A control box 2 is fixedly connected to the bottom of the frame 1, and a first support sleeve 7 and two second support sleeves 8 are rotatably connected in the control box 2, and the two second support sleeves 8 are respectively located on both sides of the first support sleeve 7; A translation mechanism for driving the two second support sleeves 8 to move in different directions is installed in the control box 2. When the frame 1 moves, the two second support sleeves 8 are driven to move in different directions by the translation mechanism, and the spacing between the two second support sleeves 8 is increased, so that the second support sleeves 8 drive the auxiliary mowing structure to bypass the seedlings in each row, thereby preventing the auxiliary mowing structure from cutting the seedlings. The control box 2 is installed with a driver adapted to the first support sleeve 7, and the first support sleeve 7 is driven to rotate by the driver; The outer rotating sleeve of the second support sleeve 8 is provided with a swing seat 10, and a support shaft 11 is rotatably connected to the swing seat 10. A synchronous rotation component is installed on the first support sleeve 7, the second support sleeve 8 and the support shaft 11. The synchronous rotation component is used to drive the first support sleeve 7, the second support sleeve 8 and the support shaft 11 to rotate synchronously. The first support sleeve 7 is installed with a main mowing structure, and the second support sleeve 8 is installed with an auxiliary mowing structure. The initial position of the main mowing structure is located between two adjacent rows of seedlings, and the initial position of the auxiliary mowing structure is located between two adjacent seedlings in a row. The first support sleeve 7 is driven to rotate by a driver, and the first support sleeve 7 drives the support shaft 11 and the second support sleeve 8 to rotate synchronously through the synchronous rotation component, and The first support sleeve 7 drives the main mowing structure to rotate, and the second support sleeve 8 drives the auxiliary mowing structure to rotate. The rotating main mowing structure is used to cut the weeds between two adjacent rows of seedlings. As the frame 1 moves, the two second support sleeves 8 are driven to move in different directions through the translation mechanism, so that the second support sleeves 8 drive the auxiliary mowing structure to bypass the seedlings in each row, and the weeds between two adjacent seedlings in each row are cut by the rotating auxiliary mowing structure. During the walking of the frame 1 through the wheel-type walking mechanism, the weeds between two adjacent rows of seedlings in the horizontal direction can be cut, and the weeds between two adjacent seedlings in the vertical direction can also be cut.

The tension spring 28 is in a tensioned state in an initial state. The tension spring 28 applies tension to the slider 27 and the pull rope 24. When the swing seat 10 moves horizontally, the swing seat 10 pulls the slider 27 to move through the pull rope 24, and the tension spring 28 applies tension to the slider 27, so that the third damping disc 14 is always aligned with the first damping disc 12. The third gear plate 42 is in contact with or always meshed with the first gear plate 40 to ensure the stability of the transmission. Two guide wheels 23 compatible with the pull rope 24 are rotatably connected in the control box 2, and the pull rope 24 is guided by the guide wheel 23, so that the pull rope 24 moves in the pulling direction of the slider 27 and the opening direction of the slide groove 26, so that the slider 27 can slide smoothly relative to the slide groove 26, reducing the friction between the slider 27 and the slide groove 26, and increasing the stability of the swing seat 10 when rotating relative to the second support sleeve 8, thereby ensuring that the first support sleeve 7 drives the second support sleeve 8 to rotate synchronously, and the second support sleeve 8 can cut weeds through the auxiliary mowing structure.
