The Double-box Underground Garbage Compactor is a type of waste disposal facility that integrates the unloading, compression and storage functions of the waste compactor and is placed entirely underground. It usually adopts a one-machine-two-box configuration, that is, one compression device is equipped with two garbage containers, and the container replacement is achieved through a moving box mechanism.

Product Advantage
One machine, two boxes, continuous operation without interruption:
Alternate working mode. Once one box is filled, the moving box mechanism quickly switches to another empty box to continue compression. There is no need to stop the machine and wait for the transfer vehicle to transport the full box.
Parallel transfer and compression. While the garbage transfer vehicle is transporting the full box, the compression main unit can compress the other box of garbage, significantly improving the overall processing efficiency. The cycle time for compression operations is short.
Maximized equipment utilization. One machine, multiple boxes, flexible configuration, suitable for different garbage volume processing needs, especially suitable for areas with a large amount of garbage generation.
Compression and reduction: By applying strong pressure to the garbage, its volume is significantly reduced. The compression ratio is usually high, which can greatly decrease the space occupied by the garbage. This means that within the same storage space, more garbage can be accommodated, reducing the frequency and cost of garbage removal.
Facilitates transportation: After compression, the garbage becomes more compact and denser, making it easier to transport using garbage collection vehicles for centralized disposal. It reduces the scattering and flying of garbage during transportation, and minimizes the pollution to the surrounding environment along the transportation route.
Health and Environmental Protection: The underground sealed structure effectively isolates the garbage from the external environment, reducing the emission of garbage odors and the breeding of mosquitoes and flies, and minimizing pollution to the surrounding air and soil. At the same time, during the compression process, wastewater in the garbage can also be collected and treated, further protecting the environment.

Product Uses
The core working principle of the double-box underground garbage compactor is the "one machine with two boxes" configuration. Through the cyclic process of compression, box movement and transfer, continuous operation of garbage compression treatment is achieved.
Loading and compression stage
The garbage collection vehicle pours scattered garbage into the loading port on the ground of the equipment. The flipping device below the loading port will smoothly send the garbage into the compression chamber underground.
The hydraulic system drives the compression cylinder, pushing the compression head to horizontally squeeze the garbage in the compression chamber. During the squeezing process, the wastewater will flow through the drainage hole at the bottom of the compression chamber into the sewage collection tank in the underground pit, and then be discharged into the urban sewage network by the sewage pump to prevent sewage from seeping and polluting the soil.
After each compression is completed, the compression head returns to its original position. A new round of garbage is then loaded and compressed again. This cycle repeats until one of the garbage bins is filled.
The stage of switching between full and empty containers
When the first garbage container becomes full, the electronic control system sends a signal, activating the moving mechanism. This mechanism then moves the full container of garbage away from the docking position of the compression machine. At the same time, it precisely pushes the pre-positioned empty garbage container to the docking position. The entire switching process does not require a stop, ensuring uninterrupted compression operations.
After the switching is completed, the compression machine immediately continues to compress garbage into the empty container, ensuring the efficiency of garbage disposal.
Translocation and Re-positioning Phase
The detachable garbage transfer vehicle of the carriage enters the operation area. Through the lifting or telescopic mechanism attached to the vehicle, the full garbage bins are lifted and transported to the garbage disposal plant for subsequent processing.
After the full bins are transported away, the transfer vehicle will return the empty garbage bins to the standby position of the underground garbage station, waiting for the next switch, thus forming a closed-loop operation process of "compression - full bin - transfer - empty bin replenishment".
Run Process
when the box body is full of garbage collection system will be prompted to start the lifting system,the equipment will be raised to the ground level,and then the compressed box body will be compressed with the compartments of the removable garbage truck to transport to the garbage disposal center; after the dumping of the garbage,the compressed box body will be transported back to the elevating platform,and then the platform as a whole fall into the ground.

Application scenarios
Double-box Underground Garbage Compactor with its core features of small footprint, good environmental performance, and high continuous operation efficiency, is suitable for various scenarios where the amount of garbage generated is moderate to high and where there are requirements for the environment and space.
Urban Residential Communities
These areas have a high population density, with a stable and concentrated amount of domestic waste generated. At the same time, there are high requirements for odor, noise, and the aesthetic appeal of the landscape. The underground installation mode of equipment does not occupy the ground green space or parking space. The sealed compression can effectively isolate the odor and prevent the breeding of mosquitoes and flies. The design of alternate operation of two bins can cope with the peak garbage disposal periods in the morning and evening, preventing garbage accumulation from disturbing residents. It is the preferred equipment for the environmental sanitation renovation of urban communities.
Public services and commercial facilities
These include schools, hospitals, large supermarkets, office buildings, etc. These places have a large number of people and complex garbage compositions, and have strict requirements for hygiene standards. The sealed structure of the equipment can meet the hygiene and epidemic prevention needs of hospitals, and the continuous operation capability can quickly handle the garbage during peak hours, while reducing the frequency of manual contact with garbage and improving operational safety.
Cultural and Tourism Leisure Area
This area includes scenic spots, parks, ancient towns, and cultural tourism towns. This type of area focuses on the aesthetic appeal of the landscape as its core competitiveness. Traditional ground garbage stations would damage the overall appearance. However, the double-box underground garbage compactor only exposes the feeding port and can be integrated with the surrounding landscape design. At the same time, the equipment has a good noise isolation effect, which will not affect the tourists' enjoyment of the visit. The sealed compression can also prevent the spread of garbage odors and ensure the environmental quality of the scenic area.
Townships and New Rural Areas for Construction
As the rural revitalization initiative progresses, the environmental protection standards for sanitation facilities in townships and new rural areas have gradually improved. These areas generate less waste compared to large cities, but the waste distribution is relatively scattered. The construction cost of the double-box underground garbage compactor is lower than that of traditional garbage transfer stations, and it does not require complex civil engineering; the compression and reduction function can significantly reduce the frequency of garbage transportation, lowering the transportation costs for township sanitation and meeting the needs of township garbage disposal.
Industrial parks and industrial zones
Applicable to industrial parks, logistics parks, science and technology parks, etc. These areas generate mixed garbage such as industrial scraps and operation waste. The garbage has a large volume and high transportation costs. The high compression ratio of the equipment can significantly reduce the volume of the garbage. The double-box continuous operation can match the garbage collection rhythm of the park, and at the same time, the underground installation does not occupy the production or storage land of the park, balancing practicality and space utilization.
