Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0024] Referring to Figures 1 to 5 , an auxiliary unloading device for a mobile garbage compressor is proposed in an embodiment of the present invention, including: A garbage compressor body 101, 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 circuit 200, the tailgate opening and closing mechanism is provided with a tailgate working oil circuit 100, and the compression working oil circuit 200 and the tailgate working oil circuit 100 are connected in parallel to an oil circuit switching part 300; A hook arm vehicle 103, the hook arm vehicle 103 is provided with a hydraulic power station, and the hydraulic power station is provided with an auxiliary oil circuit 400; Wherein, the auxiliary oil circuit 400 can be detachably connected to the oil circuit switching part 300, first connect to the tailgate working oil circuit 100 to open the tailgate 102, and then connect to the compression working oil circuit 200 to control the compression mechanism to extend and push the material.

[0025] For the auxiliary unloading device of the mobile garbage compressor in this embodiment, when the hook-arm vehicle 103 transports the garbage compressor body 101 to the centralized treatment center, the auxiliary oil circuit 400 can be connected to the oil circuit switching part 300, and the hydraulic power station of the hook-arm vehicle 103 is used to control the opening and closing of the tailgate 102 and the telescoping of the compression mechanism. Specifically, the tailgate working oil circuit 100 can be connected first to control the opening of the tailgate 102, and then the compression working oil circuit 200 can be connected to control the telescoping of the compression mechanism to actively push out the garbage, so as to improve the discharge efficiency.

[0026] It can be understood that when the garbage compressor body 101 is placed at the collection site for garbage collection and loading, by using the compression power source provided by the on-site workstation, the compression working oil circuit 200 can be directly connected for compression operation, or the corresponding oil circuits can be arranged in parallel for compression operation. Therefore, the structural setting in this embodiment has a simple structure and does not interfere with the conventional operation process of the garbage compressor body 101.

[0027] Since the garbage compressor body 101 dumps the garbage in containers such as trash cans or garbage hoppers into it and then compresses and loads it, the tailgate 102 always remains closed during this process. Therefore, the garbage inside is easily pressed and fixed due to compression, resulting in incomplete unloading or inability to unload. This embodiment uses the telescoping of the compression mechanism to push out the garbage. The design structure is simple, the manufacturing cost is low, it is easy to operate and maintain, it can help the garbage compressor unload garbage more efficiently, reduce garbage scattering and secondary pollution, and can greatly shorten the unloading time.

[0028] In some embodiments of the present invention, the oil circuit switching part 300 includes a manual reversing valve 301. The manual reversing valve 301 is provided with a first valve passage 302, a second valve passage, and a third valve passage. Among them, a quick connector is provided at the end of the first valve passage 302, 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] When performing the unloading operation, first connect the quick connector to the auxiliary oil circuit 400, then manually switch the third valve passage to communicate with the first valve passage 302 to control the opening of the tailgate 102. After the tailgate 102 is opened in place, then manually switch the second valve passage to communicate with the first valve passage 302 and control the compression mechanism to extend to assist in pushing out the garbage. After the garbage unloading is completed, reset in sequence, and finally disconnect the quick connector and the auxiliary oil circuit 400.

[0030] Since it is necessary to rely on workers to make judgments during the operation, the manual switching method is convenient for workers to adjust according to the actual situation, and the operability is high.

[0031] In some embodiments of the present invention, a hydraulic lock is provided between the compression working oil circuit 200 and the second valve passage, and between the tailgate working oil circuit 100 and the third valve passage. The hydraulic lock is used to prevent the hydraulic oil from flowing back.

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

[0033] Combined with the description of the foregoing embodiments, it can be seen that during the unloading operation, the staff needs to check the opening condition of the tailgate 102, the unloading condition, etc. In this embodiment, the manual reversing valve 301 is disposed at a position close to the tailgate 102, which is convenient for the staff to check the opening and closing condition of the tailgate 102 during operation.

[0034] Combined Figure 4 , in some embodiments of the present invention, a protective box 104 is disposed 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] In this embodiment, by providing the protective box 104, the oil circuit switching part 300 can be covered under normal conditions, avoiding damage to the quick connectors and the manual reversing valve 301. And it can be opened when needed, which is beneficial to both extending the service life of the equipment and ensuring 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. Under normal conditions, the protective box 104 covers the oil circuit switching part 300, including the quick connectors and the manual reversing valve 301. When the unloading operation needs to be carried out, the protective box 104 can be turned upward.

[0037] In order to prevent the protective box 104 from being opened randomly, a ratchet structure is provided at the rotational connection between the protective box 104 and the garbage compressor body 101. The ratchet structure is used to provide a damping effect for the rotation of the protective box 104 and to make the protective box 104 relatively fixed with respect to the garbage compressor body 101. By setting the pressing force of the lever 1051 that presses the ratchet in the ratchet structure, the damping force during the rotation of the protective box 104 can be adjusted. For example, the greater the acting force of the lever 1051 pressing the ratchet, the greater the resistance to be overcome during rotation, and thus the stronger the damping effect.

[0038] Combined Figure 5Specifically, a mounting seat 105 is provided on the garbage compactor body 101, and the protection box 104 is rotatably connected to the side of the mounting seat 105 away from the tailgate 102. A ratchet is provided on the end surface of the protection box 104 facing the mounting seat 105, and the ratchet is coaxially distributed with the rotation center of the protection box 104. A lever 1051 is slidably provided on the mounting seat 105, and the sliding direction of the lever 1051 is parallel to the rotation center of the protection box 104. The lever 1051 corresponds to the ratchet teeth 1041 on the ratchet to engage with the ratchet teeth 1041. And a spring is provided at the end of the lever 1051 away from the ratchet.

[0039] Under normal conditions, the lever 1051 engages the ratchet wheel under the action of the spring to ensure the relative stability of the protection box 104. When the protection box 104 is acted upon by an external force, it can overcome the action of the spring and rotate relative to the lever 1051.

[0040] Continue to refer to Figure 5 Furthermore, the ratchet teeth 1041 of the ratchet wheel 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 to withdraw and jump the teeth. In this embodiment, the second tooth surface 1042 is set as a bevel 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 it will be stuck downward, and the lever 1051 needs to be manually opened to close downward, which can ensure the stability during the unloading operation and avoid uncontrolled closing that affects the connection with the auxiliary oil circuit 400.

[0041] On this basis, the protective box 104 is made of metal. In addition, a knocking rod 1044 is provided in the tooth groove between two adjacent ratchets 1041, and the knocking rod 1044 does not contact the tooth surface of the ratchet 1041. The head of the lever 1051 can abut against the knocking rod 1044. Every time the tooth jumps, since the first tooth surface 1043 is a vertical surface, the lever 1051 can be quickly reset after crossing the second tooth surface 1042, causing a knock on the knocking rod 1044. At this time, the protective box 104 itself forms a sound bowl structure that amplifies the volume, and the knocking sound can be amplified and processed. Therefore, when the protective box 104 is flipped upwards, the staff can hear an obvious and non-irritating knocking sound, which can be used as a reminder to avoid misoperation by other personnel.

[0042] It is understandable that increasing the strength of the spring can increase the force required when the protective box 104 is turned over.

[0043] In some embodiments of the present invention, a quick-connect structure is adopted between the auxiliary oil circuit 400 and the oil circuit switching unit 300 to improve the disassembly and assembly efficiency.

[0044] In some embodiments of the present invention, a tool box is provided at the position corresponding to the oil circuit switching unit 300 on the hook-arm vehicle 103, and a part of the auxiliary oil circuit 400 is wound up in the tool box.

[0045] It can be understood that the auxiliary oil circuit 400 also has connectors. In this embodiment, by providing a tool box to store the auxiliary oil circuit 400, protection can be carried out, and the situation that the auxiliary oil circuit 400 falls and is damaged due to the long-term bumping of the hook-arm vehicle 103 can be avoided.

[0046] An embodiment of the present invention also provides a method for unloading a mobile garbage compressor, including: Connecting the auxiliary oil circuit 400 and the oil circuit switching unit 300; First, control the tailgate working oil circuit 100 to communicate with the auxiliary oil circuit 400, and control the tailgate 102 to open; Then, disconnect the tailgate working oil circuit 100, and control the compression working oil circuit 200 to communicate with the auxiliary oil circuit 400, and control the compression mechanism to extend; After the garbage is discharged, control the compression mechanism to retract, disconnect the compression working oil circuit 200, control the tailgate working oil circuit 100 to communicate with the auxiliary oil circuit 400, and control the tailgate 102 to close.

[0047] In the unloading method of this embodiment, the hydraulic power station of the hook-arm vehicle 103 is used 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 can improve the unloading efficiency at the same time.

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

[0049] For example, the total extension stroke of the compression mechanism is divided into two parts. When controlling the compression mechanism to extend, first control the compression mechanism to extend to half of the total extension stroke, then retract, and then control the compression mechanism to extend to the total extension stroke again. In this way, the garbage is pushed out in two steps, avoiding the situation that the compression mechanism may be overloaded due to long-term resistance. Moreover, when the compression mechanism retracts and extends again, it can impact the garbage, which is beneficial to shaking off the compacted garbage and improving the unloading efficiency.

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

[0051] It can be understood that at the beginning of unloading, the garbage in the garbage compressor body 101 is the fullest and the degree of mutual compaction is the greatest. By slowly extending, the service life of the compression mechanism can be ensured, and at the same time, it is beneficial to orderly push the garbage backward. After that, as the garbage is gradually loosened and pushed out, the mutual force and compaction degree are weakened. Increasing the extending speed of the compression mechanism can improve the unloading efficiency.

[0052] Its specific speed control can be flexibly set according to needs and is not specifically limited herein.

[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 without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
