Description
Technical Field
[0001] This invention belongs to the field of agricultural implements technology, specifically relating to a pruning device for forest tending. Background Technology
[0002] Landscape greening refers to the creation of beautiful natural environments and recreational areas within a specific region through engineering techniques and artistic means, such as modifying the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. Landscape greening typically requires pruning of vegetation. Currently, pruning devices on the market mainly include power tools and manual tools. However, both power and manual tools are relatively inconvenient for pruning branches at heights. When the pruning tool is raised using a pole, it is easy for the tool to interfere with branches not intended for pruning, affecting pruning efficiency. Furthermore, during pruning, relative slippage between the tool and the branch being pruned can occur, impacting efficiency and creating safety hazards. Summary of the Invention

[0024] The present invention will now be further described with reference to the accompanying drawings.
[0025] A pruning device for forest tending includes a pruning mechanism 1, a lifting rod 2, and a pruning drive mechanism 3. The pruning mechanism 1 is used to fix branches and prune the fixed branches. The pruning mechanism 1 is slidably mounted on the lifting rod 2, and the height of the pruning mechanism 1 can be adjusted according to the height of the branches to be pruned. The pruning drive mechanism 3 is fixed on the lifting rod 2 and connected to the pruning mechanism 1. The pruning drive mechanism 3 drives the pruning mechanism 1 to rise and fall, fix branches, and perform pruning operations.
[0026] During the pruning process, the pruning mechanism 1 is first attached to the branch to be pruned, which facilitates the subsequent pruning of the branch by the pruning mechanism 1. On the one hand, it improves the efficiency of branch pruning, and on the other hand, it prevents the pruning mechanism 1 from moving during the branch pruning process, reduces the risk of the pruning mechanism 1 falling during the pruning process, and improves the usability and installability of this pruning device.
[0027] The pruning mechanism 1 includes a chainsaw 1-1, a mounting base 1-2, and a branch fixing component. The mounting base 1-2 is slidably mounted on the lifting rod 2. The chainsaw 1-1 is fixedly mounted on the mounting base 1-2. The branch fixing component is swayably mounted on the mounting base 1-2 and is adapted to the chainsaw 1-1. That is, after the branch fixing component swings, the branch fixing component and the chainsaw 1-1 are located on the upper and lower sides of the branch, respectively, thereby fixing the pruning mechanism 1 to the branch to be pruned. A button for controlling the operation of the chainsaw 1-1 is provided on the lifting rod 2.
[0028] The mounting base 1-2 has a mounting cavity in the middle, and the tree branch fixing component is arranged in the mounting cavity. The chainsaw 1-1 is arranged on one side wall of the mounting base 1-2, so that the tree branch fixing component and the chainsaw 1-1 are misaligned to prevent the chainsaw 1-1 from interfering with the tree branch fixing component during operation.
[0029] The branch fixing component includes a swing rod 1-3, a transmission component, and a fixing connecting rope 1-4. The swing rod 1-3 is swingably mounted on the mounting base 1-2 via the transmission component. The transmission component is connected to the pruning drive mechanism 3 via the fixing connecting rope 1-4 so that the pruning drive mechanism 3 can drive the transmission component to work.
[0030] The transmission components include a first gear 1-5, a second gear 1-6, and a transmission shaft 1-7. The swing arm 1-3 is fixed on the first gear 1-5. The first gear 1-5 is rotatably connected to the mounting base 1-2 via a rotating shaft. The second gear 1-6 is rotatably mounted on the mounting base 1-2 via the transmission shaft 1-7. The fixed connecting rope 1-4 is connected to the transmission shaft 1-7 and is wrapped around the outside of the transmission shaft 1-7.
[0031] In a preferred embodiment, a torsion spring connects the first gear 1-5 to the mounting base 1-2, so that the swing arm 1-3 is normally in an upward position. During the up-and-down movement of the pruning mechanism 1, the swing arm 1-3 interferes with the tree branch. The chainsaw 1-1 is positioned perpendicular to the up-and-down direction of the pruning mechanism 1. When the chainsaw interferes with the tree branch, the chainsaw 1-1 is driven to cut off the interfering branch, thereby facilitating the up-and-down movement of the pruning mechanism 1.
[0032] The end of the fixed connecting rope 1-4 is fixed to the drive shaft 1-7, and part of the fixed connecting rope 1-4 is wound around the drive shaft 1-7. By pulling the fixed connecting rope 4, the drive shaft 1-7 is driven to rotate, so that the second gear 1-6 rotates with the drive shaft 1-7, which drives the swing rod 1-3 on the first gear 1-5 to swing. By pulling the fixed connecting rope 1-4, the chainsaw 1-1 is driven to move upward, which facilitates the trimming of the branches to be cut.
[0033] By driving the chainsaw upwards to prune branches, it is possible to prevent the branches from bending due to their own weight during the pruning process, thereby preventing damage to the device from bent branches during the pruning process.
[0034] Mounting base 1-2 is slidably mounted on lifting rod 2 via slide rail 1-8. Mounting base 1-2 is provided with lifting connecting rope 1-9, which is connected to pruning drive mechanism 3. The height of pruning mechanism 1 is controlled by pulling connecting rope 1-9.
[0035] The top of the lifting rod 2 is fixed with a pulley 4 and a guide assembly 5. The guide assembly 5 is arranged on one side of the pruning mechanism 1. The lifting connecting rope 1-9 and the fixed connecting rope 1-4 are guided to the pulley 4 through the guide assembly 5.
[0036] The guide assembly 5 includes two guide posts 5-1 and a guide block 5-2. The guide block 5-2 is fixedly connected to the lifting rod 2 through the two guide posts 5-1. A roller is sleeved on the outer side of the guide post 5-1. The guide block 5-2 is provided with a guide groove 5-3. The fixed connecting rope 1-4 passes through the gap between the two guide posts 5-1 and is wound around the pulley 4. The other end of the fixed connecting rope 1-4 is connected to the pruning roller 3-3. The lifting connecting rope 1-9 is wound around the pulley 4 through the guide groove 5-3. The other end of the lifting connecting rope 1-9 is connected to the lifting roller 3-2.
[0037] The pulley 4 includes a guide wheel 4-1 and a rope sleeve 4-2. The guide wheel 4-1 has an annular groove 4-3 on its side wall. The rope sleeve 4-2 is rotatably mounted on the outside of the annular groove 4-3. The guide wheel 4-1 and the rope sleeve 4-2 can rotate relative to each other. When the lifting rod 2 moves upward, the guide wheel 4-1 can rotate relative to the tree branch when it interferes with it, which facilitates the movement of the lifting rod 2. At the same time, it can prevent the lifting connecting rope 1-9 and the fixed connecting rope 1-4 from moving when the guide wheel 4-1 rotates.
[0038] The pruning drive mechanism 3 includes a ratchet 3-1, a lifting roller 3-2, and a pruning roller 3-3. The ratchet 3-1 is rotatably mounted on the lifting rod 2 via a rotating shaft. The lifting rod 2 is provided with a ratchet 3-5, which abuts against the ratchet 3-1, causing the ratchet 3-1 to rotate in one direction. The lifting roller 3-2 is fixedly mounted on the ratchet 3-1, and the pruning roller 3-3 is rotatably mounted on the lifting roller 3-2.
[0039] The lifting roller 3-2 rotates to drive the pruning mechanism 1 to rise and fall. When the pruning mechanism 1 moves to the required height, the ratchet 3-1 is locked by the ratchet 3-5, thereby locking the pruning mechanism 1 at a fixed height. Then, the pruning roller 3-3 is rotated to drive the swing rod 1-3 to swing, so that the swing rod 1-3 is positioned above the branch to be pruned, making it convenient for the chainsaw 1-1 to prune the branch.
[0040] The pruning drive mechanism 3 also includes a rotating handle 3-4, which is slidably connected to the lifting roller 3-2 and the pruning roller 3-3. By driving the rotating handle 3-4 to move, the rotating handle 3-4 is connected to the lifting roller 3-2 or the pruning roller 3-3. By rotating the handle 3-4, the lifting connecting rope 1-9 and the fixed connecting rope 1-4 are driven to work, so that the pruning drive mechanism 3 drives the pruning mechanism 1 to lift or prune the branches.
[0041] The lifting roller 3-2 has a first idle hole 3-6, a first spline hole 3-7, and a first pivot hole 3-8 connected in sequence. These holes are coaxially arranged with the lifting roller 3-2. The pruning roller 3-3 has a second pivot hole 3-9, a second spline hole 3-10, and a second idle hole 3-11 connected in sequence. These holes are connected to the pruning roller 3-3. The first pivot hole 3-8 and the second pivot hole 3-9 are rotatably connected by a pivot sleeve 3-14, allowing the lifting roller 3-2 and the pruning roller 3-3 to rotate relative to each other. Handle 3-4 is provided with a first spline 3-12 and a second spline 3-13. When the handle 3-4 is rotated outward, the first spline 3-12 is connected to the first spline hole 3-7, while the second spline 3-13 is located in the second free-spinning hole 3-11. At this time, the handle 3-4 is connected to the lifting roller 3-2 to drive the lifting roller 3-2 to rotate. When the handle 3-4 is rotated inward, the first spline 3-12 is located in the first free-spinning hole 3-6, while the second spline 3-13 is located in the second spline hole 3-10. At this time, the handle 3-4 is connected to the pruning roller 3-3 to drive the pruning roller 3-3 to rotate, thereby realizing the switching between the functions of lifting and fixing branches of the pruning mechanism 1.
