting tank 10 and the filter plate 12, the sprayed water can be recovered, achieving a better environmental protection effect.

[0037] When in use, first separate the cover 902 from the water tank 901, then inject water into the water tank 901, and when the water tank 901 is full, close the cover 902 and the water tank 901, pour sand and gravel into the feed port 202, the sand and gravel first fall onto the first sieve plate 203, and when the particle size of the sand and gravel is smaller than the sieve hole of the first sieve plate 203, it will pass through the sieve hole and fall onto the second sieve plate 204, and by starting the drive motor 5, the output end of the drive motor 5 drives the connecting shaft 4 Rotation, the cam 6 is driven to rotate during the rotation of the connecting shaft 4, so that the cam 6 lifts the screening box 2, and the slider 201 slides upward along the inner axis of the slide groove 102. When the cam 6 lifts the screening box 2, the spring 14 is gradually stretched. When the cam 6 cancels the contact with the screening box 2, the spring 14 restores its elasticity and drives the screening box 2 to move downward quickly for reset. The vibration effect is generated during the repeated reset process, which can accelerate the screening of the first screening plate 203 and the second screening plate 204. During the screening process, a large amount of dust will be generated by the sand and gravel. By starting the water pump 905, the water inside the water storage tank 901 flows into the interior of the spray plate 906 through the outlet pipe 903, and then the sand and gravel inside the screening box 2 are sprayed through the spray plate 906 to avoid the generation of dust. At the same time, a part of the water mixed with dust drips onto the filter plate 12. The filter plate 12 can filter the dust mixed in the water, and the filtered water flows into the interior of the water collecting tank 10. When a certain amount of water is stored in the water collecting tank 10 , water flows back to the water storage tank 901 through the water inlet pipe 904 to complete the water circulation. When the sand and gravel screening is completed, the drive motor 5 and the water pump 905 are turned off, and the baffle 7 is separated from the support frame 207 by pulling the handle 8 upward, so that the screened sand and gravel are discharged through the first discharge port 205 and the second discharge port 206. When the filter plate 12 needs to be cleaned, the pull block 1101 is pulled outward to separate the slide plate 11 from the inside of the screening box 2, thereby facilitating the cleaning of the filter plate 12.
