Description

Technical Field

[0001] The invention relates to the forestry field, and in particular to a forestry pest trapping device. Background Art

[0002] The biggest natural enemy of trees during their growth is various pests. Pests invade or parasitize trees, causing a series of abnormal changes in the plants' morphology, organization or physiology, leading to poor growth and development, reduced yield and quality, and even causing plant death and ecological environment deterioration. In order to better ensure the growth of plants, people use various trapping devices to help trees remove pests, thereby achieving early warning and prevention of tree pests.

[0003] When trapping pests, they are usually attracted by ultraviolet light and insect lamps, or by chemical attractants. Current trapping devices usually trap pests into collection net bags, which need to be cleaned regularly by humans. However, in the summer when pests have strong reproductive capacity, the collection box will become full in a very short time, which requires frequent cleaning of the collection box. In addition, the current trapping device core needs to be regularly added with attractants every 1-2 months.

[0019] Working principle: When the present invention is used, the hanging structure 1 is placed at the pest catching location, and then the trapping structure 2 is hung on the hook 37 of the hanging structure 1 through the hanging ring 5. At this time, the surrounding harmful flying insects are attracted by the attractant on the water-absorbing sponge 39 and fly to the attractant core installation barrel 12. The attractant on the water-absorbing sponge 39 is dispersed through the odor dissipation holes 13 on the attractant core installation barrel 12, thereby achieving the purpose of attracting harmful flying insects. The harmful flying insects flying to the attractant core installation barrel 12 gather in the conical tube 8 and enter the net bag 22 through the conical tube 8. The flying insects entering the net bag 22 are difficult to fly out through the small opening at the bottom of the conical tube 8. In this way, the trapped pests entering the net bag 22 die and dry under the action of the natural wind outside.

[0020] The PLC controller 34 controls the operation of the trapping light 15 and the electric telescopic rod 11 at a fixed time, so that the trapping light 15 is lit at night and turned off during the day, and the telescopic end of the electric telescopic rod 11 is intermittently extended and retracted once. When the trapping light 15 is lit at night, the pests will be attracted to the conical tube 8 by the light, so that more pests will gather in the conical tube 8, thereby improving the trapping effect. Whenever the telescopic end of the electric telescopic rod 11 is extended and retracted once, during the extension process of the telescopic end of the electric telescopic rod 11, the conical block 30 pushes the net bag 22 from the bottom end of the net bag 22, so that the net bag 22 turns over in an inverted cone shape. As the telescopic end of the electric telescopic rod 11 is extended, the inverted cone-shaped net bag 22 pulls the fixing ring 21 to move upward, and at this time the first rack 20 When the second rack 25 moves downward, the second rack 25 is driven in the opposite direction by the gear 24 to move downward. When the second rack 25 moves downward, the second cylinder 23 is synchronously driven to move downward, so that the top of the second cylinder 23 is separated from the bottom of the first cylinder 7. At this time, as the top of the second cylinder 23 is separated from the bottom of the first cylinder 7, a gap is opened between the second cylinder 23 and the first cylinder 7. At this time, as the net bag 22 turns over in an inverted cone shape, the pests in the net bag 22 roll off the net bag 22 turned over in an inverted cone shape, and are discharged from the gap opened between the second cylinder 23 and the first cylinder 7, thereby achieving the purpose of automatically cleaning the net bag 22. At the same time, as the telescopic end of the electric telescopic rod 11 is extended, the conical block 30 The conical tube 8 is pushed upward from the bottom end thereof. As the conical tube 8 rises, the lure core installation barrel 12 moves upward synchronously. At this time, the top end of the installation rod 38 in the lure core installation barrel 12 pushes the blocking plate 43 upward through the conical push rod 42, so that the sealing ring 44 at the bottom of the blocking plate 43 is separated from the bottom end of the medicine storage box 40. At this time, the trapping agent in the medicine storage box 40 flows to the installation rod 38 through the discharge hole 41. The trapping agent flowing to the installation rod 38 is absorbed by the water-absorbing sponge 39, thereby achieving the purpose of automatically adding the trapping agent to the water-absorbing sponge 39. During the retraction process of the telescopic end of the electric telescopic rod 11, the conical block 30 is synchronously lowered and reset along with the telescopic end of the electric telescopic rod 11. At this time, the net bag 22 is pulled downward by the conical block 30 and becomes back Initial shape, in the process of the net bag 22 returning to the initial shape, the first rack 20 descends and resets under the action of the second spring 29, and the second rack 25 moves upward and resets through the gear 24 during the process of the first rack 20 descending and resetting, and the second rack 25 moves upward and resets during the process of synchronously driving the second cylinder 23 to reset upward, so that the top end of the second cylinder 23 fits with the bottom end of the first cylinder 7. At the same time, the conical cylinder 8 is reset under the action of the first spring 10, and as the conical cylinder 8 descends and resets, the top end of the mounting rod 38 separates from the conical top rod 42, and the sealing disk 43 descends and resets under the action of the third spring 47, and the sealing ring 44 at the bottom re-blocks the discharge hole 41 to prevent the attractant in the medicine storage box 40 from flowing out.
