Description

Technical Field

[0001] The utility model relates to the technical field of pest control, in particular to a portable insect killer for killing soil insect pupae. Background Art

[0002] Among tea plant pests, lepidopteran pests (young caterpillars, commonly known as caterpillars) chew on the tender buds and leaves of tea leaves, often devouring the entire canopy of tea plants and having the greatest impact on tea production. Current prevention methods for these caterpillars primarily rely on spraying biocontrol bacteria and biological pesticides to control infestations, but this approach is only a post-event approach. Another common approach is to use LED insect killers to attract and kill the pests. However, both spraying biocontrol bacteria on the canopy of tea plants and using insect killers to kill pests have certain shortcomings.

[0003] The life cycle of Lepidoptera insects consists of four stages: eggs, larvae, pupae, and adults. Among them, the stage that poses the greatest threat to tea trees is the larval stage. Biocontrol bacteria are mainly used for prevention and control of the larval stage. At this time, a large number of eggs have hatched into larvae, and their distribution range is wide, so the effectiveness of applying biocontrol bacteria is difficult to guarantee. Insecticidal lamps are mainly used for prevention and control of the adult stage. Insecticidal lamps can kill emerged adults and reduce their chances of mating and laying eggs. However, while killing pests, insecticidal lamps will also indiscriminately kill a large number of beneficial insects.

[0004] A Chinese patent discloses a portable insect killer for killing soil insect pupae (authorization publication number CN209251508U). This patented technology allows a control lever to be dragged to drive an insect killer sleeve to roll on the soil surface. The weight of the insect killer sleeve allows the insect-killing spikes on the insect killer sleeve to penetrate the soil surface, piercing the pupae on the soil surface, thereby killing the pupae. The portable insect killer has a compact structure, a reasonable design, and is easy to carry. It can kill pests in the pupal stage, has a significant insecticidal effect, reduces subsequent insect population density, and helps alleviate the impact of caterpillars on tea yield and quality.

[0005] However, it has certain disadvantages: although the weight of the insect-killing sleeve itself can drive the insect-killing nails into the soil, due to the existence of soil resistance, the insect-killing sleeve is very difficult to push on the ground, and the insect-killing nails cannot be fully inserted into the soil, that is, the insect pupae in deeper positions cannot be killed. Utility Model Content

[0006] The purpose of the utility model is to provide a portable insect killer for killing soil insect pupae, so as to solve the problems raised in the above background technology.

[0025] Universal wheels 4 facilitate the movement of the insect killer on land;

[0026] The pull rod 2 facilitates dragging the base 1;

[0027] The insect-killing nail 6 is a spike-shaped structure with the spike end facing downwards, which is used to be inserted into the soil and inserted into the insect pupae, thereby effectively killing the insect pupae;

[0028] The initial state of the slide plate 10 is at the highest position, and the pressing plate 5 is also at the highest position;

[0029] The motor 13 is equipped with a brake, that is, its motor shaft cannot rotate after power is cut off, and it is used to drive the disc 14 to rotate clockwise; the motor 13 is a variable frequency motor, and its speed is adjustable;

[0030] The second teeth 15 are distributed on one third of the side surface area of ​​the disc 14;

[0031] When the second teeth 15 engage with the first teeth 12 on the right side, the slide 10 is driven downward. When the second teeth 15 engage with the first teeth 12 on the left side, the slide 10 is driven upward and downward, thereby driving the slide 10 to rise and fall back and forth. Moreover, when the second teeth 15 at one end are about to disengage from the first teeth 12 on one side, the second teeth 15 at the other end are about to engage with the first teeth 12 on the other side, thereby forming a smooth cooperation, so that the slide 10 will not fall suddenly.
