Description

Technical Field

[0001] This utility model belongs to the field of pruning tool technology, and in particular relates to a forestry pruning tool. Background Technology

[0002] Forest pruning is a crucial aspect of forestry management. Proper pruning can regulate tree growth, reduce pests and diseases, and improve timber yield and quality, thus playing a vital role in the healthy development of forestry. However, traditional forestry pruning tools and existing pruning equipment have long suffered from numerous problems in practical applications, failing to meet the demands of efficient, precise, and safe pruning in modern forestry. In traditional pruning operations, manual pruning shears and hand saws are commonly used. While manual pruning shears offer relative flexibility, they are only suitable for pruning thinner branches and are inadequate for larger branches, requiring significant physical exertion and resulting in low efficiency. Hand saws, while effective for pruning thicker branches, are less effective in this regard.

[0003] According to a public disclosure of a forestry pruning tool (Publication No.: CN 222786471 U), it includes a scissor device and an arm assembly fixedly installed at the lever arm end of the scissor device. The arm assembly includes: a first arm, one end of which is fixedly connected to the lever arm end of the scissor device; and a second arm, movably disposed at one end of the first arm, with a limiting block movably provided at one end of the second arm, and a limiting groove formed at the end of the first arm opposite to the second arm. This utility model, by setting the arm assembly of the pruning tool as a split structure composed of a first arm and a second arm, allows the second arm to rotate at the end of the first arm. The retractable limiting block on the end face of the second arm, in conjunction with the limiting groove on the end face of the first arm, enables the second arm to rotate, fold, unfold, and lock at the end of the first arm. This ensures ease of use while facilitating folding and storage, thereby improving the convenience of using the pruning tool.

[0004] However, the pruning shears in the aforementioned patent require workers to use tremendous force to engage the shears when pruning thick branches, while larger branches are easier for workers to remove using the pruning shears, which needs improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a forestry pruning tool that uses the driving force of a motor to drive components such as a rotating shaft, a first sprocket, a connecting shaft, a second sprocket, a cutting chain, a first cutting wheel, and a second cutting wheel to work together. This enables the motor, which runs through the side of the fixed plate, to start and drive the rotating shaft, which is fixed at the end of the output shaft, to rotate. The rotation of the rotating shaft then drives the first sprocket, which is fixed at the other end, to rotate, thus solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a forestry pruning tool, comprising a pruning tool body, a large branch cutting mechanism provided on the side of the pruning tool body, the large branch cutting mechanism including a fixing plate, the fixing plate being fixedly connected to the side of the pruning tool body, a motor passing through the side of the fixing plate, a rotating shaft being fixedly connected to the end of the output shaft of the motor, a first sprocket being fixedly connected to the circumferential surface of the rotating shaft, a cutting chain being engaged on the circumferential surface of the first sprocket, a connecting shaft being rotatably connected to the side of the fixing plate, and a second sprocket being fixedly connected to the end of the connecting shaft away from the fixing plate.

[0008] Furthermore, a first cutting wheel is fixedly connected to the side of the first sprocket, and a second cutting wheel is fixedly connected to the side of the second sprocket. The design of the first cutting wheel and the second cutting wheel is conducive to cutting off thick branches more effectively.

[0009] Furthermore, the circumferential surface of the second sprocket is engaged with the cutting chain, and the side cross-section of the fixing plate is set to L-shape. The design of the fixing plate facilitates the addition of other components, thereby improving the practicality of the pruning tool body.

[0010] Furthermore, a support mechanism is provided on the side of the fixing plate. The support mechanism includes a torsion spring rod, which is rotatably connected to the side of the fixing plate. A sleeve is fixedly connected to the circumferential surface of the torsion spring rod, and a support plate is fixedly connected to the circumferential surface of the sleeve. The above design is beneficial for stabilizing and more efficiently cutting thick branches.

[0011] Furthermore, a contact rod is fixedly connected to the circumferential surface of the sleeve. The design of the contact rod facilitates the upward arc movement of the support plate, thus stabilizing it during the cutting of thick branches.

[0012] Furthermore, the side cross-section of the support plate is set to L-shape, which helps to stabilize the branches during the cutting process.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes the driving force of a motor to activate components such as a rotating shaft, a first sprocket, a connecting shaft, a second sprocket, a cutting chain, a first cutting wheel, and a second cutting wheel. This activates a motor that runs through the side of a fixed plate, thereby rotating a rotating shaft fixed at the end of an output shaft. The rotation of the rotating shaft causes the first sprocket fixed at the other end to rotate, which in turn causes the meshing cutting chain to move. The movement of the cutting chain then causes the meshing second sprocket to rotate. This allows for the pruning of thick branches.

[0015] This invention utilizes the movement force of the contact rod to drive the torsion spring rod, sleeve, support plate, and other components to work together. When a worker is cutting off a large branch, the worker presses down on the contact rod fixed to the circumference of the sleeve, causing it to move downward. The downward movement of the contact rod causes the sleeve to be subjected to a downward rotational force, which in turn drives the torsion spring rod rotating on the side of the fixed plate. When the torsion spring rod rotates, it ensures that the branch makes stable contact with the cutting wheel during the pruning process.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 As shown, this utility model is a forestry pruning tool, including a pruning tool body 1. A large branch cutting mechanism 2 is provided on the side of the pruning tool body 1. The large branch cutting mechanism 2 includes a fixing plate 21, which is fixedly connected to the side of the pruning tool body 1. A motor 22 passes through the side of the fixing plate 21. A rotating shaft 23 is fixedly connected to the end of the output shaft of the motor 22. A first sprocket 24 is fixedly connected to the circumferential surface of the rotating shaft 23. A cutting chain 27 is engaged on the circumferential surface of the first sprocket 24. A connecting shaft 25 is rotatably connected to the side of the fixing plate 21. A second sprocket 26 is fixedly connected to the end of the connecting shaft 25 away from the fixing plate 21.

[0027] As shown in the figure, a first cutting wheel 28 is fixedly connected to the side of the first sprocket 24, and a second cutting wheel 29 is fixedly connected to the side of the second sprocket 26. The design of the first cutting wheel 28 and the second cutting wheel 29 is conducive to cutting off thick branches more effectively.

[0028] As shown in the figure, the circumferential surface of the second sprocket 26 is engaged with the cutting chain 27, and the side section of the fixing plate 21 is set to L-shape. The design of the fixing plate 21 is conducive to the addition of other components, which improves the practicality of the pruning tool body 1.

[0029] As shown in the figure, a support mechanism 3 is provided on the side of the fixing plate 21. The support mechanism 3 includes a torsion spring rod 31, which is rotatably connected to the side of the fixing plate 21. A sleeve 32 is fixedly connected to the circumferential surface of the torsion spring rod 31, and a support plate 33 is fixedly connected to the circumferential surface of the sleeve 32. The above design is beneficial to make the cutting of thick branches more stable and efficient.

[0030] As shown in the figure, a contact rod 34 is fixedly connected to the circumferential surface of the sleeve 32. The design of the contact rod 34 is conducive to the upward arc movement of the support plate 33, which stabilizes it during the cutting of thick branches.

[0031] As shown in the figure, the side section of the support plate 33 is set to L-shape, which helps to stabilize the branches during the cutting process.

[0032] A specific application of this embodiment is as follows: When it is necessary to prune thick branches, the worker places the branch on the top of the support plate 33, then the branch contacts the cutting chain 27 and the surfaces of the first cutting wheel 28 and the second cutting wheel 29. Finally, the motor 22 passing through the side of the fixed plate 21 is started, thereby driving the rotating shaft 23 fixed at the end of the output shaft to rotate. The rotation of the rotating shaft 23 drives the first sprocket 24 fixed at the other end to rotate. The rotation of the first sprocket 24 drives the intermeshing cutting chain 27 to move. The movement of the cutting chain 27 drives the intermeshing second sprocket 26 to rotate, thereby making the cutting chain 27 move stably to cut the branch. Subsequently, when the first sprocket 24 rotates... The first cutting wheel 28, fixed on the side, rotates, while the second sprocket 26 rotates, causing the second cutting wheel 29, also fixed on the side, to rotate and cut the branches. Finally, when the worker cuts the thick branches, the worker presses down on the contact rod 34, which is fixed on the circumference of the sleeve 32, and moves it downward. The downward movement of the contact rod 34 causes the sleeve 32 to be subjected to a downward rotational force, which in turn causes the torsion spring rod 31, which rotates on the side of the fixed plate 21, to rotate. When the torsion spring rod 31 rotates, it causes the sleeve 32 to rotate. The rotation of the sleeve 32 causes the support plate 33 on the circumference to move upward in an arc, so that the branches can more closely contact the cutting chain 27, the first cutting wheel 28, and the second cutting wheel 29.
