Description

Technical Field

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

[0002] Construction waste refers to various types of waste generated during the demolition, construction, reconstruction, repair, decoration, and natural disasters of buildings and structures. It mainly includes waste concrete blocks, asphalt concrete blocks, bricks and tiles, etc. With rapid economic development, accelerated engineering construction, and the booming real estate industry, the production of construction waste is also growing rapidly. Unprocessed construction waste is piled up on land for a long time, occupying land. At the same time, various types of construction waste are mixed together, making it more inconvenient for workers to transport and unload, which not only wastes resources but also increases construction costs.

[0003] Chinese Patent Publication No. CN218656075U discloses a novel construction waste crushing device for building engineering. A motor drives a drum to rotate, causing a slider to slide within a reciprocating groove. A connecting rod reciprocates under the slider's influence, which in turn drives the connecting rod and an irregular gear to reciprocate under the action of a rotating shaft. Simultaneously, the irregular gear meshes with a rack, causing the rack to reciprocate. Then, a connecting plate drives a perforated plate to reciprocate inside a first-stage chamber, thereby achieving the screening and filtering of the crushed construction waste. This reduces the workload of workers, and the crushed and screened construction waste occupies less space, making transportation more convenient.

[0004] After crushing the construction waste, the crushing device in the aforementioned application mainly rotates the drum by starting the motor. At this time, the slider slides inside the reciprocating trough and drives the connecting rod to move. The connecting rod drives the connecting plate to move through the gear and rotating shaft. The connecting plate drives the screen plate to reciprocate, thereby performing screening. However, the screen plate in the aforementioned application does not have a buffer structure. Therefore, when the crushed stone falls on the top of the screen plate, the impact force generated is completely absorbed by the screen plate itself, thereby accelerating the deformation process of the screen plate and reducing its service life. Therefore, it has certain limitations. Summary of the Invention

One end of the water pump pipe passes through the top of the water tank and extends into the interior of the water tank. A support plate is fixedly connected to the outer wall of the water delivery pipe. The outer wall of the water tank is fixedly connected to the outer wall of the support plate. The presence of the support plate can provide support for the water delivery pipe. The outer wall of the atomizing head is fixedly connected to the end of the water pump pipe away from the water pump. Clean water can enter the interior of the atomizing head through the water pump pipe and be sprayed out through the atomizing head.

[0014] According to the above technical solution, the air extraction assembly includes an air pipe, a replaceable filter chamber, an air pump, and an input pipe.

The start switch of the air pump is connected to the signal of an external controller, and the air pump can be controlled by the external controller. The end of the input pipe away from the air pump is connected to the replaceable filter chamber. After the air pump is started, the air inside the replaceable filter chamber can be extracted through the input pipe.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention, by comprising an outer plate, springs, a movable block, a perforated plate, and a frame, generates an impact force when construction waste falls onto the top of the perforated plate through the crushing chamber. Since the perforated plate is connected to the movable block, and the inner wall of the movable block is slidably connected to the outer wall of the curved rod, the perforated plate will cause the movable block to slide against the outer wall of the curved rod under the impact force. Because the springs are installed at the top and bottom of the movable block, when the position of the movable block changes, the springs will deform under the action of the movable block and absorb the impact force, thus achieving a buffering effect. After the impact force is absorbed, the springs will push the movable block to reset, and the movable block will cause the perforated plate to reset. During the reset process of the perforated plate, the construction waste on top of the perforated plate will be filtered through the perforated plate. Simultaneously, the frame prevents construction waste from falling from the top of the perforated plate.

[0017] 2. This invention, by providing a card plate, a card slot, and a card rod, allows the card plate's outer wall to slide and connect with the card slot's inner wall, and the card plate's outer wall to be fixedly connected to the outer wall of the perforated plate. Therefore, the perforated plate can move the card plate, which is then slidably moved into the card slot. The card rod's tip penetrates the top of the movable block and extends below it, with its outer wall slidably connected to both the card plate's inner wall and the movable block's inner wall. Thus, the card rod can be installed by sliding, penetrating both the card plate and the movable block, thereby fixing the perforated plate. The operation is simple and convenient, and the perforated plate can be replaced by sliding, ensuring the perforated plate's screening effect.

[0018] 3. This invention, by comprising a water tank, a water pump, a water suction pipe, a water delivery pipe, and an atomizing head, allows for the screening of crushed construction waste. When the water pump is activated, one end of the water suction pipe extends into the water tank, drawing clean water from the tank through the suction pipe and delivering it to the atomizing head via the delivery pipe. Since the atomizing head is located at the top of a perforated plate, the water sprayed from it humidifies the air above the perforated plate, causing dust particles to absorb moisture and increase their weight, thus suppressing dust. Simultaneously, the outer wall of the delivery pipe is uniformly fitted with fixing plates to assist in securing the pipe and ensure its stability.

[0019] 4. This invention, by incorporating an air pipe, a replaceable filter chamber, and an air pump, activates the air pump when the crushing chamber is started and the building materials are being crushed. The air pump is connected to the replaceable filter chamber via an input pipe, and one end of the air pipe is connected to the replaceable filter chamber while the other end is connected to the interior of the crushing chamber. Therefore, when the air pump is started, air can be drawn out of the crushing chamber through the input pipe and the air pipe, and then transported to the interior of the replaceable filter chamber for filtration through the air pipe. The filtered air then enters the interior of the air pump through the input pipe and is discharged by the air pump, ensuring a safe working environment around the crushing chamber.

[0022] 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.

[0023] Please see Figure 1-6 The present invention provides a technical solution: a novel construction waste crushing device, comprising a crushing chamber 1, support legs 2 and a feeding hopper 3. The support legs 2 are fixedly connected to the bottom of the crushing chamber 1, and the feeding hopper 3 is fixedly connected to the top of the crushing chamber 1. A screening component 4 is installed on the outer wall of the support legs 2. The screening component 4 consists of a movable unit and a fixed unit. The movable unit is located on the outer wall of the support legs 2, and the fixed unit is located inside the movable unit. A dust suppression component 5 is installed on the outer wall of the crushing chamber 1, and an air extraction component 6 is installed on the outer wall of the crushing chamber 1.

[0024] The movable unit includes a bent rod 401, an outer plate 402, a spring 403, a movable block 404, a perforated plate 405, and a frame 406. The bent rod 401 is fixedly connected to the outer surface of the support leg 2, the outer plate 402 is fixedly connected to the outer surface of the bent rod 401, the spring 403 is fixedly connected to the outer wall of the outer plate 402, the movable block 404 is located outside the bent rod 401, one end of the bent rod 401 passes through the movable block 404 and extends to the outside of the movable block 404, and the inner wall of the movable block 404 is slidably connected to the outer wall of the bent rod 401. The movable block 404 can slide on the outer wall of the bent rod 401. The side of the spring 403 away from the outer plate 402 is fixedly connected to the outer wall of the movable block 404. The spring 403 can ensure the stability of the movable block 404. The hollow plate 405 is installed on the outer wall of the movable block 404. The outer wall of the hollow plate 405 contacts the outer wall of the movable block 404 and is slidably connected to the outer wall of the movable block 404. The hollow plate 405 can move on the outer wall of the movable block 404. The frame 406 is fixedly connected to the top of the hollow plate 405.

[0025] By incorporating an outer plate 402, springs 403, movable blocks 404, perforated plates 405, and a frame 406, when construction waste falls through the crushing chamber 1 onto the top of the perforated plate 405, it generates an impact force. Since the perforated plate 405 is connected to the movable block 404, and the inner wall of the movable block 404 is slidably connected to the outer wall of the bent rod 401, the perforated plate 405 will cause the movable block 404 to slide against the outer wall of the bent rod 401 under the impact force. Because the springs 403 are installed at the top and bottom of the movable block 404 respectively, when the movable block 404... When the position of the movable block 404 changes, the spring 403 will deform under the action of the movable block 404 and absorb the impact force, thus playing a buffering role. After the impact force is absorbed, the spring 403 will push the movable block 404 to reset. The movable block 404 will drive the perforated plate 405 to reset. During the reset process of the perforated plate 405, the construction waste on the top of the perforated plate 405 will be filtered through the perforated plate 405. At the same time, the frame 406 can prevent construction waste from falling from the top of the perforated plate 405.

[0026] The fixing unit includes a locking plate 407 and a locking rod 409. The locking plate 407 is fixedly connected to the outer wall of the hollow plate 405. The movable block 404 has a locking groove 408 inside. The outer wall of the locking plate 407 is slidably connected to the inner wall of the locking groove 408. The locking plate 407 can slide inside the locking groove 408. The locking rod 409 is installed on the top of the movable block 404. The bottom end of the locking rod 409 passes through the movable block 404 and the locking plate 407 and extends to the bottom of the movable block 404. The outer wall of the locking rod 409 is slidably connected to the inner wall of the sliding locking plate 407 inside the movable block 404. The locking rod 409 can slide inside the sliding locking plate 407 inside the movable block 404.

[0027] By configuring a card plate 407, a card slot 408, and a card rod 409, the outer wall of the card plate 407 is slidably connected to the inner wall of the card slot 408, and the outer wall of the card plate 407 is fixedly connected to the outer wall of the perforated plate 405. Therefore, the perforated plate 405 can move the card plate 407 and slide it into the inside of the card slot 408. Since the top of the card rod 409 penetrates the top of the movable block 404 and extends to the bottom of the movable block 404, and the outer wall of the card rod 409 is slidably connected to the inner wall of the card plate 407 and the inner wall of the movable block 404 respectively, the card rod 409 can be installed by sliding, so that the card rod 409 penetrates the card plate 407 and the movable block 404, thereby completing the fixation of the perforated plate 405. The operation is simple and convenient, and the perforated plate 405 can be replaced by sliding, thereby ensuring the screening effect of the perforated plate 405.

[0028] The dust suppression component 5 includes a water tank 501, a water pump 502, a water suction pipe 503, a water delivery pipe 504, and an atomizing head 505. The water tank 501 is fixedly connected to the outer wall of the crushing chamber 1. The water pump 502 is fixedly connected to the top of the water tank 501. The start switch of the water pump 502 is connected to an external controller signal, allowing control of the water pump 502 via the external controller. The water suction pipe 503 is fixedly connected to the outer wall of the water pump 502, with one end penetrating through the top of the water tank 501 and extending to the top of the water tank 501. Inside, the water supply pipe 504 is fixedly connected to the output end of the water pump 502. A support plate is fixedly connected to the outer wall of the water supply pipe 504. The outer wall of the water tank 501 is fixedly connected to the outer wall of the support plate. The support plate can support the water supply pipe 504. The atomizing head 505 is set outside the frame 406. The outer wall of the atomizing head 505 is fixedly connected to the end of the water pump 503 away from the water pump 502. Clean water can enter the interior of the atomizing head 505 through the water pump 503 and be sprayed out through the atomizing head 505.

[0029] The system includes a water tank 501, a water pump 502, a water extraction pipe 503, a water delivery pipe 504, and an atomizing head 505. When screening the crushed construction waste, the water pump 502 is activated. Since one end of the water extraction pipe 503 extends into the water tank 501, when the water pump 502 is activated, it draws clean water from the water tank 501 through the water extraction pipe 503 and delivers it to the atomizing head 505 through the water delivery pipe 504. Because the atomizing head 505 is located on top of the perforated plate 405, when clean water is sprayed out through the atomizing head 505, it can humidify the air on top of the perforated plate 405. This causes the dust in the air on top of the perforated plate 405 to absorb moisture, thereby increasing the weight of the dust and achieving a dust suppression effect. At the same time, fixing plates are evenly installed on the outer wall of the water delivery pipe 504 to help fix the water delivery pipe 504 and ensure its stability.

[0030] The air extraction assembly 6 includes an air pipe 601, a replaceable filter chamber 602, an air pump 603, and an input pipe 604. The air pipe 601 is fixedly connected to the top of the crushing chamber 1, and one end of the air pipe 601 is connected to the interior of the crushing chamber 1. The replaceable filter chamber 602 is fixedly connected to the outer wall of the crushing chamber 1, and the end of the air pipe 601 away from the crushing chamber 1 is connected to the replaceable filter chamber 602. The gas inside the crushing chamber 1 can enter the interior of the replaceable filter chamber 602 through the air pipe 601 and be filtered by the replaceable filter chamber 602. The air pump 603 is fixedly connected to the outer wall of the crushing chamber 1, and the start switch of the air pump 603 is connected to an external controller signal, so the air pump 603 can be controlled by the external controller. The input pipe 604 is fixedly connected to the input end of the air pump 603, and the end of the input pipe 604 away from the air pump 603 is connected to the replaceable filter chamber 602. After the air pump 603 is started, the air inside the replaceable filter chamber 602 can be extracted through the input pipe 604.

[0031] By incorporating an air pipe 601, a replaceable filter chamber 602, and an air pump 603, the air pump 603 is activated when the crushing chamber 1 is started and the building materials are crushed. The air pump 603 is connected to the replaceable filter chamber 602 via an input pipe 604. One end of the air pipe 601 is connected to the replaceable filter chamber 602, and the other end is connected to the interior of the crushing chamber 1. Therefore, when the air pump 603 is started, air can be extracted from the interior of the crushing chamber 1 through the input pipe 604 and the air pipe 601, and then transported to the interior of the replaceable filter chamber 602 for filtration through the air pipe 601. The filtered air then enters the interior of the air pump 603 through the input pipe 604 and is discharged through the air pump 603, ensuring the working environment around the crushing chamber 1.

[0032] Working Principle: During operation, the construction waste to be crushed is fed into the crushing chamber 1 through the feeding funnel 3, and the crushing chamber 1 is activated to crush the waste. The crushed waste falls onto the top of the perforated plate 405. Since the perforated plate 405 is engaged with the movable block 404 via the clamping plate 407, the crushed waste exerts pressure on the perforated plate 405 upon impact. This pressure causes the perforated plate 405 to lower the movable block 404 via the clamping plate 407. Because springs 403 are installed at both the top and bottom of the movable block 404, the impact force generated by the construction waste falling onto the top of the perforated plate 405 is absorbed by the springs 403. Once the impact force is dissipated, the springs 403 return to their original position and move the perforated plate 405 via the movable block 404. As the material rises, friction occurs between the construction waste pieces. Smaller pieces that meet the specifications fall through the perforated plate 405, while larger pieces are blocked by the perforated plate 405 and moved under its guidance, eventually accumulating in a suitable location. Simultaneously, during waste crushing, the air pump 603 is activated. The air pump 603 extracts air from the crushing chamber 1 through the input pipe 604 and the air pipe 601, filters it through the replaceable filter chamber 602, and discharges it through the output pipe. During construction waste screening, the water pump 502 is activated. Since one end of the water suction pipe 503 is connected to the inside of the water tank 501, after the water pump 502 is activated, clean water is extracted through the water suction pipe 503 and delivered to the inside of the atomizing head 505 through the water delivery pipe 504, and then sprayed out through the atomizing head 505 to humidify the area around the perforated plate 405.
