Description

Technical Field

[0001] This utility model relates to the field of fruit tree branch pulling technology, specifically a fruit tree branch pulling device. Background Technology

[0002] As a crucial component of modern agriculture, fruit tree cultivation's management techniques, particularly the level of precision and mechanization, directly impact fruit yield, quality, and production efficiency. Among numerous fruit tree management techniques, "branch training" is a vital and widely applied shaping and pruning method. It artificially guides branches to change their natural growth direction and angle, thereby optimizing tree structure, improving ventilation and light penetration within the canopy, and effectively regulating the balance between vegetative and reproductive growth. This lays a solid foundation for promoting flower bud differentiation, improving fruit quality, and facilitating field operations. Traditional branch training methods rely heavily on binding and securing with ropes, wires, and other basic materials. While this meets production needs to some extent, there is still significant room for improvement and innovation in terms of long-term reliability, humanized adaptation to tree growth, and ease of operation.

[0003] Traditional branch-pulling operations often involve binding branches with ropes, with one end fixed to the ground or a low section of the trunk. While simple and easy to implement, the ropes or wires used for binding the branches have a fixed tension and cannot adapt to the gradual expansion of the branches as they thicken. During growth, the branches are severely restricted by the binding material, resulting in constrictions. This not only damages the phloem and hinders nutrient transport, affecting the normal growth of the tree, but can also lead to the death of the distal branch in severe cases. Furthermore, the connection between the other end of the branch and the ground usually relies on temporary nails or weights. The length of the pulling rope is mostly adjusted by knotting, which is cumbersome and makes it difficult to precisely control the branch-pulling angle. Different fruit tree varieties, ages, and shaping requirements necessitate different branch-pulling angles, and the fixed rope length makes it difficult to adjust quickly and flexibly, affecting the efficiency and quality of branch-pulling operations. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a fruit tree branch puller, which solves the technical problem that the existing fruit tree branch pullers cannot adaptively expand as the branches of the fruit tree thicken year by year, and the branches are severely restricted by the binding material during the growth process, forming constrictions, which not only damages the phloem and hinders nutrient transport, but also affects the normal growth of the tree.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: This utility model provides a fruit tree branch pulling device, comprising: Mounting bracket, used for insertion and fixing to the ground; The junction box has a traction rope wound inside, and its bottom is slidably connected to the mounting bracket. The extension and retraction adjustment mechanism, located inside the junction box, is used to adjust the length of the traction rope; The fixing box has a strap wound inside, and the traction rope inside the hub box is connected to the bottom of the fixing box; The outer end of the binding strap engages with the outer circumference of the fixing box to form a binding ring for the branch. The binding strap can extend out of the fixing box as the branch grows and thickens, thus providing adaptive binding for the branch.

[0006] Optionally, a mounting rod is rotatably mounted inside the fixing box, and a strap is wound around the mounting rod; Both ends of the mounting rod are fitted with disc springs, and the inner and outer ends of the disc springs are connected to the mounting rod and the fixing box, respectively. A ratchet is fitted onto the mounting rod, and a pawl that meshes with the ratchet is rotatably mounted inside the fixing box. The pawl is rotatably connected to the fixing box via a rotating rod. A torsion spring is fitted onto the rotating rod, and the two ends of the torsion spring are fixedly connected to the pawl and the fixed box, respectively.

[0007] Optionally, a gear is also sleeved on the rotating rod, a rack that meshes with the gear is slidably installed in the fixed box, and a slide rod that guides the rack is fixedly installed in the fixed box, with the rack slidably sleeved on the slide rod; Two sets of symmetrically distributed first springs are mounted on the slide rod, and the two ends of the two sets of first springs are fixedly connected to the rack and the fixed box, respectively.

[0008] Optionally, the retraction and extension adjustment mechanism includes: A sliding carriage is installed inside the junction box. A sleeve is fixedly installed between the carriage and the junction box, and a disc spring is fixedly sleeved on the sleeve. The winding rod is coaxially distributed inside the junction box and rotatably connected to the carriage, with the traction rope wound around it.

[0009] Optionally, one end of the retractor is rotatably connected to a push rod that extends through the junction box to its exterior.

[0010] Optionally, a conical locking block is fixedly connected to the other end of the winding rod, and a friction plate is adhered to the conical surface of the conical locking block; The junction box contains a conical sleeve that matches the conical locking block, and the inner side of the conical sleeve contains a friction sleeve that matches the friction plate.

[0011] Optionally, a locking rod is connected to the end of the strap away from the mounting rod, and a locking tube corresponding to the locking rod is fixed on the outer circumferential surface of the fixing box, and the locking rod can be inserted into the locking tube to form a locking engagement; One end of the clamping tube is threaded with a screw cap. The screw cap applies pressure to the clamping rod in the clamping tube, so that the clamping rod and the clamping tube are relatively fixed.

[0012] Optionally, a damper is fixedly installed between the junction box and the mounting bracket, and a second spring is fitted onto the damper.

[0013] (III) Beneficial Effects The beneficial effects of this utility model are: (1) During the initial branch pulling operation, by pushing the rack to drive the gear to rotate, the pawl can be deflected and disengaged from the ratchet, thereby releasing the lock on the installation rod; at this time, the binding strap can be pulled freely, wrapped around the branch, and the end of the clamp is inserted into the clamp tube and locked with the screw cap to form a loose and suitable initial binding ring. After the rack is released, the pawl automatically resets and meshes with the ratchet under the action of the torsion spring, so that the installation rod can only rotate in one direction, i.e., clockwise. In the subsequent tree growth process, the thickened branches will continue to push the binding strap outward. This force drives the installation rod to overcome the torque of the disc spring and rotate in the direction of the force, thereby slowly releasing the binding strap. This process realizes the adaptive adjustment of the binding ring diameter increasing synchronously with the growth of the branch, fundamentally avoiding the problems of phloem constriction, nutrient transport obstruction and even branch death caused by the inability to expand in the traditional fixed binding method, and providing a guarantee for the long-term healthy growth of fruit trees.

[0014] (2) By sliding the junction box and the mounting frame together and setting up a buffer mechanism consisting of a damper and a second spring, the branch puller can effectively buffer the impact force caused by wind or tree branch swaying, prevent the traction rope from suddenly breaking or causing mechanical damage to the branches, and improve the durability and safety of the equipment. In addition, the winding and releasing adjustment mechanism integrated in the junction box can conveniently and accurately control the winding and releasing of the traction rope by pushing the rod, thereby realizing stepless adjustment of the branch pulling angle and tension. This design eliminates the cumbersome steps of traditional knot fixing and can quickly adapt to the diverse needs of different fruit tree varieties, tree ages and shaping processes for the branch pulling angle, greatly improving the efficiency and quality of branch pulling operations.

Detailed Implementation

[0017] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0018] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0019] like Figures 1 to 7 As shown, this embodiment proposes a fruit tree branch puller, including: a mounting frame 1 for insertion and fixing to the ground; a junction box 2, in which a traction rope 3 is wound inside, and the bottom is slidably connected to the mounting frame 1; a fixing box 4, in which a mounting rod 6 is rotatably mounted, and a binding strap 7 is wound around the mounting rod 6; the traction rope 3 inside the junction box 2 is connected to the bottom of the fixing box 4; a clamping rod 17 is connected to one end of the binding strap 7 away from the mounting rod 6; a clamping tube 18 corresponding to the clamping rod 17 is fixed on the outer circumference of the fixing box 4; the clamping rod 17 can extend into the clamping tube 18 to form a clamping engagement; a screw cap 19 is threaded onto one end of the clamping tube 18; the screw cap 19 applies a compressive force to the clamping rod 17 in the clamping tube 18, so that the clamping rod 17 and the clamping tube 18 are relatively fixed.

[0020] In this embodiment, the mounting frame 1 serves as the fixed base for the entire branch puller, used to connect to the ground or low-lying tree trunks and provide stable support; the traction rope 3 inside the junction box 2 is connected to the fixing box 4, and the branch pulling angle and tension are adjusted by the extension and retraction adjustment mechanism 5 inside the junction box 2; the binding strap 7 inside the fixing box 4 is used to achieve adaptive binding of the branches.

[0021] In some embodiments, the retraction adjustment mechanism 5 includes: a slide 501 slidably installed in the junction box 2, a sleeve 503 fixedly installed between the slide 501 and the junction box 2, and a disc spring 504 fixedly sleeved on the sleeve 503; a winding rod 502, coaxially distributed in the junction box 2 and rotatably connected to the slide 501, a traction rope 3 wound on the winding rod 502, a push rod 505 rotatably connected to one end of the winding rod 502, the push rod 505 extending through the junction box 2 to its outside, and a conical block 506 fixedly connected to the other end of the winding rod 502, a friction plate 507 bonded to the conical surface of the conical block 506; a conical sleeve 509 adapted to the conical block 506 is formed in the junction box 2, and a friction sleeve 508 adapted to the friction plate 507 is provided on the inner side of the conical sleeve 509.

[0022] In this technical solution, by pushing the push rod 505 inward, the winding rod 502, which is rotatably connected to it, can be driven to slide within the junction box 2. The conical locking block 506 at the other end of the winding rod 502 separates from the conical sleeve 509, thereby releasing the friction locking state of the winding rod 502. At this time, the traction rope 3 can be freely pulled or wound back to adjust its length. When the desired length is reached, the push rod 505 is released, and the slide 501 pushes the winding rod 502 to reset under the reaction force of the disc spring 504, so that the friction plate 507 on the conical locking block 506 and the friction sleeve 508 inside the conical sleeve 509 are pressed together again. The huge frictional torque firmly locks the winding rod 502, fixing the length of the traction rope 3, thereby realizing the adjustment of the tension of the branch.

[0023] In some embodiments, the junction box 2 is slidably connected to the mounting bracket 1, such as... Figure 5 As shown, a damper 20 is fixedly installed between the junction box 2 and the mounting frame 1. A second spring 21 is fitted on the damper 20. The damper 20 and the second spring 21 of the mounting frame 1 and the junction box 2 form a buffer system, which can effectively absorb the impact of wind or tree branch swaying, protect the branches and the branch pulling structure, and jointly achieve the purpose of branch pulling that is both stable and adaptable to growth.

[0024] In some embodiments, both ends of the mounting rod 6 are fitted with disc springs 8, the inner and outer ends of the disc springs 8 being connected to the mounting rod 6 and the fixing box 4, respectively; a ratchet 9 is fitted onto the mounting rod 6, and a pawl 10 that meshes with the ratchet 9 is rotatably mounted inside the fixing box 4, the pawl 10 being rotatably connected to the fixing box 4 via a rotating rod 11; a torsion spring 12 is fitted onto the rotating rod 11, the two ends of the torsion spring 12 being fixedly connected to the pawl 10 and the fixing box 4, respectively; the ratchet 9 and the pawl 10 cooperate to allow the mounting rod 6 to extend along the released strap 7. The direction of rotation is prevented from reversing. In the initial state, the pawl 10 engages with the ratchet 9 under the action of the torsion spring 12, preventing the mounting rod 6 from reversing to tighten the binding strap 7, but allowing it to rotate clockwise to release the binding strap 7. The disc spring 8 continuously provides the pre-tightening force that causes the mounting rod 6 to reverse and tighten the binding strap 7. When the branch grows thicker, it will push the binding strap 7 outward and drive the mounting rod 6 to overcome the pre-tightening force of the disc spring 8 and rotate clockwise, slowly releasing the binding strap 7, thereby realizing the automatic expansion of the binding ring and avoiding damage to the branch.

[0025] refer to Figure 2 , Figure 3 , Figure 4 As shown, a gear 13 is also sleeved on the rotating rod 11. A rack 14 that meshes with the gear 13 is slidably installed in the fixed box 4. A slide rod 15 that guides the rack 14 is fixedly installed in the fixed box 4. The rack 14 is slidably sleeved on the slide rod 15. Two sets of symmetrically distributed first springs 16 are sleeved on the slide rod 15. The two ends of the two sets of first springs 16 are fixedly connected to the rack 14 and the fixed box 4, respectively.

[0026] In this technical solution, the rack 14 is pushed to compress the first spring 16. The rack 14 drives the gear 13 and drives the rotating rod 11 to rotate, causing the pawl 10 to deflect against the force of the torsion spring 12, thereby disengaging from the ratchet 9 and releasing the lock on the mounting rod 6. At this time, the strap 7 can be pulled out freely, and the locking rod 17 can be inserted into the locking tube 18 and the screw cap 19 can be tightened to form a closed loop around the branch. After the rack 14 is released, under the combined action of the first spring 16 and the torsion spring 12, the pawl 10 quickly resets and re-engages with the ratchet 9, restoring the unidirectional rotation function.

[0027] Working principle: During initial branch pulling, the rack 14 is pushed to rotate the gear 13, causing the pawl 10 to deflect and disengage from the ratchet 9, thereby releasing the lock on the mounting rod 6. The operator then pulls the binding strap 7, wraps it around the branch to be pulled, and inserts the locking rod 17 at the end of the binding strap 7 into the locking tube 18 on the fixing box 4 and locks it with the screw cap 19. The binding strap 7 forms a binding ring to bind the branch. After binding is completed, the rack 14 is released, and the pawl 10, under the action of the torsion spring 12, automatically... The mechanism resets and re-engages with the ratchet 9. At this time, under the one-way limiting action of the ratchet 9 pawl 10, the mounting rod 6 can only rotate clockwise, i.e., in the direction of releasing the strap 7. Then, the push rod 505 is pushed inward, driving the connected winding rod 502 to move. The conical locking block 506 at the other end of the winding rod 502 separates from the conical sleeve 509, releasing the friction locking state of the winding rod 502. At this time, the traction rope 3 can be freely pulled or wound back for length adjustment. After adjusting to the required length, release the push rod 505. Under the reaction force of the disc spring 504, the slide 501 pushes the winding rod 502 back to its original position. The friction plate 507 on the conical block 506 and the friction sleeve 508 inside the conical sleeve 509 are pressed together again. The huge frictional torque locks the winding rod 502 firmly, fixing the length of the traction rope 3. Finally, the mounting frame 1 is fixed to the ground or a low position on the tree trunk. During subsequent growth, as the branches gradually thicken, they will spread the binding strap 7 outward. This force drives the mounting rod 6 to overcome the torque of the disc spring 8 and rotate clockwise, slowly releasing more binding strap 7. This achieves adaptive adjustment so that the diameter of the binding ring increases synchronously with the growth of the branches, effectively preventing strangulation.
