[0034] The working principle of this utility model:

[0035] First, the staff places the utility model at the position where sand screening is required, and then places the collecting box 25 inside the screening box 1 through the opening 15, and then adds the sand and gravel that need to be screened into the mixing box 3 through the top of the mixing box 3, and starts the mixing motor 4 to drive the mixing shaft 5 and the mixing blade 6 to rotate to mix the sand and gravel. After preliminary mixing, the dispersion of the sand and gravel is improved, which is convenient for subsequent screening. The sand and gravel after mixing will fall onto the screen 7, and at the same time, the auxiliary inclined block 24 can better collect the sand and gravel that fall from the mixing box 3 onto the screen 7. At this time, the sand and gravel on the screen 7 will Accumulation. Based on the existing technology, the accumulated sand and gravel can only be slowly spread out under the vibration of the screen 7, resulting in low screening efficiency. In the utility model, the mobile motor 16 can be turned on, and the mobile motor 16 drives the first screw 17 to rotate. The rotation of the first screw 17 will drive the moving plate 18 to move on the first screw 17, thereby realizing the spreading of the accumulated sand and gravel. Moreover, the reciprocating rotation of the mobile motor 16 drives the moving plate 18 to move back and forth, thereby continuously spreading the accumulated sand and gravel, and the spread sand and gravel are screened through the screen 7, thereby improving the screening efficiency. When the screen 7 needs to be vibrated, the rotating motor 8 can be turned on, which drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the eccentric wheel 10 to rotate. Because the screen 7 will compress the spring 13 along the auxiliary column 14 under the action of the gravity of the sand and gravel, the position of the screen 7 will move downward compared to the initial position. At this time, the rotation of the eccentric wheel 10 will push the screen 7 to move up and down, thereby completing the screening of the sand and gravel. After the screening of the sand and gravel is completed, the movable plate 18 can be moved to a position convenient for the staff to operate by the movable motor 16, and then the rotating handle 19 is rotated. The rotation of the rotating handle 19 drives the second screw 20 to rotate, and the rotation of the second screw 20 drives the cleaning plate 21 to move downward, and the cleaning plate 21 drives the cleaning brush 22 to move downward. After the cleaning brush 22 moves downward, the surface of the screen 7 is cleaned under the drive of the movable motor 16 to reduce the blockage of the screen 7, and the cleaning plate 21 and the cleaning brush 22 can be retracted into the movable plate 18 when not in use, and will not cause obstruction to the movable plate 18 and the sand and gravel when the movable plate 18 spreads the sand and gravel.
