Description

Technical Field

[0001] This utility model relates to the technical field of garbage bin docking devices, and in particular to an automatic tilting and docking device for garbage bins on urban streets. Background Technology

[0002] With the accelerating pace of urbanization, numerous trash cans have been installed in public areas such as city streets, communities, and parks for the temporary collection of household waste. In sanitation work, staff need to regularly collect and remove the trash from these cans. Currently, the commonly used method is manual or semi-automatic, where the trash cans are towed to the back of a garbage truck, and the trash is then manually or assisted by a dumping docking device to empty it into the truck.

[0003] While existing automatic dumping and docking devices for urban street garbage bins can achieve docking and basic dumping functions between the bins and the collection device, problems often arise in actual use, such as the bottom of the garbage bins being compacted or strong-adhesive garbage failing to completely detach. This is especially true when bagged or other wet garbage adheres to the inner wall or bottom of the bins, where the dumping action alone is often insufficient to completely empty them. Current docking devices typically lack an effective tapping mechanism, failing to provide auxiliary tapping during the dumping process. This results in the need for manual intervention to clean up residual garbage, reducing operational efficiency and increasing the workload of sanitation workers. Therefore, there is an urgent need for a docking device that can automatically tap and assist in unloading during the dumping process to improve the thoroughness and automation of garbage collection. Utility Model Content

A gravity block 9 is slidably connected to the inner wall of the slide 8, and an insert block 10 is fixedly connected to the top of the gravity block 9. Slide grooves 11 are opened on both sides of the insert block 10. A slider 12 is slidably connected inside each of the two slide grooves 11. The opposite ends of the two sliders 12 are both arc-shaped. A second spring 29 is fixedly connected to the side wall of each of the two sliders 12. One end of the second spring 29 is fixedly connected to the inner wall of the slide groove 11. A connecting hole 13 is opened between the top of the slide frame 1 and the inner wall of one end of the slide 8.

[0008] Preferably, the support plate 6 is L-shaped, and two second electric telescopic rods 23 for driving the toothed plate 7 to move upward are fixedly connected to the bottom of the support plate 6. An anti-fall plate 24 is fixedly connected to the top of the tilting plate 5.

[0013] The beneficial effects of this utility model are:

[0014] This automatic dumping and docking device for urban street trash cans features a striking mechanism that is linked to the dumping process. This mechanism automatically strikes the trash can during dumping, effectively solving the problem of compacted or adhered trash that is difficult to remove. A second electric telescopic rod drives a toothed plate to insert and lift the trash can, working in conjunction with an anti-drop plate for stable clamping. The first electric telescopic rod then raises the lifting frame, simultaneously driving the dumping plate to rotate and tilt within the L-shaped structure at the top of the chute frame, ensuring thorough dumping. During dumping, a second pulley presses down the insert block, releasing a gravity block. The gravity block drives the rack and gear to rotate, which in turn pulls the rope, causing an elliptical block to rotate. The elliptical block periodically lifts the rubber hammer and stretches the first spring. The spring's return action results in intermittent striking by the rubber hammer. This design requires no external drive and completes the striking action through its own structure. It is compact, reliable, and effectively vibrates the top of the trash can, promoting the smooth removal of trash and preventing it from adhering. This improves the thoroughness and efficiency of dumping, reduces the workload of sanitation workers, and is particularly suitable for improving the efficiency of urban street trash dumping.

[0028] like Figures 1 to 8 As shown, an automatic dumping and docking device for urban street trash cans includes a chute frame 1. A first electric telescopic rod 2 is fixedly connected to the bottom of the inner wall of the chute frame 1. The two ends of the first electric telescopic rod 2 are L-shaped. A lifting frame 3 is fixedly connected to the top of the first electric telescopic rod 2. Two first pulleys 4 are fixedly connected to both sides of the lifting frame 3. The two first pulleys 4 on both sides of the lifting frame 3 are slidably connected to the inner walls of both sides of the chute frame 1. A dumping plate 5 is rotatably connected to the top of the lifting frame 3. A support plate 6 is fixedly connected between the inner walls of the dumping plate 5. Two second pulleys 28 are fixedly connected to the side wall of the dumping plate 5. A toothed plate 7 is slidably connected to the side wall of the support plate 6. A striking mechanism for striking the trash can when dumping trash is provided on the side wall of the chute frame 1.

[0029] Further, see attached document. Figures 4 to 8 As shown, the striking mechanism includes a slide 8, which is fixedly connected to the top side wall of the slide frame 1. A gravity block 9 is slidably connected to the inner wall of the slide 8, and an insert block 10 is fixedly connected to the top of the gravity block 9. Slide grooves 11 are formed on both sides of the insert block 10, and sliders 12 are slidably connected inside each of the two slide grooves 11. The opposite ends of the two sliders 12 are both arc-shaped. Second springs 29 are fixedly connected to the side walls of each slider 12, and one end of the second spring 29 is fixedly connected to the inner wall of the slide groove 11. A connecting hole 13 is formed between the top of the slide frame 1 and the inner wall of one end of the slide 8. The insert block 10 passes through the connecting hole 13, which is circular in shape. A rack plate 14 is fixedly connected to the side wall of the gravity block 9, and the side wall of the slide 8 passes through... A gear 15 is rotatably connected to the mounting plate. The outer wall of the gear 15 meshes with the outer wall of the rack plate 14. A pull rope 16 is fixedly connected to the shaft of the gear 15. A support frame 17 is fixedly connected to the top of the slide frame 1. A guide wheel 26 for guiding the pull rope 16 is rotatably connected to the side wall of the support frame 17. A rubber hammer 18 is rotatably connected to the top of the support frame 17. A first spring 19 is fixedly connected to the side wall of the support frame 17 through a fixing plate. The top of the first spring 19 is fixedly connected to the bottom of the rubber hammer 18. A mounting shell 20 is fixedly connected to the side wall of the support frame 17. An elliptical block 21 for continuously lifting the rubber hammer 18 is rotatably connected to the inner wall of the mounting shell 20. A torsion spring 22 is fixedly connected between the shaft of the elliptical block 21 and the inner wall of the mounting shell 20.

[0030] When the knocking mechanism is needed to dump garbage, first place the garbage can directly in front of the toothed plate 7, aligning the groove on the side wall of the garbage can with the toothed plate 7. Then activate the second electric telescopic rod 23, which extends upward and moves the toothed plate 7 upward. After the toothed plate 7 enters the engaging groove on the side wall of the garbage can, it continues to lift the garbage can upward. During the process of lifting the garbage can, its top will contact the anti-drop plate 24, effectively clamping and engaging the garbage can to prevent it from slipping in subsequent operations.

[0031] After clamping is completed, the first electric telescopic rod 2 is activated. The first electric telescopic rod 2 extends and pushes the lifting frame 3 to move upward as a whole. Since the lifting frame 3 is provided with first pulleys 4 on both sides and the first pulleys 4 are slidably connected to the inner walls of both sides of the slide frame 1, the rise of the lifting frame 3 is more stable under the guidance of the pulleys, ensuring the stability and reliability of the movement process.

[0032] As the lifting frame 3 rises, it will drive the tilting plate 5 connected to its side wall to move upward together. When the tilting plate 5 is moved to the top of the chute frame 1 by the lifting frame 3, the second pulley 28 on the tilting plate 5 will slide in along the L-shape because the top of the chute frame 1 is an L-shaped structure. At this time, the tilting plate 5 will rotate 90° at the top of the lifting frame 3 and begin to tilt. Under the continued upward action of the first electric telescopic rod 2, the tilting angle of the tilting plate 5 will further increase, thereby making the tilting range of the garbage can greater and making it easier to dump the garbage in the can.

[0033] Meanwhile, through the linkage mechanism, when the second pulley 28 enters the L-shaped structure at the top of the slide frame 1 during the tilting process, it will contact the top of the insert block 10. Since the top of the insert block 10 has a ramp structure on both sides, it helps the second pulley 28 to smoothly press down the insert block 10. When the insert block 10 is pressed down, it will disengage from the original limiting position in the connecting hole 13. The gravity block 9 is thus released from its limiting position and begins to slide freely in the slide frame 8.

[0034] As the gravity block 9 slides down, the rack plate 14 fixedly connected to its side wall also moves, causing the gear 15 meshing with it to rotate. When the gear 15 rotates, its shaft winds the pull rope 16 and is guided by the guide wheel 26 on the support frame 17, so that the pull rope 16 drives the shaft of the elliptical block 21 in the mounting shell 20 to rotate and wind up the torsion spring 22, making it convenient for the shaft of the elliptical block 21 to rewind and rewind the pull rope 16.

[0035] The rotation of the elliptical block 21 will cause its protruding part to continuously reciprocate to lift the rubber hammer 18. During the lifting process, the first spring 19 connected to the bottom of the rubber hammer 18 is stretched. When the elliptical block 21 rotates to the concave part and no longer lifts the rubber hammer 18, the first spring 19 quickly retracts, pulling the rubber hammer 18 back, so that one end of it produces an intermittent striking action.

[0036] During the rebound process, the rubber hammer 18 will intermittently strike the top of the trash can. By utilizing the inertia and elasticity of the rubber hammer 18, the trash can is effectively vibrated, which in turn promotes the smooth falling of the trash inside the can, prevents the trash from sticking out, and improves the thoroughness and efficiency of trash disposal.

[0037] The striking mechanism, through its linkage design with the dumping process, enables automatic striking of the trash can during dumping, effectively solving the problem of trash being difficult to detach due to compaction or adhesion. The second electric telescopic rod 23 drives the toothed plate 7 to insert and lift the trash can, working in conjunction with the anti-drop plate 24 for stable clamping. The first electric telescopic rod 2 then drives the lifting frame 3 to rise, simultaneously driving the dumping plate 5 to rotate and tilt within the L-shaped structure at the top of the chute frame 1, ensuring thorough dumping. Simultaneously, the second pulley 28 presses down the insert block 10, releasing the gravity block 9. The gravity block 9 drives the rack plate 14 and gear 15 to rotate, which in turn pulls the rope 16 to make the elliptical block 21 rotate. The elliptical block 21 periodically lifts the rubber hammer 18 and stretches the first spring 19. Under the action of spring retraction, the rubber hammer 18 is intermittently struck. This design can complete the striking action through its own structure without external drive. It has a compact structure and reliable operation. It can effectively vibrate the top of the garbage can, promote the shedding of adhering garbage, improve the garbage emptying rate and automation level, and is particularly suitable for the needs of improving garbage dumping efficiency in urban street sanitation systems.

[0038] Further, see attached document. Figure 3 As shown, the support plate 6 is L-shaped. Two second electric telescopic rods 23 are fixedly connected to the bottom of the support plate 6 to drive the toothed plate 7 to move upward. An anti-fall plate 24 is fixedly connected to the top of the tilting plate 5. The second electric telescopic rods 23 and the anti-fall plate 24 can clamp garbage of different heights. At the same time, when dumping garbage from the garbage bin, the toothed plate 7 and the anti-fall plate 24 clamp the garbage bin, which improves the safety and reliability of the device during operation and avoids garbage spillage or mechanical damage caused by the garbage bin falling.

[0039] Further, see attached document. Figure 3 As shown, the top of the anti-fall plate 24 is fixedly connected to a guide plate 25 for guiding the garbage inside the trash can, thus preventing the garbage from scattering everywhere when the trash can is tilted.

[0040] Further, see attached document. Figure 5 As shown, the top two sides of the insert block 10 are provided with ramps. When the second pulley 28 is slidably connected to the top of the slide frame 1, it will contact the top of the insert block 10. When the second pulley 28 moves to the top of the slide frame 1, it will squeeze the insert block 10 and trigger the knocking mechanism to knock on the trash can. This can effectively cause the adhering or incompletely detached trash to fall out of the can, significantly improving the thoroughness of trash emptying and cleaning efficiency.

[0041] Further, see attached document. Figure 4As shown, an elastic rope 27 is fixedly connected to the top of the insertion block 10. The top end of the elastic rope 27 extends into the interior of the slide frame 1 through the connecting hole 13 and is fixedly connected to the top of the tilting plate 5. With the setting of the elastic rope 27, after the garbage can is emptied, the first electric telescopic rod 2 drives the tilting plate 5 to move downward. When it moves, it will pull the elastic rope 27, which in turn will pull the gravity block 9 to move upward. The gravity block 9 drives the insertion block 10 to re-insert into the connecting hole 13. Then, the second spring 29 squeezes the slider 12. The slider 12 extends and contacts the top of the connecting hole 13 and limits the gravity block 9 on the top of the slide frame 8, preparing for the next tap. This structure has good automatic reset performance, requires no manual intervention, and effectively improves the continuity and automation of equipment operation.
