Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-6 A construction waste treatment device includes a crushing hopper 1, a support plate 2, a support column 3, a stirring motor 4, a first gear 5, a second gear 6, a first transmission wheel 7, a transmission belt 8, a frame 9, a support rod 10, a second transmission wheel 11, a pressure plate 12, a slide 13, a through groove 14, a connecting plate 15, a spring frame 16, an outer plate 17, a first transmission shaft 18, blades 19, a second transmission shaft 20, a screen 21, and a slider 22. Support plates 2 are fixedly installed on both sides of the crushing hopper 1, and support columns 3 are welded to the bottom of the support plates 2. A stirring motor 4 is installed on the top of the support plates 2, and a first gear 5 is installed at one end of the stirring motor 4. A second gear is connected to one side of the first gear 5. 6. The second gear 6 is connected to the crushing hopper 1 via the transmission shaft 20, and the first transmission wheel 7 is fixedly installed on the front of the second gear 6. A frame 9 is provided below the crushing hopper 1, and multiple sets of support rods 10 are provided at the bottom of the frame 9. The first transmission wheel 7 and the second transmission wheel 11 form a belt drive through the transmission belt 8, and the second transmission wheel 11 is installed on the outside of the frame 9. A pressure plate 12 is fixedly installed on the outside of the second transmission wheel 11. A screen 21 is provided inside the frame 9, and connecting plates 15 are fixedly installed on both sides of the screen 21. The connecting plates 15 penetrate the frame 9 and are fixedly connected to the outer plate 17. Multiple sets of spring frames 16 are provided on both sides of the connecting plates 15. A through groove 14 is opened on the front of the frame 9.

[0023] like Figure 1 and 2 As shown, the outer plate 17 forms a sliding structure with the slide groove 13 via the slider 22.

[0024] like Figure 1 and 3 As shown, the number of teeth of the first gear 5 is less than the number of teeth of the second gear 6, and the rotational speed of the second gear 6 is slower than that of the first gear 5.

[0025] like Figure 1 and 3As shown, a first drive shaft 18 is installed at one end of the first gear 5 and extends into the interior of the crushing hopper 1. Multiple sets of blades 19 are installed on the outer side of the first drive shaft 18. The stirring motor 4 drives the first gear 5 to rotate, so that the first drive shaft 18 at one end of the first gear 5 drives the blades 19 to rotate, thereby breaking up the construction waste entering the crushing hopper 1. The broken construction waste falls on the top of the screen 21.

[0026] like Figure 1 and 5 As shown, the screen 21 is set at an angle, and the scraps falling on the screen 21 will roll to the lower left end.

[0027] Working principle: In operation, the excavator is first used by personnel to dig construction waste into the crushing hopper 1. At the same time, the mixing motor 4 is started, which drives the first gear 5 to rotate. This causes the first drive shaft 18 at one end of the first gear 5 to drive the blades 19 to rotate, thereby breaking up the construction waste entering the crushing hopper 1. The broken construction waste falls to the top of the screen 21, while powder will fall to the bottom of the screen 21. The crushed material cannot pass through the screen 21 and rolls to the left side of the screen 21. Below the end, the powder and crushed materials are screened. At the same time, the first gear 5 drives the second gear 6 to rotate together. When the second gear 6 rotates, the outer first transmission wheel 7 drives the second transmission wheel 11 to rotate together through the transmission belt 8. The pressure plate 12 on the outside of the second transmission wheel 11 will continuously push the outer plate 17, so that the outer plate 17 slides in the slide groove 13 through the slider 22. The connecting plate 15 and the screen 21 will vibrate through the spring frame 16, thereby preventing construction waste from clogging the screen 21.
