Description

Technical Field

[0001] This utility model belongs to the field of corn pest and disease control technology, and in particular relates to a water-saving and quantitative pesticide application soil device for controlling fall armyworm. Background Technology

[0002] The fall armyworm is the number one pest in my country. Its larvae mainly hide in the corn cob and leaf area and damage corn. In order to control the fall armyworm larvae hiding in the corn cob and leaf area and causing damage, it is necessary to apply pesticides to the corn cob and leaf area regularly.

[0003] Currently, pesticide application mainly involves spraying with diluted water. This is inconvenient and difficult to implement in water-scarce and labor-scarce agricultural areas in my country. Furthermore, many pesticide solutions (especially powdered pesticides) have poor systemic absorption, often resulting in the solution "running, leaking, dripping, and seeping" into the soil without adhering to the stems, leaves, and heart leaves of corn crops. This prevents effective control of fall armyworm pests, leading to poor pest control, soil pollution, and increased pesticide usage. Traditional pesticide dusting machines and electric dusters, on the other hand, have high investment costs and are prone to pesticide drift and increased pesticide usage. Utility Model Content

[0004] This invention provides a water-saving, quantitative pesticide application device for controlling fall armyworm, aiming to solve the problems mentioned in the background art of using pesticides for fall armyworm control, such as high water consumption, large pesticide dosage, poor control effect, and increased pesticide residues and pollution in the soil.

[0005] To solve the above problems, this utility model is implemented as follows: a water-saving and quantitative pesticide application device for controlling fall armyworm, comprising: a double-capped application bottle for holding pesticide-coated soil for controlling fall armyworm, the double-capped application bottle including an inner cap and an outer cap, both the outer cap and the inner cap being disposed on the double-capped application bottle; a pesticide outlet on the outer cap of the double-capped application bottle for discharging and applying pesticide-coated soil for controlling fall armyworm, the outlet being a circular hole with a diameter of 3.5 cm; a baffle fixedly installed on the inner cap, the distance between the baffle and the outer cap being at least 5 cm; two openings on the inner cap for allowing the pesticide-coated soil for controlling fall armyworm to flow smoothly within the double-capped application bottle; and a steel ball placed inside the double-capped application bottle, the steel ball being located between the inner cap and the outer cap, the steel ball having a diameter of 4 cm.

[0006] Preferably, the amount of pesticide applied by the steel ball when it is used to shake and apply pesticide to the outlet of the double-capped application bottle.

[0007] Preferably, the double-capped application bottle is a wide-mouth plastic bottle containing the inner cap and the outer cap.

[0008] Preferably, the dispensing port is circular and its diameter is smaller than that of the steel ball.

[0009] Preferably, the baffle and the opening are at least 5 cm away from the outer cap of the double-cap application bottle and the dispensing port on the outer cap, to ensure that the steel ball can move between the baffle on the inner cap and the outer cap, and can promptly block / open the dispensing port.

[0010] Preferably, the opening is formed on both sides of the baffle strip on the inner cover, and the diameter of the baffle strip from the inner wall of the double-capped application bottle is less than 4 cm than the diameter of the steel ball, so as to ensure that the medicine soil in the double-capped application bottle flows smoothly in the bottle, while preventing the steel ball from falling into the bottle space below the inner cap.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a water-saving, quantitative pesticide application soil device for controlling fall armyworm, such as... Figure 1-4 As shown, the water-saving and quantitative pesticide application device for controlling fall armyworm includes: a double-capped application bottle 1, which is used to hold pesticide-coated soil for controlling fall armyworm. The double-capped application bottle 1 includes an inner cap and an outer cap, both of which are located on the double-capped application bottle 1; a pesticide outlet 2 opened on the outer cap of the double-capped application bottle 1, which is used to discharge and apply pesticide-coated soil for controlling fall armyworm, and the pesticide outlet 2 is a circular hole with a diameter of 3.5 cm; a baffle 3 fixedly installed on the inner cap; the distance between the baffle 3 and the outer cap is at least 5 cm; two openings 4 opened on the inner cap, which are used to allow the pesticide-coated soil for controlling fall armyworm to flow smoothly in the double-capped application bottle 1; and a steel ball 5 placed in the double-capped application bottle 1, which is located between the inner cap and the outer cap, and the steel ball 5 has a diameter of 4 cm.

[0022] In this embodiment, the innovative design of the dispensing port 2, the baffle 3, and the two openings 4 is to ensure that the diameter of the steel ball 5 is smaller than the diameter of the dispensing port 2 and larger than the distance between the baffle 3 and the inner wall of the double-capped application bottle 1. This allows for limited movement of the steel ball between the outer cap and the baffle, so that the dispensing port 2 can be opened / sealed in time when applying the medicated soil, and the amount of medicated soil applied each time can be quantitatively controlled (i.e., about 5-10 grams of medicated soil per shake). The double-capped application bottle 1 is a commercially available 1-liter (1000ml) wide-mouth round double-capped plastic bottle. The height of the double-capped application bottle 1 is about 14cm, the inner diameter of the double-capped application bottle 1 is about 11.1cm, the width of the baffle 5 is about 4.5cm, the opening 6 is a semi-circle with a maximum diameter of about 3.5cm, the diameter of the steel ball 7 is about 4cm, the steel ball 5 is made of stainless steel, and the dispensing port 3 is a circle with a diameter of about 3.5cm.

[0023] Preparation and coarse grinding of pesticide-soil mixture: Mix the insecticide with 20kg-30kg of soil according to the ratio and dosage specified on the pesticide label (the amount depends on the crop variety and density planted in the field; for example, if the corn planting density is 4000-5500 plants per acre, approximately 20kg-30kg of soil is needed). Stir well to form a mixture with a diameter of approximately 1.5cm or less. Prepare the pesticide granules (note that if the insecticide is a liquid, the mixed pesticide soil should be dried before use). Filling the pesticide soil into the bottle: Take approximately 1 kg of dried pesticide soil prepared according to the usage ratio of the commercial pesticide and fill it into a wide-mouth double-cap application bottle 1. When applying the pesticide to corn, the applicator should wear gloves and use one hand to aim the outlet 3 on the double-cap application bottle 1 at the corn leaf core. Shake the double-cap application bottle 1 once to pour out a certain amount of pesticide soil into the corn stem and leaf core. The number of shakings depends on the actual amount of pesticide soil needed based on the severity of the corn pest infestation. The calculation of the amount of pesticide soil poured out with each shaking is based on the formula: Q = S × V, where Q is the amount of pesticide soil poured out; S is the cross-sectional area of ​​the double-cap application bottle 1 = л × r 2 =Inner radius of double-capped application bottle 1 squared × 3.14 = 96.72 (square centimeters); V is the actual measured volume of medicated soil that can be poured out of the double-capped application bottle 1 in about 0.1 seconds after one shaking (swinging) = approximately 0.04 cubic centimeters on average (considering the soil density is about 2.7 g / cubic centimeter), then 0.04 cubic meters of medicated soil is about 0.104 grams; that is: each time the double-capped application bottle 1 is shaken, about 0.104 grams of medicated soil can be poured out, that is, V = 0.104 g g / 0.1 seconds·each application; Therefore: the amount of medicated soil applied by the double-capped application bottle 1 with each shaking Q = S × V = 96.72 / cm2 × 0.104 g g / 0.1 seconds·each application = 10.06 ≈ 10 g g / 0.1 seconds·each application.

[0024] Repeat the above steps on other farmland plots to complete the application of pesticide-soil to all crops in the area. Ten days after the first application of pesticide-soil to the farmland, conduct a field inspection. If pests are still observed hiding in the core leaves of crops such as corn, a second application of pesticide-soil should be carried out. After the pesticide application is completed, pour out and empty the pesticide-soil residue in the double-capped pesticide bottle 1, wash the double-capped pesticide bottle 1, dry it, and prepare it for the next use.

[0025] The entire device can operate around the clock: Traditional pesticide spraying for controlling fall armyworm uses water as a pesticide dilution carrier, which can easily lead to pesticide drift and dispersion hazards during spraying. Therefore, pesticide spraying is generally required to be carried out in the field in the morning and after sunset. This device uses soil as a pesticide carrier and achieves precise application of pesticides into the gaps between corn stalks and leaves, with virtually no risk of drift and pollution. In water-scarce mountain cornfields, pesticide application and soil pest control can be carried out at any time of day (mainly during the day).

[0026] The steel balls used in this device have a density of 7.85 g / cm³. 2 It is more than 3 times denser than soil (approximately 2.7 g / cm³). 2 In a static state, the steel ball 7, with a density and weight three times that of the surrounding soil, can completely block the outlet 3, preventing the pesticide from overflowing from the outlet 2 of the double-capped pesticide bottle 1 during application. During each shaking during application, the steel ball 5 briefly (about 0.1 seconds) leaves the outlet 2, allowing a measured amount of pesticide (about 5 to 10 grams each time) to be poured out from the outlet 2, acting on the core of the corn stalk and leaves. This ensures a scientifically reasonable dosage of pesticide and a slow release of the killing effect, effectively killing pest larvae in the crevices of the corn stalk and leaves. The movement range of the steel ball 5 is restricted to the area between the baffle 3 on the inner cover and the outer cover. This prevents excessive pesticide residue from entering the small space between the inner and outer covers of the double-cover application bottle 1, which would affect the opening / closing of the outlet 2 on the outer cover. It also limits the free movement of the steel ball 5 within the double-cover application bottle 1, thus reducing the quantity and efficiency of the pesticide residue released through shaking. This results in a "quantitative" application of pesticide residue: approximately 8-10g of pesticide residue can be released with one manual shake, and approximately 16-20g with two manual shakes. This ensures a scientifically reasonable dosage of pesticide residue and a slow release of the killing effect, effectively achieving the "water-saving and quantitative" effect in controlling fall armyworm larvae in the crevices of corn stalks and leaves.

[0027] The entire device can be used to apply pesticides to control fall armyworm on corn. It also solves the problem that most corn in our province is planted in water-scarce mountainous areas, where there is a lack of water for pesticide preparation. In addition, the conventional application of non-water-soluble powdered and oily pesticides has poor control effects on pest larvae that remain and hide in the crevices of corn stems and leaves and the heart leaves. It achieves the goal and effect of stable and controllable "precise application and slow-release pesticide for enhanced efficacy".

[0028] In a further preferred embodiment of this utility model, the steel ball 5 is used to shake and release the amount of medicine soil to open / seal the outlet 2 inside the double-capped medicine bottle 1.

[0029] In a further preferred embodiment of this utility model, the double-capped application bottle 1 is a wide-mouth plastic bottle containing the inner cap and the outer cap.

[0030] In this embodiment, the double-capped application bottle 1 is a wide-mouth plastic double-capped bottle, which is simple and convenient to manufacture.

[0031] In a further preferred embodiment of this utility model, the medicine outlet 2 is circular and its diameter is smaller than that of the steel ball 5.

[0032] In this embodiment, the medicine outlet 2 is circular to facilitate the discharge of medicine and soil.

[0033] In a further preferred embodiment of this utility model, the baffle 3 and the through-hole 4 are at least 5 cm away from the outer cover of the double-capped application bottle 1 and the medicine outlet 2 opened on the outer cover, so as to ensure that the steel ball 5 can move between the baffle 3 on the inner cover and the outer cover and can block / open the medicine outlet 2 in time.

[0034] In a further preferred embodiment of this utility model, the opening 4 is a semi-circular hollow channel formed on both sides of the baffle 3 on the inner cover, and the maximum distance between the two sides of the baffle 3 and the inner wall of the application bottle 1 is less than the diameter of the steel ball 5 by 4 cm, so as to ensure that the medicine in the double-cap application bottle 1 flows smoothly on both sides of the inner cap, while preventing the steel ball 5 from falling into the space between the inner cap and the bottom of the application bottle.

[0035] In summary, compared with related technologies, this device can be used to apply pesticides to the corn cob leaves to control fall armyworm. It also solves the problems of corn being mostly planted in water-scarce mountainous areas of our province, where there is a lack of water for pesticide preparation, and the difficulty for pesticide liquid to remain in the crevices of corn stems and leaves and the cob leaves, thus affecting the control effect on pest larvae hiding in the crevices of the cob leaves. It can achieve stable and controllable "precision application and slow-release pesticide for enhanced efficacy".
