Description

Branch pulling device for shaping branches of fruit trees

Technical Field

The utility model relates to a branch puller, especially a branch puller is used in plastic of fruit tree branch belongs to the fruit tree and cultivates the field.

Background

If any branch grows freely in the fruit tree cultivation process, the branches on the sunny side grow too densely due to the positive of the plants, so that the sunlight is shielded, the illumination rate is reduced, the ventilation is not facilitated, and the yield and the quality of the fruits are reduced. Therefore, when the branches are still soft in the early growth stage of the fruit trees, the branch pulling device is usually used for pulling and opening the branches, namely the branch pulling device is used for limiting the growth and bending directions of the branches, so that the branches can grow according to the will of people, and the branch shaping effect is achieved.

The existing branch puller is generally divided into two forms, namely a Chinese utility model patent with the similar authorization publication number of CN204540057U, when in use, a fixing ring is required to be sleeved and fixed on a trunk, and the branch is pulled down and bent by a hook connected with the branch through a pull rope by taking the fixing ring as a stress point; another similar patent with the publication number of CN208175576U, which is a chinese utility model, is hung on the branch by a hook with a weight to make the branch droop. However, the two forms of the branch pulling devices have the major defects that the fixed ring on the trunk is pulled upwards by the reaction force of the branches, and the trunk is tied and scratched by the existence of the fixed ring, so that the trunk epidermis is damaged. The branch puller in the latter form has poor stability, and particularly, the swinging degree of the branches is increased by heavy objects hung in windy weather, so that the problems of breakage and the like are easily caused.

Therefore, there is a need for a branch puller that can avoid the above-mentioned disadvantages of the two prior art forms.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

The first embodiment is as follows: as shown in figures 1-2, the utility model discloses a branch-pulling device for shaping fruit tree branches, which comprises a supporting angle iron 1, a nut 2, a tension bolt 3, a hook 4, two wheel shafts 5 and two rollers 6, wherein the supporting angle iron 1 has a downward opening and an included angle integrally provided with a flat plate connecting part 1-1, the nut 2 is welded and fixed at the central position of the upper surface of the flat plate connecting part 1-1, the flat plate connecting part 1-1 is provided with a through hole which is penetrated through by the nut 2, the tension bolt 3 is screwed and matched with the nut 2, the lower end of the tension bolt 3 is integrally provided with a cylindrical joint 3-1, the connecting end of the hook 4 is integrally provided with a clamping groove 4-1 which is rotatably matched with the cylindrical joint 3-1 and is rotatably connected at the lower end of the tension bolt 3 through the clamping groove 4-1, the middle positions of the end parts of the support arms at both sides of, the two wheel shafts 5 are respectively fixed at the middle positions in the two notches 1-2, the two rollers 6 are respectively rotatably installed on the two wheel shafts 5, and the end parts of the support arms at the two sides of the support angle iron 1 are respectively bent towards the inner side of the support angle iron 1 to form anti-falling chucks 1-3.

The second embodiment is as follows: as shown in fig. 1 to 2, in the present embodiment, the circumferential surface of the roller 6 is a concave arc surface.

The third concrete implementation mode: as shown in fig. 1 to 2, in the present embodiment, a pull ring 3-2 is fixedly provided at an upper end of the tightening bolt 3, which is described further with respect to the first embodiment or the second embodiment.

The fourth concrete implementation mode: as shown in fig. 1 to 2, in this embodiment, a third embodiment is further described, and the included angle between the support arms on both sides of the support angle 1 is 60 ° to 120 °.

The fifth concrete implementation mode: as shown in fig. 1 to 2, in the present embodiment, a fourth embodiment is further described, and the anti-drop chuck 1-3 is provided perpendicular to one side arm corresponding to the support angle 1.

Referring to fig. 1-2, when the utility model is used to draw and angle the branches of fruit trees, two rollers 6 rotatably mounted on the support arms at both sides of the support angle 1 are attached to the positions of the branches of fruit trees to be bent, and simultaneously the hook 4 is passed through the middle of the branches of fruit trees, the bending direction of the branches of fruit trees is adjusted by adjusting the opening direction of the support angle 1, the bending direction of the branches of fruit trees is consistent with the opening direction of the support angle 1, then the hook 4 is moved to the included angle position of the support angle 1 by rotating the tension bolt 3-2 through the pull ring 3-2, the hook 4 is rotatably connected to the cylindrical joint 3-1 at the lower end of the tension bolt 3 through the slot 4-1, therefore, the hook 4 does not rotate with the tension bolt 3, only pulls the middle of the branches of fruit trees to move to the included angle position of the support angle 1, and the two rollers 6 support the branches of fruit trees, therefore, the fruit tree branches are bent, meanwhile, the rollers 6 rotate to avoid scraping the fruit tree branches, and the anti-falling chucks 1-3 can limit the fruit tree branches and avoid being separated from the rollers 6.
