Description

Technical Field

[0001] This invention belongs to the field of construction waste treatment technology, and specifically relates to a construction waste crushing device. Background Technology

[0002] With rapid urban renewal and expanding building scale, the generation and discharge of construction waste are also increasing rapidly. Large amounts of construction waste are generated at construction sites, and in underdeveloped areas and cities, most of this waste is directly transported to the suburbs or countryside for open dumping or landfill. If this waste is not treated or recycled, it will cause environmental pollution. Therefore, the demand for construction waste recycling equipment is growing. To improve the recycling efficiency of construction waste, it is usually necessary to first crush the waste. Because construction waste fragments vary in size, large-scale crushing equipment is required. However, large equipment is limited by terrain and its use is inconvenient. Small equipment is difficult to process waste with large volume differences, requiring repeated processing and resulting in low efficiency. Summary of the Invention

[0003] Based on the problems mentioned in the background art above, the present invention provides a construction waste crushing device to solve the problems that large equipment is greatly restricted by terrain and its use is not fixed, while small equipment is difficult to process waste with large volume differences, requiring repeated processing and resulting in low processing efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A construction waste crushing device includes a main frame, on which a traveling mechanism and a crushing mechanism are mounted. The crushing mechanism includes a crushing bucket mounted on the main frame, with two opposing crushing rollers installed inside the crushing bucket. The two crushing rollers are respectively driven and connected to a first motor. A first mounting plate is provided on the main frame, and the two first motors are respectively mounted on the first mounting plate. A feeding mechanism is mounted above the crushing mechanism, and the feeding mechanism includes a base connected to the main frame. A housing is provided on the base, and a second mounting plate is provided inside the housing. A crushing assembly is installed inside the housing, and the crushing assembly includes a crankshaft mounted above the second mounting plate. A plurality of cranks are mounted on the crankshaft. A guide cylinder corresponding to the cranks is provided on the second mounting plate. A slider is hinged to the end of each crank and slides within the guide cylinder. Each slider is equipped with a crushing cone rod. A second motor is driven and connected to the crankshaft, and the second motor is mounted on the first mounting plate.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, the number of crushing components is at least two sets. The length of the crushing cone on the crushing component gradually decreases from the feeding end to the discharge end of the feeding mechanism. Adjacent crushing components are connected by crankshaft drive, and the crankshaft of any crushing component is connected to a second motor drive. By using multiple sets of crushing components with varying crushing cone lengths in combination, the material can be crushed from large to small, which helps to improve crushing capacity, resulting in a smaller volume of material falling into the crushing hopper at the end, allowing the crushing rollers to crush the material quickly.

[0008] Furthermore, a feeding assembly is installed on the base. The feeding assembly includes two rotating shafts, each with a first gear. A transmission chain is installed between the first gears at the ends of the two rotating shafts. Multiple push rods are installed at equal intervals between the two transmission chains. The base has a first reserved slot corresponding to the transmission chain and a second reserved slot. The rotating shafts are mounted on the base, and the first gears are located in the second reserved slots. A drive wheel is installed at one end of each rotating shaft, and the drive wheel is connected to a first motor. When the feeding assembly is running, the transmission chain can drive the push rods to move, which can agitate the broken pieces on the base, making it easier for the broken pieces to slide into the crushing hopper.

[0009] Furthermore, a material transfer mechanism is installed on the main frame. This mechanism includes two sets of support wheels, with a screen cylinder installed between them. The screen cylinder has track grooves corresponding to the support wheels, allowing it to rotate. The screen cylinder is fitted around the outside of the crushing hopper. Several material transfer plates are installed inside the screen cylinder. The crushing hopper has notches corresponding to the material transfer plates. A gear ring is located at one end of the screen cylinder. A driven wheel is installed on the main frame, and it is connected to a first motor. A second gear is coaxially connected to the driven wheel, meshing with the gear ring. The rotation of the screen cylinder allows it to collect the fragments that have fallen after being crushed by the two crushing rollers. During the rotation, the fragments are screened, and fragments with a volume larger than the through-holes in the screen cylinder are re-input into the crushing hopper for further crushing.

[0010] Furthermore, a top material roller is installed between the support wheels in the same group, and the top material roller is in tangential contact with the screen cylinder. During the rotation of the screen cylinder, the top material roller presses against the surface of the screen cylinder, which can push out the gravel embedded in the through holes of the screen cylinder and prevent the screen cylinder from being blocked.

[0011] Furthermore, a metal separator is installed on the main frame below the screen cylinder. The metal separator includes a support, on which a first magnetic plate is mounted. The first magnetic plate is U-shaped. Guide pulleys and guide rollers are respectively installed at both ends of the support. The guide pulleys are located on both sides of the first magnetic plate. A conveyor belt is installed between the guide pulleys and the guide rollers. The first magnetic plate is located at the discharge end of the conveyor belt and contacts the inner wall of the conveyor belt. A second magnetic plate is connected to the bottom end of the first magnetic plate. The second magnetic plate gradually tilts upward away from the first magnetic plate and separates from the conveyor belt. When the conveyor belt moves the crushed waste material through the area where the first magnetic plate is located, the metal in the crushed stone can be adsorbed onto the surface of the conveyor belt, thereby separating the metal from the crushed stone. As the second magnetic plate gradually moves away from the conveyor belt, the magnetic field on the surface of the conveyor belt gradually decreases. The separated metal gradually leaves the conveyor belt from the largest to the smallest volume. While stripping the metal, it can also separate metals of different volumes according to their weight.

[0012] Furthermore, a bracket is installed on the main frame, and a storage box is installed on the bracket. The storage box is located below the conveyor belt, and a limit block is installed on the bracket. The storage box has multiple storage cavities. The storage box collects fallen metal, facilitating metal recycling.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. It can crush construction waste for recycling and reuse, which helps reduce resource waste;

[0015] 2. By setting up a feeding mechanism, larger pieces of construction waste can be crushed before entering the crushing hopper, preventing larger pieces of stone from falling directly into the crushing hopper. This would prevent the crushing rollers from being able to bite larger pieces immediately when rotating, causing large pieces to roll between the two crushing rollers and affecting the crushing efficiency. This results in high stone processing efficiency. Attached Figure Description

Detailed Implementation

[0029] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figures 1-4 , Figure 10 As shown, a construction waste crushing device includes a main frame 1, on which a traveling mechanism 11 and a crushing mechanism are mounted. In this embodiment, the traveling mechanism 11 is a tracked mechanism, enabling the waste crushing device to move better in environments with poor ground conditions. The crushing mechanism includes a crushing bucket 13 mounted on the main frame 1, with two opposing crushing rollers 14 installed inside the crushing bucket 13. The two crushing rollers 14 are respectively driven by a first motor 15, which drives the two crushing rollers 14 to rotate. The large clamping force of the two crushing rollers 14 enables better crushing of the waste. A first mounting plate 12 is provided on the main frame 1, and the two first motors 15 are respectively mounted on the first mounting plate 12. A feeding mechanism 3 is mounted above the crushing mechanism.

[0032] like Figure 4 As shown, the feeding mechanism 3 includes a base 31 connected to the main base frame 1. The waste material to be crushed is first placed on the base 31, and then slides into the crushing hopper 13 along with the upper surface of the base 31. The base 31 is inclined so that the powder can slide into the crushing hopper 13 more smoothly. A box 32 is provided on the base 31, and a second mounting plate 33 is provided inside the box 32. A crushing assembly is installed inside the box 32. The crushing assembly includes a crankshaft 35 installed above the second mounting plate 33. Several cranks 36 are installed on the crankshaft 35. A guide cylinder 34 corresponding to the cranks 36 is provided on the second mounting plate 33. A slider is hinged to the end of the crank 36. When the crankshaft 35 rotates, the slider can be driven to move up and down in the guide cylinder 34 through the cranks 36. The slider slides and is transmitted into the guide cylinder 34. Each slider is equipped with a crushing cone rod 37. The crushing cone rod 37 moves up and down with the slider to break the crushed stone blocks below, thereby crushing larger waste blocks. The crankshaft 35 is connected to the second motor 38, which is mounted on the first mounting plate 12.

[0033] In this embodiment, there are two sets of crushing components. The length of the crushing cone 37 on the crushing component gradually decreases from the feeding end of the feeding mechanism 3 to the discharging end. The crankshafts 35 of adjacent crushing components are connected by transmission. The crankshaft 35 of any crushing component is connected by transmission to the second motor 38. By using multiple sets of crushing components with varying crushing cone 37 lengths in combination, the material can be crushed from large to small, which is beneficial to improving the crushing capacity and making the volume of the material falling into the crushing hopper 13 smaller, so that the crushing roller 14 can crush it quickly.

[0034] like Figures 4-7 As shown, a feeding assembly 4 is installed on the base 31. The feeding assembly 4 includes two rotating shafts 41, each with a first gear 42. A transmission chain 43 is installed between the first gears 42 at the ends of the two rotating shafts 41. Multiple push rods 44 are installed at equal intervals between the two transmission chains 43. A first reserved slot 311 corresponding to the transmission chain 43 is provided on the base 31. A second reserved slot 312 is provided on the base 31. The rotating shafts 41 are installed on the base 31, and the first gears 42 are located in the second reserved slot 312. A drive wheel 45 is installed at one end of any rotating shaft 41. The drive wheel 45 is connected to the first motor 15. When the feeding assembly 4 is running, it can drive the push rods 44 to move through the transmission chain 43. During the movement, the push rods 44 located above the base 31 can push the broken pieces on the base 31, making it easier for the broken pieces to slide into the crushing hopper 13.

[0035] like Figure 8 , Figure 9As shown, two sets of support wheels 22 are installed on the main frame 1, and a screen cylinder 23 is installed between the two sets of support wheels 22. The screen cylinder 23 is provided with a track groove 231 corresponding to the support wheels 22. The track groove 231 is mounted on the support wheels 22 to allow the screen cylinder 23 to rotate. The screen cylinder 23 is fitted outside the crushing hopper 13. The crushed material after being crushed by the two crushing rollers 14 can fall directly into the screen cylinder 23. Several rotating plates 24 are installed inside the screen cylinder 23. The crushing hopper 13 is provided with a notch 131 corresponding to the rotating plate 24. This notch reduces the distance between the end of the rotating plate 24 and the crushing hopper 13 while preventing the crushing hopper 13 from obstructing the movement of the rotating plate 24, so that the crushed material in the screen cylinder 23 can fall into the crushing hopper 13 better. One end of the screen cylinder 23 is equipped with a gear ring 232. A driven wheel 25 is mounted on the main frame 1. The driven wheel 25 is connected to the first motor 15 for transmission. The driven wheel 25 is coaxially connected to a second gear 26, which meshes with the gear ring 232. When the screen cylinder 23 rotates, it can catch the fragments that fall after being crushed by the two crushing rollers 14. During the rotation of the screen cylinder 23, the fragments are screened, and the fragments with a volume larger than the through holes on the screen cylinder 23 are put back into the crushing hopper 13 for further crushing. Among them, a top material roller 21 is installed between the support rollers 22 in the same group. The top material roller 21 is in tangential contact with the screen cylinder 23. During the rotation of the screen cylinder 23, the top material roller 21 presses the surface of the screen cylinder 23, which can push out the stone fragments embedded in the through holes on the screen cylinder 23 and prevent the screen cylinder 23 from being blocked.

[0036] like Figure 11 As shown, a metal separator 5 is installed on the main frame 1 below the screen cylinder 23. The metal separator includes a support 51, on which a first magnetic piece 53 is installed. The first magnetic piece 53 is U-shaped. Guide rollers and guide pulleys are respectively installed at both ends of the support 51. The guide rollers are located on both sides of the first magnetic piece 53. A conveyor belt 52 is installed between the guide rollers and the guide pulleys. The first magnetic piece 53 is located at the discharge end of the conveyor belt 52 and contacts the inner wall of the conveyor belt 52. A second magnetic piece 54 is connected to the bottom end of the first magnetic piece 53. The second magnetic piece 54 gradually tilts upward away from the first magnetic piece 53 and separates from the conveyor belt 52. When the conveyor belt 52 moves the crushed waste along the conveyor belt 52, the area equipped with the first magnetic plate 53 can attract metal from the crushed stone to the surface of the conveyor belt 52, thereby separating the metal from the crushed stone. As the second magnetic plate 54 gradually moves away from the conveyor belt 52, the magnetic field on the surface of the conveyor belt 52 gradually decreases, and the separated metal gradually leaves the conveyor belt 52 from largest to smallest volume. This not only strips the metal but also separates metals of different volumes according to their weight. A bracket 60 is installed on the main base frame 1, and a collection box 6 is installed on the bracket 60. The collection box 6 is located below the conveyor belt 52, and a limit block 601 is installed on the bracket 60. The collection box 6 has multiple collection cavities 61. The collection box 6 collects the fallen metal, facilitating metal recycling.

[0037] During operation, the construction waste to be processed is fed onto the base 31. As the feeding assembly 4 operates, the transmission chain 43 drives the pusher rod 44 to move, conveying the waste located above the base 31 into the crushing hopper 13. The crankshaft 35, rotating in the middle, drives the slider to move up and down in the guide cylinder 34 via the crank 36, thereby driving the crushing cone rod 37 to move up and down reciprocally to crush the waste blocks. After crushing, the fragments fall into the crushing hopper 13 and are further crushed by the crushing roller 14. The processed waste falls into the screen cylinder 23, where it is screened after being processed by the crushing roller 14. The crushed material that cannot pass through the screen holes of the screen cylinder 23 can fall back into the crushing hopper 13 for further processing as the screen cylinder 23 rotates. The crushed material that passes through the screen cylinder 23 falls onto the conveyor belt 52 and moves with it. When it passes the first magnetic plate 53, the metal in the crushed material is adsorbed onto the surface of the conveyor belt 52, thereby separating the metal from the crushed stone. As the second magnetic plate 54 gradually moves away from the conveyor belt 52, the magnetic field on the surface of the conveyor belt 52 gradually decreases. The separated metal gradually leaves the conveyor belt 52 from the largest to the smallest volume. Metals of different volumes can be graded and separated according to their weight. The separated metal falls into the storage box 6.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
