Description

Technical Field

[0001] The present application relates to the technical field of nursery weeding, and in particular to a nursery weeding device. Background Art

[0002] Nursery weeding devices can be designed in a variety of ways, with the goal of effectively controlling the growth of weeds and protecting the healthy growth of seedlings. Weeding is an important management task in nurseries or farmlands. Traditional weeding methods include manual weeding and application of herbicides. For small nurseries, manual weeding may be an effective method. Dedicated gardeners can remove weeds manually to ensure that no damage is caused to seedlings; while by spraying specific chemical herbicides, precise control of the dosage is usually required to ensure that the herb is only sprayed in the area where weeding is required. However, both methods have some disadvantages. Manual weeding requires a lot of manual labor and cannot eradicate weeds; while the use of herbicides will not only kill weeds, but also cause harm to seedlings and even pollute the environment.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a weeding device for a nursery. Figure 1-Figure 3, including a weeder hood 2, a mobile push frame 1 is fixed at the center of the top of the weeder hood 2, and a handle 3 is symmetrically welded on the outer wall of the top of the mobile push frame 1, which is convenient for holding the handle 3 to push the mobile push frame 1 to move, and a roller 14 is rotatably provided in the weeder hood 2, and a plurality of weeding knives 15 are staggeredly distributed on the outer wall of the roller 14 along the circumferential direction. The weeding knives 15 are a group of two, and the ends of the weeding knives 15 are integrally structured and provided with a curved knife head 16. Every two weeding knives 15 are symmetrically arranged, and the curved knife heads 16 can be used to cut weeds. Mobile rollers 5 are rotatably installed on the outer walls of both sides of the weeder hood 2 to improve portability. A motor is installed on one side of the inner wall of the weeder hood 2, and the output end of the motor is transmitted to the roller 14, so that the roller 14 can be driven to rotate for weeding, and a baffle 13 is fixedly connected to the outer wall of the front end of the weeder hood 2 to prevent splashing.

[0020] like Figure 1-Figure 2 As shown, a fixed frame 4 is provided at the front end of the mobile push frame 1, and the fixed frame 4 is fixed to the top of the mobile push frame 1. A sliding cavity is opened inside the fixed frame 4, and a servo motor is installed at the top of the sliding cavity. The output end of the servo motor is connected to a screw rod 7 for transmission, and a slider 8 adapted to the sliding cavity is slidably installed outside the screw rod 7. As the screw rod 7 rotates, the slider 8 can be driven to perform linear reciprocating motion in the sliding cavity.

[0021] A mounting frame 9 is slidably provided in the fixing frame 4, a weeding shovel frame 6 is rotatably installed inside the mounting frame 9, and one end of the mounting frame 9 close to the fixing frame 4 is fixed to the outer wall of the slider 8, so that the mounting frame 9 can be adjusted in height along with the slider 8, a rotating cavity is provided inside the mounting frame 9, a connecting head 11 is rotatably installed in the rotating cavity, one end of the connecting head 11 is welded to the top of the weeding shovel frame 6, driving the weeding shovel frame 6 to adjust the weeding height accordingly, and a plurality of comb teeth 12 are equidistantly welded on the bottom of the weeding shovel frame 6, through which large weeds and gravel can be removed in advance;

[0022] In addition, one end of the connecting head 11 away from the weeding shovel frame 6 extends to the bottom of the mounting frame 9, and a support spring 10 is connected between the mounting frame 9 and the inner wall of the connecting head 11 for support. As the comb teeth 12 are subjected to force when working, the support spring 10 will be squeezed to move in the mounting frame 9 to avoid rigid collision.

[0023] The implementation principle of a nursery weeding device in the embodiment of the present application is as follows: when in use, the movable push frame 1 is pushed by the handle 3, thereby driving the weeder cover 2 to move on the ground for weeding, the servo motor inside the fixed frame 4 is started to drive the screw rod 7 to rotate, and the slider 8 then performs a linear reciprocating motion in the fixed frame 4, and then pushes the weeding shovel frame 6 through the mounting frame 9 to adjust the weeding height. When the slider 8 moves downward, the comb teeth 12 are pushed to move downward close to the ground, so that larger weeds and gravel on the ground can be removed, and as the comb teeth 12 are subjected to working force, the connecting head 11 will be driven to rotate in the mounting frame 9 to squeeze the support spring 10 for buffering, thereby avoiding hard collision, and then the motor inside the weeder cover 2 is started to drive the roller 14 to rotate, driving the weeding knife 15 to roll and contact the weeds on the ground, and the ground weeds are cut off by the curved knife head 16 to complete the weeding work, and the baffle 13 can limit the front to avoid hard collision.
