Description

Technical Field

[0001] This invention relates to the field of rapid tree pruning technology, specifically to a rapid pruning device for forestry trees. Background Technology

[0002] Forestry tree pruning is a technique that involves cutting or shortening branches to adjust the shape and structure of trees. It is primarily used to enhance the economic value of timber, improve landscape effects, and reduce fire risks. Enhancing landscape value involves improving the aesthetic appeal of the tree shape, coordinating the proportion of the tree with surrounding buildings and landscapes, and strengthening visual appeal. It also promotes balanced growth by adjusting branch distribution, improving ventilation and light penetration, reducing the occurrence of pests and diseases, balancing nutrient distribution, and enhancing the overall growth of the tree. Finally, it provides safety protection by removing dead, diseased, and insect-infested branches, thus reducing the risk of fire. Forestry trees are usually pruned by workers who use pruning shears or hand saws to trim the branches and leaves. However, pruning shears and hand saws are not very efficient. A large number of workers are needed to operate the pruning shears together, resulting in low efficiency and uneven branches and leaves that affect the appearance. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid pruning device for forest trees to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a rapid pruning device for forestry trees, including a vehicle platform, a universal wheel fixedly connected to the bottom of the vehicle platform, a cross push rod fixedly connected to the top of the vehicle platform, a curved plate fixedly connected to the top of the vehicle platform, and a pruning component provided at the end of the curved plate away from the vehicle platform. The trimming component includes an electric actuator, the top of which is fixedly connected to the surface of a bending plate. A bracket is fixedly connected to the bottom of the electric actuator, and a fixed plate is rotatably connected to the bottom of the bracket. A drive device is fixedly connected to the bottom of the inner wall of the bracket, and a rotating rod is fixedly connected to the output end of the drive device. The bottom of the rotating rod is fixedly connected to the top of the fixed plate. A threaded rod is rotatably connected to the inner wall of the fixed plate, and an adjusting rod is fixedly connected to the surface of the threaded rod. A moving block is threadedly connected to the surface of the threaded rod, and a plumb line is fixedly connected to the bottom of the moving block. A trimming frame is sleeved at the bottom of the plumb line, and a trimming device is installed inside the trimming frame. An adjusting component is provided on the surface of the trimming frame, and a stabilizing component is provided on the surface of the fixed plate.

[0005] Furthermore, the rotating rod is located inside the bracket, the end of the fixing plate extends to the outer end of the bracket, and there are two trimming frames, which are symmetrically arranged with the fixing plate as the center.

[0006] Furthermore, the adjusting rod is located at the center of the surface of the threaded rod, the surface of the moving block is in contact with the inner wall of the fixed plate, the plumb rod is located below the fixed plate, and the trimming end of the trimming device extends to the outer end of the trimming frame.

[0007] Furthermore, the adjusting component includes a fixed ring, the inner wall of which is fixedly connected to the surface of the plumb rod, a threaded telescopic rod rotatably connected to the surface of the fixed ring, a through-hole plate sleeved at the end of the threaded telescopic rod away from the fixed ring, the end of the through-hole plate away from the threaded telescopic rod being hinged to the surface of the trimming frame, and a torsion ring fixedly connected to the surface of the threaded telescopic rod.

[0008] Furthermore, there are two threaded telescopic rods, which are symmetrically arranged with the fixed plate as the center. The ends of the two threaded telescopic rods that are far apart from each other are the telescopic ends, and the fixing ring is located on the upper surface of the plumb line.

[0009] Furthermore, the end of the through-hole plate away from the threaded telescopic rod is inclined toward the surface of the trimming frame, the bottom of the through-hole plate is located on the lower surface of the trimming frame, and the through-hole plate is located at the ends of the two trimming frames that are far apart from each other.

[0010] Furthermore, the stabilizing component includes a positioning frame, the surface of which is fixedly connected to the surface of a fixed plate, a center plate fixedly connected to the inner wall of the positioning frame, a spring rod fixedly connected to the surface of the center plate, a slide plate fixedly connected to the end of the spring rod away from the center plate, a telescopic plate fixedly connected to the bottom of the slide plate, and a shaft fixedly connected to the surface of the trimming frame.

[0011] Furthermore, the number of telescopic plates is set to four, and the four telescopic plates are set to two groups, with two in each group, and the two telescopic plates are symmetrically arranged with the trimming frame as the center.

[0012] Furthermore, the bottom of the telescopic plate is sleeved on the surface of the shaft, the shaft is located at the center of the surface of the trimming frame, the center plate is located at the inner center of the positioning frame, and the surface of the sliding plate is slidably connected to the inner wall of the positioning frame.

[0013] The present invention has the following beneficial effects: This invention features a cross-shaped push rod at the top of the vehicle platform, allowing workers to control the platform's movement. As the platform moves, a curved plate pushes the pruning components, which then move horizontally across the tree's surface to prune the branches and leaves at both ends. The platform limits the position of the pruning components, preventing uneven pruning. When pruning is needed, the worker twists an adjusting rod to rotate a threaded rod inside a fixed plate. The moving blocks and threaded rod are threadedly connected. Rotation of the threaded rod pushes two moving blocks closer or further apart, adjusting the position of the pruning devices. This ensures the distance between the two pruning devices aligns with the sides of the tree, allowing simultaneous pruning of both sides and improving pruning efficiency. The electric push rod adjusts the height of the fixed plate during operation, enabling more comprehensive pruning.

[0014] When the angle of the pruning frame needs to be adjusted, the worker rotates the threaded telescopic rod on the surface of the fixed ring by twisting the torsion ring. The threaded telescopic rod extends or retracts according to the direction of rotation. When the threaded telescopic rod extends to pull the pruning frame around the vertical rod through the through-hole plate, the bottom of the two pruning frames will move away from each other. After the pruning frame is adjusted to the corresponding angle, the pruning device will also adjust its angle accordingly. After the fixed plate is moved above the trees, the distance between the pruning device and the trees is adjusted by the electric actuator. The drive device is started to drive the rotating rod to rotate. When the rotating rod rotates, it drives the pruning device to rotate through the fixed plate. At this time, the pruning device can perform spherical pruning of the trees, improving the convenience of tree pruning and reducing the labor intensity of workers. When the two threaded telescopic rods are adjusted to move closer to each other, the through-hole plate pushes the bottom of the two pruning frames to move closer to each other along with the movement of the threaded telescopic rods. At this time, the pruning device can perform spherical pruning of the lower end of the trees, improving practicality.

[0015] When the distance or angle of the trimming frame is adjusted, the telescopic plate is moved by the shaft. When the telescopic plate moves, the sliding plate squeezes the elastic rod. At this time, the trimming frame squeezes the through-hole plate under the pressure of the elastic rod. The trimming frame remains stable under the action of the through-hole plate and the elastic rod, thus improving the stability of the trimming frame in supporting the trimming device.

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

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9As shown, the present invention is a rapid pruning device for forest trees, including a vehicle plate 1, a universal wheel 2 fixedly connected to the bottom of the vehicle plate 1, a cross push rod 3 fixedly connected to the top of the vehicle plate 1, a curved plate 4 fixedly connected to the top of the vehicle plate 1, and a pruning component 5 provided at the end of the curved plate 4 away from the vehicle plate 1. The trimming component 5 includes an electric push rod 10. The top of the electric push rod 10 is fixedly connected to the surface of the bending plate 4. A bracket 11 is fixedly connected to the bottom of the electric push rod 10. A fixed plate 13 is rotatably connected to the bottom of the bracket 11. A drive device 12 is fixedly connected to the bottom of the inner wall of the bracket 11. A rotating rod 20 is fixedly connected to the output end of the drive device 12. The bottom of the rotating rod 20 is fixedly connected to the top of the fixed plate 13. A threaded rod 18 is rotatably connected to the inner wall of the fixed plate 13. An adjusting rod 17 is fixedly connected to the surface of the threaded rod 18. A moving block 16 is threadedly connected to the surface of the threaded rod 18. A vertical rod 19 is fixedly connected to the bottom of the moving block 16. A trimming frame 14 is sleeved on the bottom of the vertical rod 19. The position of the trimming component 5 is limited by the vehicle plate 1. To avoid unevenness after tree pruning, when pruning is required, the worker twists the adjusting rod 17 to drive the threaded rod 18 to rotate inside the fixed plate 13. The moving block 16 is threadedly connected to the threaded rod 18. When the threaded rod 18 rotates, it pushes the two moving blocks 16 to move closer or further apart. When the moving blocks 16 move, they adjust the position of the pruning device 15, so that the distance between the two pruning devices 15 corresponds to the two sides of the tree, which makes it convenient for the pruning device to prune both sides of the tree at the same time. The pruning device 15 is installed inside the pruning frame 14. The surface of the pruning frame 14 is provided with adjusting components 6, and the surface of the fixed plate 13 is provided with stabilizing components 7.

[0022] The rotating rod 20 is located inside the bracket 11, the end of the fixing plate 13 extends to the outer end of the bracket 11, and there are two trimming frames 14, which are symmetrically arranged with the fixing plate 13 as the center.

[0023] The adjusting rod 17 is located at the center of the surface of the threaded rod 18, the surface of the moving block 16 is in contact with the inner wall of the fixed plate 13, the vertical rod 19 is located below the fixed plate 13, and the trimming end of the trimming device 15 extends to the outer end of the trimming frame 14.

[0024] Adjusting component 6 includes a fixed ring 30, the inner wall of which is fixedly connected to the surface of the vertical rod 19. A threaded telescopic rod 31 is rotatably connected to the surface of the fixed ring 30. A through-hole plate 32 is sleeved on the end of the threaded telescopic rod 31 away from the fixed ring 30. The end of the through-hole plate 32 away from the threaded telescopic rod 31 is hinged to the surface of the trimming frame 14. A torsion ring 33 is fixedly connected to the surface of the threaded telescopic rod 31. When the angle of the trimming frame 14 needs to be adjusted, the worker twists the threaded telescopic rod 31 through the torsion ring 33 to rotate it on the surface of the fixed ring 30. The threaded telescopic rod 31 extends or retracts depending on the direction of rotation. In operation, the threaded telescopic rod 31 extends through the through-hole plate 32 to pull the pruning frame 14 to rotate around the vertical rod 19. At this time, the bottoms of the two pruning frames 14 will move away from each other. After the pruning frame 14 is adjusted to the corresponding angle, the pruning device 15 will also adjust its angle accordingly. After the fixing plate 13 is moved above the trees, the distance between the pruning device 15 and the trees is adjusted by the electric push rod 10. The drive device 12 is started to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it drives the pruning device 15 to rotate through the fixing plate 13. At this time, the pruning device 15 can perform spherical pruning on the trees.

[0025] There are two threaded telescopic rods 31, which are symmetrically arranged with the fixing plate 13 as the center. The ends of the two threaded telescopic rods 31 that are far apart from each other are the telescopic ends, and the fixing ring 30 is located on the upper surface of the vertical rod 19.

[0026] The end of the through-hole plate 32 away from the threaded telescopic rod 31 is inclined toward the surface of the trimming frame 14, the bottom of the through-hole plate 32 is located on the lower surface of the trimming frame 14, and the through-hole plate 32 is located at the ends of the two trimming frames 14 that are far apart from each other.

[0027] The stabilizing component 7 includes a positioning frame 40, the surface of which is fixedly connected to the surface of the fixing plate 13. A center plate 43 is fixedly connected to the inner wall of the positioning frame 40. A spring rod 45 is fixedly connected to the surface of the center plate 43. A slide plate 44 is fixedly connected to the end of the spring rod 45 away from the center plate 43. A telescopic plate 41 is fixedly connected to the bottom of the slide plate 44. A shaft 42 is fixedly connected to the surface of the trimming frame 14. When the distance or angle of the trimming frame 14 is adjusted, the telescopic plate 41 is moved by the shaft 42. When the telescopic plate 41 moves, it squeezes the spring rod 45 through the slide plate 44. At this time, the trimming frame 14 squeezes the through-hole plate 32 under the squeezing of the spring rod 45. At this time, the trimming frame 14 remains stable under the action of the through-hole plate 32 and the spring rod 45.

[0028] There are four telescopic plates 41, which are set in two groups, and each group has two plates. The two telescopic plates 41 are symmetrically arranged with the trimming frame 14 as the center.

[0029] The bottom of the telescopic plate 41 is sleeved on the surface of the shaft 42, the shaft 42 is located at the center of the surface of the trimming frame 14, the center plate 43 is located at the inner center of the positioning frame 40, and the surface of the slide plate 44 is slidably connected to the inner wall of the positioning frame 40.

[0030] In use, a cross push rod 3 is provided on the top of the platform 1, which allows the worker to control the movement direction of the platform 1. When the platform 1 moves, the bending plate 4 pushes the pruning component 5 to move. The pruning component 5 moves horizontally on the surface of the tree through the movement of the platform 1, thereby pruning the branches and leaves at both ends of the tree. The platform 1 limits the position of the pruning component 5 to avoid unevenness after the tree is pruned. When the trees need to be pruned, the worker twists the adjusting rod 17 to drive the threaded rod 18 to rotate inside the fixed plate 13. The moving block 16 and the threaded rod 18 are threadedly connected. When the threaded rod 18 rotates, it pushes the two moving blocks 16 to move closer or further away from each other. When the moving blocks 16 move, they adjust the position of the pruning device 15, so that the distance between the two pruning devices 15 corresponds to the two sides of the tree, which makes it convenient for the pruning device to prune both sides of the tree at the same time, improving the pruning efficiency. When the electric push rod 10 is working, it adjusts the height of the fixed plate 13 so that the pruning device 15 can prune the trees more comprehensively. When the angle of the pruning frame 14 needs to be adjusted, the worker twists the threaded telescopic rod 31 on the surface of the fixed ring 30 by twisting the twisting ring 33. The threaded telescopic rod 31 extends or retracts according to the direction of rotation. When the threaded telescopic rod 31 extends to pull the pruning frame 14 around the vertical rod 19 through the through-hole plate 32, the bottoms of the two pruning frames 14 will move away from each other. After the pruning frame 14 is adjusted to the corresponding angle, the pruning device 15 will also adjust its angle accordingly. After the fixed plate 13 is moved above the trees, the pruning device 15 is adjusted by the electric actuator 10. The distance between the device 15 and the trees is adjusted. The drive device 12 is activated to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it drives the pruning device 15 to rotate through the fixed plate 13. At this time, the pruning device 15 can perform spherical pruning on the trees, which improves the convenience of pruning the trees and reduces the labor intensity of workers. When the two threaded telescopic rods 31 are adjusted to move closer to each other, the through-hole plate 32 pushes the bottom of the two pruning frames 14 to move closer to each other as the threaded telescopic rods 31 move. At this time, the pruning device 15 can perform spherical pruning on the lower end of the trees, which improves practicality. When the distance or angle of the trimming frame 14 is adjusted, the telescopic plate 41 is moved by the shaft 42. When the telescopic plate 41 moves, the spring rod 45 is squeezed by the slide plate 44. At this time, the trimming frame 14 will squeeze the through-hole plate 32 under the pressure of the spring rod 45. The trimming frame 14 remains stable under the action of the through-hole plate 32 and the spring rod 45, which improves the stability of the trimming frame 14 in supporting the trimming device 15.
