Description

Technical Field

[0001] This utility model relates to the field of agricultural production auxiliary equipment technology, and more specifically to a branch pulling device for young fruit trees. Background Technology

[0002] The purpose of branch training in fruit trees is to expand the canopy, accelerate tree formation, improve ventilation and light penetration, regulate the types of endogenous hormones and the transport and distribution of nutrients, adjust tree vigor, promote flowering, make full use of space, and achieve three-dimensional fruiting. Under natural growth conditions, fruit trees develop their canopies slowly, and the trunk and branches are not widely spread, resulting in a closed canopy, poor ventilation and light penetration within the tree, and the fruiting parts shifting outwards. This affects the tree's photosynthesis and overall health, ultimately leading to reduced fruit yield and quality.

[0003] Therefore, to ensure the vegetative and reproductive growth of fruit trees and achieve the goals of rapid shaping, early flowering, and early fruiting, some artificial intervention is needed in the angle and direction of branching during the growth process. However, currently, most fruit tree branch pulling methods use ropes, support sticks, and branch pulling devices, which are inconvenient to operate and can cause damage to branches during implementation.

[0004] Therefore, in view of the existing problems, how to provide a branch pulling device for young fruit trees that can effectively reduce tree damage through flexible binding components and buffer design, while improving the convenience and adaptability of branch pulling operations, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides a branch pulling device for young fruit trees, which can effectively reduce tree damage through flexible binding components and buffer design, while improving the convenience and adaptability of branch pulling operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A branch-pulling device for young fruit trees includes: a retaining ring, a mounting plate, a tie rod, and a binding assembly;

[0008] The number of mounting plates is multiple, and they are slidably connected to the outer side wall of the retaining ring respectively;

[0009] The number of the pull rods corresponds to the number of the mounting plates. One end of each pull rod is hinged to the mounting plate, and the other end is hinged to a fixing ring. The fixing ring has an opening for branches to enter.

[0010] The number of binding components corresponds to the number of pull rods. Each binding component includes a binding rope and a winding device. One end of the binding rope is fixed to the inner side wall of the fixing ring and extends circumferentially to the outer side wall of the fixing ring. The winding device is mounted on the mounting plate, and the other end of the binding rope is wound around the winding device to realize the winding and unwinding of the binding rope.

[0011] Through the above technical solution, this utility model provides a branch-pulling device for young fruit trees. A retaining ring is used to fix the branch to the trunk. A mounting plate is slidably connected to the outer wall of the retaining ring. One end of the pull rod is hinged to the mounting plate, and the other end is hinged to a fixing ring. The binding assembly includes a binding rope and a winding device. One end of the binding rope is fixed to the inner wall of the fixing ring, and the other end is wound around the winding device to achieve the release and retraction of the binding rope. This technical solution solves the problem of branch-pulling in fruit trees by using a retaining ring fixing device, adjusting the length and direction of the pull rod, and fixing the branches with the binding assembly.

[0012] Preferably, in the above-mentioned branch-pulling device for young fruit trees, the retaining ring includes two arc-shaped plates that form a ring. One end of the two arc-shaped plates is hinged, and the other end is engaged. A groove is formed on the outer wall of each arc-shaped plate. The mounting plate is slidably connected within the groove, and the surface of the mounting plate is parallel to the central axis of the arc-shaped plate. This design allows the retaining ring to be disassembled, facilitating size adjustment to fit different trunk thicknesses. Simultaneously, the cooperation between the groove and the mounting plate allows the mounting plate to slide freely on the retaining ring, ensuring the stability of the branch-pulling direction.

[0013] Preferably, in the above-mentioned branch-pulling device for young fruit trees, the pull rod includes a first connecting rod, a second connecting rod, and a sleeve. One end of the first connecting rod is hinged to the mounting plate, and the other end has a first thread. The end of the second connecting rod away from the first connecting rod is hinged to the fixing ring, and the end closer to the first connecting rod has a second thread. The inner wall of the sleeve has a third thread, which is threadedly connected to the first thread and the second thread. By rotating the sleeve, the length of the pull rod can be adjusted, realizing flexible adjustment of the branch-pulling length.

[0014] Preferably, in the above-mentioned branch-pulling device for young fruit trees, the fixing ring includes a traction fixing plate and a traction movable plate. The traction fixing plate is fixed to the end of the second connecting rod away from the first connecting rod and has the opening thereon. The traction movable plate corresponds to the opening, with one end rotatably connected to the traction fixing plate and the other end abutting against the traction fixing plate to seal the opening. One end of the binding rope is fixed to the inner sidewall of the traction fixing plate and extends along the inner sidewall to the outer sidewall of the traction fixing plate. This design facilitates quick insertion or removal of branches, while the binding rope evenly distributes the tension, preventing localized pressure on the branches.

[0015] Preferably, in the above-mentioned branch-pulling device for young fruit trees, the winding component includes a drive rod, a winding wheel, a positioning disc, a handwheel, and a fixing pin. The drive rod passes through the surface of the mounting plate and is rotatably connected to the mounting plate; the winding wheel is fixed to one end of the drive rod, and the other end of the binding rope is fixed to the winding wheel; the positioning disc is located at the other end of the drive rod, and a positioning hole is provided on the positioning disc; the handwheel is located at the end of the positioning disc away from the winding wheel and is rotatably connected to the drive rod; the fixing pin movably passes through the handwheel and can be engaged with the positioning hole. The positioning disc is located at the end of the handwheel away from the winding wheel, rotatably connected to the drive rod, and has a positioning hole. The fixing pin movably passes through the fixing pin and can be engaged with the positioning hole. By rotating the handwheel to wind and unwind the binding rope, when the rope reaches a suitable length, the fixing pin locks in place, achieving the effect of eliminating the need for repeated manual tightening of the rope.

[0016] Preferably, the above-mentioned branch-pulling device for young fruit trees further includes a buffer assembly, which comprises a moving rod, a buffer spring, and a buffer plate. Each arc-shaped plate has a sliding groove on its inner sidewall. There are multiple moving rods arranged in two groups, with one end of each group's moving rod slidably connected to the sliding groove. The buffer spring is located within the sliding groove, and its two ends are fixedly connected to the moving rod. There are two buffer plates, each hinged to the other end of a moving rod. This effectively absorbs the impact force generated during branch pulling, reducing damage to the tree and improving the safety and stability of the branch pulling process.

[0017] Preferably, the above-mentioned young fruit tree branch-pulling device further includes a fastening pin. The bottom wall of the sliding groove has multiple first through holes, and the mounting plate has a second through hole. The fastening pin can pass through both the first and second through holes to position the mounting plate. This positioning of the mounting plate ensures its stability during branch-pulling. Furthermore, the fastening pin design facilitates quick positioning and fixing of the mounting plate, improving work efficiency.

[0018] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a branch-pulling device for young fruit trees, which has the following beneficial effects:

[0033] In some specific examples, the retaining ring 1 includes two arc-shaped plates 11, which are arranged in a ring shape. One end is hinged and the other end is snapped together. Slide grooves 111 are provided on the outer side walls of both arc-shaped plates 11.

[0035] In a specific embodiment, the fixing ring 4 includes a traction fixing plate 41 and a traction movable plate 42. The traction fixing plate 41 is fixed to the end of the second connecting rod 32 away from the first connecting rod 31 and has an opening. The traction movable plate 42 corresponds to the opening, and one end of it is rotatably connected to the traction fixing plate 41, while the other end abuts against the traction fixing plate 41 to seal the opening. One end of the binding rope 51 is fixed to the inner sidewall of the traction fixing plate 41 and extends along the inner sidewall of the traction fixing plate 41 to the outer sidewall of the traction fixing plate 41.

[0036] In a specific example, the winding assembly 52 includes a drive rod 521, a winding reel 522, a positioning disc 523, a handwheel 524, and a fixing pin 525. The drive rod 521 passes through the surface of the mounting plate 2 and is rotatably connected to the mounting plate 2; the winding reel 522 is fixed to one end of the drive rod 521, and the other end of the binding rope 51 is fixed to the winding reel 522; the positioning disc 523 is located at the other end of the drive rod 521, and a positioning hole 5231 is provided on the positioning disc 523; the handwheel 524 is located at the end of the positioning disc 523 away from the winding reel 522 and is rotatably connected to the drive rod 521; the fixing pin 525 movably passes through the handwheel 524 and can be engaged with the positioning hole 5231.

[0037] In some examples, a buffer assembly 6 is also included, which includes a moving rod 61, a buffer spring 62, and a buffer plate 63. Each arc-shaped plate 11 has a sliding groove 112 on its inner sidewall. There are multiple moving rods 61, which are divided into two groups. One end of each group of moving rods 61 is slidably connected in the sliding groove 112. The buffer spring 62 is located in the sliding groove 112, and its two ends are fixedly connected to the moving rods 61 respectively. There are two buffer plates 63, and each buffer plate 63 is hinged to the other end of the moving rod 61.

[0038] In a specific embodiment, a fastening pin is also included. The bottom wall of the slide groove 111 has multiple first through holes, and the mounting plate 2 has a second through hole. The fastening pin can pass through the first through hole and the second through hole to achieve the positioning of the mounting plate 2.

[0039] The method of use and working principle of this utility model are as follows:

[0040] First, open the two arc-shaped plates 11 of the retaining ring 1 and wrap it around the trunk of the young fruit tree, so that the hinged ends of the two arc-shaped plates 11 rotate and close, and the other end is fixed by the snap-fit ​​structure, completing the initial installation of the retaining ring 1 on the trunk. At this time, the buffer component 6 inside the retaining ring 1 will automatically adapt to the thickness of the trunk, the buffer plate contacts the trunk, the moving rod 61 adjusts its position in the sliding groove 112, and the buffer spring 62 is in a natural extension and contraction state, preparing for the impact buffer during the subsequent branch pulling process. Depending on the number and position of the branches to be pulled, the mounting plate is slidably connected in the sliding groove 111 of the arc-shaped plate 11. Since the surface of the mounting plate 2 is parallel to the central axis of the arc-shaped plate 11, the stability of the subsequent pulling rod 3 can be ensured during the sliding process. When the mounting plate 2 slides to the appropriate position, the fastening pin passes through the first through hole in the bottom wall of the sliding groove 111 and the second through hole on the mounting plate 2 to realize the positioning of the mounting plate 2 and prevent the mounting plate 2 from shifting during the branch pulling process. The sleeve 33 in the rotating pull rod 3 has a third thread on its inner wall that is threadedly connected to the first thread 311 of the first connecting rod 31 and the second thread 321 of the second connecting rod 32. Rotating the sleeve 33 can change the insertion length of the first connecting rod 31 and the second connecting rod 32 within the sleeve 33, thereby adjusting the total length of the entire pull rod 3 to fit the distance from the tree trunk to the branch to be pulled. Open the end of the traction movable plate 42 in the fixing ring 4 that abuts against the traction fixing plate 41. Place the branch to be pulled into the traction fixing plate 41 through the opening on the fixing ring 4. Then rotate the traction movable plate 42 so that its other end abuts against the traction fixing plate 41 again, sealing the opening and initially fixing the branch. Rotate the handwheel 524 of the winding component 52. The handwheel 524 drives the drive rod 521 to rotate, and the winding wheel 522 at one end of the drive rod 521 rotates accordingly, starting to wind the binding rope 51. One end of the binding rope 51 is fixed to the inner wall of the traction fixing plate 41. As the winding wheel 522 winds around, the binding rope 51 gradually tightens, further securing the branch. When the binding rope 51 is tightened to a suitable degree and can stably hold the branch, the fixing pin 525 is moved through the handwheel and engaged with the positioning hole 5231 on the positioning plate 523, locking the position of the winding wheel 522 and preventing the binding rope 51 from loosening, thus completing the branch fixation. Since one end of the pull rod 3 is hinged to the mounting plate 2 and the other end is hinged to the fixing ring 4, the branch pulling angle can be adjusted by rotating the pull rod 3 and the fixing ring 4 to achieve the ideal growth direction. During the growth of the fruit tree, if the branch growth causes the binding rope 51 to become too tight, the fixing pin 525 can be pulled out, the handwheel 524 can be rotated in the opposite direction to loosen the binding rope 51, and after adjusting to a suitable tightness, it can be locked again with the fixing pin 525 to avoid affecting the normal growth of the branch.
