Description

Technical Field

[0001] This utility model relates to the technical field of construction waste treatment equipment, and in particular to a recycled concrete construction waste aggregate crushing equipment. Background Technology

[0002] Construction waste aggregate crushing equipment can be applied to roads, buildings, and landscape projects. It has environmental benefits such as reducing landfill volume and dust pollution, economic benefits such as reducing material costs and creating new industrial value, and social benefits such as demonstrating resource recycling and enhancing the city's image.

[0003] A search revealed Chinese Patent Publication No. CN219836606U, which discloses a construction waste recycled aggregate separation device, belonging to the technical field of construction waste treatment equipment. This separation device includes a crushing component and a coarse aggregate conveying mechanism. The crushing component includes a crushing box and a crushing mechanism. The crushing box has an inlet at the top, a first outlet at the bottom, and a second outlet on its side wall. A fine aggregate filter screen is inclinedly arranged inside the crushing box near the first outlet. The coarse aggregate conveying mechanism includes a frame, a conveyor belt, and multiple conveying rollers. The multiple conveying rollers are rotatably mounted on the frame and connected by the conveyor belt. Multiple magnetic blocks are installed inside the conveyor belt. A scraper is located on the side of the frame away from the second outlet, with its scraping side abutting against the outer surface of the conveyor belt. This equipment separates the crushed construction waste recycled aggregate into fine aggregate, coarse aggregate, and metal blocks, which are then recycled separately, achieving the reuse of recycled resources in a green and environmentally friendly manner.

[0004] The aforementioned patent specification mentions that "both crushing rollers 10 are equipped with crushing blades for crushing aggregate falling from the feed inlet 2. The relative rotation of the two crushing rollers 10 can be driven by a crushing motor 11, and both crushing motors 11 can be installed on the crushing box 1. The output ends of the two crushing motors 11 pass through the crushing box 1 and are connected to one end of the two crushing rollers 10 respectively. During installation, the axes of the two crushing rollers 10 are parallel to the top of the crushing box 1, and the axes of the two crushing rollers 10 are parallel to each other. A gap is left between the two crushing rollers 10 so that the crushed aggregate can fall from between the two crushing rollers 10 onto the fine aggregate filter screen 5." Although the aforementioned patent can achieve the crushing effect of construction waste, it cannot avoid the dust pollution of the outside air generated during the crushing process. Therefore, a recycled concrete construction waste aggregate crushing equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a recycled concrete construction waste aggregate crushing equipment, which aims to improve the problem that the existing technology cannot reduce dust pollution of the outside air.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A recycled concrete construction waste aggregate crushing equipment includes a base plate, a protective mechanism fixedly connected to the top of the base plate, a cover opening mechanism fixedly connected to the top of the protective mechanism, a dust conveying mechanism fixedly connected to the outside of the protective mechanism, multiple vibrating screening mechanisms connected to the outside of the protective mechanism, a crushing mechanism fixedly connected to one side of the protective mechanism, and a crushed material conveying mechanism fixedly connected to the outside of the protective mechanism.

[0008] The dust conveying mechanism includes two air pumps, each of which has a conveying pipe fixedly connected inside. A collection box is fixedly connected to the end of the conveying pipe away from the air pump. A limiting component is fixedly connected inside the collection box, and a filter plate is slidably connected inside the limiting component.

[0009] Through the above technical solution, the dust transmission mechanism of the recycled concrete construction waste aggregate crushing equipment plays a crucial role in the operation of the equipment. When the equipment processes construction waste and generates a large amount of dust inside the protective mechanism, two suction pumps quickly start. With their strong suction, the dust is drawn into the transmission pipe. Powered by the operation of the suction pumps, the dust is guided along the transmission pipe to the collection box. In the collection box, the limiting component fixes the filter plate. The filter plate intercepts the transmitted dust, allowing the filtered clean air to be discharged, greatly reducing dust pollution to the external environment. As the usage time increases, if the filter plate needs to be replaced, simply operate the limiting component to detach it from the filter plate, remove the old plate and replace it with a new one, and then reinstall the limiting component. In this way, the filter plate can continue to filter dust efficiently, ensuring that the dust transmission mechanism is always in good operating condition, creating a clean working environment for the entire equipment, and effectively guaranteeing the continuous, stable and environmentally friendly operation of the equipment.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a limiting frame, the outer side of which is fixedly connected to the inside of the collection box, a limiting block is slidably connected to the inside of the limiting frame, a sliding rod is slidably connected to the inside of the limiting block, and a spring is fixedly connected to the inner side of the sliding rod.

[0012] The above technical solution facilitates the installation and replacement of the filter plate. The limiting frame is fixed inside the collection box and provides support. When installing the filter plate, the sliding rod is pulled to overcome the elastic force of the second spring, and the limiting block is slid into the limiting frame. When the sliding rod is released, the second spring pushes it into the slot, stabilizing the limiting block and thus fixing the filter plate. When replacing, the sliding rod is pulled again to disengage it from the slot, and the limiting block is no longer fixed, allowing it and the filter plate to be easily removed from the limiting frame. The whole process is simple to operate, ensuring stable installation of the filter plate and achieving efficient replacement, thus meeting the equipment's dust filtration requirements.

[0013] As a further description of the above technical solution:

[0014] The protective mechanism includes a housing, and a discharge port is fixedly connected to the outer side of the housing;

[0015] Through the above technical solution: when the protection mechanism is working, the outer shell provides a protective space for the entire equipment, preventing construction waste from splashing during the crushing process. After crushing, the material is screened and discharged from the discharge port that is fixedly connected to the outside of the outer shell if it meets the discharge conditions. The discharge port ensures that the material can be output in an orderly manner, maintaining the continuity and efficiency of the crushing operation of the equipment.

[0016] As a further description of the above technical solution:

[0017] The opening mechanism includes a cylinder, a connecting block is fixedly connected to the driving end of the cylinder, and a cover is fixedly connected to the end of the connecting block away from the cylinder.

[0018] Through the above technical solution: when the opening mechanism is working, the cylinder starts, and its driving end drives the connecting block fixed thereto to move. The connecting block will then pull or push the cover fixed away from the cylinder. When construction waste needs to be put into the equipment, the cylinder drives the cover to open. After the feeding is completed, the cylinder drives in the opposite direction to close the cover, preventing dust from overflowing during the crushing process and ensuring work safety and environmental cleanliness.

[0019] As a further description of the above technical solution:

[0020] The crushing mechanism includes a motor and a transmission gear. The drive end of the motor is fixedly connected to a rotating gear. The outer side of the rotating gear is meshed with the outer side of the transmission gear. A crushing wheel is fixedly connected inside the transmission gear.

[0021] With the above technical solution: when the crushing mechanism is running, once the motor starts, its drive end drives the rotating gear to rotate. Since the rotating gear meshes with the outer side of the transmission gear, the rotation of the rotating gear will drive the transmission gear to rotate. The transmission gear has a crushing wheel fixed inside. The rotation of the transmission gear causes the crushing wheel to rotate as well, thereby crushing the incoming construction waste.

[0022] As a further description of the above technical solution:

[0023] The vibration screening mechanism includes a vibration motor, a screening plate two is fixedly connected inside the outer shell, a screening plate one is fixedly connected inside the outer shell, a fixing plate is fixedly connected inside the outer shell, and multiple springs one are fixedly connected to the outer side of the outer shell.

[0024] Through the above technical solution: when the vibrating screening mechanism is working, the vibrating motor starts and generates strong vibration, which drives the entire outer shell and internal structure to vibrate. The material crushed by the crushing wheel falls onto the inclined screening plate two. Under the action of vibration, small particles pass through the holes of screening plate two and fall onto screening plate one for further screening, while large particles slide towards the discharge port. Small particles on screening plate one fall onto the fixed plate for discharge, while large particles re-enter the discharge port. Spring one assists in buffering and shock absorption, ensuring a stable and efficient screening process and preventing material blockage.

[0025] As a further description of the above technical solution:

[0026] The material conveying mechanism includes a second motor, and the drive end of the second motor is fixedly connected to a auger conveyor.

[0027] Through the above technical solution: when the crushing material conveying mechanism is working, motor 2 is turned on, and its drive end drives the connected auger to operate. The crushed material that does not meet the standard after screening at the discharge port is pushed by the spiral blades of the auger and conveyed along the predetermined path, and sent back to the crushing wheel for further crushing, so as to realize the crushed material recycling process and improve the quality of the finished aggregate.

[0028] As a further description of the above technical solution:

[0029] The cylinder is fixedly connected to the top of the housing, and the outer side of the vibration motor is fixedly connected to the bottom of the housing;

[0030] The above technical solution involves a cylinder fixed to the top of the outer casing. When started, its drive end moves, which drives the cover to open or close through the connecting structure, facilitating material feeding and dust prevention. The vibration motor is fixed to the bottom of the outer casing. When running, it generates vibration force, causing the entire outer casing and internal components to vibrate, which helps with material screening and transmission, and ensures efficient operation of all aspects of the equipment.

[0031] This utility model has the following beneficial effects:

[0032] In this invention, an air pump is used in conjunction with a transmission pipe, which in turn is used with a collection box, which is used with a limiting frame, and the limiting frame is used with a filter plate. This allows for the filtration of dust, reducing the harm caused by dust to workers. It effectively reduces the amount of dust inhaled by workers, lowers the risk of respiratory diseases such as pneumoconiosis, bronchitis, and asthma, protects normal respiratory function, and enables workers to maintain good physical condition in the long term, avoiding the impact of occupational diseases on their quality of life and work ability.

[0033] In this invention, a vibrating motor is used in conjunction with a housing, which in turn is used with a second screening plate. The first screening plate and the vibrating motor are combined, the second screening plate is used with a discharge port, and the discharge port is used with a conveyor belt. This enables the cyclic crushing of construction waste. The vibrating motor causes the housing and the screening plate to vibrate, allowing the crushed construction waste to move quickly on the screening plate, thus accelerating the screening speed. This allows small particles that meet the requirements to quickly fall through the holes in the screening plate, while large particles that do not meet the requirements to quickly move towards the discharge port and enter the next round of crushing. Overall, this improves the efficiency of material processing. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figures 1 to 3 This utility model provides an embodiment of a recycled concrete construction waste aggregate crushing equipment, including a base plate 1 with a stable structure that effectively distributes the overall weight of the equipment, ensuring that the equipment remains stable during operation and providing a solid foundation for the normal operation of each mechanism. A protective mechanism 2 is fixedly connected to the top of the base plate 1. The protective mechanism 2 has a closed structure, which can control the material splashing and dust diffusion generated during the crushing process within the equipment, greatly protecting the safety of the surrounding environment and operators. A cover opening mechanism 3 is fixedly connected to the top of the protective mechanism 2. After the cover opening mechanism 3 is activated, it can quickly and accurately open the cover 303, providing convenience for feeding construction waste into the protective mechanism 2. The operation is simple and efficient. A dust transmission mechanism 7 is fixedly connected to the outside of the protective mechanism 2. The dust transmission mechanism 7 can capture and process a large amount of dust raised during the operation of the equipment in a timely manner, significantly improving the air quality in the working area and reducing the harm of dust to the environment and personnel health.

[0042] Multiple vibrating screening mechanisms 5 are connected to the outside of the protection mechanism 2. When the vibrating screening mechanism 5 is turned on, the high-frequency vibration generated can make the crushed material move quickly on the screening plate, greatly improving the screening efficiency and ensuring that the material is accurately separated according to the particle size. A crushing mechanism 4 is fixedly connected to one side of the protection mechanism 2. When the crushing mechanism 4 is running, it can quickly and effectively crush the input construction waste into aggregates of different particle sizes to meet the needs of subsequent processing. A crushed material conveying mechanism 6 is fixedly connected to the outside of the protection mechanism 2. The crushed material conveying mechanism 6 can accurately convey crushed materials that do not meet the standard particle size from the discharge port 202 back to the crushing area to realize the recycling of crushed materials and improve the finished quality of aggregates. The dust conveying mechanism 7 includes two suction pumps 701. The suction pumps 701 have strong suction and can form a strong negative pressure at the moment of start-up, quickly drawing the dust out of the protection mechanism 2.

[0043] Both air pumps 701 are internally connected to a transmission pipe 702. The transmission pipe 702 is reasonably laid out to ensure that the dust is transported smoothly and efficiently to the next step. The end of the transmission pipe 702 away from the air pump 701 is fixedly connected to a collection box 703. The collection box 703 has a large volume and can store the collected dust for a long time, reducing the cleaning frequency and ensuring the continuity of dust collection. The collection box 703 is internally connected to a limiting component 704. The limiting component 704 is cleverly designed to securely limit the parts and can be easily and quickly removed and installed. The limiting component 704 is internally connected to a filter plate 705. The filter plate 705 has excellent filtration effect and can effectively intercept fine particles in the dust, allowing the purified air to be discharged and reducing dust pollution to the environment.

[0044] Specifically, the base plate 1 features a specially thickened design and a stable triangular support structure, effectively distributing the overall weight of the equipment. Even under high-speed operation and significant vibration, it ensures the equipment remains stable, providing a solid foundation for the normal operation of all mechanisms. A protective mechanism 2 is fixedly connected to the top of the base plate 1. This fully enclosed mechanism, with seamless connections on all sides, effectively controls material splashes and dust dispersion within the equipment during the construction waste crushing process, greatly protecting the safety of the surrounding environment and operators, and significantly reducing the risk of respiratory illnesses caused by dust. A cover-opening mechanism 3 is also fixedly connected to the top of the protective mechanism 2. Utilizing advanced hydraulic control technology, the cover 303 can be opened quickly and precisely after startup, and the opening angle can be flexibly adjusted. This facilitates the feeding of construction waste into the protective mechanism 2, making the operation simple and efficient, greatly shortening the feeding time each time and improving production efficiency. A dust transmission mechanism 7 is fixedly connected to the outside of the protective mechanism 2. The dust transmission mechanism 7 is equipped with a highly sensitive dust sensor, which can promptly capture and handle the large amount of dust raised during equipment operation. Through two powerful suction pumps 701, a strong negative pressure can be formed instantly upon startup, quickly extracting the dust from the protective mechanism 2, significantly improving the air quality in the working area and reducing the harm of dust to the environment and personnel health.

[0045] The limiting component 704 includes a limiting frame 7041. The limiting frame 7041 is designed and constructed robustly, forming a reliable support frame inside the collection box 703, providing a stable foundation for subsequently installed components. The outer side of the limiting frame 7041 is fixedly connected to the inside of the collection box 703. A limiting block 7042 is slidably connected inside the limiting frame 7041. This tight connection ensures that the device will not loosen due to vibration or other external forces during operation, guaranteeing the stability of the entire limiting component 704. A sliding rod 7 is slidably connected inside the limiting block 7042. 044, the limiting block 7042 slides smoothly within the limiting frame 7041 and can flexibly enter and exit the limiting frame 7041 according to operational needs, facilitating the installation and disassembly of the filter plate 705. The inner side of the sliding rod 7044 is fixedly connected to the second spring 7043, which has a suitable elastic coefficient. When no external force is applied, the sliding rod 7044 can be pushed out and locked into the slot of the limiting frame 7041, thereby firmly fixing the limiting block 7042. When an external force is applied to overcome the spring force, the sliding rod 7044 can be retracted, facilitating the movement of the limiting block 7042.

[0046] Specifically, the limiting component 704 includes a limiting frame 7041. The limiting frame 7041 employs a reinforced frame design, resulting in a highly stable structure. Inside the collection box 703, it acts like a solid fortress, forming a reliable support frame. This not only provides a stable foundation for subsequent installations of components such as the limiting block 7042, but also resists minor deformations during equipment operation. The outer side of the limiting frame 7041 is fixedly connected to the inside of the collection box 703 using a precise welding process. This tight connection acts like a strong bond, ensuring that even under strong vibrations or other external forces during equipment operation, there will be no loosening, guaranteeing the stability of the entire limiting component 704. The limiting block 7042 is slidably connected inside the limiting frame 7041, and its surface is finely polished, ensuring... The sliding of the block 7042 within the limiting frame 7041 is as smooth as flowing water, allowing it to flexibly enter and exit the limiting frame 7041 according to operational needs. Operators can easily install and remove the filter plate 705 with a simple push and pull. The limiting block 7042 is internally connected to a sliding rod 7044, and a second spring 7043 is fixedly connected to the inner side of the sliding rod 7044. The second spring 7043 has a suitable elastic coefficient, which, when not subjected to external force, can steadily push the sliding rod 7044 out, making it accurately engage with the slot in the limiting frame 7041, thereby firmly fixing the limiting block 7042. When external force is applied to overcome the spring force, the sliding rod 7044 can smoothly retract, facilitating the movement of the limiting block 7042. The entire operation process is simple and convenient, greatly improving the replacement efficiency of the filter plate 705.

[0047] The protective mechanism 2 includes an outer shell 201, which has a closed structure and can effectively block the splashes and dust generated during the crushing process of construction waste, creating a relatively independent and safe space for the internal operation of the equipment, greatly reducing the impact on the surrounding environment and personnel. The outer shell 201 is fixedly connected to the discharge port 202. The discharge port 202 is reasonably designed so that the material that meets the particle size requirements after crushing and screening can be smoothly discharged from the discharge port 202 under the action of gravity and internal vibration of the equipment, ensuring the efficiency and continuity of the material output link of the equipment, and making the entire crushing process proceed in an orderly manner.

[0048] The opening mechanism 3 includes a cylinder 301. The cylinder 301 is powerful and has a fast response speed, which can start quickly and generate a stable driving force, providing a strong guarantee for the opening and closing of the cover 303. The cylinder 301 is fixedly connected to the top of the outer shell 201. This installation method allows the cylinder 301 to maintain good stability and vertical force when driving the cover 303, ensuring that the opening and closing action of the cover 303 is accurate. The driving end of the cylinder 301 is fixedly connected to a connecting block 302. The connecting block 302 plays a role in stably transmitting the driving force of the cylinder 301, ensuring that there will be no deviation or loosening during the power transmission process. The end of the connecting block 302 away from the cylinder 301 is fixedly connected to the cover 303. When the cylinder 301 drives the connecting block 302 to move, the cover 303 can flexibly open or close the outer shell 201. When open, it is convenient to put construction waste in, and when closed, it can effectively prevent dust from flying out.

[0049] Specifically, the protective mechanism 2 and the opening mechanism 3 work together to ensure the operation of the equipment. The outer shell 201 of the protective mechanism 2 is made of seamless welding to form a fully enclosed structure. When crushing construction waste, it acts like a sturdy shield, strictly blocking splashed materials and dust. It not only creates a safe and independent space for internal operation, reducing pollution to the surrounding environment, but also protects operators from injury by splashes and reduces the health threat of dust. The discharge port 202 on its outer side is carefully designed to be in the optimal tilt position. With the help of gravity and internal vibration of the equipment, materials that meet the particle size can be discharged smoothly, ensuring efficient and continuous material output and promoting the orderly development of the crushing process. The cylinder 301 of the opening mechanism 3 has excellent performance, strong power and fast response. It is fixed to the top of the outer shell 201. When driving the cover 303, it has good stability and vertical and precise force, eliminating the jamming when opening and closing. The connecting block 302 is precisely assembled to stably transmit the driving force. The cover 303 opens and closes flexibly. Opening it makes it easy to feed materials, and closing it prevents dust from escaping and keeps the working environment clean.

[0050] The crushing mechanism 4 includes a motor 401 and a transmission gear 403. The motor 401 has high power and stable speed, providing continuous and strong power for the crushing operation and ensuring the efficient operation of the entire crushing process. The drive end of the motor 401 is fixedly connected to a rotating gear 402. After the motor 401 is started, the rotating gear 402 can quickly and accurately follow the drive of the motor 401 to rotate, and output power stably. The outer side of the rotating gear 402 is meshed with the outer side of the transmission gear 403. This meshing method has high transmission efficiency and good precision. The rotation of the rotating gear 402 can smoothly and efficiently drive the transmission gear 403 to rotate synchronously, ensuring that there is no slippage or power loss during the power transmission process. The inside of the transmission gear 403 is fixedly connected to a crushing wheel 404. When the transmission gear 403 rotates, it can drive the crushing wheel 404 to rotate at high speed. The crushing wheel 404 generates a strong impact force by rotating at high speed, which quickly and effectively crushes the input construction waste into aggregate of the required particle size.

[0051] Reference Figure 1 , Figure 2 and Figure 4 The vibrating screening mechanism 5 includes a vibrating motor 501. The vibration frequency and amplitude of the vibrating motor 501 can be precisely adjusted. After starting, it can produce a uniform and strong vibration effect, providing powerful force for material screening. The vibrating motor 501 is fixedly connected to the bottom of the outer shell 201. This installation method allows the outer shell 201 to be evenly stressed, allowing the internal materials to vibrate fully and effectively avoiding material accumulation and blockage. A second screening plate 504 is fixedly connected inside the outer shell 201. Under the action of vibration, the second screening plate 504 can quickly and accurately perform preliminary screening of materials, allowing smaller particles to pass through smoothly, while larger particles remain on the plate for further processing. The internal fixed connection of the outer shell 201 is a screening plate 503, which can further finely screen the material after screening plate 504, improve the screening accuracy, and ensure that the particle size of the final output material meets the requirements. The internal fixed connection of the outer shell 201 is a fixing plate 502, which can stably support the fine material after screening in a vibration environment, and use its own tilt angle to smoothly discharge the material from the outer shell 201 in conjunction with the vibration. The outer side of the outer shell 201 is fixedly connected to multiple springs 505, which play a buffering and shock absorption role, reducing the impact of vibration on the outside when the vibration motor 501 is working, while ensuring the stability of the vibration screening of the outer shell 201.

[0052] The material conveying mechanism 6 includes a second motor 601, which has good speed regulation performance and stable power output. After starting, it can quickly reach a suitable speed, providing stable and continuous power support for material conveying. The drive end of the second motor 601 is fixedly connected to a auger conveyor 602. When the second motor 601 is running, the auger conveyor 602 can efficiently convey the non-standard crushed material in the discharge port 202 upward. The conveying process is smooth and stable, and the crushed material can be accurately sent back to the top of the crushing wheel 404 for further crushing, realizing the recycling of crushed material and improving the overall production efficiency.

[0053] Specifically, the crushing mechanism 4 features a powerful motor 401 with a stable speed supporting long-term operation and efficient power output. Upon startup, the rotating gear 402, thanks to its high-precision assembly, quickly and accurately transmits power to the transmission gear 403. The special tooth profiles of these two gears mesh tightly, resulting in high transmission efficiency and preventing slippage. The transmission gear 403 drives the crushing wheel 404 to rotate at high speed, and its special cutting edge generates a powerful impact force, efficiently crushing construction waste into aggregates of the required particle size. The vibrating screening mechanism 5, with its vibrating motor 501, utilizes an intelligent adjustment device to adjust the vibration frequency and amplitude according to the material characteristics. Installed at the bottom of the outer casing 201, it ensures uniform vibration throughout the equipment. Uniform vibration causes the material to tumble on the second screening plate 504, allowing small-diameter materials to pass through quickly. The first screening plate 503 uses a denser mesh for secondary screening, ensuring accurate output. The fixed plate 502, with an optimized tilt angle, receives and discharges fine materials during vibration. The first spring 505 buffers and reduces shock, ensuring stable screening. The crushed material conveying mechanism 6 uses a second motor 601 with precise speed adjustment to quickly reach the appropriate speed. The spiral blades of the auger conveyor 602 are reasonably designed, and driven by the second motor 601, they smoothly and efficiently send the unqualified crushed material from the discharge port 202 back to the top of the crushing wheel 404, realizing crushed material circulation and improving the quality of finished aggregates and production efficiency.

[0054] Working principle: When workers need to crush stones in construction waste, they can simultaneously start the cylinder 301, rotating gear 402, and vibrating motor 501. The cylinder 301 then lifts the cover 303 via the connecting block 302, opening the outer casing 201. Stones from the construction waste can then be fed into the casing 201. Driven by the rotating gear 402, which is connected to two transmission gears 403, and each transmission gear 403 has a crushing wheel 404 fixed inside, the stones are crushed. The crushed stones fall onto the top of the screening plate 504. The entire casing 201 then vibrates due to the start of the vibrating motor 501, preventing the crushed stones from clogging the top of the screening plate 504. Screening plate 2 504 is inclined inside the outer shell 201, which makes it easier for stones to fall into the discharge port 202. The crushed stones larger than the holes in screening plate 2 504 will fall into the discharge port 202, while those smaller than the holes in screening plate 2 504 will fall to the top of screening plate 1 503. Then, like screening plate 2 504, those smaller than the holes in screening plate 1 503 will fall to the top of fixing plate 502. Through the inclination angle of fixing plate 502 and the vibration of vibrating motor 501, the stones are discharged from the inner shell 201. The stones larger than the holes in screening plate 1 503 will fall into the discharge port 202. Then, motor 2 601 is started, which drives the auger transmission 602, so that the stones inside the discharge port 202 are transported up and then discharged to the top of crushing wheel 404 for further crushing.

[0055] When stones from construction waste are poured into the interior of the outer casing 201, a large amount of dust is generated inside. At this point, cylinder 301 is activated to close the cover 303, preventing dust from escaping. Then, two vacuum pumps 701 are activated to extract the dust, which is then transferred through transmission pipe 702 to the collection box 703. The dust is then filtered by the filter plate 705 inside the transmission pipe 702, reducing its impact on the outside. When the filter plate 705 needs to be replaced, the sliding rod 7044 can be pulled using the handle connected to its outer side. Simultaneously, both sliding rods 7044 are pulled inwards towards the limiting block 7042, causing the outer side of the sliding rod 7044 to... Slide the slider into the interior of the limiting block 7042, causing it to disengage. Then, remove the limiting block 7042 from the interior of the limiting frame 7041. Next, remove the filter plate 705 from the interior of the limiting frame 7041 for replacement. Place the new filter plate 705 into the interior of the limiting frame 7041. Then, put the limiting block 7042 back in. Next, pull the handle again to slide the sliding rod 7044 into the interior of the limiting block 7042. After placing the limiting block 7042 back in its original position, release the handle. The sliding rod 7044 will then be pushed out of the limiting block 7042 by the internally connected spring 7043 and slide into the slot inside the limiting frame 7041.
