Description

Technical Field

[0001] This utility model relates to the field of building demolition material crushing technology, and more specifically, to an environmentally friendly building demolition crushing device. Background Technology

[0002] With the acceleration of urbanization, the amount of demolition materials generated from building demolition is increasing day by day. In response to environmental protection requirements, it is necessary to crush and recycle these materials.

[0003] A search revealed that patent application CN202322565977.5 discloses a solid material crushing device for building demolition, relating to the field of solid material crushing. It includes a base plate with a shell mounted on top, and a discharge port on the side of the shell. When the user needs to suppress dust generated by the crushed solid material falling from the discharge port, the user can open the pump body, which draws water from a storage tank. The pump body then transmits the stored water through a water pipe to an atomizing nozzle, which sprays the atomized water to suppress the dust generated by the crushed solid material falling from the discharge port. The user can also start a first motor, which drives a first rotating shaft, which in turn drives a conveyor belt. The conveyor belt rotates, transporting the crushed solid material from the discharge port to the first motor, thus conveying the crushed solid material to a designated location for easy discharge. However, the following drawbacks still exist:

[0004] (1) The existing crushing device can only crush the building demolition object once, resulting in incomplete crushing and poor crushing effect. In addition, the dust generated during the crushing process is easy to drift out from the inlet and pollute the environment.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes an environmentally friendly building demolition crushing device, including a crushing box 1. Two first crushing rollers 2 are rotatably connected inside the crushing box 1. Two second crushing rollers 3 are located below the two first crushing rollers 2. The first crushing rollers 2 perform preliminary crushing of the building demolition material, while the second crushing rollers 3 perform fine crushing, improving the crushing effect. The shaft ends of the two second crushing rollers 3 are rotatably connected to the side wall of the crushing box 1. Guide plates 4 are provided on the upper sides of both the first crushing rollers 2 and the second crushing rollers 3, and the guide plates 4 are fixedly connected to the crushing box 1. The crushing box 1 is equipped with a power structure 5 for driving the first crushing rollers 2 and the second crushing rollers 3 to rotate. A feed hopper 6 is fixed to the top of the crushing box 1, and a dust suppression structure 7 is provided on the upper surface of the feed hopper 6 to facilitate the collection of dust particles. The dust is treated for dust suppression, making it more environmentally friendly. A discharge head 8 is fixed to the lower end of the crushing box 1. A rotating head 9 is rotatably connected to the discharge head 8. A conveying pipe 10 is fixedly connected to the bottom end of the rotating head 9. An angle adjustment structure 11 is provided on the conveying pipe 10. A conveying shaft 12 is rotatably connected inside the conveying pipe 10. A spiral blade 13 is fixed on the conveying shaft 12. A first motor 14 is fixed to the bottom end of the conveying pipe 10. The drive end of the first motor 14 is fixedly connected to the bottom end of the conveying shaft 12. A discharge pipe 15 is fixedly connected to the conveying pipe 10. The first motor 14 drives the conveying shaft 12 and the spiral blade 13 to rotate. The spiral blade 13 pushes the material in the conveying pipe 10 forward until it is discharged through the discharge pipe 15, ensuring the continuity and stability of the material during the conveying process.

[0032] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the power structure 5 further includes a double-grooved pulley 501 fixed to the shaft end of one of the first crushing rollers 2, a first pulley 502 fixedly connected to the shaft end of the other first crushing roller 2, a first gear 503 provided on the rear side of the first pulley 502, the first gear 503 fixedly connected to the shaft end of the first crushing roller 2, a drive shaft 504 rotatably connected to the side wall of the crushing box 1, a second pulley 505 fixedly connected to the drive shaft 504, a second gear 506 meshing with the first gear 503 provided on the rear side of the second pulley 505, and the second pulley 505 being driven by the double-grooved pulley 501 through a first synchronous belt 507. A second motor 508 is fixedly connected to the side wall of the first crushing roller 2. A third pulley 509 is fixedly connected to the drive end of the second motor 508. The third pulley 509 is connected to the double-grooved pulley 501 via a second synchronous belt 5010. The shaft ends of the two second crushing rollers 3 are respectively fixedly connected to meshing third gears 5011. A fourth pulley 5012 is provided on the outer side of one of the third gears 5011. The fourth pulley 5012 is fixedly connected to the shaft end of the second crushing roller 3. The fourth pulley 5012 is connected to the first pulley 502 via a third synchronous belt 5013. The second motor 508 drives the third pulley 509 to rotate, which in turn drives the double-grooved pulley 501 to rotate via the second synchronous belt 5010. The double-grooved pulley 501 then drives the second pulley 505 and the coaxial second gear 506 to rotate via the first synchronous belt 507. Since the first gear 503 meshes with the second gear 506, the first gear 503 rotates accordingly, thereby driving one of the first crushing rollers 2 to rotate. At the same time, the first pulley 502 also rotates with the first gear 503, and drives the fourth pulley 5012 and a second crushing roller 3 coaxial with it to rotate through the third synchronous belt 5013. Due to the meshing transmission of the third gear 5011, the two second crushing rollers 3 rotate simultaneously, which facilitates secondary crushing of materials and facilitates complete crushing of demolished building materials.

[0033] like Figure 1 , Figure 2 and Figure 6As shown, in a preferred embodiment, based on the above method, the dust suppression structure 7 further includes a liquid storage tank 701 fixed to the upper end face of the feed hopper 6. A water pump 702 is provided on one side of the liquid storage tank 701. The water pump 702 is fixedly connected to the upper end face of the feed hopper 6. The input end of the water pump 702 is connected to the liquid storage tank 701 through a first connecting pipe 703. The output end of the water pump 702 is fixedly connected to a second connecting pipe 704. A spray pipe 705 is fixedly connected to the outer end of the second connecting pipe 704. A set of atomizing nozzles 706 are evenly fixedly connected to the spray pipe 705. The water pump 702 draws water or other dust suppression liquid from the liquid storage tank 701 and delivers it to the spray pipe 705 through the first connecting pipe 703 and the second connecting pipe 704. The water is then sprayed out by the set of atomizing nozzles 706 on the spray pipe 705 to form a fine water mist. This water mist combines with the dust generated during the crushing process, effectively suppressing the diffusion of dust and achieving the purpose of dust suppression, which is more environmentally friendly.

[0034] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, a liquid filling pipe 707 is fixedly connected to the upper end face of the liquid storage tank 701, and a screw cap is threaded to the top end of the liquid filling pipe 707. A rectangular opening is provided on the outer side wall of the liquid storage tank 701, and a transparent plate 708 is fixedly connected inside the rectangular opening. The liquid filling pipe 707 on the liquid storage tank 701 allows users to replenish the dust suppression liquid at any time, while the transparent plate 708 allows users to intuitively observe the remaining liquid in the liquid storage tank 701, ensuring the continuous and effective operation of the dust suppression system.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the angle adjustment structure 11 further includes a mounting base 1101 fixed on the crushing box 1. A telescopic cylinder 1102 is rotatably connected inside the mounting base 1101. A connecting sleeve 1103 is fixedly connected to the driving end of the telescopic cylinder 1102. A connecting block 1104 is rotatably connected inside the connecting sleeve 1103. The bottom end of the connecting block 1104 is fixedly connected to the conveying pipe 10. The telescopic extension and retraction of the telescopic cylinder 1102 and the rotatable connection between the connecting sleeve 1103 and the connecting block 1104 can flexibly adjust the tilt angle of the conveying pipe 10 to adapt to different discharge requirements or site conditions.

[0036] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, a support frame 16 is further fixedly connected to the lower end face of the crushing box 1; providing stable support for the entire device and ensuring the smooth operation of various links such as crushing, dust reduction, and conveying.

[0037] Specifically, during operation / use of this environmentally friendly building demolition crushing device: First, the second motor 508 drives the third pulley 509 to rotate, which in turn drives the double-grooved pulley 501 to rotate via the second synchronous belt 5010. The double-grooved pulley 501 then drives the second pulley 505 and the coaxial second gear 506 to rotate via the first synchronous belt 507. Since the first gear 503 meshes with the second gear 506, the first gear 503 rotates accordingly, thereby driving a first crushing roller 2 to rotate. At the same time, the first pulley 502 also rotates with the first gear 503, and drives the fourth pulley 5012 and the coaxial second crushing roller 3 to rotate via the third synchronous belt 5013. Due to the meshing transmission of the third gear 5011, the two second crushing rollers 3 rotate simultaneously. Then, they enter the crushing box 1 through the feed hopper 6, where they are first initially crushed by the first crushing roller 2 above. Subsequently, the crushed material... The material falls onto the second crushing roller 3 below for further crushing. During the crushing process, the water pump 702 is activated, drawing water or other dust-suppressing liquid from the storage tank 701 and conveying it to the spray pipe 705 through the first connecting pipe 703 and the second connecting pipe 704. The water is then sprayed out by a set of atomizing nozzles 706 on the spray pipe 705, forming a fine water mist. This water mist combines with the dust generated during the crushing process, effectively suppressing the spread of dust. When the discharge angle needs to be adjusted, the telescopic cylinder 1102 extends and retracts, and the connecting sleeve 1103 rotates with the connecting block 1104, allowing for flexible adjustment of the tilt angle of the conveying pipe 10. The crushed material enters the conveying pipe 10 through the discharge head 8 and the rotating head 9. The first motor 14 drives the conveying shaft 12 and the spiral blades 13 to rotate. The spiral blades 13 push the material in the conveying pipe 10 forward until it is discharged through the discharge pipe 15.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
