[0021] To achieve this objective, the present invention adopts the following technical solution:
[0022] The unmanned sweeper includes a vehicle body and the aforementioned automatic dumping garbage bin device, with the bracket mounted on the vehicle body.
[0023] The beneficial effects of this utility model are:
[0024] The automatic garbage bin disposal device provided by this utility model includes a support frame, a garbage bin, a lifting assembly, and a dumping assembly. The lifting assembly includes two first driving members and two lifting arms, which are located on opposite sides of the garbage bin. Each lifting arm's two ends are rotatably connected to a first position on the support frame and a second position on the garbage bin. The output ends of the two first driving members are connected to the corresponding lifting arms. The first driving members can drive the lifting arms to rotate, thereby lifting the garbage bin directly above the docking garbage truck or standard garbage bin, facilitating subsequent dumping of garbage into the docking garbage truck or standard garbage bin. Lifting arms are provided on both sides of the garbage bin to improve stability during the lifting process. The dumping assembly includes a second driving member and a tilting arm. The two ends of the tilting arm are rotatably connected to a third position on the support frame and a fourth position on the garbage bin. The output end of the second driving member is connected to the tilting arm, which drives the tilting arm to rotate the garbage bin, aligning the opening of the garbage bin with the docking garbage truck or standard garbage bin for dumping, thus achieving automatic garbage dumping and saving labor costs. The first and third positions are spaced apart on the support, while the second and fourth positions are spaced apart on the same side of the garbage hopper. This, along with the spacing between the first and second positions, the spacing between the second and fourth positions, the lifting arm, and the tilting arm, forms a four-bar structure with fewer components and a simpler structure. Furthermore, the garbage hopper has two support points on one side (the second and fourth positions), which improves its stability, prevents garbage spillage, and distributes the stress between the lifting and tilting arms, extending their service life and thus extending the lifespan of the automatic garbage dumping device. During the process of lifting the garbage hopper from the receiving position to the tilting position, the tilting arm keeps the hopper vertical. When the garbage hopper is dumped, the lifting arm supports the hopper, and the tilting arm pushes the hopper to rotate around the fourth position. Therefore, the lifting and tilting arms work together to make the lifting and tilting process of the garbage hopper smoother and prevent garbage spillage. Attached Figure Description

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0035] This embodiment provides an automatic dumping garbage bin device, which can automatically dump garbage, saving labor costs; the garbage bin moves smoothly during the dumping process, avoiding garbage spillage; and it has a long service life.
[0036] Specifically, such as Figures 1 to 4 As shown, the automatic dumping garbage bin device includes a bracket 100, a garbage bin 200, a lifting assembly, and a dumping assembly. The bracket 100 can be fixed to the body of the unmanned sweeper, and the garbage bin 200 is used to hold the swept garbage. The lifting assembly includes two first drive members 310 and two lifting arms 320. The two lifting arms 320 are located on opposite sides of the garbage bin 200. In this embodiment, the two lifting arms 320 are located on both sides along the width direction (left-right direction) of the vehicle body, so that the garbage bin 200 can be lifted from the rear side of the vehicle body. The two ends of each lifting arm 320 are rotatably connected to a first position of the bracket 100 and a second position of the outer side wall of the garbage bin 200, respectively. Both first drive members 310 are fixed to the bracket 100, and the output ends of the two first drive members 310 are respectively connected to the corresponding lifting arms 320. The dumping assembly includes a second drive member 410 and a tilting arm 420. The two ends of the tilting arm 420 are rotatably connected to a third position on the support 100 and a fourth position on the outer wall of the garbage hopper 200, respectively. The second drive member 410 is fixed to the support 100, and its output end is connected to the tilting arm 420. The first and third positions are spaced apart on the support 100, and the corresponding second and fourth positions are spaced apart on the same outer wall of the garbage hopper 200. During the process of lifting the garbage hopper 200 from the receiving position to the dumping position, the first drive member 310 drives the lifting arm 320 to lift the garbage hopper 200. The tilting arm 420 and the weight of the garbage hopper 200 themselves keep the garbage hopper 200 vertical. When the garbage hopper 200 dumps garbage, the lifting arm 320 supports the garbage hopper 200, and the second drive member 410 drives the tilting arm 420 to rotate the garbage hopper 200.
[0037] It should be noted that the garbage hopper 200 is always vertically positioned, i.e., with its opening facing upwards, both in the garbage-loading position and when it is lifted to the dumping position. In this embodiment, the lifting arm 320 is approximately L-shaped. The relatively short side of the L-shaped lifting arm 320 is connected to the garbage hopper 200, and the relatively long side is connected to the support 100, so that the garbage hopper 200 can be stored at the bottom of the frame when in the garbage-loading position. The output end of the first driving member 310 is connected to the middle of the relatively long side of the L-shaped lifting arm 320, and is slightly inclined away from the support 100 relative to the vertical direction, i.e., there is a certain angle between the first driving member 310 and the vertical direction, which facilitates pushing the lifting arm 320.
[0038] Based on the above design, the lifting assembly includes two first drive members 310 and two lifting arms 320. The two lifting arms 320 are located on opposite sides of the garbage bin 200, and the two ends of each lifting arm 320 are rotatably connected to the first position of the bracket 100 and the second position of the garbage bin 200, respectively. The output ends of the two first drive members 310 are respectively connected to the lifting arms 320 on the corresponding side. The first drive members 310 can drive the lifting arms 320 to rotate, thereby lifting the garbage bin 200 directly above the docking garbage truck or standard garbage bin, so as to facilitate the subsequent dumping of garbage into the docking garbage truck or standard garbage bin. Furthermore, lifting arms 320 are provided on both sides of the garbage bin 200 to improve the stability of the garbage bin 200 during the lifting process. The dumping assembly includes a second drive unit 410 and a tilting arm 420. The two ends of the tilting arm 420 are rotatably connected to the third position of the bracket 100 and the fourth position of the garbage bin 200, respectively. The output end of the second drive unit 410 is connected to the tilting arm 420, which can drive the tilting arm 420 to push the garbage bin 200 to rotate, so that the opening of the garbage bin 200 is aligned with the docking garbage truck or standard garbage bin to dump garbage, thereby realizing automatic garbage dumping and saving labor costs. The intervals between the first and second positions, the intervals between the second and fourth positions, the lifting arm 320, and the tilting arm 420 form a four-bar structure, which has fewer parts and a simpler structure. Furthermore, compared to the situation where the lifting arm 320 and the tilting arm 420 are both connected to the garbage bin 200 at the same position, the garbage bin 200 has two support points on one side, the second and fourth positions. This not only improves the stability of the garbage bin 200 and prevents garbage from spilling, but also allows the lifting arm 320 and the tilting arm 420 to share the stress, extending the service life of the lifting arm 320 and the tilting arm 420, thereby extending the service life of the automatic garbage bin tilting device. During the process of lifting the garbage hopper 200 from the loading position to the dumping position, the tilting arm 420 can keep the garbage hopper 200 vertical. When the garbage hopper 200 dumps garbage, the lifting arm 320 supports the garbage hopper 200, and the tilting arm 420 pushes the garbage hopper 200 to rotate around the fourth position. Therefore, the lifting arm 320 and the tilting arm 420 can work together to make the lifting and dumping process of the garbage hopper 200 more stable and prevent garbage from spilling.
[0039] In this embodiment, both the first driving component 310 and the second driving component 410 are hydraulic cylinders.
[0040] Optionally, the automatic dumping garbage bin device includes two second driving members 410 and two tilting arms 420, with each second driving member 410 and tilting arm 420 corresponding to the other. One end of each tilting arm 420 is connected to two fourth positions on opposite sides of the garbage bin 200. Compared to setting a tilting arm 420 on only one side of the garbage bin 200, setting two second driving members 410 and tilting arms 420 can simultaneously drive both sides of the garbage bin 200 to rotate, making the garbage bin 200 more evenly stressed, thereby improving the stability of the garbage bin 200 during lifting and dumping, and extending the service life of the lifting and dumping components.
[0041] Optionally, continue as follows Figure 2 and Figure 3 As shown, the lifting assembly also includes a first pin 330, one end of which is fixed to the second position of the garbage hopper 200, and the other end of which is rotatably connected to the lifting arm 320. The tilting assembly also includes a second pin 430, one end of which is fixed to the fourth position of the garbage hopper 200, and the other end of which is rotatably connected to the tilting arm 420. The first pin 330 enables the rotatable connection between the lifting arm 320 and the support 100, and the second pin 430 enables the rotatable connection between the tilting arm 420 and the support 100. The connection is simple and has high strength.
[0042] Furthermore, the automatic dumping garbage bin device also includes a fixing plate 500, which is attached to the outer wall of the garbage bin 200. The first pin 330 and the second pin 430 are sequentially connected to the garbage bin 200, the fixing plate 500, and the lifting arm 320. The fixing plate 500 simultaneously strengthens the connection between the first pin 330, the second pin 430, and the garbage bin 200, and also functions as a gasket.
[0043] Optionally, the bracket 100 is provided with ear plates 110, with the first position and the fourth position spaced apart on the ear plates 110. The ear plates 110 are used to connect the lifting arm 320 and the tilting arm 420 to the bracket 100, which facilitates the assembly of the four-bar structure.
[0044] To increase the structural strength of the automatic dumping garbage bin device, specifically, a first reinforcing plate 340 is attached to the outer side of the lifting arm 320; and a second reinforcing plate 440 is attached to the outer side of the tilting arm 420.
[0045] In this embodiment, the shape of the first reinforcing plate 340 is adapted to the shape of the lifting arm 320, and the shape of the second reinforcing plate 440 is adapted to the shape of the tilting arm 420.
[0046] To further increase the structural strength of the lifting arm 320 and the operational stability of the garbage bin 200, the lifting assembly also includes a reinforcing beam 360, which is located between the two lifting arms 320 and connected to the two lifting arms 320 at both ends.
[0047] In order to enable the two lifting arms 320 to lift the garbage bin 200 synchronously, the lifting assembly also includes a connecting rod 350. The two ends of the connecting rod 350 are respectively connected to the two lifting arms 320 and respectively connected to the first driving member 310 on the corresponding side. That is, the output end of the first driving member 310 is connected to the lifting arm 320 through the connecting rod 350.
[0048] Furthermore, the automatic dumping garbage bin device also includes two locking components 351, which are used to fix the connecting rod 350 and the corresponding lifting arm 320 respectively, thereby increasing the connection strength between the connecting rod 350 and the lifting arm 320.
[0049] This embodiment also provides an unmanned sweeper, which can automatically dump garbage, saving labor costs; the garbage bin moves smoothly during the dumping process, avoiding garbage spillage; and it has a long service life.
[0050] Specifically, the unmanned sweeper includes a vehicle body and the aforementioned automatic dumping garbage bin device. A support frame 100 is mounted on the vehicle body. The lifting assembly includes two first drive members 310 and two lifting arms 320. The two lifting arms 320 are located on opposite sides of the garbage bin 200, and both ends of each lifting arm 320 are rotatably connected to a first position of the support frame 100 and a second position of the garbage bin 200, respectively. The output ends of the two first drive members 310 are respectively connected to the corresponding lifting arms 320. The first drive members 310 can drive the lifting arms 320 to lift the garbage bin 200, placing the garbage bin 200 in a position... The garbage bin 200 is positioned directly above the garbage truck or standard garbage bin, with lifting arms 320 on both sides to improve its stability during lifting. The dumping assembly includes a second drive unit 410 and a tilting arm 420. The two ends of the tilting arm 420 are rotatably connected to the third position of the bracket 100 and the fourth position of the garbage bin 200, respectively. The output end of the second drive unit 410 is connected to the tilting arm 420, which can drive the tilting arm 420 to push the garbage bin 200 to rotate, so that the opening of the garbage bin 200 is aligned with the garbage truck or standard garbage bin for dumping garbage, thereby achieving automatic garbage dumping and saving labor costs. The first and third positions are spaced apart on the support 100, and the second and fourth positions are spaced apart on the same side of the garbage bin 200. Thus, the spacing between the first and second positions, the spacing between the second and fourth positions, the lifting arm 320, and the tilting arm 420 can form a four-bar structure with fewer parts and a simpler structure. Furthermore, the garbage bin 200 has two support points on one side, the second and fourth positions, which can not only improve the stability of the garbage bin 200 and prevent garbage from spilling, but also allow the lifting arm 320 and the tilting arm 420 to share the stress, extending the service life of the lifting arm 320 and the tilting arm 420, thereby extending the service life of the automatic garbage bin device. During the process of lifting the garbage hopper 200 from the loading position to the dumping position, the tilting arm 420 can keep the garbage hopper 200 vertical. When the garbage hopper 200 dumps garbage, the lifting arm 320 supports the garbage hopper 200, and the tilting arm 420 pushes the garbage hopper 200 to rotate around the fourth position. Therefore, the lifting arm 320 and the tilting arm 420 can work together to make the lifting and dumping process of the garbage hopper 200 more stable and prevent garbage from spilling.
