Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clamping device technology, specifically relating to a clamping device for fruit tree bark. Background Technology
[0002] In fruit tree planting and horticultural management, bark hooping is a key technique for regulating fruit tree growth. By wrapping wire or similar materials around the trunk and tightening them appropriately, the phloem is compressed to restrict the longitudinal transport of nutrients. This effectively inhibits excessive vegetative growth, balances vegetative and reproductive growth, and helps trees that are excessively vegetative to become moderately vegetative, thus improving fruit yield and quality. This technique is widely used in shaping and pruning apple, pear, and peach trees, as well as in controlling fruit production. However, current bark hooping operations rely on traditional manual methods. The wire is manually wrapped around the trunk, and then the ends are tightened using pliers or similar tools. This process is slow and inefficient. Utility Model Content
[0003] To address the above problems, the purpose of this utility model is to provide a bark tightening device for fruit trees. Through the cooperation of a motor and a wire clamping device, it can automatically tighten the wire around the outside of the bark of the fruit tree. Compared with the manual method of using pliers or other tools to clamp the two ends of the wire and twist the wire around the outside of the trunk, the operation is more convenient and the efficiency is far higher than the manual twisting method.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a bark tightening device for fruit trees, comprising a handle, a first mounting chamber at the top of the handle, a second mounting chamber screwed to one end of the first mounting chamber, a battery mounted inside the first mounting chamber, a fixing plate inside the second mounting chamber, a motor mounted on one side of the fixing plate, a shaft support seat inside the second mounting chamber, a shaft rotatably mounted inside the shaft support seat, one end of the shaft connected to the output end of the motor, and another end of the shaft connected to a wire clamping device, a wire winding and storage device at one end of the first mounting chamber, a telescopic measuring ruler mounted on the side of the first mounting chamber, and a control button on the side of the handle.
[0005] As a further improvement to the above technical solution: the top of the second installation compartment is provided with a heat dissipation channel.
[0006] The heat dissipation channel is used to dissipate heat from the motor.
[0007] To hold the wire: As a further improvement to the above technical solution: the wire clamping device includes a connecting bracket fixed to the rotating shaft, one end of the connecting bracket being connected to a fixed base, the inner side of the fixed base being provided with a first clamping groove and a second clamping groove, a first locking screw and a second locking screw being threadedly installed on the side plate of the fixed base, one end of the first locking screw and one end of the second locking screw being fixedly connected to a first knob and a second knob respectively, and the other end of the first locking screw and the other end of the second locking screw being rotatably connected to a first clamping block and a second clamping block respectively.
[0008] One end of the cut wire is placed between the first clamping groove and the serrated groove of the first clamping block. The first locking screw is rotated by the first knob. The transmission between the first locking screw and the fixed base drives the first clamping block to slide along the inside of the first clamping groove, so that the first clamping groove and the first clamping block cooperate to clamp one end of the wire. Then, the other end of the wire is wrapped around the back of the tree trunk and bent forward, so that this end is placed between the second clamping groove and the serrated groove of the second clamping block. The second locking screw is rotated by the second knob. The transmission between the second locking screw and the fixed base drives the second clamping block to slide along the inside of the second clamping groove, so that the second clamping groove and the second clamping block cooperate to clamp this end of the wire. At this time, both ends of the wire are clamped and fixed, and the wire and this device cooperate to form a closed loop structure around the tree trunk.
[0009] To improve clamping stability: As a further improvement to the above technical solution: serrated grooves are provided on one side of the first clamping groove and the second clamping groove, and on one side of the first clamping block and the second clamping block.
[0010] The beneficial effects of this improvement are: the first clamping groove and the second clamping groove of the wire clamping device cooperate with the first clamping block and the second clamping block to clamp the wire, and the design of the serrated groove increases the clamping friction of the wire and improves the clamping stability.
[0011] To ensure the stability of this device during the tightening of the wire: As a further improvement to the above technical solution: an L-shaped bracket is installed at the bottom of the second installation compartment, and one end of the L-shaped bracket is connected to an arc-shaped support plate.
[0012] The beneficial effect of this improvement is that when the wire is twisted, the arc-shaped support plate is pressed against the tree trunk, so that the device remains stable during the tightening of the wire.
[0013] As a further improvement to the above technical solution: the wire winding and storage device includes a roller mounting frame fixed to the first mounting chamber, a roller is rotatably mounted on one side of the roller mounting frame, a wire roll is sleeved on the outer side of the roller, and a limit bolt is threaded to one end of the roller.
[0014] Wire spools are used for winding and storing wire. The wire spool can be released by rotating the drum and pulling the wire on the outside of the spool. The limit bolts are used to prevent the wire spool from falling off the outside of the drum.
[0015] For the control of this device: As a further improvement to the above technical solution: the first installation compartment is equipped with a controller, which is electrically connected to the control button and the motor respectively.
[0016] The controller is used to control the operation of the motor, and the control buttons are used to send control command signals to the controller to control the operation and stop of the motor.
[0017] In summary, the beneficial effects of this case are as follows: This device, through the cooperation of a motor and a wire clamping device, can automatically tighten wire around the outside of the bark of fruit trees. Compared with the manual method of using pliers or other tools to clamp the two ends of the wire and twist it around the outside of the trunk, this method is more convenient and far more efficient. The device uses a wire drum to wind and store the wire, and with the addition of a telescopic measuring ruler, the trunk diameter can be quickly determined when tightening the bark of a fruit tree. It also makes it easy to measure and cut the appropriate length of wire for tightening the bark, avoiding waste caused by cutting the wire too long.

A rotating shaft support 7 is also provided inside the second mounting chamber 4. A rotating shaft 8 is rotatably installed inside the rotating shaft support 7. One end of the rotating shaft 8 is connected to the output end of the motor 6. One end of the rotating shaft 8 is connected to a wire clamping device 10. A wire winding and storage device is provided at one end of the first mounting chamber 2. A telescopic measuring ruler 27 is installed on the side of the first mounting chamber 2. A control button 28 is provided on the side of the handle 1.
[0022] This device, in conjunction with the motor 6 and the wire clamping device 10, can automatically tighten the wire around the outside of the bark of fruit trees. Compared with the manual method of using pliers or other tools to clamp the two ends of the wire and twist it around the outside of the trunk, this method is more convenient and far more efficient. The device uses the wire drum 25 to wind and store the wire. With the addition of the telescopic measuring ruler 27, the diameter of the trunk can be quickly determined when tightening the bark of a fruit tree. It is also convenient to measure and cut the appropriate length of wire for tightening the bark, avoiding waste caused by cutting the wire too long.
[0023] The top of the second installation compartment 4 is provided with a heat dissipation channel 9.
[0024] The heat dissipation slot 9 is used to dissipate heat from the motor 6.
[0025] The wire clamping device 10 includes a connecting bracket 11 fixed to the rotating shaft 8. One end of the connecting bracket 11 is connected to the fixed base 12. The inner side of the fixed base 12 is provided with a first clamping groove 13 and a second clamping groove 14. A first locking screw 17 and a second locking screw 19 are threadedly installed on the side plate of the fixed base 12. One end of the first locking screw 17 and one end of the second locking screw 19 are respectively fixedly connected to a first knob 18 and a second knob 20. The other end of the first locking screw 17 and the other end of the second locking screw 19 are respectively rotatably connected to a first clamping block 15 and a second clamping block 16.
[0026] One end of the cut wire is placed between the first clamping groove 13 and the serrated groove of the first clamping block 15. The first locking screw 17 is rotated by the first knob 18. The first clamping block 15 is driven to slide along the inside of the first clamping groove 13 through the transmission between the first locking screw 17 and the fixed base 12, so that the first clamping groove 13 and the first clamping block 15 cooperate to clamp one end of the wire. Then, the other end of the wire is bent forward after passing around the back of the tree trunk, so that this end is placed between the second clamping groove 14 and the serrated groove of the second clamping block 16. The second locking screw 19 is rotated by the second knob 20. The second clamping block 16 is driven to slide along the inside of the second clamping groove 14 through the transmission between the second locking screw 19 and the fixed base 12, so that the second clamping groove 14 and the second clamping block 16 cooperate to clamp this end of the wire. At this time, both ends of the wire are clamped and fixed, and the wire and this device cooperate to form a closed loop structure around the tree trunk.
[0027] Serrated grooves are provided on one side of the first clamping groove 13 and the second clamping groove 14, and on one side of the first clamping block 15 and the second clamping block 16.
[0028] The first clamping groove 13 and the second clamping groove 14 of the wire clamping device 10 cooperate with the first clamping block 15 and the second clamping block 16 to clamp the wire. The serrated groove design increases the clamping friction of the wire and improves the clamping stability.
[0029] An L-shaped bracket 21 is installed at the bottom of the second installation compartment 4, and one end of the L-shaped bracket 21 is connected to the arc-shaped support plate 22.
[0030] When twisting the wire, the arc-shaped support plate 22 is pressed against the tree trunk to keep the device stable during the tightening process.
[0031] The wire winding and storage device includes a roller mounting frame 23 fixed to the first mounting chamber 2. A roller 24 is rotatably mounted on one side of the roller mounting frame 23. A wire roll 25 is sleeved on the outer side of the roller 24. A limit bolt 26 is threadedly connected to one end of the roller 24.
[0032] The wire drum 25 is used for winding and storing wire. The wire drum 25 can be rotated by the drum 24. When the wire on the outside of the wire drum 25 is pulled, the wire is released. The limit bolt 26 is used to prevent the wire drum 25 from falling off the outside of the drum 24.
[0033] The first installation compartment 2 is equipped with a controller 29, which is electrically connected to the control button 28 and the motor 6 respectively.
[0034] The controller 29 is used to control the operation of the motor 6, and the control button 28 is used to send control command signals to the controller 29 to control the operation and stop of the motor 6.
[0035] Working principle and usage process of this utility model: When using this device, the diameter of the tree trunk can be measured by unfolding the telescopic measuring ruler 27 to determine the length of the wire needed to tighten the trunk. Then, one end of the wire wound on the outside of the wire reel 25 is pulled outward, and the length of the wire is measured again using the telescopic measuring ruler 27 to ensure that the wire can wrap around the tree trunk once, with an extra 10 to 15 centimeters. Then, the wire is cut with wire cutters, and one end of the cut wire is placed between the first clamping groove 13 and the serrated groove of the first clamping block 15. The first locking screw 17 is rotated by the first knob 18, and the first clamping block 15 is slid along the inside of the first clamping groove 13 through the transmission between the first locking screw 17 and the fixed base 12, so that the first clamping groove 13 and the first clamping block 15... The device works by clamping one end of the wire, then bending the other end forward after it passes behind the tree trunk, placing it between the serrated grooves of the second clamping groove 14 and the second clamping block 16. The second locking screw 19 is rotated via the second knob 20, causing the second clamping block 16 to slide along the inside of the second clamping groove 14 through the transmission between the second locking screw 19 and the fixing base 12. This engages the second clamping groove 14 and the second clamping block 16, clamping one end of the wire. At this point, both ends of the wire are clamped and fixed, forming a closed loop around the tree trunk. The arc-shaped support plate 22 is then pressed against the tree trunk to stabilize the device during the wire tightening process. The controller 2 is activated via the control button 28. 9. Sending a command, controller 29 controls motor 6 to drive shaft 8 to rotate, thereby driving fixed base 12 to rotate. Since the two ends of the wire are fixed to form a closed loop, during rotation, the parts of the wire near the two ends will twist together, and the wire will gradually tighten around the trunk. By controlling the operation and stopping of motor 6, the tightening force can be adjusted, ultimately making the wire tightly adhere to the bark, achieving the tightening of the bark. By squeezing the phloem, the transport of nutrients through the bark is restricted, inhibiting the vegetative growth of the fruit tree, turning a vigorous tree into a moderate one, balancing vegetative and reproductive growth. After completing the bark tightening work, the first knob 18 and the second knob 20 are rotated in the opposite direction to release the clamping between the first clamping groove 13 and the first clamping block 15 on one end of the wire, and the first... After the two clamping slots 14 and the second clamping block 16 clamp the other end of the wire, the bark tightening work of a fruit tree can be completed. In summary, this device, through the cooperation of the motor 6 and the wire clamping device 10, can automatically tighten the wire on the outside of the bark of the fruit tree. Compared with the manual method of using pliers or other tools to clamp the two ends of the wire and twist the wire wrapped around the outside of the trunk, the operation is more convenient and the efficiency is far higher than the manual twisting method. This device uses the wire drum 25 to wind and store the wire. With the setting of the telescopic measuring ruler 27, the trunk diameter can be quickly determined when tightening the bark of a fruit tree, and it is convenient to measure and cut the appropriate length of wire for tightening the bark, avoiding waste caused by cutting the wire too long.
