[0031] like Figure 1 , Figure 3 Figure 4 As shown, a baffle 38 is fixedly mounted on the top of the screening plate 3, and the number of the baffles 38 is five. The baffles 38 are provided to help reduce the moving speed of the sand and gravel, thereby improving the screening effect of the sand and gravel.
[0032] like Figure 1 and Figure 2 As shown, limit plates 39 are fixedly assembled on both sides of the screening plate 3. The cross-sectional shape of the limit plates 39 is a right triangle, and the hypotenuse of the limit plates 39 is located on the side close to the baffle 38. By setting the limit plates 39, it is helpful to limit the sand and gravel on the screening plate 3 to prevent the sand and gravel from falling during the screening process.

By limiting the spring 22 and the electromagnetic vibrator 23, it is beneficial to ensure the screening effect of sand and gravel and improve the screening efficiency.
[0036] The technical solution provided by the utility model is that when in use, the slot 31 at the bottom of the screening plate 3 is first aligned with the fixing pin 25 on the fixing plate 24, and when the locking tooth 35 receives the fixing pin 25 and moves to the depth of the circular slot 32, when the fixing pin 25 is completely pressed into the slot 31, the locking tooth 35 loses the extrusion, and at this time, the spring 2 33 pushes the connecting block 34 and the locking tooth 35 to move in the direction of the fixing pin 25 until they are locked and fixed with the fixing pin 25, thereby completing the fixing of the screening plate 3. When it is necessary to disassemble for cleaning or replacement after use, it is only necessary to pull the pull rod 37 to the depth of the circular slot 32 to drive the locking tooth 35 to separate from the fixing pin 25, and then the screening plate 3 can be removed;
