The Underground Hydraulic Trash Compactor is an innovative waste treatment equipment that integrates the compression unit and the storage box or its main components underground. It utilizes a hydraulic system to provide powerful compression force, compacting and reducing loose household waste, achieving sealed, reduced, and harmless collection and transportation of garbage.
Compared to traditional ground-based garbage collection facilities, the core advantage of the Underground Hydraulic Trash Compactor lies in its concealed design. Only the loading port and operation platform are retained on the ground, significantly enhancing environmental friendliness and space utilization. Its compression ratio can reach 1:3 to 1:4, reducing the volume of garbage by 50% to 70%, significantly lowering transportation costs and carbon emissions.
Core ClassificationUnderground sealed box: Garbage storage and compression space
Made of high-strength structural steel, it is fully sealed and welded, resistant to corrosion and leakage. It is divided into three parts: hopper, feeding bin, and compression bin.
Hydraulic compression mechanism: Provides compression power
It includes the compression push plate, main hydraulic cylinder, and guiding device. The surface of the push plate is treated for wear resistance. The hydraulic cylinder uses imported seals, ensuring a long service life.
Lifting system: Box lifting and transfer docking
It is divided into four-column lifting type, scissor type, and vertical lifting type. It is equipped with a safety locking device to ensure a stable and safe lifting process.
Hydraulic power unit: The core power source of the hydraulic system
Composed of a motor, high-pressure oil pump, oil tank, filter, cooler, etc., it is highly efficient and energy-saving.
Electrical control system: Automatic control of equipment operation
Equipped with PLC programmable controller, touch screen operation interface, and remote control device, supporting fault self-diagnosis and alarm functions
Wastewater collection and treatment system: Treating the leachate generated by compression
Water collection tanks, sewage pipelines and sewage pumps are installed in the pit. The leachate is directly discharged into the urban sewage network to prevent secondary pollution.
Safety protection system: Ensuring the safety of personnel and equipment
It includes safety grilles at the feeding ports, operation interlock devices, overload protection, limit switches, emergency stop buttons, etc.
Product AdvantageFully sealed design: The underground box is completely sealed, effectively isolating garbage odors, leachate and mosquitoes, and eliminating secondary pollution.
Visual beautification: Only the feeding port is left on the ground, which can blend in with the surrounding environment, and even be covered with greenery or used as a parking lot, enhancing the urban landscape.
Noise control: Underground installation significantly reduces equipment operation noise, meeting the noise standards for residential areas.
Significant reduction in volume: High compression ratio, reducing the frequency of garbage transportation by 50%-70%, and lowering transportation costs.
Continuous operation: The double-box design enables uninterrupted compression, improving processing efficiency, and suitable for high-load scenarios.
Low energy consumption: Using a constant power variable pump hydraulic system, the energy distribution is reasonable, and it is 20%-30% more energy-efficient than traditional ground compressors.
Remote operation: Equipped with remote control, operators do not need to be close to the garbage, avoiding contact with pollution.
Multiple safety protections: Operating interlock, overload protection, emergency stop and other devices ensure the safety of personnel and equipment.
Maintenance convenience: Key components can be raised to the ground for maintenance, without the need for underground operations, reducing maintenance difficulty and risk.
Installation flexibility: Can be installed indoors or outdoors, with low requirements for the site, and the floor area is only 15-20 square meters.
Garbage compatibility: Can handle mixed domestic waste, kitchen waste, packaging waste and other types, with wide adaptability.
Climate adaptability: Underground installation is not affected by adverse weather conditions such as rain, snow, high temperatures, and operates stably throughout the year.

Working PrincipleThe Underground Hydraulic Trash Compactor follows a four-step closed-loop process of "collection - compression - storage - transportation", all controlled automatically throughout the process:
Garbage disposal stage: Loose garbage is poured into the underground sealed container through the ground loading port.
Automatic compression stage: The hydraulic system drives the compression push plate to perform multiple horizontal compressions on the garbage, until the preset density is reached.
Emptying detection stage: The pressure sensor or position sensor is used to determine whether the container is full, and the compression stops automatically and a prompt is issued.
Lifting and transportation stage: The lifting mechanism lifts the container filled with compressed garbage to the ground, and precisely aligns it with the garbage grab arm vehicle. The lifting device lifts the equipment and moves it away.
Reset preparation stage: The container falls back to its original position underground, and is automatically cleaned and prepared for the next garbage reception cycle.

Main Types and CategoriesBased on different dimensions, they can be classified into various types, which are suitable for different application scenarios:
Classified by compression direction
Horizontal compression type: The compression push plate moves horizontally, suitable for large transfer stations, with high processing efficiency and stable compression ratio
Vertical compression type: The compression head moves from top to bottom, suitable for small stations, with less floor space and a more compact structure
Classified by the number of box bodies:
Single-box type: One compression device is equipped with one box body. The structure is simple, the cost is low, and it is suitable for small communities or areas with low garbage volume.
Double-box type: One compression device is equipped with two box bodies. Through the box shifting mechanism, it works alternately and operates continuously without interruption. There is no need to stop for transfer, making it suitable for areas with high garbage volume.
Classification by lifting method
Four-column lifting type: Guided by four upright columns, the lifting is smooth and stable, with strong load-bearing capacity, suitable for large containers
Scissor-type lifting: Compact structure, moderate lifting height, suitable for small and medium-sized containers
Swinging-type lifting: The container can rotate around an axis, facilitating garbage dumping, suitable for installation in special terrains
Classification by Automation Degree
Semi-automatic type: Requires manual operation of buttons to start compression and lifting, with lower cost
Fully automatic type: Equipped with sensing systems, automatically identifies garbage and initiates compression. An alarm is triggered when the container is full.
SolutionHigh initial investment: Long-term operation can reduce transportation and labor costs. The investment payback period is usually 2-3 years.
High requirements for pit construction: Select a professional construction team, ensure waterproofing, anti-corrosion and foundation treatment to ensure service life.
Limited maintenance space: Choose models that can be lifted to the ground as a whole, with modular design for key components for easy replacement.
Not suitable for handling special waste: Prohibit the disposal of construction waste, large metals, flammable and explosive items. Equip with garbage classification guidance signs.
The Underground Hydraulic Trash Compactor is installed underground in a concealed manner. The main body of the machine is placed underground, which can greatly save floor space and optimize the surrounding environmental landscape. It uses hydraulic power to achieve strong compaction and reduction of garbage volume, effectively reducing the volume of garbage, reducing the number of transfers and transportation costs. The fully enclosed structure of the equipment can isolate garbage odors, centrally handle leachate, eliminate mosquito breeding and secondary pollution, and at the same time, the underground layout reduces operating noise. Combined with an intelligent electrical control system, the operation is simple, the safety protection is complete, it is environmentally friendly, economical and practical, and is widely applicable in places such as residential areas, commercial districts, and scenic spots, helping to achieve harmless, reduced, and standardized collection and disposal of garbage.
