Abstract

This utility model relates to the field of garbage disposal technology, specifically a multifunctional garbage disposal device, including a garbage bin and a mounting cover. Four sets of symmetrically distributed casters are fixedly installed under the garbage bin. A first mounting base is fixedly installed inside the garbage bin, and a second mounting base is located below the first mounting base. The first mounting base contains a positioning mechanism, and the second mounting base contains a locking mechanism. The locking mechanism includes a second mounting ring rotatably installed within the second mounting base, and multiple sets of locking plates annularly distributed within the second mounting base.

Description

Technical Field

[0001] This utility model relates to the field of waste cleaning technology, specifically a multifunctional waste cleaning device. Background Technology

[0002] With the acceleration of urbanization and increasingly stringent environmental protection requirements, the demand for intelligent and efficient garbage collection equipment has increased significantly. However, existing equipment still has obvious shortcomings in garbage bag fixing systems. Approximately 78% of sanitation vehicles experience garbage spillage during transportation, which not only affects the urban environment but also causes serious secondary pollution. This situation highlights the necessity and urgency of developing intelligent garbage collection equipment with anti-spillage and self-locking functions, which is of great practical significance for improving the efficiency of urban sanitation operations and reducing carbon emissions.

[0003] In existing garbage collection equipment, garbage bags are usually secured by simple manual tying or by relying on the natural folding of the bag opening. This method can meet basic needs in a static environment, but during transportation or movement, especially on bumpy roads or when the equipment is tilted, the garbage bags are prone to loosening and causing garbage to scatter. This not only affects cleaning efficiency but may also cause secondary pollution. In addition, the method of securing garbage bags in garbage collection equipment often requires operators to repeatedly adjust or re-tie them, increasing the workload and time cost.

[0008] The locking mechanism includes a second mounting ring rotatably mounted within a second mounting base, and multiple sets of locking plates annularly distributed within the second mounting base. Each set of locking plates is rotatably connected to the second mounting base via a second mounting shaft. Multiple sets of second mounting shafts are annularly distributed around the second mounting ring. A second toothed ring is fitted onto the second mounting ring. Second gears are fitted onto each set of second mounting shafts, and the second gears mesh with the second toothed rings. A second handle, perpendicular to the second mounting shaft, is rotatably mounted on the second mounting base. A third bevel gear is fitted onto the second mounting shaft, and a fourth bevel gear is fitted onto the second handle. The third and fourth bevel gears mesh with each other.

[0009] Preferably, the second handle is fitted with two sets of symmetrically distributed ratchet wheels, and the second mounting base is provided with two sets of pawls that mesh with the ratchet wheels. Both sets of pawls are rotatably connected to the second mounting base through rotating rods. Each set of rotating rods is fitted with a third gear. Two sets of racks corresponding to the third gears are slidably installed in the second mounting base. The two sets of racks are respectively meshed with the corresponding third gears. The two sets of racks are fixedly connected by a slide. A slide rod corresponding to the slide is fixedly installed in the second mounting base.

[0010] Preferably, the slide is slidably sleeved with the slide rod, and two sets of symmetrically distributed springs are sleeved on the slide rod. The two ends of the two sets of springs are respectively fixedly connected to the slide and the second mounting base.

[0011] Preferably, a second torsion spring is sleeved on each of the two sets of rotating rods, and the two ends of the second torsion spring are respectively fixedly connected to the corresponding pawl and the second mounting base.

[0012] Preferably, the positioning mechanism includes a first mounting ring rotatably mounted in a first mounting base. The first mounting base has multiple sets of annularly distributed adjusting frames, each set of adjusting frames being rotatably connected to the first mounting base via a first mounting shaft.

The mounting cover is threadedly connected to the trash can. A first handle is rotatably mounted on the first mounting base.

[0013] Preferably, the first handle is perpendicular to the first mounting shaft, a first bevel gear is sleeved on the first mounting shaft, and a second bevel gear is sleeved on the first handle, with the first bevel gear and the second bevel gear meshing together.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a multifunctional garbage cleaning device with the following beneficial effects:

[0017] By rotating the second handle, the fourth bevel gear meshes with the third bevel gear, causing the second mounting shaft to rotate. This, in turn, through the transmission between the second gear and the second gear ring, causes multiple locking plates to rotate synchronously inward, quickly locking the garbage bag opening. After releasing the slide, the synergistic action of the spring and the second torsion spring causes the pawl to automatically engage the ratchet, forming a two-way lock. This ensures the second mounting shaft cannot rotate back, thus firmly securing the garbage bag. This effectively solves the problem of bag opening loosening due to bumps or tilting during transportation, preventing garbage scattering and secondary pollution. It also reduces the workload of repeated manual adjustments, significantly improving ease of use and reliability. The first handle drives the first bevel gear to mesh with the second bevel gear, causing the first mounting shaft to rotate. The linkage between the first gear and the first gear ring causes multiple adjusting frames to move synchronously. The limiting rod then retracts inward, facilitating the flipping and fitting of the garbage bag opening. Releasing the first handle causes the first torsion spring to reset the adjusting frame, and the limiting rod opens the bag opening while maintaining tension. The mounting cover is precisely engaged with the limiting rod via a limiting groove and then threaded in place, forming a double constraint that ensures the garbage bag is firmly fixed between the limiting rod and the limiting groove. This structure not only simplifies the bagging process but also enhances the bag opening's resistance to loosening, significantly reducing the frequency of manual intervention and improving the overall efficiency of the garbage collection equipment.

Detailed Implementation

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Figures 1-6In one embodiment of this utility model, a multifunctional garbage cleaning device includes a garbage bin 1 and a mounting cover 5. Four sets of symmetrically distributed casters 2 are fixedly installed below the garbage bin 1. A first mounting base 3 is fixedly installed inside the garbage bin 1, and a second mounting base 4 is located below the first mounting base 3. A positioning mechanism 7 is provided inside the first mounting base 3, and a locking mechanism 8 is provided inside the second mounting base 4. The locking mechanism 8 includes a second mounting ring 801 rotatably installed inside the second mounting base 4, and multiple sets of locking plates 803 annularly distributed inside the second mounting base 4. All sets of locking plates 803 are rotatably connected to the second mounting base 4 via second mounting shafts 804. Multiple sets of second mounting shafts 804 are annularly distributed around the second mounting ring 801. A second gear ring 802 is sleeved on the second mounting ring 801. Second gears 805 are sleeved on each of the multiple sets of second mounting shafts 804, and the multiple sets of second gears 805 are meshed with the second gear ring 802. A device rotatably mounted on the second mounting base 4 is connected to the second mounting shaft 802. The second handle 806 is vertically distributed. A third bevel gear 807 is sleeved on the second mounting shaft 804. A fourth bevel gear 808 is sleeved on the second handle 806. The third bevel gear 807 and the fourth bevel gear 808 are meshed together. By rotating the second handle 806, the fourth bevel gear 808 is driven to mesh with the third bevel gear 807, which drives the second mounting shaft 804 to rotate. Then, through the transmission of the second gear 805 and the second gear ring 802, multiple locking plates 803 rotate inward synchronously, realizing the rapid locking of the garbage bag opening. After the slide 815 is released, the synergistic action of the spring 817 and the second torsion spring 812 causes the pawl 810 to automatically engage the ratchet 809, forming a two-way lock, ensuring that the second mounting shaft 804 cannot rotate back, thereby firmly fixing the garbage bag. This effectively solves the problem of bag opening loosening caused by bumps or tilting during transportation, avoids garbage scattering and secondary pollution, and reduces the workload of repeated manual adjustments, significantly improving the convenience and reliability of use.

[0028] In this embodiment, reference Figure 5 , Figure 6As shown, two sets of symmetrically distributed ratchet wheels 809 are sleeved on the second handle 806. The second mounting base 4 has two sets of pawls 810 that mesh with the ratchet wheels 809. Both sets of pawls 810 are rotatably connected to the second mounting base 4 via rotating rods 811. Each set of rotating rods 811 is sleeved with a third gear 813. Two sets of racks 814, corresponding to the third gears 813, are slidably installed inside the second mounting base 4. The two sets of racks 814 respectively mesh with their corresponding third gears 813. 3. Engaging connection: The two sets of racks 814 are fixedly connected by a slide 815. A slide rod 816 corresponding to the slide 815 is fixedly installed in the second mounting base 4. The slide 815 and the slide rod 816 are slidably sleeved. Two sets of symmetrically distributed springs 817 are sleeved on the slide rod 816. The two ends of the two sets of springs 817 are fixedly connected to the slide 815 and the second mounting base 4, respectively. A second torsion spring 812 is sleeved on each of the two sets of rotating rods 811. The two ends of the second torsion spring 812 are... The slide 815 is fixedly connected to the corresponding pawl 810 and the second mounting base 4. When it is necessary to fix the garbage bag, the slide 815 is pulled to cooperate with the rack 814 and the third gear 813, so that the two sets of rotating rods 811 drive the pawl 810 to deviate from the corresponding ratchet 809, releasing the lock on the second handle 806. The operator rotates the second handle 806, which drives the fourth bevel gear 808 and the third bevel gear 807 to mesh and drive, so that the second mounting shaft 804 rotates. Due to the meshing action of the second gear 805 and the second gear ring 802, multiple sets of locking plates 803 rotate inward synchronously, clamping the opening of the garbage bag. After locking is completed, the slide 815 is released, the spring 817 pushes the rack 814 to reset, so that the pawl 810 automatically engages with the tooth groove of the ratchet 809 under the action of the second torsion spring 812, forming a two-way self-locking, preventing the second handle 806 from rotating back. This mechanism ensures that the garbage bag will not loosen or fall off when moving or bumping, while reducing manual intervention and improving operating efficiency.

[0029] In this embodiment, reference Figure 3 and Figure 4As shown, the positioning mechanism 7 includes a first mounting ring 701 rotatably mounted within a first mounting base 3. The first mounting base 3 has multiple sets of annularly distributed adjusting brackets 703, each set rotatably connected to the first mounting base 3 via a first mounting shaft 705. The multiple sets of first mounting shafts 705 are symmetrically distributed around the first mounting ring 701. A first toothed ring 702 is sleeved on the first mounting ring 701. A first gear 706 is sleeved on each set of first mounting shafts 705, and the multiple sets of first gears 706 are engaged with the first toothed ring 702. Ring 702 meshes with the device. Limiting rods 704 are fixedly installed on multiple sets of adjusting brackets 703. Limiting grooves 6 are formed inside the mounting cover 5. Multiple sets of limiting rods 704 are movably engaged with the mounting cover 5 through the limiting grooves 6. The mounting cover 5 is threadedly connected to the trash can 1. A first handle 707 is rotatably mounted on the first mounting base 3. The first handle 707 is perpendicular to the first mounting shaft 705. A first bevel gear 708 is sleeved on the first mounting shaft 705. A second bevel gear 709 is sleeved on the first handle 707. The first bevel gear 709... 08 engages with the second bevel gear 709. Multiple sets of first mounting shafts 705 and first handles 707 are fitted with first torsion springs 710. The two ends of the first torsion springs 710 are fixedly connected to the corresponding first mounting shaft 705 or first handle 707 and the first mounting base 3, respectively. During bagging, rotating the first handle 707 causes the first mounting shaft 705 to rotate via the transmission between the first bevel gear 708 and the second bevel gear 709, driving the first gear 706 to engage with the first gear ring 702, thus synchronizing the multiple sets of adjusting brackets 703. When the limit rod 704 is pulled inward, it converges to allow the garbage bag opening to be fitted. After releasing the first handle 707, the first torsion spring 710 drives the adjusting frame 703 to reset. The limit rod 704 then expands the garbage bag opening outward and remains taut. Subsequently, the limit groove 6 of the mounting cover 5 is aligned with the limit rod 704 and pressed down. The mounting cover 5 is then rotated to lock it with the threads of the garbage can 1, so that the garbage bag opening is firmly locked between the limit rod 704 and the limit groove 6. This design enables the garbage bag to be quickly installed and stably fixed, improving sealing and anti-fall-off performance.

[0030] In this embodiment, when it is necessary to secure the garbage bag, pulling the slide 815 in conjunction with the rack 814 and the third gear 813 causes the two sets of rotating rods 811 to drive the pawl 810 to deviate from the corresponding ratchet 809, releasing the lock on the second handle 806. The operator rotates the second handle 806, driving the fourth bevel gear 808 to mesh with the third bevel gear 807, causing the second mounting shaft 804 to rotate. Due to the meshing action of the second gear 805 and the second gear ring 802, multiple sets of locking plates 803 rotate inward synchronously, clamping the opening of the garbage bag. After locking is completed, the slide 815 is released, and the spring 817 pushes the rack 814 to reset, causing the pawl 810 to automatically engage with the ratchet 809 tooth groove under the action of the second torsion spring 812, forming a two-way self-locking mechanism to prevent the second handle 806 from rotating back. This mechanism ensures that the garbage bag will not rotate when moving or bumping. The design facilitates quick and easy bag installation, reduces manual intervention, and improves operational efficiency. When bagging, rotating the first handle 707 causes the first mounting shaft 705 to rotate via the transmission of the first bevel gear 708 and the second bevel gear 709. This drives the first gear 706 to mesh with the first gear ring 702, causing multiple sets of adjusting brackets 703 to retract inwards simultaneously. The limiting rod 704 then converges to allow the garbage bag opening to be fitted. After releasing the first handle 707, the first torsion spring 710 drives the adjusting brackets 703 to reset, and the limiting rod 704 expands outwards and remains taut. Then, the limiting groove 6 of the mounting cover 5 is aligned with the limiting rod 704 and pressed down, and the mounting cover 5 is rotated to lock it threaded into the garbage bin 1, ensuring the garbage bag opening is securely locked between the limiting rod 704 and the limiting groove 6. This design achieves rapid installation and stable fixation of the garbage bag, improving sealing and anti-fall-off performance.
