Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a chemical sprayer.

[0002]

[Prior art]

 A sprayer is used for spraying a chemical such as a liquid pesticide. The main part of this sprayer is composed of a chemical tank for storing the chemical, a pump for pressurizing the chemical, a spraying part for atomizing and spraying the chemical in a mist, and a liquid sending hose connecting the chemical tank and the spraying part. ing. Sprayers are classified into manual sprayers and power sprayers according to the power source of the pump. The manual sprayer is a portable type of a shoulder type or a backpack type, and is used in a small area for spraying a chemical solution, for example, in a home garden. As the pump, a hand-operated reciprocating pump mounted on the sprayer body is used. Pumps include a chemical pump type that directly applies pressure to a liquid and an air pump type that pressurizes air and applies the pressure to the chemical. In both cases, the pressure lever is manually moved up and down to generate pressure. Due to the pressure, the chemical is sent to the spraying section and sprayed. Power atomizers are used in a wide range of spraying chemicals, for example, in paddy fields. A device that generates high-pressure air, such as a compressor, is used to pressurize the chemical. High-pressure air is generated by a compressor or the like, and the high-pressure air is supplied to the chemical tank, so that the chemical is pressurized. Therefore, the chemical solution is sent to the spraying unit and sprayed.

[Problems to be solved by the invention]

 However, the manual sprayer has a problem that the structure of the sprayer is complicated, heavy, and large because the sprayer is equipped with a pump. In addition, since the pump is driven manually, the operation is difficult. In addition, in the case of a power atomizer, a means such as a compressor for generating air higher in pressure than the atmosphere is required in addition to the atomizer itself. Therefore, it takes time to prepare a compressor. Furthermore, it is necessary to prepare a compressor etc. at the place to spray, which is troublesome.

[0004] In view of such circumstances, an object of the present invention is to provide a chemical sprayer which has a simple structure, is small in size and light in weight, can easily prepare for spraying a chemical solution, and can easily perform a chemical solution spraying operation.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic sectional view of the chemical sprayer of the present embodiment. As shown in the figure, the chemical sprayer comprises a pressurized tank 10, a transport pipe 20, a chemical tank 30, a spraying section 40, and a pressurizing section 50.

First, the pressurized tank 10 will be described. Reference numeral 11 indicates a main body. The main body 11 has a pressure resistance higher than the terminal water pressure of the water supply. In addition, as the material of the main body 11, aluminum, FRP, rubber, polyamide fiber (for example, nylon manufactured by du Pont) and the like can be adopted. When the material of the main body 11 is aluminum, FRP, or the like, the shape may be maintained by its own rigidity. When the material of the main body 11 is rubber, polyamide fiber, or the like, it is preferable to support the main body 11 with an appropriate frame.

The main body 11 is supported by a pair of pedestals 12 on the left and right. It is preferable to adopt wheels instead of the pedestal 12. In this case, the centers of the left and right wheels may be connected by a bar, and the bar may be rotatably attached to the main body 11. This is preferable because it can be easily moved.

At the bottom of the main body 11, a supply port 13p for supplying tap water is formed. An air vent hole 14p is formed in the upper part of the main body 11. When tap water is supplied into the main body 11 from the supply port 13p, air in the main body 11 is evacuated from the air vent hole 14p. An air vent hole cover 15 is attached to the air vent hole 14p. The air vent hole cover 15 is for preventing water from leaking from the air vent hole 14p during spraying. A transport pipe 20 is attached to the upper part of the main body 11 in a liquid-tight manner.

Next, the transport pipe 20 will be described. The transport pipe 20 is a T-shaped pipe, and is provided with three ports of a chemical solution outlet 21p, a chemical solution tank mounting port 22p, and a chemical solution inlet 23p. The transport pipe 20 is attached to the upper part of the main body 11 of the pressurized tank 10, the chemical liquid tank mounting port 22p is arranged inside the main body 11, and the chemical liquid jet port 21p and the chemical liquid inlet 23p are outside the main body 11. Is placed. Note that the transport pipe 20 may be a simple steel pipe or the like.

Next, the chemical liquid tank 30 will be described. A chemical tank 30 is attached to the chemical tank attachment port 22p of the transport pipe 20. The chemical tank 30 is for storing chemicals such as various agricultural chemicals. As a material of the chemical liquid tank 30, rubber, polyamide fiber (for example, nylon, trade name of du Pont) or the like can be used. When the chemical solution tank 30 is made of rubber, the rubber is very elastic and can be contracted and expanded. Therefore, a desired amount of the chemical solution is stored inside the chemical solution tank 30 regardless of the size of the chemical solution tank 30. Can be. When the chemical liquid tank 30 is made of polyamide fiber, various chemical liquids can be stored in the chemical liquid tank 30 because the polyamide fiber has excellent chemical resistance.

The chemical is poured from the chemical inlet 23p, passes through the transport pipe 20, and enters the chemical tank 30 through the chemical tank mounting opening 22p. A lid 24 is attached to the chemical liquid inlet 23p to prevent the chemical liquid from being discharged from the chemical liquid inlet 23p when the chemical liquid tank 30 is pressurized to fill the air vent hole 14p with the chemical liquid. .

Next, the spraying unit 40 will be described. One end of a pipe 41 such as a steel pipe, a copper pipe, a rubber hose, a hose made of a polyamide fiber (for example, nylon made by du Pont) or the like is attached to the chemical jet port 21p of the transport pipe 20. I have.

A spray amount control valve 42 that can be opened and closed is attached to an intermediate portion of the pipe 41. The spray amount control valve 42 can adjust the spray amount of the chemical solution by its opening degree. Note that the spray amount control valve 42 may be provided between the chemical solution outlet 21p and one end of the pipe 41, and a stop valve or the like may be adopted.

The other end of the tube 41 is provided with a nozzle 43 for spraying a chemical solution in a mist state.

Next, the pressing unit 50 will be described. One end of a supply pipe 51 such as a water hose is attached to the supply port 13p of the pressurized tank 10. The other end of the supply pipe 51 is attached to a water tap fc. The supply pipe 51 may be a steel pipe, a copper pipe, a rubber hose, a polyamide fiber (for example, nylon manufactured by du Pont) nylon hose, or the like.

The supply pipe 51 is provided with a drain valve 52. The drain valve 52 is used to drain water filled in the main body 11 of the pressurized tank 10 after the spraying operation is completed or when a chemical solution is added. Note that the drain valve 52 may be provided at the bottom of the main body 11.

As described above, in the chemical sprayer of the present embodiment, the main body 11 of the pressurized tank 10 is not equipped with a pump, so that the structure can be made simple, small, and lightweight.

The operation and effect of the chemical sprayer of the present embodiment will be described. First, the lid 24 is removed, and the chemical to be sprayed is poured from the chemical inlet 23p of the transport pipe 20, and is put into the chemical tank 30. After the desired amount has been charged, the lid 24 is attached to the chemical solution inlet 23p.

Next, one end of the supply pipe 51 of the pressurizing section 50 is attached to the supply port 13p of the pressurized tank 10, and the other end is attached to the tap fc of the water supply. After removing the air vent cover 15 and confirming that the drain valve 52 and the spray amount control valve 42 are closed, the faucet fc is opened. Then, tap water of the faucet fc is supplied to the inside of the main body 11 of the pressurized tank 10 from the supply port 13 p through the supply pipe 51.

When the inside of the main body 11 of the pressurized tank 10 is filled with water and tap water overflows from the air vent hole 14p, first, the faucet fc is closed, and the lid 15 for the air vent hole is attached to the air vent hole 14p. Next, when the faucet fc is opened, the water pressure of the tap is applied to the water inside the main body 11, and the chemical pressure is pressurized from the outside by the water pressure. This is because the water pressure of the tap water propagates through the water inside the supply pipe 51 and is transmitted to the water inside the main body 11.

Therefore, according to the chemical sprayer of the present embodiment, since the chemical tank 30 is pressurized by the water pressure of the tap water, there is no need to prepare a compressor or the like that generates high-pressure air. Becomes easier. Further, since the chemical solution tank 30 can be pressurized by the water supplied from the tap water, there is no need to pressurize the chemical solution manually, and the operation is easy.

When the spray amount control valve 42 is opened with the nozzle 43 of the spray unit 40 facing the tree or the like on which the chemical solution is to be sprayed, the chemical solution is sprayed in an amount corresponding to the degree of opening of the spray amount control valve 42. From the start to the end of spraying, almost constant tap water pressure is applied to the chemical liquid tank 30, so that the spraying amount decreases and the spraying amount varies due to the pressure drop in the tank, as in the case of a manual pump. Absent. For this reason, the fluctuation of the spray amount is small, and a constant amount of spray can be performed.

When the spraying is completed, the faucet fc is closed, then the lid 15 for the air vent hole is removed, and when the drain valve 52 is opened, the water inside the main body 11 of the pressurized tank 10 is discharged. Thereafter, by removing the supply pipe 51 from the faucet fc and the supply port 13p, the cleaning is completed.

As described above, according to the chemical sprayer of the present embodiment, since no pump is provided, the structure can be simplified, and the size and weight can be reduced. Also, the work becomes easier because no human power is used to pressurize the chemical. Furthermore, since the chemical tank is pressurized by the water pressure of the tap water, there is no need to prepare a compressor or the like that generates high-pressure air, and the preparation of the chemical spray is simplified.
