[0024] Combined with appendix Figures 1-4 An adjustable weeding hoe with a tree guard for forest tending includes a hoe handle assembly, a hoe head assembly, and a tree guard assembly.

[0025] The hoe assembly is connected to one end of the hoe handle assembly; the tree guard assembly is sleeved on the hoe handle assembly and can move along its length. The tree guard assembly includes an arc-shaped baffle 10 protruding towards the hoe assembly, which is used to protect the roots of trees during weeding.

[0026] Example 1

[0027] In one embodiment of this utility model, such as Figures 1-2As shown, the hoe handle assembly includes a main rod 2 and an adjusting sleeve 1 sleeved on the main rod 2. The main rod 2 is slidably disposed in the hollow part of the adjusting sleeve 1. A fixing bolt 3 with its end abutting against the side wall of the adjusting sleeve 1 is threadedly connected to the side wall of the main rod 2. Specifically, the main rod 2 is a round metal rod, and can be further designed as a hollow structure to reduce the overall weight. The adjusting sleeve 1 is a tubular component closed at one end, with its inner diameter slightly larger than the outer diameter of the main rod 2 to achieve a smooth sliding fit. The fixing bolt 3 is screwed vertically into the threaded hole on the side wall of the adjusting sleeve 1, and its end can be equipped with a rubber gasket. When adjusted to the required length, the fixing bolt 3 is tightened, and its end will press tightly against the side wall of the main rod 2. Static friction prevents relative movement between the main rod 2 and the adjusting sleeve 1, thereby achieving stepless adjustment and reliable fixation of the total length of the hoe handle, adapting to the usage needs of different operators.

[0028] In one embodiment of this utility model, such as Figures 1-2 and Figure 4 As shown, the hoe assembly includes a U-shaped connecting frame 5 fixedly installed at one end of the main shaft 2. A connecting post 16 is rotatably provided on the U-shaped connecting frame 5, and a hoe blade 6 is provided on the connecting post 16. Several limiting holes 12 are arranged around the end face of the connecting post 16 around its rotating shaft. A limiting bolt 11 is threadedly connected to the U-shaped connecting frame 5 and can be inserted into any of the limiting holes 12. Specifically, the U-shaped connecting frame 5 is fixed to the end of the main rod 2 by welding or fasteners. The connecting column 16 is horizontally set between the two arm plates of the U-shaped connecting frame 5 through bearings or simple shaft hole cooperation, so that the connecting column 16 can rotate around its own axis. The hoe 6 is fixedly installed on the side of the connecting column 16. On the end face of the connecting column 16, twelve limiting holes 12 are evenly distributed around its center. The limiting bolt 11 passes through the threaded hole on one of the arm plates of the U-shaped connecting frame 5. When it is necessary to adjust the angle of the hoe 6, loosen the limiting bolt 11 to disengage it from the current limiting hole 12, and then rotate the hoe 6 to a new angle. Then tighten the limiting bolt 11 so that its front end is inserted into the aligned limiting hole 12, so as to realize the rapid and precise adjustment of multiple fixed angles of the hoe 6 to cope with different weeding postures and ground conditions.

[0029] In one embodiment of this utility model, combined with Figures 1-2As shown, the tree protection baffle assembly includes a slider 4 slidably mounted on the main rod 2. A tension spring 7 is provided between the slider 4 and the U-shaped connecting frame 5. The slider 4 is provided with a connecting arm 8, and an arc-shaped baffle 10 is provided at the end of the connecting arm 8. Specifically, the slider 4 has a through hole in the center, is sleeved on the main rod 2, and can slide freely along the main rod 2. One end of the tension spring 7 is connected to the slider 4, and the other end is connected to the U-shaped connecting frame 5. In the natural state, the tension of the tension spring 7 drives the slider 4 to move the arc-shaped baffle 10 towards the hoe. When the operator pushes the arc-shaped baffle 10 towards the tree trunk, it needs to overcome the tension of the tension spring 7. At this time, the arc-shaped baffle 10 is in close contact with the tree roots. When weeding, this design allows the baffle to dynamically maintain contact with the tree as the hoe moves, providing continuous protection, and automatically resets after being removed.

[0030] In one embodiment of this utility model, such as Figure 4 As shown, the connecting arm 8 is connected to the slider 4 via a damping shaft 15. Specifically, the damping shaft 15 has an internal friction structure that allows it to remain in any rotational position when not subjected to external force or subjected to a small external force. This structure allows the operator to manually rotate the connecting arm 8 and the arc-shaped baffle 10 horizontally to the desired position. The damping shaft 15 provides sufficient resistance to keep it at the set angle and prevents it from swinging arbitrarily due to its own weight or slight collisions, thereby ensuring that the baffle can accurately protect the tree from different working directions.

[0031] In one embodiment of this utility model, such as Figure 2 As shown, the end of the connecting arm 8 is provided with a ball socket 9, and the arc-shaped baffle 10 is provided with a ball head rod 13 that cooperates with the ball socket 9. Specifically, the ball socket 9 has a hemispherical cavity inside, and the ball head of one end of the ball head rod 13 is nested in it, forming a ball hinge connection. This allows the arc-shaped baffle 10 to not only adjust its pitch angle around the center of the ball within a certain cone angle range, but also to make slight lateral swings. The arc-shaped baffle 10 can adaptively fine-tune its concave surface to fit the root surface as closely as possible, achieving a better wrapping and protective effect.

[0032] In one embodiment of this utility model, such as Figure 2 As shown, a flexible buffer layer 14 is provided on the concave surface of the arc-shaped baffle 10. Specifically, the flexible buffer layer 14 can be made of soft and elastic materials such as rubber, foam, silicone, or felt, and is fixed to the concave surface of the arc-shaped baffle 10 by bonding or covering. This buffer layer can effectively prevent the bark from being scratched or indented when the baffle made of metal or hard plastic material is directly rubbed or impacted, further improving the protective performance of the equipment.

[0033] An adjustable weeding hoe with a tree-protecting baffle for forest tending, according to an embodiment of the present invention.

[0034] When in use, the operator can first loosen the fixing bolt 3 according to their own height and working comfort, slide the main rod 2 and the adjusting sleeve rod 1 to a suitable total length, and then tighten the fixing bolt 3 to lock it.

[0035] Subsequently, depending on the type of weeds to be removed and the terrain, loosen the limiting bolt 11, rotate the connecting column 16 to drive the hoe blade 6 to rotate to the optimal working angle, such as flat scraping, oblique planing or vertical cutting, and align the limiting bolt 11 and insert it into the corresponding limiting hole 12 to fix the angle of the hoe blade 6.

[0036] When weeding near trees, swing the hoe to remove weeds, and point the arc-shaped baffle 10 of the tree protection baffle assembly toward the tree roots. When close to the tree, its concave surface can protect the base of the trunk to avoid damaging the tree. The arc-shaped baffle 10 will always tend to move toward the hoe under the action of the tension spring 7, so as to protect the tree without affecting the device's clearing of weeds in the area near the tree.

[0037] In this embodiment, when there is no need to protect the trees, the tree protection baffle assembly can be removed from the main rod 2 by separating the adjusting sleeve 1 from the main rod 2 and disconnecting the tension spring 7 from the U-shaped connecting frame 5. The hoe arm assembly and hoe head assembly can then be retained for weeding operations.

[0038] Example 2

[0039] Combination Figure 5 As shown, in this embodiment, based on embodiment 1, a downwardly extending blade 17 is provided at the bottom end of the arc-shaped baffle 10, so that the arc-shaped baffle 10 also has the function of a hoe 6, which also facilitates the removal of weeds at the edge of the tree roots.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
