Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for fruit tree planting, specifically to a branch puller suitable for quantitative angle opening of apple trees. Background Technology

[0002] To ensure high yields, apple tree cultivation involves regular pruning and shaping. Typically, starting at a height of 80cm from the main trunk, about 10 lateral branches are retained in a spiral pattern. These lateral branches are then trained to achieve an opening angle of 90°-115°, creating a stable growth direction, improving ventilation within the row, facilitating mechanical operations, and controlling fruit production for optimal yield. Currently, apple tree lateral branch pruning uses an "S"-shaped branch trainer to fix new shoots, shaping them during growth. However, this trainer has significant drawbacks: it cannot precisely control the branch angle, only shaping along the growth trend, resulting in branch opening angles smaller than the predetermined range. Furthermore, the trainer requires frequent adjustments as the branches grow, leading to high manual labor costs. Therefore, this rudimentary branch trainer needs improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a branch puller suitable for quantitative branch opening on apple trees. This invention redesigns the branch puller's structure, focusing on its function of shaping and defining branches. It incorporates a foundation-based support and positioning structure to meet the operational requirements of branch opening on fruit trees. Furthermore, it includes position and angle adjustment mechanisms, facilitating the setting of target angles and the positioning and shaping of branches to maintain the predetermined branch opening angle on the apple tree, thereby increasing fruit tree yield.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base and two support rods, one on the left and one on the right of the base.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figure 1-5 As shown, the specific implementation adopts the following technical solution: This specific embodiment includes a base 1, a support rod 2, a lifting seat 3, a support threaded rod 7, and a positioning frame 6. A mounting threaded sleeve 15 is fixedly installed at each of the left and right ends of the base 1. A mounting threaded groove 16 is integrally formed on the lower side wall of the support rod 2. The support rod 2 is screwed into the mounting threaded sleeve 15 through the mounting threaded groove 16. Two lifting seats 3 are respectively fitted onto the support rods 2 on both sides, and the lifting seats 3 are arranged in an array. A lifting threaded sleeve is screwed onto the lower side wall of the lifting seat 3 via a bearing. 4. A lifting threaded groove 5 is integrally formed on the side wall of the support rod 2. The lifting threaded sleeve 4 is screwed onto the support rod 2 through the lifting threaded groove 5. A positioning block 10 is integrally formed on the inner wall of the lifting seat 3. A positioning groove 11 is also integrally formed on the side wall of the section of the support rod 2 with the lifting threaded groove 5. The positioning block 10 is slidably disposed in the positioning groove 11. At the same time, the length of the positioning block 10 is greater than twice the pitch of the lifting threaded groove 5. A threaded hole is opened on the lifting seat 3, and the threaded hole of the lifting seat 3 is open to... A support threaded rod 7 is threaded through the positioning frame 6, which is located on the side of the two lifting seats 3 in a set. One end of the positioning frame 6 is screwed with an adjusting threaded rod 19 via a bearing. An adjusting threaded sleeve 17 is hinged to one of the support threaded rods 7 in the set via a universal joint. The adjusting threaded sleeve 17 is threadedly fitted onto the adjusting threaded rod 19. A guide rod 20 is fixedly installed on the other end of the positioning frame 6. A guide sleeve 18 is hinged to the other support threaded rod 7 in the set via a universal joint. The guide sleeve 18 is movably fitted onto the guide rod 20. On the rod 20, several hanging holes 9 are arranged at equal intervals on the positioning frame 6. A connecting hook 8 is hung in the hanging hole 9. The connecting hook 8 is set with an "S" shaped structure. One of the hooks of the connecting hook 8 is inserted into the hanging hole 9. Positioning anchor rods 12 are movably inserted on both the left and right ends of the base 1. A handle is fixedly set on the upper end of the positioning anchor rod 12. A support plate 13 is fixedly set on one end of the base 1. The support plate 13 is set at a certain angle with the base 1. A support anchor rod 14 is movably inserted on the end of the support plate 13.

[0019] When using this device, install the base 1 according to the position of the fruit tree branch, so that after installing the support rod 2 on the base 1, the support rod 2 is positioned to the side of the fruit tree branch. Lay the base 1 on the ground, pass the positioning anchor rod 12 through the base 1 and screw it into the ground, and pass the support anchor rod 14 through the support plate 13 and screw it into the ground, thus completing the installation of the base 1. Next, screw the support rod 2 into the installation threaded sleeve 15 through the installation threaded groove 16, thus completing the installation of the support rod 2. Then, take a positioning frame 6 and screw the support threaded rods 7 at both ends of the positioning frame 6 into the threaded holes on a set of two left and right lifting seats 3. Then, adjust the positioning frame 6 so that the positioning frame 6 is positioned at the correct angle below the corresponding branch. Rotate the support threaded rods 7 to adjust the front and back position of the support threaded rods 7. Through the cooperation of the two left and right support threaded rods 7, the front and back positions of the left and right ends of the positioning frame 6 can be adjusted, thereby adjusting the angle and position of the positioning frame 6 in the horizontal direction, so that the positioning frame 6 is aligned with the corresponding fruit tree branch. The positioning frames 6 are nearly parallel on the horizontal plane, and different groups of positioning frames 6 are independently adjusted to position the positioning frame 6 with their corresponding branches. Rotating the lifting threaded sleeve 4 causes the lifting seat 3 to move on the support rod 2. The lifting seat 3 then drives the positioning frame 6 to move up and down through the support threaded rod 7. Through the coordinated up and down movement of the two left and right lifting seats 3 in one group, the vertical height position and the angle of the positioning frame 6 on the vertical plane are adjusted, and the vertical angle of the positioning frame 6 meets the approximately 110° angle range for branch pulling. Then, rotating the adjusting threaded rod 19 and adjusting the support of the adjusting threaded sleeve 17 allows the adjusting threaded rod 19 to move, that is, the adjusting threaded rod 19 drives the positioning frame 6 to move left and right, adjusting the left and right position of the positioning frame 6. When the positioning frame 6 moves left and right, it moves within the guide sleeve 18 through the guide rod 20, hooking one end of the connecting hook 8 onto the branch, and the other end of the connecting hook 8 hooks onto the hanging hole 9 on the positioning frame 6, thereby achieving branch pulling and shaping.

[0020] Compared with the prior art, the beneficial effects of this utility model are: 1. This device is designed for pulling fruit tree branches. It features an adjustable positioning frame 6 with several connecting hooks 8 on the positioning frame 6. After adjusting the position and angle of the positioning frame 6, the connecting hooks 8 can hook the branches and hang them on the positioning frame 6, thereby correcting the shape of the branches and adjusting the pulling angle of the branches. 2. This device is based on the positioning frame 6 that needs to be adjusted, and a lifting seat 3 that can be raised and lowered is set on the support rod 2. A threaded rod that can move back and forth is set on the lifting seat 3. By adjusting the threaded sleeve 17 and the guide sleeve 18 respectively, a set of two supporting threaded rods 7 are connected to the positioning frame 6, thereby realizing the adjustment of the position and angle of the positioning frame 6.

[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
