Description

Technical Field

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

[0002] Construction waste contains a large amount of concrete blocks, brick and tile fragments, metals, etc. After processing, these materials can be reused as recycled resources in construction projects, such as being made into recycled aggregates for road base materials. By using waste cleaning equipment to sort and crush construction waste, the resource recycling rate can be improved, the construction industry's demand for resources can be met, and the dependence on raw materials such as natural sand and gravel can be reduced, resulting in significant economic and environmental benefits. During the construction waste cleaning process, the feeding speed is very fast. When large pieces of material and oversized materials that have not been pre-treated are put into the crushing chamber, these materials are very likely to get stuck between the moving cone and the fixed cone or at the feed inlet. Large pieces of material such as oversized concrete blocks and bricks stuck in the crushing chamber will continuously block the crushing channel, forcing the crushing components to stop rotating. This not only causes the entire equipment to stop and interrupts the waste processing process, but may also damage the transmission components, seriously affecting the work efficiency. Therefore, we propose a construction waste cleaning equipment. Summary of the Invention

This drives the fixed cone to rise synchronously, and the clamping plate rises along the slide groove of the support plate. During this process, the limiting plate presses against the contact plate, compressing the first tension spring. The contact plate pushes the ear plate to rotate downwards around the fixed rod, pulling the telescopic rod to compress the second tension spring to contract. When the movable housing with the external thread groove is in place, the clamping plate disengages from the limiting plate.

With the reinforcement of the thread teeth and thread groove, the crushing distance can be stably locked. This allows for flexible adjustment of the gap between the moving and fixed cones to adapt to the processing needs of different specifications of construction waste, while also ensuring the safe and stable operation of the equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-11 As shown, the present invention provides a technical solution: a construction waste cleaning device, including a box assembly 1 for temporary storage of feed, a particle size adjustment assembly 2 and a crushing assembly 3 are arranged inside the box assembly 1, a moving cone 306 and a fixed cone 308 are arranged inside the crushing assembly 3, the particle size adjustment assembly 2 is used to adjust the size of the gap between the moving cone 306 and the fixed cone 308, a crushing assembly 4 is assembled at the lower end of the crushing assembly 3 for further crushing after crushing the crushing assembly 3, and a screening assembly 5 is assembled at the lower end of the crushing assembly 4 for screening after crushing the crushing assembly 4; Furthermore, construction waste enters the housing assembly 1 through the feed hopper 105 and naturally falls into the crushing chamber of the crushing assembly 3 during temporary storage. The crushing assembly 3 first performs preliminary filtration of the material, removing oversized debris that may damage the equipment. Subsequently, the moving cone 306 rotates under power drive, forming a periodically changing compression space with the fixed cone 308. Large pieces of material are crushed under the action of compression and grinding, and finally discharged from the gap between the two. When it is necessary to process large pieces of material, the operator can pull the handle 104 upward to move the external threaded groove movable housing 102 upward. With the coordinated cooperation of the various components of the particle size adjustment assembly 2, the gap between the moving cone 306 and the fixed cone 308 can be increased. Through the adjustment mechanism, the gap can be flexibly changed according to the particle size requirements of the target product, thereby determining the crushing assembly. The discharge particle size of component 3 ensures that large pieces of material can pass smoothly and avoids material jamming. After primary crushing, the material falls into crushing component 4 by gravity. This component rotates under power and performs secondary crushing of the material through shearing and crushing action, which can refine the particles to a smaller size, effectively making up for the uneven particle size problem in primary crushing, making the material crushed more uniformly and finer, and significantly improving the overall crushing effect. The finely crushed material enters screening component 5. During the screening process, the grinding function of screening component 5, on the one hand, further crushes the material, making the particle size of the material further reduced, ensuring that it can pass smoothly through the discharge hopper 107 and be discharged. On the other hand, through grinding and scraping, it prevents material particles from clogging the screen holes, ensuring a smooth and efficient screening process, and finally outputting material that meets the requirements.

[0019] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the housing assembly 1 includes an upper crushing box 101. An externally threaded groove movable housing 102 is movably mounted on the inner wall of the upper crushing box 101. The inner diameter of the externally threaded groove movable housing 102 has a threaded groove. An externally threaded tooth fixing housing 103 is movably mounted on the inner wall of the externally threaded groove movable housing 102. The outer diameter of the externally threaded tooth fixing housing 103 is provided with threaded teeth, which mesh with the threaded groove. Handles 104 are fixedly mounted on both sides of the upper end of the externally threaded groove movable housing 102. Two handles 104 are provided. A feed hopper 105 is fixedly installed at one end of the upper crushing box 101, and a lower crushing box 106 is fixedly installed at the lower end of the upper crushing box 101. A discharge hopper 107 is fixedly installed at the lower end of the lower crushing box 106. The particle size adjustment component 2 includes a groove 201, which is formed on the inner side wall of the upper crushing box 101. There are two grooves 201. A support plate 202 is fixedly connected to one side of each groove 201 near the external threaded groove movable housing 102. A sliding groove structure is formed on both sides of each support plate 202. A retaining plate 2 is movably sleeved on the outside of each support plate 202. 03. The two clamping plates 203 and the external threaded groove movable housing 102 are all integral structures. A limit plate 204 is fixedly connected to one side of each of the two clamping plates 203. Several sleeves 205 are provided inside each of the two grooves 201. A slot is opened on one side of each sleeve 205, and a contact plate 206 is provided inside the slot. A telescopic rod 207 is movably connected to the inner wall of each sleeve 205. An ear plate 208 is rotatably connected to the bottom end of the telescopic rod 207 near the center of the inner wall of the sleeve 205. One end of the ear plate 208 is connected to the telescopic rod 205 by bolts. 7. A fixing rod 209 is fixedly connected to the lower end of the inner wall of the sleeve 205 near the telescopic pull rod 207. The fixing rod 209 is connected to the other end of the ear plate 208 by bolts. A fixing block 2010 is fixedly connected to the upper end of the fixing rod 209 near the telescopic pull rod 207. A tension spring 2011 is connected to the inner side of the fixing block 2010 near the slot. The tension spring 2011 is located behind the contact plate 206. A tension spring 2012 is connected to the lower end of the telescopic pull rod 207 near the bottom end of the inner wall of the sleeve 205. Furthermore, when large pieces of material need to be processed, the operator pulls the handle 104 upwards. The movable housing 102 with external thread groove moves upwards by engaging with the threads of the fixed housing 103 with external thread groove, simultaneously driving the fixed cone 308 to rise synchronously. The clamping plate 203 also rises along the sliding groove of the support plate 202. During this process, the limiting plate 204 rises with the clamping plate 203 and presses against the contact plate 206, causing the tension spring 2011 to compress. Since the contact plate 206 is attached to the upper part of the ear plate 208, the squeezing force generated when it moves into the sleeve 205 forces the front end of the ear plate 208 to rotate downwards around the fixed rod 209. The greater the force of pulling the handle 104, the deeper the contact plate 206 enters the sleeve 205, and the greater the downward rotation angle of the ear plate 208, which in turn pulls the telescopic rod 207 to compress the tension spring 209. The second extension spring 2012 retracts into the sleeve 205. When the external threaded groove movable housing 102 is adjusted to the target position, after the clamping plate 203 and the limiting plate 204 disengage, the compressive force of the first extension spring 2011 decreases sharply, which will instantly push the contact plate 206 to move outward from the groove. At the same time, the second extension spring 2012 drives the telescopic rod 207 to return to its original position. At this time, the limiting plate 204 will be engaged on both sides of the telescopic rod 207 to fix the position of the external threaded groove movable housing 102 and prevent the clamping plate 203 from shifting. In addition, the external threaded groove movable housing 102 and the external threaded tooth fixed housing 103 further enhance the structural stability through the meshing of the screw teeth and screw groove, thereby stably locking the currently adjusted crushing distance, which not only meets the processing needs of construction waste of different specifications, but also ensures the safety and stability of equipment operation.

[0020] In the preferred embodiment of this technical solution, please refer to Figure 4 As shown, the crushing component 3 includes a motor 301, which is located on one side of the upper crushing box 101. The drive end of the motor 301 is connected to a transmission shaft 302, which extends through the upper crushing box 101 to the inner wall of the upper crushing box 101. One end of the transmission shaft 302 is rotatably connected to a small gear 303. A large gear 304 is rotatably connected to one side of the small gear 303 near the center of the upper crushing box 101. The large gear 304 and the small gear 303 mesh with each other. A main shaft 305 is rotatably connected inside the large gear 304. A moving cone 306 is rotatably connected to the outside of the main shaft 305 near the upper end of the small gear 303. A balance ring 307 is rotatably connected to the lower end of the moving cone 306 near the upper end of the small gear 303. Fixed cones 308 are fixedly installed on both sides of the moving cone 306 near the movable housing 102 with external thread groove. The moving cone 306 and the movable housing 102 with external thread groove are integral structures. Furthermore, after the motor 301 starts, its drive end drives the transmission shaft 302 to rotate. The transmission shaft 302 extends through the upper crushing box 101 into the interior, thereby driving the small gear 303 at one end to rotate. Since the small gear 303 meshes with the large gear 304, it will drive the large gear 304 to rotate accordingly. The main shaft 305 inside the large gear 304 also rotates synchronously. The main shaft 305 then drives the moving cone 306 to rotate. The balance ring 307 at the lower end of the moving cone 306 rotates accordingly to maintain balance. The fixed cone 308 on both sides of the moving cone 306 is integrally connected to the movable housing 102 with the external thread groove and is fixed in position. When the moving cone 306 rotates, it cooperates with the fixed cone 308. Therefore, under the squeezing action of the moving cone 306, the material is crushed together, and the incoming material is squeezed, ground and crushed.

[0021] In the preferred embodiment of this technical solution, please refer to Figure 9 As shown, the crushing assembly 4 includes a drive gear 401, which is rotatably connected to the lower end of the main shaft 305 near the upper end of the inner wall of the lower crushing box 106. Driven gears 402 are rotatably connected to both sides of the drive gear 401, and the driven gears 402 mesh with the drive gear 401. A support plate 403 is fixedly connected to the lower end of the drive gear 401 and the driven gear 402. A receiving box 404 is rotatably connected to the lower end of the support plate 403 near the inner wall of the lower crushing box 106. The upper end of the receiving box 404 is funnel-shaped. Crushing rollers 405 are rotatably connected to the lower end of the drive gear 401 and the driven gear 402. Three sets of crushing rollers 405 are provided. Furthermore, when the main shaft 305 of the crushing assembly 3 rotates, it synchronously drives the lower drive gear 401 to rotate. The drive gear 401 drives the driven gears 402 on both sides to rotate in opposite directions through meshing, thereby driving the three sets of crushing rollers 405 to rotate in coordination. The initially crushed material discharged from the crushing assembly 3 falls into the receiving box 404 by gravity. At this time, the support plate 403, which is fixed to the lower end of the drive gear 401 and the driven gear 402, is sleeved on the outside of the connecting shaft of the three sets of crushing rollers 405 and rotates synchronously with the gears, synchronously driving the receiving box 404 connected at the lower end to crush the material. The material rotates inside the box 106, causing it to spread evenly within the receiving box 404. It is then guided through the funnel structure to the gap between the three sets of crushing rollers 405. Once in the crushing zone, the material is sheared by the teeth of the counter-rotating rollers, effectively separating entangled fibrous debris. Simultaneously, the squeezing and crushing action between the rollers further breaks down lumpy materials, resulting in finer, more uniform particles. The three sets of crushing rollers 405 work together to expand the crushing area, increasing the throughput per unit time. Furthermore, the combined shearing and crushing action ensures a more uniform crushing effect, laying a solid foundation for subsequent screening.

[0022] In the preferred embodiment of this technical solution, please refer to Figure 9 , Figure 10 , Figure 11 As shown, the screening assembly 5 includes a fixing ring 501, which is fixedly installed at the lower end of the receiving box 404. A ratchet 502 is rotatably connected to the lower end of the fixing ring 501 near the upper end of the inner wall of the discharge hopper 107. A screen 503 is fixedly installed on the inner wall of the ratchet 502. A connecting rod 504 is fixedly connected to the lower end of one side of the ratchet 502 near the outer diameter of the receiving box 404. A traction rod 505 is fixedly connected to the center of the inner side of the connecting rod 504. The teeth of the traction rod 505 correspond to those of the ratchet 502. A sleeve plate 506 is rotatably connected to the lower end of 504. A rotating shaft 507 is rotatably connected inside the front end of the sleeve plate 506. A second driving gear 508 is rotatably connected to the upper end of the rotating shaft 507. A second driven gear 509 is rotatably connected to both sides of the second driving gear 508. The second driving gear 508 and the second driven gear 509 mesh with each other. A grinding ring 5010 is rotatably connected to the upper end of the second driving gear 508 and the second driven gear 509. There are three sets of grinding rings 5010, and all three sets of grinding rings 5010 are in contact with the screen 503. Furthermore, the fixing ring 501 is fixed to the lower end of the receiving box 404, providing stable rotational support for the ratchet 502. When the receiving box 404 rotates, the connecting rod 504 fixed at the lower end of its outer diameter rotates synchronously, driving the inner traction rod 505 to push the ratchet 502 to rotate in one direction. This causes the screen 503 fixed on the inner wall to rotate synchronously with the ratchet 502. The material output from the crushing component 4 falls into the rotating screen 503 and is evenly dispersed under centrifugal force. Particles smaller than the screen holes pass directly through the screen 503 and are discharged through the discharge hopper 107 as qualified products. Particles larger than the screen holes remain on the surface of the screen 503. At the same time, the sleeve 506 at the lower end of the connecting rod 504 is sleeved on the outer wall of the rotating shaft 507 and rotates synchronously with the connecting rod 504. When rotating, the rotating shaft 507 rotates synchronously, and the rotating shaft 507 drives the second drive gear 508 to rotate. Through meshing with the second driven gears 509 on both sides, it drives the three sets of grinding rings 5010 to work together. Since the grinding rings 5010 are in close contact with the surface of the screen 503, during the rotation, they can grind the large particles on the surface of the screen 503 and refine them to a particle size that can pass through the screen holes. They can also scrape off the particles stuck in the screen holes to prevent blockage and ensure smooth screening. Therefore, the cooperation between the three sets of grinding rings 5010 and the rotating screen 503 greatly expands the grinding and screening area. While increasing the throughput per unit time, it ensures the uniformity and pass rate of the output material particle size, forming an efficient screening, grinding and unblocking closed loop.
