Description

Technical Field

[0001] The present invention relates to an automatic monitoring and early warning system, and in particular to an automatic monitoring and early warning system for garbage truck unloading applied in the field of alarm devices. Background Technology

[0002] Garbage trucks are typically designed to integrate at least one container for compressing garbage and are equipped with mechanical devices for automatic or semi-automatic unloading.

[0003] The unloading process of garbage trucks is mainly accomplished by a lifting device controlled by a hydraulic system, including emptying garbage from bins into the truck bed and unloading the garbage from the truck bed to the garbage station. Therefore, precise control and safety of the hydraulic system are crucial during the unloading process. This involves the safety of operators, the accuracy of garbage sorting, compliance with environmental standards, and the maintenance and operational efficiency of the equipment.

[0004] However, current technology primarily relies on operators visually observing the lifting equipment's movements and manually operating control buttons to manage the hydraulic system. This approach not only reduces the ability to accurately assess the lifting device's operational status but also fails to identify problems in their early stages, thereby increasing safety risks for operators and those nearby during the unloading process. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to accurately determine the operating status of the lifting device during garbage truck unloading operations and effectively identify initial faults, thereby ensuring the safety of operators and surrounding personnel.

[0006] To solve the above problems, the present invention provides an automatic monitoring and early warning system for unloading garbage trucks, including a garbage truck body and an automatic monitoring and early warning processing unit mounted in the driver's cab of the garbage truck body. A garbage storage compartment is installed at the rear of the garbage truck body, a garbage station tipper is rotatably installed at the rear of the garbage storage compartment, and a garbage bin tipper is rotatably connected to the rear of the garbage station tipper.

[0007] The rear sides of the left and right ends of the garbage storage compartment and the rear sides of the left and right ends of the garbage station tipping bucket are rotatably connected to the unloading and lifting structure.

[0011] The aforementioned automatic monitoring and early warning system for garbage truck unloading can, on the one hand, perform accompanying data monitoring on the operating status of the unloading lifting structure, enabling accurate judgment of the operating status of the unloading lifting structure; on the other hand, it can also promptly identify and handle the initial stage of operational failures in the unloading lifting structure, effectively maintaining the stable operation of the unloading lifting structure, thereby increasing the safety of operators and surrounding personnel during the unloading process.

[0012] As a supplement to this application, the unloading lifting structure includes lifting cylinders respectively rotatably mounted on the garbage storage bin and the garbage station tipper. A lifting plug is slidably connected inside the lifting cylinder. A lifting rod is fixedly connected to the lower end of the lifting plug. The lower end of the lifting rod extends to the outside of the lifting cylinder and is rotatably connected to the corresponding garbage bin tipper and garbage station tipper. A sealing gasket is fixedly connected to the lower end of the lifting cylinder, and the sealing gasket and the lifting rod are in a sealing sliding fit.

[0013] As a supplement to this application, the hydraulic branch pipe is connected to the lifting cylinder, and the connection position is located on the upper side of the lifting plug when it is in the closed state. The hydraulic branch pipe can be controlled by the hydraulic unloading system. By introducing and extracting hydraulic oil into the lifting cylinder located on the upper side of the lifting plug, the movement control of the lifting plug in the lifting cylinder can be realized, thereby realizing the extension and retraction of the lifting rod.

[0014] As a supplement to this application, the lifting accompanying structure includes an accompanying connecting block fixedly sleeved on the outer end of the lifting cylinder, an accompanying cylinder fixedly connected inside the accompanying connecting block, an accompanying connecting pipe fixedly connected to the lower end of the accompanying cylinder and communicating with it, the other end of the accompanying connecting pipe communicating with the lifting cylinder, and the connection position is located below the lifting plug when in the fully lifted state, a flow rate detector is fixedly installed on the accompanying connecting pipe, and the input end of the lifting accompanying monitoring unit is connected to the signal of the flow rate detector.

[0015] As a further improvement of this application, an upper fixed plate is fixedly connected to the inner wall of the accompanying connecting block, and an elastic accompanying sleeve is fixedly connected to the lower end of the upper fixed plate. An accompanying sliding plug that is in a sealing sliding fit with the inner wall of the accompanying connecting block is fixedly connected to the lower end of the elastic accompanying sleeve.

[0018] As another improvement of this application, the output of the automatic monitoring and early warning processing unit is also connected to the lifting force control unit, and the output of the lifting force control unit is connected to the signal of the protective electromagnetic plate.

[0019] In summary, by incorporating the lifting accompanying structure, lifting accompanying monitoring unit, and lifting control compensation unit, the system can, on the one hand, perform accompanying data monitoring of the unloading lifting structure's operating status when the hydraulic unloading system controls its movements, effectively improving monitoring accuracy and enabling precise judgment of the unloading lifting structure's operating status. On the other hand, the accompanying monitoring function can effectively identify operational faults in the unloading lifting structure in its early stages. Then, the lifting control compensation unit can compensate for the hydraulic unloading system's control of the unloading lifting structure's movements, effectively maintaining the stable operation of the unloading lifting structure. This increases the safety of operators and surrounding personnel during the unloading process. Furthermore, if the compensation for the unloading lifting structure's fault is ineffective, an alarm can be generated to further reduce the scope of the fault's impact, serving as a warning to operators and surrounding personnel and improving the safety of the garbage truck itself during the unloading process.

Detailed Implementation

[0033] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] Implementation method 1:

[0035] Figure 1 - Figure 6 , Figure 10 and Figure 11 The automatic monitoring and early warning system for unloading garbage trucks is shown, including a garbage truck body 1 and an automatic monitoring and early warning processing unit installed in the cab of the garbage truck body 1. A garbage storage compartment 13 is installed at the rear end of the garbage truck body 1. A garbage station tipping bucket 12 is rotatably installed at the rear end of the garbage storage compartment 13. A garbage bin tipping bucket 11 is rotatably connected to the rear end of the garbage station tipping bucket 12. The garbage station tipping bucket 12 and the garbage bin tipping bucket 11 cooperate to form a sealed space for the garbage storage compartment 13.

[0036] The rear sides of the left and right ends of the garbage storage compartment 13 and the rear sides of the left and right ends of the garbage station tipping bucket 12 are rotatably connected to the unloading and lifting structure 3. The lower end of the unloading and lifting structure 3 on the garbage storage compartment 13 is rotatably connected to the garbage station tipping bucket 12, and the lower end of the unloading and lifting structure 3 on the garbage station tipping bucket 12 is rotatably connected to the garbage bin tipping bucket 11.

[0037] The upper end of the garbage truck body 1 is equipped with a hydraulic unloading system 2. The rear end of the unloading lifting structure 3 is fixedly connected to a hydraulic branch pipe 21 that is connected to it, and the other end of the hydraulic branch pipe 21 is connected to the hydraulic unloading system 2. The outer end of the unloading lifting structure 3 is also equipped with a lifting accompanying structure 4 that is connected to it.

[0038] The input end of the automatic monitoring and early warning processing unit is connected to the unloading command acquisition unit, the unloading parameter setting unit and the hoisting accompanying monitoring unit, and the output end of the automatic monitoring and early warning processing unit is connected to the hoisting control unit, the hoisting control compensation unit and the abnormal warning unit.

[0039] The input terminals of the unloading command acquisition unit and the unloading parameter setting unit are both connected to the control panel located in the cab of the garbage truck body 1. The input terminal of the lifting accompanying monitoring unit is connected to the lifting accompanying structure 4. The output terminal of the lifting control unit is connected to the hydraulic unloading system 2. The output terminal of the lifting control compensation unit is connected to the lifting control unit. The output terminal of the abnormal warning unit is connected to the alarm located on the garbage storage compartment 13. Through the setting of the lifting accompanying structure 4, the lifting accompanying monitoring unit, and the lifting control compensation unit, the operating status of the unloading lifting structure 3 can be monitored in tandem when the hydraulic unloading system 2 controls the unloading lifting structure 3 to move. This effectively improves monitoring accuracy, enabling precise judgment of the operating status of the unloading lifting structure 3. On the other hand, through accompanying monitoring, it can effectively identify the initial operational failure of the unloading lifting structure 3. Then, through the lifting control compensation unit, it compensates the hydraulic unloading system 2 for the movement of the unloading lifting structure 3, effectively maintaining the stable operation of the unloading lifting structure 3. This increases the safety of operators and surrounding personnel during the unloading process. Furthermore, it can generate an alarm reminder after the fault compensation of the unloading lifting structure 3 is ineffective, further reducing the scope of the fault's impact and serving as a warning to operators and surrounding personnel, thereby improving the safety of the garbage truck body 1 during the unloading process.

[0040] Figure 3 - Figure 6 The unloading lifting structure 3 includes lifting cylinders 31 that are rotatably mounted on the garbage storage bin 13 and the garbage station tipping bucket 12, respectively. A lifting plug 33 is slidably connected inside the lifting cylinder 31. A lifting rod 32 is fixedly connected to the lower end of the lifting plug 33. The lower end of the lifting rod 32 extends to the outside of the lifting cylinder 31 and is rotatably connected to the corresponding garbage bin tipping bucket 11 and garbage station tipping bucket 12. A sealing gasket is fixedly connected to the lower end of the lifting cylinder 31, and the sealing gasket and the lifting rod 32 are in a sealed sliding fit. The lifting rod 32 and the lifting cylinder 31 form a sealed sliding fit through the sealing gasket, which can effectively ensure the accuracy of the monitoring of the movement of the lifting plug 33 in the lifting cylinder 31 by the lifting accompanying structure 4, improve the accuracy of judging the operating status of the unloading lifting structure 3, promote the subsequent guarantee of the stable and safe operation of the unloading lifting structure 3, and effectively ensure the personal safety of the operators and surrounding personnel.

[0041] Figure 3 - Figure 6 The hydraulic branch pipe 21 is connected to the lifting cylinder 31, and the connection position is located above the lifting plug 33 when it is in the closed state. The hydraulic branch pipe 21 can be controlled by the hydraulic unloading system 2. By introducing and extracting hydraulic oil into the lifting cylinder 31 located above the lifting plug 33, the movement control of the lifting plug 33 in the lifting cylinder 31 can be realized, thereby realizing the extension and retraction of the lifting rod 32.

[0042] Figure 1 - Figure 6 , Figure 10 and Figure 11 The lifting accompanying structure 4 includes an accompanying connecting block 41 fixedly sleeved on the outer end of the lifting cylinder 31. An accompanying cylinder 42 is fixedly connected inside the accompanying connecting block 41. An accompanying connecting pipe 43 is fixedly connected to the lower end of the accompanying cylinder 42 and communicates with it. The other end of the accompanying connecting pipe 43 is connected to the lifting cylinder 31, and the connection position is located below the lifting plug 33 when it is in the fully lifted state. A flow rate detector 44 is fixedly installed on the accompanying connecting pipe 43. The input end of the lifting accompanying monitoring unit is connected to the flow rate detector 44. The cooperation between the flow rate detector 44 and the lifting accompanying monitoring unit can effectively realize the real-time monitoring of the operating status of the unloading lifting structure 3. It can promptly monitor and transmit data when the unloading lifting structure 3 malfunctions in the early stage of operation, so that the automatic monitoring and early warning processing unit can promptly handle and warn of the malfunction, which can significantly improve the monitoring accuracy and response efficiency of the unloading lifting structure 3 malfunction, and effectively ensure the safety of the garbage truck body 1 and the surrounding personnel during the unloading process.

[0043] Figure 3 - Figure 6 The accompanying connecting block 41 has an upper fixed plate 51 fixedly connected to its inner wall. An elastic accompanying sleeve 6 is fixedly connected to the lower end of the upper fixed plate 51. An accompanying sliding plug 5, which has a sealing sliding fit with the inner wall of the accompanying connecting block 41, is fixedly connected to the lower end of the elastic accompanying sleeve 6. An auxiliary spring 61, sleeved on the outside of the elastic accompanying sleeve 6, is also fixedly connected between the accompanying sliding plug 5 and the upper fixed plate 51. It should be noted that when the elastic accompanying sleeve 6 and the auxiliary spring 61 are not under stress, their length is half the length of the accompanying cylinder 42. When the unloading lifting structure 3 is in the closed state, the elastic accompanying sleeve 6 and the auxiliary spring 61 are elastically stretched, resulting in elongation deformation. When the lifting structure 3 is in the fully raised state, the elastic accompanying sleeve 6 and the auxiliary spring 61 are elastically compressed, producing contraction deformation. The cooperation of the elastic accompanying sleeve 6 and the auxiliary spring 61 can not only provide accompanying monitoring of the movement of the lifting plug 33 by the lifting accompanying structure 4, but also effectively play the role of lifting buffer, improving the smoothness of the movement of the unloading lifting structure 3. Through the effect of resistance buffering, it can reduce the mechanical damage during the operation of the unloading lifting structure 3, as well as reduce the mechanical damage during the operation of the garbage bin tipper 11 and the garbage station tipper 12, and extend the durability of the garbage truck body 1 and its structure.

[0044] Figure 1 - Figure 6 , Figure 10 and Figure 11As shown, when the automatic monitoring and early warning system is applied to the garbage truck body 1, the technician first inputs the unloading parameters into the unloading parameter setting unit through the control panel. These parameters include the lifting speed, average speed standard, compensable range, warning standard, and number of cycles for judging invalid lifting compensation of the unloading lifting structure 3. Then, the unloading parameter setting unit transmits the above parameters to the automatic monitoring and early warning processing unit, which identifies, processes, and applies these data.

[0045] In the subsequent application of the garbage truck body 1, the operator first sends a unloading command to the unloading command acquisition unit via the touch control panel. This allows the automatic monitoring and early warning processing unit to determine the position of the unloading lifting structure 3 that needs to be controlled based on the received unloading command. For example, when it is necessary to open the garbage bin tipper 11, the two unloading lifting structures 3 installed on the garbage station tipper 12 are controlled; when it is necessary to open the garbage station tipper 12, the two unloading lifting structures 3 installed on the garbage storage compartment 13 are controlled. Then, the automatic monitoring and early warning processing unit sends a control command to the lifting control unit, enabling... The lifting control unit sends a control command to the hydraulic unloading system 2, causing the hydraulic unloading system 2 to input hydraulic oil into the lifting cylinder 31 of the corresponding unloading lifting structure 3 located on the upper side of the lifting plug 33 through the hydraulic branch pipe 21. The hydraulic oil pressurizes the lifting plug 33, causing it to move downward in the lifting cylinder 31, which drives the lifting rod 32 to move downward together, causing the lifting rod 32 to slide out from the lifting cylinder 31, opening the distance between the garbage bin tipping bucket 11 and the garbage station tipping bucket 12 or the garbage station tipping bucket 12 and the garbage storage compartment 13, thus causing the garbage bin tipping bucket 11 or the garbage station tipping bucket 12 to be opened.

[0046] When the lifting plug 33 and lifting rod 32 move within the lifting cylinder 31, causing the garbage bin tipper 11 or garbage station tipper 12 to be opened, the downward movement of the lifting plug 33 will cause the gas inside the lifting cylinder 31 located below the lifting plug 33 to flow into the accompanying cylinder 42 through the accompanying connecting pipe 43. At this time, the flow rate detector 44 located on the accompanying connecting pipe 43 can collect the gas flow rate and then transmit it to the lifting accompanying monitoring unit. The gas entering the accompanying cylinder 42 will exert a squeezing and pushing effect on the accompanying sliding plug 5, causing the accompanying sliding plug 5 to move upward within the accompanying cylinder 42 and squeeze the elastic accompanying sleeve 6 and auxiliary spring 61. At this time, the elastic accompanying sleeve 6 and auxiliary spring 61 can generate a damping effect on the lifting operation of the unloading lifting structure 3, which can effectively alleviate the instantaneous impact of hydraulic oil on the lifting plug 33, achieve the effect of slow start-up, and avoid structural damage caused by excessive starting speed, as well as the safety of operators and surrounding personnel.

[0047] The lifting accompanying monitoring unit transmits the flow velocity data to the automatic monitoring and early warning processing unit, enabling the automatic monitoring and early warning processing unit to determine the moving speed of the lifting plug 33 and the lifting cylinder 31 through the flow velocity data, and to determine whether the movement of the lifting plug 33 and the lifting cylinder 31 is uniform through the change value of the flow velocity data per unit time. This effectively improves the accuracy of monitoring the operating status of the unloading lifting structure 3, and can sense and process the unloading lifting structure 3 in the early stage of operating failure, ensuring the safety of personnel in the garbage truck body 1 during the unloading process.

[0048] If the automatic monitoring and early warning processing unit determines that the moving speed of the lifting plug 33 and the lifting cylinder 31 is within the set range and that they are maintaining a constant speed, then no action will be taken, and the hydraulic unloading system 2 will continue to regulate the unloading lifting structure 3 through the hydraulic branch pipe 21.

[0049] When the automatic monitoring and early warning processing unit determines that the moving speed of the lifting piston 33 and the lifting cylinder 31 exceeds the set range or is not uniform, the data is transmitted to the lifting control and compensation unit, so that the lifting control and compensation unit can process and judge the data, and then transmit the data that needs to be compensated to the lifting control unit, so that the lifting control unit can further compensate and control the hydraulic unloading system 2, control the amount and speed of hydraulic oil input into the lifting cylinder 31 through the hydraulic branch pipe 21, ensure the effectiveness of the control of the hydraulic unloading system 2, and ensure the safety of the unloading lifting structure 3 driving the garbage bin tipper 11 or the garbage station tipper 12 to move.

[0050] Then, the automatic monitoring and early warning processing unit judges the effect of the control and compensation based on the flow rate data transmitted by the lifting accompanying monitoring unit. If the control and compensation effect is effective, the control data is maintained. If the control and compensation effect is ineffective or poor, the early warning data is transmitted to the abnormal warning unit, which then activates the alarm set on the garbage storage compartment 13. The alarm activates and issues a warning, which can alert the operators and surrounding personnel, enabling them to quickly evacuate the operating range of the unloading lifting structure 3 and ensure personnel safety. Then, the operators can return to the cab of the garbage truck body 1 and control the unloading action to stop through the control panel and the unloading execution acquisition unit, preventing the unloading lifting structure 3 from continuing to malfunction and allowing for timely inspection and maintenance of the various structures on the garbage truck body 1 to avoid continuous damage and reduce maintenance costs.

[0051] The second implementation method:

[0052] Figure 1 - Figure 4 and Figure 7 - Figure 11The automatic monitoring and early warning system for garbage truck unloading is shown as an extension and functional enhancement of the first embodiment. Protective electromagnetic plates 62 are fixedly connected to both the upper and lower inner walls of the elastic sleeve 6. A protective stop unit is also connected to the output of the automatic monitoring and early warning processing unit. The output of the protective stop unit is signal-connected to the protective electromagnetic plate 62. The cooperation between the protective stop unit and the protective electromagnetic plate 62 enables the automatic monitoring and early warning processing unit to stop and protect the unloading lifting structure 3 from initial malfunctions through the lifting control compensation unit, preventing economic losses caused by the continued spread of the malfunction, reducing the risk of malfunction, and effectively protecting the safety of operators and surrounding personnel.

[0053] Figure 1 - Figure 6 , Figure 10 and Figure 11 The upper fixed plate 51 is shown to be fixedly connected to a pressure probe at its lower end. The input end of the automatic monitoring and early warning processing unit is also connected to a lifting force sensing unit. The input end of the lifting force sensing unit is connected to the pressure probe signal. The output end of the automatic monitoring and early warning processing unit is also connected to a data display unit. The output end of the data display unit is connected to the control panel located in the cab of the garbage truck body 1. The setting of the pressure probe can effectively realize the sensing of the force-relieving effect. Then, based on the weight of the garbage bin tipper 11 and the garbage station tipper 12 and the hydraulic pressure data of the hydraulic unloading system 2 controlling the unloading lifting structure 3, the force-relieving effect generated by the elastic accompanying sleeve 6 can be adjusted. This further expands the application range of the elastic accompanying sleeve 6, making it applicable to different specifications of garbage truck bodies 1, increasing its economic adaptability. It can also judge the wear degree of the elastic accompanying sleeve 6 and the auxiliary spring 61 based on the pressure change. It can react in time after the elastic accompanying sleeve 6 and the auxiliary spring 61 are damaged, so that the operators can replace the elastic accompanying sleeve 6 and the auxiliary spring 61 based on the data display, effectively reducing the maintenance difficulty of the automatic monitoring and early warning system.

[0054] Figure 1 - Figure 4 and Figure 7 - Figure 11The output of the automatic monitoring and early warning processing unit is also connected to a lifting force control unit. The output of the lifting force control unit is connected to the protective electromagnetic plate 62. The lifting force control unit can effectively adjust the force of the elastic accompanying sleeve 6, effectively protect the operation of the garbage bin tipping 11 and the garbage station tipping 12, reduce mechanical damage to the unloading lifting structure 3, and provide force protection for the position of the unloading lifting structure 3 when it is in the raised state. This avoids the problem of the garbage bin tipping 11 or the garbage station tipping 12 falling due to the sudden retraction of the unloading lifting structure 3 caused by the abnormality of the hydraulic unloading system 2. This further ensures the safety of the garbage truck body 1 during the unloading process and can also effectively promote the applicability of the automatic monitoring and early warning system, meet the needs of garbage truck bodies 1 of different specifications, and further promote the economy of the automatic monitoring and early warning system.

[0055] Figure 1 - Figure 4 and Figure 7 - Figure 11 The diagram shows that when the automatic monitoring and early warning processing unit judges the effect of the control and compensation based on the flow rate data transmitted by the hoisting accompanying monitoring unit, and determines that the control and compensation effect is ineffective or poor, the automatic monitoring and early warning processing unit, while activating the abnormal warning unit, also sends a control command to the protection and shut-off unit. This causes the protection and shut-off unit to input current into the protection electromagnetic plate 62, resulting in an electromagnetic repulsion between the two protection electromagnetic plates 62 within the same elastic accompanying sleeve 6. This repulsion counteracts the squeezing force of the hydraulic oil input to the hoisting cylinder 31 by the hydraulic unloading system 2 through the hydraulic branch pipe 21. This prevents the lifting plug 33, lifting rod 32, and garbage bin tipping bucket 11 or garbage station tipping bucket 12 from continuing to operate, thus pausing the malfunction in a timely manner and ensuring the safety of the operators and surrounding personnel. After hearing the alarm, the operators and surrounding personnel evacuate the area around the unloading lifting structure 3. The operators then use the control panel in the cab to pause the hydraulic operation of the hydraulic unloading system 2. This further protects personnel safety and effectively reduces the mechanical damage caused by the continuous operation of the unloading lifting structure 3, thereby reducing the difficulty and cost of subsequent maintenance.

[0056] When the lifting plug 33 is pushed by hydraulic oil, causing the lifting rod 32 to move downwards together, the gas located below the lifting plug 33 enters the accompanying cylinder 42 through the accompanying connecting pipe 43 and pushes the accompanying sliding plug 5 upwards. The accompanying sliding plug 5 then moves closer to the upper fixed plate 51, compressing the space inside the accompanying cylinder 42 between the accompanying sliding plug 5 and the upper fixed plate 51. The pressure probe then transmits the pressure change data to the lifting force sensing unit, which in turn transmits the pressure data to the automatic monitoring and early warning processing unit. The automatic monitoring and early warning processing unit determines the operating status of the unloading lifting structure 3 based on the pressure change data. If the lifting speed is too fast, the unit, while compensating the lifting control unit through the lifting control compensation unit, also sends a control command to the lifting force control unit, enabling the lifting force control unit to pass current into the protective electromagnetic plate 62. The two protective electromagnetic plates 62 inside the elastic accompanying sleeve 6 generate electromagnetic resistance, which increases the contraction resistance of the elastic accompanying sleeve 6 to resist the continuous upward movement of the accompanying sliding plug 5, thereby resisting and mitigating the downward movement of the lifting plug 33. This further regulates the movement speed of the lifting plug 33 and the lifting rod 32, which not only improves the efficiency of regulation, but also increases the adjustable direction when the hydraulic unloading system 2 fails to compensate or has poor effect, further improving the safety of the unloading lifting structure 3 during application. It can also regulate the unloading lifting structure 3 to close and reset or continue to operate through the lifting force control unit after the hydraulic unloading system 2 and the unloading lifting structure 3 malfunction. After the garbage unloading operation is completed, the garbage truck body 1 is maintained to ensure the stability and safety of the garbage truck body 1, thus activating an effective dual regulation function.

[0057] Furthermore, when the automatic monitoring and early warning system is applied to garbage truck bodies 1 of different specifications, it can also supply current to the protective electromagnetic plate 62 by the lifting damping control unit at the same time as the hydraulic unloading system 2 is started. This causes the two protective electromagnetic plates 62 located in the same elastic accompanying sleeve 6 to generate a certain electromagnetic force. This achieves the damping and buffering effect of the elastic accompanying sleeve 6, the auxiliary spring 61 and the electromagnetic repulsion effect of the protective electromagnetic plate 62 on the lifting and closing actions of the unloading lifting structure 3 at the beginning of the lifting and closing actions. This effectively reduces the mechanical damage caused by the weight impact of the garbage bin tipping bucket 11 and the garbage station tipping bucket 12 at the beginning of the lifting and closing actions of the unloading lifting structure 3, as well as the safety hazards to the operators.

[0058] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
