Description

Technical Field

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

[0002] As the fruit grows, the weight of the fruit tree gradually increases. Too many fruits on a branch can bend or even break the branch. In order to ensure the normal growth of the fruit and meet the yield requirements, it is necessary to pull the branches of the fruit tree.

[0003] For mature trees, existing branch-pulling methods mostly involve driving stakes into the ground next to the fruit tree, then installing a shaping frame, and tying the fruit tree branches to the frame with ropes for pulling. Most of the shaping frames are fixed, which means that the frame structure cannot be height adjusted. As the fruit tree grows and develops, the shaping frame cannot adapt to different branch-pulling processes, requiring repeated disassembly and replacement of the shaping frame, which is quite troublesome and increases the labor intensity of the workers. Some existing branch-pulling devices use umbrella-shaped or inverted umbrella-shaped structures to provide pulling or supporting force, but they all have the problem of inconvenient adjustment of the branch-pulling strength. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fruit tree branch puller, which aims to solve the problems of low efficiency of using rope binding, insufficient flexibility of fixed shaping frame, and inconvenience of adjusting the branch pulling intensity of existing branch pullers.

[0005] The objective of this utility model is achieved through the following technical solution: A fruit tree branch puller includes a hand-cranked telescopic hook, a collar, a fixing ring, and a post. The fixing ring is fixed to the lower end of the post and sleeved on the tree trunk. The fixing ring is provided with a positioning component for fixing the fixing ring to the tree trunk. The collar is detachably sleeved on the upper end of the post. The hand-cranked telescopic hook includes a hand-cranked winding mechanism and a steel wire rope. The hand-cranked winding mechanism is fixed to the collar and is used to wind up and unwind the steel wire rope. The end of the steel wire rope is provided with a hook.

[0006] Furthermore, the collar is formed by the engagement of a first semicircular ring and a second semicircular ring. The first semicircular ring and the second semicircular ring are respectively provided with a groove and a buckle on opposite sides, and the first semicircular ring and the second semicircular ring are fastened together by the groove and the buckle.

[0007] Furthermore, the fixing ring is formed by two semi-circular fixing plates that hug each other, and the ends of the two fixing plates are connected by fixing bolts. The outer side of one fixing plate is fixedly connected to the lower end of the column.

[0008] Furthermore, the positioning assembly includes an adjusting bolt and an arc-shaped positioning ring. There are two positioning rings arranged opposite each other. The outer side of the positioning ring is provided with a positioning sleeve corresponding to the adjusting bolt. The adjusting bolt is threadedly connected to the fixing plate and rotatably connected to the corresponding positioning sleeve.

[0009] Furthermore, the hand-cranked telescopic hook includes a housing, a crank handle, a hexagonal drive shaft, a rotating sleeve, a reel, a spring, and a friction sleeve. The housing is fixed on a collar, and the rotating sleeve is rotatably disposed inside the housing. The crank handle is provided with a hexagonal drive shaft, which is inserted into the housing and engaged with one end of the rotating sleeve. The rotating sleeve has an inner ring at the end opposite to the hexagonal drive shaft, and the inner ring has an opening. The ends of the inner ring located on both sides of the opening are bent toward the center of the rotating sleeve. The spring is sleeved on the inner ring, and the two ends of the spring are bent toward the center of the rotating sleeve and respectively abut against the bent portions of the inner ring located on both sides of the opening. The reel is movably sleeved on the rotating sleeve between the inner wall of the housing and the inner ring. The side wall of the reel has a protrusion, which is inserted between the spring and the inner ring along the opening of the inner ring. One end of the wire rope is wound on the reel, and the other end of the wire rope passes through the housing and is connected to the hook. The friction sleeve is sleeved around the spring and fixed inside the housing, and the spring is in frictional contact with the inner wall of the friction sleeve.

[0010] Furthermore, a first rubber strip is provided on the inner side of both the first and second semicircular rings.

[0011] Furthermore, a second rubber strip is provided on the inner side of the positioning ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a hand-cranked telescopic hook, a collar, a fixing ring, and a post. The post is inserted into the soil, and the fixing ring is secured to the tree trunk using a positioning component. After securing the post, the collar is then fixed to the top of the post, thus installing the hand-cranked telescopic hook. The hook can then be used to hook the branch to be shaped, and the steel wire rope is wound up and down using a hand-cranked winding mechanism to adjust the branch pulling strength. The operation is convenient and efficient. The positioning component allows the post to be fixed to fruit trees of different diameters, and adjusting the installation height of the collar can accommodate branch pulling needs at different heights, thereby improving the overall flexibility and practicality of the branch pulling device.

[0015] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0016] like Figure 1 As shown, a fruit tree branch puller includes a hand-cranked telescopic hook 1, a collar 2, a fixing ring 3, and a post 4. The fixing ring 3 is fixed to the lower end of the post 4 and sleeved on the tree trunk. The fixing ring 3 is provided with a positioning component for fixing the fixing ring 3 to the tree trunk. The collar 2 is detachably sleeved on the upper end of the post 4. The hand-cranked telescopic hook 1 includes a hand-cranked winding mechanism and a steel wire rope 14. The hand-cranked winding mechanism is fixed to the collar 2 and is used to wind up and unwind the steel wire rope 14. The end of the steel wire rope 14 is connected to a hook 13.

[0017] When pulling branches of fruit trees, insert the post 4 into the soil, and fix the fixing ring 3 onto the trunk through the positioning component to fix the post 4. Then fix the ring 2 onto the upper end of the post 4 to install the hand-cranked telescopic hook 1. Then use the hook 13 to hook the branch that needs to be shaped, and use the hand-cranked winding mechanism to wind and unwind the wire rope 14 to adjust the pulling intensity.

[0018] In this embodiment, the column 4 is a steel rod with anti-slip patterns. To enhance its stability, the bottom of the column 4 is equipped with ground nails that can be inserted into the soil. The hand-cranked telescopic hook 1 is welded to the collar 2. The collar 2 and the hand-cranked telescopic hook 1 form a branch-pulling system. Different numbers of branch-pulling systems can be installed on the column 4 according to usage requirements, and the installation height of the collar 2 can be adjusted to meet the branch-pulling requirements at different heights.

[0019] like Figure 4As shown, the collar 2 is formed by the engagement of a first semicircular ring 21 and a second semicircular ring 22. The opposite sides of the first semicircular ring 21 and the second semicircular ring 22 are respectively provided with a slot 24 and a buckle 25. The first semicircular ring 21 and the second semicircular ring 22 can be fixed together or disassembled through the engagement of the buckle 25 and the slot 24, thereby realizing the assembly and disassembly of the collar 2 on the column 4. A first rubber strip 23 is fixed to the inner side of both the first semicircular ring 21 and the second semicircular ring 22. When installing the collar 2, the first semicircular ring 21 and the second semicircular ring 22 are wrapped around the column 4, and the buckle 25 is simultaneously engaged with the slot 24, thus fixing the collar 2 to the column 4. The first rubber strip 23 increases the friction between the collar 2 and the column 4, making the tie-rod system stable on the column 4.

[0020] like Figure 2 As shown, the fixing ring 3 is formed by two semi-circular fixing plates that embrace each other. The ends of the two fixing plates are connected by fixing bolts 32. The outer side of one fixing plate is fixedly connected to the lower end of the column 4 by welding. The positioning assembly includes adjusting bolts 31 and arc-shaped positioning rings 33. There are two positioning rings 33, which are arranged opposite each other. Positioning sleeves 35 corresponding to the adjusting bolts 31 are fixed to the outer side of the positioning rings 33. The adjusting bolts 31 are threadedly connected to the fixing plates and rotatably connected to the corresponding positioning sleeves 35. When fixing the column 4, the two fixing plates are wrapped around the tree trunk and fixed together by fixing bolts 32. Then, by turning the adjusting bolts 31, the positioning rings 34 are driven to press tightly against the tree trunk, thereby fixing the fixing ring 3 to the tree trunk and thus fixing the column 4. By adjusting the position of the positioning rings 34 by adjusting bolts 31, the column 4 can be fixed to tree trunks of different diameters. A second rubber strip 34 is fixed inside the positioning ring 33, which can increase the friction between the positioning ring 33 and the tree trunk, making the fixing ring 3 less likely to slip off, improving the overall stability of the branch puller, and preventing damage to the tree trunk.

[0021] like Figure 3As shown, the hand-cranked telescopic hook 1 includes a housing, a crank handle 11, a hexagonal drive shaft 12, a rotating sleeve 17, a winding reel 15, a spring 18, and a friction sleeve 20. The rotating sleeve 17 is rotatably mounted inside the housing. The hexagonal drive shaft 12 is fixed on the crank handle 11. The hexagonal drive shaft 12 is inserted into the housing and engages with one end of the rotating sleeve 17. An inner ring 19 is fixed to the end of the rotating sleeve 17 opposite to the hexagonal drive shaft 12. The inner ring 19 has an opening. The ends of the inner ring 19 located on both sides of the opening are bent towards the center of the rotating sleeve 17. The spring 18 is sleeved on the inner ring 19. The two ends of the spring 18 are bent towards the center of the rotating sleeve 17 and engage with the ends of the inner ring 19 located on both sides of the opening. The bent portions on both sides of the opening abut against each other. The winding reel 15 is movably sleeved on the rotating sleeve 17 between the inner wall of the outer shell and the inner ring 19. A protrusion 16 is fixed on the side wall of the winding reel 15. The protrusion 16 is inserted between the spring 18 and the inner ring 19 along the opening of the inner ring 19. One end of the wire rope 14 is wound on the winding reel 15. The other end of the wire rope 14 passes through the outer shell and is connected to a hook 13. The friction sleeve 20 is sleeved around the spring 18 and fixed inside the outer shell by bolts. The spring 18 is in frictional contact with the inner wall of the friction sleeve 20.

[0022] In the initial state, the spring 18 is in frictional contact with the friction sleeve 20, making the spring 18 unable to rotate freely. Since the two ends of the spring 18 abut against the bent part on the inner ring 19, and the protrusion 16 on the winding reel 15 is inserted between the inner ring 19 and the spring 18, the winding reel 15 and the rotating sleeve 17 also cannot rotate freely, and the hand-cranked telescopic hook 1 is in a self-locking state. When pulling branches of fruit trees, first fix the post 4 with the fixing ring 3 and install the pulling system with the collar 2. Then, hook the branch of the fruit tree with the hook 13. Apply clockwise or counterclockwise rotational force through the crank 11 and the hexagonal prism drive axial rotating sleeve 17. The rotating sleeve 17 will drive the spring 18 to contract towards the center of the spring 18 through the bent part of the inner ring 19, so that the spring 18 disengages from the friction sleeve 20 and can rotate freely. Then, the rotating sleeve 17, the inner ring 19, the spring 18 and the winding reel 15 can rotate freely synchronously, so that the wire rope 14 can be wound or unwound through the winding reel 15 to adjust the pulling strength. When the crank 11 is released, the spring 18 automatically returns to its original position and re-engages with the friction sleeve 20. Then, the friction sleeve 20 applies friction to the spring 18, so that the spring 18 cannot rotate freely, thus fixing the winding reel 15 and achieving self-locking.

[0023] Finally, although embodiments of the present invention have been shown and described above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
