Description

Technical Field

[0001] This application relates to the field of equipment for afforestation and pruning, and more specifically, to a branch pruning device for afforestation. Background Technology

[0002] During afforestation, forest cultivation, and forest protection activities, staff frequently need to scientifically and rationally prune tree branches to ensure the healthy growth of trees. However, traditional manual pruning methods have significant limitations: on the one hand, working at heights relies on ladders or lifting equipment, which is not only inefficient but also poses safety hazards; on the other hand, ordinary pruning tools struggle to precisely control the angle and depth of cuts, easily causing bark tears or xylem damage, affecting the quality of wound healing. Therefore, afforestation branch pruning devices have been increasingly widely used.

[0003] The prior art publication number CN222442414U provides a forestry branch pruning device. This device, by setting up pruning components, can quickly and automatically prune and cut branches, avoiding the time-consuming and laborious manual operation of hand-held pruning shears. It is simple and quick to operate, thus improving the pruning efficiency of the device.

[0004] While the existing technical solutions described above improve the efficiency of pruning tree branches to some extent, they still have the following drawbacks: These solutions primarily rely on electric motors and hydraulic cylinders as power sources, but power supply is a frequent challenge in forestry operations. If batteries are used, their limited range makes it difficult to support long-term, large-scale pruning operations; if fuel is used, there are issues with noise, emissions, and the need to carry fuel, while a completely manual method is extremely physically demanding and cannot guarantee pruning efficiency. Therefore, we propose a branch pruning device for forest management. Utility Model Content

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings. Reference Figure 1 and Figure 2This application discloses a pruning device for forest management, comprising: a support block 1, a first telescopic rod 3 fixedly installed below the support block 1, a tree clamping fastener installed above the support block 1, the tree clamping fastener including an installation box 2 fixedly installed on one side of the support block 1, lifting blocks 6 installed on both sides of the installation box 2, an anti-fall groove 601 opened at the inner end of the lifting block 6, a driving mechanism installed on one side of the installation box 2, the driving mechanism being used to drive the lifting block 6 to move linearly, and a pruning device installed on the other side of the support block 1, the pruning device including a sliding sleeve 12 movably installed on the other side of the support block 1, a second telescopic rod 5 slidably connected inside the sliding sleeve 12, and a tree sawing device 10 detachably installed at the end of the second telescopic rod 5.

[0020] The drive mechanism includes a first motor 11, and a bidirectional lead screw 9 is fixedly connected to the output end of the first motor 11. Both sides of the bidirectional lead screw 9 are threadedly connected to movable blocks 4. The movable blocks 4 are constrained by the mounting box 2 and slidably connected to it. The movable blocks 4 are connected and fixed to the corresponding lifting blocks 6. Although the first motor 11 is used here, the first motor 11 here only serves as a drive and clamping function, and does not need to consume too much power to achieve the purpose of use.

[0021] A mounting groove 101 is provided on the other side of the bearing block 1. A spherical connecting block 13 is rotatably connected in the mounting groove 101. The end of the spherical connecting block 13 is connected and fixed to the sliding sleeve 12.

[0022] The worker places the lifting block 6 on both sides of the branch to be pruned. Under the action of the first motor 11, the movable block 4 drives the lifting block 6 to move from both sides to the middle until it is in close contact with the branch, thus firmly hanging the device on the branch. Then, the user holds the second telescopic rod 5 to adjust the position of the tree sawing device 10 and saws off the branch to be pruned. In this way, the pruning of high branches can be completed without relying on too many external power sources and without making the workers too tired. It is suitable for pruning branches during field forestry.

[0023] Reference Figure 2 A protective pad 7 is adhered and fixed to the inner side of the anti-fall groove 601. The protective pad 7 is made of silicone material. The protective pad 7 can prevent the lifting block 6 from excessively squeezing the inner side of the branch and causing damage to the tree.

[0024] Reference Figure 1 and Figure 3The second telescopic rod 5 is equipped with a connecting component 8 at its end. The connecting component 8 includes a placement box 801 fixedly installed at the end of the second telescopic rod 5. Several screws 802 are threadedly connected to the placement box 801. The ends of the screws 802 are rotatably connected to a limit plate 803, which allows the workers to replace the tree sawing equipment 10 according to the actual situation. Both electric equipment and manual saws can be used, which greatly improves the applicability of this technical solution.

[0025] This application, by setting up a lifting block 6, a second telescopic rod 5, and a drive mechanism, can complete the pruning of branches at high altitudes without relying on too many external power sources and without causing excessive fatigue to the staff. It is suitable for pruning branches during field forestry operations. At the same time, by setting up a protective pad 7, it can prevent the lifting block 6 from excessively squeezing the inside of the branches and causing damage to the trees. In addition, by setting up a connecting component 8, it is easy for the staff to replace the tree sawing equipment 10 according to the actual situation.

[0026] The implementation principle of the afforestation branch pruning device in this embodiment is as follows: When relevant personnel need to use this technical solution to prune branches at high locations, the personnel first place the handheld side of the sawing device 10 into the placement box 801 and turn the screw 802 inward until the limiting plate 803 securely installs the sawing device 10. Then, the user places the lifting block 6 on both sides of the branch to be pruned. Under the action of the first motor 11, the movable block 4 drives the lifting block 6 to move from both sides towards the middle until it is in close contact with the branch, thus firmly hanging the device on the branch. Then, the user holds the second telescopic rod 5 to adjust the position of the sawing device 10 and saws off the branch to be pruned. In this way, the personnel can complete the operation of pruning branches at high locations.
