Description

Technical Field

[0001] The invention relates to the technical field of forestry prevention and control, and in particular to a device for dual prevention and control of purple elm leaf beetles. Background Art

[0002] The purple leaf beetle is an insect belonging to the family Chrysomelidae, order Coleoptera. It mainly harms plants of the genus Ulmus, such as the common elm, yellow elm, and spring elm. It is one of the main leaf-eating pests of elm. Especially in early spring, when it breaks out, it often eats up all the new leaves, seriously affecting the growth and development of elm. Traditional control is mainly physical control (artificially shaking the tree) and chemical control (using toxic pesticides for spraying). The former method is simple and easy, but the control effect is poor, especially for tall elms. The latter has obvious control effects, but pesticides will pollute the environment, especially in agricultural and pastoral areas, where a large amount of residual pesticides poses a safety hazard to local livestock.

[0003] Previous studies have found that the purple night beetle has insufficient flying ability and climbs trees to damage leaves. Therefore, blocking its crawling route is an effective way to prevent it.

[0004] Therefore, we have made improvements to this problem and proposed a dual control device for the purple elm leaf beetle. Summary of the invention

[0005] The technical problem to be solved by the present invention is: utilizing the biological habit of the elm purple night beetle that has insufficient flying ability to block its crawling route, thereby preventing the elm purple night beetle from crawling along the tree trunk to the branches and leaves to harm the leaves.

[0006] In order to achieve the above-mentioned invention objectives, the present invention provides a dual control device for elm purple leaf beetles, including a protective cover, the protective cover is bent as a whole into an inverted funnel shape that is thin at the top and thick at the bottom, the protective cover is a hard plastic product, the inner wall and side edges of the protective cover are affixed with double-sided tape, the upper end of the protective cover is fixedly connected with a clamp, a soft sponge ring is installed on the inner side of the clamp and the trunk joint, a support frame is arranged inside the protective cover, and an auxiliary mechanism is rotatably connected to the outer side of the support frame.

[0007] As a further solution of the present invention, the protective cover comprises a plastic ring, and a connecting groove is provided in the middle of the inner side surface of the plastic ring.

[0008] As a further solution of the present invention, the clamp includes a connecting strip, which is fixedly connected to the upper end of the protective cover, the outer side surface of the connecting strip is provided with a mounting groove, a rack is installed inside the mounting groove, the inner side surface of the connecting strip is provided with a clamping groove, the clamping groove is slidably engaged with the rack, the outer end of the connecting strip is provided with a notch, a clamping block is movably installed inside the notch, a spring sheet is installed at the outer end of the clamping block, the spring sheet is fixedly connected to the surface of the connecting strip, and a spring is connected to the connecting strip in the middle of the spring sheet.

[0009] As a further solution of the present invention, the protective cover is made entirely of plastic material, and is unfolded into a semicircular ring shape, and after bending, the ends overlap to form a funnel shape.

[0010] As a further solution of the present invention, the support frame includes four columns, and a top block is installed on the top of the column. The top block is in the shape of a right-angled triangle with the tip facing upward. A telescopic frame is connected in the middle of the four columns, and a rotating groove is opened in the middle of the column and the telescopic frame.

[0011] As a further scheme of the present invention, the auxiliary mechanism includes a rotating ring, which is an open ring and is rotatably installed inside a rotating groove. A connecting rod is fixedly installed on the upper end of the rotating ring, and a rotating frame is vertically installed on the upper end of the connecting rod. A cleaning brush is hinged on the rotating frame. A blade is also connected to the side of the rotating ring, and the blade has cutting edges on both the upper and lower sides, and a fan blade is installed at the front end of the blade.

[0012] As a further solution of the present invention, the double-sided adhesive tape is composed of a plurality of trapezoidal adhesive strips, one side of the double-sided adhesive tape is connected to the protective cover, and the other side of the double-sided adhesive tape is coated with plant powder.

[0013] As a further solution of the present invention, the installation height of the protective cover from the ground is 10 to 15 centimeters.

[0014] The device for dual prevention and control of purple elm leaf beetle provided by the present invention has the following beneficial effects:

[0015] 1. By designing a protective cover around the bottom of the tree trunk and taking advantage of the physiological characteristics of the elm night beetle's insufficient flying ability, the elm night beetle's path to crawl along the tree trunk is blocked, preventing the elm night beetle from climbing up the tree and damaging the leaves.

[0029] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples of the specification. The following examples are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] like Figure 1-Figure 9 As shown, this embodiment proposes a dual control device for elm purple leaf beetle, including a protective cover 1, the protective cover 1 is bent as a whole into an inverted funnel shape that is thin at the top and thick at the bottom, the protective cover is made of hard plastic, the inner wall and side edges of the protective cover 1 are affixed with double-sided tape 5, the upper end of the protective cover 1 is fixedly connected with a clamp 2, and a soft sponge ring 6 is installed on the inner side of the clamp 2 and the trunk. A support frame 3 is arranged inside the protective cover 1, and an auxiliary mechanism 4 is rotatably connected to the outer side of the support frame 3.

[0031] The protective cover 1 includes a plastic ring 11, and a connecting groove 12 is opened in the middle of the inner side of the plastic ring 11. The plastic ring 11 is surrounded by the outer side of the tree trunk. The setting of the connecting groove 12 facilitates the connection of the double-sided tape 5, so that the double-sided tape 5 can not only connect the head and tail of the protective cover 1, but also apply plant powder to achieve dual prevention and control of elm purple night beetle.

[0032] The clamp 2 includes a connecting strip 21, which is fixedly connected to the upper end of the protective cover 1. A mounting groove 22 is provided on the outer side surface of the connecting strip 21, and a rack 25 is installed inside the mounting groove 22. A clamping groove 23 is provided on the inner side surface of the connecting strip 21, and the clamping groove 23 is slidably sleeved with the rack 25. A notch 24 is provided on the outer end of the connecting strip 21, and a clamping block 27 is movably installed inside the notch 24. A spring 26 is installed on the outer end of the clamping block 27. The spring 26 is fixedly connected to the surface of the connecting strip 21, and a spring 28 is connected to the connecting strip 21 in the middle. The clamp 2 is connected to the top of the protective cover 1. Through the head and tail connection of the clamp 2, the position where the upper end of the protective cover 1 contacts the tree trunk is reinforced, and the gap between the protective cover 1 and the tree trunk is filled to prevent small insects from crawling. At the same time, the connection tightness of the clamp 2 is automatically adjusted as the trunk grows to avoid adverse effects on the growth of the tree.

[0033] The protective cover 1 is made of plastic as a whole. The protective cover 1 is unfolded into a semicircular shape, and after bending, the ends overlap to form a funnel. The material and shape of the protective cover 1 cause the feet of the purple night beetle to slip when crawling on the protective cover 1, and it cannot continue to crawl up the tree trunk, thereby blocking the crawling path of the purple night beetle and preventing the purple night beetle from gnawing on the tree trunk, branches and leaves. In addition, the protective cover 1 is easy to wrap around the tree trunk and can also be used on the outside of tree trunks of different diameters, which is convenient and quick.

[0034] The support frame 3 includes four columns 31, and a top block 32 is installed on the top of the column 31. The top block 32 is a right-angled triangle with the tip facing upward. A telescopic frame 33 is connected in the middle of the four columns 31. A rotating groove 34 is opened in the middle of the column 31 and the telescopic frame 33. The bottom of the column 31 is rooted in the soil. The bottom surface of the protective cover 1 is supported by the top block 32 at the top of the column 31 to determine the installation height of the protective cover 1. At the same time, the opening shape of the protective cover 1 is supported by the top block 32 to keep the protective cover 1 in a trumpet shape, thereby playing a role in preventing and controlling the purple night beetle.

[0035] The auxiliary mechanism 4 includes a rotating ring 41, which is an open ring and is rotatably mounted inside the rotating groove 34. A connecting rod 42 is fixedly mounted on the upper end of the rotating ring 41, and a rotating frame 43 is vertically mounted on the upper end of the connecting rod 42. A cleaning brush 44 is hinged on the rotating frame 43. A blade 45 is also connected to the side of the rotating ring 41. The upper and lower sides of the blade 45 are provided with blades, and a fan blade 46 is installed at the front end of the blade 45. The rotating ring 41 is rotatably connected to the support frame 3, and the upper end of the rotating ring 41 The installed cleaning brush 44 is against the inner wall of the protective cover 1, and while supporting and shaping the protective cover 1, it rotates to clean the inner wall of the protective cover 1 to prevent the purple night beetle from staying inside the protective cover 1. The blade 45 is installed on the side of the rotating ring 41. The fan blade 46 installed on the blade 45 drives the auxiliary mechanism 4 to rotate along the support frame 3 as a whole in windy weather, so that the blade 45 cuts the weeds and vegetation near the tree trunk to prevent the weeds from growing and providing a crawling path for the purple night beetle, thereby effectively blocking the purple night beetle.

[0036] The double-sided adhesive tape 5 is composed of several trapezoidal adhesive strips, and one side of the double-sided adhesive tape 5 is connected to the protective cover 1, and the other side of the double-sided adhesive tape 5 is coated with plant powder, such as the stems and leaves of bitter bean, wolfsbane, and stem and leaf powder of Atractylodes lancea. The stems and leaves of bitter bean have a special smell, which can drive away the purple night beetle by the smell and prevent the purple night beetle from staying near the tree trunk. A part of the double-sided adhesive tape 5 is in the overlapping position of the protective cover 1. At this time, the upper and lower surfaces of the double-sided adhesive tape 5 are bonded to the two ends of the protective cover 1, thereby connecting the two ends of the protective cover 1.

[0037] The installation height of the protective cover 1 from the ground is 10 to 15 cm, which is close to the ground, can not only prevent and control the purple leaf beetle of elm, but also prevent the head of livestock from entering the protective cover, which is safe and effective.

[0038] Specifically, when the dual control device for elm purple leaf beetles is in use: the support frame 3 and the auxiliary mechanism 4 are both annular structures with an opening in the middle. The support frame 3 is placed in a circle around the tree trunk, the bottom of the column 31 is driven into the soil, and the auxiliary mechanism 4 is rotatably connected inside the rotating groove 34. The protective cover 1 and the clamp 2 are surrounded around the tree trunk and supported on the bottom surface of the protective cover 1 by the support frame 3 and the auxiliary mechanism 4. The two ends of the protective cover 1 are connected along the surface of the trunk, and the two ends of the clamp 2 are tightly wrapped around the trunk. The device is placed 10 to 15 cm close to the ground on the trunk, and the physiological characteristics of the elm purple leaf beetle's insufficient flying ability are used to block the elm purple night beetle's crawling path along the tree trunk, preventing the elm purple night beetle from climbing up the tree and damaging the leaves. At the same time, double-sided tape 5 is used to fix the bitter bean stems on the inner side of the protective cover 1. The leaf powder is smeared on the inner wall of the protective cover 1. The stems and leaves of bitter bean have a special smell. The principle of plant allelopathy is used to drive away the purple night beetle, prevent the purple night beetle from staying near the tree trunk, or crawling from the inside of the protective cover 1 to the outside, so as to achieve the dual effect of blocking the crawling path of the purple night beetle. A cleaning brush 44 and a blade 45 are installed on the rotating ring 41. A fan blade 46 is installed at the end of the blade 45. The fan blade 46 is rotated by the wind to make the blade 45 cut the weeds near the root of the tree to prevent the weeds from growing and providing a crawling path for the purple night beetle. The cleaning brush 44 is installed inside the protective cover 1 to clean the purple night beetle crawling into the protective cover 1, so as to further expel the purple night beetle. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
