Description

Technical Field

[0001] This utility model relates to the field of weeding device technology, specifically a weeding device with adjustable weeding width. Background Technology

[0002] The working principle of blade weed cutters is mainly based on the rotation and cutting of mechanical blades. When the machine is started, the motor or engine drives the blades to rotate at high speed, using the sharp blades to cut the weeds. This weeding method is efficient and labor-saving, and is suitable for the maintenance of large lawns or gardens. Common weed cutters generally rely on rotating blades to achieve the weeding function, but they lack the flexibility of width adjustment in their design. They do not have a width adjustment function and cannot adjust the weeding width according to the weeding situation. When the weed cutter is working in the grass, obstacles will affect the weeding work, and accidentally touching an obstacle will damage the weed cutter. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up a first electric push rod, a movable slider, and a sliding base plate, realizes that the output end of the first electric push rod drives the movable slider to slide within the adjusting support plate. The movable slider drives the sliding base plate and the inner sliding column rotating on one side to move and adjust, thereby adjusting the position of the inner sliding column within the rotating cylinder and adjusting the position of the second weeding blade, thus completing the adjustment of the weeding width to adapt to different weeding positions. By setting up a limiting post, a limiting side block, and a limiting inner groove, it is realized that when the rotating cylinder rotates, it drives the inner limiting post to rotate.

[0025] It is understood that this utility model uses a push rod 20 to move the support frame 1 and the moving wheel 2, and a controller 22 to control the second electric push rod 3. The output end of the second electric push rod 3 drives the adjusting plate 4, the fixed base plate 6, and the sliding base plate 7 to adjust their height, thereby adjusting the weeding height. When adjusting the width of the weeding area, the output end of the first electric push rod 13 drives the moving slider 14 to move, the moving slider 14 drives the sliding base plate 7 to move, and the sliding base plate 7 drives the inner sliding column 9 on the inner side to move and adjust. The sliding column 9 slides inside the rotating cylinder 8, and the second weeding blade 11 enters the movable groove 12 to adjust the width of weeding. The inner sliding column 9 slides outside the limiting column 17, and the limiting inner groove 19 and the limiting side block 18 on the inner side of the inner sliding column 9 limit each other. During weeding, the output end of the motor 16 drives the rotating cylinder 8 to rotate. When the rotating cylinder 8 rotates, the limiting inner groove 19 and the inner sliding column 9 rotate synchronously through the limiting column 17 and the limiting side block 18. The weeding work is completed by the first weeding blade 10 outside the rotating cylinder 8 and the second weeding blade 11 outside the inner sliding column 9.

A limit slide rod 5 is symmetrically fixed to the top of the adjusting support plate 4. The limit slide rod 5 is slidably connected to the support frame 1.

[0033] It is understood that the output end of the motor 16 of this utility model drives the rotating cylinder 8 to rotate. When the rotating cylinder 8 rotates, it drives the inner sliding column 9 on the inner side to rotate synchronously, and the weeding work is completed by the first weeding blade 10 and the second weeding blade 11.

[0034] Please see Figures 1 to 4 A battery 21 is installed on the top of the support frame 1, a controller 22 is installed on the top of the support frame 1, and a push rod 20 is fixedly connected to the top of the support frame 1.
