Description

Technical Field

[0001] This invention relates to the field of construction waste treatment technology, specifically to an environmentally friendly construction waste crushing device. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, a large amount of construction waste is generated during the demolition, reconstruction and renovation of buildings. If this waste is not handled properly, it will have a serious impact on the environment, such as pollution of air, soil and water sources, and even pose a threat to human health. Therefore, how to effectively deal with this construction waste has become an urgent problem to be solved. Traditional methods often involve landfilling or simple dumping, which not only wastes a lot of reusable resources, but also causes long-term pollution to the environment.

[0003] Chinese Patent (CN 210280152 U) discloses a construction waste crushing device, comprising a box base mounted on the ground, a motor connected to one side of the box base, a transmission gear connected to the other side of the box base, and a baffle plate disposed inside the box base; characterized in that: the box base above the baffle plate is provided with a pair of first front through holes, first rear through holes, second front through holes, and second rear through holes, and a transmission shaft is provided between the first front through hole and the first rear through hole, and between the second front through hole and the second rear through hole, and the transmission shaft is provided with a keyway, one end of one transmission shaft is connected to the motor, and the other end of the transmission shaft is connected to the other transmission shaft through the transmission gear, and a first roller and a second roller are respectively fitted on the outside of each transmission shaft, and the first roller and the second roller are circumferentially fixed to their respective transmission shafts.

[0004] While the aforementioned patent allows for quick replacement of damaged spherical crushing heads with new ones, saving maintenance time and reducing crushing costs, it cannot crush larger construction waste, making it unsuitable for crushing various sizes of construction waste. Furthermore, the large amount of dust generated during crushing and crushing cannot be centrally treated, which not only harms the health of workers but also pollutes the air.

[0005] Therefore, the present invention provides an environmentally friendly construction waste crushing device to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides an environmentally friendly construction waste crushing device to solve the problem of being able to crush construction waste of various sizes and to centrally process dust.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] An environmentally friendly construction waste crushing device includes a base, a support box fixedly installed at the bottom of the base, the support box being in communication with the base, a sealing box fixedly installed at the top of the base, an air extraction cylinder installed at one end of the top of the sealing box, a crushing roller rotatably connected to one end inside the base, the crushing roller being drivenly connected to the air extraction cylinder, a conveyor belt provided on the upper surface of the base, a support frame installed inside the sealing box, a drive cylinder installed at the top of the support frame, the output end of the drive cylinder being connected to a pressing box, and the pressing box being mounted on the support frame. On the inner wall of the device, the pressing box is driven and connected to the conveyor belt. The conveyor belt has a support plate inside, which matches the pressing box. This device, through the conveyor belt, facilitates continuous crushing of construction waste. At the same time, the pressing box facilitates the initial crushing of larger construction waste, followed by fine crushing by the crushing rollers, achieving a dual crushing function and ensuring the crushing effect. The initial pressing of the pressing box prevents larger construction waste from failing to enter the crushing rollers, ensuring thorough crushing.

[0009] Preferably, a drive toothed plate is fixedly installed at one end of the side wall of the pressing box, the upper part of the drive toothed plate is a smooth plate, the drive toothed plate is matched with the conveyor belt, and a top plate is fixedly installed at the other end of the side wall of the pressing box; the drive toothed plate and the top plate of this device are both located inside the sealed box, and this device is a sealed connection.

[0010] Preferably, a drive roller is provided on the inner wall of the conveyor belt, a rotating shaft is fixedly installed at the axis of the drive roller, and a drive gear is unidirectionally connected to the outer wall of one end of the rotating shaft, the drive gear being matched with the drive gear plate.

[0011] Preferably, the rotating shaft has a through hole inside, and a stop block is slidably connected inside the through hole. One end of the stop block is triangular in shape, and a drive spring is fixedly installed at one end of the stop block inside the through hole. The other end of the drive spring is fixedly connected to the inner wall of the through hole. The inner wall of the drive gear has an inclined groove that matches the stop block. When the device is in use, when the drive cylinder is started, the pressing box will press down for initial crushing. At this time, the drive gear plate will mesh with the drive gear, and the stop block will extend under the action of the drive spring. At this point, the straight surface of the abutment block is opposite to the straight surface of the inclined groove. When the drive gear is driven to rotate by the drive toothed plate, it will cause the drive gear to drive the rotating shaft to rotate, which in turn drives the drive roller to rotate, driving the conveyor belt and transporting the construction waste above. This achieves a linkage between initial crushing and conveying. As the drive toothed plate continues to descend, the smooth plate on its outer wall will contact the drive gear, preventing the drive gear from rotating further. This is when the pressing box contacts the conveyor belt for crushing. At this time, the pressing box continues to descend while the conveyor belt stops rotating. The crushing chamber facilitates crushing and avoids the phenomenon of the conveyor belt continuously rotating while the crushing chamber is descending, which could lead to insufficient crushing. Furthermore, to prevent the conveyor belt from reversing during the crushing chamber's reset and thus avoiding discontinuous crushing, the drive gear of this device is configured for unidirectional drive. When the drive gear plate resets upwards, the inclined surface of the abutment block aligns with the inclined surface of the chute, compressing the drive spring. At this time, the rotation of the drive gear does not drive the rotating shaft; only during the descent does the conveyor belt rotate, ensuring continuous crushing. The conveyor belt's drive mechanism works in conjunction with the pressing box, only engaging the conveyor belt when crushing is required. This prevents excessive construction waste from being trapped at the feed inlet of the crushing rollers, thus avoiding blockages. It also prevents the crushing rollers from failing to crush larger or smaller pieces of construction waste before initial crushing, ensuring all construction waste is double-crushed. Furthermore, the conveyor belt stops transporting waste when it is about to contact the pressing box, facilitating crushing. The unidirectional drive gear also prevents repeated crushing by the conveyor belt, ensuring efficient waste transport.

[0012] Preferably, the support plate is slidably connected to the inner wall of the sealing box, and a pushing block is slidably connected inside the sealing box. The pushing block is an isosceles trapezoid. The bottom of the abutment plate abuts against the inclined surface of one end of the pushing block, and the inclined surface of the other end of the pushing block abuts against the bottom of one end of the support plate. A tension spring is fixedly installed at the other end of the pushing block, and the other end of the tension spring is fixedly connected to the inner wall of the sealing box. The support plate and the pressing box of this device are arranged opposite each other. When the pressing box descends, the abutment plate will abut against one end of the pushing block, and the pushing block will abut against the support plate to move upward. The support plate abuts against the conveyor belt. When the support plate and the conveyor belt abut against each other, the conveyor belt stops rotating, and the support plate forms a pressing platform. The support plate and the pressing box have a double crushing effect. When the pressing box resets, the support plate resets under the action of gravity to avoid abutting against the conveyor belt. At this time, the tension spring abuts against the pushing block to reset.

[0013] Preferably, a pressing block is fixedly installed at the bottom of the pressing box, and a cleaning mesh plate is slidably connected to the bottom of the pressing box. The pressing block matches the cleaning mesh plate, and multiple support columns are fixedly installed on the top of the cleaning mesh plate. The multiple support columns are fixedly connected to the abutment column, and a cleaning spring is fixedly installed on the outer wall of the abutment column. The other end of the cleaning spring is fixedly connected to the outer wall of the pressing box, and the abutment column matches the support frame. When not in use, the cleaning mesh plate is embedded inside the pressing block. At this time, the outer surface of the bottom of the pressing box is a smooth plane without any unevenness. When the pressing box of this device is crushed, it is crushed by the cleaning mesh plate and the pressing block. When the pressing box is reset, the abutment column will abut against the support frame. The abutment column drives the cleaning mesh plate to move, thereby cleaning the bottom of the pressing box and preventing construction waste from sticking to the outer wall of the pressing box, ensuring the cleaning effect.

[0014] Preferably, a feed box is fixedly installed on the top of the base, the height of the feed box is lower than the height of one end of the conveyor belt, the interior of the feed box is set at an angle, and a cleaning box is provided on the outer wall of the rolling roller;

[0015] The device comprises two crushing rollers, which are installed opposite each other. A linkage shaft is installed at the axis of each crushing roller, and a linkage gear is installed on the outer wall of one end of the linkage shaft. The two crushing rollers are driven and connected by the linkage gear. The linkage shaft is fixedly connected to the output end of a rotary motor, which is installed on the outer wall of the base. A transmission belt is installed on the outer wall of the other end of the linkage shaft. When the device is in use, the rotary motor is started, which drives the linkage shaft to rotate. At this time, under the action of the linkage gear, the two crushing rollers rotate relative to each other. When the crushing rollers are crushing, the cleaning box can clean the crushing rollers to avoid affecting the crushing effect. At the same time, the feed box of the device is set with an internal slant and is lower than the height of the conveyor belt, which facilitates feeding and increases crushing efficiency.

[0016] Preferably, a drive shaft is rotatably connected inside the suction cylinder. A suction wheel is fixedly mounted on the outer wall of the middle section of the drive shaft. Two scraper plates are fixedly mounted on the bottom of the drive shaft, and each scraper plate abuts against the inner and outer walls of the bottom of the suction cylinder. Fixed bevel gears are fixedly mounted on the outer wall of the top of the drive shaft. A drive shaft is rotatably connected inside the suction cylinder. Rotating bevel gears are fixedly mounted on the outer wall of one end of the drive shaft, and the rotating bevel gears mesh with the fixed bevel gears. The outer wall of the other end of the drive shaft is driven by a transmission belt. This device... When the rotating motor rotates, it drives the drive shaft to rotate under the action of the transmission belt. At this time, the drive shaft drives the suction wheel to rotate under the action of the fixed bevel gear and the rotating bevel gear. The suction cylinder will then evacuate the air from the inside of the sealed box. The suction cylinder of this device can be connected to external dust treatment equipment to avoid environmental pollution, centrally treat dust, and prevent harm to workers. At the same time, the operation of the suction component of this device and the crushing work together to save a lot of resources. In addition, when the suction cylinder of this device is evacuating air, the bottom of it is scraped by a scraper to avoid blockage.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This device, through the conveyor belt, facilitates continuous crushing of construction waste. Simultaneously, the pressing box facilitates the initial crushing of larger construction waste, followed by fine crushing by the rollers, achieving a dual crushing function and ensuring optimal crushing results. The initial pressing of the pressing box prevents larger construction waste from failing to enter the rollers, guaranteeing thorough crushing.

[0019] 2. The conveyor belt of this device can be driven in conjunction with the pressing box to achieve a linkage effect. The conveyor belt will only be driven when crushing is required, which can avoid a large amount of construction waste being squeezed into the feed inlet of the crushing roller, thus preventing blockage. At the same time, it can also avoid conveying construction waste that has not been initially crushed, which would cause the crushing roller to be unable to crush larger or smaller pieces of waste. This ensures that all construction waste is double-crushed. In addition, when the pressing box and the conveyor belt are about to come into contact, the conveyor belt will stop conveying, which is convenient for crushing. Furthermore, under the action of the unidirectional drive gear, the conveyor belt of this device can avoid repeated crushing, thus ensuring the conveying of waste.

[0020] 3. The support plate and the pressing box of this device are set opposite each other. When the pressing box is lowered, the top plate will abut against one end of the pushing block. At this time, the pushing block will abut against the support plate and move upward. The support plate and the conveyor belt abut against each other. When the support plate and the conveyor belt abut against each other, the conveyor belt stops rotating. The support plate forms a pressing platform, and the support plate and the pressing box have a double crushing effect.

[0021] 4. When the pressing box is reset, the abutment column will abut against the support frame. The abutment column will drive the cleaning mesh plate to move, thereby cleaning the bottom of the pressing box and preventing construction waste from sticking to the outer wall of the pressing box, thus ensuring the cleaning effect.

[0022] 5. The two crushing rollers of this device rotate relative to each other. When the crushing rollers are crushing, the cleaning box can clean the crushing rollers to avoid affecting the crushing effect. At the same time, the feed box of this device is set with an internal slant and is lower than the height of the conveyor belt, which can facilitate feeding and increase crushing efficiency.

[0023] 6. When the rotating motor of this device rotates, it will drive the drive shaft to rotate under the action of the transmission belt. At this time, the drive shaft drives the suction wheel to rotate under the action of the fixed bevel gear and the rotating bevel gear. At this time, the suction cylinder will evacuate the air inside the sealed box. The suction cylinder of this device can be connected to external dust treatment equipment to avoid environmental pollution, centralize the dust treatment, and prevent harm to workers. At the same time, the operation of the suction component of this device and the crushing will form a linkage effect, saving a lot of resources. In addition, when the suction cylinder of this device is evacuating air, the bottom of it is scraped by the scraper to avoid blockage. Attached Figure Description

[0041] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0042] An environmentally friendly construction waste crushing device, as shown in the attached document. Figure 1-4 As shown, the system includes a base 1, a support box 3 fixedly installed at the bottom of the base 1, the support box 3 and the base 1 being in communication, and a sealing box 2 fixedly installed at the top of the base 1. An air extraction cylinder 4 is installed at one end of the top of the sealing box 2. (See attached diagram.) Figure 9 As shown, a crushing roller 5 is rotatably connected to one end of the base 1. The crushing roller 5 is driven by the air extraction cylinder 4. A conveyor belt 6 is provided on the upper surface of the base 1. A support frame 7 is installed inside the sealed box 2. A drive cylinder 8 is installed on the top of the support frame 7. The output end of the drive cylinder 8 is connected to the pressing box 9. The pressing box 9 is installed on the inner wall of the support frame 7. The pressing box 9 is driven by the conveyor belt 6. A support plate 10 is provided inside the conveyor belt 6. The support plate 10 matches the pressing box 9. This device, through the setting of the conveyor belt 6, can facilitate continuous crushing of construction waste. At the same time, through the setting of the pressing box 9, it can facilitate the initial crushing of larger construction waste. Then, the crushing roller 5 performs fine crushing, realizing the function of dual crushing and ensuring the crushing effect. Through the initial crushing of the pressing box 9, this device can avoid the phenomenon that larger construction waste cannot enter the interior of the crushing roller 5, ensuring the thorough crushing effect.

[0043] As attached Figure 3 As shown, a drive toothed plate 11 is fixedly installed on one end of the side wall of the pressing box 9. The upper part of the drive toothed plate 11 is a smooth plate. The drive toothed plate 11 is matched with the conveyor belt 6. A top plate 12 is fixedly installed on the other end of the side wall of the pressing box 9. The drive toothed plate 11 and the top plate 12 of this device are both located inside the sealed box 2. This device is a sealed connection.

[0044] As attached Figure 3-4 As shown, a drive roller 601 is provided on the inner wall of the conveyor belt 6. A rotating shaft 602 is fixedly installed at the axis of the drive roller 601. A drive gear 603 is unidirectionally connected to the outer wall of one end of the rotating shaft 602. The drive gear 603 is matched with the drive tooth plate 11.

[0045] As attached Figure 5As shown, a through hole 604 is provided inside the rotating shaft 602. A stop block 605 is slidably connected inside the through hole 604. One end of the stop block 605 is triangular in shape. A drive spring 606 is fixedly installed at one end of the stop block 605 inside the through hole 604. The other end of the drive spring 606 is fixedly connected to the inner wall of the through hole 604. A groove 607 is provided on the inner wall of the drive gear 603, and the groove 607 matches the stop block 605. When the device is in use, when the drive cylinder 8 is started, the pressing box 9 will press down for initial crushing. At this time, the drive tooth plate 11 will mesh with the drive gear 603. The stop block 605 is then supported by the drive spring 606. When the pressure plate 605 extends under the action of the drive gear 603, the straight surface of the abutment block 605 is opposite to the straight surface of the inclined groove 607. This causes the drive gear 603 to rotate when driven by the drive toothed plate 11, which in turn causes the drive gear 603 to rotate the rotating shaft 602. This, in turn, causes the rotating shaft 602 to rotate the drive roller 601, driving the conveyor belt 6 to transport the construction waste above it, achieving a linkage effect between initial crushing and conveying. When the drive toothed plate 11 continues to descend, the smooth plate on its outer wall will contact the drive gear 603, preventing the drive gear 603 from rotating during the continuous descent of the drive toothed plate 11. This is when the pressing box 9 is about to contact the conveyor belt 6 for crushing. As the conveyor belt 6 stops rotating during the continuous descent, the crushing box 9 facilitates crushing, preventing the conveyor belt from continuously rotating and causing incomplete crushing. Furthermore, to prevent the conveyor belt 6 from reversing during the reset of the crushing box 9, thus avoiding discontinuous crushing, the drive gear 603 is designed for unidirectional drive. When the drive tooth plate 11 resets upwards, the inclined surface of the abutment block 605 is opposite to the inclined surface of the inclined groove 607, compressing the drive spring 606. At this time, the rotation of the drive gear 603 does not drive the rotating shaft 602 to rotate; only during descent will the conveyor belt 6 be driven to rotate. The device features a dynamic conveyor system to ensure continuous crushing. The conveyor belt 6 of this device is linked with the pressing box 9, and it only drives the conveyor belt 6 when crushing is required. This prevents a large amount of construction waste from being squeezed into the feed inlet of the crushing roller 5, thus preventing blockage. It also avoids conveying construction waste that has not been initially crushed, which could result in the crushing roller 5 being unable to crush larger or smaller pieces of waste. This ensures that all construction waste is double-crushed. Furthermore, when the pressing box 9 and the conveyor belt 6 are about to come into contact, the conveyor belt 6 will stop conveying, facilitating crushing. Under the action of the one-way drive gear 603, the conveyor belt 6 can be prevented from repeatedly crushing the waste, ensuring the smooth transport of the waste.

[0046] As attached Figure 4 and attached Figure 6As shown, the support plate 10 is slidably connected to the inner wall of the sealing box 2. A push block 608 is slidably connected inside the sealing box 2. The push block 608 is an isosceles trapezoid. The bottom of the abutment plate 12 abuts against the inclined surface of one end of the push block 608, and the inclined surface of the other end of the push block 608 abuts against the bottom of one end of the support plate 10. A tension spring 609 is fixedly installed at the other end of the push block 608, and the other end of the tension spring 609 is fixedly connected to the inner wall of the sealing box 2. The support plate 10 of this device is positioned opposite the pressing box 9. When the pressing box 9 descends, this will cause… The top plate 12 abuts against one end of the push block 608. At this time, the push block 608 will abut against the support plate 10 and move upward. The support plate 10 and the conveyor belt 6 abut against each other. When the support plate 10 and the conveyor belt 6 abut against each other, the conveyor belt 6 stops rotating. The support plate 10 forms a pressing platform. The support plate 10 and the pressing box 9 have a double crushing effect. When the pressing box 9 resets, the support plate 10 resets under the action of gravity to avoid abutting against the conveyor belt 6. At this time, the tension spring 609 abuts against the push block 608 to reset.

[0047] As attached Figure 7-8 As shown, a pressing block 901 is fixedly installed at the bottom of the pressing box 9, and a cleaning screen 902 is slidably connected to the bottom of the pressing box 9. The pressing block 901 matches the cleaning screen 902. Multiple support columns 905 are fixedly installed on the top of the cleaning screen 902. The multiple support columns 905 are fixedly connected to the abutment column 903. A cleaning spring 904 is fixedly installed on the outer wall of the abutment column 903. The other end of the cleaning spring 904 is fixedly connected to the outer wall of the pressing box 9. The abutment column 903 matches the support frame 7. The cleaning screen 901... 2. When not in use, it is embedded inside the pressing block 901. At this time, the outer surface of the bottom of the pressing box 9 is a smooth plane without any unevenness. When the pressing box 9 of this device is crushed, it is crushed by the cleaning mesh plate 902 and the pressing block 901. When the pressing box 9 is reset, the abutment column 903 will abut against the support frame 7. The abutment column 903 drives the cleaning mesh plate 902 to move, thereby cleaning the bottom of the pressing box 9 and avoiding the phenomenon of construction waste sticking to the outer wall of the pressing box 9, thus ensuring the cleaning effect.

[0048] As attached Figure 1-2 and attached Figure 9 As shown, a feed box 501 is fixedly installed on the top of the base 1. The height of the feed box 501 is lower than the height of one end of the conveyor belt 6. The inside of the feed box 501 is set to be inclined. A cleaning box 502 is provided on the outer wall of the rolling roller 5.

[0049] There are two crushing rollers 5, which are installed opposite each other. A linkage shaft 503 is installed at the axis of the crushing roller 5. A linkage gear 504 is installed on the outer wall of one end of the linkage shaft 503. The two crushing rollers 5 are driven and connected by the linkage gear 504. The linkage shaft 503 is fixedly connected to the output end of the rotating motor 505, which is installed on the outer wall of the base 1. A transmission belt 506 is installed on the outer wall of the other end of the linkage shaft 503. When the device is in use, the rotating motor 505 is started, which drives the linkage shaft 503 to rotate. At this time, under the action of the linkage gear 504, the two crushing rollers 5 rotate relative to each other. When the crushing rollers 5 are crushing, the cleaning box 502 can clean the crushing rollers 5 to avoid affecting the crushing effect. At the same time, the feed box 501 of the device is set to be inclined internally and lower than the height of the conveyor belt 6, which facilitates feeding and increases crushing efficiency.

[0050] As attached Figure 10 As shown, a drive shaft 402 is rotatably connected inside the suction cylinder 4. A suction wheel 401 is fixedly mounted on the outer wall of the middle part of the drive shaft 402. Two scraper plates 406 are fixedly mounted at the bottom of the drive shaft 402, and these scraper plates 406 abut against the inner and outer walls of the bottom of the suction cylinder 4, respectively. Fixed bevel gears 403 are fixedly mounted on the outer wall of the top of the drive shaft 402. A drive shaft 404 is rotatably connected inside the suction cylinder 4. A rotating bevel gear 405 is fixedly mounted on the outer wall of one end of the drive shaft 404, and the rotating bevel gear 405 meshes with the fixed bevel gear 403. The outer wall of the other end of the drive shaft 404 is driven by a transmission belt 506. This device rotates... When the motor 505 rotates, it drives the drive shaft 404 to rotate under the action of the transmission belt 506. At this time, the drive shaft 404 drives the suction wheel 401 to rotate under the action of the fixed bevel gear 403 and the rotating bevel gear 405. At this time, the suction cylinder 4 will evacuate the air inside the sealed box 2. The suction cylinder 4 of this device can be connected to external dust treatment equipment to avoid environmental pollution, centrally treat dust, and prevent damage to workers. At the same time, the operation of the suction component of this device and the crushing form a linkage effect, saving a lot of resources. When the suction cylinder 4 of this device is evacuating air, the bottom of it is scraped by the scraper 406 to avoid blockage.
