Description

Technical Field

[0001] This invention relates to the field of walnut tree pruning technology, and more particularly to a walnut tree pruning device. Background Technology

[0002] Walnut trees, also known as Juglans regia, are deciduous trees belonging to the Juglandaceae family. They are one of my country's important economic forest tree species. Their fruit, walnuts, is rich in unsaturated fatty acids, protein, and various trace elements, possessing high nutritional value and health benefits. The wood is tough and fine-grained, making it a high-quality timber. Walnut trees have well-developed root systems, are tall, and can reach heights of over 10 meters during their peak fruiting period. They have broad crowns and vigorous branch growth. In the cultivation and management of walnut trees, pruning is an essential agronomic measure. Scientific pruning of walnut trees is mainly based on the following reasons: First, it adjusts the tree structure and improves ventilation and light penetration. Under natural growth conditions, walnut trees have dense and disordered branches, easily forming "inner canopy closure," which weakens photosynthesis in the inner leaves, affecting flower bud differentiation and fruit quality. Pruning can remove overly dense, crossing, and overlapping branches, allowing for better ventilation and light penetration within the canopy. Secondly, cultivate a reasonable tree shape to balance vegetative and reproductive growth. Young walnut trees have vigorous growth; without proper shaping, problems such as excessively tall trunks and uneven distribution of main branches can easily occur, hindering later fruiting. Pruning can be used to cultivate high-yielding tree shapes such as open-center or central-center systems, promoting nutrient allocation to fruiting branches and preventing excessive nutrient consumption by vigorous shoots. Thirdly, remove diseased, pest-infested, and dead branches to reduce the base population of pests and diseases. Walnut trees are susceptible to diseases such as walnut leafminer moth, rot, and dieback. Timely pruning and centralized disposal of diseased and pest-infested branches can effectively cut off the source of infection and reduce the use of chemical pesticides. Therefore, pruning directly affects the yield, quality, and lifespan of walnut trees and is an indispensable technical aspect of walnut orchard management.

[0003] In existing technology, pruning of walnut trees is usually done by manual climbing. This requires people to carry ladders and use shears to cut walnut branches at different locations after climbing up. When it is necessary to change the location to prune branches at different locations, the ladder needs to be carried, the position adjusted, and then the person has to climb up again. This kind of work not only wastes a lot of manpower and is very inefficient, but also has low safety during pruning, with a risk of accidental falls, and cannot provide effective protection for personal safety. Summary of the Invention

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1: A walnut tree pruning device, such as Figure 1-8As shown, the pruning assembly includes a base 1. A multi-section lifting rod 11 is mounted on the top of the base 1. A rotary motor 19 is mounted on the top of the multi-section lifting rod 11. A rotary shaft 20 is connected to the output end of the rotary motor 19. A connecting seat 21 is mounted on the top of the rotary shaft 20. A control motor 22 is mounted on one side of the connecting seat 21. A connecting shaft 30 is connected to the output end of the control motor 22. One end of the connecting shaft 30 rotatably passes through the connecting seat 21. An adjusting frame 23 is mounted on the connecting shaft 30. A rotating platform 24 is mounted on the top of the adjusting frame 23. A fixed seat 25 is fixedly installed on the rotating end of the top of the rotating platform 24. A motor compartment 26 is mounted on one side of the fixed seat 25. A transmission shaft 32 is connected to the output end of the motor compartment 26. One end of the transmission shaft 32 rotatably passes through the fixed seat 25. A pruning saw blade 27 is mounted on the transmission shaft 32. A disinfection component for disinfection is mounted on one side of the fixed seat 25. A protective component for protection is mounted on one side of the multi-section lifting rod 11. A moving component for adjusting the position is mounted on one side of the base 1. In use, the base 1 can be easily moved by the movable component, and the position of the multi-section lifting rod 11 can be quickly adjusted according to the required pruning position. Activating the multi-section lifting rod 11 controls the height adjustment of the pruning saw blade 27. The multi-section lifting mechanism allows the pruning saw blade 27 to be raised to a higher height, thus adapting to walnut trees of different heights and facilitating the pruning of excessively tall walnut trees. Activating the motor in the motor compartment 26 controls the rotation of the drive shaft 32 and the pruning saw blade 27. The high-speed rotation of the pruning saw blade 27 allows for rapid cutting and pruning of the walnut tree branches, which is more efficient than manual pruning with shears. Activating the rotary motor 19 controls the rotation of the rotary shaft 20, which synchronously controls the rotation of the pruning saw blade 27, thereby adjusting the pruning direction of the pruning saw blade 27. Activating the control motor 22 controls the rotation of the connecting shaft 30. When the shaft rotates, the adjusting frame 23 can be driven to rotate synchronously. The tilt angle of the pruning saw blade 27 can be adjusted by rotating the adjusting frame 23. The rotation of the pruning saw blade 27 can be controlled by starting the rotating platform 24, thereby adjusting the pruning angle. The pruning saw blade 27 can be adjusted in multiple directions and angles by cooperating with the rotating shaft 20, the adjusting frame 23 and the rotating platform 24. With the height adjustment of the multi-section lifting rod 11, branches at different positions and heights of the walnut tree can be pruned, which can effectively improve the pruning efficiency and avoid the problem of limited position and angle of the pruning saw blade 27 during pruning. There is no need to manually climb to a high place for pruning, which solves the problem of low efficiency and poor safety of carrying ladders to climb high for pruning. There is no need for manual climbing, which provides effective protection for personal safety and avoids the risk of accidental falls during pruning. It can effectively improve the efficiency and safety of pruning. The disinfection assembly includes a disinfection rack 28, which is installed on one side of a fixed base 25. The inner walls of both sides of the disinfection rack 28 are provided with inclined surfaces, and several sets of spray holes are provided on the inclined surfaces. The spray holes are oriented towards the trimming saw blade 27. A liquid storage tank 31 is provided on one side of the fixed base 25. A delivery pipe is connected to one side of the liquid storage tank 31, and the other end of the delivery pipe is connected to the disinfection rack 28. A liquid filling port is provided on the top of the liquid storage tank 31, and a protective cover is detachably provided on one end of the liquid filling port. During use, the protective cover can be removed and alcohol or prepared disinfectant can be added to the storage tank 31 through the filling port. On-site operators can freely choose the type of disinfectant as needed. After adding, the protective cover can be reinstalled to seal the tank and prevent the disinfectant from spilling out of the storage tank 31 when the fixed seat 25 is adjusted in angle and direction. The storage tank 31 is equipped with a delivery pump. The delivery pump can deliver the disinfectant to the delivery pipe. After the disinfectant is fed into the disinfection rack 28 through the delivery pipe, it can be sprayed out from several sets of spray holes on both sides. The spray holes on the inclined surface of the disinfection rack 28 are directly facing the pruning saw blade 27. The sprayed disinfectant can fully spray the pruning saw blade 27. The rotation of the pruning saw blade 27 can make it fully contact the disinfectant for disinfection. After disinfection, the pruning saw blade 27 can be used to prune walnut trees, avoiding cross-infection of rot and branch dieback at the cut after pruning, and preventing disease after pruning. The protective assembly includes a mounting bracket 12, which is mounted on one end of a multi-section lifting rod 11. A mounting base 13 is provided on one side of the mounting bracket 12, and an adjusting motor 15 is provided on one side of the mounting base 13. A fixed shaft 29 is connected to the output end of the adjusting motor 15. One end of the fixed shaft 29 is rotatably installed through the mounting base 13, and a protective baffle 14 is provided on the fixed shaft 29. The protective baffle 14 is made of tempered glass. When in use, the protective baffle 14 is made of transparent high-strength tempered glass, which has good light transmission and protection. During operation and pruning, the pruning area can be observed through the transparent protective baffle 14. The fixed shaft 29 and the protective baffle 14 can be controlled to rotate by adjusting the motor 15. When protection is not needed, the protective baffle 14 can be rotated and retracted to reduce space occupation. When protection is needed, the protective baffle 14 can be rotated and unfolded to effectively shield and protect the operators under the tree during pruning. This can avoid the problem of branches falling and injuring the operators during pruning, and further improve safety. At the same time, it can improve safety without affecting normal observation. The moving component includes omnidirectional casters 2, and several sets of omnidirectional casters 2 are symmetrically installed on the bottom of the base 1. A fixed bracket 16 is provided on the top of the base 1, and a handle 17 is installed through the fixed bracket 16. When in use, the universal caster wheel 2 has several sets of anti-slip grooves arranged in a circle on the caster wheel, which can improve the friction with the ground and prevent slippage during movement. When it is necessary to adjust the pruning position or move to the position of other walnut trees, you can hold the handle 17 and push the device. By pushing, the universal caster wheel 2 can be rotated in contact with the ground, so that the displacement can be completed efficiently and conveniently without the need for carrying. This makes position adjustment more effortless. At the same time, holding the handle 17 makes it easy to exert force and can accurately control the distance and direction of displacement. In order to provide energy to maintain operation, such as Figure 1 , 6 As shown, a power compartment 3 is provided on the top of the base 1, a cover plate 4 is detachably provided on one side of the power compartment 3, and a solar charging panel 5 is provided on the top of the power compartment 3. In use, the power compartment 3 is connected to various components via wires. The cover plate 4 can be removed to install the battery pack inside the power compartment 3. After installation, the cover plate 4 can be replaced to seal the power compartment 3, thus effectively protecting the internal battery pack and preventing unnecessary damage. The installed battery pack can provide energy to ensure the normal operation of various components. When the power is low, the cover plate 4 can be removed to replace the battery pack, which can effectively improve the energy replenishment efficiency. The solar charging panel 5 can receive sunlight and convert it into energy for use, which can improve the running range. To prevent slippage during movement, such as Figure 7 As shown, the grip 17 is provided with an anti-slip sleeve 18. The anti-slip sleeve 18 is made of silicone material, and the surface of the anti-slip sleeve 18 has several sets of anti-slip textures arranged in a circle. When using the grip 17 to control movement, both hands can hold the two sets of anti-slip sleeves 18 respectively. The anti-slip sleeves 18 made of silicone material, together with the anti-slip texture, can increase the friction with the hand, thereby preventing the hand from slipping when controlling movement. In order to grind the trimmer saw blade 27, such as Figure 5 As shown, a speed-regulating motor 33 is provided on one side of the power supply compartment 3, and a mounting shaft 34 is connected to the output end of the speed-regulating motor 33. A grinding wheel 35 is detachably mounted on the mounting shaft 34. During use, the speed-regulating motor 33 can be used to control the rotation of the mounting shaft 34 and the grinding wheel 35. After a long period of pruning, the pruning saw blade 27 can be removed. After removal, the pruning saw blade 27 is controlled to contact the rotating grinding wheel 35. The grinding wheel 35 contacts the pruning saw blade 27 and rotates to grind it, which can maintain the sharpness of the pruning saw blade 27, avoid damage to the branches of the walnut tree during cutting and pruning, and also improve the efficiency of pruning. To support the multi-section lifting boom 11, such as Figure 5 ,6 As shown, a reinforcing frame 10 is provided at one end of the multi-section lifting rod 11, and the bottom end of the reinforcing frame 10 is fixed to the base 1; When in use, the reinforcing frame 10 set on the top of the base 1 can effectively support the multi-section lifting rod 11, preventing it from shifting and tipping over after being raised, thus increasing safety hazards and further improving safety during pruning. To prevent tipping, such as Figure 1 , 8 As shown, connecting frames 6 are symmetrically arranged on both sides of the base 1. Electric push rods 7 are arranged at the bottom of the connecting frames 6. Support feet 8 are fixedly installed at the telescopic end of the bottom of the electric push rods 7. Several sets of positioning cones 36 are arranged in a circular pattern at the bottom of the support feet 8. The positioning cones 36 are conical in shape. When in use, the conical positioning cone 36 is positioned with its tip pointing downwards. When moving to the desired position for trimming, the electric actuator 7 can be activated to control the support pads 8 to fall and contact the ground. The two sets of support pads 8 falling and contacting the ground can provide stable support for the device, preventing the device from shifting its center of gravity during trimming and causing it to tip over. When the support pads 8 fall, the conical positioning cone 36 at their bottom will insert into the ground. The insertion of the positioning cone 36 into the ground can reinforce the support pads 8 and prevent unnecessary displacement of the support pads 8 from affecting the stability of the support.

[0024] Example 2: To store tools and spare pruning saw blades 27, refer to Figure 1 , 5 A walnut tree pruning device, the present embodiment is improved compared with embodiment 1 as follows: a storage cabinet 9 is provided on the top of the base 1, and a cabinet door is provided on one side of the storage cabinet 9; When in use, the cabinet door can be rotated to open and close the storage cabinet 9. The space inside the storage cabinet 9 can be used to store commonly used tools and spare trimming saw blades 27, which can be quickly retrieved when needed, making the operation more convenient.
