[0033] In the present embodiment, in order to achieve the rapid screening effect of sand and gravel, a primary screening component 3 is designed, a rectangular opening 3-1 is opened on the surface of the frame 1, two cross bars 3-2 are arranged inside, the outer sliding sleeve of the cross bar 3-2 is connected with a movable frame 3-3 that moves left and right, and two rear frames 3-4 are arranged on the back of the movable frame 3-3, a cam 3-5 is arranged at the output end of the driving motor 2, the cam 3-5 is located between the rear frames 3-4, the output end of the driving motor 2 can drive the cam 3-5 to rotate, and the rear frames 3-4 can be repeatedly pushed left and right during the rotation process, so that the first-stage screen bucket 3-6 can be quickly shaken left and right to speed up the screening speed, a telescopic cylinder 3-8 is connected between the movable frame 3-3 and the first-stage screen bucket through a connecting block 3-7, the first-stage screen bucket 3-6 can be pushed upward by the telescopic cylinder 3-8, the first-stage screen bucket 3-6 can be turned up through the pin connection, the unfiltered sand and gravel can be discharged outward at an inclined angle, and the inclined baffle 3-9 can block the discharged sand and gravel.

[0034] Furthermore, the secondary screening assembly 4 includes a collecting hopper 4-1, which is fixed on the side surface of the frame 1, and a secondary sieve plate 4-2 is installed in the collecting hopper 4-1, and the secondary sieve plate 4-2 is connected in an inclined state. A discharge port 4-3 is provided on the side surface of the collecting hopper 4-1, and the lowest point of the secondary sieve plate 4-2 is located below the discharge port 4-3. A cover plate 4-4 is rotatably connected to the discharge port 4-3 through a pin shaft, and an extension frame 4-5 is provided on the side end surface of the collecting hopper 4-1, and a second cylinder 4-6 is rotatably connected to the extension frame 4-5 and the cover plate 4-4 through a pin shaft.

[0035] In this embodiment, in order to achieve the effect of secondary screening of sand and gravel, a secondary screening component 4 is designed. A collecting hopper 4-1 is fixedly connected to the surface of the frame 1, and a secondary screen plate 4-2 with an inclined structure is arranged inside. The scattered sand and gravel can be quickly screened by the secondary screen plate 4-2 with an inclined angle, and the unfiltered sand and gravel can be concentrated at the lowest point through the inclined angle. A cover plate 4-4 is rotatably connected in the discharge port 4-3, and a second cylinder 4-6 is connected between the cover plate 4-4 and the collecting hopper 4-1. The switch of the cover plate 4-4 can be controlled by the second cylinder 4-6, and the unfiltered sand and gravel can be discharged outward after opening.

A collecting box 5-2 with moving wheels 5-3 is placed in the correction port 5-1. The size of the bottom of the collecting box 5-2 is the same as the internal spacing of the correction port 5-1. When the collecting box 5-2 moves into the correction port 5-1, it can be directly below the collecting hopper 4-1.

[0038] Furthermore, the opening size of the first-stage sieve bucket 3-6 is larger than the opening size of the second-stage sieve plate 4-2.

[0039] In this embodiment, different opening sizes are used to allow the first-stage screen bucket 3-6 and the second-stage screen plate 4-2 to screen out sand and gravel of different sizes, thereby achieving a multi-stage screening effect.

[0040] Furthermore, the movable frame 3 - 3 is a hollow outer frame structure as a whole.

[0041] In this embodiment, the hollow frame structure is used to avoid the hollow part of the movable frame 3-3 from being directly below the primary screen bucket 3-6, so as to avoid hindering the falling of sand and gravel.

[0042] Furthermore, an arc-shaped groove 6 is opened on the side surface of the rear frame 3-4, and the opening size of the arc-shaped groove 6 is the same as the thickness size of the cam 3-5.

[0043] In this embodiment, by opening an arc groove 6 on the side surface of the rear frame 3-4, the contact and sliding of the rear frame 3-4 and the cam 3-5 through the arc groove 6 are smoother, thereby improving the transmission stability.

[0044] When screening is needed, sand and gravel are put into the first-level screen bucket 3-6 at the top, and the driving motor 2 is started. The cam 3-5 rotates in the arc groove 6 to repeatedly push the rear frame 3-4 left and right, so that the first-level screen bucket 3-6 swings back and forth on the surface of the cross bar 3-2 to speed up the screening speed. The screened sand and gravel fall directly into the collecting hopper 4-1, and the sand and gravel are screened for the second level through the inclined secondary screen plate 4-2. The final material falls directly into the collecting box 5-2, and the collecting box 5-2 can be directly pushed away by the moving wheel 5-3 and replaced with an empty one. After a certain amount of sand and gravel accumulates in the first-level screen bucket 3-6, the telescopic cylinder 3-8 can be started to push the output end of the first-level screen bucket 3-6 upward, and the sand and gravel are slid outward through the tilt angle. When cleaning the secondary screen plate 4-2, the second cylinder 4-6 is started, and the output end contracts to pull the cover plate 4-4, and the discharge port 4-3 is opened to discharge the sand and gravel outward.

[0045] The above are only preferred embodiments of the present invention and are 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.
