Description

Technical Field

[0001] The utility model relates to the technical field of insect killers, in particular to an insect killer for plant protection. Background Art

[0002] The biggest hazard to plant growth is pests. However, as people's environmental awareness increases, more and more people are demanding safe and effective pest control methods to reduce spraying and protect the environment. Among them, insect killer lamps are a more commonly used device. They use the phototaxis of mosquitoes, fruit flies, leafhoppers and other pests, and then use high-voltage power grids to electrocute the above pests. In order to achieve a better insect killing effect, insect killer lamps are generally installed at a position slightly higher than the height of the plants.

[0003] The existing patent announcement number: CN217012425U proposes an insect-killing device for plant protection, including an insect-killing box, the outer circumferential wall of the insect-killing box is provided with an insect-attracting opening, the interior of the insect-killing box is provided with an insect-attracting lamp, and the inner top surface of the insect-killing box is fixedly installed with an electric grid. However, in this device, "the inner top surface of the insect-killing box is fixedly installed with an electric grid", when the electric grid kills pests, some of the dead insects will be retained in the mesh of the electric grid. If it is not cleaned for a long time, it will affect the killing effect of the electric grid, and the dead insects retained in the mesh will easily rot, causing bacteria to breed, affecting the insect-killing effect and service life of the insect-killing device. In addition, the existing insect-killing devices are usually hung on plants, which are not suitable for use on short and delicate plants, and the installation is relatively cumbersome.

The end of the inclined rod 15 away from the hemispherical block 14 is in a conical structure. The height of the insecticide mechanism 2 can be adjusted by inserting the inclined rod 15 into the ground, or digging a pit equal to the size of the inclined rod 15 on the land of the plants to be protected, and then inserting the inclined rod 15 into the pit.

[0031] like Figure 2 and Figure 3 As shown, the rotating ring 31 and the fixed ring 24, and the rotating ring 31 and the connecting ring 11 are respectively rotationally matched through the rotation positioning mechanism 4. In other embodiments of the utility model, the outer side wall of the fixed ring 24 and the outer side wall of the connecting ring 11 can be provided with a toroidal roller bearing, and the inner side wall of the rotating ring 31 is connected to the outer side wall of the toroidal roller bearing, so that the rotating ring 31 can be rotated with the fixed ring 24 and the connecting ring 11.

Under the action of the spring 43, the insertion rod 41 can be pushed into the third annular groove 7, thereby limiting the axial displacement of the fixing ring 24 and the connecting ring 11, so that the cleaning mechanism 3 and the insecticide mechanism 2 and the telescopic base 1 can be quickly disassembled and assembled, and their rotational coordination can be ensured.

[0034] When in use, the inclined rod 15 is inserted into the ground, or a pit equal to the size of the inclined rod 15 is dug on the land of the plant to be protected, and the inclined rod 15 is inserted into the pit and fixed. The telescopic rod 13 is used to adjust the height of the insect killing mechanism 2. When a strong wind blows and the fan blades 32 rotate, the fan blades 32 will eventually drive the insulating brushes on the vertical rods 33 to clean the dead bodies of the pests on the inside and outside of the annular grid 23. Since the connecting ring 11 on the telescopic base 1 is in a circular ring shape, some pests can enter the annular grid 23 from the position of the connecting ring 11. The vertical rods 33 and insulating brushes are arranged on the inside and outside of the annular grid 23 to achieve a better cleaning effect; the fixed ring 24 and the rotating ring 31, and the connecting ring 11 and the rotating ring 31 can be quickly installed by pulling the insertion rod 41.
