Description

Technical Field

[0001] This invention relates to the field of construction waste recycling technology, and more specifically, to an integrated construction waste recycling device. Background Technology

[0002] Construction waste typically contains a variety of complex components such as concrete blocks, bricks, steel bars, wood chips, plastic film, and soil. If it is directly dumped or landfilled without treatment, it not only occupies a large amount of land resources but also causes serious environmental pollution. Therefore, crushing, screening, and recycling construction waste has become an important development direction in the field of construction solid waste treatment.

[0003] Currently, construction waste processing often utilizes integrated recycling units. These units typically integrate the feeding, crushing, screening, conveying, and sorting mechanisms onto a single frame or mobile chassis, achieving one-stop crushing and screening of construction waste through continuous operation. However, construction waste generates a large amount of dust during crushing and screening. To suppress dust dispersion, existing technologies usually employ spray devices at the crushing chamber and / or feed inlet to spray water onto the construction waste and reduce dust generation. Furthermore, the moisture content of the material increases significantly during rainy weather or when processing construction waste with a high inherent moisture content.

[0004] However, construction waste is characterized by its high mud content and complex composition. When the moisture content of the material increases, fine particles such as mud and cement powder mix with water to form highly viscous wet materials. These wet materials easily adhere to the screen surface and clog the screen holes during screening, causing the screen to become stuck. Once the screen is stuck, fine particles cannot pass through normally, the material layer on the screen thickens rapidly, screening efficiency drops sharply, and the screening function may even be completely lost, seriously affecting the continuous and stable operation of the integrated recycling device.

[0005] In existing technologies, although some vibrating screens are equipped with self-cleaning devices (such as bouncing balls or vibrating balls at the bottom of the screen), these self-cleaning devices can only play a certain role in cleaning blockages at the bottom of the screen or inside the screen holes. When wet and sticky materials form a continuous mud cake layer or a stuck layer on top of the screen, the bottom self-cleaning device cannot reach the stuck area at the top because the top of the screen is always covered by the material to be screened, making it difficult to effectively solve the problem of stuck material at the top.

[0006] Based on the above background, the inventors have designed an integrated construction waste recycling device to solve at least one of the above problems, and hereby submit this application. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention discloses an integrated construction waste recycling device. By designing the screening plate as a structure that can be flipped around the support rod, when the top surface of the screening plate is stuck due to wet and sticky material, the support rod can be released through the locking component, allowing the screening plate to flip. After flipping, the top surface of the screening plate, which was originally facing upwards, can be turned downwards. At this time, the flushing component is activated to perform high-pressure spray flushing on the flipped screening plate, which can thoroughly wash away the wet and sticky material and mud cake layer adhering to the top surface of the screening plate. This effectively solves the technical problem of difficulty in cleaning the top of the screen after it is stuck due to material in the prior art, avoids the disadvantage of having to stop the machine for manual handling due to the top being stuck, and significantly improves the operating efficiency of the equipment.

[0019] 2. The present invention provides an integrated construction waste recycling device, which includes a vertical trough, a lifting plate, a first spring sheet, and a cylindrical lifting block on a movable base. A guide assembly consisting of a first horizontal trough, a second horizontal trough, and an inclined trough is correspondingly installed above the first mounting trough. When the movable base moves the flushing assembly to the area to be cleaned on the screening plate, the lifting block is located in the first horizontal trough. Under the downward pressure of the first spring sheet, the lifting block remains in a low position. At this time, the lower end of the scraper and the upper end of the movable plate are in contact, and the scraper can effectively scrape off the material. When cleaning is completed and the movable base continues to move to the inclined trough position of the guide assembly, the lifting block climbs along the inclined trough and enters the second horizontal trough. The lifting plate slides upward in the vertical trough and compresses the first spring sheet. The support plate connected to the lifting plate moves upward synchronously, thereby driving the scraper to rise, causing the lower end of the scraper and the upper end of the movable plate to move away from each other. This design effectively avoids contact friction between the scraper and the movable plate when the screening plate is reciprocating vibrating and screening or when the movable plate slides back and forth. This protects the surface structure of the scraper and the movable plate, reduces movement resistance, and extends the service life of the components.

[0020] 3. The integrated construction waste recycling device of the present invention uses a meshing locking structure composed of a long plate, a push block, a toothed plate and a locking gear, and an elastic locking structure composed of a lifting plate, a locking plate and a second spring plate. Under normal working conditions, the locking plate can stably lock the locking gear under the lifting of the lifting plate and the lifting block, thus preventing the support sleeve and the screening plate from rotating unexpectedly. When it is necessary to flip the screening plate, the moving seat drives the fixed plate to move, and the contact between the long plate and the inner wall of the first mounting groove pushes the push block to press down the toothed plate, so that the toothed plate and the locking gear are tightly meshed. This drives the toothed plate to drive the locking gear to rotate normally. After rotation, the flipping function of the screening plate is realized. This design ensures the structural stability of the screening plate under working conditions and the precise controllability during the flipping process.

[0021] 4. The integrated construction waste recycling device of the present invention includes a movable plate that can slide back and forth along the inner side of the base plate, and a reciprocating drive mechanism consisting of a half gear, a rack, a first sliding plate, and a first spring in the transmission chamber. This allows the movable plate to drive the screening plate to perform reciprocating vibration screening. During the screening process, the reciprocating motion causes the material to slide and be thrown relative to the surface of the screening plate, reducing the static residence time of wet and sticky materials on the top surface of the screening plate. This reduces the probability of screen hole blockage and top clogging, and plays a preventive role in preventing blockage. Attached Figure Description

[0046] Example 1

[0047] Please see Figures 1 to 17 As shown: This embodiment provides an integrated construction waste recycling device, mainly including a device body 1. The device body 1 has a crushing chamber 11 and a screening chamber 12 connected from top to bottom. A feed inlet 13 connects the upper end of the device body 1 to the crushing chamber 11, through which the construction waste to be processed enters the crushing chamber 11. The crushing chamber 11 is equipped with a crushing mechanism 2 for crushing the construction waste. The crushed material falls into the screening chamber 12 below under gravity for screening.

[0048] The left side of the screening chamber 12 is equipped with at least two screening components 3 from top to bottom. Each screening component 3 has a different screen aperture, which enables the grading and screening of construction waste of different particle sizes. Each screening component 3 includes two side plates 31, which are spaced apart along the length of the front and rear ends of the screening chamber 12. A base plate 32 is fixedly installed on both sides of the bottom of the two side plates 31 along the width direction. The base plate 32 enables the two side plates 31 to form a stable support structure. Furthermore, when the screened construction waste is scraped out, the base plate 32 can support the waste material. A movable plate 33 is slidably installed on the inner side of the base plate 32 along the width direction. The width of the movable plate 33 is greater than the sum of the widths of the two side plates 31, which allows the movable plate 33 to slide back and forth in the inner area of ​​the base plate 32.

[0049] Multiple slots 331 are spaced apart along the length of the upper and lower ends of the movable plate 33, and a screening plate 332 is installed in each slot 331. A support rod 333 is installed along the width direction at the center of the front and rear ends of the screening plate 332. One end of the support rod 333 is rotatably connected to the inner wall of the slot 331, so that the screening plate 332 can be rotated around the support rod 333. Under normal working conditions, the screening plate 332 is horizontally arranged, and its top surface receives the material falling from the crushing chamber 11. Fine particles fall through the screen holes on the screening plate 332, while coarse particles remain on the top surface of the screening plate 332.

[0050] Specifically, such as Figures 4 to 8 As shown, a rinsing assembly 34 is slidably disposed between the two side plates 31 along the length direction. The rinsing assembly 34 is used to clean the screening plate 332. The rinsing assembly 34 includes two support plates 342 and two movable seats 341.

The lifting plate 351 is also fixedly connected to the outer side of the corresponding support plate 342. This design allows the support plate 342 to slide up and down under the action of the lifting plate 351. A first spring piece 353 is also provided between the upper end of the interior of the vertical groove 35 and the lifting plate 351 to apply downward pressure to the lifting plate 351, so that the lifting plate 351 is kept in a low position under normal conditions. The lifting plate 351 is also provided with a cylindrical lifting block 352 at the end away from the support plate 342. The lifting block 352 is used to cooperate with the subsequent guide assembly 46, so as to control the support plate 342 and the scraper 343 to move up and down.

[0051] Specifically, a scraper 343 and a water storage box 344 are provided between the two side plates 31 along the width direction. The ends of the scraper 343 and the water storage box 344 are fixedly connected to the two support plates 342 respectively. The lower end of the scraper 343 is in contact with the upper end of the movable plate 33. When the rinsing assembly 34 moves along the length direction, the scraper 343 can scrape and push the residual material accumulated on the surface of the movable plate 33 and the screening plate 332. The water storage box 344 contains cleaning water. Multiple second nozzles 345 are evenly arranged along the width direction at the lower end of the water storage box 344. The multiple second nozzles 345 are connected to the interior of the water storage box 344. At least two second water guide pipes 346 are also connected between the upper end of the water storage box 344 and the interior. The second water guide pipes 346 are connected to an external water pump for continuously supplying water to the water storage box 344. When the support plate 342 moves the water storage box 344 left and right, the screening plate 332 can be rinsed.

[0052] like Figure 6 , Figure 7 , Figure 9 and Figure 14 As shown, the screening chamber 12 is also equipped with multiple locking components 4, with one locking component 4 corresponding to one screening component 3. One end of the support rod 333 is connected to the locking component 4, which is used to lock the rotating support rod 333. After locking, the screening plate 332 can maintain a stable horizontal working state. The rear inner wall of the screening chamber 12 is also equipped with the same number of moving components 5 as the screening components 3, with one moving component 5 corresponding to one screening component 3. The moving mechanism includes a second mounting groove 51, which is opened along the length direction on the rear inner wall of the screening chamber 12. A lead screw 52 is rotatably mounted in the second mounting groove 51, and a threaded block 53 is threaded onto the lead screw 52. The end of the threaded block 53 is fixedly connected to a moving seat 341. One end of the lead screw 52 extends to the outside of the equipment body 1, and a second motor 54 connected to the lead screw 52 is also provided on the right side of the outer wall of the equipment body 1. In use, the second motor 54 can be started to drive the lead screw 52 to rotate. After the lead screw 52 rotates, it can drive the moving seat 341 and the entire flushing assembly 34 to move along the length direction through the threaded block 53, thus realizing the scraping and flushing of garbage at the movable plate 33 and the screening plate 332.

[0053] Specifically, such as Figure 6 and Figure 8As shown, a long strip-shaped docking groove 48 is also provided on the front side of the inner wall of the screening chamber 12. The docking groove 48 is opened along the length direction on the front side of the inner wall of the screening chamber 12, and the docking groove 48 is arranged opposite to the second mounting groove 51. A docking rod 481 is fixedly installed in the docking groove 48 along the length direction, and a docking slider 482 is installed through the docking rod 481. The end of the docking slider 482 is connected to another movable seat 341. In this way, the cooperation between the docking rod 481 and the docking slider 482 makes the rinsing assembly 34 stable during movement, thereby avoiding the situation of deflection during sliding.

[0054] Example 2

[0055] Please see Figure 6 , Figure 7 and Figure 12 As shown, this embodiment further refines the structure of the locking component 4 based on Embodiment 1.

[0056] The locking assembly 4 includes a first mounting groove 41, which is formed along the length of the inner wall of the crushing chamber 11 on the front and rear sides. Multiple cylindrical support sleeves 42 are rotatably arranged within the first mounting groove 41. One end of each support rod 333 protrudes from the outer side of the movable plate 33. Each support rod 333 is positioned opposite to each support sleeve 42, and the protruding end of each support rod 333 is slidably connected to the inner wall surface of the corresponding support sleeve 42. Simultaneously, a locking gear 423 is provided on the outer side of the support sleeve 42. Longitudinal grooves 421 are formed along the width of both sides of the inner wall of the support sleeve 42. Longitudinal blocks 422 are slidably arranged within the longitudinal grooves 421, and the ends of the longitudinal blocks 422 are fixedly connected to the corresponding support rods 333. When the movable plate 33 slides back and forth, it simultaneously drives the support rods 333 and the longitudinal blocks 422 to slide within the support sleeves 42, thus avoiding interference with the back-and-forth sliding process of the support rods 333. Secondly, due to the cooperation between the longitudinal block 422 and the longitudinal groove 421, when the support sleeve 42 is driven to rotate, the support rod 333 and the screening plate 332 can be rotated synchronously through the longitudinal block 422, thus realizing the rotation function of the support rod 333.

[0057] Specifically, such as Figure 11 As shown, the lower end of the movable seat 341 is spaced apart from the support sleeve 42 and the support rod 333. This design ensures that the movable seat 341 will not interfere with the support sleeve 42 and the support rod 333 during movement.

[0058] like Figure 7 , Figure 11 and Figure 13As shown, a fixing plate 36 is provided along the length direction at one end of the movable base 341 facing the first mounting groove 41. The fixing plate 36 extends into the first mounting groove 41. A rectangular cavity is provided between the bottom surface and the interior of the fixing plate 36. A toothed plate 361 is slidably disposed in the cavity along the height direction. The lower end of the toothed plate 361 has teeth that mesh with the locking gear 423. The upper end of the toothed plate 361 has at least two notches 362, and the right side of the inner wall of each notch 362 has an inclined surface. A long groove 363 is provided along the length direction at the upper end of the cavity. The long groove 363 is connected to the left and right sides of the fixing plate 36. A long plate 364 is slidably disposed in the long groove 363. One end of the long plate 364 extends toward the left side of the fixing plate 36, and the length of the long plate 364 is greater than the length of the long groove 363. The lower end of the long plate 364 is also provided with at least two push blocks 365, each push block 365 extending into the corresponding notch 362, and the lower end of the push rod is U-shaped.

[0059] This design allows the fixed plate 36 to move with the movable seat 341 and cause the long plate 364 to contact the left side of the inner wall of the first mounting groove 41. The left side of the inner wall of the first mounting groove 41 pushes the left side of the long plate 364 into the long groove 363, while the right side of the long plate 364 protrudes from the right side of the fixed plate 36. During this process, the push block 365 at the lower end of the long plate 364 slides along the inclined surface of the right side of the inner wall of the notch 362 and presses down on the upper end of the toothed plate 361. This allows the push block 365 to apply downward pressure to the toothed plate 361, which keeps the toothed plate 361 in a stable, limited position. When the toothed plate 361 in this limited position contacts the locking gear 423, it can engage tightly with it, allowing the toothed plate 361 in this state to drive the locking gear 423 to rotate; similarly... When the fixed plate 36 drives the long plate 364 to contact the right side of the inner wall of the first mounting groove 41, the right side of the inner wall of the first mounting groove 41 pushes the right side of the long plate 364 into the long groove 363, while the left side of the long plate 364 will protrude from the left side of the fixed plate 36. At this time, the push block 365 moves from the upper surface of the toothed plate 361 to the inside position of the notch 362. After losing the downward pressure of the push block 365, the toothed plate 361 has room to move upward, so that the toothed plate 361 is in a relaxed state. When the toothed plate 361 in the relaxed state contacts the locking gear 423 (that is, when the moving seat 341 drives the toothed plate 361 to slide to the left), the toothed plate 361 cannot drive the locking gear 423 to rotate in contact with it. This allows the screening plate 332 to maintain a relatively stable horizontal state, and in this horizontal state, it can adapt to the operation of the scraper 343 and the second nozzle 345.

[0060] Specifically, such as Figure 12As shown, a second transmission component 43 is also provided between the multiple support sleeves 42. The second transmission component 43 includes multiple first transmission wheels 271, with one first transmission wheel 271 correspondingly mounted on one support sleeve 42. A first transmission belt 272 is adapted to connect the multiple first transmission wheels 271. When one of the support sleeves 42 is driven to rotate, the other support sleeves 42 can be driven to rotate synchronously through the first transmission belt 272, thereby realizing the synchronous flipping of multiple screening plates 332.

[0061] like Figure 7 and Figure 10 As shown, the locking assembly 4 also includes a bottom groove 44, which is connected to the middle of the inner bottom surface of the first mounting groove 41. A rectangular locking plate 441 is slidably disposed on the upper inner end of the bottom groove 44 along the height direction. The top of the locking plate 441 has a toothed groove 442 that can mesh with the locking gear 423. A second spring piece 443 is also disposed between the inner bottom surface of the bottom groove 44 and the locking plate 441, which is used to apply an upward elastic force to the locking plate 441. A first lifting groove 45 is also connected to the right side of the inner surface of the first mounting groove 41 along the length direction. The left side of the inner surface of the first lifting groove 45 is connected to the bottom groove 44. A lifting plate 451 is slidably disposed in the first lifting groove 45, and a first mounting block 452 is also disposed between the adjacent ends of the lifting plate 451 and the locking plate 441. When the lifting plate 451 moves upward, the locking plate 441 can be moved upward by the first mounting block 452. This allows the toothed groove 442 on the top of the locking plate 441 to engage with the locking gear 423, preventing the locking gear 423 and the support sleeve 42 from rotating. Therefore, when the lifting plate 451 is not raised, the second spring 443 can retract the locking plate 441 and the lifting plate 451. After retraction, the locking plate 441 and the locking gear 423 maintain a relaxed engagement. In this state, the locking plate 441 can still apply a certain clamping force to the locking gear 423, ensuring that the locking gear 423 and the support sleeve 42 do not rotate due to friction when the toothed plate 361 and the locking gear 423 are in contact. Therefore, by utilizing the clamping force of the locking plate 441, premature overturning of the scraper 343 and the second nozzle 345 during construction waste processing can be prevented.

[0062] like Figure 6 , Figure 7 and Figure 10As shown, a guide assembly 46 is also provided above the first mounting groove 41. The guide assembly 46 includes a first horizontal groove 461, a second horizontal groove 463, and an inclined groove 462. The first horizontal groove 461 and the second horizontal groove 463 are respectively spaced apart along the length direction on the left side and the right side of the inner wall of the screening chamber 12, and the second horizontal groove 463 is higher than the first horizontal groove 461. The inclined groove 462 is disposed between the first horizontal groove 461 and the second horizontal groove 463, and the inclined groove 462 is also interconnected with the first horizontal groove 461 and the second horizontal groove 463. The internal heights of the first horizontal groove 461, the second horizontal groove 463 and the inclined groove 462 are the same. The lifting block 352 is opposite to the first horizontal groove 461, and one end of the lifting block 352 is adapted to extend into the first horizontal groove 461. This design allows the lifting block 352 to slide in the first horizontal groove 461, the second horizontal groove 463 and the inclined groove 462 respectively when the moving seat 341 drives the lifting plate 351 to move left and right.

[0063] A rectangular second lifting groove 47 is connected to the upper part of the inner wall of the second horizontal groove 463, and the rear end of the second lifting groove 47 is connected to the first lifting groove 45. A long strip-shaped lifting block 471 is slidably arranged along the height direction at the end of the second lifting groove 47 facing the second horizontal groove 463, and an inclined surface is formed at the end of the lifting block 471 facing the inclined groove 462. The upper end of the lifting plate 451 extends into the second lifting groove 47, and a second mounting block 472 is arranged along the width direction between the back of the lifting block 471 and the lifting plate 451.

[0064] In the above structure, when the lifting block 471 moves upward, it can simultaneously drive the second mounting block 472 and the lifting plate 451 to slide upward. On the other hand, when the flushing assembly 34 moves left and right, its moving seat 341 will drive the lifting block 352 to move to the position of the first horizontal groove 461. When the lifting block 352 is in a low position, under the downward pressure of the first spring plate 353, the support plate 342 and scraper 343 connected to the lifting plate 351 are in a low position. At this time, the lower end of the scraper 343 is in contact with the upper end of the movable plate 33. The scraper 343 can effectively scrape off the residual material accumulated on the surface of the movable plate 33 and the screening plate 332 during the movement. After cleaning is completed, the movable seat 341 will drive the lifting plate 351 to reset and slide. At this time, the lifting block 352 will move from the first horizontal groove 461 to the inclined groove 462. Since the inclined groove 462 is inclined, as the lifting block 352 climbs along the inclined groove 462, it is squeezed upward by the groove wall of the inclined groove 462. This will drive the lifting plate 351 to slide upward in the vertical groove 35 and compress the first spring piece 353. At this time, the support plate 342 connected to the lifting plate 351 will move upward synchronously, thereby driving the scraper 343 to rise. When the lifting block 352 climbs to the second horizontal groove 463, the lower end of the scraper 343 and the upper end of the movable plate 33 move away from each other, forming a gap between them. The purpose of this design is that when the movable plate 33 slides back and forth, since the scraper 343 is completely separated from the movable plate 33, friction between the scraper 343 and the movable plate 33 can be effectively avoided. When the friction is reduced, the sliding speed of the movable plate 33 can be ensured, thus guaranteeing its screening quality, while also reducing the friction between the scraper 343 and the movable plate 33.

[0065] It should be noted that the number of locking gears 423 can be flexibly configured according to actual working conditions. Specifically, locking gears 423 can be set on the outer side of only one support sleeve 42, or they can be set on the outer side of each support sleeve 42. When locking gears 423 are set on only one support sleeve 42, the length of locking plate 441 and bottom groove 44 only needs to be adapted to the single locking gear 423. At this time, locking plate 441 forms a single-point lock on the support sleeve 42, and the other support sleeves 42 are kept synchronous with the locked support sleeve 42 through the first transmission belt 272. When locking gears 423 are set on the outer side of each support sleeve 42, the length of locking plate 441 and bottom groove 44 should be extended accordingly to form meshing lock with all locking gears 423 at the same time. Increasing the length of locking plate 441 can significantly improve the overall locking stability of screening plate 332, which is particularly suitable for handling construction waste with large weight, strong impact force, or complex composition. Those skilled in the art can reasonably select the number of locking gears 423 and the appropriate length of locking plate 441 and bottom groove 44 based on the type, weight distribution of construction waste and the size specifications of screening plate 332.

[0066] Example 3

[0067] Please see Figure 1 , Figures 15 to 17 As shown, this embodiment, based on embodiment one, further includes a transmission mechanism for driving the movable plate 33 to slide back and forth, and a specific structure for the crushing mechanism 2.

[0068] A transmission chamber 6 is also provided on the front side of the screening chamber 12 along the inside of the equipment body 1, and the transmission chamber 6 is separated from the screening chamber 12. At least two extension rods 334 are fixedly provided at both the front and rear ends of the movable plate 33 along the width direction, and both extension rods 334 are slidably connected to the inner wall surface of the screening chamber 12. The front end of the extension rod 334 facing the screening chamber 12 also extends into the transmission chamber 6, and a connecting plate 335 is slidably provided in the transmission chamber 6 along the width direction. The protruding end of the extension rod 334 is fixedly connected to the connecting plate 335.

[0069] A first sliding groove 61 is formed along the width direction on the inner bottom surface of the transmission chamber 6. A first sliding plate 62 is slidably disposed at the front end of the first sliding groove 61, and the upper rear side of the first sliding plate 62 is fixedly connected to the connecting plate 335. A first spring 63 is also provided between the rear end of the first sliding groove 61 and the first sliding plate 62, and the first spring 63 is used to apply a forward elastic force to the first sliding plate 62. A second sliding groove 64 is formed along the width direction on the front side of the upper end of the first sliding plate 62. A rack 641 is slidably disposed at the rear end of the second sliding groove 64, and a second spring 642 is also provided between the front end of the second sliding groove 64 and the rack 641, and the second spring 642 is used to apply a backward elastic force to the rack 641. A drive rod 65 is also provided above the rack 641 along the length direction, and the drive rod 65 is rotatably connected to both sides of the inner wall of the transmission chamber 6. A half gear 651 is also provided in the middle of the outer wall of the drive rod 65, and the half gear 651 is meshed with the rack 641. The purpose of this design is that when the drive rod 65 drives the half gear 651 to rotate clockwise, it is just right to match the crushing operation of the crushing mechanism 2. Then the rack 641 will slide forward and press the second spring 642. During this process, the power of the rack 641 cannot be transmitted to the first slide plate 62, so the first slide plate 62 cannot move in the first slide groove 61. When it is necessary to remove the waste from the screening plate 332, the crushing mechanism 2 drives the drive rod 65 to rotate counterclockwise. At this time, the power of the rack 641 can be transmitted to the first slide plate 62, and the first slide plate 62 can push the connecting plate 335 and the extension plate to move. This can realize the reciprocating motion of the movable plate 33, and thus allow the screening plate 332 to perform reciprocating screening.

[0070] The crushing mechanism 2 includes a drive shaft 21 and a driven shaft 22. The drive shaft 21 and the driven shaft 22 are respectively arranged at the front and rear ends inside the crushing chamber 11 along the length direction, and one end of each drive shaft 21 and driven shaft 22 extends out from the right side of the equipment body 1. Each end of the drive shaft 21 and driven shaft 22 facing the crushing chamber 11 is provided with a matching crushing roller 23, and the exit ends of both the drive shaft 21 and driven shaft 22 are provided with meshing transmission gears 25. A first motor 24 is also provided on the right side of the equipment body 1, and the transmission shaft of the first motor 24 is connected to the drive shaft 21. In use, starting the first motor 24 drives the drive shaft 21 to rotate. The drive shaft 21 drives the driven shaft 22 and the two crushing rollers 23 to rotate relative to each other through the meshing transmission gears 25, thereby crushing the construction waste. One end of the drive rod 65 extends to the right side of the equipment body 1, and a first transmission component 27 is provided between the end of the drive rod 65 and the end of the drive shaft 21. The first transmission component 27 includes two first transmission wheels 271. Both the end of the drive rod 65 and the end of the drive shaft 21 are provided with first transmission wheels 271, and a first transmission belt 272 is adapted between the two first transmission wheels 271.

[0071] In the above structure, when the first motor 24 drives the drive shaft 21 to rotate, the drive shaft 21 synchronously drives the drive rod 65 to rotate via the first transmission belt 272. The half gear 651 on the drive rod 65 rotates with the drive rod 65. When the teeth of the half gear 651 mesh with the rack 641, the half gear 651 pushes the rack 641 forward. The rack 641 drives the first slide plate 62 and the connecting plate 335 to slide forward via the second slide groove 64, and then drives the movable plate 33 and the screening plate 332 to move forward via the extension rod 334. When the teeth of the half gear 651 disengage from the rack 641, the rack 641 returns to its original position under the elastic force of the second spring 642. At the same time, the first slide plate 62 slides backward under the elastic force of the first spring 63, driving the movable plate 33 and the screening plate 332 to move backward. As the drive rod 65 continues to rotate, the half gear 651 and the rack 641 intermittently mesh, thereby realizing the reciprocating vibration of the movable plate 33 and the screening plate 332.

[0072] Specifically, multiple lateral discharge ports 7 are provided between the left side of the equipment body 1 and the inner wall of the screening chamber 12, with each lateral discharge port 7 opposite to a screening component 3. The inner bottom surface of the lateral discharge port 7 is flush with the upper surface of the bottom plate 32 to facilitate the smooth discharge of the screened material. Simultaneously, rectangular channels 71 are provided along the width direction on both sides of the inner wall of the lateral discharge port 7. A baffle 72 is slidably installed at one end of the channel 71 near the lateral discharge port 7, and an electric telescopic rod 73 is provided at the end of the channel 71 away from the lateral discharge port 7, which can drive the baffle 72 to slide. In use, the electric telescopic rod 73 can drive the baffle 72 to slide within the channel 71, thus opening or closing the lateral discharge port 7 and controlling the discharge of the screened material.

[0073] Specifically, a dust suppression component 26 is provided at the upper part of the crushing chamber 11. The dust suppression component 26 includes a frame-shaped water spray pipe 261 filled with water. Multiple first nozzles 262 are arranged at intervals on the inner bottom surface of the water spray pipe 261, and all the first nozzles 262 are connected to the water spray pipe 261. A first water guide pipe 263 is also provided at the upper end of the water spray pipe 261, which is connected to an external water pump for supplying water to the water spray pipe 261. During the crushing process, the water pump is activated to supply water to the water spray pipe 261, and the water is sprayed downwards through the first nozzles 262, effectively suppressing the diffusion of dust within the crushing chamber 11.

[0074] Specifically, a discharge hopper 14 is provided between the bottom surface of the equipment body 1 and the screening chamber 12, and the fine particles that fall after screening are collected in the discharge hopper 14.

[0075] The working principle of this invention is as follows: When using this device, there are three switchable working states: normal crushing state, preventive reciprocating state, and blockage clearing state. The working principles of each state are as follows: Normal crushing stage: The construction waste to be processed is fed into the crushing chamber 11 through the feed inlet 13. The first motor 24 is started and rotated in the forward direction. The first motor 24 drives the driven shaft 22 and the two crushing rollers 23 to rotate relative to each other through the drive shaft 21 and the transmission gear 25, thus crushing the construction waste. The crushed material falls into the screening chamber 12 below under the action of gravity. At this time, the screening plate 332 is in a stationary horizontal state, and natural screening is carried out by the weight of the material and the impact of falling. At the same time, the water pump is started to supply water to the water spray pipe 261 of the dust suppression component 26, and the first nozzle 262 sprays downward to suppress the spread of dust in the crushing chamber 11.

[0076] In this state, the first motor 24 maintains positive unidirectional rotation. Although the half gear 651 on the drive rod 65 rotates synchronously with the drive shaft 21, its meshing relationship with the rack 641 does not trigger the effective reciprocating drive of the first slide plate 62. At this time, the movable plate 33 and the screening plate 332 remain stationary. The rinsing assembly 34 stays at the initial end of the screening plate 332 in the length direction. The lifting block 352 is located in the second horizontal groove 463. The lower end of the scraper 343 and the upper end of the movable plate 33 are far apart from each other to avoid interference with the stationary screening plate 332. Preventative Phase: When the construction waste being processed has a high moisture content and poses a risk of clogging, but the screening plate 332 is not yet completely blocked, the equipment can be switched to the preventative reciprocating state. At this time, feeding into the crushing chamber 11 is stopped, the first motor 24 is controlled to rotate in reverse, and the drive shaft 21 synchronously drives the drive rod 65 to rotate via the first transmission belt 272. The half gear 651 on the drive rod 65 and the rack 641 enter an effective meshing state. The half gear 651 pushes the rack 641 to move forward, and the rack 641 drives the first slide plate 62 and the connecting plate 335 to slide forward via the second slide groove 64, and then drives the movable plate 33 and the screening plate 332 to move forward via the extension rod 334. When the teeth of the half gear 651 disengage from the rack 641, the rack 641 returns to its original position under the elastic force of the second spring 642. At the same time, the first slide plate 62 slides backward under the elastic force of the first spring 63, driving the movable plate 33 and the screening plate 332 to move backward. As the drive rod 65 continues to rotate, the half gear 651 and the rack 641 intermittently mesh, thereby realizing the reciprocating motion of the movable plate 33 and the screening plate 332. Through this reciprocating motion, the material on the top surface of the screening plate 332 undergoes relative sliding and slight throwing, making it difficult for wet and sticky materials to accumulate statically at the screen holes, thus playing a role in preventing blockage. Clogging and Cleaning Stage: When the top surface of the screening plate 332 has become clogged due to wet and sticky materials, and the screening efficiency has significantly decreased, the first motor 24 is stopped (i.e., the reciprocating motion is stopped), bringing the movable plate 33 and the screening plate 332 to a standstill. The equipment is then switched to the clogging and cleaning state, and the second motor 54 is started to drive the lead screw 52 to rotate, causing the flushing assembly 34 to move from right to left along its length. Before moving, the flushing assembly 34 is at the initial end, the lifting block 352 is in the first horizontal groove 461 (or descends into the first horizontal groove 461 during the movement), and the lower end of the scraper 343 is in contact with the upper end of the movable plate 33. Simultaneously, the external water pump is started to supply water to the water storage box 344, and the second nozzle 345 sprays downwards synchronously. While the scraper 343 scrapes away residual materials from the surfaces of the movable plate 33 and the screening plate 332, the top surface of the screening plate 332 is hydraulically flushed. The wet and sticky materials are effectively cleaned through the combined action of mechanical scraping and hydraulic flushing. When the scraper 343 pushes the waste from the right side of the screening plate 332 to the left side, the baffle 72 at the side discharge port 7 is opened to collect and process the scraped construction waste.

[0077] At this time, the long plate 364 at the end of the fixed plate 36 contacts the left side of the inner wall of the first mounting groove 41, and the push block 365 presses down the toothed plate 361 to make the toothed plate 361 tightly mesh with the locking gear 423. Then the second motor 54 drives the moving seat 341 to move in the opposite direction from left to right. The tightly meshed toothed plate 361 drives the locking gear 423, the support sleeve 42 and the first transmission wheel 271 to rotate, and then drives all the support sleeves 42 to rotate synchronously through the first transmission belt 272, so as to realize the flipping of the screening plate 332, so that the original top surface of the screening plate 332 can be turned downward. After being flipped into position, the movable seat 341 continues to move to the right, and the lifting block 352 climbs along the inclined groove 462 to the second horizontal groove 463, driving the lifting plate 351, support plate 342, and scraper 343 to rise, so that the lower end of the scraper 343 and the upper end of the movable plate 33 move away from each other; at the same time, the lifting block 471 is lifted, and the lifting plate 451 drives the locking plate 441 to rise and engage with the locking gear 423 to lock it, ensuring that the flipped screening plate 332 remains stable. If the screening plate 332 is severely clogged, the above flipping and rinsing operation can be repeated one or more times as needed.
