Abstract
Description
Technical Field
[0001] This utility model relates to the field of garden maintenance and green plant pruning technology, specifically a green plant pruning device for garden maintenance. Background Technology
[0002] Lawn mowing is crucial in garden maintenance. Its necessity lies in the fact that regularly removing the tips of grass blades effectively stimulates tillering, inhibits competition from weeds, reduces the breeding of pests and diseases, and enhances the plant's resistance, thereby maintaining the healthy vitality of the lawn. Its core purpose is to control the height and density of the lawn, create a smooth and uniform landscape surface, form beautiful decorative stripes, and ensure that it meets the functional requirements of sports fields or safe passage requirements. Its fundamental significance is to improve the ecological quality and ornamental value of garden green spaces, create clean and beautiful public spaces and living environments, and satisfy people's pursuit of a natural, comfortable, and elegant outdoor living atmosphere.
[0003] Current technology has the following shortcomings: Currently, hand-push rotary lawnmowers are commonly used for lawn mowing. This equipment is favored for its compact structure, flexible operation, and precise mowing, especially for efficiently handling common upright weeds. However, this equipment has a significant performance weakness: after heavy rain or strong winds, weeds in the lawn often flatten and lie flat due to external forces. At this time, the rotary blades struggle to form effective rigid contact and shearing engagement with the grass blades close to the ground during movement. Instead, the rolling action of the blades further compacts the already flattened weeds, resulting in many grass stems and leaves not being cut but simply passing over the blades. This ultimately leads to uneven mowing and frequent omissions, severely affecting the overall mowing quality and landscape effect. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a green plant trimming device for garden maintenance, which solves the problem that it is difficult to trim fallen weeds.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a green plant trimming device for garden maintenance, comprising an integrated protective shell, a wheel body, a handle for easy gripping and pushing, and a roller blade for cutting weeds, characterized in that: an extension shaft is provided at the outer end of the wheel body, a ratchet disc one and a ratchet disc two are sleeved on the outer side of the extension shaft, and a paddle is provided on the outer side of the ratchet disc one. When the paddle is driven by the wheel body through the connection between the extension shaft and the wheel body, it will swing upwards through the rotation of the wheel body.
[0006] As a preferred embodiment of this utility model, the ratchet disc is fixedly installed on the outside of the extension shaft, and a disc-shaped structure is provided at the end of the extension shaft and inverted on the outside.
[0007] As a preferred embodiment of this utility model, the paddle adopts a multi-toothed rake-like structure.
[0008] As a preferred technical solution of this utility model, the inner side of the integrated protective shell is provided with a connecting ring for supporting installation, a central shaft for transmission is inserted through the middle of the connecting ring, a motor for providing driving force is provided at the side end of the central shaft, and the hob is sleeved on the outside of the central shaft through the two side ring structures.
[0009] As a preferred technical solution of this utility model, the extension shaft serves as the support shaft of the wheel body, and a rotatable connection is established between the other end of the connecting ring and its end. The extension shaft on one side of the motor is rotatably connected to the end of the motor.
[0010] As a preferred technical solution of this utility model, a spring is sleeved between the ratchet disk one and the disc-shaped structure at the end of the extension shaft to continuously apply lateral pressure to the ratchet disk one and keep the ratchet disk one in close contact with the ratchet disk two. The ratchet disk one and the ratchet disk two mesh with each other. When the extension shaft drives the ratchet disk two connected to it, it can only drive the ratchet disk one in one direction.
[0011] Compared with the prior art, this utility model provides a green plant pruning device for garden maintenance, which has the following beneficial effects:
[0012] A green plant trimming device for garden maintenance controls the cutting direction of weeds by gripping a handle. The rotary cutter achieves high-speed rotation and cutting through a central shaft driven by a motor. When the operator grips the handle and pushes forward to cut the weeds, if the weeds are upright, continued pushing is sufficient. The front blade briefly bends the upright weed upon contact, and after passing through, the weeds rebound and return to their original position due to the resilience of their fibers, at which point the rotary cutter quickly completes the cutting. If the weeds to be cut are affected by the environment, such as rain or strong winds, and are in a flattened state, the operator can first push the wheel forward to approach the weeds, then pull the handle backward. When the wheel moves backward, it will enter the transmission state through the meshing of ratchet disc one and ratchet disc two. The rotation of the extension shaft will cause ratchet disc one and ratchet disc two to rotate synchronously. Thus, the paddle will lift up after being inserted into the root of the flattened weeds, and the lifting action will complete the lifting of the flattened weeds. At this time, the operator can push the handle forward again to complete the cutting before the weeds flatten.
[0013] Through the above settings and processes, this device, compared to existing lawn and green plant trimming devices, adds a lever and links the lifting action of the lever to the movement of the wheel. It can quickly lift up fallen weeds simply by changing the direction of the wheel's travel, improving the weed trimming effect with a convenient operation method. It also eliminates the need for manual operation of the trimming machine while cleaning up fallen weeds, thus improving the comfort of operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4 In this embodiment: a green plant trimming device for garden maintenance includes an integrated protective shell 1, a wheel body 2, a handle 3 for easy gripping and pushing, and a roller blade 7 for cutting weeds. An extension shaft 9 is provided at the outer end of the wheel body 2. A ratchet disc 10 and a ratchet disc 2 11 are sleeved on the outer side of the extension shaft 9. A paddle 8 is provided on the outer side of the ratchet disc 10. When the paddle 8 is driven by the wheel body 2 through the connection between the extension shaft 9 and the wheel body 2, it will swing upward through the rotation of the wheel body 2. When the paddle 8 swings upward, it can lift the grass that has been flattened by rain or wind, so that the roller blade 7 can cut the weeds accordingly.
[0021] Ratchet disc 21 is fixedly installed on the outside of extension shaft 9, and a disc-shaped structure is provided at the end of extension shaft 9 and inverted on the outside (e.g. Figure 4 (As shown).
[0022] The paddle 8 uses a multi-toothed rake-like structure (such as...). Figure 1 As shown in the figure, the parallel grooves can effectively hook up bent and fallen weeds. They can also be any structure that can hook up weeds, such as hook-shaped or sheet-shaped.
[0023] To ensure that the high-speed rotation of the hob 7 and the slow rotation of the wheel 2 do not interfere with each other, a connecting ring 4 for support and installation is snapped into the inner side of the integrated protective shell 1. A central shaft 5 for transmission is inserted through the middle of the connecting ring 4. A motor 6 for providing driving force is set on the side end of the central shaft 5. The hob 7 is sleeved on the outside of the central shaft 5 through the ring structure on both sides. Thus, the motor 6 drives the hob 7 to rotate at high speed through the central shaft 5.
[0024] The extension shaft 9 serves as the support shaft for the wheel body 2, and is rotatably connected to its end from the other end of the connecting ring 4. The extension shaft 9 on one side of the motor 6 is rotatably connected to the end of the motor 6. Thus, the rotation of the central shaft 5 is independent of the rotation of the wheel body 2 and the extension shaft 9.
[0025] Since the wheel 2 is linked to the lifting of the lever 8 via the extension shaft 9, to prevent affecting the normal forward movement of the wheel 2, a disc-shaped structure (such as...) is installed at the end of the ratchet disc 10 and the extension shaft 9. Figure 4 A spring 12 is fitted between the ratchet discs (as shown). The spring 12 is used to apply lateral pressure to the ratchet disc 10 at all times, and to keep the ratchet disc 10 in close contact with the ratchet disc 11. Thus, through the mutual meshing of the ratchet discs 10 and 11, the extension shaft 9 can only drive the ratchet disc 10 when it drives the ratchet disc 11 connected to it to rotate in one direction. The specific transmission steps are as follows:
[0026] When the operator holds the handle 3 and pulls it backward, the wheel 2 rolls backward. At this time, the wheel 2 can drive the ratchet disc 10 through the extension shaft 9 and the ratchet disc 2 11, thereby lifting the paddle 8.
[0027] When the operator holds the handle 3 and pushes it forward, the wheel 2 rolls forward. At this time, since the meshing connection between the second ratchet disc 11 and the first ratchet disc 10 is only for one-way transmission, the second ratchet disc 11 will only continuously slip teeth on the side end of the first ratchet disc 10. Through the pressure of the spring 12, the first ratchet disc 10 will still be in close contact with the second ratchet disc 11 after each slip. Therefore, when the wheel 2 rolls forward, the paddle 8 does not move.
[0028] In this embodiment, the operator controls the cutting direction of the weeds by holding the handle 3. The roller 7 achieves high-speed rotation and cutting through the driving force provided by the motor 6 and transmitted through the central shaft 5. When the operator holds the handle 3 and pushes forward to perform the weed cutting operation, if the weeds are normally upright, only continuous pushing is needed. When the front blade 8 contacts the upright weeds, it will briefly bend them. After passing the weeds, the weeds will rebound and return to their original position due to the toughness of their own fibers. At this time, the roller 7 quickly completes the cutting of the weeds. If the weeds to be cut are affected by the environment, such as rain or strong winds, and are in a flattened state, the operator can first push the wheel 2 forward to approach the weeds, then pull the handle 3 backward. When the wheel 2 moves backward, it will enter the transmission state through the meshing of ratchet disc 10 and ratchet disc 21. The rotation of the extension shaft 9 will cause ratchet disc 10 and ratchet disc 21 to rotate synchronously. As a result, the paddle 8 will lift up after being inserted into the root of the flattened weeds, and the lifting action will complete the lifting of the flattened weeds. At this time, the operator can push the handle 3 forward again to complete the cutting before the weeds flatten.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
