Description

Technical Field

[0001] This utility model relates to the field of construction waste technology, and more specifically to a crushing device for construction waste. Background Technology

[0002] Construction waste refers to the waste generated during construction and demolition, mainly including recyclable and non-recyclable building materials such as bricks, tiles, concrete, steel, and wood.

[0003] In existing technologies, waste is inevitably generated in the construction environment. The waste needs to be processed by crushing. However, if there are metal parts in the waste during crushing, the metal parts may be mixed together when discharged. Mixed waste increases the complexity of subsequent processing, making the classification, treatment and disposal of waste more difficult. Additional equipment and manpower may be needed to separate the metal from the waste. Utility Model Content

[0004] In view of this, the present invention provides a crushing device for construction waste, which aims to solve the above-mentioned technical problems.

A negative pressure machine is provided on the outer side of one end of the dust cylinder, and the outer side of one end of the dust cylinder is fixedly connected to the inner wall of one end of the negative pressure machine.

[0010] In a preferred embodiment, one side of the negative pressure machine is fixedly connected to one side of the crushing chamber, and a buffer chamber is provided on one side of the crushing chamber, with one side of the crushing chamber fixedly connected to one side of the buffer chamber.

[0011] In a preferred embodiment, a worm gear is provided at one side end of the guide plate, and the side end of the guide plate is rotatably connected to the top end of the worm gear.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] like Figures 1-4As shown, this utility model provides a technical solution: a crushing device for construction waste, comprising: a crushing mechanism 1, a collecting mechanism 2 at one end of the crushing mechanism 1, the crushing mechanism 1 including a crushing chamber 11, a guide plate 13 provided on the inner surface of the crushing chamber 11, the inner surface of the crushing chamber 11 being fixedly connected to one end of the guide plate 13, an electromagnetic plate 14 provided on the inner wall of the guide plate 13, the inner wall of the guide plate 13 being rotatably connected to the middle end of the electromagnetic plate 14, and an output plate 18 provided on the inner surface of the crushing chamber 11, the inner surface of the crushing chamber 11 being connected to the middle end of the output plate 18. The output plate 18 is fixedly connected to the inner wall of the output plate 18, which is slidably connected to the outer side of the inner rod 19. A telescopic rod 110 is provided at one bottom end of the inner rod 19, and is fixedly connected to one end of the telescopic rod 110. The outer side of the telescopic rod 110 is fixedly connected to one end of the inner surface of the crushing chamber 11. A dust cylinder 111 is provided at one end of the inner wall of the guide plate 13, and is fixedly connected to the outer side of the dust cylinder 111. A negative pressure unit 112 is provided at one end of the dust cylinder 111. One end of the dust collector 111 is fixedly connected to the inner wall of one end of the negative pressure unit 112. One side of the negative pressure unit 112 is fixedly connected to one side of the crushing chamber 11. A buffer chamber 113 is provided on one side of the crushing chamber 11, and one side of the crushing chamber 11 is fixedly connected to one side of the buffer chamber 113. A worm gear 16 is provided on one side of the guide plate 13, and one side of the guide plate 13 is rotatably connected to the top end of the worm gear 16. A motor 17 is provided at the bottom end of the worm gear 16, and the bottom end of the worm gear 16 is fixedly connected to the output end of the motor 17. The bottom end of the motor 17 is connected to the guide plate. One side end of the worm gear 13 is fixedly connected. A worm wheel 15 is provided on the outer side of the worm gear 16. The outer side of the worm gear 16 is connected to the outer side of the worm wheel 15. The center of the worm wheel 15 is fixedly connected to one side end of the electromagnetic plate 14. A crushing roller 12 is provided on the inner surface of the crushing chamber 11. One end of the crushing roller 12 is rotatably connected to the inner surface of the crushing chamber 11. A second motor 114 is provided on the other end of the crushing roller 12. The other end of the crushing roller 12 is fixedly connected to the output end of the second motor 114. One end of the second motor 114 is fixedly connected to one side of the crushing chamber 11.

[0028] In this embodiment, when the construction waste crushing device is in use, the waste is poured into the port of the crushing chamber 11, and then the motor 114 is started to make the crushing roller 12 rotate. The crushing roller 12 is installed below the port, so as it is continuously crushed, the waste will fall naturally onto the guide plate 13 designed below the crushing roller 12. If there are metal objects in the waste, they will be directly attracted by the electromagnetic plate 14 in the guide plate 13, and the waste will slide down along the natural path. The bottom end of the guide plate 13 is located at the discharge port of the crushing chamber 11, so the waste will be discharged from the discharge port. The waste contains dust. By generating negative pressure in the dust cylinder 111 when the negative pressure machine 112 is started, the dust in the waste is absorbed during discharge and then enters the buffer chamber 113. Since the buffer chamber 113 has a certain degree, the dust can be prevented from being discharged directly, allowing it to have a buffering process to prevent a large amount from drifting into the air. In this way, the effective separation of waste and metal can be ensured, and the recycling rate of waste can be improved.

[0029] Secondly, by starting the motor 17, the worm gear 16 drives the worm wheel 15 to rotate. Then, the electromagnetic plate 14 begins to change angle, so that one end of it rests on the output plate 18. Then, the attraction capacity of the electromagnetic plate 14 is turned off, and the metal parts will slide onto the output plate 18 and be discharged outward. In addition, the telescopic rod 110 is extended and retracted back and forth, so that the inner rod 19 reciprocates within the output plate 18. This can prevent jamming during discharge, ensure the smooth discharge of metal parts in the waste, reduce the potential risk of blockage, and improve the working efficiency of the equipment.

[0030] Example 2:

[0031] like Figures 1-4 As shown, the collecting mechanism 2 includes a receiving box 21, a triangular plate 22 is provided on the inner surface of the receiving box 21, the inner surface of the receiving box 21 is fixedly connected to the outer side of the triangular plate 22, and one side of the receiving box 21 is fixedly connected to one end of the crushing chamber 11.

[0032] In this embodiment, a receiving box 21 is installed in the direction of the output plate 18. The receiving box 21 can effectively collect metal parts, reducing the scattering and loss of metal parts, and facilitating subsequent processing or recycling. Furthermore, a triangular plate 22 is designed inside the receiving box 21. The design of the triangular plate 22 plays a guiding role, allowing the collected metal parts to flow smoothly in the box and preventing accumulation in the receiving box 21. This helps maintain the working efficiency of the receiving box 21, ensuring that subsequent operations are not affected by accumulation, and improving overall work efficiency.
