Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a device for recycling building construction waste. Background Technology

[0002] Building construction is the process of transforming design drawings into a physical building, involving multiple stages such as foundation engineering, main structure, roofing, and decoration. This process requires the cross-operation of multiple trades and procedures, as well as a large amount of materials, machinery, and human resources. During construction, it is essential to strictly adhere to design requirements, construction specifications, and safety regulations to ensure construction quality and safety.

[0003] A large amount of waste is generated during the construction process. Among them, broken bricks, concrete, mortar, and pile heads account for about 80% of the total construction waste. If these wastes are discarded directly without treatment, they will not only pollute the environment, but landfill will also consume a lot of manpower and resources. Therefore, a construction waste recycling device is needed.

[0004] Current construction waste recycling devices typically crush stones and concrete into uniformly sized small stones for use in road construction, pile foundation filling, and foundation work, thus achieving recycling and reuse. However, in actual use, when crushing some relatively smooth round stones, the smooth surface makes them difficult to squeeze by the crushing device, causing them to bounce continuously under the pressure of the crushing device. This not only affects the crushing efficiency of the device but also may cause them to pop out of the discharge port, posing a certain safety hazard. Therefore, a construction waste recycling device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a construction waste recycling device, which aims to improve the problem that smooth, round stones are not easy to break in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a construction waste recycling device, comprising a base, a feeding port fixedly connected to the top surface of the base, a slide rail fixedly connected to the inner side of the feeding port, a power component provided on the right side of the slide rail, a threaded rod provided at the bottom end of the power component, a sliding block threadedly connected to the outer circumference of the threaded rod, an anti-jump box fixedly connected to the left side of the sliding block, a limit sleeve fixedly connected inside the anti-jump box, a sliding circular groove provided inside the limit sleeve, a vibration damping circular groove provided at the top end of the sliding circular groove, an annular groove provided on the inner wall of the side of the vibration damping circular groove, a sliding block elastically connected to the inner wall of the top end of the sliding circular groove by a limit spring, a connecting column fixedly connected inside the sliding block, a connecting block fixedly connected to the top end of the connecting column, a rubber ring fixedly connected to the outer circumference of the connecting block, and an anti-jump plate fixedly connected to the bottom end of the connecting column.

[0007] As a further description of the above technical solution:

[0008] A dust collection box is fixedly connected inside the base. An inclined filter screen is provided inside the dust collection box, and a dust collection fan is provided outside the dust collection box.

[0009] As a further description of the above technical solution:

[0010] A power box is located on the right side of the machine base, and a twin-shaft crusher is installed inside the machine base. The power box and the twin-shaft crusher are electrically connected.

[0011] As a further description of the above technical solution:

[0012] The power assembly includes a motor bracket, the front of which is fixedly connected to the back of the slide rail, a rotating motor is fixedly connected to the front of the motor bracket, and the top of the threaded rod is fixedly connected to the bottom output shaft of the rotating motor.

[0013] As a further description of the above technical solution:

[0014] The outer circumference of the threaded rod is rotatably connected to the inside of the slide rail, and the outer circumference of the sliding block is slidably connected to the inside of the slide rail.

[0015] As a further description of the above technical solution:

[0016] One end of the limiting spring is fixedly connected to the inner wall of the top of the sliding groove, and the other end of the limiting spring is fixedly connected to the top of the sliding block. The outer periphery of the sliding block is slidably connected to the inside of the sliding groove.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the connecting block side does not contact the inner wall of the vibration damping groove side, and the outer circumference of the rubber ring is engaged inside the groove.

[0019] As a further description of the above technical solution:

[0020] The bottom surface of the anti-jump board is provided with several sets of protrusions whose side outer walls are inclined.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting a slide rail, a slider, and a threaded rod, when the round stone cannot be crushed, the rotating motor is turned on to lower the anti-jump box, which restricts the jumping of the round stone and increases the contact between the round stone and the dual-shaft crusher. At the same time, the limit spring and rubber ring are used to generate buffer, which reduces the impact force of the round stone and avoids the crushing plate from breaking.

[0023] 2. In this utility model, by setting up a dust collection box, a dust collection fan and an inclined filter screen, the fan is turned on to ensure that the dust escaping from the discharge port is sucked in, which significantly reduces the suspended particulate matter in the air and reduces environmental pollution. At the same time, the inclined filter screen prevents stones from sliding off the sides and ensures the crushing effect. Attached Figure Description

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a construction waste recycling device, comprising a base 1 for supporting and fixing the equipment. A power box 2 is located on the right side of the base 1. A twin-shaft crusher 3 for crushing stones is installed inside the base 1. The power box 2 and the twin-shaft crusher 3 are electrically connected, and the power box 2 provides power to the twin-shaft crusher 3. A feeding port 4 is fixedly connected to the top surface of the base 1. A slide rail 5 is fixedly connected to the inner side of the feeding port 4. A power assembly is located on the right side of the slide rail 5. The power assembly provides the power required for lifting and lowering. The power assembly includes a motor bracket 6 that provides fixed support. The motor bracket 6 is fixedly connected to the back of the slide rail 5. The front of the motor bracket 6 is fixedly connected to the rotating motor 7, which provides rotational power. The bottom of the power component is provided with a threaded rod 8. The top of the threaded rod 8 is fixedly connected to the bottom output shaft of the rotating motor 7. When the rotating motor 7 is turned on, the bottom output shaft of the rotating motor 7 drives the threaded rod 8 to rotate. The outer circumference of the threaded rod 8 is threadedly connected to a sliding block 9. The rotation of the threaded rod 8 can drive the sliding block 9 to slide up and down. The outer circumference of the sliding block 9 is slidably connected to the inside of the slide rail 5. The slide rail 5 restricts the sliding block 9 from rotating and can only slide up and down along the inner wall of the slide rail 5. The left side of the sliding block 9 is fixedly connected to an anti-jump box 10.

[0032] Reference Figures 2-4The anti-jump box 10 has four sets of limiting sleeves 11 fixedly connected inside, evenly distributed at the four corners of the bottom of the anti-jump box 10. Each limiting sleeve 11 has a sliding groove 12 inside, and a vibration-damping groove 13 is formed at the top of the sliding groove 12. The diameter of the vibration-damping groove 13 is slightly smaller than that of the sliding groove 12. Multiple sets of annular grooves 14 are formed on the inner wall of the side of the vibration-damping groove 13, linearly and evenly distributed. A sliding block 16 is elastically connected to the inner wall of the top of the sliding groove 12 via a limiting spring 15. When the sliding block 16 is not under force, the limiting spring 15 will push the sliding block 16 downwards. One end of the limiting spring 15 is fixedly connected to the inner wall of the top of the sliding groove 12, and the other end is fixedly connected to the top of the sliding block 16. The outer circumference of the sliding block 16 is slidably connected to the sliding groove 12. Inside 2, the sliding groove 12 restricts the sliding block 16 to slide up and down only along the inner wall of the sliding groove 12. The sliding block 16 is fixedly connected to a connecting column 17, which serves as a fixed connection. The top of the connecting column 17 is fixedly connected to a connecting block 18. A rubber ring 19 is fixedly connected to the outer periphery of the connecting block 18. The rubber ring 19 has a certain elasticity and will deform and generate elastic force when subjected to thrust. The outer side wall of the connecting block 18 does not contact the inner side wall of the vibration damping groove 13, leaving a gap between them to accommodate the rubber ring 19 after deformation. The outer periphery of the rubber ring 19 is engaged inside the ring groove 14. The bottom end of the connecting column 17 is fixedly connected to an anti-jump plate 20. The bottom surface of the anti-jump plate 20 is provided with several sets of protrusions with inclined outer side walls. In this way, when a stone hits the anti-jump plate 20, it can disperse the impact force, reduce the longitudinal pressure, and prevent the anti-jump plate 20 from breaking.

[0033] Reference Figure 2 The base 1 is fixedly connected to a dust collection box 21 for holding dust. There are two sets of dust collection boxes 21, which are symmetrically arranged inside the base 1. The inner side of the dust collection box 21 is provided with an inclined filter screen 22. The two sets of inclined filter screens 22 form a cavity that is larger at the top and smaller at the bottom, so that the stones will enter the middle of the twin-shaft crusher 3 and prevent the stones from passing through from the sides. The outer side of the dust collection box 21 is provided with a dust collection fan 23 to provide the suction power required for dust collection.

[0034] Working principle: When a relatively smooth stone is put into the feeding port 4 and cannot be quickly crushed, the rotating motor 7 is turned on. The output shaft at the bottom of the rotating motor 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the sliding block 9 to move downward. The sliding block 9 drives the anti-jump box 10 to move downward. The anti-jump box 10 drives the anti-jump plate 20 to move downward. When the anti-jump plate 20 contacts the top of the stone, the impact of the stone bouncing upward will be partially absorbed by the protrusion at the bottom of the anti-jump plate 20 and push the anti-jump plate 20 upward. The anti-jump plate 20 drives the connecting column 17 to move upward. The connecting column 17 drives the sliding round block 16 and the connecting round block 18 to move upward, while squeezing the limit spring 15 to generate buffer. At the same time, the connecting round block 18 drives the rubber ring 19 to move upward. The rubber ring 19 deforms under force and generates greater resistance, thereby reducing the vibration of the anti-jump plate 20 and reducing the bouncing of the stone, so that the stone is quickly crushed. When stones are fed into the feeding port 4, they fall onto the inclined screen 22 and move along the inclined plane towards the middle position of the twin-shaft crusher 3 to prevent the stones from sliding off the sides. At the same time, the dust extraction fan 23 is turned on, and the dust extraction fan 23 generates suction to suck away the dust generated when the stones are crushed.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
