All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes: The frame 1 is equipped with several rollers 2, and a limit plate 3 is fixed on the rear side wall of the frame 1. The positioning rod 4 is fixed on the crossbar of the frame 1. The frame 1 is moved on the soil by the cooperation of the tie rod and the rollers 2. Two rotating plates 5 are provided, each with a slot 6 at its front bottom. The bottom of the frame 1 is screwed onto the inner wall of the slot 6 using a rotating rod. The top front of the rotating plate 5 is fixed to the positioning rod 4 with bolts. A limiting groove 7 is provided on the rear side of the rotating plate 5. The limiting plate 3 is engaged with the limiting groove 7. The rotating plate 5 blocks the leaves of the broccoli seedlings from being damaged. A soil retaining plate 19 is symmetrically fixed on the crossbar at the bottom of the frame 1. The top of the soil retaining plate 19 is provided with a soil return plate 20 to block the soil between the two rotating plates 5 and prevent soil splashing. Limiting blocks 21 are fixed at both ends of the limiting plate 3. The limiting blocks 21 are engaged with the rotating plate 5 to restrict the movement of the rotating plate 5. A limiting ball 22 is fixed on the inner wall of the limiting groove 7. The limiting ball 22 is engaged with the limiting plate 3 to prevent wear between the inner wall of the limiting groove 7 and the limiting plate 3 and extend the service life of the limiting plate 3. The movable frame 8 is set between two rotating plates 5 by means of an adjusting component 9, and the adjusting component 9 is connected to the rotating plates 5. The adjusting component 9 controls the movement of the movable frame 8 and controls the tilt angle of the rotating plates 5 at the same time. The weeding roller 10 is screwed onto the vertical rod of the movable frame 8 by a rotating rod. The motor 11 is fixed on the vertical rod of the movable frame 8. The output end of the motor 11 is connected to the rotating rod at the end of the weeding roller 10. The motor 11 is connected to an external power source. The motor 11 controls the weeding roller 10 to roll on the ground to remove weeds between the two rotating plates 5. Weeding blades 12, there are several weeding blades 12, and they are fixed at equal angles on the ring wall of the weeding roller 10. Weeding wires 13 are fixed between the several weeding blades 12. The weeding roller 10 drives the weeding blades 12 to rotate, which facilitates the breaking of the surface soil first, and then the weeding wires 13 are used to cut off the roots of weeds in the soil. Adjustment component 9 includes: Guide rod 14, there are two guide rods 14, which are symmetrically fixed on the crossbar of the movable frame 8, and the guide rods 14 are movably connected through the positioning rod 4 to restrict the movement direction of the movable frame 8; Limiting ring 15, there are two limiting rings 15, and they are respectively fixed on the corresponding guide rod 14. The limiting ring 15 and the positioning rod 4 are set to abut against each other to limit the maximum movement position of the guide rod 14. An electric push rod 16 is fixed to the middle of the crossbar of the movable frame 8, and the output end of the electric push rod 16 is connected to the positioning rod 4. The electric push rod 16 is connected to an external power source. The electric push rod 16 can more accurately control the movement position of the movable frame 8. A protective plate 18 is fixed to the bottom of the crossbar of the movable frame 8, and the electric push rod 16 is located above the protective plate 18 to block splashed soil and prevent soil from contacting the electric push rod 16 and affecting its use. There are two adjusting rods 17, and their two ends are respectively screwed onto the movable frame 8 and the corresponding rotating plate 5 by rotating rods, so that the movable frame 8 moves while the adjusting rods 17 move, thereby making the rotating plate 5 rotate and adjust synchronously.

[0019] When using this utility model, the operator first starts the electric push rod 16 according to the spacing of the planted broccoli seedlings and the growth of the broccoli seedling leaves. The electric push rod 16, together with the guide rod 14, controls the movement of the moving frame 8. The moving frame 8 drives the weeding roller 10 to move. With the connection of the adjusting rod 17, the rotating plate 5 rotates synchronously, so that the limiting ball 22 moves on the limiting plate 3 until the rotating plate 5 is adjusted to a suitable tilt angle, so that the leaves of the broccoli seedlings can be blocked on the outside of the rotating plate 5. Then, the motor 11 is started. After the motor 11 controls the rotation of the weeding roller 10, the frame 1 is pulled on the soil by the pull rod matched with the frame 1. The weeding roller 10 drives the weeding blade 12 to rotate. The weeding blade 12 first breaks up the surface soil, and then cuts the weeds with the weeding wire 13, thereby improving the weeding efficiency.

[0020] Compared with the prior art, the beneficial effects of this utility model are: By tilting the rotating plate 5, the leaves of the broccoli seedlings are blocked at the position of the rotating plate 5, preventing the weeding blade 12 from contacting the broccoli seedlings, damaging the broccoli seedlings, and affecting their growth. The adjustment component 9 is set up so that the moving position of the moving frame 8 is controlled by the electric push rod 16 according to the growth of the broccoli seedlings, and the rotating plate 5 is controlled to rotate synchronously by the adjustment rod 17, so that the leaves of the broccoli seedlings at different growth stages are blocked on the outside of the rotating plate 5. A protective plate 18 is installed to block splashed soil below the electric push rod 16, preventing soil from contacting the electric push rod 16 and affecting its use. The limiting ball 22 is set. The spherical structure helps to reduce the friction between the inner wall of the limiting groove 7 and the limiting plate 3, so as to avoid damage to the limiting plate 3 and affect its service life.
