Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste concrete recycling technology, and in particular to a waste concrete crushing box. Background Technology
[0002] With the booming development of the construction industry, a large number of building demolition and new construction projects are emerging, resulting in a sharp increase in the amount of waste concrete. If this waste concrete is not properly handled, it will cause negative impacts on the surrounding environment, such as soil and water pollution. Therefore, the resource-based reuse of waste concrete has become a key link in achieving sustainable development in the construction field. In the resource-based treatment of waste concrete, crushing is an extremely important preliminary step.
[0003] A search revealed Chinese Patent Publication No. CN222093453U, which discloses a waste concrete crushing device. The device includes a shell, with a feed inlet fixedly connected to the upper end of the shell. A crushing wheel and a grinding wheel are rotatably connected to the inner wall of the shell. Gears are fixedly installed at one end of each crushing wheel and grinding wheel, meshing with each other. A motor is fixedly installed at the outer end of the shell, with one end of the motor fixedly installed between the motor and the gear. A conveying pipe is fixedly installed on the inner wall of the shell, with a conveying rod rotatably connected to its inner wall. A second motor is fixedly installed at the upper end of the conveying pipe. This invention utilizes the action of a spring inside the shell to return the screening plate to its original position after being struck by the crushed concrete, facilitating the screening of the crushed concrete. By starting the second motor, the conveying rod rotates, transporting some of the screened concrete back to the feed inlet for further crushing, ensuring complete pulverization of the concrete. However, in actual use, the spacing between the crushing rollers of the waste concrete crushing device is fixed, which can cause the device to jam when dealing with waste concrete of different block shapes. This makes it difficult for the device to rotate normally and affects the crushing efficiency. To address this issue, a waste concrete crushing box is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a waste concrete crushing box, which aims to improve the problem in the prior art where the crushing roller jams and the device is difficult to rotate normally when facing waste concrete with different block shapes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste concrete crushing box, comprising a box body and a spiral return device, wherein a servo motor is fixedly connected to the front side of the box body, the output end of the servo motor passes through the front side of the box body and is fixedly connected to a crushing roller, a cylinder is fixedly connected to the left side of the box body, one end of the cylinder passes through the left side of the box body and is fixedly connected to a moving frame, and sliding grooves are provided on both the front and rear sides of the box body, with limiting sliders slidably connected inside the two sliding grooves, and the two limiting sliders are fixedly connected to the front and rear sides of the moving frame, a servo motor is fixedly connected to the front side of the limiting slider on the front side, the output end of the servo motor passes through the front side of the moving frame and is fixedly connected to a crushing roller, and limiting rods are slidably connected to the left side of the box body, the right ends of the two limiting rods pass through the left side of the box body and are fixedly connected to the left side of the moving frame, a screening component is provided inside the box body, a secondary crushing component is provided inside the box body, and a dust collection mechanism is provided on the left side of the box body.
[0006] The above technical solution involves starting servo motor one and servo motor two to drive crushing roller one and crushing roller two to rotate in opposite directions, thereby crushing waste concrete. When crushing roller one and crushing roller two encounter a large piece of concrete and get stuck, the cylinder is activated to drive the moving frame to slide to the left, adjusting the distance between them to loosen and remove the blocking concrete. The concrete then falls into the spiral return material equipment and is transported back for secondary crushing, greatly avoiding the problem of equipment jamming.

A collection bag is connected to the bottom of the filter box.
[0009] The above technical solution involves installing suction plates around the top of the housing. By activating the vacuum cleaner, negative pressure is created inside the filter box. Dust generated during crushing and screening enters the filter box through the suction pipe. The vacuum cleaner then removes excess air, while the dust in the air is filtered by the filter plates. To avoid frequent cleaning of the filter plates, an electric push rod drives a scraper to remove dust from the surface of the filter plates. Finally, the dust flows into a collection bag through the bottom sloping groove of the filter box for storage, facilitating subsequent cleaning.

[0011] The screening assembly includes a vibration motor, which is fixedly connected to the right side of the housing, and a screening plate is fixedly connected to the middle of the inner side of the housing.
[0012] Through the above technical solution: the waste concrete after primary crushing will fall onto the screening plate, and through the repeated shaking of the vibrating motor, the small qualified particles will fall down and enter the secondary crushing; at the same time, the unqualified particles will slide to the right and finally be conveyed upwards again through the spiral return equipment.
[0013] As a further description of the above technical solution:
[0014] The secondary crushing assembly includes two fine crushing rollers, which are rotatably connected to the lower inner part of the housing. A servo motor is fixedly connected to the front side of the housing, and the output end of the servo motor passes through the front side of the housing and is fixedly connected to the front end of the fine crushing rollers.
[0015] Through the above technical solution, the sieved particles are finely ground by fine grinding rollers and finally become powder for storage, which is convenient for subsequent processing and use.
[0016] As a further description of the above technical solution:
[0017] An inclined plate one is fixedly connected to the left and right sides inside the box, and an inclined plate two is fixedly connected to the left and right sides inside the box.
[0018] The above technical solution involves setting inclined plates one and two on the upper and lower sides of the inside of the box, respectively, which facilitates centralized guidance of materials and improves accuracy.
[0019] As a further description of the above technical solution:
[0020] The outer wall of the spiral return equipment is fixedly connected to a reinforcing plate, and the left side of the reinforcing plate is fixedly connected to the right side of the box.
[0021] The above technical solution involves connecting the spiral recirculation equipment to the housing using a reinforcing plate, which ensures the stability of the spiral recirculation equipment during operation.
[0022] As a further description of the above technical solution:
[0023] A controller is fixedly connected to the front of the housing. The controller is electrically connected to the vacuum cleaner, electric push rod, servo motor one, cylinder, servo motor two, servo motor three, spiral return equipment and vibrating motor respectively.
[0024] The above technical solution allows for convenient and simple operation and control of the operating equipment throughout the entire device via a controller.
[0025] As a further description of the above technical solution:
[0026] A support frame is fixedly connected to the bottom of the box, and a rubber pad is fixedly connected to the bottom end of the support frame. A collection box is slidably connected to the top of the support frame.

[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, when the crushing roller one and the crushing roller two become stuck, the moving frame slides left and right under the drive of the cylinder, so as to adjust the distance between the crushing roller one and the crushing roller two, thereby loosening and removing the blockage concrete, which then falls into the spiral return material equipment and is transported back for secondary crushing, greatly avoiding the problem of equipment jamming.
[0030] 2. In this utility model, the vacuum cleaner creates negative pressure inside the filter box, allowing dust to enter the filter box through the suction pipe. The vacuum cleaner then removes excess air and filters the dust from the air through the filter plate. When the filter plate becomes clogged, the electric push rod is activated to push the scraper up and down, causing the scraped dust to fall into the collection bag for easy cleaning later.

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.
[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a waste concrete crushing box, including a box body 1 and a spiral return device 15. A servo motor 3 is fixedly connected to the front side of the box body 1. The output end of the servo motor 3 passes through the front side of the box body 1 and is fixedly connected to a crushing roller 4. The servo motor 3 can drive the crushing roller 4 to rotate, so that the crushing roller 4 can crush the concrete. A cylinder 5 is fixedly connected to the left side of the box body 1. One end of the cylinder 5 passes through the left side of the box body 1 and is fixedly connected to a moving frame 6. Slide grooves 8 are opened on both the front and rear sides of the box body 1. Limiting sliders 9 are slidably connected inside the two slide grooves 8. The limiting slider 9 is fixedly connected to the front and rear sides of the movable frame 6. The movable frame 6 and the limiting slider 9 are integrally formed. Under the limiting action of the slide groove 8, the limiting slider 9 enables the movable frame 6 to slide stably left and right. A servo motor 10 is fixedly connected to the front side of the front limiting slider 9. The servo motor 10 is supported by the limiting slider 9. The output end of the servo motor 10 passes through the front side of the movable frame 6 and is fixedly connected to the crushing roller 11. It also passes through the limiting slider 9 and is fixed to the crushing roller 11. By starting the servo motor 10, the crushing roller 11 is driven to rotate. At this time, the crushing roller 1 and the crushing roller 2... The relative rotation of rollers 11 enables rapid crushing of concrete. The moving frame 6, driven by cylinder 5, slides left and right, adjusting the distance between crushing roller 4 and crushing roller 11 for easy and rapid clearing of concrete. Limiting rods 12 are slidably connected to the left side of the box body 1. The right ends of the two limiting rods 12 penetrate the left side of the box body 1 and are fixedly connected to the left side of the moving frame 6. The limiting rods 12 provide stable support and limit the movement of the moving frame 6 using the box body 1. A screening assembly and a secondary crushing assembly are installed inside the box body 1. A dust collection mechanism 2 is located on the left side of the box body 1. The screening assembly includes... A vibrating motor 16 is fixedly connected to the right side of the housing 1. A screening plate 14 is fixedly connected to the middle of the inner side of the housing 1. The crushed concrete falls onto the screening plate 14 and is further subdivided by the vibrating motor 16. The secondary crushing component includes two subdividing rollers 19, which are rotatably connected to the lower middle part of the inner side of the housing 1. A servo motor 18 is fixedly connected to the front side of the housing 1. The output end of the servo motor 18 passes through the front side of the housing 1 and is fixedly connected to the front end of the subdividing rollers 19. Finally, the subdividing rollers 19 further crush the screened concrete into powder, thus achieving the processing.
[0040] Specifically, servo motor 3 drives crushing roller 4 to rotate to complete the concrete crushing operation. The moving frame 6 and the limiting slider 9 are integrally molded. Under the constraint of the sliding groove 8, the limiting slider 9 ensures that the moving frame 6 can slide smoothly left and right. Servo motor 10 is supported by the limiting slider 9. Its output end passes through the front side of the moving frame 6 and fixes crushing roller 11. It also passes through the limiting slider 9 and fixes it. After the servo motor 10 is started, crushing roller 11 rotates accordingly. In this way, crushing roller 4 and crushing roller 11 rotate relative to each other, efficiently crushing concrete. At the same time, the moving frame 6 slides left and right under the action of cylinder 5 to adjust the distance between crushing roller 4 and crushing roller 11, which facilitates the rapid clearing of concrete. The limiting rod 12 uses the box 1 to limit and stabilize the moving frame 6. The crushed concrete falls onto the screening plate 14. The vibrating motor 16 works with the screening plate 14 to subdivide the concrete. Finally, the subdivided concrete is further crushed by the subdividing roller 19 to turn it into powder, thus completing the processing.
[0041] Reference Figure 1 , Figure 3 and Figure 5 The dust collection mechanism 2 includes a dust collection plate 201, which is fixedly connected to the top of the housing 1. The dust collection plate 201 is arranged around the top of the housing 1, which allows for more comprehensive dust collection from all sides. A dust collection pipe 202 is connected to the left side of the dust collection plate 201, and the other end of the dust collection pipe 202 is connected to a filter box 203. A filter plate 204 is fixedly connected to the front of the inside of the filter box 203, and a vacuum cleaner 205 is connected to the front of the filter box 203. By activating the vacuum cleaner 205, a negative pressure is created inside the filter box 203, and dust enters through the dust collection pipe 202. The filter box 203 contains a vacuum cleaner 205 to remove excess air and a filter plate 204 to filter dust. An electric push rod 206 is fixedly connected to the top front of the filter box 203. One end of the electric push rod 206 passes through the top of the filter box 203 and is fixedly connected to a scraper 207. When the filter plate 204 becomes clogged, the electric push rod 206 is activated to push the scraper 207 to slide up and down. The bottom of the filter box 203 is connected to a collection bag 208. The scraped dust falls into the collection bag 208 for easy cleaning later.
[0042] Specifically, the suction plate 201 is located on the top edge of the housing 1, surrounding the perimeter to ensure more comprehensive dust collection from the surrounding environment. The left side of the suction plate 201 is connected to the suction pipe 202, while the other end of the suction pipe 202 is connected to the filter box 203. A filter plate 204 is fixedly installed inside the front of the filter box 203, and the front of the filter box 203 is connected to the vacuum cleaner 205. By activating the vacuum cleaner 205, a negative pressure environment is created inside the filter box 203, allowing dust to be sucked into the filter box 203 through the suction pipe 202. Simultaneously, the suction... The filter 205 also expels excess air, while the filter plate 204 is responsible for effectively filtering dust in the passing air. An electric push rod 206 is fixed at the top front of the filter box 203. One end of the electric push rod 206 passes through the top of the filter box 203 and is fixed to the scraper 207. When the filter plate 204 is clogged, the electric push rod 206 can be activated to push the scraper 207 to slide up and down to clear the blockage. The bottom of the filter box 203 is connected to the collection bag 208, so the scraped dust will fall into the collection bag 208 for easy subsequent cleaning.
[0043] Reference Figure 1 , Figure 2 and Figure 3 Inclined plates 13 are fixedly connected to the left and right sides inside the box 1, and inclined plates 20 are fixedly connected to the left and right sides inside the box 1. A reinforcing plate 17 is fixedly connected to the outer wall of the spiral return equipment 15. The left side of the reinforcing plate 17 is fixedly connected to the right side of the box 1. A controller 7 is fixedly connected to the front of the box 1. The controller 7 is electrically connected to the vacuum cleaner 205, the electric push rod 206, the servo motor 3, the cylinder 5, the servo motor 10, the servo motor 18, the spiral return equipment 15, and the vibration motor 16. The controller 7 facilitates simple operation and control of the operating equipment on the entire device. A support frame 21 is fixedly connected to the bottom of the box 1. Rubber pads 22 are fixedly connected to the bottom of the support frame 21. A collection box 23 is slidably connected to the top of the support frame 21. The processed and crushed concrete is collected through the collection box 23 for easy subsequent transportation.
[0044] Specifically, the controller 7 allows for convenient and simple operation control of the equipment throughout the device, greatly improving work efficiency and ease of operation. To ensure stable operation of the equipment, a support frame 21 is fixed to the bottom of the housing 1, and rubber pads 22 are fixed to the bottom of each support frame 21. These rubber pads 22 can effectively absorb vibration, reduce noise generated during equipment operation, and protect the ground from damage. A collection box 23 slides on the top of the support frame 21, and the crushed concrete is collected through the collection box 23. This not only facilitates the collection of materials but also makes subsequent transportation and processing easier, improving the efficiency of the entire production process.
[0045] Working principle: First, servo motor 13 and servo motor 210 are started to drive crushing roller 14 and crushing roller 21 to rotate in opposite directions, realizing the rapid crushing of waste concrete. When crushing roller 14 and crushing roller 21 are facing a large piece of concrete and jamming occurs, the moving frame 6 slides left and right under the drive of cylinder 5 to adjust the distance between crushing roller 14 and crushing roller 21, thereby loosening and removing the blockage of concrete. Then, it falls into the spiral return material device 15 and is transported back for secondary crushing, which greatly avoids the problem of equipment jamming. The crushed concrete falls onto the screening plate 14, and the vibrating motor 16 further subdivides the concrete. Finally, the screened concrete is further crushed into powder by the subdividing roller 19, thus realizing the processing.
[0046] Furthermore, by activating the vacuum cleaner 205, a negative pressure is created inside the filter box 203. Dust enters the filter box 203 through the suction pipe 202, and excess air is expelled by the vacuum cleaner 205. The dust in the air is filtered by the filter plate 204. When the filter plate 204 becomes clogged, the electric push rod 206 is activated to push the scraper 207 to slide up and down, and the scraped dust falls into the collection bag 208 for easy cleaning later.
