TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ancient tree repair and insect prevention, and particularly relates to an ancient tree and famous tree insect prevention device. BACKGROUND

[0002] Ancient tree and famous tree protection has been a maintenance measure for endangered ancient trees. Many ancient trees have large or small tree holes, which seriously damage the tree body and affect the growth of the ancient trees. After water accumulation, the ancient trees are more vulnerable to insect invasion, and the tree trunks are prone to large-area rotting or even hollowing, which poses a risk of collapse at any time.

[0003] After pruning and disinfection, the tree hole repair is filled with repair materials. The tree hole repair work is generally filled with hard objects such as bricks and stones, and is sealed by smearing cement and sand. There is usually a gap between the surface of the repaired material and the tree hole. In the early stage of repair completion, rainwater is easy to penetrate along the repaired gap, causing bacteria to breed and causing the tree to rot inside. Thus, the ancient trees and famous trees are again invaded by pests. Once the tree inside rots, the pests will invade the rotted part, causing insect damage. In order to solve the problem that the ancient trees and famous trees are again rotted in the early stage after repair due to rainwater penetration and other reasons, causing the tree inside to rot and causing insect damage, we propose an ancient tree and famous tree insect prevention device. SUMMARY

[0004] Therefore, the utility model aims at providing an ancient tree and famous tree insect prevention device to solve the problem that the ancient trees and famous trees are again rotted in the early stage after repair due to rainwater penetration and other reasons, causing the tree inside to rot and causing insect damage.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] An ancient tree and famous tree insect prevention device comprises two half rings, the inside of the half ring is hollow, an adjusting block is slidably installed in the inside of the half ring, a spring is connected between the adjusting block and the inside of the half ring, a connecting buckle is rotatably installed at the two ends of the half ring, a roller one is rotatably installed in the inside of the half ring, a plastic film is wound on the roller one, an open slot one is formed in the outer ring of the half ring, one end of the plastic film is pulled out from the open slot one, an open slot two is formed in the top of the half ring, a roller two is rotatably installed on the top of the half ring, a rainproof cloth is wound on the roller two, one end of the rainproof cloth is pulled out from the open slot two, the end of the rainproof cloth pulled out is rolled to have a perforation, and an elastic rope is inserted into the perforation.

[0007] On the basis of the above technical scheme, the utility model further has the following improvements:

[0008] Further, a rubber layer is fixedly installed in the inner ring of the adjusting block, so that the tree trunk at the clamped position is protected from damage.

[0009] Further, the thickness of the semi-ring inner ring is higher than the thickness of the outer ring; rainwater can flow down from the outside of the plastic film along the inclined angle of the upper surface of the semi-ring, and cannot accumulate on the semi-ring.

[0010] Further, a through groove is arranged inside the semi-ring below the first roller, and the through groove contains an insect repellent; the through groove is arranged below the first roller, so that the plastic film on the first roller is contaminated with the smell of the insect repellent, and the effect of insect repellent is achieved when the plastic film is pulled out for use.

[0011] Further, the elastic rope is knotted at both ends; the elastic rope is prevented from being retracted into the perforation, and the use of the elastic rope for fixing the rainproof cloth is affected.

[0012] The device is simple in structure and practical, can block rainwater from the repaired tree hole in the initial stage, avoids the rainwater from penetrating into the inside of the tree through the repaired gap of the tree hole, and causes the bacteria in the inside of the tree to breed again, the tree to rot, and the insect damage to occur, can be used for trees with different diameters and different sizes of tree holes, and the use range is expanded.

[0020] The utility model will be described in detail in combination with the drawings and specific embodiments:

[0021] As Figures 1 to 5 shown, an ancient tree insect prevention device, comprising two half rings 1, the inside of the half ring 1 is hollow, the inside of the half ring 1 is slidingly installed with an adjusting block 2, the adjusting block 2 is connected with a spring 3 inside the half ring 1, the two ends of the half ring 1 are rotatably installed with a connecting buckle 4, and the two half rings are connected through the connecting buckle 4. The adjusting block 2 is aligned with the tree trunk, and the half ring 1 is pushed inward from both sides. The adjusting block 2 slides into the half ring 1, the spring 3 is compressed, after the two half rings 1 are completely fitted, the connecting buckle 4 on the half ring 1 is pressed down, the half ring 1 is loosened, the spring 3 cannot recover to the original state under the limitation of the connecting buckle 4, but the elastic force generated by being compressed makes the adjusting block 2 clamp the tree trunk. The inside of the half ring 1 is rotatably installed with a roller 5, the plastic film 6 is wound on the roller 5, the opening groove 7 is formed on the outer ring of the half ring 1, one end of the plastic film 6 is pulled out from the opening groove 1, the opening groove 2 8 is formed on the top of the half ring 1, the roller 9 is rotatably installed on the top of the half ring 1, the rainproof cloth 10 is wound on the roller 9, one end of the rainproof cloth 10 is pulled out from the opening groove 2 8, the end of the rainproof cloth 10 pulled out is rolled with a perforation 11, the telescopic rope 12 is pulled through the perforation 11, and the rainproof cloth 10 is fixed on the tree trunk by tightening the telescopic rope 12, so that the inner ring of the two half rings 1 is shielded, and the tree trunk is not eroded by rainwater. The roller 5 and the roller 9 are made of flexible soft metal material.

[0022] Specifically, the rubber layer 13 is fixedly installed in the inner ring of the adjusting block 2; the tree trunk at the clamped part is protected from being damaged.
