Description

Technical Field

[0001] The utility model relates to the field of restaurant kitchen garbage trucks, and in particular to a fixed bucket position lifting mechanism and a restaurant kitchen garbage truck. Background Art

[0002] Under the current urban solid waste management system, the collection and transportation of food waste mainly adopts the well-known hanging bucket operation method, that is, the food waste truck uses a hook device to pick up standardized garbage cans placed in various streets and alleys one by one to achieve centralized collection and transportation of garbage. However, this traditional model is gradually revealing its limitations and potential risks, especially in the treatment of grease waste.

[0003] Plastic trash cans, as an indispensable part of urban life, have long been widely adopted due to their lightness and low cost. However, in the special environment of kitchen waste, the long-term immersion and corrosion of grease puts these plastic containers to a severe test. The chemical properties of grease will accelerate the breakage rate between plastic molecules and accelerate their aging process. Over time, the structural strength of plastic barrels will significantly decrease, and the risk of breakage or even accidental falling during transportation will increase, which not only causes a waste of resources, but also poses a safety hazard.

[0004] Faced with the increasingly prominent drawbacks of the traditional model, especially the demand for efficient recycling of new edible oil waste, the industry is actively exploring more adaptable solutions. Unlike general kitchen waste, the recycling of waste oil must not only consider the capacity and load-bearing capacity, but also focus on the sealing and corrosion resistance of the container. Therefore, relying solely on plastic trash cans can no longer meet the development needs of this segment. Instead, diversified and professional collection containers have emerged. They can undertake the task of initial collection and short-distance transportation of waste oil in specific places such as canteens and hotels, or in narrow areas that are inconvenient for large trash cans to reach.

[0005] In order to solve the transportation problems caused by diversified containers, the new generation of kitchen waste collection vehicles are equipped with a built-in closed collection and transportation mechanism, which has greater flexibility and compatibility. This design not only ensures the safety and hygiene of waste oil during the entire collection process and prevents leakage and pollution, but also effectively connects various containers, regardless of their shape and size, to achieve smooth and efficient loading and unloading operations, greatly improving the convenience and efficiency of on-site operations.

[0006] However, the waste collection systems of existing food waste collection vehicles often sacrifice measurement accuracy due to complex force transmission links, and are in urgent need of improvement. Utility Model Content

[0007] In view of this, the present utility model provides a fixed bucket position lifting mechanism. By directly contacting the horizontal plate of the hanging plate connecting plate with the weighing sensor, the force transmission distance is effectively shortened, and the errors that may be introduced in the intermediate links are reduced. The operator only needs to pay attention to the reading of the weighing sensor to immediately know the actual weight of the waste oil in the material box, without complex calculations or additional corrections. Moreover, the hanging plate connecting plate is composed of a vertical plate and a horizontal plate, with a simple structure and good shape stability even when bearing a large load, which also greatly extends the service life of the equipment, reduces the maintenance frequency and cost, and ensures the economic benefits and social responsibilities under long-term operation.

[0008] The purpose of the present utility model is achieved through the following technical solutions:

[0009] A fixed bucket position lifting mechanism includes a lifting power unit, two hanging plate assemblies connected to the lifting power unit, and a material box connected to the two hanging plate assemblies. The hanging plate assembly includes a sensor support connected to the lifting power unit, a weighing sensor located above the sensor support and connected to the sensor support, and a hanging plate connecting plate located above the weighing sensor and connected to the weighing sensor. The hanging plate connecting plate is connected to the material box. The hanging plate connecting plate includes a vertical plate and a horizontal plate connected to the vertical plate. The weighing sensor is in contact connection with the lower surface of the horizontal plate.

[0010] Traditional waste collection systems often sacrifice measurement accuracy due to complex force transmission links. In contrast, this mechanism effectively shortens the force transmission distance by directly contacting the horizontal plate of the hanging plate connecting plate with the weighing sensor, reducing the errors that may be introduced in the intermediate links. This means that even in the case of small weight changes, it can quickly capture and accurately feedback, providing a solid foundation for subsequent data analysis and decision-making.

[0011] The hanging plate connecting plate is composed of a vertical plate and a horizontal plate, with a simple structure and good shape stability even when bearing a large load, which also greatly extends the service life of the equipment, reduces the maintenance frequency and cost, and ensures the economic benefits and social responsibilities under long-term operation.

[0012] Thanks to the direct-through force transmission design, the operator only needs to pay attention to the reading of the weighing sensor to immediately know the actual weight of the waste oil in the material box, without complex calculations or additional corrections. Such a design greatly simplifies the operation process, improves the work efficiency of on-site staff, and also reduces the possibility of human errors.

[0013] Although focused on the measurement of waste oil, the fixed bucket position lifting mechanism actually has a wide range of applications due to its general structural design. Whether it is the collection of fried waste oil in the food processing industry or the management of liquid waste in chemical enterprises, it can be seamlessly connected, demonstrating strong application potential.

[0014] Preferably, a supporting surface is provided on the top of the sensor support, and the weighing sensor is contact-connected to the supporting surface.

[0015] A flat and solid support surface is specially set on the top of the sensor holder to carry the weighing sensor. This design is not only a manifestation of physical support, but also ensures that the weighing sensor can operate on a level and stable platform, minimizing measurement errors and laying the foundation for high-precision weight readings. The flat support surface allows the weighing sensor to evenly distribute the pressure from the material box when it contacts it, avoiding local excessive force that damages the sensor or produces nonlinear response, which is crucial to maintaining long-term measurement accuracy.

[0016] Preferably, the sensor support is dug with a plurality of first fixing holes, screws are locked in the first fixing holes, and the sensor support is fastened to the lifting power unit by the screws.

[0017] The sensor support and the lifting power unit are firmly connected through the pre-designed first fixing hole and screw locking method. This hard connection not only greatly enhances the overall rigidity of the mechanism, but also effectively resists the influence of external vibration, ensuring the relative position of each component is stable under long-term and high-intensity use, avoiding loosening or falling off, thereby maintaining the continuity and safety of system operation. The use of standardized screws and preset fixing holes makes the assembly of the sensor support and the lifting power unit simple and quick, which not only saves installation time, but also reduces the potential error rate by reducing the need for manual adjustment, thereby improving the assembly quality of the entire system and the stability of initial operation.

[0018] Preferably, the sensor support is further provided with a plurality of second fixing holes, screws are locked into the second fixing holes, and the sensor is fastened to the sensor support by means of the screws.

[0019] The load cell is connected to the sensor holder via screws in the second fixing hole, which makes it very convenient when the load cell needs to be regularly inspected, cleaned or replaced. Disassembly with just a few screws not only speeds up the maintenance process, but also maintains a high level of functional integrity throughout the product life cycle because no permanent fixings need to be destroyed.

[0020] Preferably, the sensor holder has a triangular prism shape.

[0021] The choice of the triangular prism design as the basic contour of the sensor support is by no means accidental. The triangular prism shape exhibits extremely high structural stability in three-dimensional space. The three side faces and the bottom surface form a three-dimensional framework that can maintain its rigidity and integrity under lateral, longitudinal, and even oblique external forces, effectively resisting the risk of deformation. This is particularly important in applications involving precise measurement, such as the weighing sensor in the fixed bucket position lifting mechanism. The geometric characteristics of the triangular prism determine its excellent force transmission performance. Compared with other shapes, the triangular prism can disperse the pressure from the upper hanging plate connecting plate and the material box more evenly, avoiding measurement errors caused by stress concentration. In addition, its unique angle and corner transition treatment help reduce friction losses during force conduction, ensuring the purity and authenticity of the weighing signal.

[0022] Preferably, the vertical plate and the horizontal plate are integrally connected.

[0023] The integrated connection design of the vertical plate and the horizontal plate, rather than the traditional welding or bolt fixing method, fundamentally eliminates potential connection weak points, significantly enhancing the overall rigidity and durability of the hanging plate connecting plate. The integrated forming process also ensures that there are no gaps between the two components, avoiding the risk of external impurities intrusion or corrosion, extending the service life of the component, and at the same time simplifying the assembly process, bringing convenience at the assembly level.

[0024] Preferably, the hanging plate connecting plate further includes a reinforcing rib, and the reinforcing rib is connected to the upper surface of the horizontal plate and integrally connected to the vertical plate and the horizontal plate.

[0025] The addition of the reinforcing rib further improves the load-bearing capacity of the hanging plate connecting plate. Through the synergistic effect with the vertical plate, a more robust composite structure is formed. In the face of abnormal loads or sudden impacts, it can provide additional support to prevent structural instability or deformation, ensuring the continuity and safety of the system operation. The evenly distributed reinforcing ribs are also beneficial for optimizing the weight distribution pattern on the horizontal plate. Especially when the material box is placed unevenly, it can help disperse the pressure and reduce the excessive single-point stress, avoiding unnecessary damage to the weighing sensor.

[0026] Preferably, a plurality of third fixing holes are drilled in the horizontal plate, and screws are locked in the third fixing holes. The horizontal plate is locked to the sensor by the screws.

[0027] By reserving multiple third fixing holes on the horizontal plate and using screws to lock it to the sensor, this design method not only simplifies the assembly process but also greatly improves the overall accuracy of the weighing system. The screw-locking method not only provides the strength required for mechanical connection but also ensures that there is no slack or movement between the sensor and the hanging plate connecting plate. Especially during long-term and frequent lifting operations, this stable connection can significantly reduce the impact of vibration and wear on the weighing system, extend the equipment life, and reduce maintenance costs.

[0028] Preferably, the vertical plate is provided with a screw-locking avoidance window corresponding to the position of the first fixing hole.

[0029] The screw-locking avoidance window provided on the vertical plate is an innovative idea proposed by the designer considering the convenience and efficiency in the actual assembly process. When connecting the sensor support to the lifting power unit, these windows allow the operator to use a screwdriver or other screw-locking equipment without worrying about interference with other structural components and directly align with the target area for locking actions. This seemingly minor modification can significantly save time and improve the overall production rhythm under large-scale mass production conditions. For daily maintenance or emergency troubleshooting, the existence of the screw-locking avoidance window is also of great significance. Maintenance technicians can quickly access all necessary fixing points without obstruction, perform inspection or replacement tasks, significantly shortening the downtime for maintenance and indirectly creating more production benefits for the enterprise.

[0030] Preferably, it further includes a magnet and a proximity switch that cooperate with each other. There are two proximity switches, which are installed at two different heights of the material box, and the magnet is installed on the lifting power unit.

[0031] By installing proximity switches at different heights of the material box and cooperating with the magnet on the lifting power unit, this set of combinations injects an intelligent soul into the fixed-barrel-position lifting mechanism. When the magnet moves with the lifting power unit to a specific height, the proximity switch can immediately sense and trigger corresponding instructions, automatically stop lifting or emit a warning signal, realizing the automated control of the material loading and unloading process. This intelligent monitoring method not only greatly improves work efficiency but also significantly reduces the possibility of human misoperation, enhancing the safety and stability of the system.

[0032] A kitchen waste truck includes the fixed-barrel-position lifting mechanism as described above.

[0033] The beneficial effects of the present utility model compared with the prior art are:

[0034] The fixed barrel lifting mechanism of this utility model effectively shortens the force transmission distance and reduces the error that may be introduced in the intermediate links by directly contacting the horizontal plate of the hanging plate connecting plate with the weighing sensor. This means that even in the case of slight weight changes, it can be quickly captured and accurately fed back, providing a solid foundation for subsequent data analysis and decision-making.

[0035] The hanging plate connecting plate is composed of vertical plates and horizontal plates. It has a simple structure and can maintain good shape stability when bearing large loads. It also greatly extends the service life of the equipment, reduces maintenance frequency and costs, and ensures economic benefits and social responsibilities under long-term operation.

[0036] Thanks to the straight-through force transmission design, operators only need to pay attention to the reading of the weighing sensor to immediately know the actual weight of the waste grease in the material box without complicated calculations or additional corrections. This design greatly simplifies the operation process, improves the work efficiency of on-site staff, and also reduces the possibility of human error.

[0037] Although it focuses on the metering of waste oil, the fixed barrel lifting mechanism actually has a wide range of applications due to its universal structural design. Whether it is the collection of waste frying oil in the food processing industry or the management of liquid waste in chemical companies, it can be seamlessly connected and shows great application potential.

[0047] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0048] The technical solutions in this application will be described below with reference to the accompanying drawings.

[0049] This embodiment provides a fixed barrel position lifting mechanism, including a lifting power unit 100, two hanging plate assemblies 200 connected to the lifting power unit 100, and a material box 300 connected to the two hanging plate assemblies 200. The hanging plate assembly 200 includes a sensor support 210 connected to the lifting power unit 100, a weighing sensor 220 located above the sensor support 210 and connected to the sensor support 210, and a hanging plate connection plate 230 located above the weighing sensor 220 and connected to the weighing sensor 220. The hanging plate connection plate 230 is connected to the material box 300. The hanging plate connection plate 230 includes a vertical plate 231 and a horizontal plate 232 connected to the vertical plate 231. The weighing sensor 220 is in contact connection with the lower surface of the horizontal plate 232.

[0050] Traditional waste collection systems often sacrifice measurement accuracy due to complex force conduction links. In contrast, this mechanism effectively shortens the force conduction distance by directly contacting the cross plate 232 of the hanging plate connecting plate 230 with the load cell 220, reducing the errors that may be introduced in the intermediate links. This means that even in the case of minor weight changes, it can quickly capture and accurately feedback, providing a solid foundation for subsequent data analysis and decision-making.

[0051] The hanging plate connecting plate 230 is composed of a vertical plate 231 and a cross plate 232, with a simple structure and good shape stability even under large loads. It also greatly extends the service life of the equipment, reduces the maintenance frequency and cost, and ensures the economic benefits and social responsibilities under long-term operation.

[0052] Thanks to the direct-through force conduction design, the operator only needs to pay attention to the reading of the load cell 220 to immediately know the actual weight of the waste oil in the bin 300, without complex calculations or additional corrections. Such a design greatly simplifies the operation process, improves the work efficiency of on-site staff, and also reduces the possibility of human errors.

[0053] Although focused on the measurement of waste oil, this fixed-bin lifting mechanism actually has a wide range of applications due to its general structural design. Whether it is the collection of fried waste oil in the food processing industry or the management of liquid waste in chemical enterprises, it can be seamlessly connected, demonstrating strong application potential.

[0054] In this embodiment, a supporting surface 211 is provided at the top of the sensor support 210, and the load cell 220 is in contact connection with the supporting surface 211.

[0055] A flat and solid supporting surface 211 is specially provided at the top of the sensor support 210 for supporting the load cell 220. This design is not only a physical support, but more deeply, it ensures that the load cell 220 can operate on a horizontal and stable platform, minimizing measurement errors and thus laying the foundation for high-precision weight reading. The flat supporting surface 211 enables the load cell 220 to evenly distribute the pressure from the bin 300 when in contact, avoiding the situation where the sensor is damaged or produces non-linear response due to excessive local stress, which is crucial for maintaining long-term measurement accuracy.

[0056] In this embodiment, the sensor support 210 is provided with a plurality of first fixing holes 212, and screws are locked into the first fixing holes 212. The sensor support 210 is locked to the lifting power unit 100 by screws.

[0057] The sensor support 210 and the lifting power unit 100 are firmly connected by means of the pre-designed first fixing hole 212 and the screw locking method. This hard connection not only greatly enhances the overall rigidity of the mechanism, but also effectively resists the influence of external vibration, ensuring that the relative positions of the various components are stable under long-term, high-intensity use environments, avoiding loosening or falling off, thereby maintaining the continuity and safety of the system operation. The use of standardized screws and preset fixing holes makes the assembly of the sensor support 210 and the lifting power unit 100 simple and quick, which not only saves installation time, but also reduces the potential error rate by reducing the need for manual adjustment, thereby improving the assembly quality of the entire system and the stability of the initial operation.

[0058] In this embodiment, the sensor support 210 is further provided with a plurality of second fixing holes, screws are locked into the second fixing holes, and the sensor is fastened to the sensor support 210 by means of the screws.

[0059] The weighing sensor 220 is connected to the sensor holder 210 by screws in the second fixing hole. When it is necessary to regularly check, clean or replace the weighing sensor 220, the presence of the second fixing hole makes these operations extremely convenient. Disassembly can be completed with only a few screws, which not only speeds up the maintenance process, but also maintains a high level of functional integrity throughout the product life cycle because no permanent fixings need to be destroyed.

[0060] In this embodiment, the sensor holder 210 has a triangular prism shape.

[0061] It is no accident that the triangular prism design is chosen as the basic outline of the sensor holder 210. The triangular prism shape shows extremely high structural stability in three-dimensional space. The three-dimensional frame formed by its three sides and the bottom can maintain its rigidity and integrity under the action of lateral, longitudinal and even oblique external forces, and effectively resist the risk of deformation. This is especially important in occasions involving precision measurement, such as the application of weighing sensors 220 in fixed barrel lifting mechanisms. The geometric properties of the triangular prism determine that it has excellent force transmission performance. Compared with other shapes, the triangular prism can more evenly disperse the pressure from the upper hanging plate connecting plate 230 and the material box 300, avoiding measurement deviations caused by stress concentration. In addition, its unique angle and corner transition treatment helps to reduce friction losses during force transmission and ensure the purity and authenticity of the weighing signal.

[0062] In this embodiment, the vertical plate 231 and the horizontal plate 232 are integrally connected.

[0063] The vertical plate 231 and the horizontal plate 232 adopt an integrated connection design instead of the traditional welding or bolt fixing method, fundamentally eliminating potential weak connection points, significantly enhancing the overall rigidity and durability of the hanging plate connecting plate 230. The integrated forming process can also ensure that there are no gaps between the two components, avoiding the risk of external impurities intrusion or corrosion, extending the service life of the components, and at the same time simplifying the assembly process, bringing convenience at the assembly level.

[0064] In this embodiment, the hanging plate connecting plate 230 further includes a reinforcing rib 233, and the reinforcing rib 233 is connected to the upper surface of the horizontal plate 232 and integrally connected to the vertical plate 231 and the horizontal plate 232.

[0065] The addition of the reinforcing rib 233 further improves the load-bearing capacity of the hanging plate connecting plate 230. Through the synergistic effect with the vertical plate 231, a more robust composite structure is formed. When facing ultra-conventional loads or sudden impacts, it can provide additional support, prevent the structure from instability or deformation, and ensure the continuity and safety of the system operation. The uniformly distributed reinforcing ribs 233 are also beneficial to optimizing the weight distribution pattern on the horizontal plate 232. Especially when the material box 300 is placed unevenly, it can help disperse the pressure, reduce the situation of excessive single-point stress, and avoid unnecessary damage to the weighing sensor 220.

[0066] In this embodiment, a plurality of third fixing holes are drilled in the horizontal plate 232, and screws are locked in the third fixing holes. The horizontal plate 232 is locked to the sensor by screws.

[0067] By reserving a plurality of third fixing holes on the horizontal plate 232 and using screws to lock it to the sensor, this design method not only simplifies the assembly process, but also greatly improves the overall accuracy of the weighing system. The screw locking method not only provides the strength required for mechanical connection, but also ensures that there is no slack or movement between the sensor and the hanging plate connecting plate 230. Especially during long-term and frequent lifting operations, this stable connection can significantly reduce the impact of vibration and wear on the weighing system, extend the equipment life, and reduce the maintenance cost.

[0068] In this embodiment, a screw locking avoidance window 234 corresponding to the position of the first fixing hole 212 is drilled in the vertical plate 231.

[0069] The lock screw avoidance openings 234 provided on the vertical plate 231 are an innovative idea proposed by the designer considering the convenience and efficiency in the actual assembly process. When the sensor support 210 is connected to the lifting power unit 100, these openings allow the operator to use a screwdriver or other lock screw devices without worrying about interference between the screwdriver or other lock screw devices and other structural components, and directly align with the target area for locking actions. This seemingly minor modification can significantly save time and improve the overall production rhythm under large-scale mass production conditions. For daily maintenance or emergency fault troubleshooting, the existence of the lock screw avoidance openings 234 is also of great significance. Maintenance technicians can quickly access all necessary fixing points without obstruction to perform inspection or replacement tasks, significantly shortening the downtime maintenance time window and indirectly creating more production benefits for the enterprise.

[0070] In this embodiment, it further includes a magnet 400 and a proximity switch 500 that cooperate with each other. There are two proximity switches 500, and the two proximity switches 500 are installed at two different heights of the material box 300, and the magnet 400 is installed on the lifting power unit 100.

[0071] By installing proximity switches 500 at different heights of the material box 300 and cooperating with the magnet 400 on the lifting power unit 100, this combination injects an intelligent soul into the fixed barrel position lifting mechanism. When the magnet 400 moves with the lifting power unit 100 to a specific height, the proximity switch 500 can immediately sense and trigger corresponding instructions to automatically stop lifting or emit a warning signal, realizing the automated control of the material loading and unloading process. This intelligent monitoring method not only greatly improves work efficiency but also significantly reduces the possibility of human error, enhancing the safety and stability of the system.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
