[0026] 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.

[0027] Example 1:

[0028] Please see Figures 1 to 4 As shown, the municipal solid waste compression and sealing collection device includes:

[0029] Garbage compression box 1;

[0030] A compression mechanism 2 is installed in the middle of one end of the garbage compression box 1, a collection mechanism 3 is installed at the bottom of the garbage compression box 1, and a feed hopper 4 is installed on one side of the top of the garbage compression box 1.

[0031] The compression mechanism 2 includes a compression plate 21, a cleaning frame 22, a hydraulic cylinder 23, and crushing blocks 24. The cleaning frame 22 is installed on the outer surface of the compression plate 21. There are two hydraulic cylinders 23, and both hydraulic cylinders 23 are installed in the middle of one end of the compression plate 21. Both hydraulic cylinders 23 are installed on one side wall of the garbage compression box 1. There are multiple crushing blocks 24, and multiple crushing blocks 24 are installed at the other end of the compression plate 21.

[0032] Depend on Figures 1 to 3It can be seen that a reinforcing frame 5 is installed at the other end of the garbage compression box 1. Limiting grooves 6 are opened on both sides of the inner wall of the reinforcing frame 5. A sealing plate 7 is slidably installed between the two limiting grooves 6. A pull ring 8 is installed at the top center of the sealing plate 7.

[0033] The cleaning frame 22 includes a fixed frame 221, a cleaning brush 222, a cleaning scraper ring 223, and a sealing ring 224. The fixed frame 221 is installed on the outer surface of the compression plate 21, the cleaning brush 222 is installed on one side of the outer surface of the fixed frame 221, the cleaning scraper ring 223 is installed in the middle of the outer surface of the fixed frame 221, and the sealing ring 224 is installed on the other side of the outer surface of the fixed frame 221.

[0034] As can be seen from the above, during use, household waste is first fed into the waste compression box 1 through the feed hopper 4. Then, the device is started, and the two hydraulic cylinders 23 work synchronously to provide power to push the compression plate 21 towards the waste. This allows the multiple crushed blocks 24 on the compression plate 21 to first contact the waste and perform preliminary crushing, loosening the waste structure for subsequent compression. As the compression plate 21 continues to advance, the waste is gradually compressed, and its volume is significantly reduced. This can significantly increase the waste loading capacity, reduce the number of collections, and lower transportation costs. At the same time, the cleaning frame 22 installed on the outer surface of the compression plate 21 moves synchronously with the compression plate 21, and the cleaning brush 222 first brushes away the waste adhering to the surface. Garbage residue on the inner wall of the garbage compression box 1 is removed by a scraper ring 223 to further remove stubborn residue and ensure the inner wall is clean. Finally, a sealing ring 224 ensures the sealing of the compression process, preventing garbage leakage and odor emission. This design can clean the garbage residue attached to the inner wall of the box in time, avoid the residue from causing additional wear to the compression plate 21 and the inner wall of the box, effectively extend the service life of the equipment, reduce the difficulty of cleaning and maintenance, and provide a cleaner and more efficient environment for garbage disposal. After compression is completed, the sealing plate 7 can be pulled upward by pulling the pull ring 8 to open the discharge port of the garbage compression box 1. At this time, the hydraulic cylinder 23 extends to push the compressed garbage block out of the garbage compression box 1.

[0035] For details, please refer to Figures 1 to 3 As shown, the fixing frame 221, cleaning brush 222, cleaning scraper ring 223 and sealing ring 224 are all set in a U-shape structure, and the outer surfaces of the cleaning brush 222, cleaning scraper ring 223 and sealing ring 224 are in contact with the inner wall of the garbage compression box 1.

[0036] As can be seen from the above, the U-shaped structure helps these components to be installed more tightly and securely on the outer surface of the compression plate 21, forming a good fit with the inner wall of the garbage compression box 1, providing a structural basis for subsequent cleaning, sealing and other functions. These components can achieve specific functions such as cleaning garbage, scraping off residues and sealing by contacting the inner wall of the garbage compression box 1.

[0037] Example 2:

[0038] refer to Figure 4 As shown, the collection mechanism 3 includes a collection box 31, a guide pipe 32, a guide plate 33, and a drain pipe 34. The collection box 31 is installed at the bottom of the garbage compression box 1. Multiple guide pipes 32 are provided, and all multiple guide pipes 32 are installed on one side of the top of the collection box 31. The top of the multiple guide pipes 32 penetrates the bottom wall of the garbage compression box 1. The guide plate 33 is installed on the bottom wall of the collection box 31. The drain pipe 34 is installed on the lower side of one end of the collection box 31.

[0039] As can be seen from the above, during the garbage compression process, the sewage contained in the garbage will flow into the collection box 31 through multiple guide pipes 32 due to gravity and compression pressure. The guide pipes 32 are designed with a tapered structure that is narrow at the top and wide at the bottom, which facilitates the smooth flow of liquid. When the sewage enters the collection box 31, the inclined surface at the top of the guide plate 33 will guide the sewage to the area near the drain pipe 34. Finally, the sewage will be discharged out of the device through the drain pipe 34 installed on the lower side of one end of the collection box 31, which facilitates the rapid discharge of sewage and achieves effective separation and collection of garbage and sewage. This avoids sewage accumulation and pollution of the garbage compression environment. This design not only prevents sewage from accumulating at the garbage collection point and emitting odors, improving the surrounding environmental sanitation, but also provides convenient conditions for subsequent garbage classification and recycling, which meets the requirements of environmental protection and sustainable development.

[0040] Preferred, Reference Figure 4 As shown, the guide tube 32 is a tapered structure that is narrow at the top and wide at the bottom, and the top surface of the guide plate 33 is an inclined surface.

[0041] As can be seen from the above, some liquid will be generated during the garbage compression process. The conical structure with a narrow top and a wide bottom can utilize the gravity of the liquid to make it flow more smoothly down the guide pipe 32 and into the collection box 31. The inclined surface of the guide plate 33 can guide the liquid flowing into the collection box 31 to the vicinity of the drain pipe 34, making it easier for the liquid to gather and be discharged, thus improving drainage efficiency.

[0042] Application example:

[0043] This design is applied to places that generate large amounts of domestic waste, such as urban streets, communities, commercial areas, schools, and hospitals. Taking urban communities as an example, a large amount of domestic waste, including kitchen waste, recyclable waste, hazardous waste, and other waste, is generated daily within the community. Traditional collection methods easily lead to problems such as scattered waste, odors, and sewage, affecting the community environment and residents' lives. This device can effectively solve these problems. Its working principle is as follows: The compression mechanism 2 pushes the compression plate 21 through the hydraulic cylinder 23, using the crushing blocks 24 to initially crush the waste and compress its volume. At the same time, the cleaning frame 22 installed on the outer surface of the compression plate 21 cleans the residue on the inner wall of the container during movement. The wastewater generated by the garbage compression is collected in a tapered guide pipe 32 (narrower at the top and wider at the bottom) to the bottom collection box 31. The guide plate 33 with an inclined surface guides the wastewater to the drain pipe 34 for discharge, thus separating the garbage from the wastewater. This device has significant environmental benefits: it greatly reduces the volume of garbage by compression, improves collection efficiency and reduces transportation costs; timely collection and discharge of wastewater prevents the accumulation of odors and improves community sanitation; the cleaning rack 22 reduces wear and tear on the equipment caused by residue and extends its service life; the compressed garbage is easier to classify and process, promotes the resource utilization of recyclables, improves environmental quality and meets the needs of sustainable development.
