[0009] According to some embodiments of the present invention, the frame is connected to a slide rail, and the pushing mechanism is slidably mounted on the slide rail; the feeding port is located at the end of the slide rail.

[0020] Reference Figure 1 A waste volume reduction baling machine includes: a frame 100, a housing 300, and a pressing mechanism 700; the housing 300 is mounted on the frame 100 and used for loading waste, and the housing 300 is provided with a feeding port 330; the pressing mechanism 700 is disposed on the frame 100, and at least one of the housing 300 and the pressing mechanism 700 can move relative to the frame 100, so that the housing 300 and the pressing mechanism 700 can move relatively closer or relatively farther away; when the pressing mechanism 700 moves relatively away from the housing 300, the feeding port 330 gradually becomes exposed and can be used to feed waste into the housing 300; when the pressing mechanism 700 moves relatively closer to the housing 300 and at least partially overlaps, the pressing mechanism 700 can press the waste in the housing 300. This waste volume reduction and baling machine achieves automatic exposure and closure of the feeding port 330 by allowing the housing 300 and the pressing mechanism 700 to move relative to the frame 100. When the pressing mechanism 700 moves away from the housing 300, the feeding port 330 gradually exposes, facilitating waste input and improving the convenience and efficiency of waste loading. The housing 300 can also directly collect waste centrally. Conversely, when the pressing mechanism 700 moves closer to the housing 300 and at least partially overlaps, it effectively presses the waste within the housing 300, reducing its volume and space requirements for subsequent storage and processing. This integrates waste collection and compression operations, simplifying the waste compression process, increasing automation, reducing manual labor intensity, and improving the overall efficiency of ship waste treatment. This is of great significance for optimizing ship resource allocation and improving the ship environment.
[0021] In practical applications, an electronic control system can be used to control the relative movement of the housing 300 and the pressing mechanism 700, achieving automated waste compression cycles through a preset program. For example, a sensor can be installed to automatically start the equipment when waste is fed into the inlet 330. The pressing mechanism 700 then retracts to fully expose the inlet 330. After the waste is fed in, the pressing mechanism 700 automatically advances to compress the waste. Simultaneously, a pressure sensor can be installed inside the housing 300 to monitor pressure changes in real time during the compression process, ensuring that the waste is fully compressed without being over-compacted and causing equipment damage.
[0022] In some embodiments, reference is made to Figure 3The pressing mechanism 700 includes a pressure plate 200. When the pressing mechanism 700 moves to coincide with the housing 300, it closes the feeding port 330, and the pressure plate 200 enters the housing 300 through the feeding port 330 to push and compress the waste material. This design effectively prevents waste from overflowing from the feeding port 330 during the compression process, ensuring smooth operation and environmental cleanliness. Furthermore, the cooperation between the pressure plate 200 and the feeding port 330 achieves an automatic sealing function, reducing equipment complexity and potential failure points, lowering manufacturing costs and maintenance difficulty, improving equipment reliability and service life, and providing strong support for the efficient compression and treatment of ship waste.
[0023] Furthermore, the pressure plate 200 can be designed as a replaceable structure, allowing for the selection of appropriate materials and shapes based on different waste types and compression requirements. For example, a flat pressure plate 200 can be used for soft waste, while a pressure plate 200 with protrusions or grooves can be used for waste containing hard impurities to enhance the compression effect. Simultaneously, anti-slip textures or coatings can be applied to the surface of the pressure plate 200 to increase friction with the waste, prevent slippage during compression, and improve compression efficiency.
[0024] In some embodiments, reference is made to Figure 2 The pressing mechanism 700 includes a hydraulic cylinder 710 and a hydraulic rod 720. The hydraulic cylinders 710 are connected to and can drive the hydraulic rod 720, which is connected to and can drive the pressure plate 200. The hydraulic cylinders 710 drive the hydraulic rod 720, which in turn drives the pressure plate 200 to perform pushing and compression operations. The hydraulic transmission system has advantages such as high power density, large torque, easy stepless speed regulation, and precise control, providing stable and reliable power support for the pressing mechanism 700. This ensures that the pressure plate 200 can apply sufficient pressure when compressing waste, achieving effective volume reduction of the waste. By adjusting the pressure and flow rate of the hydraulic system, the movement speed and pushing force of the pressure plate 200 can be flexibly controlled to adapt to the compression needs of different types, volumes, and densities of waste.
[0025] It is foreseeable that the hydraulic cylinder 710 and hydraulic rod 720 can be made of high-performance hydraulic components, such as a hydraulic system with a load-sensitive proportional relief valve, which can automatically adjust the system pressure according to the actual load of the pressure plate 200 to achieve energy-saving control.
[0026] In some embodiments, reference is made to Figure 3The pressing mechanism 700 also includes a mounting base 500 and a guide rod 730. The pressure plate 200 is movably mounted on the mounting base 500. The pressure plate 200 is connected to the guide rod 730, which can and can only slide relative to the mounting base 500. The sliding of the guide rod 730 provides stable guidance and support for the movement of the pressure plate 200, ensuring that the pressure plate 200 maintains an accurate movement trajectory during the pushing and compressing of waste materials, and avoiding uneven compression or equipment failure caused by the pressure plate 200's offset or shaking. The guide rod 730 restricts the degree of freedom of the pressure plate 200, allowing it to slide only in a predetermined direction, thus improving the operational stability and reliability of the equipment. At the same time, the mounting base 500, as the supporting foundation for the pressure plate 200 and the guide rod 730, can withstand large pushing forces and the reaction forces of waste materials, ensuring the overall strength and rigidity of the pressing mechanism 700.
[0027] Specifically, the guide rod 730 can be made of high-precision linear guide rail or round steel bar, and undergo surface hardening treatment, such as quenching or hard chrome plating, to improve its wear resistance and fatigue resistance. A sealing and protective device, such as a dust cover or sealing ring, is installed on the guide rod 730 to prevent waste debris, dust, and moisture from entering the gap between the guide rod 730 and the mounting base 500, causing wear or jamming.
[0028] In some embodiments, reference is made to Figure 4 The frame 100 is connected to a slide rail 450, and the pressing mechanism 700 is slidably mounted on the slide rail 450; the feeding port 330 is located at the end of the slide rail 450. The slide rail 450 provides stable guide support for the pressing mechanism 700, ensuring that the pressing mechanism 700 will not deviate or shake during its movement relative to the frame 100, thus improving the operational stability of the equipment and the uniformity of the compression effect. Positioning the feeding port 330 at the end of the slide rail 450 allows it to be fully exposed when the pressing mechanism 700 slides along the slide rail 450 to its outermost position, facilitating rapid loading of waste material. During compression, the pressing mechanism 700 smoothly slides along the slide rail 450 towards the housing 300, gradually compressing the waste material into the housing 300, reducing the scattering and flying of waste material during compression and maintaining a clean working environment. In addition, the 450 slide rail configuration helps to improve the overall structural compactness of the equipment and optimize the spatial layout, enabling the waste reduction baler to be installed and used more flexibly in the limited space of the ship. This improves the space utilization and applicability of the equipment, providing an efficient, stable and easy-to-operate solution for ship waste treatment, which is conducive to improving the ship's waste management level and operational efficiency.
[0029] It is conceivable that the slide rail 450 can be manufactured using I-beams, square steel, or a dedicated slide rail 450 profile, with the appropriate cross-sectional area and strength grade selected based on the weight and motion load of the pushing mechanism 700. The specific implementation method is not unique and can be adjusted accordingly based on actual circumstances; no restrictions are imposed here.
[0030] In some embodiments, reference is made to Figure 2 A stop 430 is provided at the end of the slide rail 450 to prevent the pushing mechanism 700 from moving relative to the slide rail 450. The stop 430 provides effective safety protection and positioning for the equipment. When the pushing mechanism 700 slides to the end of the slide rail 450, the stop 430 can promptly stop its continued movement, preventing the pushing mechanism 700 from detaching from the slide rail 450 due to inertia or operational errors, thus avoiding equipment damage and potential safety accidents. Simultaneously, the stop 430 also provides a clear stopping position for the pushing mechanism 700, ensuring that it accurately positions itself each time it retracts to the end of the slide rail 450, facilitating waste material input and cyclical operation of the equipment. This design improves the operational safety and reliability of the equipment, extends its service life, reduces maintenance costs and unexpected downtime, ensures the stable operation of the ship waste compressor, provides more reliable equipment support for ship waste treatment, and helps improve the safety and efficiency of ship operations.
[0031] Specifically, the stop 430 can be designed as an adjustable baffle or a mechanical locking device, fixed to the end of the slide rail 450 by bolts. Simultaneously, anti-collision rubber pads or elastic buffer materials are installed on the stop 430 to reduce the impact force between the pushing mechanism 700 and the stop 430, thereby reducing equipment vibration and noise. Furthermore, the stop 430 can be linked with the equipment's control system. When the pushing mechanism 700 contacts the stop 430, a limit switch or sensor is triggered, sending a signal to the control system to automatically stop the movement of the pushing mechanism 700, achieving both automated control and safety protection functions. To improve the equipment's intelligence level, a proximity sensor can be installed on the stop 430 to detect the approach of the pushing mechanism 700 in advance and adjust the stop 430's operating mode accordingly, such as activating the buffer device in advance, further improving the equipment's safety and reliability.
[0032] In some embodiments, reference is made to Figure 3The pressing mechanism 700 includes a mounting base 500, on which a pressure plate 200 for pressing waste material is mounted. Multiple rollers 530 are mounted on the side of the mounting base 500 and are movably mounted on a slide rail 450. The rollers 530 significantly reduce the frictional resistance between the pressing mechanism 700 and the slide rail 450, improving the sliding efficiency and motion stability of the pressing mechanism 700. The rollers 530 allow the pressing mechanism 700 to roll easily on the slide rail 450, reducing the frictional force that the drive device needs to overcome, reducing energy consumption, and improving the energy efficiency ratio of the equipment. Simultaneously, the rolling motion of the rollers 530 on the slide rail 450 ensures that the pressing mechanism 700 always maintains an accurate direction of movement, avoiding motion deviation and jamming caused by sliding friction, thus improving the operating accuracy and reliability of the equipment. It is conceivable that roller 530 can be made of high-strength engineering plastics or rubber, possessing good wear resistance and shock absorption performance. The bearings of roller 530 should be selected as high-precision, high-load-capacity types, and feature a sealed design to prevent waste debris and dust from entering the bearing and causing damage.
[0033] In some embodiments, reference is made to Figure 2 The feeding port 330 is located at the top of the housing 300. A door panel 350 is movably installed on the side of the housing 300. When the door panel 350 moves to overlap with the housing 300, it can prevent the waste material inside the housing 300 from detaching from the side of the housing 300. When the side door panel 350 is closed, it can effectively prevent the waste material from overflowing or scattering from the side of the housing 300 during the compression process, keeping the surrounding environment clean and hygienic. The movable design of the door panel 350 allows for quick opening of the door panel 350 when it is necessary to clean the inside of the housing 300 or remove the compressed waste bag, facilitating the operation by the operator. Furthermore, the combined design of the top feeding port 330 and the side door panel 350 optimizes the structural layout of the box 300, improves the space utilization of the box 300, and allows the waste to be distributed more evenly within the box 300. This facilitates the pushing mechanism 700 to fully compress the waste, improving the effect and efficiency of waste compression. This provides a practical and reliable solution for the efficient treatment of ship waste, and helps to improve the ship environment and enhance the convenience of waste management.
[0034] Furthermore, the door panel 350 can be installed on the side of the container 300 using a hinge connection, with the opening and closing of the door panel 350 achieved by rotating the hinge. The hinge should be made of high-strength, corrosion-resistant materials, such as stainless steel or special alloys, to meet the requirements of marine environments. In addition, reinforcing ribs or frame structures can be installed on the outside of the door panel 350 to improve its impact resistance and structural strength, preventing deformation or damage during waste compression. To facilitate operator observation of the waste inside the container 300, a transparent observation window can be installed on the door panel 350, made of scratch-resistant and wear-resistant transparent materials, such as tempered glass or acrylic sheet. Simultaneously, a guide ramp or funnel device can be installed around the feeding port 330 at the top of the container 300 to guide the waste smoothly into the container 300, reducing the accumulation and scattering of waste around the feeding port 330. The size and shape of the feeding port 330 can be adjusted according to different types of waste and loading methods, such as being round, square or polygonal, to meet the needs of ships in different waste treatment scenarios.
[0035] In some embodiments, reference is made to Figure 5 A latch 357 is provided between the housing 300 and the door panel 350. The latch 357 is used to relatively fix the housing 300 and the door panel 350 when the door panel 350 moves to overlap with the housing 300. The latch 357 ensures the sealing and stability of the door panel 350 in the closed state, preventing the door panel 350 from being accidentally opened due to swaying during ship navigation, the pushing force of waste materials, or other external forces, which could cause waste leakage and safety hazards. Through the reliable fixation of the latch 357, the door panel 350 can fit tightly against the housing 300, enhancing the overall integrity and structural strength of the housing 300, making the housing 300 more stable when loading and compressing waste materials, and improving the safety and reliability of equipment operation. At the same time, the latch 357 is simple and convenient to operate, allowing for quick locking and unlocking after the door panel 350 is closed, saving operation time and improving the efficiency of equipment use.
[0036] It is foreseeable that the latch 357 can adopt a variety of structural forms, such as a horizontal bar latch 357, a snap latch 357, or a rotary latch 357, which can be selected according to actual usage requirements and the structure of the housing 300.
[0037] In some embodiments, reference is made to Figure 1The frame 100 is equipped with multiple casters 150 at its bottom. These casters 150 allow operators to easily move the equipment within the ship's hold without the need for large handling equipment or excessive manpower, saving time and labor costs. Simultaneously, the casters 150 adapt to different terrains and slopes on the ship's deck, ensuring the stability and safety of the equipment during movement and preventing damage and accidents caused by tipping or sliding. Furthermore, the flexibility of the casters 150 facilitates the rapid evacuation of the equipment from the work area in emergencies, providing additional assurance for the safe operation of the ship. By improving the equipment's mobility, the casters 150 enhance the applicability and practicality of the waste volume reduction baler on ships, enabling the equipment to better meet the diverse needs of ship waste disposal, improving the flexibility and efficiency of ship waste management, and creating a cleaner and more orderly working environment for the ship.
[0038] Specifically, the caster 150 can be equipped with either swivel casters or fixed casters with braking function to meet different movement and securing needs. Swivel casters allow the equipment to turn flexibly within the cabin and adapt to complex layouts; fixed casters provide better linear movement stability and load-bearing capacity.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
