Description

Technical Field

[0001] This utility model relates to the field of sanitation equipment technology, and in particular to a garbage transfer box. Background Technology

[0002] Currently, urban household waste is mostly transferred and transported using hook-lift trucks in conjunction with waste transfer containers. Waste transfer containers, as an important component of the sanitation hook-lift truck system, are widely used in the waste collection and transfer stages of horizontal waste compressors, pre-compression waste compression systems, and direct-compression waste treatment equipment.

[0003] In existing technologies, the doors of transfer containers typically employ a hinged structure directly connected to the container body. With prolonged opening and closing, the hinges are prone to jamming or even deformation, leading to rear door swaying and uneven stress, severely impacting opening smoothness and sealing performance. Furthermore, when open, the container door is positioned at the top of the container, hindering waste disposal. Additionally, most waste transfer containers rely on an onboard hydraulic system for opening the rear door. Specifically, operators must connect the container door cylinder to the hydraulic interface of the hooklift truck, supplying oil to the cylinder via an oil pipe to drive the rear door open or close—a cumbersome operation. Summary of the Invention

[0004] Therefore, this utility model provides a garbage transfer container that improves the stability and convenience of opening and closing the flip door.

[0005] To solve the above-mentioned technical problems, this utility model provides a waste transfer container, comprising: Box; Two sets of drive devices are symmetrically arranged on the left and right sides of the housing. Each set of drive devices includes a hydraulic cylinder, a lower push arm, and an upper push arm arranged on the corresponding side of the housing. The lower push arm has a rotating part rotatably connected to the side of the housing between its front end and rear end. The hydraulic cylinder is rotatably connected to the side of the housing and its drive end is rotatably connected to the rear end of the lower push arm. The rear end of the upper push arm is rotatably connected to the side of the housing. A flip door is movably installed at the opening at the front end of the housing. The side ends of the flip door are rotatably connected to the front ends of the lower push arm and the upper push arm, respectively, and can be flipped to the top of the housing under the drive of the drive device. The enclosure is also equipped with a control cabinet, a hydraulic station mounting cabinet, and a solar panel assembly. The control cabinet is electrically connected to the hydraulic station mounting cabinet and the solar panel assembly, respectively. The hydraulic station mounting cabinet is connected to the hydraulic cylinder.

[0006] In one embodiment of this utility model, the flip door includes two angled folding plates, and the front ends of the lower push arm and the upper push arm are respectively rotatably connected to the lower and upper parts of the flip door.

[0007] In one embodiment of this utility model, the push arm has a curved structure, including a first connecting arm and a second connecting arm arranged at an angle and connected to each other, the rotating part is disposed at the connection between the first connecting arm and the second connecting arm, the driving end of the hydraulic cylinder is hinged to the first connecting arm, the second connecting arm is hinged to the flip door, and the length of the first connecting arm is less than the length of the second connecting arm.

[0008] In one embodiment of this utility model, the rear end of the upper push arm forms a first upper hinge point with the side end of the box, so that it swings around the point. The front end of the upper push arm forms a second upper hinge point with the side end of the flip door. The upper push arm is used to apply a pulling or pushing force to the upper part of the flip door so that the flip door maintains a stable posture throughout the entire rotation process. The rear end of the first connecting arm forms a first lower hinge point with the driving end of the hydraulic cylinder; the rotating part forms a second lower hinge point with the side end of the housing; the front end of the second connecting arm forms a third lower hinge point with the side end of the flip door. When the hydraulic cylinder swings, it drives the push arm to swing around the second lower hinge point, thereby driving the flip door to rotate.

[0009] In one embodiment of this utility model, a rear cover plate is provided at the rear end of the box, the control cabinet and hydraulic station installation cabinet are embedded in the rear cover plate, and the solar panel assembly is installed at the top of the box.

[0010] In one embodiment of this utility model, the hydraulic station mounting cabinet includes a first cabinet body, a first cabinet door that cooperates with the first cabinet body, and a hydraulic station disposed in the first cabinet body; the control cabinet includes a second cabinet body, a second cabinet door that cooperates with the second cabinet body, and a controller and a storage battery disposed in the second cabinet body. The controller is electrically connected to the solar panel assembly, the storage battery, and the hydraulic station respectively, and the storage battery is electrically connected to the hydraulic station.

[0011] In one embodiment of this utility model, casters are provided at the bottom of the box.

[0012] In one embodiment of this utility model, a pull arm hook is provided on the rear cover plate.

[0013] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a waste transfer container with a dual-sided linkage mechanism formed by hydraulic cylinders, a lower push arm, and an upper push arm arranged on the left and right sides of the container body, respectively acting on the upper and lower parts of the tilting door. This controls the movement trajectory of the tilting door throughout the opening and closing process, eliminating the swaying, twisting, or force concentration caused by single-sided drive. This significantly improves the smoothness of the door's movement and the reliability of its sealing, and allows the tilting door to tilt to the top of the container without obstructing the opening. The container integrates a hydraulic station mounting cabinet, a control cabinet, and a solar panel assembly. Under sufficient sunlight, the solar panel assembly provides the main power to the system by charging the battery. Under insufficient sunlight or prolonged cloudy / rainy conditions, the battery independently supplies power to the controller and hydraulic station, ensuring that the opening and closing of the tilting door is unaffected. There is no need to supply oil through the hooklift truck's oil pipe, avoiding cumbersome pipe insertion, oil leakage, interface contamination, and safety hazards caused by incorrect pipe connections, greatly improving operational convenience and system reliability. The control cabinet and hydraulic station mounting cabinet are both embedded in the rear cover of the container, resulting in a compact layout and easier maintenance. Attached Figure Description

Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0028] Reference Figures 1 to 3As shown, a waste transfer container of this utility model includes: Box 1; Two sets of drive devices 2 are symmetrically arranged on the left and right sides of the housing 1. Each set of drive devices 2 includes a hydraulic cylinder 21, a lower push arm 22, and an upper push arm 23 arranged on the corresponding side of the housing 1. The lower push arm 22 has a rotating part rotatably connected to the side of the housing 1 between its front end and rear end. The hydraulic cylinder 21 is rotatably connected to the side of the housing 1 and its drive end is rotatably connected to the rear end of the lower push arm 22. The rear end of the upper push arm 23 is rotatably connected to the side of the housing 1. A flip door 3 is movably installed at the opening at the front end of the housing 1. The side ends of the flip door 3 are rotatably connected to the front ends of the lower push arm 22 and the upper push arm 23, respectively, and can be flipped to the top of the housing 1 by the drive device 2 (see reference). Figure 6 ), will not block the opening of container 1 when garbage is disposed of; The housing 1 is also equipped with a control cabinet 4, a hydraulic station mounting cabinet 5, and a solar panel assembly 6. The control cabinet 4 is electrically connected to the hydraulic station mounting cabinet 5 and the solar panel assembly 6, respectively. The hydraulic station mounting cabinet 5 is connected to the hydraulic cylinder 21 (through a hydraulic oil circuit).

[0029] In one embodiment, the flip door 3 includes two angled folding plates 31, and the front ends of the lower push arm 22 and the upper push arm 23 are respectively rotatably connected to the lower and upper parts of the flip door 3.

[0030] In one embodiment, the push arm 22 has a curved structure, including a first connecting arm 221 and a second connecting arm 222 arranged at an angle and connected to each other. The rotating part is disposed at the connection between the first connecting arm 221 and the second connecting arm 222. The driving end of the hydraulic cylinder 21 is hinged to the first connecting arm 221, and the second connecting arm 222 is hinged to the flip door 3. The length of the first connecting arm 221 is less than the length of the second connecting arm 222.

[0031] In one embodiment, the rear end of the upper push arm 23 forms a first upper hinge point 24 with the side end of the housing 1, so that it swings around the point. The front end of the upper push arm 23 forms a second upper hinge point 25 with the side end of the flip door 3. The upper push arm 23 is used to apply a pulling or pushing force to the upper part of the flip door 3 so that the flip door 3 maintains a stable posture throughout the entire rotation process. The rear end of the first connecting arm 221 forms a first lower hinge point 26 with the driving end of the hydraulic cylinder 21; the rotating part forms a second lower hinge point 27 with the side end of the housing 1; the front end of the second connecting arm 222 forms a third lower hinge point 28 with the side end of the flip door 3. When the hydraulic cylinder 21 swings, it drives the push arm 22 to swing around the second lower hinge point 27, thereby driving the flip door 3 to rotate.

[0032] In one embodiment, both the lower push arm 22 and the upper push arm 23 are plate-type rods.

[0033] In one embodiment, a rear cover plate 7 is provided at the rear end of the housing 1, the control cabinet 4 and the hydraulic station installation cabinet 5 are embedded in the rear cover plate 7, and the solar panel assembly 6 is installed at the top of the housing 1.

[0034] In one embodiment, refer to Figures 4 to 5 As shown, the hydraulic station mounting cabinet 5 includes a first cabinet 51, a first cabinet door 52 that cooperates with the first cabinet 51, and a hydraulic station 53 disposed within the first cabinet 51; the control cabinet 4 includes a second cabinet 41, a second cabinet door 42 that cooperates with the second cabinet 41, and a controller 43 and a battery 44 disposed within the second cabinet 41. The controller 43 is electrically connected to the solar panel assembly 6, the battery 44, and the hydraulic station 53, respectively, and the battery is electrically connected to the hydraulic station 53.

[0035] By installing a hydraulic station mounting cabinet 5 and a control cabinet 4 on the housing 1, the hydraulic station 53 provides pressurized oil to the hydraulic cylinder 21, and the controller 43 in the control cabinet 4 processes the opening and closing commands (issued by the remote control) and is powered by the storage battery 44. Under sufficient sunlight conditions, the solar panel assembly 6 provides the main power to the system by charging the storage battery 44. Under insufficient sunlight or prolonged cloudy or rainy conditions, the storage battery 44 independently supplies power to the controller 43 and the hydraulic station 53, ensuring that the opening and closing of the tilting door 3 is not affected.

[0036] Specifically, the input terminals of the controller 43 are electrically connected to the solar panel assembly 6 and the battery 44, respectively, for real-time detection of the output voltage and current of the solar panel assembly 6 and the remaining charge status of the battery 44. The controller 43 automatically switches the charging mode according to the light intensity and the charge status of the battery 44, so that the solar panel assembly 6 charges the battery 44 with constant voltage or constant current. Under conditions of no light or insufficient light, the controller 43 controls the battery 44 to enter the discharge mode, providing stable DC power to the hydraulic station 53 in the hydraulic station mounting cabinet 5.

[0037] It should be noted that the solar panel module 6 uses a monocrystalline silicon solar panel. The charging process of the battery 44 through the solar panel module 6 and the power management through the controller 43 are existing technologies and will not be described in detail here.

[0038] Specifically, when the second cabinet 41 is closed, the working status of the controller can be directly observed through the transparent observation window 45 provided on the second cabinet 41.

[0039] Specifically, the controller 43 adopts a programmable logic controller (PLC) or an industrial-grade embedded controller, and is a control module with hydraulic control functions.

[0040] Furthermore, considering that during prolonged rainy seasons such as the plum rain season, there may be insufficient power due to continuous reliance on the battery 44 for power supply, which could affect the opening and closing of the tilting door 3 or even prevent the small hydraulic station 53 from starting, multiple safety measures can be pre-configured on the controller 43 to achieve status warning and risk prevention: First, when the battery 44 is low on power, it will automatically issue a power warning three days before it is expected to run out; second, the system will simultaneously output an audible alarm; and third, a "Warning" message will be displayed in a prominent position to remind operators to handle the situation in a timely manner and ensure the reliable operation of the system.

[0041] In one embodiment, casters 11 are provided at the bottom of the housing 1.

[0042] In one embodiment, the rear cover plate 7 is provided with a hook arm hook 71. It is compatible with existing models of hook arm trucks.

[0043] It should be noted that, referring to Figures 6 to 8 As shown, when the hydraulic cylinder 21 extends, its driving force is transmitted to the rotating part through the first connecting arm 221, and then the second connecting arm 222 pushes the lower part of the tilting door 3 to pivot around the side end of the housing 1. At the same time, the upper push arm 23, with the side end of the housing 1 as the upper hinge point, applies a synchronous pulling and pushing force to the upper part of the tilting door 3 during its rotation, so that the tilting door 3 maintains a stable posture throughout the movement, avoiding deformation or jamming caused by single-point drive. The symmetrical arrangement of the two sets of drive devices ensures that the forces on the left and right sides are consistent, guaranteeing the smooth rotation of the tilting door 3 as a whole.

[0044] The waste transfer container adopts a hybrid power supply method, using a combination of solar energy and battery 44 to provide stable power to the vehicle's small hydraulic station 53 and electronic control system. By integrating the hydraulic station 53, solar panel assembly 6, and battery 44 onto the waste transfer container, the opening and closing of the tilting door 3 is mainly achieved by solar energy on sunny days; in cloudy or rainy weather or when there is insufficient sunlight, the battery 44 provides supplementary power to ensure that the tilting door 3 can open and close normally.

[0045] The workflow is as follows: The waste transfer container (via a tilting mechanism) is tilted 90° so that the tilting door 3 faces upward. A command is sent via remote control, and controller 43 activates hydraulic station 53 to open the tilting door 3. An externally mounted material hopper is then inserted vertically into the waste transfer container to begin discharging waste. After discharging is complete, the tilting door 3 is closed again via remote control. These opening and closing actions can be performed at any time as needed, significantly improving operational convenience and work efficiency.

[0046] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
