Description

Technical Field

[0001] This utility model relates to the field of forestry branch pruning technology, and in particular to a forestry branch pruning device. Background Technology

[0002] Under natural growing conditions, trees in forestry tend to have uneven branch growth, which can easily lead to overly dense, overlapping, crossing, weak, diseased, or insect-infested branches. These branches are not only unsightly but also affect the growth and development of the forest. Therefore, forestry workers need to prune these branches to ensure healthy tree growth, improve forestry production value, and make the forest more neat and aesthetically pleasing.

[0003] A search revealed a forestry branch pruning device with publication number CN218184158U, comprising: a body including a pruning rod, with an electric saw movably connected to the surface of the pruning rod; a telescopic mechanism including a connecting rod movably connected to the inner surface of the pruning rod; and a disassembly mechanism including a second fixing block fixedly connected to the outer surface of the pruning rod, with a screw movably connected to the surface of the second fixing block. This invention, by allowing the connecting rod and auxiliary rod to telescopically connect and fix within the pruning rod, enables the electric saw to prune branches at greater distances with the help of the pruning rod, avoiding the limitations of pruning devices that cannot prune branches too far away. The mutual restraint and fixation between the screw, movable ring, first movable column, and second movable column facilitates the removal and installation of the electric saw on the pruning rod, allowing for timely replacement and reuse of the electric saw after damage.

[0004] When pruning branches high in the air, the device in the disclosed patent requires workers to hold up a pruning pole with one hand and use an electric saw to prune the branches. Since there are many branches to be pruned, it is easy for workers to experience arm pain when holding the pruning pole for a long time, which may cause the pruning pole to slip from their hands when the hand is unstable. Utility Model Content

[0005] In view of the existing forestry branch pruning device in the patent, when pruning branches at high altitudes, the worker needs to hold the pruning pole with one hand and use an electric saw to prune the branches.

[0023] The specific technical solution includes a support rod 1; a placement frame 2 is fixedly installed at one end of the support rod 1, and a slot is opened on one side of the placement frame 2. An electric saw 3 is placed in the slot, and an electric saw base 4 is fixedly installed at the bottom of the electric saw 3. A clamping and fixing assembly 5 is provided on one side of the support rod 1. The clamping and fixing assembly 5 includes an arc plate 51, an arc connecting plate 52, a traction groove 53, a concave plate 54, a nut 55, a connecting block 56, a turntable 57, a connecting rod 58, a limiting groove 59, a pin 5010, and a limiting plate 5011. The arc plate 51 is located on one side of the support rod 1, the arc connecting plate 52 is inserted into the arc plate 51, a traction groove 53 is opened on one side of the arc plate 51, and the concave plate 54 is slidably connected in the traction groove 53.

[0024] Nut 55 passes through connecting block 56 and is threaded onto concave plate 54. A circular groove is provided on one side of connecting block 56, and an arc groove is provided on one side of the inner wall of the circular groove. Turntable 57 is slidably connected in the arc groove. The two ends of connecting rod 58 are rotatably connected to turntable 57 and support rod 1, respectively. The position of electric saw 3 at one end of support rod 1 can be adjusted at any time through turntable 57.

[0025] A limiting groove 59 is provided on one side of the arc-shaped connecting plate 52, and a limiting plate 5011 is rotatably connected to one side of the arc-shaped connecting plate 52 via a bearing. A circular hole is provided on the other side of the limiting plate 5011, and a pin 5010 passes through the circular hole and is inserted into the limiting groove 59. The pin 5010 allows the two arc-shaped connecting plates 52 to be connected together via the limiting plate 5011.

[0026] A return spring 7 is fixedly installed on one side of the inner wall of the mounting cavity, and the other end of the return spring 7 is fixedly installed on the locking block 6. A pull rod 8 is inserted into the placement frame 2, and the pull rod 8 passes through the mounting cavity and is fixedly installed on the locking block 6. A frosted rod 9 is fixedly installed on the other end of the support rod 1. With the return spring 7, when the chainsaw base 4 presses the locking block 6, the return spring 7 can be retracted, so that the chainsaw base 4 can be more easily locked in the placement frame 2.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, the curved plate 51 is attached to the appropriate position on the tree, and then the curved connecting plate 52 is stretched so that the curved connecting plate 52 and the curved plate 51 can surround the tree trunk. At this time, the limiting plate 5011 can be pulled so that the circular hole at one end of the limiting plate 5011 is aligned with the traction groove 53. Then the pin 5010 can be inserted to fix the pruning device on the tree. Then the worker can hold the abrasive rod 9. The design of the abrasive rod 9 can prevent it from slipping from the worker's hand. Then the support rod 1 at one end of the abrasive rod 9 can be moved. Since there are connecting rods 58 on both sides of the support rod 1, not only can the movement trajectory of the support rod 1 be controlled, but the worker can also move the electric saw 3 at one end of the support rod 1 more effortlessly. When it is necessary to move the position of the electric saw 3, it is only necessary to push the concave plate 54 so that the concave plate 54 can move around the curved plate 51. This makes it easier for the worker to hold the support rod 1 when pruning branches, and avoids the worker holding the support rod 1 for a long time, which can cause arm muscle soreness.

[0029] After use, the pin 5010 can be removed to allow the arc-shaped connecting plate 52 to enter the arc-shaped plate 51. Then, the nut 55 can be turned to separate the concave plate 54 and the connecting block 56. Then, the pull rod 8 can be pulled out to easily remove the electric saw base 4 that is stuck in the placement frame 2, making it easier to separate the support rod 1 and the electric saw 3. This makes the branch pruning device easier to assemble and disassemble, easier to transport, and greatly improves work efficiency.
