Description

Technical Field

[0001] This invention belongs to the field of sanitation equipment technology, specifically relating to a mobile garbage compressor auxiliary unloading device and unloading method. Background Technology

[0002] Mobile garbage compactors are environmentally friendly devices that integrate sealing, deodorization, compression, and storage functions. They are characterized by cleanliness, aesthetics, safety, high efficiency, and environmental friendliness, enhancing the overall image and appearance of urban areas and communities, and strengthening public awareness and environmental protection concepts. The mobile garbage compactor mainly consists of a garbage storage container, a compression mechanism, a tipping mechanism, and an electro-hydraulic control system. The compressor head and container are integrated into a single unit, remaining connected during garbage collection, compression, and transfer, thus avoiding secondary pollution. The equipment has a small footprint, is convenient and flexible, requires simple supporting facilities, and has low maintenance and operating costs. It can be placed outdoors and transported over long distances, making it suitable for various garbage collection and transfer locations such as streets, hospitals, schools, parks, and squares. It is an ideal choice for urban sanitation departments and various public institutions' garbage disposal equipment.

[0003] Once the garbage container reaches a certain capacity, a hooklift truck is needed to transport the mobile garbage compactor to a centralized processing center, where the garbage is dumped out from the rear door of the container. In existing technologies, garbage dumping relies on the hooklift truck tilting the container upwards, allowing the garbage to be discharged naturally by gravity, which is inefficient.

[0024] Reference Figures 1 to 5 An embodiment of the present invention provides a mobile garbage compressor auxiliary unloading device, comprising: The garbage compressor body 101 includes a compression mechanism and a tailgate opening and closing mechanism. The compression mechanism is provided with a compression working oil passage 200, and the tailgate opening and closing mechanism is provided with a tailgate working oil passage 100. The compression working oil passage 200 and the tailgate working oil passage 100 are connected in parallel to an oil passage switching unit 300. Hooklift truck 103, hooklift truck 103 is equipped with a hydraulic power station, and the hydraulic power station is equipped with an auxiliary oil circuit 400; Among them, the auxiliary oil circuit 400 can be detachably connected to the oil circuit switching unit 300, and first connects to the tailgate working oil circuit 100 to open the tailgate 102, and then connects to the compression working oil circuit 200 to control the compression mechanism to extend and push the material.

[0025] In this embodiment, the auxiliary unloading device for the mobile garbage compressor allows the auxiliary oil circuit 400 to be connected to the oil circuit switching unit 300 when the hooklift truck 103 transports the garbage compressor body 101 to the centralized processing center. The hydraulic power station of the hooklift truck 103 is then used to control the opening and closing of the tailgate 102 and the extension and retraction of the compression mechanism. Specifically, the tailgate working oil circuit 100 can be connected first to control the tailgate 102 to open, and then the compression working oil circuit 200 can be connected to control the compression mechanism to extend and actively push out the garbage, thereby improving discharge efficiency.

[0026] It is understandable that when the garbage compressor body 101 is placed at the collection site for garbage collection and storage, the on-site workstation provides the compression power source. It can be directly connected to the compression working oil circuit 200 for compression operations, or the corresponding oil circuit can be set up in parallel for compression operations. Therefore, the structural configuration in this embodiment is simple and will not hinder the normal operation process of the garbage compressor body 101.

[0027] Since the garbage compactor body 101 empties garbage from containers such as garbage bins or hoppers into its interior and then compresses and holds it, the tailgate 102 remains closed throughout this process. Therefore, the garbage inside can easily become compressed and fixed together due to compression, leading to incomplete unloading or even failure to unload. This embodiment utilizes an extended compression mechanism to push the garbage out. The design is simple, the manufacturing cost is low, and it is easy to operate and maintain. This helps the garbage compactor unload garbage more efficiently, reducing garbage scattering and secondary pollution, and significantly shortening unloading time.

[0028] In some embodiments of the present invention, the oil circuit switching unit 300 includes a manual reversing valve 301, which is provided with a first valve passage 302, a second valve passage and a third valve passage. The first valve passage 302 is provided with a quick connector at its end, the second valve passage is connected to the compression working oil circuit 200 and the third valve passage is connected to the tailgate working oil circuit 100.

[0029] During the unloading operation, first connect the quick connector to the auxiliary oil circuit 400, then manually switch the third valve passage to connect to the first valve passage 302 to control the tailgate 102 to open. After the tailgate 102 is fully open, manually switch the second valve passage to connect to the first valve passage 302 and control the compression mechanism to extend to assist in pushing out the waste. After the waste is unloaded, reset the components sequentially, and finally disconnect the quick connector and the auxiliary oil circuit 400.

[0030] Since the operation requires workers to make judgments, the manual switching method allows workers to adjust according to the actual situation, making it highly operable.

[0031] In some embodiments of the present invention, hydraulic locks are provided between the compression working oil passage 200 and the second valve passage, and between the tailgate working oil passage 100 and the third valve passage. These hydraulic locks are used to prevent hydraulic oil backflow.

[0032] In some embodiments of the present invention, a manual reversing valve 301 is disposed on the side of the garbage compressor body 101 and near the tailgate 102.

[0033] As can be seen from the foregoing embodiments, since workers need to check the opening status of the tailgate 102 and the unloading status during the unloading operation, this embodiment sets the manual reversing valve 301 near the tailgate 102 to facilitate workers to check the opening and closing status of the tailgate 102 during operation.

[0034] Combination Figure 4 In some embodiments of the present invention, a protective box 104 is provided on the side of the garbage compressor body 101. The protective box 104 has an open state and a closed state. When the protective box 104 is in the closed state, the protective box 104 covers the oil circuit switching part 300. When the protective box 104 is in the open state, the oil circuit switching part 300 is exposed.

[0035] This embodiment, by providing a protective box 104, can cover the oil circuit switching section 300 under normal conditions, preventing damage to the quick connector and manual directional valve 301. It can only be opened when needed, which helps extend the service life of the equipment and ensures safe operation.

[0036] In some embodiments of the present invention, the upper end of the protective box 104 is rotatably connected to the garbage compressor body 101. Normally, the protective box 104 covers the oil circuit switching section 300, including a quick-connect coupling and a manual reversing valve 301. When unloading is required, the protective box 104 can be flipped upwards.

[0037] To prevent the protective box 104 from being opened arbitrarily, a ratchet structure is provided at the rotational connection between the protective box 104 and the garbage compressor body 101. This ratchet structure provides rotational damping for the protective box 104 and keeps it relatively fixed relative to the garbage compressor body 101. The damping force of the ratchet structure's lever 1051 can be adjusted by changing its clamping force. For example, the greater the clamping force of the lever 1051, the greater the resistance that needs to be overcome during rotation, and therefore the stronger the damping effect.

[0038] Combination Figure 5Specifically, a mounting base 105 is provided on the garbage compressor body 101, and a protective box 104 is rotatably connected to the side of the mounting base 105 facing away from the tailgate 102. A ratchet is provided on the end face of the protective box 104 facing the mounting base 105, and the ratchet is coaxially distributed with the rotation center of the protective box 104. A lever 1051 is slidably provided on the mounting base 105, and the sliding direction of the lever 1051 is parallel to the rotation center of the protective box 104. The lever 1051 corresponds to the ratchet tooth 1041 on the ratchet to engage the ratchet tooth 1041. A spring is provided at the end of the lever 1051 away from the ratchet.

[0039] Under normal conditions, the lever 1051 engages with the ratchet under the action of the spring, ensuring the relative stability of the protective box 104. When an external force is applied to the protective box 104, it can overcome the spring force and rotate relative to the lever 1051.

[0040] Continue to refer to Figure 5 Furthermore, the ratchet teeth 1041 of the ratchet include a first tooth surface 1043 facing the upward opening direction and a second tooth surface 1042 facing away from the upward opening direction. When the protective box 104 is opened upward, the second tooth surface 1042 pushes the lever 1051 outward to skip teeth. In this embodiment, the second tooth surface 1042 is set as an oblique tooth surface, and the first tooth surface 1043 is set as a vertical surface, so that the second tooth surface 1042 can push the lever 1051 upward, while the first tooth surface 1043 cannot push the lever 1051 downward. With the structural setting of this embodiment, the protective box 104 can be opened upward normally, but will be locked downward, requiring manual disengagement of the lever 1051 to close downward. This ensures stability during unloading operations and avoids uncontrolled closing that could affect the connection with the auxiliary oil circuit 400.

[0041] Based on this, the protective box 104 is made of metal. Furthermore, a striking rod 1044 is provided between the tooth grooves of two adjacent ratchet teeth 1041, and the striking rod 1044 does not contact the tooth surface of the ratchet teeth 1041. The head of the lever 1051 can abut against the striking rod 1044. Each time a tooth skips, because the first tooth surface 1043 is a vertical surface, the lever 1051 can quickly return to its original position after passing the second tooth surface 1042, striking the striking rod 1044. At this time, the protective box 104 itself forms a sound bowl structure that amplifies the sound, thus amplifying and processing the striking sound. Therefore, when the protective box 104 is opened upwards, the operator can hear a clear but not harsh striking sound, which can be used as a reminder to prevent other personnel from accidentally operating the device.

[0042] Understandably, increasing the strength of the springs would increase the force required for the protective box 104 to flip.

[0043] In some embodiments of the present invention, the auxiliary oil circuit 400 and the oil circuit switching part 300 are connected by a quick-connect structure to improve the efficiency of disassembly and assembly.

[0044] In some embodiments of the present invention, the hooklift truck 103 is provided with a tool box at the position corresponding to the oil circuit switching part 300, and the auxiliary oil circuit 400 is partially wound up in the tool box.

[0045] It is understandable that the auxiliary oil circuit 400 also has a connector. In this embodiment, the auxiliary oil circuit 400 is stored in a tool box, which can protect it and prevent the auxiliary oil circuit 400 from falling off and being damaged due to the long-term bumping of the hooklift truck 103.

[0046] Embodiments of the present invention also provide a method for unloading materials from a mobile garbage compactor, comprising: Connect the auxiliary oil circuit 400 and the oil circuit switching unit 300; First, connect the tailgate working oil circuit 100 to the auxiliary oil circuit 400, and then control the tailgate 102 to open. Disconnect the tailgate working oil circuit 100 and control the compression working oil circuit 200 to connect to the auxiliary oil circuit 400, and control the compression mechanism to extend; After the garbage is discharged, the compression mechanism is retracted and the compression working oil circuit 200 is disconnected. The tailgate working oil circuit 100 is connected to the auxiliary oil circuit 400, and the tailgate 102 is closed.

[0047] The unloading method in this embodiment utilizes the hydraulic power station of the hooklift truck 103 to control the opening and closing of the tailgate 102 of the garbage compressor body 101 and the extension of the compression mechanism, which simplifies the power design and improves the unloading efficiency.

[0048] In some embodiments of the present invention, when controlling the extension of the compression mechanism, the total extension stroke D of the compression mechanism is divided into n parts, where n is an integer greater than 1, and the compression mechanism is controlled to extend n times. The first extension distance is (1 / n)*D, and then it retracts. The second extension distance is (2 / n)*D, and then it retracts. This cycle is repeated until the extension distance is D.

[0049] For example, the total extension stroke of the compression mechanism can be divided into two parts. When controlling the extension of the compression mechanism, it is first controlled to extend to half of the total extension stroke, then retracted, and then extended to the total extension stroke again. This two-step approach to waste ejection avoids excessive load that might occur if the compression mechanism is subjected to resistance for an extended period. Furthermore, the retraction and re-extension of the compression mechanism creates an impact on the waste, which helps to loosen the compacted waste and improve unloading efficiency.

[0050] In some embodiments of the present invention, the extension speed of the compression mechanism is increased successively, and the speed can be controlled by the pumping power of the hydraulic oil. That is, the first extension speed is the slowest, and the last extension speed is the fastest.

[0051] Understandably, at the beginning of unloading, the garbage compactor body 101 is at its fullest and most compacted. Slow extension ensures the lifespan of the compression mechanism and facilitates the orderly backward movement of the garbage. Subsequently, as the garbage gradually loosens and is pushed out, the interaction forces and compaction weaken, and increasing the extension speed of the compression mechanism can improve unloading efficiency.

[0052] The specific speed control can be flexibly set as needed, and no specific limitations are made here.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
