[0035] Embodiment 1

[0036] Reference Figure 1-4 A construction waste treatment device includes a box body 1, a plurality of mounting seats 2 are installed at the bottom of the box body 1, and moving wheels 3 are installed at the bottom ends of the mounting seats 2. There are four moving wheels 3 in total and they are symmetrically distributed. The treatment device of the present invention can be conveniently moved through the four moving wheels 3, avoiding the time cost and labor, equipment and other costs caused by transporting garbage.

[0037] A hopper 4 is installed on the top wall of the box body 1, and the bottom of the hopper 4 is connected to the interior of the box body 1. Construction waste such as bricks, concrete blocks, etc. are loaded from the hopper 4 into the box body 1 through engineering equipment such as excavators.

[0038] A side outlet 5 is provided on one side of the bottom of the box body 1, and a conveying mechanism is laterally provided inside the box body 1, and the conveying mechanism includes a first motor 7, a conveying roller 8 and a conveyor belt 9. A bracket 6 is fixed to the outer wall of the box body 1, and the conveying roller 8 is rotatably installed with the bracket 6. The first motor 7 is fixedly installed with the bracket 6, and the driving end of the first motor 7 is installed with the axis of the conveying roller 8, and the conveyor belt 9 is installed on the outside of the two conveying rollers 8.

[0039] The first motor 7 drives the conveying roller 8 to rotate, and drives the conveying belt 9 to convey the crushed garbage. The garbage is crushed in the box 1, and is discharged from the side outlet 5 by the conveying mechanism after crushing.

[0040] Two crushers are symmetrically arranged inside the box 1 and on the upper side of the conveying mechanism. Each crusher is driven by a screw drive mechanism. Each crusher includes a rolling plate 11. A plurality of crushing cones 15 are installed on the side where the two rolling plates 11 are close to each other, and the crushing cones 15 on the two rolling plates 11 are staggered with each other. The crushing cones 15 are all cone-shaped or pyramid-shaped structures, and the crushing cones 15 on one rolling plate 11 are staggered with the crushing cones 15 on the other rolling plate 11.

[0041] The bottom end of the rolling plate 11 is rotatably mounted on the inner wall of the box body 1 through a fixed rotating shaft 12, and the top of the rolling plate 11 is slidably mounted on the inner wall of the box body 1 through a sliding rotating shaft 13;

[0042] Each screw drive mechanism includes a second motor 10, a threaded rod 17, a movable hinge block 18, a connecting rod 19, a fixed hinge block 20 and a slider 21. The second motor 10 is mounted on the top wall of the box body 1. The driving end of the second motor 10 extends downward into the interior of the box body 1 and is mounted on the threaded rod 17. The threaded rod 17 is rotatably mounted on the inner wall of the box body 1 through a bearing seat. The movable hinge block 18 is threadedly mounted on the threaded rod 17. A slider 21 is mounted on the side of the movable hinge block 18 close to the inner wall of the box body 1. A slide groove 22 matching the slider 21 is provided on the inner wall of the box body 1. A connecting rod 19 is hingedly mounted on the side of the movable hinge block 18 close to the rolling plate 11. A fixed hinge block 20 is hingedly mounted on the end of the connecting rod 19 away from the movable hinge block 18. The fixed hinge block 20 is fixed on the side of the rolling plate 11 close to the movable hinge block 18.

[0043] The second motor 10 drives the threaded rod 17 to rotate. The threaded rod 17 cooperates with the thread of the movable hinge block 18 to control the movable hinge block 18 to move up and down. When the movable hinge block 18 moves up and down, the rolling plate 11 can be controlled to rotate and swing around the fixed rotating shaft 12 as the center through the connecting rod 19 and the fixed hinge seat 20. When the two rolling plates 11 are close to each other, the crushing cone 15 installed thereon can be used to crush and crush the garbage falling from the feeding hopper 4. When the two rolling plates 11 are away from each other, the crushed garbage can fall from the gap between the two rolling plates 11 and the crushing cone 15 to the conveying mechanism below, and finally output the box body 1 through the conveying mechanism.

[0044] The inner wall of the box body 1 is provided with an arc-shaped chute 14, and both ends of the sliding shaft 13 are slidably arranged in the arc-shaped chute 14. When the rolling plate 11 rotates and swings with the fixed shaft 12 as the center, the sliding shaft 13 on the upper part of the rolling plate 11 slides in the arc-shaped chute 14, which increases the stability of the swing of the rolling plate 11 and facilitates the crushing of garbage.

[0045] The slider 21 is T-shaped and is slidably disposed in a slide groove 22 provided on the side wall of the box body 1. The slider 21 slides up and down in the slide groove 22 as the movable hinge block 18 moves up and down. The T-shaped structure of the slider 21 can prevent the slider 21 from leaving the slide groove 22, thereby increasing the stability of the movable hinge block 18 and the entire screw drive mechanism.

[0046] A hydraulic rod is installed at the bottom of the mounting base 2, and the bottom end of the hydraulic rod is installed with the moving wheel 3, and the moving wheel 3 is driven by the wheel hub motor. The moving wheel 3 and the entire device are driven by the wheel hub motor, which makes movement more convenient. A hydraulic rod is installed at the bottom of the mounting base 2, and the hydraulic rod can adjust the posture height of the device to maintain the stability of the device when in use.

[0047] A support roller 26 is installed on the inner wall of the bottom of the box body 1, and the support roller 26 is set at the middle position inside the conveyor belt 9. The support roller 26 supports the conveyor belt 9 to prevent the conveyor belt 9 from being damaged by excessive force due to excessive garbage weight. The support roller 26 is rotatably installed inside the box body 1, which can reduce the wear of the conveyor belt 9 when it contacts the support roller 26.

[0048] Embodiment 2

[0049] When the crusher crushes bricks and concrete blocks, the crushed garbage and steel bars may get stuck between the crushing cones 15. Therefore, the second embodiment, based on the first embodiment, also proposes the following technical solutions:

[0050] Reference Figure 5-9Two separation plates 16 are vertically symmetrically installed inside the box body 1 at a position between the two crushers, and the separation plates 16 are fixed to the inner wall of the box body 1. Through holes 25 corresponding to the crushing cones 15 are opened on the two separation plates 16. A bottom outlet 23 is opened at the bottom of the box body 1, and leakage holes 24 are evenly arranged on the conveyor belt 9.

[0051] The size of the through hole 25 provided on the separation plate 16 needs to ensure that the crushing cone 15 will not be affected when the rolling plate 11 swings.

[0052] Since the separation plate 16 is fixedly installed with the box body 1, when the two rolling plates 11 swing back to the initial position after crushing the garbage, the garbage and steel bars stuck between the crushing cones 15 can be separated by the blocking of the separation plate 16, so that the garbage and steel bars can smoothly fall onto the conveyor belt 9 of the conveying mechanism. Since the conveyor belt 9 is evenly provided with leakage holes 24, the crushed garbage can pass through the leakage holes 24 and fall to the bottom outlet 23 of the box body 1, so that the bottom outlet 23 leaves the box body 1, and the steel bars are transported through the conveyor belt 9 and finally leave the box body 1 from the side outlet 5.

[0053] The aperture of the leakage hole 24 is determined according to the size of the pulverized garbage, and the size of the pulverized garbage is determined by the setting density of the crushing cone 15 .

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
