[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] 1.

[0018] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.
[0019] As Figures 1-4 shown, the utility model provides a technical solution: a high-efficiency multi-stage sand and gravel screening device for building construction, including a fixed frame 1, an auxiliary plate 2 is connected to the fixed frame 1, a feeding plate 3 is connected to the auxiliary plate 2, a groove 4 is opened on the feeding plate 3, a sleeve plate 5 is connected to the fixed frame 1, a motor 7 is connected to one side of the fixed frame 1, a collection box 6 is clamped inside the fixed frame 1, a filter cylinder 8 is connected inside the auxiliary plate 2, a driving rod 10 is rotatably connected inside the filter cylinder 8, stirring blades 11 are connected to the outside of the driving rod 10, a connecting plate 13 is slidably connected inside the feeding plate 3, and a filter plate 12 is connected to the connecting plate 13;
[0020] Filter holes 14 are opened inside the filter plate 12, a positioning rod 15 is rotatably connected inside the sleeve plate 5. By setting the collection box 6, when the sand and gravel in the filter cylinder 8 are being screened, the screened sand and gravel will fall into the collection box 6 through the bottom of the filter cylinder 8, enabling the collection box 6 to centrally collect the screened sand and gravel and reducing the subsequent operation process;
[0021] A sleeve 20 is connected to the fixed frame 1, a second bevel gear 25 is connected below the positioning rod 15, a guide rod 21 is rotatably connected inside the sleeve 20, a first bevel gear 22 is connected to one end of the guide rod 21, and the first bevel gear 22 meshes with the second bevel gear 25. By setting the sleeve 20, when the guide rod 21 is affected by a turning force, the guide rod 21 will rotate inside the sleeve 20, enabling the sleeve 20 to play a certain supporting role in the rotation of the guide rod 21 and preventing the guide rod 21 from jamming during rotation;
[0022] A second anti-slip disc 23 is connected to the outside of the guide rod 21, a first anti-slip disc 19 is connected to the outside of the driving rod 10, the first anti-slip disc 19 is externally connected to a transmission belt 24, and the first anti-slip disc 19 is connected to the second anti-slip disc 23 through the transmission belt 24. By setting the first bevel gear 22 and the second bevel gear 25, since the first bevel gear 22 meshes with the second bevel gear 25, the positioning rod 15 and the guide rod 21 can rotate synchronously, enabling the stirring blades 11 and the filter plate 12 to perform synchronous screening on the sand and gravel, ensuring the flexibility of the screening device;
[0023] A moving plate 17 is slidably connected inside a template 5, a swash plate 16 is connected outside a positioning rod 15, two fixing columns 18 are connected to one side of the moving plate 17, the fixing columns 18 are lapped with the swash plate 16, the moving plate 17 is connected to a connecting plate 13, a motor 7 is connected to a driving rod 10, and a first feeding port 9 is formed inside a filter cylinder 8. By arranging the swash plate 16, when the swash plate 16 rotates around the positioning rod 15, the swash plate 16 will drive the moving plate 17 to move inside the template 5, so that the moving plate 17 can realize the function of reciprocating movement, and prevent the sand and gravel in the filter plate 12 from being blocked due to long-term accumulation.
[0024] The working principle of the present utility model is as follows:
[0025] When the screening device is screening sand and gravel, the sand and gravel are fed through the groove 4, the motor 7 drives the stirring blade 11 to rotate around the driving rod 10. Since the anti-slip disk one 19 on the surface of the driving rod 10 is connected to the anti-slip disk two 23 through the transmission belt 24, the guide rod 21 rotates synchronously with the driving rod 10. Since the bevel gear one 22 meshes with the bevel gear two 25, the positioning rod 15 will rotate along with the driving rod 10. Since the two fixing columns 18 are lapped with the swash plate 16, when the swash plate 16 rotates, the fixing columns 18 will drive the moving plate 17 to reciprocate inside the template 5. The filter plate 12 will move inside the feeding plate 3 along with the connecting plate 13. The filter holes 14 in the filter plate 12 will perform primary screening on the sand and gravel, and the filtered sand and gravel will fall into the filter cylinder 8 through the first feeding port 9. When the stirring blade 11 rotates, it will beat the sand and gravel, and then perform secondary screening on the sand and gravel. The screened sand and gravel will fall into the collection box 6.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
[0027] The above has made a detailed description of the preferred embodiment of the present patent, but the present patent is not limited to the above embodiment. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present patent.
