Description

Cyclone-sealed air-absorption spectral light excitation-induced locust trapping device

technical field

The invention belongs to the technical field of modern physical agricultural engineering equipment, and in particular relates to a cyclone-sealed air-absorption spectral light excitation-induced locust trapping device.

Background technique

Modern physical agriculture is an emerging discipline that combines agriculture and physics. It belongs to high-input and high-output equipment-type, facility-type, and craft-type agriculture. It is a new agricultural production technology system that uses physical factors with biological effects to regulate agricultural production. The environment, and biophysical factors as the control object, prompts traditional agriculture to gradually get rid of the dependence on chemicals such as fertilizers, pesticides, and antibiotics, as well as the constraints of the natural environment, and requires technology, equipment, and animals and plants to be highly related to maximize agricultural production. Improve the ecological environment for agricultural development, reduce the use of chemical fertilizers and pesticides, and promote the sustainable development of agriculture. Therefore, in the context of my country's accelerated transformation from traditional agriculture to modern agriculture, to realize the in-depth transformation from chemical agriculture to physical agriculture, it is important to replace the pest control technologies in farmland, grassland and even forests that rely mainly on chemical pesticides.

At present, the locust plague is the most widespread and most damaging pest in my country and even in the world. After the locust plague breaks out, it can cause devastating damage to agriculture, animal husbandry and even forestry. In recent years, there have been records of locust plague outbreaks in most provinces of our country, especially in the northern grassland areas, where locust plagues have broken out year after year, and the control of locust plagues has reached an urgent level. The control of locust disasters usually adopts the method of spraying chemical pesticides to kill them, which causes a large amount of pesticides to immerse into the natural environment year after year, and also causes harm to other beneficial insects and birds, and also kills a large number of natural enemies of locusts. , which weakens the ability of natural regulation of the environment.

According to reports, even the large-scale mechanized pesticide application technology of electrostatic micro-spraying developed in recent years can only reduce the amount of pesticide applied by one-third. Therefore, chemical treatment will inevitably cause environmental pollution and even ecological damage.

The biological agent method shows an environmentally friendly effect in the control of locust disasters, but its drug effect is slow, and for the control of high-density locusts, it is still necessary to use chemical methods first, and good results can only be produced after suppressing the population density to medium density. governance effect.

Mechanized suction and capture technology (CN 2092865U, CN 2105840U) has appeared in the prevention and control of explosive locust disasters. The larvae of locust outbreaks - locust gnats are captured and controlled, and they play a role in the physical control of grassland locusts. However, the application of this wind-driven and mechanized method of catching locusts to uneven tidal flats and hilly areas and farmland areas that are not conducive to mechanical access will be limited.

Microwave electromagnetic field radiant insecticide (CN 2534824Y), relying on the vehicle-mounted adjustable frame and microwave radiator, is aimed at various pests for microwave radiation heating and killing, and can be used to kill locusts and other agricultural, forestry and household pests. This method achieves non-toxic extermination of locusts with the help of microwave electromagnetic energy, but the electromagnetic pollution and environmental safety issues of microwaves are worth noting.

Biophotonic spectrum photothermal mutagenesis killing technology, with the help of mechanically loaded large-area array laser killers, implements targeted photothermal mutagenesis killing of high-density locusts. However, it is easy to kill locusts when the laser beam irradiates their heads. The implementation of laser arrays makes it difficult to realize automatic control, and locusts are sensitive to danger signals and fly away, which restricts the realization of laser field killing locusts.

In recent years, the research work on photoelectric induced locust trapping and control technology has been widely carried out (application numbers 0310113391.X, 0410096643.7, 0420116184.X, 200310113391.X, 201320159442.1), which integrates the phototaxis induction aggregation of nocturnal locusts, the activity ability of locusts The three technologies of excitation and locust slipping and trapping are integrated to achieve the dual effects of directly reducing insect population density and utilizing biological resources. The combination of mechanical sliding and trapping can realize the induced trapping management of explosive high-density locusts. However, the diurnal and nocturnal locust's phototaxis visual behavior is difficult to stimulate, the phototaxis visual sensitivity spectrum is difficult to define, the complexity of phototaxis-induced aggregation behavior, and the slide plate used has multiple wrinkles to achieve the slip trap effect. However, the height of the trapping box is increased, which is not conducive to the regulation and realization of the phototaxis trapping behavior of locusts under the photoelectric induction effect. Therefore, it is necessary to take effective measures to effectively solve the problems of locust visual stimulation induction and capture.

The working principle of the present invention is: aiming at the spectral energy requirements of locust phototaxis vision excitation and induction of nighttime habitat disasters, using stroboscopic purple light and ultraviolet light with strong particle energy to stimulate insect visual system characteristics, locust phototaxis vision is effectively stimulated and sensitive. The phototaxis effect formed by absorbing the light energy of orange light and the sensitive spectrum energy in purple light and ultraviolet light, under the excitation and induction of strong strobe purple light, orange light, and ultraviolet light coupling light energy, stimulates the phototaxis visual response of distant locusts orientation, induce the formation of phototaxis aggregation effect of locusts at different distances, and regulate the phototaxis uplight trapping behavior of nearby locusts. During the phototaxis process of locusts, stroboscopic purple light, orange light, and ultraviolet light coupled with light energy stimulate phototaxis and visual movement of locusts, and induce mutations in phototaxis physiological responses of locusts, which will lead to phototaxis direct flight and bouncing of locusts Behavior of lighting up or phototaxis crawling and gathering around the box (the height of the box meets the requirements of bouncing lights due to the setting of the inclination angle of the skateboard). Due to the determination and formation of the wind speed of the rotating blade, the following situations occur in the process of catching the light source when the locust flies directly toward the light and bounces on the light: First, the locust without behavior adjustment, under the action of the blade rotating, hitting, dropping and transporting, Or be thrown down on the surroundings of the box and on the skateboard, or be rolled onto the skateboard within a distance ≥D; second, the behavior-adjustable locust will land on the skateboard within a distance of 0-D to form a visual behavior of condensing the lamp, and the ultraviolet light Alternate stimulation of the locust's vision with on and off, and superimposed reinforcement of strobe purple and orange light, or repeat the behavior of the above situation, or slide the phototaxis adjustment to within a distance ≥D. At the same time, the distance d between the bottom end of the blade rotating system and the box, and the axially downward wind speed of the rotating blades can effectively form the wind speed traction and sealing effect on the locusts on the slide with a distance ≥ D, and accelerate the realization of slip capture. The locusts falling on the sliding board fall into the guiding channel, slide under the effect of the falling, and fall into the trapping box through the filter self-locking mechanism. In addition, the locusts gathered by phototaxis and dropped to the surroundings of the box are under the action of the negative pressure wind force of the negative pressure fan and the air suction through the fluke mouth, and enter the insect collection and separation chamber through the fluke channel for sedimentation and separation. In this way, through the stimulation of the locust phototaxis vision by the spectral light energy, the phototaxis-induced aggregation and lighting behavior of the locusts are effectively formed, and the regulation of the spectral light energy at the light source and the stimulation, blowing, transporting and sealing effect of the rotating blade wind are effective. It solves the difficult problem of locust phototaxis and lamp phototaxis trapping behavior, and effectively solves the problem of trapping phototaxis crawling locusts and "lower lamp" locusts through air suction.
