Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically, it relates to a waste sorting device. Background Technology

[0002] Solid waste refers to solids that are generated during production, daily life and other activities and have lost their original utilization value, or solids that have not lost their utilization value but have been discarded or abandoned. Solid waste treatment is a process of reducing its volume and accelerating its natural purification through physical means (such as crushing, compression, drying, evaporation, incineration, etc.) or biochemical processes (such as oxidation, digestion and decomposition, absorption, etc.) and chemical processes such as pyrolysis and gasification.

[0003] In waste treatment scenarios, sorting equipment often needs to handle various types and sizes of waste. However, existing equipment has significant shortcomings in multi-stage screening, especially when the waste particles are complex in shape or diverse in material. Traditional equipment struggles to accurately screen them. Furthermore, waste can easily clog the screening structure during screening, or insufficient screening can lead to reduced efficiency in subsequent processing. Users need to intervene frequently, which not only reduces work efficiency but also significantly increases labor intensity. Therefore, there is a need for a device that can efficiently complete multi-stage screening and adapt to diverse waste treatment needs to improve the efficiency and quality of waste sorting.

[0004] During the waste collection process after treatment, users often need to frequently disassemble or replace waste collection containers. However, traditional designs lack structures for quick fixing and disassembly, making the replacement process cumbersome and time-consuming. During long-term use, the collection containers may become loose or shift due to vibration, leading to waste leakage or even requiring machine shutdown for adjustment. This causes great inconvenience to waste treatment operations. Therefore, there is an urgent need for a design scheme that can easily install, replace, and stabilize collection containers to improve the ease of operation and efficiency of the equipment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a waste sorting device to solve the technical problem mentioned in the background art that the waste collection container needs to be frequently disassembled or replaced, but the traditional design lacks a structure for quick fixing and disassembly, making the replacement process cumbersome and time-consuming.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a waste sorting device, comprising a support base, on which a screening mechanism is provided. The screening mechanism includes a support column, a collection box, a sorting bin, a sieve plate, a motor, a central rod, a mounting sleeve, and a push plate. The support column is positioned above the support base. Multiple sets of collection boxes are mounted on the support column via a quick-fixing mechanism. The sorting bin is mounted at the top of the support column. Multiple sets of sieve plates are mounted on the bottom surface of the sorting bin. The motor is mounted at the top of the support column. The central rod is mounted at the motor output end. The mounting sleeve is mounted on the central rod. Multiple sets of push plates are mounted on the outer wall of the mounting sleeve. The quick-fixing mechanism includes a fixed sleeve, a locking block, a rocker arm, a locking rod, a locking groove, a push sleeve, and rollers. The fixed sleeve is mounted at the top of the support base. Multiple sets of locking blocks are rotatably mounted on the fixed sleeve. The rocker arm is mounted on the outer side of the multiple sets of locking blocks. The locking rod is mounted on the inner side of the collection box. The locking groove is located on the locking rod. The push sleeve slides on the outer side of the fixed sleeve. Multiple sets of rollers are mounted on the push sleeve.

[0009] The present invention is further configured such that the sieve holes on the multiple sets of sieve plates are respectively configured with various shapes. By configuring sieve holes of various shapes, the classification needs of diverse wastes can be met, the screening accuracy can be avoided due to differences in waste form, and the comprehensiveness of the screening effect can be improved.

[0010] The present invention is further configured such that the outer wall of the support column is provided with a positioning groove, and multiple sets of positioning grooves are provided. Multiple sets of the locking rods are engaged in multiple sets of positioning grooves. The cooperative design of multiple sets of positioning grooves and locking rods ensures the stability of the collection box during installation. Even when the equipment vibrates, it can prevent the waste from leaking out due to the collection box becoming loose.

[0011] The present invention is further provided that each of the multiple sets of card blocks is connected to the top surface of the card block and the fixing sleeve with a tension spring. The design of the tension spring enables the card block to have a self-resetting ability, which makes the operation simple and improves the locking security. At the same time, it avoids the trouble of manual adjustment and improves the operating efficiency of the device.

[0012] The present invention is further configured such that a transmission sleeve is installed on the bottom surface of the push sleeve, a rotating sleeve is rotatably installed on the bottom end of the fixed sleeve, a threaded sleeve is installed on the outer wall of the rotating sleeve, and the inner wall of the threaded sleeve and the outer wall of the transmission sleeve are threadedly connected. The threaded connection makes the operation of the push sleeve and the fixed sleeve more stable, and can achieve efficient and quick disassembly and assembly through rotation, while avoiding jamming and misoperation during assembly and disassembly.

[0013] The present invention is further configured such that multiple sets of rollers are rotatably mounted on the push sleeve, and multiple sets of rocker plates are provided with a certain curvature. The roller design reduces the friction when the push sleeve slides, improving the flexibility of the push sleeve operation. The curvature design of the rocker plates optimizes the force transmission process, making the operation easier and smoother.

[0014] The present invention is further configured such that a linkage mechanism is provided inside the sorting bin, the linkage mechanism including a linkage shaft, a scraper, a gear and a gear ring. Multiple sets of linkage shafts are provided and are rotatably installed on the outer ends of multiple sets of push plates. Multiple sets of scrapers are provided and are installed on the outer walls of multiple sets of linkage shafts. The gears are installed on the top ends of multiple sets of linkage shafts. The gear ring is installed inside the sorting bin and meshes with multiple sets of gears, which can smoothly and efficiently clean the inner wall of the sorting bin and avoid the problem of incomplete sorting caused by waste adhesion.

[0015] The present invention is further configured such that all of the multiple sets of scrapers are made of hard rubber plates, and the hard rubber material makes the scrapers both flexible and durable.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a waste sorting device, which has the following beneficial effects:

[0018] 1. The design of the screening mechanism makes waste sorting more efficient and accurate. The screen plate can achieve multi-level classification according to the size and shape of the waste through different screen hole shapes, while the push plate further improves the screening efficiency and ensures that waste does not accumulate on the screen plate surface. The motor drives the rotation of the central rod and the mounting sleeve, making the screening process smoother and more continuous, avoiding the clogging problem in traditional screening equipment, and significantly improving the efficiency and reliability of waste screening.

[0019] 2. The quick-release mechanism significantly improves the efficiency of installing and removing the collection box. The combination of the fixing sleeve, the locking block, and the locking rod ensures the stability of the collection box during operation. Even under high load, the collection box will not shift or loosen. Through the sliding operation of the push sleeve and the roller, the user can easily release the locking block and the locking rod to quickly replace or clean the collection box. The arc design of the rocker further optimizes the operating feel and reduces the labor intensity during use.

[0020] 3. The linkage mechanism, through the design of the linkage shaft and scraper, improves the uniformity of waste sorting within the sorting bins. The rotation of the linkage shaft, combined with the meshing of gears and gear rings, allows the scraper to smoothly and efficiently clean the inner wall of the sorting bins, avoiding the problem of incomplete sorting caused by waste adhesion. The scraper's hard rubber material design gives it high wear resistance and flexibility, allowing for thorough cleaning of the bin walls without damaging the equipment. The overall design of the linkage mechanism not only improves the uniformity of waste sorting but also reduces the frequency of equipment blockage and maintenance, significantly improving the equipment's operating efficiency and stability.

[0030] Please see Figures 1-5A waste sorting device includes a support base 1, on which a screening mechanism is mounted. The screening mechanism includes a support column 2, a collection box 3, a sorting bin 4, a sieve plate 5, a motor 6, a central rod 7, a mounting sleeve 8, and a push plate 9. The support column 2 is positioned above the support base 1. Multiple sets of collection boxes 3 are mounted on the support column 2 via quick-release mechanisms. The sorting bin 4 is mounted at the top of the support column 2. Multiple sets of sieve plates 5 are mounted on the bottom surface of the sorting bin 4. The motor 6 is mounted at the top of the support column 2. The central rod 7 is mounted at the output end of the motor 6. The mounting sleeve 8 is used to install... On the central rod 7, the push plate 9 is provided with multiple sets installed on the outer wall of the mounting sleeve 8. The quick-fixing mechanism includes a fixed sleeve 10, a locking block 11, a rocker plate 12, a locking rod 13, a locking groove 14, a push sleeve 15, and rollers 16. The fixed sleeve 10 is installed on the top of the support base 1. The locking block 11 is provided with multiple sets rotatably installed on the fixed sleeve 10. The rocker plate 12 is installed on the outside of the multiple sets of locking blocks 11. The locking rod 13 is installed on the inside of the collection box 3. The locking groove 14 is provided on the locking rod 13. The push sleeve 15 slides on the outside of the fixed sleeve 10. The rollers 16 are provided with multiple sets installed on the push sleeve 15.

[0031] The sieve holes on the multiple sets of sieve plates 5 are set with various shapes.

[0032] The outer wall of the support column 2 is provided with a positioning groove 17. Multiple sets of positioning grooves 17 are provided, and multiple sets of locking rods 13 are engaged in multiple sets of positioning grooves 17.

[0033] Each of the multiple sets of locking blocks 11 has a tension spring 18 connecting its top surface to the fixing sleeve 10.

[0034] A transmission sleeve 19 is installed on the bottom surface of the push sleeve 15, and a rotating sleeve 20 is rotatably installed on the bottom end of the fixed sleeve 10. A threaded sleeve 21 is installed on the outer wall of the rotating sleeve 20, and the inner wall of the threaded sleeve 21 is threadedly connected to the outer wall of the transmission sleeve 19.

[0035] Multiple sets of rollers 16 are rotatably mounted on push sleeves 15, and multiple sets of rocker plates 12 are all provided with a certain curvature.

[0036] In this embodiment, the waste in the sorting bin 4 is initially screened by the different screen hole sizes of the sieve plate 5. Smaller waste particles or lightweight materials will pass through the smaller screen holes, while larger or irregular waste will be retained on the sieve plate 5. The screening process is driven by the motor 6 to rotate the central rod 7. The rotation of the central rod 7 drives the mounting sleeve 8 to rotate, while the push plate 9 on the mounting sleeve 8 simultaneously pushes and agitates the waste on the surface of the sieve plate 5, ensuring that the waste can fully contact the sieve plate 5 and effectively complete the screening. The multiple sets of sieve plates 5 with various screen hole shapes can meet the screening needs of waste of different shapes, achieving multi-level and diversified screening effects. The collection box 3 is inserted into the positioning groove 17 on the outer wall of the support column 2 by the clamping rod 13, thereby achieving stable positioning. Then, the rotating sleeve 20 is rotated to drive the screw sleeve 21 to rotate. The screw sleeve 21 is threadedly connected to the transmission sleeve 19. This causes the transmission sleeve 19 to push the push sleeve 15 to move. The push sleeve 15 drives multiple sets of rollers 16 to abut against the bottom surface of the rocker plate 12, thereby pushing the locking block 11 to engage in the slot 14 and fixing the locking rod 13. At the same time, the movement of the locking block 11 stretches the tension spring 18, completing the fixed installation of the collection box 3 and preventing the collection box 3 from loosening due to vibration or other external forces. When it is necessary to disassemble the collection box 3, the rotating sleeve 20 is rotated in the opposite direction to drive the threaded sleeve 21 to engage with the transmission sleeve 19. At the same time, the rollers 16 are driven to release the push on the rocker plate 12. The elastic reset of the tension spring 18 pulls the locking block 11 to reset, causing the locking block 11 to disengage from the slot 14 of the locking rod 13, thereby releasing the fixing of the collection box 3 and easily removing the collection box 3. Through this structural design, the quick-fix mechanism of the device achieves efficient and quick operation, which is convenient for cleaning and replacement during the waste collection process.

[0037] Please see Figure 2 As one implementation of the linkage mechanism: a linkage mechanism is provided inside the sorting bin 4. The linkage mechanism includes a linkage shaft 22, a scraper 23, a gear 24, and a gear ring 25. Multiple sets of linkage shafts 22 are provided and are rotatably installed on the outer ends of multiple sets of push plates 9. Multiple sets of scrapers 23 are provided and are installed on the outer walls of multiple sets of linkage shafts 22. The gears 24 are installed on the top ends of multiple sets of linkage shafts 22. The gear ring 25 is installed inside the sorting bin 4 and meshes with multiple sets of gears 24.

[0038] All sets of scrapers 23 are made of hard rubber plates.

[0039] More specifically, while the motor 6 drives the central rod 7 and the push plate 9 to rotate, it also drives the gear 24 installed at the top of the linkage shaft 22 to mesh with the gear ring 25, so that the gear 24 drives the linkage shaft 22 to rotate. The linkage shaft 22 drives multiple sets of scrapers 23 to rotate simultaneously. The rotation of the linkage shaft 22 drives the scrapers 23 to clean the inner wall of the sorting bin 4, preventing waste from adhering to or accumulating on the wall of the sorting bin 4 during the screening process.

[0040] In summary, during the use or operation of the overall equipment: waste in the sorting bin 4 is initially screened through the different screen hole sizes of the screen plate 5. Smaller waste particles or lightweight materials will pass through the smaller screen holes, while larger or irregular waste will be retained on the screen plate 5. The screening process is driven by the motor 6 to rotate the central rod 7. The rotation of the central rod 7 drives the mounting sleeve 8 to rotate, while the push plate 9 on the mounting sleeve 8 simultaneously pushes and agitates the waste on the surface of the screen plate 5, ensuring that the waste can fully contact the screen plate 5 and effectively complete the screening. The multiple screen holes of the multiple sets of screen plates 5 can meet the screening needs of waste of different shapes, achieving multi-level and diversified screening effects. The collection box 3 is inserted into the positioning groove 17 on the outer wall of the support column 2 through the clamping rod 13, thereby achieving stable positioning. Then, the rotating sleeve 20 is rotated to drive the screw sleeve 21 to rotate. The screw sleeve 21 is threaded with the transmission sleeve 19. The connection and cooperation allow the transmission sleeve 19 to push the push sleeve 15 to move. The push sleeve 15 drives multiple sets of rollers 16 to abut against the bottom surface of the rocker plate 12, thereby pushing the locking block 11 to engage in the slot 14 and fixing the locking rod 13. At the same time, the movement of the locking block 11 stretches the tension spring 18, completing the fixed installation of the collection box 3 and preventing the collection box 3 from loosening due to vibration or other external forces. When it is necessary to disassemble the collection box 3, the rotating sleeve 20 is rotated in the opposite direction to drive the threaded sleeve 21 to engage with the transmission sleeve 19. At the same time, the rollers 16 are driven to release the push on the rocker plate 12. The elastic reset of the tension spring 18 pulls the locking block 11 to reset, causing the locking block 11 to disengage from the slot 14 of the locking rod 13, thereby releasing the fixation of the collection box 3 and easily removing the collection box 3. Through this structural design, the quick-fix mechanism of the device achieves efficient and quick operation, facilitating cleaning and replacement during the waste collection process.

[0041] While the motor 6 drives the central rod 7 and the push plate 9 to rotate, it also drives the gear 24 installed at the top of the linkage shaft 22 to mesh with the gear ring 25, so that the gear 24 drives the linkage shaft 22 to rotate. The linkage shaft 22 drives multiple sets of scrapers 23 to rotate simultaneously. The rotation of the linkage shaft 22 drives the scrapers 23 to clean the inner wall of the sorting bin 4, preventing waste from adhering to or accumulating on the wall of the sorting bin 4 during the screening process.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
