Description

Technical Field

[0001] This utility model relates to the technical field of branch adjustment devices, and in particular to a fruit tree branch adjuster. Background Technology

[0002] Pruning is an important measure in fruit tree cultivation and management. Pruning is to shape the canopy into a certain shape according to the biological characteristics of the fruit tree, combined with the natural conditions and management characteristics of the orchard. It also involves using various techniques and measures such as heading back, thinning, and slowing down the growth to achieve the goals of early fruiting, high yield, high quality, high efficiency, and low cost, especially to overcome the various drawbacks caused by natural growth.

[0003] The existing tie ropes are all in individual pieces, which are not easy for staff to recycle after use and are usually discarded. This easily leads to waste and high costs. At the same time, the tie ropes are not easy to use when binding other heavy objects, which affects the staff's use and indirectly reduces the staff's work efficiency. An existing patent (publication number: CN221284004U) discloses a fruit tree branch adjuster device, including a winding reel, a pulling component connected to the winding reel with one end passing through the side wall of the winding reel and extending to the outside; a winding component connected to the winding reel, with one end of the pulling component extending into the winding component; a connecting component connected to the winding reel, with two mounting components on the connecting component; and a counterweight component on one side of each of the two mounting components. During use, the operator can directly pull out the winding tape, hook it onto a branch, and then fix the other end to the trunk via the connecting tape, making it convenient for the operator. After use, with the assistance of a coil spring, the winding tape can be retracted into the winding reel, further enabling the device to be reused and improving resource utilization. Simultaneously, the winding tape is protected when not in use as it remains in the winding reel.

However, most existing fruit tree branch adjustment devices can only adjust one branch at a time, making it difficult to meet the needs of adjusting multiple branches of a fruit tree. Furthermore, when adjusting angles, they are mostly equidistant angle adjustments, which cannot meet the needs of fine angle adjustments.

[0005] To address this, a fruit tree branch adjuster is proposed. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: A fruit tree branch adjuster includes a first clamping block 1, a second clamping block 2 on the left side of the first clamping block 1, and an angle-adjustable telescopic component 3 on the right side of the first clamping block 1. The surface of the angle-adjustable telescopic component 3 is covered with a plurality of free hook components 4. The free hook assembly 4 includes a mounting ring 41, which is sleeved on the surface of the angle-adjustable telescopic assembly 3. Two connecting plates 42 are bolted to the right side of the mounting ring 41. A rotating shaft 43 is rotatably arranged between the two connecting plates 42. A take-up roller 44 is sleeved on the surface of the rotating shaft 43. A steel wire rope 45 is wound around the surface of the take-up roller 44. One end of the steel wire rope 45 is connected to a hook 46. The front side of the rotating shaft 43 extends to the front side of the front connecting plate 42 and is bolted to a first turntable 47.

[0020] In this embodiment: First, the first clamping block 1 and the second clamping block 2 of the fruit tree branch adjuster are fitted together and clamped onto the main trunk of the fruit tree. Then, the angle-adjustable telescopic component 3 provides a platform for the free hook component 4 to move. The mounting ring 41 of the free hook component 4 is fitted onto the surface of the angle-adjustable telescopic component 3, allowing it to move up and down and rotate freely in the horizontal direction. The operator can move the mounting ring 41 to a suitable up or down position according to the position of the fruit tree branch that needs to be adjusted. The two connecting plates 42 are respectively bolted to the mounting ring 41 to provide installation space for the rotating shaft 43. Then, a rope take-up roller is fitted onto the rotating shaft 43 to provide installation space for the steel wire rope 45. The hook 46 connected to one end of the steel wire rope 45 is hung on the branch that needs to be adjusted. By rotating the first turntable 47, the take-up roller 44 is driven to rotate, thereby realizing the adjustment of the branch. In this way, multiple free hook components 4 can adjust multiple fruit tree branches at the same time, meeting the needs of adjusting multiple branches of a fruit tree.

[0021] Specifically, such as Figure 3 , Figure 1 As shown, the angle-adjustable telescopic assembly 3 includes a mounting box 31, the left side of which is bolted to the right side of the first clamping block 1.

[0022] Specifically, such as Figure 3 As shown, a fixing rod 32 is bolted to the bottom of the mounting box 31. A telescopic rod 33 is rotatably mounted on the surface of the fixing rod 32. A movable hole 34 is provided on the top of the mounting box 31. The telescopic rod 33 extends upward through the movable hole 34, and the surface of the telescopic rod 33 slides in contact with the inner wall of the mounting ring 41.

[0023] Specifically, such as Figure 3 , Figure 4 As shown, the front side of the mounting box 31 has an angle adjustment hole 35, and the front side of the telescopic rod 33 is bolted with a pin 36, which passes through the angle adjustment hole 35 and extends forward.

[0024] In this embodiment: the left side of the mounting box 31 of the angle-adjustable telescopic component 3 is bolted to the right side of the first clamping block 1. A telescopic rod 33 is rotatably mounted on the surface of the fixed rod 32 at the bottom inside the mounting box 31. The telescopic rod 33 extends upward through the movable hole 34 opened at the top of the mounting box 31, and the surface of the telescopic rod 33 slides in contact with the inner wall of the mounting ring 41 of the free hook component 4. When it is necessary to adjust the left and right and up and down positions of the free hook component 4, the telescopic rod 33 can extend, retract and rotate, providing a moving platform for the free hook component 4. When adjusting the angle of the telescopic rod 33, since the mounting box 31 has an angle adjustment hole 35 on the front side, the pin 36 bolted to the front side of the telescopic rod 33 passes through the angle adjustment hole 35 and extends forward. The operator can push or pull the pin 36 to make the telescopic rod 33 rotate around the fixed rod 32, thereby realizing the angle adjustment and fine adjustment of the telescopic rod 33, and thus realizing the adjustment of the position of the free hook component 4, better adapting to the needs of adjusting fruit tree branches in different positions.

[0025] Specifically, such as Figure 6 As shown, a ratchet 5 is fitted on the front side of the surface of the rotating shaft 43, a pin 6 is bolted to the front side of the front connecting plate 42, a rotating ring 7 is fitted on the surface of the pin 6, a wire feeding locking plate 8 is bolted to the right side of the rotating ring 7, and the right side of the bottom of the wire feeding locking plate 8 is in contact with the surface of the ratchet 5.

[0026] Specifically, such as Figure 6 , Figure 5 , Figure 1 As shown, a fixing block 9 is bolted to the bottom of the front side of the front connecting plate 42. A tension spring 10 is connected between the top of the fixing block 9 and the bottom of the wire-laying locking plate 8. A pull rod 11 is bolted to the right side of the top of the wire-laying locking plate 8. A first fixing pin 12 is threaded to the left side of the mounting ring 41. The first fixing pin 12 is in contact with the surface of the telescopic rod 33. A telescopic limiting sleeve 13 is sleeved on the surface of the telescopic rod 33. A second fixing pin 14 is threaded to the left side of the telescopic limiting sleeve 13. The right side of the second fixing pin 14 is in contact with the surface of the telescopic rod 33.

[0027] In this embodiment: When the free hook assembly 4 performs the take-up and release operations, its internal components such as the ratchet 5 and the release locking plate 8 work together. The ratchet 5 is sleeved on the front side of the rotating shaft 43, and the rotating ring 7 is sleeved on the surface of the pin 6 bolted to the front side of the front connecting plate 42. The bottom right side of the release locking plate 8 bolted to the right side of the rotating ring 7 contacts the surface of the ratchet 5. When the first turntable 47 is rotated to drive the take-up roller 44 to take up the line, due to the action of the ratchet 5 and the release locking plate 8, the take-up roller 44 can only rotate in one direction, preventing the hook 46 connected to the steel wire rope 45 from falling off due to accidental rotation. The fixing block 9 bolted to the bottom of the front side of the front connecting plate 42 is connected to the bottom of the release locking plate 8. A tension spring 10 keeps the line-laying locking plate 8 in contact with the ratchet 5. When line-laying is required, the operator pulls the lever 11 bolted to the top right of the line-laying locking plate 8 to overcome the tension of the tension spring 10, causing the line-laying locking plate 8 to disengage from the ratchet 5. At this time, the take-up roller 44 can rotate freely to lay the line. The first fixing pin 12, which is threaded on the left side of the mounting ring 41, contacts the surface of the telescopic rod 33 to fix the position of the mounting ring 41 on the telescopic rod 33, ensuring that the free hook assembly 4 is in the appropriate position to adjust the fruit tree branches. The cooperation of the second fixing pin 14 and the telescopic limit sleeve 13 can control the telescopic length of the telescopic rod 33.

[0028] Specifically, such as Figure 4 As shown, the front side of the pin 36 is provided with a screw thread 15, the surface of the screw thread 15 is threaded with a screw sleeve 16, the front side of the screw sleeve 16 is bolted with a second turntable 17, the front side of the mounting box 31 is provided with anti-slip stripes 18, and the rear side of the screw sleeve 16 contacts the anti-slip stripes 18.

[0029] In this embodiment: when fine-tuning the angle of the telescopic rod 33 of the angle-adjustable telescopic assembly 3, components such as the pin 36, the screw-in sleeve 16, and the second turntable 17 play a key role. The front surface of the pin 36 is provided with a screw-in thread 15, and the screw-in sleeve 16 is threaded onto the surface of the screw-in thread 15. The front side of the screw-in sleeve 16 is bolted to the second turntable 17. The front side of the mounting box 31 is provided with anti-slip stripes 18, and the rear side of the screw-in sleeve 16 contacts the anti-slip stripes 18. When the angle of the telescopic rod 33 needs to be adjusted, the operator rotates the second turntable 17. Turntable 17, due to the threaded engagement between screw-in sleeve 16 and pin 36, allows screw-in sleeve 16 to move back and forth on pin 36. When screw-in sleeve 16 moves backward and comes into close contact with anti-slip stripe 18, friction is generated, preventing telescopic rod 33 from rotating freely, thus fixing telescopic rod 33 at the adjusted angle position. When the angle needs to be adjusted again, the second turntable 17 is rotated in the opposite direction, causing screw-in sleeve 16 to move forward and disengage from the close contact with anti-slip stripe 18. At this time, pin 36 can be pushed again to adjust the angle of telescopic rod 33.

[0030] Specifically, such as Figure 2As shown, rubber pads 19 are bolted to the inner walls of the first clamping block 1 and the second clamping block 2. Guide rods 20 are bolted to the front and rear sides of the right side of the second clamping block 2. Guide holes 21 are opened on the front and rear sides of the interior of the first clamping block 1. The guide rods 20 and guide holes 21 are used in conjunction. Bolts 22 are threaded between the front and rear sides of the interior of the first clamping block 1 and the second clamping block 2.

[0031] In this embodiment: when the fruit tree branch adjuster is installed on the main trunk of the fruit tree, the first clamping block 1 and the second clamping block 2 play a clamping role. Rubber pads 19 are bolted to the inner walls of both the first clamping block 1 and the second clamping block 2. When clamping the main trunk, the rubber pads 19 increase the friction with the main trunk while preventing damage. Guide rods 20 are bolted to the front and rear sides of the right side of the second clamping block 2. Guide holes 21 are opened on the front and rear sides inside the first clamping block 1. The guide rods 20 and guide holes 21 are matched. When used together, the first clamping block 1 and the second clamping block 2 are used to ensure the accuracy and stability of the relative movement of the two clamping blocks. The operator places the first clamping block 1 and the second clamping block 2 on both sides of the main trunk of the fruit tree, inserts the guide rod 20 into the guide hole 21, and then threaded bolts 22 are connected between the front and rear sides of the first clamping block 1 and the second clamping block 2. By tightening the bolts 22, the first clamping block 1 and the second clamping block 2 are gradually brought closer together and finally firmly clamped on the main trunk of the fruit tree, providing stable support for the entire fruit tree branch adjuster.

[0032] Working principle: First, the first clamping block 1 and the second clamping block 2 with rubber pads 19 are clamped onto the main trunk of the fruit tree through the guide rod 20 and guide hole 21. The bolts 22 are tightened to make it stable and provide support for the adjuster. The mounting box 31 of the angle-adjustable telescopic component 3 is connected to the first clamping block 1. The telescopic rod 33 inside can rotate and extend. The extension length of the telescopic rod 33 can be controlled by the cooperation of the second fixing pin 14 and the telescopic limit sleeve 13. By pushing or pulling the pin 36 that passes through the angle adjustment hole 35 of the mounting box 31, the angle of the telescopic rod 33 can be adjusted and finely adjusted. Rotating the second turntable 17 makes the screw-in sleeve 16 fit against the anti-slip stripes of the mounting box 31. 18. Contact or separation allows for fixing or readjusting the angle of the telescopic rod 33, providing a positional movement platform for the free hook assembly 4. The mounting ring 41 of the free hook assembly 4 is fitted onto the surface of the telescopic rod 33, allowing for vertical movement and horizontal rotation. Its position is fixed by the first fixing pin 12. Rotating the first turntable 47 drives the take-up roller 44 to take in the line. The ratchet 5 and the line release locking plate 8 are used to achieve unidirectional rotation to prevent the hook 46 from falling off. Pulling the pull rod 11 disengages the line release locking plate 8 from the ratchet 5 to release the line. The hook 46 at one end of the steel wire rope 45 is hung on the branch to be adjusted. Then, the first turntable 47 is rotated in the opposite direction to take in the line to adjust the branch. Multiple free hook assemblies 4 can adjust multiple branches simultaneously.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
