A slit-hole granule dispensing machine with a medicine proportioning function

Abstract

This utility model discloses a slit-hole granular pesticide dispenser with a drug mixing function, including a housing. The mixing tank is equipped with a pulverizing mechanism for crushing granular pesticides. Through the design of the pulverizing mechanism and the air supply and delivery mechanism, this utility model can crush the mixed insecticide, desiccant, and attractant. The crushed pesticide, desiccant, and attractant are crushed and mixed. When the crushed pesticide is transported through the delivery pipe, the air supply and delivery mechanism can mix the crushed pesticide with a high-speed airflow to form a gas-solid two-phase flow. This allows the pesticide to quickly penetrate the narrow gaps in the insect nest through the delivery pipe and reach the core area, overcoming the shortcomings of traditional mechanical delivery which is difficult to penetrate deeply. In addition, the crushed pesticide particles are smaller and have better diffusion after mixing with the gas, which can evenly cover the inside of the nest, increasing the probability of contact between the insecticide and the pest. At the same time, the synergistic effect of the desiccant and attractant is enhanced, prolonging the duration of the pesticide effect.

Description

Technical Field

[0001] This utility model relates to the field of insect control equipment technology, specifically a slit-hole granule dosing machine with a drug mixing function. Background Technology

[0002] A crevice and hole granular pesticide dispenser is a specialized device designed to deliver granular pesticides into hard-to-reach spaces such as crevices and holes. It kills pests by delivering insecticidal granules into wall cracks, floor gaps, and other similar locations.

[0003] Currently, existing granular pesticide dispensers lack the ability to crush granular pesticides during application. Large particles tend to accumulate at the slit entrance, hindering subsequent pesticide delivery and preventing the pesticide from penetrating deep into the core area of ​​the pest's nest, thus reducing the control effect. Therefore, we need to propose a granular pesticide dispenser with a pesticide mixing function. Utility Model Content

[0004] The purpose of this invention is to provide a granular pesticide dispenser with a pesticide dispensing function that can quickly penetrate the narrow gaps in insect nests and reach the core area, overcoming the shortcomings of traditional mechanical dispensing which is difficult to penetrate deeply, increasing the probability of contact between the pesticide and the insects, and improving the killing effect on the insects, thereby solving the problems mentioned in the background art.

[0015] This invention utilizes a pulverizing mechanism and an air supply and delivery mechanism. The pulverizing mechanism breaks down the formulated insecticide, desiccant, and attractant, mixing them together. As the pulverized pesticide is delivered through a delivery pipe, the air supply and delivery mechanism mixes it with a high-speed airflow, forming a gas-solid two-phase flow. This allows the pesticide to quickly penetrate the narrow gaps in insect nests and reach the core area, overcoming the limitations of traditional mechanical delivery methods. Furthermore, the finer particles of the pulverized pesticide, when mixed with gas, have better diffusion properties, evenly covering the inside of the nest and increasing the probability of contact between the insecticide and the pests. Simultaneously, the synergistic effect of the desiccant and attractant is enhanced, prolonging the duration of the pesticide's efficacy. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A slit-hole granule dispensing machine with drug proportioning function includes a housing 1, a support plate 2 fixedly installed inside the housing 1, a mixing tank 3 fixedly installed inside the support plate 2, a pulverizing mechanism for pulverizing granule drugs is provided inside the mixing tank 3, a conveying pipe 13 is connected to the bottom of the mixing tank 3, a second valve 14 is fixedly installed on the conveying pipe 13, and one end of the conveying pipe 13 extends to the outside of the housing 1.

[0023] The interior of the housing 1 is equipped with a gas supply and delivery mechanism for transporting the pulverized drug. The gas supply and delivery mechanism connects the mixing tank 3 and the delivery pipe 13.

[0024] In an optional embodiment: the crushing mechanism includes a crushing motor 10, a crushing frame 11 and a support 12. The crushing motor 10 is fixedly installed on the top of the mixing tank 3. The crushing frame 11 is fixedly connected to the output shaft of the crushing motor 10 through a coupling. The support 12 is fixedly connected inside the mixing tank 3. The crushing frame 11 is movably installed inside the support 12.

[0025] It should be noted that the pulverizing motor 10 and the pulverizing frame 11 work together to crush and evenly mix the insecticide, desiccant and attractant in the mixing tank 3, ensuring that the particle size is small so that the crushed drug can enter the gaps or holes.

[0026] In an optional embodiment: the top of the housing 1 is fixedly connected from left to right to a first storage tank 4, a second storage tank 5 and a third storage tank 6. The bottom of the first storage tank 4, the second storage tank 5 and the third storage tank 6 are all connected to a connecting pipe 8. The lower end of the connecting pipe 8 is connected to the top of the mixing tank 3. A first valve 9 is fixedly installed on the connecting pipe 8. A sealing cover 7 is fixedly installed on the top of the first storage tank 4, the second storage tank 5 and the third storage tank 6.

[0027] It should be noted that the first storage tank 4 contains insecticide, the second storage tank 5 contains desiccant, and the third storage tank 6 contains attractant. The first storage tank 4, the second storage tank 5, and the third storage tank 6 are all made of transparent material, which makes it easy to observe the amount of medicine when mixing, so as to facilitate the mixing of insecticide, desiccant, and attractant.

[0028] In an optional embodiment: the gas supply and delivery mechanism includes a pressure pump 17, a first gas delivery pipe 18, a third valve 19, a second gas delivery pipe 20, a first check valve 21 and a fourth valve 22. The pressure pump 17 is fixedly installed at the bottom of the housing 1. The second gas delivery pipe 20 is connected to the gas outlet of the pressure pump 17. One end of the second gas delivery pipe 20 is connected to the delivery pipe 13. The fourth valve 22 and the first check valve 21 are both fixedly installed on the second gas delivery pipe 20.

[0029] It should be noted that the pressure pump 17, the first gas delivery pipe 18 and the second gas delivery pipe 20 work together to facilitate the discharge and delivery of the pulverized medicine in the mixing tank 3. A second check valve is installed on the first gas delivery pipe 18. The first check valve 21 and the second check valve can prevent the medicine from entering the pressure pump 17 through the first gas delivery pipe 18 and the second gas delivery pipe 20, thus affecting the normal operation of the pressure pump 17.

[0030] In an optional embodiment: one end of the first gas supply pipe 18 is connected to the second gas supply pipe 20, the other end of the first gas supply pipe 18 is connected to the mixing tank 3, and the third valve 19 is fixedly installed on the first gas supply pipe 18.

[0031] In an optional embodiment: one end of the delivery pipe 13 is connected to a hose 26, one end of the hose 26 is fixedly mounted with a handle 15, and one end of the handle 15 is fixedly mounted with a spray pipe 16.

[0032] It should be noted that the flexible hose 26 allows the hand handle 15 to flexibly adjust the spray direction to adapt to the application needs of narrow gaps or complex angles.

[0033] Hose 26 withstands the positive pressure (typically 0.2~0.5MPa) of the pneumatic conveying system, preventing the hose from expanding or rupturing due to air pressure. Hose 26 is made of polyurethane (PU), which has the advantages of high wear resistance, resistance to bending fatigue, and suitability for dynamic applications.

[0034] In an optional embodiment: a pressure relief pipe 24 is connected to the mixing tank 3, a pressure relief valve 25 is fixedly installed on the pressure relief pipe 24, and a sealing door 23 is fixedly installed on the side of the box 1 to seal the box 1.

[0035] It should be noted that the pressure relief pipe 24 and the pressure relief valve 25 are used in conjunction to avoid the risk of overpressure in the mixing tank 3.

[0036] The usage process of this utility model is as follows: By opening the first valve 9, the insecticide, desiccant, and attractant in the first storage tank 4, the second storage tank 5, and the third storage tank 6 fall into the mixing tank 3. The amount of insecticide, desiccant, or attractant fed in through the first storage tank 4, the second storage tank 5, and the third storage tank 6 is observed. After the ratio of insecticide, desiccant, or attractant is adjusted, the crushing motor 10 is started. The output shaft of the crushing motor 10 rotates, driving the crushing frame 11 to rotate. When the crushing frame 11 rotates, it crushes the insecticide, desiccant, and attractant, breaking them down and mixing them evenly to ensure that the particle size is small.

[0037] After the insecticide, desiccant, and attractant are crushed, the third valve 19 and the fourth valve 22 are opened, the spray pipe 16 is aligned with the gap or hole, and the pressure pump 17 is started. Air is drawn out by the pressure pump 17 and transported through the second air supply pipe 20 and the first air supply pipe 18 to the mixing tank 3 and the conveying pipe 13. The air in the mixing tank 3 forms a positive pressure, which forces the dust out of the conveying pipe 13. The dust is then transported through the conveying pipe 13 and the hose 26. The air delivered to the conveying pipe 13 mixes with the crushed pesticide, creating a gas-solid two-phase flow. The pesticide can be sprayed through the delivery pipe 13, hose 26 and spray pipe 16 to quickly penetrate the narrow gaps in the insect nest and reach the core area. This overcomes the shortcomings of traditional mechanical delivery, which is difficult to penetrate deeply. In addition, the broken pesticide particles are smaller and have better diffusion after mixing with gas. They can evenly cover the inside of the nest, increasing the probability of contact between the pesticide and the pests. At the same time, the synergistic effect of the desiccant and the attractant is enhanced, prolonging the duration of the pesticide effect. When killing pests, workers can wear gas masks or chemical protective clothing, gloves and goggles to ensure the safety of the workers. This is in line with the modern trend of environmental protection and humanization in pest control.

[0038] The control method of the crushing motor and pressure pump in this application is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail in this application. The device is powered by a built-in power supply or an external power supply.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
