Description

Powder Spreader {Powder Spreader}

The present invention relates to a powder spraying device, and more particularly, to a movable electrostatic powder spraying device that ejects powder having a negative charge and is provided movably.

Ticks are arthropods and belong to the arachnids. The body is pocket-shaped, and the distinction between the head, the back, and the abdomen is not clear, and the tentacles are short. Ticks inhabit almost all environments, play the role of decomposers, eat harmful arthropods, and spread disease and cause stress by parasitic on crops and livestock worldwide. Thus, the economic damage caused by ticks is great. In particular, the chicken mite (Dermanyssus gallinae) is a pest that feeds on and feeds on rodents, including chickens and wild birds. Chicken mites are ectoparasites distributed worldwide, and are subtropical ectoparasites with a size of 1 mm, and infected chickens show symptoms such as itching and sleep disturbances.

Chicken ticks correspond to the order of the spider river tick, and due to their ecological nature, they require blood from livestock for nesting. Accordingly, chicken ticks have a habit of transferring blood to livestock. It is known that it is usually parasitic in cattle sheds and equipment, and moves mainly at night for blood-sucking, wounding the skin of livestock, and feeding blood. This habit is highly related to the transmission of disease agents in livestock. In addition, it shifts to the worker and causes the worker a sense of itching. Houses with a very high density of chicken ticks can cause disgust in people.

Accordingly, farmers or workers purchase and use commercially available products such as Wagufree and Elector made of carbamate-based, organophosphorus, and organic chlorine-based pesticides to solve this problem, but the effect due to resistance is weak or pesticides on eggs. Because of this residual, chicken mites (mites, wagumo) cannot be effectively controlled.

When infected with chicken mites, laying hens and breeders may die due to blood-sucking stress, resulting in lower egg production rates and infection with bacteria and diseases. In particular, the damage caused by poultry typhus, one of the diseases transmitted by chicken ticks, is a disease designated as a type 2 livestock infectious disease according to the Livestock Infectious Disease Prevention Act, and when infected, diarrhea symptoms appear and mortality is high. Therefore, chicken mites are the number one alert for farmers in the summer, and they cause not only direct damage, but also secondary damage as a medium.

In general, chickens growing in the wild repeat the movement of digging the ground and rubbing the body or sprinkling sand with their feet. This is a survival instinct to get rid of ticks and insects that are parasitic on the body. However, chickens trapped in tight spaces such as iron cages have no way of removing ticks or insects on their own.

Therefore, spawning chickens deteriorate the quality of eggs due to stress from chicken mites. Breeding farmers use pesticides to remove ticks and insects that live in chickens. Since domestic chicken breeding farmers are not registered as effective products as animal drugs or quasi-drugs to control ticks parasitic in chickens, some livestock farms use agricultural chemicals for crops without permission. However, it is highly toxic and causes extreme irritation and stress to animals, leading to problems such as weight loss and lowering of spawning rates. In addition, it is known that the pesticide component absorbed in the chicken body is very likely to be discharged through eggs.

Tick control products registered as pesticides have several limitations for use in animals. Generally, among the substances used in the pesticide field, there are substances that cannot be applied as veterinary drugs or quasi-drugs for animals, which fall under Class 2 of the substance classification set by the EPA (U.S. Environmental Protection Agency) and cannot be applied to veterinary drugs. Therefore, when pesticides are used in livestock farms, it is recommended to eject low-concentration drugs or control agents as much as possible inside and around empty houses without livestock. However, chicken breeding farmers use a lot of methods of sprinkling directly on the body of chickens because it is difficult to eradicate chicken ticks because the fertility of chicken ticks is so good. If pesticides are applied directly to the body of a chicken, the pesticide component can be absorbed into the body through the chicken's skin and remain. In order to solve this problem, chicken tick insecticide must be used according to the method of use, and must comply with the holiday period, and for the spawning chickens to prevent the pesticide from remaining in the chicken body and eggs, it is safe not to get drugs or control agents on eggs, etc. Should be used In particular, spraying pesticides directly onto chickens must be avoided. To this end, the technology of ejecting drugs or control agents into the bingy house is important as well as selecting the correct control agent.

If the control agent such as chemicals or silica is not sprayed properly, the control effect is deteriorated, so an ejector suitable for the type of livestock is required. Drugs can be sprayed with a general high-pressure spray, but the maximum control effect should be achieved by spraying a sufficient area with a small amount of drugs according to an appropriate pressure. In order to spray silica or diatomaceous earth products, a device capable of spraying silica is required. Currently, the silica ejector used in domestic cages is generally ejected using a fertilizer spreader, so that silica is not ejected evenly, and there is a problem that the silica is not sufficiently applied to the surface of the chicken cage. In addition, since it is sprayed through wind and pressure, there is a problem that the amount applied to the surface of the cage is less than that of the injection amount, which is inefficient and takes a long treatment time.

An object of the present invention is to provide a powder spraying device for efficiently spraying and adhering powder to livestock houses such as a cage having a complex structure by using static electricity.

In addition, an object of the present invention is to provide a powder spraying device that reduces the amount of powder used and treatment time, and allows the powder to be electrodeposited and adhered to the barn, thereby increasing the persistence of the control effect by the powder.

6 is a view showing a state where powder is ejected from the nozzle gun of FIG. Referring to FIG. 6, the nozzle gun 300 may be connected to a power transmission line 301 and a hose 302. In addition, an electrode (not shown) may be provided in the nozzle gun 300. The power transmission line 301 is connected to the electrostatic generator 500 so that a high voltage may be applied into the nozzle gun 300. The high voltage applied to the nozzle gun 300 may ionize the air delivered through the hose 302. Accordingly, the particles of the powder P may be negatively ionized through air. The anionized powder (P) may adhere to the house 20 by proceeding along the grounded house 20 and the electrostatic field formed. Thus, the powder (P) can be effectively sprayed on the barn (20). In addition, the amount of powder (P) used and treatment time can be reduced, and the effect of controlling chicken mites, which varies depending on the level of each farm, can be uniformly increased. In addition, the powder (P) sprayed on the barn 20 may be electrodeposited and/or adhered to the barn 20. Accordingly, it is possible to increase the control effect and persistence of the powder (P).

In the above-described example, generating static electricity inside the nozzle gun 300 has been described as an example, but the present invention is not limited thereto. For example, the electrostatic generator 500 may be provided in the hose 302 to negatively ionize the powder P in the process of moving the powder P from the hose 302 to the nozzle gun 300.

In the above, the present invention has been described through the embodiments, but the above embodiments are merely for explaining the spirit of the present invention and are not limited thereto. One of ordinary skill in the art will understand that various modifications may be made to the above-described embodiments.
