Description

[Detailed Description of the Invention] This invention is a two-fluid spraying method that uses compressed air to spray a chemical solution, and is used to exterminate flying pests in livestock, poultry houses, and agricultural greenhouses, disinfect airborne bacteria, and deodorize. This invention relates to an automatic drug spraying device for the purpose of.

In general, the chicken bug, which is a blood-sucking insect of chickens, was controlled by adding antibiotics to the feed, but recently it has been prohibited to add antibiotics to the feed, so it is necessary to prevent chicken mosquitoes in livestock, chicken houses, and agricultural greenhouses. It is desired to improve the surrounding environment.

In other words, in order to eliminate the cause of the occurrence of chicken weevil, the environment was maintained by spraying chemicals on grass patches, but this was not sufficient.

In addition, conventional spraying of chemicals inside agricultural greenhouses involved a person carrying a sprayer entering the sealed greenhouse, so no matter how much the sprayer wore a dust mask, etc., it was impossible to spray chemicals. There was also an occupational health problem in that the chemicals could be inhaled into the human body, causing health problems.

This invention was made in view of the above-mentioned circumstances, and is an automatic chemical spraying device that is capable of killing flying pests in indoor spaces such as livestock, poultry houses, and greenhouses, is harmless to the human body, and is preferable in terms of occupational hygiene. The purpose is to provide

Therefore, in order to achieve the above object, the present invention
A pressure-resistant piping tube is installed in a room such as a poultry house or an agricultural greenhouse, and nozzles are attached to the piping tube via T-shaped branch pipes at predetermined intervals, and a chemical solution tank is detachably attached to each nozzle, and the above-mentioned A compressor that sends compressed air to the piping tube is connected to the piping tube via a control panel, and the control panel is placed outside the livestock/poultry house or agricultural house, etc., and the chemical solution in the chemical solution tank is pumped indoors using compressed air. It is characterized by controlling the atomized spray into the space from outside.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an automatic spraying device installed in a livestock/poultry house or an agricultural house, and FIG. 2 is a plan view showing its piping assembly. In the figure, 1 is a compressor, 2 is a control panel, 3 is a piping tube, and 4 is a nozzle, to which a chemical tank 5 is detachably attached. The compressor 1 has a performance corresponding to the number of nozzles 4 installed in the poultry house, and is operated by a power switch on the control panel 2.

Further, the piping tube 3 is cut with a pressure-resistant plastic tube or the like at each arrangement interval of the nozzles 4,
As shown in FIG. 3, a nozzle 4 is set through a T-shaped branch pipe 6 consisting of a socket, a plug, etc.

The above piping tube 3 is a beam or horizontal member that is easy to illustrate.
Tightened with cable ties to pipes, etc. On the other hand, the nozzle 4 and chemical tank 5 are shown in FIGS.
It is constructed as shown in the figure, and the chemical liquid tank 5 is attached and removed by a cap 7, making it convenient for chemical exchange and nozzle cleaning.

Further, as shown in FIG. 5, when the compressed air a from the compressor 1 is introduced into the nozzle 4, the pressure regulator 8
moves backward against the spring 9, the needle valve 10 opens, and the chemical liquid passage becomes negative pressure, so that the chemical liquid b in the chemical liquid tank 5
is atomized and atomized by compressed air a. Since the operation of the compressor 1 at this time is controlled by the control panel 2 placed outside the room, the disinfection work can be carried out without the need for workers to remain indoors. During this disinfection work, it is desirable to seal the room to be worked on.

Since the present invention is constructed as described above, it has the following various features.

(1) Multiple spray nozzles are connected by piping tubes, so they can be easily matched to the structure of the building and placed in the right place, and the control panel that controls the spray is placed outside to maintain a disinfecting environment. Since the spraying condition can be controlled from a place isolated from the environment, the health of the workers will not be harmed and this is preferable in terms of occupational hygiene.

(2) In addition, in systems where chemical liquids are transferred from a common chemical tank through pipes, sediment accumulates inside the pipes and causes clogging, but in the present invention, each nozzle is equipped with a dedicated chemical tank. There is no clogging phenomenon as described above.

(3) Furthermore, in the present invention, a dedicated chemical tank is attached to each nozzle, so the type of chemical liquid filled in the chemical liquid tank can be changed for each tank, for example, the type of chemical liquid can be changed, or The amount of liquid to be filled can be changed, making it possible to design a chemical spray that best suits the environment being disinfected. In particular, since a dedicated chemical liquid tank is provided for each nozzle, the chemical liquid can be divided into small amounts for each nozzle, so that the chemical liquid can be sprayed evenly without uneven distribution.

Furthermore, it is important to vary the type of chemical solution because it allows water-soluble chemicals to be used differently depending on the purpose, such as insecticidal, sterilizing, deodorizing, etc.

(4) Furthermore, since the chemical tank provided for each nozzle can be made into a small container, it is possible to spray a small amount of chemical liquid, and the chemical liquid to be sprayed has no effect on plants and animals living in the environment to be disinfected. can be easily tested.

(5) The nozzle is set with the chemical tank, making it easy to install and remove, and maintenance is easy, as changing the chemical and cleaning the nozzle are convenient.

(6) The direction of the nozzle installed in the piping tube at predetermined intervals can be adjusted arbitrarily, and effective spraying can be performed using the minimum necessary amount of chemical within the area to be sprayed.
