Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fruit tree branch pulling equipment, specifically a fruit tree branch pulling angle opening device. Background Technology
[0002] Branch training is one of the shaping methods for fruit trees. It involves artificially altering the growth angle and distribution direction of branches. Branch training plays a crucial role in cultivating the tree's skeletal structure, optimizing branch spatial distribution, improving light and ventilation conditions, altering branch polarity, adjusting branch vigor, promoting or inhibiting branch growth, and resolving the conflict between fruit tree growth and fruit production.
[0003] For example, a fruit tree branch-pulling and angle-opening device, disclosed in CN216492186U, includes a telescopic rod with one end hinged to a fixing member and the other end detachably connected to a hook device. The telescopic rod includes a first rod body and a second rod body, with the second rod body movably inserted into the first rod body. The end of the first rod body opposite to the second rod body is hinged to the fixing member, and the end of the second rod body opposite to the first rod body is detachably connected to the hook device. When pulling branches on a fruit tree, the fixing member is first inserted into the ground, and then the branch is hooked up using the hook device. The length of the second rod body inserted into the first rod body is adjusted according to the required branch-pulling angle and the branch's bearing capacity, so that the force applied to the branch by this invention is moderate and adjustable. During the subsequent growth of the fruit tree, the force applied to the branch by this invention can also be adjusted at any time, thereby effectively avoiding damage or breakage of the branch.
[0004] The aforementioned patent proposes to shape fruit tree branches by inserting a fixing component into the ground and hanging the branch with a hook. However, the fixing component lacks lateral restraint function during insertion into the ground. Consequently, during the shaping process, the fixing component is prone to loosening from the ground under the pull of the branch, affecting the subsequent shaping effect of the fruit tree.
[0005] Therefore, we propose a fruit tree branch-pulling and angle-opening device to solve the problems mentioned above. Utility Model Content

[0024] Please see Figure 1-4 A fruit tree branch pulling and angle opening device includes a base 1, a fixed cone 2 fixedly installed at the bottom center of the base 1, a cavity opened on the base 1, an adjustment box 3 fixedly installed at the top center of the base 1, a handle 4 provided at the top center of the adjustment box 3, a tension rope 5 fixedly installed at the bottom of the handle 4 (the top of the adjustment box 3 has a through opening, and the tension rope 5 passes through the inner cavity of the through opening), a winding roller 6 is provided in the inner cavity of the adjustment box 3, and the tension rope 5 is wound around the outer circumference of the winding roller 6, one end of the tension rope 5 is fixedly connected to the outer circumference of the winding roller 6, an adjustment component is provided on one side of the adjustment box 3, and a limit component is provided in the inner cavity of the fixed cone 2.
[0025] The limiting assembly includes a knob 16 located on the top of the base 1 near one side and a worm 17 fixedly installed at the center of the bottom of the knob 16. The bottom end of the worm 17 movably passes through the top of the cavity and is rotatably connected to the bottom of the cavity. A worm wheel 18 is meshed on the front side of the worm 17 near the bottom end. A straight rod 19 is provided through the center of one side of the worm wheel 18, and the other end of the straight rod 19 is rotatably connected to the side wall of the cavity.

The bottom end of the vertical rod 22 movably passes through the bottom of the cavity and is fixedly installed with a rotating bevel gear 23. Both sides of the rotating bevel gear 23 are meshed with movable bevel gears 24. Threaded tubes 25 are fixedly installed on the opposite side of the movable bevel gears 24. Threaded rods 27 are threadedly connected to the inner cavity of the threaded tubes 25. A horizontal cone 28 is fixedly installed on the opposite end of the threaded rods 27 (the cross section of the horizontal cone 28 is T-shaped). Rectangular openings are opened on both sides of the fixed cone 2 near the middle position, and the ends of the horizontal cone 28 are located in the inner cavities of adjacent rectangular openings.
[0026] Specifically, when the fixed cone 2 is inserted into the ground, the rotating bevel gear 23 can be rotated with the help of the limiting component, which in turn can rotate the two movable bevel gears 24 that mesh with the rotating bevel gear 23. While the movable bevel gears 24 are rotating, the adjacent threaded tube 25 can be rotated.

[0030] Specifically, the movement of the transverse cone 28 can be limited by setting the fixing block 29 and the round rod 30. Example
[0031] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 and Figure 4 The adjustment assembly includes a fixed shaft 7 and a hand crank 8 fixedly installed at one end of the fixed shaft 7. The other end of the fixed shaft 7 movably passes through one side of the inner cavity of the adjustment box 3 and is rotatably connected to the other side of the inner cavity of the adjustment box 3. The outer periphery of the take-up roller 6 is fixedly sleeved on the outer periphery of the fixed shaft 7. A limiting plate 9 is fixedly sleeved near one end of the outer periphery of the fixed shaft 7. Several limiting holes 10 are opened on the outer periphery of the limiting plate 9. The several limiting holes 10 are arranged in a circular array with the center of the other side of the limiting plate 9 as the center. Insert rods 11 are movably inserted into the inner cavity of adjacent limiting holes 10. Movable blocks 12 are fixedly installed at the bottom end of the insert rods 11. Telescopic rods 14 are fixedly installed at the bottom of the movable blocks 12 near both sides. The bottom ends of the telescopic rods 14 are fixedly connected to the base 1.
[0032] Specifically, when shaping fruit tree branches, the fixed shaft 7 can be rotated with the help of the adjusting components, which in turn allows the winding roller 6, which is fixedly sleeved on the outer periphery of the fixed shaft 7, to rotate and wind up the tension rope 5, thereby shaping the fruit tree branches. Furthermore, by setting the spring 15, the telescopic rod 14, and the movable block 12, the insertion rod 11 can be inserted into the inner cavity of the limiting hole 10, thereby limiting the limiting plate 9 and preventing the fixed shaft 7 from loosening due to self-rotation, which would affect the subsequent fruit tree shaping effect.
[0033] Springs 15 are movably sleeved on the outer periphery of the telescopic rod 14, and the top and bottom ends of the springs 15 are fixedly connected to the movable block 12 and the base 1, respectively.
[0034] Specifically, by setting the spring 15, the insertion rod 11 can be stably inserted into the inner cavity of the limiting hole 10.
[0035] A toggle block 13 is fixedly installed on the front side of the movable block 12, and the top of the toggle block 13 is arc-shaped.
[0036] Specifically, the movable block 12 can be moved downwards by setting the toggle block 13.
[0037] Working Principle: In use, the base 1 is placed in the desired position, and then the fixed cone 2 is inserted into the ground. Rotating the knob 16 rotates the worm gear 17 fixed to it. The worm wheel 18 meshing with the worm gear 17 rotates the straight rod 19. Driven by the driving bevel gear 20 and the driven bevel gear 21, the vertical rod 22 rotates. The rotating bevel gear 23 fixed to the vertical rod 22 rotates the two meshing movable bevel gears 24, which in turn rotate the threaded tube 25 fixed to the movable bevel gears 24. The threaded rod 27, threaded into the inner cavity of the threaded tube 25, causes the horizontal cone 28 to move to the opposite side under the constraint of the fixed block 29 and the round rod 30. This improves the stability of the fixed cone 2 when inserted into the ground. Then, with the cooperation of the handle 4 and the tension rope 5, the branch to be shaped is tied together. Then, the actuating block 13 can be pushed down, which can cause the movable block 12 fixed on the actuating block 13 to move down and compress the telescopic rod 14 and the spring 15. Rotating the hand crank 8 can cause the fixed shaft 7 fixed on the hand crank 8 to rotate, which in turn causes the winding roller 6 fixed on the outer circumference of the fixed shaft 7 to rotate and wind up the tension rope 5, thereby shaping the fruit tree branch. When the branch is bent to a suitable position, the actuating block 13 can be released. Under the elastic force of the spring 15, the insertion rod 11 can be inserted into the inner cavity of the limiting hole 10, which can limit the limiting plate 9 and prevent the fixed shaft 7 from rotating loosely, affecting the subsequent fruit tree shaping effect.
