Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural pest control equipment, specifically relating to a trapping electric grid insect-killing rack for chestnut pest control. Background Technology

[0002] In chestnut cultivation, pest control is a crucial step in ensuring chestnut yield and quality. Currently, some growers use traditional insecticidal lamps for pest control. While these lamps can effectively trap pests by utilizing their phototaxis, they are not the best solution.

[0003] Among the prior art, there is an insecticidal lamp disclosed in patent application number CN202210376245.9, which includes an insecticidal lamp mounting column and an insecticidal lamp body mounted on the mounting column; the insecticidal lamp body includes an upper base, a lower base, and an electric grid insecticidal part movably mounted between the upper base and the lower base; the upper base is also provided with a vibration module, which drives the electric grid insecticidal part to vibrate; the vibration module includes a vibrating plate and a vibration motor. The electric grid insecticidal unit of this invention can vibrate at a certain high frequency during operation, which can effectively prevent larger insects from getting stuck between the inner and outer grids, thereby ensuring the battery life and insecticidal efficiency of the insecticidal lamp. However, in this technical solution, the height is fixed during use, which makes it difficult to adapt to chestnut trees at different growth stages and heights, resulting in poor trapping effect on pests at high or low locations. On the other hand, after a period of use, the electric grid of traditional insecticidal lamps will be covered with a large number of dead insects killed by electric shock. If it is not cleaned in time, it will affect the normal operation of the electric grid and reduce the insecticidal efficiency. Manual cleaning is not only time-consuming and laborious, but also poses certain safety hazards.

[0004] In view of this, we propose a trap-type electric grid insect-killing rack for chestnut pest control. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a trap-type electric grid insect-killing rack for preventing chestnut insects.

[0006] The technical solution of this utility model is:

[0007] A chestnut insect-trapping electric grid insect-killing frame includes a base. A threaded column is slidably installed at the center of the base. An adjusting block is fixedly installed at the center of the top of the base. The inner ring wall of the adjusting block is threadedly connected to the outer wall of the threaded column. An insect-attracting lamp is installed on the top of the threaded column, and an electric shock net is fixedly connected to the outside of the insect-attracting lamp. A connecting shaft is fixedly connected to the top of the electric shock net, and a top plate is fixedly connected to the top of the connecting shaft. Two guide rails are symmetrically fixedly connected to the bottom of the top plate. A vertically movable mounting frame is installed between the two guide rails. A movable ring is rotatably connected inside the mounting frame. A cleaning brush is installed on the inner ring wall of the movable ring. A limiting plate is fixedly connected to the bottom of each guide rail. The threaded column is slidably installed up and down at the center of the base and threadedly connected to the adjusting block. The height of the threaded column can be flexibly adjusted by rotating the adjusting block, thus adapting to chestnut trees of different heights and pest activity areas. The insect-attracting lamp attracts pests, and the electric shock net kills nearby pests with electricity. The guide rail and movable mounting frame at the bottom of the top plate, together with the rotating movable ring and cleaning brush inside the mounting frame, facilitate the cleaning of the electric shock net and maintain its working efficiency.

[0008] As a preferred technical solution, the base is fixedly connected to at least three legs arranged in a circular array at its bottom. This provides a stable support structure for the insecticide rack on the ground, enhancing the overall stability of the rack.

[0009] As a preferred technical solution, the bottom of the adjusting block is coaxially integrally formed with a connecting ring, which is rotatably connected to an annular groove formed on the top of the base. Two second handles are symmetrically fixedly connected to the outer circumference of the adjusting block. The rotatable connection between the connecting ring at the bottom of the adjusting block and the annular groove of the base makes the adjustment block rotate more smoothly and reduces frictional resistance. The two second handles on the outer circumference of the adjusting block allow the operator to apply force to rotate the adjusting block, realizing convenient adjustment of the height of the threaded column and improving the ease of use.

[0010] As a preferred technical solution, two vertically arranged limiting grooves are symmetrically formed on the outer circumference of the threaded column, and a limiting block that is slidably connected to the limiting grooves is integrally formed inside the base. This prevents the threaded column from rotating during lifting and ensures that the threaded column can only slide up and down in a vertical direction.

[0011] As a preferred technical solution, two bearings are symmetrically installed on the upper and lower parts of the outer circumference of the movable ring. The inner and outer rings of the bearings are respectively interference-fitted with the movable ring and the mounting bracket. This prevents the threaded column from rotating during lifting and ensures that the threaded column can only slide up and down in a vertical direction.

[0012] As a preferred technical solution, a rubber ring is fixedly connected to the outer circumference of the movable ring between two bearings. A mounting groove is provided inside the base, and a drive block is rotatably mounted within the mounting groove. The outer ring wall of the drive block is tightly fitted to the outer ring wall of the rubber ring. A rotary motor with an output coaxially fixed to the drive block is fixedly mounted on the top of the mounting frame. The rubber ring of the movable ring is tightly fitted to the drive block inside the base. The rotary motor drives the drive block, using friction to rotate the movable ring, thereby achieving the cleaning of the electrostatic mesh by the cleaning brush.

[0013] As a preferred technical solution, the mounting frame has two symmetrically symmetrically arranged through holes for two guide rails to pass through, and two first handles are symmetrically fixedly connected to the outer circumference of the mounting frame. The through holes on the mounting frame facilitate the passage of the guide rails, enabling the mounting frame to move up and down on the guide rails; the two first handles facilitate the operator to move the mounting frame and adjust the position of the cleaning brush to clean different parts of the electric shock net, making the operation more convenient and flexible.

[0014] As a preferred technical solution, when the bottom of the mounting bracket contacts the top of the limiting plate, the top of the mounting bracket is lower than the bottom of the electric shock net. This ensures that the mounting bracket will not affect the normal use of the electric shock net when it is not in use.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a threaded column that slides up and down the center of the base and is threadedly connected to an adjusting block. This allows for the adjustment of the threaded column by rotating the adjusting block, thus flexibly adjusting the height of the insect-attracting lamp and the electric shock net to suit chestnut trees of varying heights and insect activity areas. The insect-attracting lamp attracts insects, while the electric shock net kills nearby pests. The guide rail and movable mounting frame at the bottom of the top plate, along with the rotating ring and cleaning brush inside the mounting frame, facilitate cleaning of the electric shock net, maintaining its efficiency. A limiting plate restricts the downward movement of the mounting frame, ensuring structural stability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] The chestnut insect-trapping electric grid insect-killing frame includes a base 1. A threaded column 3 is slidably installed at the center of the base 1. An adjusting block 4 is fixedly installed at the center of the top of the base 1. The inner ring wall of the adjusting block 4 is threadedly connected to the outer wall of the threaded column 3. An insect-attracting lamp 7 is installed on the top of the threaded column 3, and an electric shock net 6 is fixedly connected to the outside of the insect-attracting lamp 7. A connecting shaft 5 is fixedly connected to the top of the electric shock net 6. A top plate 8 is fixedly connected to the top of the connecting shaft 5. Two guide rails 9 are symmetrically fixedly connected to the bottom of the top plate 8. A vertically movable mounting frame 10 is installed between the two guide rails 9. A movable ring 13 is rotatably connected inside the mounting frame 10. A cleaning brush 14 is installed on the inner ring wall of the movable ring 13. A limiting plate 90 is fixedly connected to the bottom of each guide rail 9. The threaded column 3 is slidably installed up and down through the center of the base 1 and threadedly connected to the adjusting block 4. This allows the threaded column 3 to be raised and lowered by rotating the adjusting block 4, thereby flexibly adjusting the height of the insect-attracting lamp 7 and the electric shock net 6 to adapt to chestnut trees of different heights and pest activity areas. The insect-attracting lamp 7 attracts pests, and the electric shock net 6 can kill nearby pests by electric shock. The guide rail 9 and the movable mounting bracket 10 at the bottom of the top plate 8, together with the rotating movable ring 13 and cleaning brush 14 inside the mounting bracket 10, facilitate the cleaning of the electric shock net 6 and maintain its working efficiency.

[0026] In a preferred embodiment, the base 1 has at least three legs 2 arranged in a circular array fixedly connected to its bottom. This provides a stable support structure for the insecticide rack on the ground, enhancing the overall stability of the rack.

[0027] In a preferred embodiment, the bottom of the adjusting block 4 is integrally formed with a connecting ring 41 on the same axis. The connecting ring 41 is rotatably connected to the annular groove 101 formed on the top of the base 1. Two second handles 40 are symmetrically fixedly connected to the outer circumference of the adjusting block 4. The rotatable connection between the connecting ring 41 at the bottom of the adjusting block 4 and the annular groove 101 of the base 1 makes the rotation of the adjusting block 4 smoother and reduces frictional resistance. The two second handles 40 on the outer circumference of the adjusting block 4 make it convenient for the operator to apply force to rotate the adjusting block 4, thereby realizing convenient adjustment of the height of the threaded column 3 and improving the ease of use.

[0028] In a preferred embodiment, two vertically arranged limiting grooves are symmetrically formed on the outer circumference of the threaded column 3, and a limiting block 100 integrally formed inside the base 1 is slidably connected to the limiting grooves. This prevents the threaded column 3 from rotating during lifting and lowering, ensuring that the threaded column 3 can only slide up and down in a vertical direction.

[0029] In a preferred embodiment, two bearings are symmetrically installed on the upper and lower parts of the outer circumference of the movable ring 13. The inner and outer rings of the bearings are respectively interference-fitted with the movable ring 13 and the mounting bracket 10. This prevents the threaded column 3 from rotating during lifting and lowering, ensuring that the threaded column 3 can only slide up and down in the vertical direction.

[0030] In a preferred embodiment, a rubber ring 15 is fixedly connected to the outer circumference of the movable ring 13 between two bearings. A mounting groove 18 is provided inside the base 1, and a drive block 16 is rotatably mounted within the mounting groove 18. The outer ring wall of the drive block 16 is tightly fitted to the outer ring wall of the rubber ring 15. A rotary motor 12, whose output is coaxially fixed with the drive block 16, is fixedly mounted on the top of the mounting bracket 10. The rubber ring 15 of the movable ring 13 is tightly fitted to the drive block 16 inside the base 1. The rotary motor 12 drives the drive block 16, using friction to rotate the movable ring 13, thereby enabling the cleaning brush 14 to clean the electrostatic mesh 6.

[0031] In a preferred embodiment, the mounting bracket 10 has two symmetrically symmetrically arranged through holes 17 for the two guide rails 9 to pass through, and two first handles 11 are symmetrically fixedly connected to the outer circumference of the mounting bracket 10. The through holes 17 on the mounting bracket 10 facilitate the passage of the guide rails 9, enabling the mounting bracket 10 to move up and down on the guide rails 9; the two first handles 11 facilitate the operator to move the mounting bracket 10 and adjust the position of the cleaning brush 14 to clean different parts of the electric shock mesh 6, making the operation more convenient and flexible.

[0032] In this preferred embodiment, when the bottom of the mounting bracket 10 contacts the top of the limiting plate 90, the top of the mounting bracket 10 is lower than the bottom of the electric shock net 6. This ensures that the mounting bracket 10 will not affect the normal use of the electric shock net 6 when it is not in use.

[0033] When using the chestnut insect-trapping electric grid insect-killing frame of this utility model, the operator rotates the second handle 40 on the outer circumference of the adjusting block 4. The adjusting block 4 rotates within the annular groove 101 of the base 1. Because the adjusting block 4 is threadedly engaged with the threaded column 3 and the threaded column 3 is restricted from rotating by the limiting groove and the limiting block 100, the threaded column 3 can be raised and lowered linearly, flexibly adjusting the height of the insect-attracting lamp 7 and the electric grid 6 to suit the chestnut tree and the area where pests are active. When the insect-attracting lamp 7 is turned on, it attracts phototactic pests to approach and kills them when they come into contact with the electric grid 6. When it is necessary to clean the electric grid 6, the operator holds the first handle 11 of the mounting frame 10 and moves it up and down along the guide rail 9. During the up and down movement of the mounting frame 10, the rotating motor 12 is started, and the drive block 16 drives the movable ring 13 and the cleaning brush 14 to rotate and scrape off the insect carcasses through the rubber ring 15.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
