The front end of the box body 1 is fixedly connected to an electric telescopic rod 406, and the top of the electric telescopic rod 406 is fixedly connected to a moving frame 405. The moving frame 405 is driven by the electric telescopic rod 406 to move vertically. A set of fixed plates 402 are fixedly connected to the left and right ends of the box body 1. The fixed plates 402 play a guiding role. A set of rotating plates 403 are rotatably connected to the front and rear ends of the box body 1. The rotation point of the rotating plate 403 is located at the bottom, and the rotation direction is outward rotation, and is divided into rotation toward the inner wall of the box body 1. The outer wall of the box body 1 is fixedly connected with a connecting frame 404, and the connecting frame 404 is set in an L shape. The top of the connecting frame 404 is rotatably connected with a telescopic plate 408. The rotation of the telescopic plate 408 is rotated with the top of the connecting frame 404, and the rotation direction is toward the inner wall of the box body 1. The outer wall of the telescopic plate 408 is fixedly connected with a moving column 409, and the outer wall of the supporting leg 3 is provided with a shaking mechanism 5, which can collect and process the crushed garbage to avoid accumulation.

[0035] Reference Figure 1-Figure 3The outer wall of the rotating plate 403 is fixedly connected with a counterweight block 410. The counterweight block 410 is arranged so that the rotating plate 403 can only rotate toward the outer wall of the box body 1. The left end of the water tank 401 is fixedly connected to the right end of the box body 1. The water tank 401 is used to store degradation water. The right end of the water spray pipe 407 is connected to the left end of the water tank 401. The degradation water is discharged from the inner wall of the water tank 401 through the water spray pipe 407. The top end of the moving frame 405 contacts the outer wall of the rotating plate 403. The rotating plate 403 is moved upward by the moving frame 405. 403 flips over from an inclined state, and the rotating plate 403 is inclined at forty-five degrees, and the top end of the rotating plate 403 contacts the bottom end of the telescopic plate 408. The rotating plate 403 changes from an inclined state to a vertical state, thereby making the telescopic plate 408 horizontal, and the maximum rotation angle of the rotating plate 403 is forty-five degrees, that is, from an inclined state of forty-five degrees to a vertical state. An outer wall of the fixed plate 402 is provided with an oblique groove, and the outer wall of the movable column 409 contacts the inner wall of the oblique groove, and the oblique groove setting plays a guiding role for the movable column 409.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The shaking mechanism 5 includes a positioning rod 510. The output end of the motor 2 is connected to the rotating column 502 through a belt 501. The belt 501 is driven by the motor 2 to move so that the rotating column 502 rotates. The outer wall of the rotating column 502 is fixedly connected to an ellipsoidal ball 508. The rotation of the rotating column 502 drives the ellipsoidal ball 508 to rotate. The bottom end of the box body 1 is fixedly connected to a support rod 509. The outer wall of the support rod 509 is fixedly connected to a positioning plate 507. The support rod 509 is set to be L-shaped. The positioning plate 5 The outer wall of 07 is elastically connected to the movable plate 505 through a reset spring 506. The movable plate 505 will move laterally. The outer wall of the movable plate 505 is detachably installed with a clamping ring 504. The clamping ring 504 is composed of two groups of semi-rings rotatably connected, and a buckle is provided on the semi-ring for limiting the semi-ring. The clamping ring 504 is installed on the movable plate 505, so that the movement trajectories of the two are the same. The outer wall of the clamping ring 504 is fixedly connected to a collecting box 503, and the crushed construction waste is collected by the collecting box 503.

[0037] Reference Figure 4 and Figure 5The outer wall of the positioning rod 510 is fixedly connected to the outer arc surface of the supporting leg 3, and the outer wall of the rotating column 502 is rotatably connected to the outer wall of the positioning rod 510. The supporting leg 3 can support the positioning rod 510. One end of the return spring 506 is fixedly connected to the outer wall of the movable plate 505, and the other end of the return spring 506 is fixedly connected to the outer wall of the positioning plate 507. The outer wall of the movable plate 505 is slidably connected to the outer arc surface of the supporting rod 509. The elasticity of the return spring 506 makes the movable plate 505 have a return and shake function. An elliptical hole is provided on the outer wall of the collection box 503, and the outer wall of the elliptical ball 508 contacts the inner wall of the elliptical hole. When the elliptical ball 508 contacts the elliptical hole, the return spring 506 is reset. When the elliptical ball 508 contacts the outer wall of the collection box 503, the return spring 506 is squeezed.

[0038] Working principle: When it is necessary to crush the construction waste, first start the electric telescopic rod 406 so that the electric telescopic rod 406 drives the moving frame 405 to move downward, and the inner wall of the moving frame 405 will not contact the two sets of rotating plates 403. Due to the setting of the counterweight block 410, the two sets of rotating plates 403 are tilted outward by a certain degree of forty-five degrees. When the rotating plate 403 is tilted, the bottom end of the telescopic plate 408 loses support and rotates inward, thereby causing the moving column 409 to move along the inner wall of the fixed plate 402, so that the overall length of the telescopic plate 408 becomes shorter, thereby opening the top of the box body 1. At this time, the construction waste can be discharged into the inner wall of the box body 1 for crushing. When the construction waste is discharged, start the electric telescopic rod 406 to drive the moving frame 405 to move upward, and then the telescopic plate 408 is reset and opened, thereby closing the top of the box body 1, and then start the water pipe 407 for dust reduction.

[0039] When the crushing is completed, the collection box 503 is moved to the bottom end of the box body 1 so that the clamp ring 504 is sleeved on the outer wall of the movable plate 505, and then the clamp ring 504 is closed, and the bottom end of the box body 1 is opened to allow the crushed construction waste to be discharged into the bottom end of the collection box 503. At this time, the motor 2 is started to drive the belt 501 to move, and the belt 501 drives the rotating column 502 to rotate, and then the elliptical ball 508 rotates, so that the collection box 503 moves as a whole, and the collection box 503 is reset by the reset spring 506, so that the collection box 503 shakes, thereby avoiding the accumulation of the collected construction waste.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
