Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pruning, in particular to a forest tending and pruning device. Background Art
[0002] Forest tending refers to the various measures taken during the forest cultivation process from afforestation to maturity to ensure the survival of young forests, promote tree growth, improve forest composition and quality, and increase forest productivity. In forest tending work, pruning equipment is needed to trim the trees, which is more conducive to the growth of the trees and can also ensure the overall neatness of the trees.
[0003] The existing pruning device mainly consists of a motor, a transmission system and a shearing knife. When pruning, the motor is started by the controller to provide power for the pruning device. The power of the motor is transmitted to the shearing knife through the transmission system. At the same time, the reduction device reduces the speed and increases the torque so that the shearing knife can generate sufficient shearing force. The operator aims the shearing knife at the branch to be pruned and presses the switch or button on the controller to start the shearing knife to work under the action of the shearing force, and the branch is cut off.
[0004] The existing pruning devices have relatively single pruning tools and lack adaptability to pruning branches of different diameters. As a result, different tools need to be frequently replaced during the pruning process to adapt to the pruning needs of branches of different thicknesses. This operation not only increases the workload, but also greatly reduces the efficiency and effect of pruning. In addition, the existing pruning devices are not convenient for pruning higher branches. Therefore, a forest tending pruning device is proposed to address the above problems. Utility Model Content
[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the present invention proposes a forest tending and pruning device.
[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a forest tending and pruning device described in the present invention includes a fixed rod, a handle is fixedly connected to the lower end of the fixed rod, a lifting sleeve is sleeved on the fixed rod, a top of the lifting sleeve is fixedly connected to a housing, a first motor is installed on the outer wall of the housing, a rotating disk is installed on the output end of the first motor, and the rotating disk is arranged in the housing, an eccentric rod is fixed on the rotating disk, a swing rod is sleeved on the eccentric rod, a lifting rod is hinged on the other end of the swing rod, and the lifting rod is arranged in a limiting hole, a limiting hole is provided on the top side of the housing, and a serrated knife is equipped on the top of the lifting rod. When pruning thicker branches, the serrated knife is first aligned with the thick branch to be pruned, and then the first motor is operated to rotate the rotating disk, forcing the eccentric rod to drive the swing rod to swing back and forth. With the cooperation of the limiting hole, the swing rod drives the lifting rod to move up and down reciprocatingly, thereby driving the serrated knife to move up and down reciprocatingly, thereby being able to saw off the thicker branches.
[0007] Preferably, a fixed block is installed on the handle, and a second motor is installed on the bottom side of the fixed block. The output end of the second motor is connected to a threaded rod, and a sliding sleeve is provided on the threaded rod, and the sliding sleeve is fixed to the lifting sleeve. When pruning high branches, the second motor is operated to rotate the threaded rod, forcing the sliding sleeve to drive the lifting sleeve upward along the threaded rod until the pruning mechanism moves to a suitable height. The second motor stops operating, so that high branches can be pruned. By setting a height adjustment mechanism, it is convenient to prune higher branches.
[0008] Preferably, a first pruning knife is installed on one side wall of the shell, and a second pruning knife is hinged on the first pruning knife, a first connecting block is installed on the first pruning knife, and a second connecting block is installed on the second pruning knife, a spring is fixed between the first connecting block and the second connecting block, and one end of the second pruning knife is provided with a pull rope, and the bottom end of the pull rope is equipped with a pull ring. When pruning thinner branches, the first pruning knife and the second pruning knife are first moved to both sides of the thin branches to be pruned, even if the thin branches to be pruned are located between the first pruning knife and the second pruning knife, the pull rope is then pulled through the pull ring, thereby driving the second pruning knife to move. With the cooperation of the first pruning knife, the thinner branches can be cut off, so that different pruning methods can be adopted according to the thickness of the branches to meet the pruning needs of branches of different thicknesses, thereby greatly improving the pruning efficiency and effect.
[0009] Preferably, a first fixing ear is installed on the shell, a second fixing ear is installed on the lifting sleeve, and the pull rope passes through the first fixing ear and the second fixing ear. When using the device, the pull rope can be limited by setting the first fixing ear and the second fixing ear.
[0010] The utility model is beneficial in that:
[0011] The scissor blade is then pulled back and forth to cut the branches, and the scissor blade is then pulled back and forth to cut the branches.
[0012] 2. When pruning high branches, the utility model operates the second motor to rotate the threaded rod, forcing the sliding sleeve to drive the lifting sleeve upward along the threaded rod until the pruning mechanism moves to a suitable height. The second motor stops operating, thereby enabling pruning of high branches. By setting a height adjustment mechanism, it is convenient to prune higher branches. BRIEF DESCRIPTION OF THE DRAWINGS

Under the cooperation of the limit hole 13, the swing rod 12 drives the lifting rod 14 to move up and down reciprocatingly, thereby driving the serrated knife 15 to move up and down reciprocatingly, so that the thicker branches can be sawed off;

[0024] Working principle: Due to the fact that the existing pruning devices have relatively single pruning tools and lack the adaptability to pruning branches of different diameters, different tools need to be frequently replaced during the pruning process to adapt to the pruning needs of branches of different thicknesses. This operation not only increases the workload, but also greatly reduces the efficiency and effect of pruning. In addition, the existing pruning devices are not convenient for pruning higher branches. Therefore, a forest tending pruning device is proposed to address the above problems. When pruning thicker branches, the serrated knife 15 is first aligned with the thick branches that need to be pruned, and then the first motor 9 is operated to rotate the rotating disk 10, forcing the eccentric rod 11 to drive the swing rod 12 to swing back and forth, and with the cooperation of the limit hole 13, the eccentric rod 11 drives the swing rod 12 to swing back and forth. The swing arm 12 drives the lifting rod 14 to move up and down reciprocatingly, thereby driving the serrated knife 15 to move up and down reciprocatingly, so that thicker branches can be sawed off; when pruning thinner branches, the first pruning knife 16 and the second pruning knife 17 are first moved to the two sides of the thin branches to be pruned. Even if the thin branches to be pruned are located between the first pruning knife 16 and the second pruning knife 17, the pull rope 21 is then pulled through the pull ring 22, thereby driving the second pruning knife 17 to move. At this time, the spring 20 is stretched, and with the cooperation of the first pruning knife 16, the thinner branches can be cut off, so that different pruning methods can be adopted according to the thickness of the branches to meet the pruning needs of branches of different thicknesses, thereby greatly improving the efficiency and effect of pruning;
[0025] When pruning high branches, the second motor 6 is operated to rotate the threaded rod 7, forcing the sliding sleeve 8 to drive the lifting sleeve 3 upward along the threaded rod 7 until the pruning mechanism moves to a suitable height. The second motor 6 stops operating, so that high branches can be pruned. By setting a height adjustment mechanism, it is convenient to prune higher branches.
