[0017] 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.

[0018] See also Figure 1 and Figure 2This utility model provides a technical solution: a garbage bin lifting mechanism for a sweeper, including a frame 1. A roller cover 3 and a lifting device fixing frame 4 are fixed inside the frame 1. Connecting ears are formed on both sides of the roller cover 3, which is connected to the frame 1 using fasteners. The lifting device fixing frame 4 is welded inside the frame 1 and is located below the roller cover 3. A lifting device 5 is fixed on the top wall of the lifting device fixing frame 4. The lifting device 5 is an electric push rod or a hydraulic cylinder. A lifting frame 6 is connected to the lower output end of the lifting device 5. The lifting frame 6 is located at the rear of the frame 1 and is used to hold the garbage bin. When the output end of the lifting device 5 retracts, the lifting frame 6 rises, clamping the garbage bin between the roller cover 3 and the lifting frame 6, thus fixing the garbage bin. When the garbage bin needs to be lowered, the output end of the lifting device 5 extends downwards, causing the lifting frame 6 to move downwards. When the lifting frame 6 is close to the ground, the garbage bin can be pulled out from between the lifting frame 6 and the roller cover 3, making it convenient to use and replace the garbage bin and reducing workload.

[0019] A tire 2 is rotatably connected to the outer side of the frame 1. When the lifting frame 6 descends, it lifts the frame 1 and the tire 2, making it easier to replace the tire 2 and improving tire changing efficiency.

[0020] The lifting device fixing frame 4 is U-shaped, and guide grooves 41 are provided on both side walls of the lifting device fixing frame 4. The lifting frame 6 has an L-shaped cross-section and includes a side frame 64 and a base frame 63. The side frame 64 is inverted U-shaped and located inside the lifting device fixing frame 4. Guide wheels 61 are rotatably connected to the two outer walls of the side frame 64. There are two guide wheels 61 on each side, symmetrically distributed on the side walls of the side frame 64. The guide wheels 61 roll in the guide grooves 41. Through the cooperation between the guide wheels 61 and the guide grooves 41, the side frame 64 moves smoothly in the lifting device fixing frame 4, and at the same time guides the up and down movement of the lifting frame 6.

[0021] A pad 7 is fixed on the base frame 63. The trash can is placed on the pad 7. The pad 7 increases the contact area with the trash can, so that the trash can can be placed stably.

[0022] A reinforcing rib 62 is fixed on one side of the lifting frame 6, and a reinforcing rib 62 is also fixed on the lower side of the lifting device fixing frame 4. The two reinforcing ribs 62 are distributed in front and behind. By setting the reinforcing ribs 62, the rigidity of the lifting device fixing frame 4 and the rigidity of the lifting frame 6 are enhanced, and the stability of the device operation is improved.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
