Embodiment 1

[0021] see Figure 1-Figure 4 , the present invention provides a technical solution: a crushing multi-stage screening device for building sand and gravel aggregates, including a screening box 13, the top of the screening box 13 is welded with a first filter plate 7, and the middle part of the upper surface of the screening box 13 A feed hopper 10 is provided, and a driving motor 12 is arranged on the top of the screening box 13. The output end of the driving motor 12 is provided with a pulverizing knife 9, and the first crushing teeth 8 are welded on both sides of the pulverizing knife 9. The bottom of the screening box 13 A screening mechanism 3 is provided at the end, and the screening mechanism 3 includes a second support plate 39. A second filter plate 33 is arranged above the second support plate 39. One end of the upper surface of the second support plate 39 is welded with the second filter plate 33. Corresponding to the first hydraulic cylinder 32, the third filter plat...

Embodiment 2

[0025] On the basis of Embodiment 1, in order to make the crushing effect of the screening device better, in the present embodiment, preferably, the top of the screening box 13 is provided with a crushing plate 11 corresponding to the crushing knife 9, and the crushing plate 11 and the screening box 13 is provided with a buffer spring 15, and the lower surface of the crushing plate 11 is provided with a second crushing tooth 17;

[0026] When in use, the splashed sand and gravel are further broken by the crushing plate 11 and the second crushing tooth 17. With the use of the crushing knife 9, the crushing effect of the screening device on the sand and gravel is better, and the buffer spring 15 plays a buffering role to prevent sand and gravel. The impact of stones produces loud noises;

[0027] In order to make the use of the second crushing teeth 17 more reliable, in this embodiment, preferably, the second crushing teeth 17 and the crushing plate 11 are integrally formed, and...
