Description

Technical Field

[0001] This application relates to the field of fruit tree planting technology, specifically to a fruit tree branch puller. Background Technology

[0002] Fruit trees are plants that produce edible fruits. In the process of fruit tree cultivation, branch pulling is an important technical measure. The main functions of branch pulling include improving the light conditions of the tree canopy, promoting flower bud differentiation, adjusting the growth vigor of branches, and improving the tree structure. In existing technologies, branch pulling is mostly carried out by ropes. One end of the rope is tied to the trunk, and the other end is tied to the branch, forcing the branch to change its angle. This method can easily cause damage to the trunk and branches at the binding points, thus affecting the growth of fruit trees. Therefore, a fruit tree branch pulling device is proposed. Utility Model Content

[0003] The purpose of this application is to address the technical problem that branch pulling is mostly done with ropes, one end of which is tied to the trunk and the other end to the branch, forcing the branch to change angle. This method easily leads to damage to the trunk and the tied part of the branch, thus affecting the growth of the fruit tree. This application provides a fruit tree branch pulling device.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] A fruit tree branch puller, comprising:

[0006] Two arc-shaped plates are hinged together and surround the outer periphery of the main trunk. A sliding frame is slidably mounted on the arc-shaped plates. A screw threaded through the arc-shaped plates has its free end rotatably connected to the sliding frame. A rubber block that abuts and overlaps with the main trunk is mounted on the sliding frame. Multiple support members and multiple fixed seats are respectively mounted on opposite sides of the arc-shaped plates. The support members are in contact with the ground and are used to support the arc-shaped plates. A telescopic rod is hinged to the fixed seat. A connecting plate is hinged to the free end of the telescopic rod. A branch pulling mechanism is mounted on the connecting plate. The branch pulling mechanism includes two pull ropes, each mounted on the connecting plate. The free end of each pull rope is equipped with a hook. It also includes binding cloth wrapped around the branch. The binding cloth is equipped with four fixing rings arranged in pairs. The two hooks are respectively hooked and engaged with the two sets of fixing rings.

[0007] Furthermore, one of the arc-shaped plates is provided with a fixing block, the fixing block having a notch, and the other arc-shaped plate is hinged with a screw that engages with the notch, the screw being threaded with a locking nut that abuts against and overlaps with the fixing block.

[0008] Furthermore, the sliding frame has a groove, and multiple sliding rods, each with its free end connected to a rubber block, are slidably arranged in the groove. A relief spring is sleeved on the sliding rod between the rubber block and the groove.

[0009] Furthermore, the support member includes an outer cylinder hinged to an arc-shaped plate, an inner cylinder slidably disposed on the outer cylinder and locked or unlocked between the two by a positioning member, a support plate that contacts the ground is hinged to the free end of the inner cylinder, and a plurality of ground nails with their free ends penetrating into the ground are movably inserted through the support plate.

[0010] Furthermore, the positioning element includes a screw cylinder disposed on the outer cylinder, the free end of the screw cylinder being provided with a plurality of arc-shaped pieces that abut against and overlap with the inner cylinder, the arc-shaped pieces being constructed with a guide slope, the screw cylinder being threadedly fitted with a positioning cylinder, the positioning cylinder being constructed with a transition slope.

[0011] Furthermore, the telescopic rod includes an outer rod hinged to a fixed base, an inner rod slidably disposed on the outer rod, a connecting plate hinged to the free end of the inner rod, a plurality of positioning holes opened on the inner rod, a positioning rod hinged to the outer rod and a torsion spring disposed between the two, and a positioning block disposed on the positioning rod that engages with the positioning hole.

[0012] Furthermore, the fixed base has two positioning slots, and the two ends of the outer rod hinge shaft are respectively inserted into the two positioning slots. The fixed base is provided with locking members that are the same number as the positioning slots and correspond one-to-one. The outer rod is locked or unlocked by the locking members.

[0013] Furthermore, the locking component includes a limiting rod slidably disposed on the fixed base, a wedge-shaped block is provided at the free end of the limiting rod, the wedge-shaped block abuts and overlaps with the hinge axis of the outer rod, and a return spring sleeved on the limiting rod is provided between the wedge-shaped block and the fixed base.

[0014] The beneficial effects of this application are as follows:

[0015] This application abandons the existing method of branch pulling using ropes. In use, two arc-shaped plates are placed around the outer perimeter of the trunk, so that the support is in contact with the ground. The support supports the arc-shaped plates, and the two screw rods are driven to rotate, causing the two sliding frames to slide in opposite directions until they are close to each other until both rubber blocks are in contact with the trunk. Then, the binding cloth is wrapped around the branch, and the telescopic rod and connecting plate are rotated, so that the two hooks engage with the two sets of fixing rings. Then the length of the telescopic rod is reduced, thereby pulling the branch. Because the contact area between the trunk and the rubber blocks is large, and the contact area between the branch and the binding cloth is also large, damage to the trunk and branches can be avoided, ensuring the growth of the fruit tree, and therefore it is more practical.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1-12 As shown, one embodiment of this application discloses a fruit tree branch puller, comprising:

[0031] Two arc-shaped plates 1 are hinged together and surround the outer periphery of the main structure. A sliding frame 2 is slidably mounted on the arc-shaped plates 1, sliding horizontally. A threaded rod 3, with its free end rotatably connected to the sliding frame 2, is threaded through the arc-shaped plates 1. The threaded rod 3 is horizontal. A rubber block 4, vertically oriented and located inside the sliding frame 2, is mounted on the sliding frame 2 and abuts against the main structure. Multiple support members and multiple fixing seats 5 are respectively provided on opposite sides of the arc-shaped plates 1. The support members are located at the bottom of the arc-shaped plates 1, and the fixing seats 5 are fixed to the top of the arc-shaped plates 1. The support members are in contact with the ground and are used for... The curved plate 1 is supported by a telescopic rod hinged to a fixed base 5. The length of the telescopic rod is adjustable. The free end of the telescopic rod is hinged to a connecting plate 6. A branch pulling mechanism is provided on the connecting plate 6. The branch pulling mechanism includes two pull ropes 7, both of which are set on the connecting plate 6. The pull ropes 7 are fixed to the connecting plate 6. The free end of the pull ropes 7 is provided with a hook 8. The hook 8 is fixed to the free end of the pull ropes 7. The mechanism also includes a binding cloth 9 wrapped around the branch. The binding cloth 9 is provided with four fixing rings 10, which are arranged in pairs. The fixing rings 10 are fixed to the binding cloth 9. The two hooks 8 are hooked and engaged with the two sets of fixing rings 10 respectively.

[0032] In use, two arc-shaped plates 1 are placed around the outer periphery of the main trunk, so that the support is in contact with the ground. The support supports the arc-shaped plates 1, improving the stability of use. The two screw rods 3 are driven to rotate, so that the two sliding frames 2 slide in opposite directions until they are close to each other, until the two rubber blocks 4 are in contact with the main trunk. Then, the binding cloth 9 is wrapped around the branch, so that the telescopic rod and the connecting plate 6 are rotated, so that the two hooks 8 are hooked and engaged with the two sets of fixing rings 10. Then the length of the telescopic rod is reduced, so that the branch is pulled and forced to change the angle of the branch.

[0033] In summary, this application abandons the existing method of pulling branches using ropes. In use, two arc-shaped plates 1 are placed around the outer periphery of the trunk, so that the support member is in contact with the ground. The support member supports the arc-shaped plates 1, and drives the two screw rods 3 to rotate, causing the two sliding frames 2 to slide in opposite directions until they are close to each other, until the two rubber blocks 4 are in contact with the trunk. Then, the binding cloth 9 is wrapped around the branch, and the telescopic rod and connecting plate 6 are rotated, so that the two hooks 8 are hooked and engaged with the two sets of fixing rings 10. Then the length of the telescopic rod is reduced, thereby pulling the branch. Because the contact area between the trunk and the rubber blocks 4 is large, and the contact area between the branch and the binding cloth 9 is large, damage to the trunk and branches can be avoided, ensuring the growth of the fruit tree, and therefore it is more practical.

[0034] like Figure 3As shown, in some embodiments, a fixing block 11 is provided on one of the arc-shaped plates 1, the fixing block 11 is fixed on one of the arc-shaped plates 1, the fixing block 11 has a notch 12, the notch 12 is in the horizontal direction, and a screw 13 is hinged on the other arc-shaped plate 1 to engage with the notch 12, the screw 13 is in the horizontal direction, and a locking nut 14 that abuts against and overlaps with the fixing block 11 is threaded on the screw 13;

[0035] Referring to the above, when the two arc-shaped plates 1 are surrounded on the outer periphery of the main body, the screw 13 is rotated and engaged with the notch 12, and the locking nut 14 is tightened and engages with the fixing block 11, thereby locking the two arc-shaped plates 1.

[0036] like Figure 5 As shown, in some embodiments, the sliding frame 2 has a groove 15, and a plurality of sliding rods 16, whose free ends are all connected to the rubber block 4, are slidably arranged in the groove 15. The sliding rods 16 slide in the horizontal direction, and a relief spring 17 is provided between the rubber block 4 and the groove 15 and sleeved on the sliding rod 16. The relief spring 17 is in the horizontal direction and its two ends are fixedly connected to the rubber block 4 and the groove 15 respectively.

[0037] Referring to the above, in the initial state, both the rubber block 4 and the sliding rod 16 are in their initial positions, and the yielding spring 17 is in its natural state. During the growth of the fruit tree, the trunk will gradually thicken, forcing the rubber block 4 to retract into the groove 15, driving the sliding rod 16 to slide to its limit position, and the yielding spring 17 will be squeezed, thereby providing sufficient space for the growth of the trunk and avoiding affecting the normal growth of the trunk.

[0038] like Figures 6-8 As shown, in some embodiments, the support includes an outer cylinder 18 hinged to an arc plate 1, an inner cylinder 19 slidably disposed on the outer cylinder 18 and locked or unlocked between the two by a positioning member, the inner cylinder 19 sliding along the length direction of the outer cylinder 18, and a support plate 20 in contact with the ground hinged to the free end of the inner cylinder 19, and a plurality of ground nails 21 with their free ends penetrating into the ground moving through the support plate 20.

[0039] Referring to the above, during use, the outer cylinder 18 and inner cylinder 19 are unlocked by the positioning component, allowing the inner cylinder 19 to slide and the overall length of the outer cylinder 18 and inner cylinder 19 to be adjusted. Then, the outer cylinder 18 and inner cylinder 19 are locked by the positioning component. After that, the outer cylinder 18 is rotated, causing the inner cylinder 19 to rotate together, so that the support plate 20 is horizontal and in contact with the ground. This allows the ground nail 21 to move vertically through the support plate 20 and have its free end penetrate into the ground, thereby supporting the arc plate 1 and improving its stability.

[0040] like Figure 8As shown, in some embodiments, the positioning element includes a screw cylinder 22 disposed on the outer cylinder 18. The screw cylinder 22 is fixed on the outer cylinder 18 and the two are coaxially distributed. The free end of the screw cylinder 22 is provided with a plurality of arc-shaped pieces 23 that abut against and overlap with the inner cylinder 19. The plurality of arc-shaped pieces 23 are arranged in a ring array and are all fixed on the free end of the screw cylinder 22. The arc-shaped pieces 23 can undergo elastic deformation. A guide slope is constructed on the arc-shaped pieces 23. A positioning cylinder 24 is threaded on the screw cylinder 22. A transition slope is constructed on the positioning cylinder 24.

[0041] Referring to the above, in the initial state, the positioning cylinder 24 is in the extreme position, and the transition slope is in contact with multiple guide slopes, forcing multiple arc-shaped pieces 23 to undergo elastic deformation and all of them to abut and overlap with the inner cylinder 19, thereby locking the outer cylinder 18 and the inner cylinder 19. In use, the positioning cylinder 24 is rotated to the initial position, the transition slope moves away from multiple guide slopes, and multiple arc-shaped pieces 23 are reset to their natural state and move away from the inner cylinder 19, thereby unlocking the outer cylinder 18 and the inner cylinder 19.

[0042] like Figures 10-11 As shown, in some embodiments, the telescopic rod includes an outer rod 25 hinged to a fixed base 5, an inner rod 26 slidably disposed on the outer rod 25, the inner rod 26 sliding along the length direction of the outer rod 25, a connecting plate 6 hinged to the free end of the inner rod 26, a plurality of positioning holes 27 provided on the inner rod 26, the plurality of positioning holes 27 being arrayed along the length direction of the inner rod 26, a positioning rod 28 hinged to the outer rod 25 and a torsion spring 29 disposed between the two, the two ends of the torsion spring 29 being fixedly connected to the outer rod 25 and the positioning rod 28 respectively, a positioning block 30 provided on the positioning rod 28 for insertion and engagement with the positioning hole 27, the positioning block 30 being fixed on the positioning rod 28 and the two being perpendicularly distributed, the free end of the positioning block 30 being conical;

[0043] Referring to the above, in the initial state, both the positioning rod 28 and the positioning block 30 are in their initial positions, the torsion spring 29 is in its natural state, and the free end of the positioning block 30 is inserted into one of the positioning holes 27, thereby locking the outer rod 25 and the inner rod 26. In use, the positioning rod 28 is rotated to its limit position, causing the positioning block 30 to move out of the positioning hole 27. The torsion spring 29 is compressed, thereby unlocking the outer rod 25 and the inner rod 26. Then, the positioning rod 28 is released, the torsion spring 29 returns to its natural state, and the positioning rod 28 and the positioning block 30 rotate together to their initial positions. The free end of the positioning block 30 is inserted into one of the positioning holes 27, thereby relocking the outer rod 25 and the inner rod 26.

[0044] like Figure 10As shown, in some embodiments, the fixed base 5 has two positioning slots 31, which are vertical. The two ends of the hinge shaft of the outer rod 25 are respectively inserted into the two positioning slots 31. The fixed base 5 is provided with locking members that are the same number as the positioning slots 31 and correspond one-to-one. The outer rod 25 is locked or unlocked by the locking members.

[0045] Referring to the above, during use, the outer rod 25 is installed on the fixed base 5, and the two ends of the hinge shaft of the outer rod 25 are respectively located in the two positioning grooves 31. The outer rod 25 is locked by the locking device, and the hinge shaft of the outer rod 25 cannot be removed from the positioning groove 31. At the same time, it does not affect the rotation of the outer rod 25. When not in use, the outer rod 25 can be unlocked by the locking device, so that the hinge shaft of the outer rod 25 can be removed from the positioning groove 31, thereby disassembling the outer rod 25 for easy transportation and transfer. The number of outer rods 25 can also be adjusted according to actual use needs to improve the flexibility and applicability of use.

[0046] like Figure 10 As shown, in some embodiments, the locking element includes a limiting rod 32 slidably disposed on the fixed base 5. The limiting rod 32 slides in the horizontal direction. A wedge block 33 is provided at the free end of the limiting rod 32. The wedge block 33 is horizontal and fixed at the free end of the limiting rod 32. The wedge block 33 abuts against the hinge axis of the outer rod 25. A return spring 34 is provided between the wedge block 33 and the fixed base 5 and sleeved on the limiting rod 32. The return spring 34 is horizontal and its two ends are fixedly connected to the wedge block 33 and the fixed base 5 respectively.

[0047] Referring to the above, during use, both the limiting rod 32 and the wedge block 33 are in their initial positions, the return spring 34 is in its natural state, and the hinge shaft of the outer rod 25 is in contact with the plane of the wedge block 33. Due to the obstruction of the wedge block 33, the hinge shaft of the outer rod 25 cannot exit the positioning groove 31, thus locking the outer rod 25. Conversely, the limiting rod 32 and the wedge block 33 move together to their extreme positions, the return spring 34 is compressed, and due to the removal of the obstruction of the wedge block 33, the hinge shaft of the outer rod 25 can exit the positioning groove 31, thus locking the outer rod 25. The outer rod 25 is unlocked, and then the limiting rod 32 and the wedge block 33 are released. The two move together to the initial position, and the return spring 34 returns to its natural state. When the hinge shaft of the outer rod 25 enters the positioning groove 31, it first contacts and overlaps with the inclined surface of the wedge block 33. Through the transition effect of the inclined surface, the limiting rod 32 and the wedge block 33 are forced to move together to the limit position, and the return spring 34 is compressed. Then the return spring 34 returns to its natural state, and the limiting rod 32 and the wedge block 33 move together to the initial position, thereby locking the outer rod 25.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
