Description

Technical Field

[0001] This application relates to the field of garbage truck technology, specifically to a garbage truck bin-holding device. Background Technology

[0002] The garbage truck's bin-lifting device is a core attachment of modern sanitation vehicles. Through a combination of hydraulic cylinders and a sprocket and chain mechanism, it lifts, tilts, and resets standard garbage bins, aiming to replace traditional manual handling and improve collection efficiency. During the lifting process, the bottom support plate and the rear baffle work together to stabilize the bin and prevent slippage and tipping.

[0003] However, this device reveals significant shortcomings when faced with the increasingly common standard of hygiene features like covered trash cans: its mechanical gripper design only accommodates the contours of the can. During emptying, the lid often droops due to gravity or collides with the lifting frame, preventing it from fully opening. This results in some trash being trapped inside, requiring manual cleaning. More seriously, the movable lid is prone to rigid collisions with the device during the robotic arm's movement, causing not only deformation or breakage of the lid hinges but also potential damage to the device's sensors and hydraulic lines. After completing the task, the device can only reset the trash can, failing to automatically close the open lid. This allows odors to escape directly and attracts flies and mosquitoes, damaging community hygiene and contradicting the original intention of using covered trash cans to improve public health.

[0004] Therefore, this application proposes a garbage truck bin-holding device that can limit the bin lid by modifying the gripper and adding a lid opening limit device, and automatically close the lid after dumping. Utility Model Content

[0009] One end of the chain is bolted to the vehicle body, and the other end is hinged to the lower part of the inner frame. The middle part of the chain is connected to the sprocket drive.

[0010] Two sets of bucket-holding rods are slidably set on the upper end of the outer frame. One end of the bucket-holding rod is threadedly connected to a driver, and the end of the bucket-holding rod away from the outer frame is rotatably connected to a lid flipper.

[0011] The bucket-holding rod limits the position of the trash can through relative movement. The lid-flipping device inserts into the lower part of the lid during the movement of the bucket-holding rod and limits the lid. The lid-flipping device opens and limits the lid by flipping. The hydraulic cylinder push rod drives the chain to lift the inner frame, so that the inner frame clamps the bucket body with the outer frame and lifts it for dumping.

[0012] The trash can is secured by a gripping rod, and the lid flipper is inserted under the lid during the gripping process. The lid flipper clamps the lid, and then flips the lid to rotate and limit its rotation. After emptying, the lid flipper closes the lid, effectively preventing the lid from colliding with the device and causing damage. It also prevents the trash can from opening after emptying, thus avoiding attracting insects or emitting odors.

[0013] Furthermore, four sets of rollers are installed on the side of the outer frame near the vehicle body. The two lower sets of rollers are rotatably connected to the side wall of the inner frame so that the inner frame can be flipped after being raised to a certain height. A lower clamping plate is fixedly installed in the middle of the inner frame, and an upper clamping plate is welded and fixed to the upper end of the outer frame to hold the edge of the trash can during the rising process.

[0017] The threaded rod is rotatably connected to the inner wall of the upper plate, with one end plugged into the output end of the drive motor. The threads on both sides of the center of the threaded rod are in opposite directions.

[0018] The threaded sleeve has two sets of threads with opposite directions, which are respectively threaded to both sides of the threaded rod. The side of the threaded sleeve is welded and fixed to the barrel rod.

[0019] Furthermore, the flip cover includes:

[0020] The rotating motor is bolted to the side of the bucket-holding rod away from the vehicle body, and a swing arm is plugged into the output end of the rotating motor.

[0021] The rear end of the cover-opening rod is welded and fixed to the end of the swing arm away from the rotating motor, and the end of the cover-opening rod has a trapezoidal structure.

[0022] The limiting rod is slidably connected to the cover opening rod. At the same time, the limiting rod is spring-connected to the cover opening rod so that the limiting rod and the cover opening rod move closer to each other. The sliding connection between the limiting rod and the cover opening rod is equipped with a limit so that the limiting rod can move along the length direction of the cover opening rod.

[0023] Compared with existing technologies, it has the following beneficial effects:

[0024] This utility model provides a garbage truck bin-holding device. The garbage bin is fixed by a bin-holding rod, and a flip-top device is inserted into the lower edge of the bin lid during the bin-holding process, so that the flip-top device clamps the bin lid.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 4 As shown, this utility model provides the following technical solution: a garbage truck bin-holding device; comprising:

[0032] The main body 1 of the bucket holder is mainly composed of an outer frame 11 and an inner frame 12. The inner frame 12 is slidably connected to the outer frame 11 on both sides. The sliding connection is limited by the sliding of the slide rail 113 to prevent the inner frame 12 from coming out of the outer frame 11. The inner frame 12 is positioned inside the outer frame 11.

[0033] The lower end of the hydraulic cylinder push rod 2 is bolted to the vehicle body, and the output end is equipped with a sprocket 3. The hydraulic cylinder push rod 2 is connected to the electrical signal of the control system inside the vehicle body. Alternatively, a controller can be installed on the side of the hydraulic cylinder push rod 2 so that the operator can operate it from the side of the vehicle body.

[0034] Chain 4 is bolted to the vehicle body at one end and hinged to the lower part of the inner frame 12 at the other end. The middle part of chain 4 is connected to the sprocket 3 for transmission.

[0035] Two sets of bucket-holding rods 5 are slidably set on the upper end of the outer frame 11. One end of the bucket-holding rod 5 is threadedly connected to a driver 6, and the end of the bucket-holding rod 5 away from the outer frame 11 is rotatably connected to a flip-top device 7.

[0036] The bucket holding rod 5 limits the garbage can through relative movement. The lid flipper 7 inserts into the lower part of the lid and limits the lid during the movement of the bucket holding rod 5. The lid flipper 7 opens and limits the lid by flipping. The hydraulic cylinder push rod 2 drives the chain 4 to lift the inner frame 12, so that the inner frame 12 clamps the garbage body with the outer frame 11 and lifts it for dumping.

[0037] See Figure 2 The outer frame 11 has four sets of rollers 111 near the vehicle body. The two lower sets of rollers 111 are rotatably connected to the side wall of the inner frame 12, so that the inner frame 12 can be lifted to a certain height and then flipped. When the output end of the hydraulic cylinder push rod 2 moves upward, it drives the inner frame 12 to move upward through the chain 4. During the upward movement, the inner frame 12 contacts the edge of the bucket and clamps the edge of the bucket together with the outer frame 11. Then, it synchronously drives the bucket and the outer frame 11 to rise. During the upward movement of the outer frame 11, the rollers 111 roll and move on the side of the vehicle body or on the set track to slide and reduce friction.

[0038] See Figure 1 The inner frame 12 has a lower clamping plate 121 fixedly installed in the middle, and the outer frame 11 has an upper clamping plate 112 welded and fixed at the upper end to clamp the edge of the trash can during the upward movement.

[0039] See Figure 1 The lower part of the inner frame 12 is also provided with a pad plate 122, and the lower clamping plate 121 is connected to the lower end of the inner frame 12 by a spring.

[0040] After the barrel is raised to a certain height, the lower clamping plate 121 is in a restricted position and flips, causing the barrel to rotate and tilt. After tilting is completed, the hydraulic cylinder push rod 2 moves in the opposite direction, causing the inner frame 12 and the outer frame 11 to return to the initial position.

[0041] See Figure 1 A fixing plate 21 is provided in the middle of the cylinder push rod 2, and the cylinder push rod 2 is bolted to the vehicle body through the fixing plate 21.

[0042] As another embodiment, such as Figure 1 , Figure 3 as well as Figure 4 As shown, a slide rail 113 is provided on the side of the upper plate 112, and the bucket-holding rod 5 is slidably connected to the upper plate 112 through the slide rail 113.

[0043] Two sets of bucket-holding rods 5 are slidably connected to both sides of the upper plate 112. By sliding, the distance between the two sets of bucket-holding rods 5 can be changed, thereby adapting to trash cans of different widths and sizes.

[0044] See Figure 3 Driver 6 includes:

[0045] The drive motor 61 is bolted to the side of the upper clamping plate 112, and the output end of the drive motor 61 extends through the upper clamping plate 112 into its interior; wherein, the drive motor 61 is a forward and reverse reversible motor, and the spacing between the bucket-holding rods 5 is controlled by the forward and reverse rotation of the drive motor 61.

[0046] The threaded rod 62 is rotatably connected to the inner wall of the upper clamping plate 112, and one end is plugged into the output end of the drive motor 61. The threads on both sides of the center of the threaded rod 62 are opposite in direction.

[0047] The threaded sleeve 63 has two sets of threads with opposite directions, which are respectively threaded to both sides of the threaded rod 62. The side of the threaded sleeve 63 is welded and fixed to the barrel clamping rod 5.

[0048] When bucket clamping is required, the drive motor 61 drives the threaded rod 62 to rotate. Since the threads on both sides of the threaded rod 62 are in opposite directions, the two sets of threaded sleeves 63 are driven to move relative to each other, and at the same time drive the bucket clamping rod 5 to slide, that is, to move closer or further away from each other. At the same time, the self-locking property of the threads is used to lock them. The two sets of bucket clamping rods 5 complete the bucket clamping operation as they move closer to each other. It should be noted that since the bucket clamping rod 5 itself is provided with a limit in the sliding connection with the upper clamping plate 112, the threaded sleeve 63 will not deflect or rotate during the driving process. It can only move horizontally along the length direction of the threaded rod 62.

[0049] See Figure 1 as well as Figure 4 The flip cover 7 includes:

[0050] Rotary motor 71 is bolted to the side of the bucket arm 5 away from the vehicle body, and a swing arm 72 is plugged into the output end of rotary motor 71.

[0051] The lid-opening rod 73 is welded and fixed at its rear end to the end of the swing arm 72 away from the rotating motor 71. The end of the lid-opening rod 73 has a trapezoidal structure. When the bucket-holding rods 5 are driven to approach each other, the lid-opening rod 73 is inserted into the lower part of the bucket lid through the reminder structure at its front end and slightly opens the bucket lid.

[0052] The limiting rod 74 is slidably connected to the lid-opening rod 73. Simultaneously, the limiting rod 74 is spring-connected to the lid-opening rod 73, allowing them to approach each other. When the lid-opening rod 73 is inserted to the lower edge of the lid, the limiting rod 74 naturally adapts to the lid thickness via its front end's adjustment structure. The slidable connection with the lid-opening rod 73 causes them to move away from each other, stretching the spring. The spring's tension then clamps the lid between the lid-opening rod 73 and the limiting rod 74.

[0053] After clamping is completed, the rotating motor 71 rotates, driving the lid opening rod 73 and the limiting rod 74 to rotate, opening the lid and limiting it; preventing it from being displaced by external influences during the tilting process.

[0054] It should be noted that the sliding connection between the limiting rod 74 and the lid opening rod 73 is equipped with a limit, so that the limiting rod 74 can move along the length direction of the lid opening rod 73, while preventing the limiting rod 74 from coming off the lid opening rod 73; after the tilting operation is completed, the bucket returns to the initial position. At this time, the rotating motor 71 rotates and drives the limiting rod 74 to rotate and close the bucket lid. Finally, the bucket holding rods 5 move away from each other to release the clamp and drive the lid opening rod 73 to disengage from the bucket lid.

[0055] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
