Description

Technical Field

[0001] This utility model belongs to the technical field of concrete recycling devices, specifically a concrete recycling device. Background Technology

[0002] Waste concrete refers to discarded concrete blocks, such as concrete blocks and fine sand after a building is dismantled and crushed. These can be recycled as concrete. An existing patent (publication number: CN216936226U) describes a concrete recycling device that solves the problem that some concrete recycling devices cannot screen crushed concrete, making subsequent classification and processing inconvenient. However, this concrete recycling device does not have a dust absorption function, causing dust to scatter everywhere during the crushing process, which seriously affects the working environment. Utility Model Content

[0003] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a concrete recycling device, which effectively solves the problem that the existing concrete recycling devices do not have the function of absorbing dust, causing dust to be scattered everywhere during the concrete crushing process, which seriously affects the working environment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete recycling device, comprising a support plate, four support legs fixedly installed at the bottom of the support plate, the four support legs being distributed along the four corners of the bottom of the support plate, a crushing and recycling device body fixedly installed at the center of the top of the support plate, a feed hopper fixedly installed at the top of the crushing and recycling device body, two crushing rollers installed inside the crushing and recycling device body, an equipment mounting box fixedly installed on one side of the top of the support plate, an L-shaped mounting frame fixedly installed at the top of the equipment mounting box, a vertical transmission assembly inside the equipment mounting box and the L-shaped mounting frame, a dust absorption assembly on the other side of the top of the support plate, and a discharge valve fixedly installed at the bottom of the crushing and recycling device body.

[0005] Preferably, the dust absorption assembly includes a collection tank, which is fixedly installed on the top of the support plate on the side away from the equipment mounting box. A discharge valve is fixedly installed on the surface of the collection tank. A vacuum cleaner is fixedly installed on the top of the collection tank. A conveying pipe is fixedly installed on the top of the vacuum cleaner. A connector is fixedly installed at the end of the conveying pipe away from the vacuum cleaner. A collection hopper is fixedly installed at the bottom of the connector. The collection hopper is located directly above the feed hopper. A first connecting rod is fixedly installed on one side of the collection hopper.

[0006] Preferably, the vertical transmission assembly includes a drive motor, which is fixedly installed on the inner wall of one side of the equipment mounting box. A turntable is fixedly installed at the output end of the drive motor. A movable frame is provided on the upper side of the turntable. A second connecting rod is fixedly installed on one side of the movable frame. A third connecting rod is fixedly installed on both sides of the upper part of the second connecting rod. A positioning sleeve is fixedly installed at the ends of the two third connecting rods that are far apart from each other.

[0007] Preferably, each positioning slide sleeve has a positioning slide rod inserted inside. The tops of the two positioning slide rods are respectively fixedly installed on both sides of the top inside the L-shaped mounting bracket. The upper side of the surface of each positioning slide rod is provided with a return spring. The top and bottom of the two return springs are respectively fixedly connected to the top inside the L-shaped mounting bracket and the top of the positioning slide sleeve. The positioning slide sleeve near the collection hopper is fixedly connected to the end of the first connecting rod away from the connector.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] During operation, the operator feeds concrete blocks into the hopper, where they are crushed by crushing rollers. The crushed concrete is then discharged through the discharge valve. Simultaneously, the operator activates a vacuum cleaner, which collects dust from the hopper via a conveying pipe, connector, and collection hopper. The dust is then discharged through the discharge valve. Simultaneously, the operator starts the drive motor, rotating the turntable. This rotation lowers the moving frame, which, via a second connecting rod and two third connecting rods, causes two positioning sleeves to slide downwards along their surfaces. Two return springs, through their own elasticity, push the positioning sleeves downwards, ensuring a stable and effective downward movement of the moving frame. The downward movement of one of the positioning sleeves, along with the first connecting rod, moves the connector and collection hopper downwards, bringing the collection hopper closer to the hopper and enhancing dust collection. This provides the concrete recycling device with excellent dust absorption capabilities, preventing dust from scattering during the crushing process and ensuring a safe working environment.

[0017] Depend on Figures 1 to 3 The present invention includes a support plate 1, four support legs 2 fixedly installed at the bottom of the support plate 1, the four support legs 2 being distributed along the four corners of the bottom of the support plate 1, a crushing and recycling device body 3 fixedly installed at the center of the top of the support plate 1, a feed hopper 4 fixedly installed at the top of the crushing and recycling device body 3, two crushing rollers 5 installed inside the crushing and recycling device body 3, an equipment mounting box 6 fixedly installed on one side of the top of the support plate 1, an L-shaped mounting frame 7 fixedly installed on the top of the equipment mounting box 6, a vertical transmission assembly inside the equipment mounting box 6 and the L-shaped mounting frame 7, a dust absorption assembly on the other side of the top of the support plate 1, and a discharge valve 23 fixedly installed at the bottom of the crushing and recycling device body 3.

[0018] During operation, the operator feeds concrete blocks into the feed hopper 4, where they are crushed by the crushing roller 5. The crushed concrete is then discharged through the discharge valve 23. Simultaneously, the operator activates the dust absorption assembly to absorb dust emanating from the feed hopper 4. At the same time, the operator activates the vertical transmission assembly to move the dust absorption assembly downwards, bringing it closer to the feed hopper 4 and increasing its dust collection efficiency. This ensures the concrete recycling device has a good and effective dust absorption function, preventing dust from scattering during the crushing process and protecting the working environment.

[0019] The dust absorption assembly includes a collection tank 8, which is fixedly installed on the top of the support plate 1 on the side away from the equipment mounting box 6. A discharge valve 9 is fixedly installed on the surface of the collection tank 8. A vacuum cleaner 10 is fixedly installed on the top of the collection tank 8, and a conveying pipe 11 is fixedly installed on the top of the vacuum cleaner 10. A connector 12 is fixedly installed at the end of the conveying pipe 11 away from the vacuum cleaner 10. A collection hopper 13 is fixedly installed at the bottom of the connector 12. The collection hopper 13 is located directly above the feed hopper 4, and a first connecting rod 14 is fixedly installed on one side of the collection hopper 13. The vertical transmission assembly includes a drive motor 15, which is fixedly installed on the inner wall of one side of the equipment mounting box 6. A turntable 16 is fixedly installed at the output end of the drive motor 15. The upper part of the turntable 16... A movable frame 17 is provided on the side. A second connecting rod 18 is fixedly installed on one side of the movable frame 17. A third connecting rod 19 is fixedly installed on both sides of the upper part of the second connecting rod 18. A positioning sleeve 20 is fixedly installed at the ends of the two third connecting rods 19 that are far apart from each other. A positioning slide rod 21 is inserted into the inside of the positioning sleeve 20. The tops of the two positioning slide rods 21 are fixedly installed on both sides of the top inside the L-shaped mounting frame 7. A return spring 22 is provided on the upper side of the surface of the positioning slide rod 21. The top and bottom of the two return springs 22 are fixedly connected to the top inside the L-shaped mounting frame 7 and the top of the positioning sleeve 20, respectively. The positioning sleeve 20 near the collection hopper 13 is fixedly connected to the end of the first connecting rod 14 that is far away from the connector 12.

[0020] While the concrete blocks are being crushed, the operator starts the vacuum cleaner 10. The vacuum cleaner 10 absorbs the dust that is scattered from the feed hopper 4 into the collection tank 8 through the conveying pipe 11, the connector 12, and the collection hopper 13. The operator opens the discharge valve 9 to discharge the dust. At the same time, the operator starts the drive motor 15 to drive the turntable 16 to rotate. When the turntable 16 rotates, it drives the moving frame 17 to move down. When the moving frame 17 moves down, it drives the two positioning sleeves 20 to slide down along the surface of the two positioning slide rods 21 through the second connecting rod 18 and the two third connecting rods 19. At the same time, the two return springs 22 push the two positioning sleeves 20 down through their own elasticity, so that the moving frame 17 can move down stably and effectively. When one of the positioning sleeves 20 moves down, it drives the connector 12 and the collection hopper 13 to move down through the first connecting rod 14, so that the collection hopper 13 can be closer to the feed hopper 4, which increases the dust collection effect.
