Description

Technical Field

[0001] The utility model relates to the technical field of garden maintenance equipment, in particular to a tree pruning device with a lifting mechanism. Background Technique

[0002] In modern garden construction, tall trees (such as arbors, pines or fruit trees, etc.) are one of the essential components. As the trees grow, the branches and leaves gradually become lush. In order to improve and maintain the landscape effect, it is necessary to regularly prune the branches and leaves of the trees.

[0003] Application No.: CN202223510635.5, "Tree Pruning Device". Since the circular knife is arranged at the top of the hand-held rod, the staff can complete the pruning of the branches and leaves of tall trees by holding the bottom of the hand-held rod and standing on the ground. Compared with the prior art, there is no need to build a scaffolding for climbing or use a lifting engineering vehicle. The work efficiency is high, the labor cost is low, and the staff does not need to work at height, which can effectively avoid the safety hazards existing in working at height. Due to the setting of the circular knife protective shell, before performing the tree branch and leaf pruning operation, first send the circular knife to the branch to be pruned with the hand-held rod in the closed state of the protective shell, and open each protective shell flap. When pruning the target branches and leaves, the target branches and leaves can be separated from the surrounding branches and leaves through the protective shell flaps around the circular knife, avoiding accidentally cutting off the surrounding branches and leaves when pruning the target branches and leaves. After the tree pruning operation is completed, close each protective shell flap, and the circular knife can be protected by the circular knife protective shell, which can not only prevent the circular knife from being damaged due to collision, but also prevent the circular knife from scratching people or objects around. Since the length of the hand-held rod is adjustable, the staff can flexibly adjust the length of the hand-held rod according to the height of the target branches and leaves to be pruned, so as to complete the pruning of target branches and leaves at different heights on the ground.

[0004] However, the above-mentioned tree pruning device itself does not have the function of telescopic lifting, which may make it impossible to reach when pruning the higher branches, and may be inflexible to use due to the longer pruning device when pruning the higher branches, thus causing inconvenience in the use of the tree pruning device. Content of the Utility Model

The side of the telescopic rod 12 is slidably inserted into the inner ring of the sleeve 13, and a strip-shaped limiting through hole 15 is opened on the side of the sleeve 13.

[0026] Further, start the first driving motor 17, the first driving motor 17 drives the lead screw 16 to rotate clockwise. When the lead screw 16 rotates clockwise, it drives the telescopic rod 12 to extend out of the sleeve 13, thereby increasing the length of the pruning device and making it more convenient to prune the high branches. When pruning the low branches, the first driving motor 17 drives the lead screw 16 to rotate counterclockwise. When the lead screw 16 rotates counterclockwise, it drives the telescopic rod 12 to retract into the sleeve 13, thereby shortening the overall length of the pruning device and making the pruning device more flexible to use, so as to facilitate pruning the low branches. Through the above method, the pruning device has the function of telescopic lifting, is more flexible and convenient to use, and is more conducive to pruning high and low branches.

[0027] The hole wall of the strip-shaped limiting through hole 15 is slidably connected to the outside of the slider 14, and one end of the slider 14 is fixedly connected to the side of the bottom end of the telescopic rod 12.

[0028] Further, the cooperation of the slider 14 and the strip-shaped limiting through hole 15 can prevent the telescopic rod 12 from rotating with the lead screw 16.

[0030] Further, move the moving block 31 above the branch to be pruned so that the V-shaped groove 32 is attached to the upper part of the branch. Then start the electric push rod 34, the output shaft of the electric push rod 34 retracts and drives the moving block 31 to move towards the fixing block 22, thereby making the moving block 31 push the branch towards the fixing block 22. The V-shaped groove 32 can prevent the branch from detaching from the moving block 31.

[0031] The cutting assembly 2 includes: a fixing block 22, the bottom of the fixing block 22 is fixedly connected to the top end of the telescopic rod 12, and an installation groove 21 is opened inside the fixing block 22.

The output shaft of the electric push rod 34 retracts and drives the moving block 31 to move towards the fixed block 22, thereby making the moving block 31 push the branch towards the fixed block 22. The V-shaped groove 32 can prevent the branch from detaching from the moving block 31. When the branch moves to the position of the cutting blade wheel 25, the second driving motor 24 drives the cutting blade wheel 25 to rotate, so that the cutting blade wheel 25 cuts and trims the branch.

[0035] When trimming the high branches, start the first driving motor 17. The first driving motor 17 drives the lead screw 16 to rotate clockwise. When the lead screw 16 rotates clockwise, it drives the telescopic rod 12 to extend out of the sleeve 13, thereby increasing the length of the trimming device and making it more convenient to trim the high branches; when trimming the low branches, the first driving motor 17 drives the lead screw 16 to rotate counterclockwise. When the lead screw 16 rotates counterclockwise, it drives the telescopic rod 12 to retract into the sleeve 13, thereby shortening the overall length of the trimming device and making the trimming device more flexible to use, so as to facilitate trimming the low branches; through the above method, the trimming device has the function of telescopic lifting, is more flexible and convenient to use, and is more conducive to trimming the high and low branches.
