Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for fruit tree cultivation, and more specifically, to a fruit tree branch pulling device. Background Technology

[0002] Pears are a common fruit in northern my country, with varieties like Laiyang pears and Qiuyue pears being popular and high-quality. Pear cultivation is an important branch of fruit tree cultivation. Branch training is a core management technique in pear tree cultivation, its main purpose being to adjust the angle of branch spread to optimize ventilation and light penetration within the tree, thereby promoting flower bud differentiation and improving fruit quality and yield. Currently, existing branch training techniques mainly rely on two methods, both of which have significant drawbacks: 1. Flexible Fixing Method: This method involves directly binding and fixing branches with ropes, wires, or bamboo poles. This method has three main problems: First, it is prone to slipping, making it impossible to maintain the preset angle for a long time, leading to uncontrolled branch pulling; second, the wires and ropes are in direct contact with the bark, easily damaging the branch surface, disrupting the tree's nutrient transport channels, and even causing branch rot; third, manual operation is cumbersome, requiring re-untying and re-fixing when adjusting the angle, resulting in low efficiency.

[0003] 2. Rigid support fixing solution: This solution employs screw-adjustable clamps and integrated fixing brackets. While it solves the "slippage" problem, it still has limitations: First, angle adjustment relies on a "disassembly-adjustment-reassembly" process, making it impossible to fine-tune the angle without disassembling the device; second, the rigid structure cannot adapt to the minor deformations during the growth of fruit tree shoots (such as thickening or slight bending of branches), easily leading to localized stress concentration on the branches, causing branch breakage or abnormal growth.

[0004] In summary, existing technologies lack a branch-pulling device that can adapt to the dynamic characteristics of fruit tree growth, enable convenient angle adjustment, and protect branches. There is an urgent need for technological improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fruit tree branch pulling device to solve the problems of inconvenient operation and inability to adapt to the dynamic growth characteristics of fruit trees in the prior art. This device can adapt to trunks and branches of different thicknesses, avoid damaging the tree, and is convenient to adjust the angle and pulling force without the need for overall disassembly. At the same time, it can adapt to the dynamic deformation of fruit tree growth and reduce stress concentration on branches.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fruit tree branch-pulling device includes a support base, a positioning component, a support arm, a hinge, and an adjustable branch-pulling connector; The support base is a ring-shaped structure used to be fitted onto the trunk of the fruit tree; The positioning components are provided in several groups, evenly distributed on the support base, and are used to cooperate with the support base device to fix the whole to the trunk of the fruit tree. The arm is provided in several groups, circumferentially arranged at equal angles on the outside of the support base. Its lower end is adjustablely connected to the support base through a hinge, and its upper end is provided with an adjustable branch connector for connecting to tree branches. The adjustable branch-pulling connector includes a branch-pulling head, a pull rope, a take-up reel, a reel base, an adjusting shaft, and a locking assembly. The reel base has a U-shaped structure and is fixed to the upper end of the support arm. The reel base has a take-up reel inside, which is rotatably connected to the reel base via the adjusting shaft. The pull rope is wound on the take-up reel to provide pulling force for pulling the branch. The end of the pull rope is connected to a branch-pulling head for connecting to the branch.

[0007] Furthermore, the support base consists of two semi-circular retaining rings, and the connection between the two retaining rings is detachably connected by a buckle.

[0008] Furthermore, the positioning component includes a handle, a screw, and a top pressure plate; the screw passes through and is screwed to a fixing ring, the outer end of the fixing ring is provided with a handle, and the inner end of the fixing ring is rotatably connected to the top pressure plate.

[0009] Furthermore, the top pressure plate is made of plastic, and a rubber cushioning pad is attached to the side of the plate near the center of the support base, and the surface of the rubber cushioning pad is engraved with anti-slip texture.

[0010] Furthermore, the hinge component includes a movable hinge joint, a fixed hinge joint, and a hinge adjustment bolt; the fixed hinge joint is fixed to the outer circumferential surface of the fixing ring of the support base, the movable hinge joint is fixed to the lower end of the support arm, and the movable hinge joint and the fixed hinge joint are connected and adjusted by the hinge adjustment bolt.

[0011] Furthermore, the locking assembly includes a support spring, a ratchet seat, a ratchet chuck, and a knob; the right end of the adjusting shaft is movably fitted with a ratchet seat, a support spring is fitted on the adjusting shaft in the area between the ratchet seat and the disc seat, the right end of the adjusting shaft is fixed with a ratchet chuck adapted to the ratchet seat, the ratchet chuck is engaged with the ratchet seat, and the right end of the ratchet chuck is fixed with a knob.

[0012] Furthermore, the branch-pulling head includes a hook and a pull plate; the pull plate is fixedly connected to the end of the pull rope, and two sets of hooks are symmetrically provided on the upper surface edge of the pull plate for hanging and connecting to the branch.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1: As Figures 1 to 7 As shown, this embodiment provides a fruit tree branch pulling device, including a support base 4, a positioning component 5, a support arm 2, a hinge 3, and an adjustable branch pulling connector 1.

[0029] The support base 4 is a ring structure used to fit and fix the entire device to the trunk of the fruit tree. The support base 4 consists of two semi-circular fixing rings 41. The connection between the two fixing rings 41 is detachable by a buckle 42. This makes it easy to fit onto trunks of different thicknesses and allows for quick assembly and disassembly through the buckle 42, adapting to changes in trunk diameter.

[0030] The positioning components 5 are provided in four sets, evenly distributed along the circumference of the support base 4, and are used to fix the entire device of the support base 4 to the trunk of the fruit tree. The positioning components 5 include a handle 51, a screw 52 and a top pressure plate 53. The screw 52 passes through the fixing ring 41 and is screwed to it. The outer end of the fixing ring 41 is provided with a handle 51, and the inner end of the handle is rotatably connected to the top pressure plate 53. The rotatable connection can prevent the top pressure plate 53 from rotating and rubbing against the bark when the screw 52 rotates. Rotating the handle 51 can drive the screw 52 to move radially, causing the top pressure plate 53 to press against the surface of the trunk, thereby clamping and fixing the device to the trunk.

[0031] The top pressure plate 53 is made of plastic, and a rubber buffer pad is attached to the side of it close to the main trunk. The surface of the buffer pad is engraved with anti-slip textures, which not only enhances the friction with the main trunk and prevents the device from sliding, but also avoids damaging the skin of the main trunk through the elastic deformation of the rubber.

[0032] Support arm 2 has several sets, the number of which matches the number of branches to be pulled, preferably 3-6 sets, and is distributed circumferentially at equal angles along the outside of support base 4. It is the intermediate structure connecting support base 4 and adjustable branch pulling connector 1. Its lower end is adjustablely connected to support base 4 through hinge 3, and the upper end is fixed to adjustable branch pulling connector 1. Its core function is to transmit tension and adjust the branch pulling direction.

[0033] The hinge component 3 includes a movable hinge joint 31, a fixed hinge joint 32, and a hinge adjustment bolt 33. The fixed hinge joint 32 is welded to the outer circumferential surface of the fixed retaining ring 41, and the movable hinge joint 31 is welded to the lower end of the support arm 2. The movable hinge joint 31 and the fixed hinge joint 32 are connected by a pin. Loosening the hinge adjustment bolt 33 allows the support arm 2 to be rotated to adjust the tilt angle, and tightening the bolt locks the angle. This allows for fine-tuning of the direction of the support arm 2 without disassembly, thereby further adjusting the angle of the branch.

[0034] In addition, the adjustable branch connector 1 is located at the upper end of the support arm 2 and is used to directly connect with the target branch to realize branch adjustment; the adjustable branch connector 1 includes a branch head 11, a pull rope 12, a winding reel 13, a reel base 14, an adjusting shaft 15 and a locking component 16. The tray base 14 is a U-shaped structure, which is fixed to the upper end of the support arm 2 by welding, providing installation support for the winding tray 13.

[0035] The winding reel 13 is located inside the reel base 14 and is rotatably connected to the reel base 14 by adjusting the rotating shaft 15. The surface is provided with a rope winding groove for winding the pull rope 12.

[0036] The pull rope 12 is made of high-strength nylon rope, which is both tough and flexible, to avoid breaking or damaging the branches. One end is fixed and wound on the winding reel 13, and the other end is connected to the branch pull head 11.

[0037] The branch pull head 11 is used to connect with the branch, including a pull plate 112 and a pull hook 111; the pull plate 112 and the end of the pull rope 12 are fixed by a buckle. The upper surface edge of the pull plate 112 is symmetrically provided with two sets of pull hooks 111—the double hook design can enhance the connection stability with the branch, and the outside of the pull hook 111 is covered with a silicone sleeve. The elasticity of the silicone can prevent the pull hook 111 from directly scratching the bark of the branch.

[0038] The locking assembly 16 is used to lock the rotational position of the take-up reel 13, preventing the pull rope 12 from loosening, while allowing unidirectional fine-tuning to adapt to growth deformation. Its structure includes a support spring 161, a ratchet seat 162, a ratchet chuck 163, and a knob 164; the ratchet seat 162 is movably sleeved on the right end of the adjusting shaft 15, and the support spring 161 is sleeved on the adjusting shaft 15 between the ratchet seat 162 and the reel seat 14 to provide elastic preload, and the two ends of the support spring 161 are fixedly connected to the ratchet seat 162 and the reel seat 14 respectively; a ratchet chuck 163 adapted to the ratchet seat 162 is welded to the right end of the adjusting shaft 15, and the two are engaged; a knob 164 is welded to the right end of the ratchet chuck 163.

[0039] Among them, the ratchet teeth on the ratchet seat 162 and the ratchet teeth on the ratchet chuck 163 are both oblique teeth, and their inclination directions are opposite.

[0040] The working principle of the locking component 16 is as follows: Turning the knob 164 clockwise drives the adjusting shaft 15 and the winding reel 13 to rotate, winding up the pull rope 12 to increase the pulling force; at this time, the meshing structure of the ratchet chuck 163 and the ratchet seat 162 can prevent the adjusting shaft 15 from rotating in the opposite direction, thus achieving tension locking; when it is necessary to reduce the pulling force, press the ratchet seat 162 to separate it from the ratchet chuck 163, then turn the adjusting knob 164 to adjust the pull rope 12 to an appropriate length, and then release the ratchet seat 162. Under the elastic force of the support spring 161, the ratchet seat 162 returns to its original position and meshes with the ratchet chuck 163, thus relocking.

[0041] Example 2: This example provides the working principle of a fruit tree branch pulling device: In actual use, firstly, the two semi-circular fixing rings 41 are respectively fitted onto both sides of the main trunk of the fruit tree, so that the buckles 42 are aligned and fastened; then, the handles 51 of each group of positioning components 5 are rotated in sequence, and the screws 52 are driven to push the top pressure plate 53 towards the main trunk until the rubber buffer pad of the top pressure plate 53 is tightly attached to the main trunk and the support base 4 is not loose, thus achieving the fixation of the fixed support base 4 and the entire device. According to the position of the branch to be pulled, loosen the hinge adjustment bolt 33 at the lower end of the corresponding support arm 2; rotate the support arm 2 so that the adjustable branch pulling connector 1 at the upper end of the support arm 2 is aligned with the target branch; tighten the hinge adjustment bolt 33 to lock the angle of the support arm 2. Release the locking state of the winding reel 13, release the pull rope 12 of sufficient length, and hang the branch head 11 on the branch through the pull hook 111; turn the knob 164 clockwise to drive the adjusting shaft 15 and the winding reel 13 to rotate, gradually winding up the pull rope 12 and observing the change in the branch angle; when the branch reaches the preset opening angle, stop turning the knob 164. At this time, the ratchet chuck 163 and the ratchet seat 162 are engaged and locked under the action of the support spring 161, and the pulling force remains stable.

[0042] During the growth of fruit trees, such as when branches thicken or new shoots grow, the support spring 161 of the locking component 16 can provide a slight elastic buffer, allowing the ratchet chuck 163 to rotate slightly in one direction, so that the pull rope 12 is slightly relaxed and the stress on the branches is released; if further angle adjustment is required, simply turn the knob 164 again to fine-tune the tension.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
