Description

Technical Field

[0001] This utility model relates to the field of chestnut planting technology, and in particular to an adjustable chestnut tree branch pruning aid. Background Technology

[0002] As an important economic forest tree, chestnut trees require careful pruning during cultivation. Pruning not only promotes healthy tree growth but also improves fruit yield and quality. Chestnut tree pruning is mainly divided into two stages: winter pruning and summer pruning. Winter pruning is typically carried out during the tree's dormancy period, primarily to reduce nutrient consumption and accumulate energy for the following year's growth. Summer pruning, on the other hand, is mainly conducted during the growing season to adjust the tree's growth vigor and maintain ventilation and light penetration within the canopy, thereby promoting fruit development and ripening.

[0003] However, during the pruning process, due to the height of some chestnut trees and the limited length of traditional pruning tools, pruning high branches becomes particularly difficult. In order to prune high branches, operators often need to climb up the tree to carry out the work, which not only increases the complexity of the operation, but more importantly, poses a great safety hazard to operators when working at height. Once they lose their footing or operate improperly, serious accidents such as falling from a height may occur.

[0004] Therefore, it is necessary to provide an adjustable chestnut branch pruning aid to solve the above-mentioned technical problems. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides an adjustable chestnut branch pruning aid, such as... Figure 1-4As shown, the adjustable chestnut branch pruning aid includes: a first cylinder 1, on which a second cylinder 2 is slidably mounted; a housing 3 welded to the second cylinder 2, on which a rotating shaft 4 is rotatably mounted; a support block 5 fixedly sleeved on the rotating shaft 4, the support block 5 being slidably connected to a groove on the housing 3; a first servo motor 7 fixedly mounted on the housing 3, the output shaft of the first servo motor 7 being fixedly connected to one end of the rotating shaft 4; a box 6 fixedly mounted on the support block 5, the box 6 being provided with a pruning mechanism for pruning chestnut branches; and an adjustment mechanism assembled on the first cylinder 1 for adjusting the pruning height.

[0023] In this embodiment, when the tool is in use, the pruning mechanism can prune the chestnut tree branches that need to be pruned. When the branch to be pruned is at a high position, the adjustment mechanism can be activated to drive the second cylinder 2 to extend outward from the first cylinder 1, so that the pruning mechanism can be raised to the required position. Then, the branch can be pruned by the pruning mechanism. When the tool is obstructed by some branches, if the pruning mechanism needs to adjust the angle to achieve the pruning work, the first servo motor 7 needs to be activated. The first servo motor 7 will drive the rotating shaft 4 to rotate, the rotating shaft 4 will drive the support block 5 to rotate, and the support block 5 will drive the housing 6 to rotate, thereby adjusting the use angle of the pruning mechanism. This makes the pruning work more convenient and has a better effect.

[0024] In a further preferred embodiment of the present invention, the trimming mechanism includes: a first blade 8 fixedly installed on the housing 6; an electric telescopic rod 9 fixedly installed on the inner wall of the housing 6, a connecting block 10 fixedly installed on the output rod of the electric telescopic rod 9, the connecting block 10 being slidably connected to a limiting groove on the housing 6; and a second blade 11 fixedly installed on the connecting block 10.

[0025] In this embodiment, the pruning mechanism is used to prune chestnut tree branches. When pruning, the electric telescopic rod 9 is activated, which will drive the connecting block 10 to slide in the limiting groove on the box 6. The connecting block 10 will drive the second blade 11 to approach the first blade 8. When the second blade 11 contacts the first blade 8, the branches can be pruned.

[0026] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a protective sleeve 12 fixedly sleeved on the first cylindrical body 1, a second servo motor 13 fixedly installed on the inner wall of the protective sleeve 12; and a screw 14 rotatably installed on the first cylindrical body 1, the screw 14 being threadedly connected to the second cylindrical body 2, and one end of the screw 14 being fixedly connected to the output shaft of the second servo motor 13.

[0027] In this embodiment, the adjustment mechanism is used to adjust the pruning height. During adjustment, the second servo motor 13 is started, which drives the screw 14 to rotate. The screw 14 drives the second cylinder 2 to slide on the first cylinder 1. The second cylinder 2 drives the housing 3 to rise and fall. The housing 3 drives the box 6 to rise and fall through the rotating shaft 4 and the support block 5. The box 6 drives the pruning mechanism to rise and fall, so that the pruning mechanism can prune the branches to be pruned at a suitable height.

[0028] In a further preferred embodiment of the present invention, a hanging rope 15 is fixedly installed on the protective sleeve 12, and the hanging rope 15 is made of nylon material.

[0029] In this embodiment, the lanyard 15 made of nylon material makes it difficult for the operator's hand to slip off when holding the protective sleeve 12.

[0030] In a further preferred embodiment of the present invention, a sliding groove is provided on the inner wall of the first cylinder 1, and a limiting block 16 is slidably installed on the inner wall of the sliding groove, and one side of the limiting block 16 is fixedly connected to the second cylinder 2.

[0031] In this embodiment, the cooperation of the slide and the limiting block 16 can ensure the stability of the second cylinder 2 moving vertically within the first cylinder 1, so as to prevent the second cylinder 2 from rotating during vertical movement.

[0032] In a further preferred embodiment of the present invention, a limiting rod 17 is fixedly installed on the inner wall of the limiting groove, and the limiting rod 17 is slidably connected to the connecting block 10.

[0033] In this embodiment, the use of the limiting rod 17 can effectively limit the connecting block 10, thereby further improving the stability of the second blade 11 during movement.

[0034] In a further preferred embodiment of the present invention, a controller is fixedly installed on the outer wall of the first cylinder 1, and both the first blade 8 and the second blade 11 are made of stainless steel.

[0035] In this embodiment, the use of a controller allows the user to easily control the tool. The first blade 8 and the second blade 11, made of stainless steel, have good corrosion resistance and durability and are not easily damaged.

[0036] In summary, compared with related technologies, this solution, through the use of an adjustment mechanism, allows personnel to easily raise and lower the pruning mechanism to a suitable height for pruning tall chestnut tree branches without climbing the tree. This effectively solves the technical problems of the difficulty in pruning high branches of chestnut trees and the high safety risks for operators performing high-altitude pruning operations. The use of the first servo motor 7 drives the rotating shaft 4 to rotate, which in turn drives the support block 5 to rotate, which in turn drives the housing 6 to rotate. This allows for adjustment of the pruning mechanism's angle, enabling it to prune the desired branches even when obstructed by branches. This facilitates the pruning work and yields good results.
