Description

Technical Field

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

[0002] Construction waste refers to various solid wastes generated during the construction, demolition, repair, and decoration of buildings. Common examples include waste concrete blocks, tiles, stone fragments, insulation materials, and plastics. To facilitate the transportation of construction waste and to recycle and reuse it, crushing devices are frequently used. However, the following problems exist in the crushing process: 1. Construction waste is usually directly fed into the crushing device, but the feed inlet is generally open. During crushing, fragments and dust can easily splash out, polluting the environment and potentially injuring workers. 2. Construction waste may contain moisture during storage. Large amounts of moisture can combine with the crushed waste to form slurry that adheres to the inside of the crushing device, increasing cleaning workload. 3. Directly feeding construction waste into the crushing device can cause it to accumulate in a certain area of ​​the crushing rollers, limiting the effective crushing area and reducing the processing capacity per unit time, thus affecting the crushing efficiency. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a crushing device for construction waste to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a crushing device for construction waste, comprising a crushing box, a feeding frame, crushing rollers, a trough plate, a perforated plate, a vibrating motor, and a first telescopic cylinder; two crushing rollers for crushing construction waste are rotatably installed inside the crushing box; the feeding frame is installed on the top of the crushing box; two trough plates are rotatably installed inside the feeding frame, and when the two trough plates are rotated to a horizontal state, they completely cover the inner side of the feeding frame; The perforated plate is detachably mounted on the top of the slot plate; The vibration motor is installed on the bottom end face of the groove plate; Below the trough plate is a first telescopic cylinder that is rotatably connected to the inside of the feed frame, and the piston rod of the first telescopic cylinder is movably connected to the trough plate. A guide assembly is provided below the first telescopic cylinder, which is used to guide construction waste to different positions on the crushing roller.

[0005] Preferably, the guiding assembly includes two baffles installed inside the crushing chamber and located below the first telescopic cylinder, a guide plate rotatably installed between the two baffles, a fixed frame detachably installed at the bottom of the baffles, and a shaft fixedly embedded in the guide plate. A second telescopic cylinder is rotatably installed inside the fixed frame, and the shaft moves through the inside of a through hole opened on the fixed frame. The piston rod of the second telescopic cylinder is movably connected to the shaft.

[0006] Preferably, a drain hose is embedded in the bottom of the tank plate, and the drain hose communicates with the inner side of the tank plate.

[0007] Preferably, the side surfaces of the groove plate and the perforated plate are flush, and both the groove plate and the perforated plate are made of stainless steel.

[0008] Preferably, the bottom end face of the guide plate and the crushing roller are spaced apart, and the guide plate swings along the length of the crushing roller.

[0009] Preferably, the through hole is an arc-shaped strip, and the through hole corresponds to the swing trajectory of the shaft.

[0010] The beneficial effects of this utility model are: This invention uses a first telescopic cylinder to rotate the trough plate to a horizontal position, sealing the feed frame and preventing construction waste from splashing out during crushing. This reduces environmental pollution from splashed waste and also prevents injury to workers from ejected waste. Furthermore, the vibration motor causes the construction waste to vibrate, causing residual moisture to fall off and pass through the perforated plate into the trough plate for storage, reducing the water content and minimizing the formation of slurry after crushing, thus reducing the workload of slurry cleaning. The guiding component directs the construction waste to different positions on the crushing roller, improving the overall utilization rate of the crushing roller and enabling the crushing of more construction waste per unit time, thereby increasing the crushing efficiency.

Detailed Implementation

[0013] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0014] like Figures 1 to 3 As shown, this utility model provides a crushing device for construction waste, including a crushing box 1, a feeding frame 2, crushing rollers 3, a trough plate 4, a perforated plate 5, a vibrating motor 6, and a first telescopic cylinder 7; two crushing rollers 3 for crushing construction waste are rotatably installed inside the crushing box 1; the top of the crushing box 1 is locked and fixed with the feeding frame 2 which guides and conveys the construction waste; two trough plates 4 are rotatably installed inside the feeding frame 2, and when the two trough plates 4 are rotated to a horizontal state, they completely cover the inner side of the feeding frame 2; The perforated plate 5 is locked and fixed to the top of the slot plate 4; The vibration motor 6 is locked and fixed to the bottom end face of the groove plate 4; A first telescopic cylinder 7 is provided below the trough plate 4 and is rotatably connected to the inside of the feed frame 2. The piston rod of the first telescopic cylinder 7 is rotatably connected to the bottom of the trough plate 4. A guide assembly is provided below the first telescopic cylinder 7. The guide assembly is used to guide the construction waste to different positions on the left and right sides of the crushing roller 3. A motor (not shown in the figure) is installed on the crushing box 1 to drive the crushing roller 3 to rotate. The first telescopic cylinder 7 is a telescopic air cylinder; The side surfaces of the groove plate 4 and the perforated plate 5 are flush, and both the groove plate 4 and the perforated plate 5 are made of stainless steel, which improves the strength of the groove plate 4 and the perforated plate 5 and allows the perforated plate 5 to cover the top of the groove plate 4, so that the moisture in the construction waste can stably pass through the perforated plate 5 and enter the groove plate 4. In this embodiment, in order to facilitate the drainage of the water collected in the tank plate 4, a drainage hose 8 is embedded at the bottom of the tank plate 4, and the drainage hose 8 is connected to the inner side of the tank plate 4. Specifically, the construction waste introduced through the feed box 2 enters the top surface of the perforated plate 5. At this time, the vibration motor 6 is started to drive the trough plate 4, the perforated plate 5 and the construction waste to vibrate. The residual water in the construction waste is vibrated and falls downwards. The water droplets pass through the perforated plate 5 and are collected in the trough plate 4. The collected water is discharged outward through the drainage hose 8 installed on the trough plate 4, thereby reducing the water content in the construction waste.

[0015] like Figure 4 and Figure 5As shown, in this embodiment, the guiding component includes two baffles 9 fixedly welded inside the crushing box 1 and located below the first telescopic cylinder 7, a guide plate 10 rotatably installed between the two baffles 9 via a rotating shaft, a fixing frame 11 locked and fixed to the bottom of the baffles 9, and a shaft 12 fixedly embedded in the lower end of the guide plate 10. A second telescopic cylinder 13 is rotatably installed inside the fixing frame 11. The shaft 12 movably passes through the inside of the through hole 14 opened on the fixing frame 11. The piston rod of the second telescopic cylinder 13 is rotatably connected to the shaft 12. The second telescopic cylinder 13 is a cylinder. The guide plate 10 mentioned above is made of stainless steel, but it can also be made of iron. The bottom end face of the guide plate 10 and the crushing roller 3 are spaced apart. The crushing roller 3 extends in the front-to-back direction, while the guide plate 10 swings in the front-to-back direction, so that the construction waste can be guided to different positions of the crushing roller 3 through the guide plate 10, thereby increasing the effective working area of ​​the crushing roller. Among them, the through hole 14 is an arc-shaped strip, and the through hole 14 corresponds to the swing trajectory of the shaft 12, which facilitates the stable movement of the shaft 12 within the through hole 14, so that the shaft 12 drives the guide plate 10 to swing stably. Specifically, by controlling the second telescopic cylinder 13 to drive the shaft 12 to swing back and forth, the shaft 12 drives the guide plate 10 to swing back and forth synchronously. After the construction waste is dewatered, by controlling the first telescopic cylinder 7 to drive the trough plate 4 to rotate downward, the two trough plates 4 rotate to an inclined state and separate from each other, so that a gap appears between the two trough plates 4. The construction waste is discharged downward through the gap. The construction waste is affected by the swinging guide plate 10 and falls to different positions in the front and back directions of the crushing roller 3. Then, the rotating crushing roller 3 crushes the construction waste. In the process of crushing construction waste by the crushing roller 3, the first telescopic cylinder 7 drives the trough plate 4 and the perforated plate 5 to rotate upward and seal the feed frame 2, preventing dust and fragments from being ejected outward through the feed frame 2. At this time, the next batch of construction waste to be crushed can be introduced into the top of the perforated plate 5, and the second batch of construction waste can be dehydrated by the vibration motor 6, thereby pre-treating the second batch of construction waste by dehydration. This makes it easier for the second batch of construction waste to directly enter the crushing box 1 for crushing after the first batch of construction waste has been crushed, thus improving the continuity of the overall operation of the crushing device.
