Description

Technical Field

[0001] The utility model relates to the technical field of pest killing, in particular to a device for killing pests in a granary. Background Art

[0002] During the storage process of grain in granaries, due to environmental factors and other factors, pests are prone to breed. Pests will destroy and contaminate grain. Therefore, it is necessary to capture and kill the pests in the granary.

[0003] The prior art generally uses a pest killing device to kill pests in a granary. The pest killing device includes an insect trapping cage, which is provided with an insect attracting lamp and an attractant ball, and a pest collecting bin is provided below the insect trapping cage. The insect attracting lamp is used to attract pests to the insect trapping cage, and the surface of the attractant ball is sticky, so that the attractant ball can stick to the pests and prevent them from escaping. However, during long-term use, the attractant ball of the pest killing device will have many pests attached to the surface, which is not easy to clean and will affect the subsequent adhesion and capture of pests entering the insect trapping cage. Since the pests cannot be stuck, the attractant ball can only temporarily trap the pests that enter the insect trapping cage, and the pests are prone to escape from the insect trapping cage. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a device for catching and killing pests in a granary.

[0005] The technical solution of this utility model is as follows:

[0006] A device for killing pests in a grain bin comprises an outer sleeve arranged vertically, connected to the inner wall of the grain bin through a supporting mechanism, an insect collecting cylinder arranged at the lower end thereof, insecticide arranged in the insect collecting cylinder, and the lower part of the outer sleeve inserted into the grain pile;

[0007] An inner sleeve is inserted into the outer sleeve, and the inner sleeve can rotate. The cylinder body of the outer sleeve is provided with a plurality of first insect holes, and the cylinder body of the inner sleeve is provided with a plurality of second insect holes corresponding to the first insect holes. A lower killing component is provided at the lower end of the inner sleeve, including an inverted cone-shaped high-voltage power grid and an insect attractant placement platform located on one side thereof, and a first opening connected to the insect collecting cylinder is provided at the bottom of the inverted cone-shaped high-voltage power grid.

[0008] The crawling pests enter the inner sleeve and crawl towards the attractant. They will pass through the inverted cone-shaped high-voltage electric grid, which will directly kill the crawling pests. The conical surface of the inverted cone-shaped high-voltage electric grid can reduce the accumulation of pests, and some pests can also fall into the insect collecting tube through the first opening for killing or collection.

[0009] The lower killing component can only kill crawling pests in the grain pile, but cannot kill flying pests on the surface of the grain pile. For this reason, an upper killing component is provided at the upper end of the inner sleeve. The upper killing component includes an insect attractant lamp and a second high-voltage power grid arranged outside the insect attractant lamp. The insect attractant lamp is used to lure flying pests, and the flying pests are killed by the second high-voltage power grid. The killed pests can fall into the inner sleeve or the insect collecting tube.

[0010] To prevent food from entering the inner sleeve through the channel, or to be able to adaptably adjust the channel size formed by the first wormhole and the second wormhole according to the size of crawling pests, the interleaving area of ​​the first wormhole and the second wormhole is set to be able to change as the inner sleeve rotates relative to the outer sleeve.

[0011] The corresponding positions of the first wormhole and the second wormhole can be adjusted by rotating the inner sleeve to achieve the adjustment of the channel size. The single second wormhole is in the shape of a teardrop, and the diameter decreases along the circumferential direction of the inner sleeve. The second wormhole can increase the adjustment range of the channel size and is suitable for crawling pests of different sizes to pass through.

[0012] The specific structure of the second wormhole is that the second wormhole includes a large circular hole and a small circular hole located in the same horizontal plane and connected to each other, and the first wormhole is larger than the large circular hole.

[0013] In order to reduce the risk of pests caught by the upper killing component falling onto the inverted cone-shaped high-voltage power grid and causing accumulation, an inverted cone-shaped guide cylinder coaxial with its axis is provided on the inner wall of the inner sleeve, a second opening is provided at the bottom, and the projection of the second opening is located within the first opening. Flying pests falling from the upper killing component will fall directly into the insect collecting cylinder for collection under the guidance of the inverted cone-shaped guide cylinder.

[0014] The inner sleeve needs to be fixed with the outer sleeve after rotation to avoid misalignment between the first worm hole and the second worm hole, which affects the entry of pests. The inner sleeve is connected with the outer sleeve through a locking mechanism, and the locking end of the locking mechanism can lock the inner sleeve with the outer sleeve.

[0015] Regarding the circuit connection of the second high-voltage power grid below, a wire groove is vertically opened on the inner wall of the inner sleeve, and a conductor is arranged in the wire groove. The conical high-voltage power grid and the second high-voltage power grid are electrically connected through the conductor. The conductor is installed in the wire groove and does not leak out. This not only facilitates the circuit connection of the second high-voltage power grid, but also reduces the phenomenon of damage by pests on the inner side of the inner sleeve due to leakage.

[0016] In order to quickly clean the pests and pesticides in the insect collecting barrel, the insect collecting barrel is detachably connected to the lower end of the outer sleeve, and the lower end surface of the insect collecting barrel is an inverted conical surface, which makes it easy to quickly insert the outer sleeve into the grain pile.

[0017] The inverted cone-shaped high-voltage grid is not convenient to be directly connected to the inner sleeve. To facilitate the installation of the cone-shaped high-voltage grid, the inverted cone-shaped high-voltage grid is detachably connected to the lower end of the inner sleeve through a connecting piece. The connecting piece is an annular sleeve. The lower end of the annular sleeve is fixedly connected to the upper end of the cone-shaped high-voltage grid, and the outer surface of the annular sleeve is threadedly connected to the inner wall of the inner sleeve.

[0018] The beneficial effects of the present invention are:

[0019] The lower part of the outer sleeve can be inserted into the grain pile, and the insect attractant arranged at the lower end of the inner part attracts the crawling pests in the grain pile to enter the lower killing component through the first insect holes in different directions. The insect attractant placement table is placed on one side of the inverted cone-shaped high-voltage power grid. When the pests crawl to the insect attractant, they will pass through the inverted cone-shaped high-voltage power grid. The inverted cone-shaped high-voltage power grid is energized, and the pests are directly killed by the high-voltage current, and the pests will not escape.

[0020] The inner sleeve can rotate on the outer sleeve, and when the first insect hole and the second insect hole correspond one to one, a channel for pests to enter the inner sleeve can be formed. The size of the channel can be changed by rotating the inner sleeve to prevent food from entering the inner sleeve. The size of the channel can also be adjusted according to the size of the crawling pests, and can be suitable for killing different types of pests.

[0021] The inverted cone-shaped high-voltage power grid is arranged in an inverted cone shape, which can reduce the accumulation of pests after killing, and the living pests and / or killed pests can fall into the insect collecting cylinder filled with insecticide through the first opening to be killed or collected.
