The notch, the end plate 22 is located in the notch of the flip body 23. In this solution, by setting a detachable sieve plate 21, the flip body 23 is rotated so that the flip body 23 is located on one side of the end plate 22, the end plate 22 is removed, and the sieve plate 21 is pulled out. A plurality of sieve plates 21 with different mesh sizes can be set correspondingly for screening particles of different coarse and fine sizes. By replacing the sieve plates 21 with different mesh sizes, the screening of concrete of multiple specifications can be achieved. The sieve plates 21 are simple and flexible when disassembling and assembling, and the efficiency is high. When installing the sieve plate 21, the sieve plate 21 is inserted into the slot 25, and the end plate 22 is placed on the support plate 24. The flip body 23 is flipped to one side of the end plate 22 under the action of gravity, and the flip body 23 and the support plate 24 are turned over. 4 are respectively close to the two ends of the end plate 22, thereby realizing the limitation of the end plate 22.

The elastic telescopic rod 31 is located below the middle of the sieve plate 21. The depressed sieve plate 21 pushes the support plate to push down the output shaft of the elastic telescopic rod 31, thereby supporting and cushioning the middle position of the sieve plate 21. By providing a vibration motor 32, the support rod 30 and the plug-in part 20 can vibrate, thereby improving the screening efficiency of the sieve plate 21. During civil engineering construction, concrete aggregates can be screened on site.
