Description

Technical Field

[0001] This utility model belongs to the technical field of landscaping devices, specifically relating to a landscaping weeding device. Background Technology

[0002] Currently, vertical curb stones are often installed along the sides of garden paths. Weeds easily grow in the joints between the path and the curb stones, as well as in adjacent gaps. If large weeding equipment is used for overall treatment, its mechanical structure is ill-suited to the narrow spaces, and the equipment is prone to collisions with the vertical curb stones during operation. This not only damages the blades or transmission mechanisms, but for equipment that relies on high-speed rotating blades or weeding ropes, frequent impacts with the stones cause rapid wear of working parts, significantly reducing the equipment's lifespan. Furthermore, existing professional weeding equipment is bulky and heavy, making it inconvenient for garden maintenance personnel to carry for routine maintenance. Traditional manual weeding tools, on the other hand, are inefficient and fail to thoroughly remove weed roots from gaps.

[0003] Therefore, this utility model proposes a garden greening weeding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a garden and landscaping weeding device that can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows: This utility model provides a garden greening weeding device, including a main tube and an adjustment mechanism set inside the main tube. The adjustment mechanism is equipped with a grouting curved knife. A first bending arm is fixedly set at the bottom of the main tube, and a roller is rotatably installed at the free end of the first bending arm. Two positioning screw holes are opened on the main tube, and a main positioning component and a secondary positioning component for limiting the rotation of the adjustment mechanism are threaded into the two positioning screw holes. The main tube is provided with two mounting fasteners, and the main tube is provided with screw holes that are symmetrically offset from the positioning screw holes by 180° in the axial direction and threadedly engaged with the two mounting fasteners. A hand handle is fitted inside the main tube and is secured by the mounting fasteners.

[0006] Preferably, the adjustment mechanism includes an inner sleeve that fits with the clearance inside the main tube, and a second bending arm that is symmetrical to the first bending arm is fixedly disposed inside the inner sleeve, and a roller is rotatably mounted on the free end of the second bending arm. A fixing block is fixedly installed on the second bending arm, and the bottom surface of the fixing block has a slot for engaging with the back of the grouting bend. Both the slot and the grouting bend are set to be vertically inclined at 8°. A bolt is fixedly installed at the root of the grouting bend, and the bolt is sleeved in the sleeve hole ear plate and is secured by a nut to prevent it from coming off.

[0007] Preferably, the inner sleeve has two first sleeve holes distributed at 90°, both of which are fitted with the auxiliary positioning component. The inner sleeve has a second sleeve hole in the circumferential direction corresponding to the two first sleeve holes. The angle between the second sleeve hole and an adjacent first sleeve hole is 30°, and the second sleeve hole is also fitted with the auxiliary positioning component.

[0008] Preferably, the inner sleeve has a rotation limiting hole that corresponds to the two first sleeve holes in the circumferential direction. The arc opening length of the rotation limiting hole is set to 110°, and the rotation limiting hole is sleeved with the main positioning component.

[0009] Preferably, the inner sleeve has a rotating hole that corresponds to the inner sleeve of the first bent arm inside the main tube.

Detailed Implementation

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1-4 As shown, a garden greening weeding device includes a main tube 1 and an adjustment mechanism 2 installed inside the main tube 1. The adjustment mechanism 2 is equipped with a grouting curved blade 3. A first bending arm 4 is fixedly installed at the bottom inside the main tube 1, and a roller is rotatably installed at the free end of the first bending arm 4. Two positioning screw holes 5 are opened on the main tube 1. The two positioning screw holes 5 are internally threaded with a main positioning component 6 and a secondary positioning component 61 for limiting the rotation of the adjustment mechanism 2. The main positioning component 6 and the secondary positioning component 61 are wing bolts 31. Two mounting fasteners 7 are provided on the main tube 1, and the main tube 1 has screw holes that are symmetrically offset from the positioning screw holes 5180° in the axial direction and threadedly engaged with the two mounting fasteners 7. A hand handle is fitted inside the main tube 1 and is fastened by the mounting fasteners 7, which are wing bolts 31.

[0017] As an optional implementation, the adjustment mechanism 2 includes an inner sleeve 21 that is clearance-fitted with the inner sleeve 1. A second bending arm 22, which is symmetrical to the first bending arm 4, is fixedly installed inside the inner sleeve 21. A roller is rotatably mounted on the free end of the second bending arm 22. A fixing block 23 is fixedly installed on the second bending arm 22. The bottom surface of the fixing block 23 has a slot 23a that engages with the back of the grouting blade 3. Both the slot 23a and the grouting blade 3 are set to be vertically inclined at 8°. A bolt 31 is fixedly installed at the root of the grouting blade 3. The bolt 31 is sleeved in the ear plate 25 and is secured by a nut to prevent it from coming off. The ear plate 25 is fixedly installed on the lower side of the end of the inner sleeve 21 so that the grouting blade 3 can tilt and slide through the gap, thereby improving the mobile weeding effect.

[0018] See attached document Figure 2 and attached Figure 3 The inner sleeve 21 has two first sleeve holes 21a distributed at 90°. Both first sleeve holes 21a are fitted with the auxiliary positioning component 61. The inner sleeve 21 has a second sleeve hole 21b in the circumferential direction corresponding to the two first sleeve holes 21a. The angle between the second sleeve hole 21b and the adjacent first sleeve hole 21a is 30°. The second sleeve hole 21b is also fitted with the auxiliary positioning component 61, so that the two first sleeve holes 21a and the second sleeve hole 21b form 90° and 120° rotation angle limits on the positioning screw hole 5 on the main tube 1, which facilitates the first bending arm 4 and the grouting bend 3 to form corresponding angle support. It is suitable for weeding operations at vertical seams. The auxiliary positioning component 61 is a wing bolt 31.

[0019] See attached document Figure 4 The inner sleeve 21 is provided with a rotation limiting hole 21c that corresponds circumferentially to the two first sleeve holes 21a. The arc opening length of the rotation limiting hole 21c is set to 110°, and the rotation limiting hole 21c is sleeved with the main positioning member 6 so that the main positioning member 6 restricts the rotation angle of the rotation limiting hole 21c in a circumferential manner, thereby achieving anti-detachment protection when the inner sleeve 21 is rotated and adjusted.

[0020] Furthermore, the inner sleeve 21 is provided with a rotating movable hole 21d that fits inside the first bent arm 4 inside the main tube 1. The rotating movable hole 21d is set to be open corresponding to the free end on the outer side of the inner sleeve 21, and the arc opening width of the rotating movable hole 21d is set to 110°. The length of the rotating movable hole 21d is set to be greater than the length of the first bent arm 4 inside the main tube 1, so that the circumferential rotation distance of the rotating movable hole 21d is consistent with that of the rotating limiting hole 21c, so as to avoid the obstruction effect of the first bent arm 4 on the rotation adjustment of the inner sleeve 21. The rotating movable hole 21d has an inner sleeve through hole 21e that communicates with the end face. The opening width of the inner sleeve through hole 21e is set to be greater than the radius of the first bent arm 4 so that when the inner sleeve 21 is inserted into the main body tube 1, the inner sleeve 21 can be inserted and assembled through the inner sleeve through hole 21e.

[0021] Furthermore, two inner support plates 24 are fixedly installed inside the inner sleeve 21. The two inner support plates 24 are located on opposite sides of the first sleeve hole 21a and the rotation limiting hole 21c, respectively, to provide fixed support for the shape formed inside the inner sleeve 21, so as to facilitate the insertion operation of the inner sleeve 21 and the main tube 1.

[0022] Using the above structure, firstly, loosen the secondary positioning component 61 to release the rotational constraint on the adjustment mechanism 2; then, the operator holds the main tube 1 and rotates the inner sleeve 21 to drive the second bending arm 22 and the grouting blade 3 to adjust their angles. When vertical weed cutting is required, rotate the inner sleeve 21 until the secondary positioning component 61 is aligned with the corresponding first sleeve hole 21a or second sleeve hole 21b—at this time, the second bending arm 22 forms a 90° or 120° angle with the first bending arm 4, and the grouting blade 3 is adjusted accordingly to the optimal working angle; then tighten the secondary positioning component 61 to achieve angle positioning, and cooperate with the main positioning component 6 to complete circumferential locking. The entire adjustment process is achieved through the butterfly bolt 31 for quick tightening and loosening, without the need for additional tools, which ensures the stability of the structure during operation and achieves the effects of flexible adaptation to multiple angles and convenient portability.
