Description

Technical Field

[0001] This utility model relates to the field of garbage dumping technology, specifically a garbage dumping device for sanitation vehicles. Background Technology

[0002] With the acceleration of urbanization, efficient collection and transportation of household waste has become a core aspect of sanitation work. Traditional garbage trucks typically use fixed hooks or chain lifting mechanisms, requiring manual hooking of garbage bins onto the lifting arm. This is physically demanding and poses safety hazards, such as the garbage bin falling if the hook detaches. Furthermore, when not in operation, the existing lifting arm and load-bearing mechanism protrude from the vehicle body, occupying a large space and increasing the risk of collisions with pedestrians or vehicles, especially when operating in narrow alleys where flexibility is insufficient.

[0003] Some improved solutions achieve automatic clamping through hydraulic drive, but they have the following drawbacks: 1. The clamping mechanism and the lifting mechanism are controlled independently, requiring two sets of power systems, which are complex and energy-intensive; 2. The trash can lacks anti-swaying restrictions during the flipping process, and the trash can is prone to spillage due to the shift of the center of gravity; 3. The support plate cannot be folded for storage, which takes up a lot of space.

[0004] Therefore, a garbage dumping device for sanitation vehicles is needed to improve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a garbage dumping device for sanitation vehicles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a garbage dumping device for a sanitation vehicle, comprising a main plate, support arms fixedly provided on both sides of the main plate, a sliding rod slidably provided inside the support arm, a rotating lifting plate rotatably provided on the inner side of one end of the sliding rod, the main plate being hinged to the vehicle body, and a hydraulic cylinder being hinged to the surface of the main plate, the other end of the hydraulic cylinder being hinged to the vehicle body.

[0007] As a preferred embodiment of this utility model, a support block is fixedly provided at the end of the slide rod, and the support block is in close contact with the lower surface of the rotating lifting plate.

[0012] As a preferred embodiment of this utility model, the inner side of the support arm is provided with a through groove, through which the connecting rod passes and is slidably disposed within the through groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves linkage control of the clamping bin edge and the lifting slide rod moving the garbage bin upward by synchronously driving the lead screw one and lead screw two with a single motor, thereby reducing the number of power sources, simplifying the structure, reducing energy consumption, and improving operating efficiency.

[0015] 2. The hydraulic cylinder of this utility model retracts to make the device horizontal, the slide bar is fully retracted into the support arm, the baffle plate presses against the extension of the rotating lifting plate, forcing the bearing part to rotate and stand up, which significantly reduces the lateral space occupied by the vehicle body and avoids pedestrian collisions or vehicle scrapes; at the same time, it prevents the rotating lifting plate from rusting or deforming due to long-term exposure.

[0016] 3. The L-shaped pressure plate and the rotating lifting plate of this utility model form an upper and lower clamping structure, which restricts the shaking of the trash can during the lifting and flipping process and prevents the trash from spilling; the support block supports the bearing part of the rotating lifting plate to ensure the stability of the center of gravity of the trash can when flipping, which is especially suitable for large-capacity trash cans.

[0029] Please see Figure 1-7This utility model provides a technical solution: a garbage dumping device for a sanitation vehicle, including a main plate 5, with support arms 1 fixedly mounted on both sides of the main plate 5, and a sliding rod 7 slidably mounted inside the support arm 1. A rotating lifting plate 8 is rotatably mounted on the inner side of one end of the sliding rod 7. The main plate 5 is hinged to the vehicle body, and a hydraulic cylinder 15 is hinged to the surface of the main plate 5. The other end of the hydraulic cylinder 15 is hinged to the vehicle body. When the motor 13 starts, it drives the second lead screw 12 to rotate, which drives the second nut 14 and the connecting rod 3 to descend, so that the pressure plate 4 presses down to tighten the edge of the garbage can. At the same time, the first lead screw 11 rotates synchronously, which drives the sliding rod 7 to slide upward along the support arm 1 through the first nut 10, clamping the garbage can. When the sliding rod 7 rises to a preset height, the hydraulic cylinder 15 extends, pushing the main plate 5 to flip upward around the hinge point of the vehicle body. The garbage can tilts with the rotating lifting plate 8, and the garbage slides down due to gravity.

[0030] As an example of this utility model, a support block 9 is fixedly provided at the end of the slide bar 7, and the support block 9 is in close contact with the lower surface of the rotating lifting plate 8.

[0031] As an example of this utility model, the rotating lifting plate 8 is rotatably mounted inside the slide rod 7 via a rotating shaft. The rotating lifting plate 8 is divided into a front bearing part and a rear extension part by the rotating shaft. A baffle 6 is fixedly provided at the lower end of the main body plate 5. The baffle 6 is arranged vertically and vertically with the extension part of the rotating lifting plate 8. The main body plate 5 is fixed to the vehicle body by a hinge. The hydraulic cylinder 15 retracts to make the device horizontal. The slide rod 7 is completely retracted into the support arm 1. At this time, since the baffle 6 presses against the extension part of the rotating lifting plate 8, the rotating lifting plate 8 rotates and stands upright, reducing the occupied area and preventing injury.

[0032] As an example of this utility model, a motor 13 is fixedly installed at the upper end of the support arm 1, a lead screw 12 is fixedly installed at the output end of the motor 13, and a lead screw 11 is fixedly installed at one end of the lead screw 12.

[0033] As an example of this utility model, a nut 10 is fixedly provided inside the slide bar 7, and the nut 10 is threadedly connected to the lead screw 11.

[0034] As an example of this utility model, the screw rod 12 is threadedly connected to a nut 14. The nuts 14 on both sides are fixed by a connecting rod 3, and a pressure plate 4 is fixedly provided on the surface of the connecting rod 3. The pressure plate 4 is L-shaped. When the motor 13 starts, it drives the screw rod 12 to rotate, which in turn drives the nuts 14 and the connecting rod 3 to rise. At the same time, the screw rod 11 is coaxially fixed and rotates synchronously with the screw rod 12. The nut 10 drives the slide rod 7 to slide down along the support arm 1. At this time, the baffle 6 no longer presses against the extension of the rotating lifting plate 8. Under the action of gravity, the rotating lifting plate 8 rotates and unfolds, falling onto the support block 9. At this time, the garbage can is placed on the bearing part of the rotating lifting plate 8.

[0035] As an example of this utility model, the inner side of the support arm 1 is provided with a through groove 2, and the connecting rod 3 passes through and is slidably disposed inside the through groove 2.

[0036] Working principle: When in use, the main plate 5 is fixed to the vehicle body by hinge. The hydraulic cylinder 15 retracts to make the device horizontal. The slide bar 7 is fully retracted into the support arm 1. At this time, because the baffle 6 presses against the extension of the rotating lifting plate 8, the rotating lifting plate 8 rotates and stands up, reducing the area occupied and preventing injury.

[0037] When motor 13 starts, it drives lead screw 12 to rotate, which in turn drives nut 14 and connecting rod 3 to rise. At the same time, lead screw 11 and lead screw 12 are coaxially fixed and rotate synchronously. Through nut 10, slide rod 7 slides down along support arm 1. At this time, baffle 6 no longer presses against the extension of rotating lifting plate 8. Under the action of gravity, rotating lifting plate 8 rotates and unfolds, falling on support block 9. At this time, the garbage can is placed on the bearing part of rotating lifting plate 8.

[0038] At this time, motor 13 starts, driving lead screw 12 to rotate, which in turn drives nut 14 and connecting rod 3 to descend, causing pressure plate 4 to press down on the edge of the garbage can. At the same time, lead screw 11 rotates synchronously, driving slide rod 7 to slide upward along support arm 1 through nut 10, clamping the garbage can. When slide rod 7 rises to the preset height, hydraulic cylinder 15 extends, pushing main plate 5 to flip upward around the hinge point of the vehicle body. The garbage can tilts with the rotating lifting plate 8, and the garbage slides down due to gravity.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
