Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forestry insect prevention, in particular to a forestry insect prevention device. Background Art
[0002] As we all know, forestry insect control devices are important tools for protecting forest resources and maintaining ecological balance. For trunk-boring pests, most of them use physical control methods such as yellow tape wrapping or tree rings, which are laid around the tree trunks to form a physical barrier to prevent pests and diseases on the ground, such as trunk-boring pests, from climbing onto the tree trunks, thereby reducing the damage of pests and diseases to forests.
[0003] The existing tree rings are cut to the appropriate size according to the diameter and height of the tree trunk and fixed around the tree trunk. Nails, tapes and other tools are used to ensure that the tree rings fit tightly to the tree trunk and are not easy to fall off. However, the tree rings are mostly disposable during use and cannot be recycled. In addition, when the diameter of the tree grows larger during use, the tree rings need to be disassembled and reinstalled, which increases the workload of the operator and reduces work efficiency. In order to solve the above problems, a forestry insect control device is needed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See Figures 1 to 5 A forestry insect-proof device includes a square box 1, a first baffle 2, a circular shaft 3 and a crank 9.
[0024] Preferably, the square box 1 serves as the bearing base of the entire device. In order to reduce the overall weight and provide protection, it is made of lightweight and sturdy polypropylene plastic. The inside carries the shrunken and unused rubber belt 5. The first baffle 2 is also made of polypropylene plastic, and the first baffle 2 is pasted inside the square box 1 to limit the retraction of the rubber belt 5 to prevent the rubber belt 5 from shifting during the retraction process. The circular shaft 3 is rotatably set at the center position inside the square box 1, and the circular shaft 3 and the first baffle 2 are rotatably set. The circular shaft 3 serves as the winding base of the rubber belt 5. The rubber belt 5 is wound and retracted by rotating the circular shaft 3. The crank handle 9 is pasted on the bottom of the circular shaft 3 to assist the operator in rotating the circular shaft 3.
[0025] First, see Figures 3-5 In this embodiment, it includes a through hole 4, a rubber belt 5, a first round rod 6 and a short rod 7.
[0026] Preferably, in order to facilitate the recovery of the rubber belt 5, the through hole 4 is square in shape and its height is equal to the width of the rubber belt 5. The through hole 4 is opened on one side of the square box 1. One end of the rubber belt 5 is pasted on the circular shaft 3 and contacts the inside of the square box 1 and the bottom of the first baffle 2. The rubber belt 5 can be made of soft natural rubber to facilitate better wrapping around the tree trunk. By wrapping the rubber belt 5 around the tree trunk, it prevents trunk-boring pests from climbing up the tree trunk and causing damage to the tree. The first round rod 6 is pasted on the other end of the rubber belt 5. The rubber belt 5 is extended and wrapped around the tree trunk by pulling the first round rod 6. In order to facilitate limiting the position of the first round rod 6, the pulled out rubber belt 5 is wrapped around the tree trunk once and then re-fixed on one side of the square box 1. Two L-shaped short rods 7 are pasted on one side of the square box 1. By pasting one end of the L-shaped short rod 7 to one side of the square box 1, a concave groove is formed between the L-shaped short rod 7 and one side of the square box 1, and the position of the first round rod 6 is limited by this concave groove.
[0027] Then, see Figure 3 In this embodiment, it includes a gear 8 and a limiting component 10.
[0028] In the above embodiment, the gear 8 is adhered to one end of the circular shaft 3, and the gear 8 is located above the first baffle 2 inside the square box 1, and is used to assist in limiting the length of the circular shaft 3 to retract and release the rubber belt 5. The gear teeth of the gear 8 can be selected from gears 8 with eight or more teeth, which is convenient for adjusting the precise length of the rubber belt 5. The limit assembly 10 is installed on the top of the square box 1. The limit assembly 10 is fitted with the tooth grooves on the gear 8 to limit the rotation of the gear 8, thereby controlling the length of the circular shaft 3 to retract and release the rubber belt 5.
[0029] Secondly, see Figure 3 In this embodiment, it includes a pull rod 11, a second baffle 12, a spring 13 and a second round rod 14.
[0030] In the above embodiment, in order to prevent the limit assembly 10 from breaking when limiting the gear 8, the pull rod 11, the second baffle 12, and the second round rod 14 are all made of relatively hard steel materials. The pull rod 11 is slidably set on the top of the square box 1, and the second baffle 12 is welded to the bottom of the pull rod 11. One end of the spring 13 is welded inside the square box 1, and the other end is welded to the top of the second baffle 12. The pull rod 11 and the second baffle 12 are installed on the top of the square box 1 through the spring 13 and maintain stable sliding to drive the second round rod 14. One end of the second round rod 14 is vertically welded to the bottom of the second baffle 12, and the other end fits with the tooth groove on the gear 8 to limit the movement of the gear 8.
[0031] Again, see Figures 1 to 3 In this embodiment, it includes a first long plate 15 and a first arc-shaped rubber plate 16.
[0032] Preferably, in order to reduce the overall weight of the device, the first long plate 15 is made of polypropylene plastic and there are two of them. The first long plate 15 is pasted on one side of the square box 1 to connect the first curved rubber plate 16 and support the entire insect-proof device. In order to prevent the first long plate 15 from exerting a large pressure on the tree trunk and damaging the tree trunk, the first curved rubber plate 16 is pasted on one side of the first long plate 15. The first curved rubber plate 16 can be made of natural rubber with a soft texture so that it can fit tightly against the tree trunk to enhance the wrapping. At the same time, several bumps are provided on one side of the first curved rubber plate 16 to increase friction and prevent the insect-proof device from sliding down.
[0033] In addition, see Figure 3 In this embodiment, it includes a short plate 17, a first limiting rod 18 and a second limiting rod 19.
[0034] In the above embodiment, there are four short plates 17, which are respectively pasted on the two ends of the corresponding first long plates 15 to fix the first limiting rod 18. In order to make the rubber belt 5 close to the tree trunk and reduce the corresponding gap, two first limiting rods 18 are set and pasted on one side of the corresponding short plate 17, and each first limiting rod 18 is in contact with the rubber belt 5. At the same time, the length of the first limiting rod 18 is greater than the first round rod 6, which makes it easier for the first round rod 6 to drive the rubber belt 5 to pass through the gap formed by the first limiting rod 18, the first long plate 15 and the short plate 17. The second limiting rod 19 is pasted on the inside of the square box 1 and is parallel to the through hole 4. The second limiting rod 19 is in contact with the rubber belt 5 to prevent the rubber belt 5 from being damaged by friction around the through hole 4.
[0035] In addition, see Figure 1 In this embodiment, it includes a long rod 20, a slide groove 21, a convex rod 22 and a bracket 23.
[0036] In the above embodiment, two long rods 20 are pasted in parallel on the bottom of the square box 1, and two slide grooves 21 are respectively opened at the bottom of the corresponding long rods 20, which are used as the sliding basis of the convex rod 22. In order to prevent the convex rod 22 from falling off in the slide groove 21, the slide groove 21 is opened by only passing through one end. The two convex rods 22 are slidably set on the corresponding slide grooves 21, serving as a detachable basis for the bracket 23, which is convenient for the installation and storage of the device. In order to prevent the insect-proof device from tilting due to its own gravity during use, two brackets 23 are pasted on the bottom of the convex rod 22 to provide support force to prevent the device from tilting.
[0037] The long rod 20, the slide groove 21, the convex rod 22 and the bracket 23 cooperate with each other to form a detachable supporting device, so that the insect-proof device can reduce storage space when not in use and is easy to transport.
[0038] Finally, see Figure 1 In this embodiment, it includes a curved plate 24 and a second curved rubber plate 25 .
[0039] Preferably, in order to prevent the bracket 23 from causing damage to the trunk and to better fit the trunk, an arc-shaped plate 24 is pasted on the bottom of the bracket 23 to reduce pressure and reduce damage to the trunk caused by the bracket 23. At the same time, in order to increase friction and prevent the arc-shaped plate 24 from sliding downward, a second arc-shaped rubber plate 25 with several bumps is pasted on one end of the arc-shaped plate 24.
[0040] Working principle:
[0041] When using the forestry insect-proof device, the forestry insect-proof device is first placed in the desired position. The operator first assembles the two convex rods 22 and the slide groove 21 together, so that the first curved rubber plate 16 is close to the desired winding position of the tree trunk, and at the same time, the second curved rubber plate 25 is close to the lower trunk to provide corresponding support. Then, the pull rod 11 is pulled up to shrink the spring 13 and drive the second baffle 12 to rise, so that the second round rod 14 rises and disengages from the contact surface of the gear 8. Then, the operator pulls the first round rod 6 to drive the rubber belt 5 to bypass the second limiting rod 19 and pass through the through hole 4 while passing through the gap formed by the first limiting rod 18, the first long plate 15 and the short plate 17. After wrapping the rubber belt 5 around the tree trunk, the first round rod 6 is placed in a concave groove formed by the L-shaped short rod 7 and one side of the square box 1. , the position of the first round rod 6 is limited by this concave groove, and then the crank 9 is rotated to drive the round shaft 3 to rotate so that the rubber belt 5 is tightened and close to the tree trunk. After tightening, the pull rod 11 is released to reset the limit assembly 10, and the second round rod 14 is fitted with the tooth groove on the gear 8 to limit the rotation of the gear 8, thereby fixing the length of the rubber belt 5 so that the rubber belt 5 is always close to the tree trunk. When the tree grows and the trunk diameter becomes larger, it is only necessary to pull the pull rod 11 and then rotate the crank 9 to adjust the length of the rubber belt 5 so that the rubber belt 5 remains close to the tree trunk and then release the pull rod 11. When insect prevention is not needed, the device is recycled and stored until the next use. In this process, the insect prevention device can be recycled, and there is no need to disassemble and reinstall a new insect prevention device when the tree grows and the diameter becomes larger, which reduces the workload of the operator and improves work efficiency.
[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
