Description

Technical Field

[0001] The utility model relates to the technical field related to branch pruning, in particular to a forestry branch pruning device. Background Art

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is an important part of the national economy. The existing forestry branch pruning devices can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] The utility model patent with announcement number CN214902335U discloses a forestry branch pruning device, which belongs to the technical field related to branch pruning, and solves the problem that most of the existing technologies are traditional scissors-type designs. By using a longer grip rod, it is convenient to prune branches of different calibers. However, in actual use, when workers work for a long time, they may produce a lot of sweat, which will remain on the grip rod, and the sweat will reduce the friction between the grip rod and the palm, making it inconvenient for workers to continue using the device. The device includes a pruner and a grip rod. Two sets of grip rods are fixed on the pruner. The outer walls of the grip rods are all sleeved with sleeves. The outer walls of the grip rods are all provided with first external threads. The inner wall of the sleeve is provided with a first internal thread on the side facing the first external thread. The inner wall of the sleeve is glued with cleaning cotton on the side away from the first external thread. A limiting device is provided at the end of the grip rod away from the pruner. The sleeve, the first external thread, the first internal thread and the cleaning cotton cooperate with each other to avoid the problem that sweat remains on the grip, which reduces the friction between the grip and the palm and makes it inconvenient for workers to continue using the device, thereby improving the practicability of the device.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 7 , the present utility model details the above technical solutions through the following embodiments:

[0028] A forestry branch pruning device includes: a shearing box 1; a rectangular frame 2 is fixedly connected inside the shearing box 1, two first rotating shafts 3 are fixedly connected inside the rectangular frame 2, shearing plates 4 are fixedly connected to the outer surfaces of the middle parts of the two first rotating shafts 3, and knife heads 5 adapted to each other are fixedly connected to one side of the two adjacent shearing plates 4; a sliding mechanism 6 for controlling the synchronous rotation of the shearing plates 4 is arranged inside the shearing box 1; a telescopic mechanism 7 for adjusting the overall length of the device is arranged on one side of the shearing box 1. The staff controls the two shearing plates 4 to rotate around the first rotating shaft 3 through the sliding mechanism 6, so that when the two shearing plates 4 approach each other, the knife heads 5 are driven, and the two knife heads 5 prune the branches. This not only enables the device to automatically prune the branches, but also enables the device to be relatively fast and labor-saving when pruning branches with a relatively thick diameter, solving the problem that the existing forestry branch pruning device does not have the function of automatically pruning branches, resulting in the staff having to manually prune branches with a relatively large diameter, which is relatively laborious and the pruning speed is slow, reducing the work efficiency of the staff.

[0029] AsFigure 3 As shown in the figure, the sliding mechanism 6 includes: a circular plate 8 is arranged inside the shearing box 1, a first cylindrical block 9 is fixedly connected to one side of the circular plate 8, a moving frame 10 adapted to the outer surface of the first cylindrical block 9 is arranged, a connecting rod 11 is fixedly connected to one side of the moving frame 10, one end of the connecting rod 11 away from the moving frame 10 penetrates through the rectangular frame 2 and extends to the moving rack 12, and the connecting rod 11 is fixedly connected to the moving rack 12; second cylindrical blocks 13 are fixedly connected to the moving rack 12 near the shearing plate 4, and stroke grooves 14 adapted to the second cylindrical blocks 13 are respectively formed in the shearing plate 4 near the second cylindrical blocks 13; a labor-saving mechanism 15 for reducing the energy consumption of the device is arranged at the center of the circular plate 8. When the labor-saving mechanism 15 is started, the labor-saving mechanism 15 drives the circular plate 8 to rotate. While the circular plate 8 rotates, it drives the first cylindrical block 9. While the first cylindrical block 9 makes a circular motion, it drives the moving frame 10. The moving frame 10 drives the connecting rod 11, so that the connecting rod 11 slides horizontally inside the shearing box 1. While the connecting rod 11 slides, it drives the moving rack 12. The moving rack 12 drives the second cylindrical block 13. While the second cylindrical block 13 moves in the stroke groove 14 inside the shearing plate 4, it drives the shearing plate 4, so that the two shearing plates 4 rotate around the first rotating shaft 3 at the same time.

[0030] As Figure 4 shown in the figure, the labor-saving mechanism 15 includes: a second rotating shaft 16 is fixedly connected to the center of the circular plate 8. One end of the second rotating shaft 16 away from the circular plate 8 penetrates through the shearing box 1 and extends to the first gear 17. The second rotating shaft 16 is rotatably connected to the shearing box 1. The first gear 17 is fixedly connected to the second rotating shaft 16. A second gear 18 is meshed with one side of the first gear 17. The diameter of the second gear 18 is smaller than that of the first gear 17. A third rotating shaft 19 is fixedly connected to the center of the second gear 18; one end of the third rotating shaft 19 away from the second gear 18 penetrates through the gear box 20 and extends to the motor 21. The motor 21 is fixedly connected to the gear box 20. The gear box 20 is fixedly connected to the shearing box 1. The third rotating shaft 19 is fixedly connected to the output end of the motor 21. When the motor 21 is started, the output end of the motor 21 drives the third rotating shaft 19. The third rotating shaft 19 drives the second gear 18. The second gear 18 drives the first gear 17 to rotate. While the first gear 17 rotates, it drives the second rotating shaft 16. The second rotating shaft 16 drives the circular plate 8 to rotate, achieving the purpose of labor saving, so that the device can be relatively fast and labor-saving when pruning branches with a relatively thick diameter.

[0031] As Figure 2 shown in the figure, a limiting sleeve 22 is slidably connected to the outer surface of the connecting rod 11 near the rectangular frame 2. The limiting sleeve 22 is fixedly connected to the shearing box 1, which can limit the connecting rod 11 and enable the connecting rod 11 to slide horizontally inside the shearing box 1.

[0032] As Figure 5As shown in the figure, the telescopic mechanism 7 includes: One side of the shear box 1 is fixedly connected with a telescopic rod 23, and a hollow tube 24 adapted to the outer surface of the telescopic rod 23 is sleeved; A silica gel sleeve 25 is fixedly connected to the outer surface of the end of the hollow tube 24 away from the shear box 1; A locking mechanism 26 for fixing the telescopic rod 23 is arranged at one end of the hollow tube 24 close to the shear box 1. The staff can pull out the telescopic rod 23 from the inside of the hollow tube 24, and then lock and fix the pulled-out telescopic rod 23 through the locking mechanism 26.

[0033] As Figure 6 shown in the figure, the locking mechanism 26 includes: Four pressing plates 27 are arranged at one end of the hollow tube 24 close to the shear box 1, and the pressing plates 27 are fixedly connected to the hollow tube 24. An internal thread sleeve 28 is threadedly connected to the outer surface of the end of the hollow tube 24 close to the pressing plate 27; A pressing ring 29 is arranged at one end of the internal thread sleeve 28 close to the pressing plate 27, and the pressing ring 29 is fixed to the inner wall of the internal thread sleeve 28. The pressing ring 29 cooperates with the pressing plate 27. The staff rotates the internal thread sleeve 28, the internal thread sleeve 28 drives the pressing ring 29, and the pressing ring 29 squeezes the pressing plate 27 through an inclined surface, so that the pressing plate 27 squeezes the telescopic rod 23, thereby locking and fixing the telescopic rod 23.

[0034] As Figure 7 shown in the figure, two sliders 30 are fixedly connected to the end of the telescopic rod 23 away from the shear box 1, and sliding grooves 31 adapted to the sliders 30 are respectively formed in the hollow tube 24 close to the sliders 30, which can limit the moving stroke of the telescopic rod 23 and avoid the separation of the telescopic rod 23 from the hollow tube 24.

[0035] Working principle: Start the motor 21. The output end of the motor 21 drives the third rotating shaft 19. The third rotating shaft 19 drives the second gear 18. The second gear 18 drives the first gear 17 to rotate. While the first gear 17 rotates, it drives the second rotating shaft 16. The second rotating shaft 16 drives the circular plate 8 to rotate itself, achieving the purpose of labor saving. While the circular plate 8 rotates, it drives the first cylindrical block 9. While the first cylindrical block 9 makes a circular motion, it drives the moving frame 10. The moving frame 10 drives the connecting rod 11, causing the connecting rod 11 to slide horizontally inside the shearing box 1. While the connecting rod 11 slides, it drives the moving frame 12. The moving frame 12 drives the second cylindrical block 13. While the second cylindrical block 13 moves in the stroke groove 14 inside the shearing plate 4, it drives the shearing plate 4, causing the two shearing plates 4 to rotate simultaneously around the first rotating shaft 3. While the two shearing plates 4 approach each other, they drive the cutter heads 5, causing the two cutter heads 5 to prune the branches. This not only enables the device to automatically prune the branches but also makes the device relatively fast and labor-saving when pruning thicker branches, solving the problem that the existing forestry branch pruning devices do not have the function of automatically pruning branches, resulting in the fact that it is laborious for workers to manually prune thicker branches, and the pruning speed is slow, reducing the work efficiency of the workers.

[0036] The worker can pull out the telescopic rod 23 from the inside of the hollow tube 24, and then rotate the internal thread sleeve 28. The internal thread sleeve 28 drives the pressure ring 29. The pressure ring 29 squeezes the pressure plate 27 through the inclined surface, causing the pressure plate 27 to squeeze the telescopic rod 23, thereby locking and fixing the telescopic rod 23. This allows the worker to adjust the overall length of the device when pruning branches at a higher height, facilitating the user to prune the branches at a higher position, and solving the problem that it is inconvenient to prune the branches at a higher position with the existing forestry branch pruning devices.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
