The inner wall of the bearing 9 is movably and rotatably connected to the outer surface of the connecting shaft 6, and the outer surface of the bearing 9 is fixedly connected to the inner wall of the positioning shell 10. The connecting shaft 6 is driven to rotate on the inner wall of the bearing 9 through the moving engagement between the half gear 23 and the tooth plate 24, thereby driving the screening mesh plate 7 to swing back and forth around the connecting shaft 6 through the connecting shaft 6.

[0033] The screening motion mechanism includes a driving component and a stabilizing component. The driving component includes a positioning plate 14. A crankshaft 15 is installed on the inner wall of the positioning plate 14, and one end of the crankshaft 15 is connected to the output end of a driving motor 17. The driving motor 17 is fixed to the device housing 1. A bend neck 1501 is provided on the crankshaft 15, and a first end of a rotating rod 16 is movably mounted on the bend neck 1501.

When the crankshaft 15 rotates to change the height of the rotating rod 16, the rotating rod 16 will drive the connecting rod 18 to move up and down.

[0035] A connecting rod 18 is correspondingly distributed on the inner wall of each rotating rod 16. One end of the connecting rod 18 extends from the top surface of the device housing 1 to the inside of the device housing 1. The connecting rod 18 is fixedly connected to the top surface of the positioning housing 10, and the connecting rod 18 and the rotating rod 16 are movably and rotatably connected.

[0036] The stabilizing assembly includes a skateboard 20, a positioning hole 21 is opened on the top surface of the skateboard 20, a positioning rod 22 is installed on the inner wall of the positioning hole 21, a half gear 23 is installed on the outer surface of the connecting shaft 6, and a tooth plate 24 is installed on the inner wall of the mounting groove 4 and the internal setting plate 3. The skateboard 20 is installed on the outer surface of the positioning shell 10, and the skateboard 20 is slidably connected to the positioning rod 22 through the positioning hole 21, so when the positioning shell 10 moves up and down, the skateboard 20 will provide stable movement for the positioning shell 10 through the connection between the positioning rod 22.

[0037] There are eight slides 20, and each of the eight slides 20 is arranged in a group of four and distributed in a circular array on the outer surfaces of the two positioning shells 10. A positioning hole 21 is correspondingly distributed on the top surface of each slide 20. There are four positioning rods 22, and each of the four positioning rods 22 is arranged in a group of two and distributed on one side surface of the inner wall of the internal setting plate 3 and the mounting groove 4.

[0038] The inner wall of every two positioning holes 21 is slidably connected to the outer surface of a positioning rod 22. The tooth plates 24 are two surfaces distributed on one side of the inner wall of the mounting groove 4 and the internal setting plate 3 respectively. The half gears 23 are two surfaces distributed on the outer sides of the two connecting shafts 6 respectively. The half gears 23 are fixedly connected to the connecting shaft 6. The half gears 23 and the tooth plates 24 are meshed with each other. When the connecting shaft 6 moves up and down, the half gears 23 will move up and down on one side of the tooth plates 24. The connecting shaft 6 is driven to rotate on the inner wall of the bearing 9 through the moving meshing between the half gears 23 and the tooth plates 24, thereby driving the screening mesh plate 7 to swing back and forth around the connecting shaft 6 through the connecting shaft 6.

[0039] Specific usage process: when it is necessary to use the sand and gravel screening and processing equipment for building concrete, the sand and gravel to be screened are put into the equipment casing 1 from the feeding port 2 opened on the top surface of the equipment casing 1. When the sand and gravel are put in, the driving motor 17 is started. When the driving motor 17 is started, the crankshaft 15 connected to its output end is driven to rotate. At this time, the rotating crankshaft 15 will rotate stably on the inner wall of the positioning plate 14, and a rotating rod 16 is installed on the outer surface of the crankshaft 15, so when the crankshaft 15 rotates, the rotating rod 16 on its outer surface is driven to rotate together. The rotating rod 16 is movably rotatably connected to the bend neck 1501. When the crankshaft 15 drives the rotating rod 16 to rotate through the bend neck 1501, the height of the rotating rod 16 will change with the rotation, and the bottom end of the rotating rod 16 is movably rotatably connected to the connecting rod 18. When the crankshaft 15 rotates, When the height of the rotating rod 16 changes, the rotating rod 16 will drive the connecting rod 18 to move up and down. The bottom surface of the connecting rod 18 is fixedly connected to the top surface of the positioning shell 10, so the positioning shell 10 and the slide plate 20 will move up and down with the connecting rod 18 at this time, and the slide plate 20 is slidably connected to the positioning rod 22 through the positioning hole 21, so when the positioning shell 10 moves up and down, the slide plate 20 will provide stable movement for the positioning shell 10 through the connection with the positioning rod 22, so that when the crankshaft 15 rotates, the positioning shell 10 will continuously move up and down to achieve the vibration effect, and the inner wall of the positioning shell 10 is installed with a bearing 9, and the inner wall of the bearing 9 is movably connected to the outer surface of the connecting shaft 6, and the connecting shaft 6 and the screening mesh plate 7 are connected to each other, so at this time, the screening mesh plate 7 will follow the positioning shell 10 to move up and down through the connecting shaft 6 to achieve the vibration function.

[0040] When the connecting shaft 6 and the mesh plate are driven by the crankshaft 15 to move up and down, the half gear 23 installed on the outer surface of the connecting shaft 6 is meshed with the tooth plate 24. Therefore, when the connecting shaft 6 moves up and down, the half gear 23 will move up and down on one side surface of the tooth plate 24, and the connecting shaft 6 is driven to rotate on the inner wall of the bearing 9 through the moving meshing between the half gear 23 and the tooth plate 24, so that the connecting shaft 6 drives the screening mesh plate 7 to swing back and forth with the connecting shaft 6 as the center. Because the screening mesh plate 7 has a certain inclination angle, and the screening mesh plate 7 has the function of small amplitude vibration and reciprocating swing under the drive of the crankshaft 15, when the stone falls on the top surface of the screening mesh plate 7 , larger stones will roll down along the screening mesh plate 7, while smaller stones will fall out of the screening holes 8 opened on the top surface of the screening mesh plate 7, and slide out along the screening outlet 12 opened on the bottom surface of the equipment housing 1, so as to realize the screening of stone size. When the stones roll along the screening mesh plate 7, the reciprocatingly rotating and swinging screening mesh plate 7 will turn over the stones on its surface by rotation, and cooperate with the vibration function of the screening mesh plate 7 to improve the screening efficiency of the stones. If a large amount of stones needs to be screened, the inclination angle of the equipment can be adjusted to change the inclination angle of the screening mesh plate 7, so that the time that the stones stay on the surface of the screening mesh plate 7 is increased, thereby screening the stones more completely.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
