Description

Technical Field

[0001] This utility model relates to the field of branch pulling tools, and in particular to a branch pulling device for pepper trees. Background Technology

[0002] In the cultivation of Sichuan pepper, branch training is an important and often reworked step. The key research focuses on the effectiveness of branch training in shaping the tree and the degree of damage to the branches and trunk. These two factors directly affect the quality and yield of the fruit, thus impacting economic benefits.

[0003] Currently, the following methods are mainly used for fruit tree branch training both domestically and internationally: First, branch training is achieved by using ropes and suspended weights or by using ropes and wooden poles fixed to the ground. This method is time-consuming and labor-intensive, and the pulling force is not easy to control. Second, branch training is achieved by using a single branch training device, that is, one branch training device is needed for each branch. This type of branch training device has a simple structure and is easy to operate, but the pulling force is not easy to control and it is easy to damage the trunk and branches.

[0004] Chinese patent application number 202320896221.6 discloses a simple tool for pulling branches of Sichuan pepper trees, comprising a main body in the shape of a rod. A movable rod is slidably disposed inside one end of the main body, and two connecting rods are fixedly connected to the outer circumference of the main body. These two connecting rods are symmetrically arranged, and each connecting rod has a positioning hook at its end away from the movable rod. While this patent facilitates the adjustment of the pulling force, its structure is relatively complex, resulting in high production costs and inconvenient processing. Utility Model Content

[0005] This utility model proposes a branch-pulling device for pepper trees to solve the above-mentioned problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A branch-pulling device for Sichuan pepper trees includes an outer ring, inside which a threaded rod is fixed by a threaded connection. Two pulling rods are symmetrically fixed on the outer wall of the outer ring. One end of each threaded rod has an integrally formed fixing head. An upper rotating seat is rotatably mounted on the fixing head. Two fixing plates are fixed on the side of the upper rotating seat away from the fixing head. A roller is detachably connected and fixed between the two fixing plates by fixing bolts. The roller is rotatably fitted with the fixing bolts. A V-groove is formed on the outer circumference of the roller.

[0008] Furthermore, a limiting disc is integrally formed at the end of the fixing head that is away from the upper rotating seat, and the fixing head and the upper rotating seat are fixed together by bearings.

[0009] Further, the end of the threaded rod away from the fixed head is fixed with a protective handle, and the surface of the protective handle is formed with anti-skid lines.

[0010] Further, the pulling rod comprises a connecting part fixed with the sleeve ring and a pulling part for pulling branches, and the pulling part is fixed at the end away from the connecting part.

[0011] Further, the pulling part is any one of a hook or a steel wire roller.

[0012] By adopting the above technical scheme, the utility model has the advantages of simple overall structure, threaded connection and fixation of the sleeve ring and the threaded rod, direct composition of the pulling rod by the connecting part and the pulling part, convenient production, low cost, quick assembly and use, detachable roller, convenient replacement, free rotation of the upper rotating seat of the fixed roller relative to the threaded rod, and avoidance of twisted broken pepper branches during branch pulling operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, a branch-pulling device for Sichuan pepper trees includes an outer ring 1. A threaded rod 3 is fixed inside the outer ring 1 via a threaded connection. The threaded rod 3 is made of hard plastic, which is lightweight, strong, and low-cost. The threaded connection facilitates quick adjustment of the relative position and assembly / disassembly. Two pull rods 2 are symmetrically fixed on the outer wall of the outer ring 1. The pull rods 2 can be used to fix the Sichuan pepper branches and facilitate determining the bending position of the branches. One end of the threaded rod 3 has a fixed head 5 integrally formed. An upper rotating seat 7 is rotatably installed on the fixed head 5. Two fixed upright plates 8 are fixed on the side of the upper rotating seat 7 away from the fixed head 5. A roller 10 is detachably connected and fixed between the two fixed upright plates 8 via a fixing bolt 9. The roller 10 is rotatably fitted with the fixing bolt 9. A V-shaped groove is formed on the outer circumference of the roller 10 to facilitate clamping the Sichuan pepper branches. The rotatable fit between the fixed head 5 and the upper rotating seat 7 can prevent the upper rotating seat 7 from rotating and breaking the Sichuan pepper branches when the threaded rod 3 rotates.

[0023] In this embodiment, the end of the fixing head 5 that is close to and away from the upper rotating seat 7 is integrally formed with a limiting disk 4, which is used to limit the position of the upper rotating seat 7. The fixing head 5 and the upper rotating seat 7 are fixed together by a bearing 6 to reduce the friction at the contact point, reduce the lateral torque on the pepper branches, and protect the pepper branches.

[0024] In this embodiment, a protective handle 11 is fixed to the end of the threaded rod 3 away from the fixed head 5. The protective handle 11 is made of rubber and is directly fitted onto the end of the threaded rod 3 without being able to rotate relative to it. The surface of the protective handle 11 is formed with anti-slip texture to increase friction and facilitate operation.

[0025] In this embodiment, the pull rod 2 includes a connecting part 21 fixed together with the outer ring 1 and a pulling part 22 for pulling branches. The pulling part 22 is fixed at the end away from the connecting part 21. The pulling part 22 can be either a hook or a wire roller 10. The hook structure is easy to manufacture, but it is easy to slide and rub against the pepper branches during use, which can easily scratch the branches. The wire roller 10 adopts a rotating connection and is fixed together with the connecting part 21. It can roll and slide after contacting the branches, avoiding damage to the pepper branches during use.

[0026] The working principle of the utility model is as follows: when in use, the two pull rods 2 are hooked on the branches of the Chinese prickly ash, then one hand holds one of the pull rods 2 to avoid its twisting, the other hand twists the protective handle 11 to drive the threaded inserting rod 3 to rotate, the threaded inserting rod 3 drives the roller 10 to move to the branches after rotating and bends the branches, the amplitude of the bending of the branches can be adjusted by twisting the threaded inserting rod 3.

[0027] Components not described in detail herein are of the prior art.

[0028] The above merely describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
