[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0022] like Figures 1 to 5 In the embodiment of the garden greening weeding device of the present invention shown, the garden greening weeding device includes a movable base 1 and a housing 2. The housing 2 is fixedly connected to the upper part of the movable base 1. The front part of the movable base 1 is provided with a sliding telescopic rotating blade 3. The bottom center of the rotating blade 3 is threadedly connected to a telescopic screw 4. The bottom end of the telescopic screw 4 is fixedly connected to an adapting wheel 5. The middle part of the movable base 1 is provided with a collection port 6. Multiple weed-shoveling teeth 7 are fixedly connected to the collection port 6. A rotatable roller 8 is rotatably connected to the housing 2. A fork 9 that crosses and adapts to the weed-shoveling teeth 7 is fixedly connected to the roller 8. A grass storage box 10 is provided behind the collection port 6 of the housing 2.

[0023] Specifically, the telescopic screw 4 is adjusted so that the distance between the adapting wheel 5 and the rotating cutter head 3 matches the cutting height. When the moving base 1 moves forward, the adapting wheel 5 always contacts the grass. When the adapting wheel 5 extends and retracts with the terrain, it drives the rotating cutter head 3 to move up and down to adapt to the undulations of the micro-terrain. The cut grass is scooped up by the grass-shoveling teeth 7 when the moving base 1 moves, and then pushed into the grass storage box 10 by the rotating roller 8.

[0024] In one embodiment of this application, preferably, a motor base 11 is fixedly connected to the movable base 1, and a weeding motor 12 that can slide up and down elastically is provided in the motor base 11. The drive shaft of the weeding motor 12 is fixedly connected to the rotating cutter head 3, so as to make the weeding motor 12 move up and down linearly in the motor base 11.

[0025] In one embodiment of this application, preferably, the motor base 11 is provided with a sliding groove 13, and a slider 14 is slidably connected in the sliding groove 13. The slider 14 is fixedly connected to the weeding motor 12. A telescopic tube 15 is fixedly connected to the top of the motor base 11. A push column 16 is provided in the telescopic tube 15. The bottom end of the push column 16 is fixedly connected to the top end of the weeding motor 12. A spring 17 is fixedly connected to the top end of the push column 16. The other end of the spring 17 abuts against the top end of the telescopic tube 15, so that the weeding motor 12 can only move up and down in a straight line when it rotates. The spring 17 pushes the weeding motor 12 to indirectly push the adapting wheel 5 to always abut against the grass, so that the weeding motor 12 moves up and down with the terrain.

[0026] In one embodiment of this application, preferably, the motor base 11 is provided with heat dissipation holes 18 to prevent the weeding motor 12 from overheating in the motor base 11.

[0027] In one embodiment of this application, preferably, a crushing roller 19 is rotatably connected to the housing 2 above the collection port 6 to crush the collected grass and reduce the volume of the crushed grass.

[0028] In one embodiment of this application, preferably, a blower 20 is installed on the top of the hay storage box 10 to suck the crushed hay into the hay storage box 10, so as to prevent the crushed hay from falling onto the grass from the collection port 6.

[0029] In one embodiment of this application, preferably, a dual-axis motor 21 is fixedly connected inside the housing 2. A large drive wheel 22 and a small drive wheel 23 are fixedly connected to the drive shaft of the dual-axis motor 21. A large pulley 24 is fixedly connected to the outside of the housing 2 for the rotary roller 8. A small pulley 25 is fixedly connected to the outside of the housing 2 for the crushing roller 19. The large pulley 24 is belt-connected to the small drive wheel 23, and the small pulley 25 is belt-connected to the large drive wheel 22. This is used to drive the rotary roller 8 and the crushing roller 19 to rotate. To adapt to the low rotation speed of the rotary roller 8 and the high rotation speed of the crushing roller 19, the large and small drive wheels and the large and small pulleys are used for acceleration and deceleration.

[0030] In one embodiment of this application, preferably, the movable base 1 is rotatably connected with a movable wheel 26, the rear of the hay storage box 10 is provided with a discharge door 27, and the machine casing 2 is fixedly connected with a handrail 28 to assist the movement of the movable base 1. The discharge door 27 facilitates the unloading of hay from the hay storage box 10, and the handrail 28 facilitates the push and use by the worker.

[0031] In summary, the landscaping weeding device in the above embodiments of this utility model specifically adjusts the distance between the adapting wheel 5 and the rotating blade 3 according to the required height of the grass cutting. When the handle 28 is pushed forward, the adapting wheel 5 always contacts the grass. When the adapting wheel 5 extends and retracts with the terrain, it drives the rotating blade 3 to move up and down to adapt to the undulations of the micro-terrain. The cut grass is scooped up by the grass-shoveling teeth 7 when the moving base 1 moves. After being scooped up, it is pushed into the collection port 6 by the rotating roller 8. After the weeds are crushed at the collection port 6, they are sucked into the grass storage box 10 under the action of the blower 20. This device uses the elastic sliding weeding motor 12 to drive the rotating blade 3 to change the cutting height according to the terrain when the adapting wheel 5 moves with the terrain.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
