DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Please refer to Figure 1-10 ;

[0034] The utility model discloses an automatic feeding device for a garbage bin, referring to Figure 1-3 , including a compression bin 1, a cover plate 2 is rotatably connected to one side of the upper end of the compression bin 1, and the cover plate 2 and the compression bin 1 are rotated so that an opening is opened between the cover plate 2 and the compression bin 1 for the garbage can to pour garbage into the compression bin 1; at the same time, the cover plate 2 is rotated to close the opening between the cover plate 2 and the compression bin 1, which can, on the one hand, enable the push-pull assembly arranged in the compression bin 1 to compress the garbage; on the other hand, it can seal the garbage to cover up the garbage smell and protect the surrounding environment;

[0035] The compression bin 1 includes a first driving device, which is used to drive the cover plate 2 to rotate; a bucket rack 3 is arranged on the outside of the compression bin 1, and the upper end of the bucket rack 3 is arranged with lifting teeth 4, which can hang the trash can, so that the bucket rack 3 can drive the trash can to move when it moves. The bucket rack 3 is movably connected to the cover body through a connecting rod assembly, and the movement of the cover body can drive the bucket rack 3 to move through the connecting rod assembly, thereby driving the trash can to move.

[0036] Two guide rails 5 are also provided on the outside of the compression bin 1. The two guide rails 5 are distributed on both sides of the bucket rack 3. In this embodiment, the opening directions of the two guide rails 5 are both toward the bucket rack 3. A space is formed between the cover plate 2 and the compression bin 1 to place the curved part of the guide rail 5. A fixing block 6 is fixedly provided on the straight rail of the guide rail 5. The other end of the fixing block 6 is fixedly connected to the compression bin 1, so as to fix the guide rail 5 on the compression bin 1. It is worth noting that the distance between the two guide rails 5 is not limited, and the two guide rails 5 can adapt to trash cans of a certain length range.

[0037] The trajectory of the guide rail 5 corresponds to the dumping path of the trash can. The curved part of the guide rail 5 is in the shape of an inverted hook. The curved part of the guide rail 5 can be hung on the compression bin 1. On the one hand, the curved part of the guide rail 5 is hung on the compression bin 1, which further fixes the guide rail 5. On the other hand, the distance between the straight rail part of the guide rail 5 and the compression bin 1 is reduced, thereby improving the space utilization performance of the device. The bucket rack 3 is provided with two groups of pulleys 7, and the bucket rack 3 is movably connected with the pulley 7. The two groups of pulleys 7 are respectively slidably connected with the two guide rails 5. The bucket rack 3 can slide relative to the guide rail 5 through the pulley 7. It is worth noting that in this embodiment, there is no limitation on the number of a group of pulleys, so as to meet the sliding of the pulley 7 on the straight rail part and the curved part of the guide rail 5. The pulley 7 slides on the guide rail 5, and the guide rail 5 can limit the sliding direction of the pulley 7, thereby limiting the movement direction of the trash can.

[0038] In order to further facilitate the use of the operator, the bucket rack 3 is provided with a first alignment portion 8 and a second alignment portion 9, the first alignment portion 8 is fixedly connected to the bucket rack 3; the second alignment portion 9 is fixedly connected to the bucket rack 3, and an anti-collision position (not marked in the figure) is provided on the side of the compression bin 1 facing the bucket rack 3, and the anti-collision position is used to prevent the hook arm truck from colliding with the garbage bin when pulling the garbage bin.

[0039] Specifically, refer to Figure 1 and Fig. 9 When the operator needs to pour the garbage in the garbage bin into the compression bin 1, he first pushes the garbage bin to the position of the bucket lifting rack 3. When the garbage bin abuts against the first alignment portion 8 and the second alignment portion 9, the handle of the garbage bin is aligned with the lifting teeth 4 of the bucket lifting rack 3 in the vertical direction. At this time, the first driving device drives the cover plate 2 and the compression bin 1 to open the opening, so that the garbage in the garbage bin can be dumped into the compression bin 1. At the same time, the cover plate 2 and the compression bin 1 rotate, and the cover plate 2 drives the bucket lifting rack 3 to rise through the connecting rod assembly. The lifting rack 3 rises, that is, the lifting teeth 4 located on the bucket lifting rack 3 will also be driven to rise. During the rising process, the lifting teeth 4 will hang on the handle of the garbage bin, thereby driving the garbage bin to rise; the pulley 7 slides in the guide rail 5. In this embodiment, since the guide rail 5 has a curved portion, a group of pulleys 7 including a first pulley 7 and a second pulley 7 are used. The first pulley 7 and the second pulley 7 slide on the slide rail in the following stages:

[0040] The first stage: the first pulley 7 and the second pulley 7 both slide upward on the straight rail portion of the guide rail 5. At this time, the bucket rack 3 moves vertically upward, and the trash can is driven to move upward;

[0041] In the second stage, the first pulley 7 guides the curved part of the guide rail 5, and the second pulley 7 still moves on the straight part of the guide rail 5. At this time, the bucket rack 3 begins to bend upward, and the bending direction is toward the opening direction of the compression bin 1 and the cover plate 2. The trash can is also driven to bend toward the opening direction of the compression bin 1 and the cover plate 2.

[0042] In the third stage, the first pulley 7 slides to the end of the curved portion of the guide rail 5, and the second pulley 7 also slides on the curved portion of the guide rail 5. The bucket rack 3 drives the trash can to the best position for dumping the trash, and all the trash in the trash can is dumped into the compression bin 1. At the same time, the opening between the cover plate 2 and the compression bin 1 reaches its maximum.

[0043] After the first pulley 7 reaches the end of the curved portion of the guide rail 5 and stays there for a period of time sufficient to allow the garbage to be dumped out of the trash can, the first driving device will drive the cover plate 2 to begin to rotate in the opposite direction to close the opening between the cover plate 2 and the compression chamber 1. At the same time, under the action of the connecting rod assembly, the pulley 7 moves on the guide rail 5 in a direction opposite to its previous moving direction, so that the garbage can that has been dumped begins to descend. When the garbage can falls to its original position, the bucket lifting rack 3 will still fall a distance to allow the lifting teeth 4 on the bucket lifting rack 3 to disengage from the handle of the garbage can.

[0044] In the present embodiment, in order to achieve the effect of improving the operator's control device, the compression chamber 1 is also provided with a control panel 10. Specifically, in the present embodiment, the driving energy source of the first driving device is not limited, and it can be electric energy, air pressure or hydraulic pressure, etc. In the present embodiment, taking the first driving device including a hydraulic cylinder 11 as an example, the cylinder end of the hydraulic cylinder 11 is rotatably connected to the compression chamber 1, and the direction of rotation is consistent with the rotation direction of the cover plate 2; a connecting block 12 is provided in the middle position of the cover plate 2, and the shape of the connecting block 12 is not limited. In the present embodiment, taking the shape of the connecting block 12 as a triangular prism as an example, one side of the connecting block 12 is adapted to the shape of the cover plate 2, and the side is fixedly connected to the cover plate 2, and the connecting block 12 is provided with a through hole 13, and the end of the piston shaft of the hydraulic cylinder 11 away from the hydraulic cylinder 11 is a cylindrical cylinder, and the hole wall of the through hole 13 is provided with a linkage shaft, which passes through the through hole 13 and the cylindrical portion of the piston shaft of the hydraulic cylinder 11, and the linkage shaft is rotatably connected to the through hole 13 and the cylindrical portion of the piston shaft of the hydraulic cylinder 11.

[0045] When in use, the compression cylinder (not shown in the figure) is connected to the hydraulic cylinder 11, and the operator needs to pour the garbage in the trash can into the compression chamber 1 first. When implementing this operation, the operator needs to push the trash can to the position of the bucket lifting rack 3 first, until the trash can abuts against the first alignment part 8 and the second alignment part 9, and the operator then presses the button for raising the bucket lifting rack 3 on the control panel 10, and the piston shaft of the hydraulic cylinder 11 will extend to drive the cover plate 2 and the compression chamber 1 to rotate. After the cover plate 2 and the compression chamber 1 rotate to the maximum position of the opening, the compression cylinder stroke is completed and the bucket lifting rack 3 stops moving, thereby completing the garbage dumping; after dumping, the operator presses the button for lowering the bucket lifting rack 3, and the control panel 10 will control the contraction of the piston shaft of the hydraulic cylinder 11 to drive the cover plate 2 to rotate in the opposite direction to close the opening between the cover plate 2 and the compression chamber 1.

[0046] In this embodiment, the connecting rod assembly is not limited. In order to make the embodiment clearer, this embodiment explains the connecting rod assembly in one manner:

[0047] Specifically, the connecting rod assembly includes two connecting rods 14, and the bucket rack 3 is fixedly provided with two rod receiving grooves 15, the two rod receiving grooves 15 are located on both sides of the bucket rack 3, and the two connecting rods 14 are respectively placed in the two rod receiving grooves 15, and the connecting rod 14 includes a connecting rod body 141 and a ball head hanging ring 142, and the two ends of the connecting rod body 141 are threaded rods 143 with external threads, and one end of the ball head hanging ring 142 is provided with a threaded tube 1421, and the threaded rod 143 is threadedly connected with the threaded tube 1421; one end of the two connecting rods 14 is respectively hinged to the two ends of the cover plate 2 on the side facing the bucket rack 3, and the hinge joint is described below by taking one place as an example. The structure is described as follows: the hinge between the cover plate 2 and the connecting rod 14 includes two protruding pieces 16, and a rotating shaft is rotatably arranged between the two protruding pieces 16. The length direction of the rotating shaft is perpendicular to the length direction of the connecting rod 14, and the rotating shaft passes through the ball head hanging ring 142, so that the connecting rod 14 is rotatably connected to the rotating shaft; the other ends of the two connecting rods 14 are respectively hinged to the bucket rack 3 through a hinge assembly, and the hinge assembly is described below by taking one place as an example: the hinge assembly includes a hinge shaft, which is rotatably installed between the inner groove walls on both sides of the rod containing groove 15, and the ball head hanging ring 142 of the connecting rod 14 is rotatably connected to the hinge shaft.

[0048] When in use, the operator starts the hydraulic cylinder 11 through the control panel 10, and the hydraulic cylinder 11 can drive the cover plate 2 to rotate.

[0049] Thereby, one end of the connecting rod 14 arranged at the end of the cover plate 2 is driven to rotate along the rotating axis. The connecting rod 14 rotates freely on the rotating axis through the ball head hanging ring 142, and the other end drives the bucket lifting frame 3 to move through the hinge assembly. The bucket lifting frame 3 slides along the guide rail 5 under the action of the connecting rod 14, so that the garbage can is lifted to the predetermined position. After the bucket lifting frame 3 is lifted to the predetermined position, the garbage is dumped through the dumping path. After the garbage is dumped, the piston shaft of the hydraulic cylinder 11 contracts, the cover plate 2 begins to close, and the connecting rod 14 drives the bucket lifting frame 3 to reset in the reverse direction.

[0050] In order to further improve the stability of the movement of the bucket rack 3, a roller track 17 is further provided on the side of the compression bin 1 close to the bucket rack 3, and a roller rack 18 is provided on the bucket rack 3. A roller 19 is provided on the roller rack 18, and the roller 19 can roll along the roller track 17. The shape of the roller track 17 corresponds to the guide rail 5. In the straight rail part of the guide rail 5, the roller track 17 is also a straight rail part; in the curved part of the guide rail 5, the roller track 17 is a convex part, and at the same time, the convex part of the roller track 17 forms an inverted hook shape, and the convex part of the roller track 17 is upside down on the compression bin 1; in order to further achieve the stability of the trash can when dumping garbage, a stabilizing bucket rack is also provided on the roller rack 18 in this embodiment, and the two ends of the stabilizing bucket rack 20 are respectively fixedly connected to the two roller racks 18, and the stabilizing bucket rack 20 is used to prevent the trash can from falling into the compression bin 1 when it moves to a certain angle.
