Description

Technical Field

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

[0002] During the fruit tree planting process, due to the plant's phototropism and some external factors, some branches may bend at a specific angle. This has a significant impact on the final development and fruit-bearing capacity of the fruit tree. In particular, for some relatively large fruit trees, the cost and difficulty of replanting are greater. Therefore, fruit farmers usually correct these fruit trees.

[0003] Traditional straightening methods involve binding a vertical stick to the branch with straps, allowing the branch to grow and straighten along the axis of the stick. However, in practice, for fruit trees with poor branch flexibility, if the curvature is large, straightening it all at once can easily cause the branch to break. Multiple straightenings are very troublesome and require multiple adjustments within the straightening cycle. Therefore, a fruit tree branch growth straightening device is specially provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fruit tree branch growth correction device, which solves the problem that for some fruit trees with poor branch toughness, if the curvature is large, direct straightening at once can easily cause the branch to break, and multiple corrections are very troublesome, requiring multiple adjustments within the correction cycle.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fruit tree branch growth correction device, comprising two mutually hinged fixing units, the two sets of fixing units being used to fix the two ends of the bent part of the branch, and an adjustable elastic correction component being installed between the two sets of fixing units;

[0006] The adjustable elastic straightening component includes a sleeve and a top shaft that is movably inserted into one end of the sleeve. A straightening spring is provided inside the sleeve. Sliding seats are movably hinged to the opposite ends of the sleeve and the top shaft. The two sets of sliding seats are slidably arranged on two sets of fixed units. The compression of the straightening spring is adjusted by changing the distance between the two sets of sliding seats, thereby changing the straightening force on the bent part of the branch.

[0007] Preferably, the fixing unit includes two sets of adhesive strips, with hinges installed at opposite ends of the two sets of adhesive strips, and binding members for fixing to the tree branches installed at opposite ends of the two sets of adhesive strips.

[0008] Preferably, the binding member includes a semi-circular clamping part integrally formed on the outer end of the bonding strip; and a binding strap installed on the semi-circular clamping part, wherein both the semi-circular clamping part and the outer surface of the bonding strip are provided with arc-shaped grooves.

[0009] Preferably, one end of the binding strap is fixed to one side of the semi-circular clamping part, and a fixing hole is provided on the other side of the semi-circular clamping part. A hook is installed on the side of the semi-circular clamping part away from the fixing hole. The outer wall of the binding strap is provided with equidistant hanging holes. The binding strap passes through the fixing hole and folds back to engage with the hook through the hanging hole.

[0010] Preferably, the bottom of the bonding strip is provided with a groove, and the sliding seat is slidably connected in the groove.

[0011] Preferably, an adjusting screw is rotatably connected in the groove, the sliding seat is threadedly connected to the adjusting screw, and the outer end of the adjusting screw is integrally formed with an external hexagonal knob.

[0012] This utility model discloses a fruit tree branch growth correction device, which has the following beneficial effects: By binding two bonding strips to the two ends of the bent part of the fruit tree branch with the binding parts at their outer ends, rotating the adjusting screw causes the two sets of sliding seats to move towards the center along the sliding groove, compressing the correction spring. Under the elastic force of the correction spring, the two sets of bonding strips tend to flip to the other side. The compression amount of the correction spring is adjusted according to the thickness of the branch, so that the branch has a growth correction trend opposite to the bending direction during the subsequent growth period under the action of the correction spring, thereby assisting the branch to be corrected in the long term, avoiding the branch breakage caused by one-time straightening, and also eliminating the need for multiple adjustments during the correction cycle.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This application provides a fruit tree branch growth correction device, which solves the problem that for some fruit trees with poor branch toughness, if the curvature is large, it is easy to break the branch if it is straightened directly in one go, and multiple corrections are very troublesome and require multiple adjustments within the correction cycle.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a fruit tree branch growth correction device.

[0023] Example 1

[0024] According to the appendix Figure 1-4 As shown, it includes two hinged fixing units 1, which are used to fix the two ends of the bent part of the branch respectively. An adjustable elastic correction element 2 is installed between the two fixing units 1.

[0025] The adjustable elastic straightener 2 includes a sleeve 21 and a top shaft 22 that is movably inserted into one end of the sleeve 21. A straightening spring 23 is provided inside the sleeve 21. Sliding seats 24 are movably hinged to the opposite ends of the sleeve 21 and the top shaft 22. The two sets of sliding seats 24 are slidably arranged on the two sets of fixed units 1. The compression of the straightening spring 23 is adjusted by changing the distance between the two sets of sliding seats 24, thereby changing the straightening force on the bent part of the branch.

[0026] The fixing unit 1 includes two sets of adhesive strips 11. A hinge 3 is installed at one end of the two sets of adhesive strips 11 facing each other, and a binding piece for fixing the tree branch is installed at the opposite end of the two sets of adhesive strips 11.

[0027] The bottom of the bonding strip 11 is provided with a groove 12, and the sliding seat 24 is slidably connected in the groove 12.

[0028] An adjusting screw 25 is rotatably connected in the slide groove 12. The sliding seat 24 is threadedly connected to the adjusting screw 25. The outer end of the adjusting screw 25 is integrally formed with an external hexagonal knob 26. By rotating the adjusting screw 25, the distance between the two sets of sliding seats 24 is changed, thereby changing the compression of the straightening spring 23. During the straightening process, as the branches are continuously straightened, the straightening spring 23 gradually extends. When the bent part of the branch is completely straightened, the sleeve 21 and the top shaft 22 are just parallel to the two sets of bonding strips 11. At this time, since the sleeve 21 and the top shaft 22 are movably inserted, the two sets of bonding strips 11 cannot continue to rotate, thus avoiding over-straightening.

[0029] Working principle: When using this device, the two bonding strips 11 are tied to the two ends of the bent part of the fruit tree branch using the binding parts at their outer ends. Then, the external hexagonal knob 26 is rotated directly or by wrench, causing the adjusting screw 25 to rotate. This causes the two sets of sliding seats 24 to move towards the center along the sliding groove 12, shortening the distance between the opposite ends of the sleeve 21 and the top shaft 22, thereby compressing the straightening spring 23. At this time, under the elastic force of the straightening spring 23, the two sets of bonding strips 11 tend to flip to the other side. The compression of the straightening spring 23 can be adjusted according to the thickness of the branch, so that the branch will always have a growth trend opposite to the bending direction under the action of the straightening spring 23 in the subsequent growth period. This helps the branch to be straightened for a long time, avoiding the breakage of the branch due to one-time straightening, and also eliminating the need for multiple adjustments during the straightening cycle.

[0030] Example 2

[0031] According to the appendix Figure 1-4 As shown, based on Embodiment 1, more specifically, the binding member includes a semi-circular clamping part 13 integrally formed on the outer end of the bonding strip 11; and a binding strap 14 installed on the semi-circular clamping part 13. Both the semi-circular clamping part 13 and the outer surface of the bonding strip 11 are provided with arc-shaped grooves 18.

[0032] One end of the binding strap 14 is fixed to one side of the semi-circular clamping part 13. A fixing hole 15 is provided on the other side of the semi-circular clamping part 13. A hook 16 is installed on the side of the semi-circular clamping part 13 away from the fixing hole 15. The outer wall of the binding strap 14 is provided with equidistant hanging holes 17. The binding strap 14 passes through the fixing hole 15 and folds back to engage with the hook 16 through the hanging hole 17.

[0033] Working principle: When binding the branch, the arc-shaped groove 18 is placed against the lower surface of the branch in the bending direction. Then, the binding strap 14 is wrapped around the upper surface of the branch. After passing through the fixing hole 15, the binding strap 14 is suspended and fixed by the hook 16 through the hanging hole 17. At this time, the arc-shaped groove 18 makes pressure contact with the surface of the branch. Compared with the traditional binding stick, the traditional stick provides support, while the binding strap has a reverse bending and pulling effect on the branch. Therefore, the branch is easily pulled by the binding strap, which can cause damage to the bark. The fixing method of this device can effectively avoid the bark injury of the branch during the correction process.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
