[0036] Working principle of the present invention:

[0037] When the above structure is used, when the sand is poured into the storage box 7, the two baffle plates 17 inside the storage box 7 are in a closed state. At this time, the sand can be stored inside the storage box 7, and the two electric push rods 16 respectively drive the corresponding baffle plates 17 to open each other, so that the sand can be discharged through the gap opened between the two baffle plates 17. The size of the gap opened between the two baffle plates 17 can determine the amount of sand discharged, thereby achieving quantitative discharge of the sand and avoiding a large amount of sand from accumulating on the surface of the screen 1, which affects the screening effect.

[0038] After being quantitatively conveyed, the sand enters the surface of the inclined screen 1 through the support frame 4. At this time, the vibration motor 5 causes the screen 1 to vibrate and uses the screen 1 to screen the sand. The large particles of sand are on the surface of the screen 1 and are discharged through the rectangular groove 14, and the small particles of sand are discharged through the discharge frame 3.

[0039] In order to prevent the sieve holes on the surface of the screen 1 from being blocked by sand, at this time, the driving motor 13 is used to drive the screw rod 8 inside one of the installation slots 9 to rotate, and the screw rod 8 drives the movable frame 11 to slide on the bottom of the screen 1, and at the same time, the other end of the movable frame 11 is located outside the slide rod 10 to slide, and the movement of the movable frame 11 is guided. The movement of the movable frame 11 can drive the brush 12 to brush against the surface of the screen 1, so as to clean the surface of the screen 1, thereby preventing the screen 1 from being blocked by sand and affecting the screening effect of the sand.

[0040] Moreover, when the movable frame 11 drives the brush 12 to brush the sieve holes of the screen 1, it will drive the two sleeves 18 to move, and the sleeve 18 drives the sleeve rod 19 to move, and the sleeve rod 19 drives the movable plate 20 and the cleaning cotton 21 at the bottom of the movable plate 20 to move in contact with the bottom of the inner cavity of the discharge frame 3, so that the sand attached to the inside of the discharge frame 3 can be discharged, avoiding the wet sand from being attached to the inside of the discharge frame 3 and being difficult to discharge, resulting in waste of sand, and the surface of the discharge frame 3 can be cleaned. At the same time, since the discharge frame 3 is inclined, the sleeve rod 19 is used to slide inside the sleeve 18 and the movable block 22 squeezes the reset spring 23. The reset spring 23 is reset after being squeezed, which can ensure that the cleaning cotton 21 is moved in contact with the bottom of the inner cavity of the discharge frame 3, and the sand attached to the inside of the discharge frame 3 can be conveniently discharged.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
