Description

[0001] PESTICIDES SPRAY ASSEMBLY [0002]

The present invention relates to a pesticidal sprayer assembly for spraying air with pesticides, and more particularly, to a pesticidal sprayer assembly for spraying air with pesticides, and more particularly to a pesticidal sprayer assembly comprising a housing having a bottle containing pesticides, And a pneumatic spraying unit for spraying air together with the pesticide through a motor member provided in the housing to form an air spraying unit. By separately configuring the driving pump and the motor member, the spraying force of the air is increased, To an agrochemical sprayer assembly capable of spraying and spraying over a long distance.

In order to improve the yield of crops, the pesticide is developed and sprayed on the crops. The pesticide is diluted with water in the pesticide pail, and the user operates the artificial pump with the pesticide on the back, while the other hand uses the pump It was sprayed on the crop to be sprayed with the pesticide by holding the sprayer composed of the nozzle configured to spray the pesticide supplied through the supply pipe.

In this case, a pump for pumping is constructed by driving a motor, and the suction port side is immersed in a large water tank containing pesticide diluted in water, a long supply pipe is formed at the outlet side, and a spray nozzle is formed at the end of the supply pipe. The pesticide was sprayed to the crops by spray nozzle using the sprayer and sprayed with pesticide.

Conventional pesticide application spraying type power sprayer which was supplied to the farmhouse was designed for spraying water crop or crop pesticide, and its schematic structure is composed of a blower connected to the engine and a chemical solution bottle, Since the chemical solution in the chemical solution bottle is supplied through the rubber hose to the air injection nozzle by natural water, the chemical solution is mixed with the air spray and sprayed in the horizontal direction such as the water pressure and the field crop, In case of deep discussion, if the field is deep and the shoulder is low, the hydraulic head of the power sprayer is low and the water pressure is low. In this case, if the rice grows large, the spray pipe should be maintained to be slightly inclined upward, but if the spray pipe is inclined As a result, the water head (water pressure) becomes weak, In addition, when disinfecting in the grove of orchard or the like, it is necessary to keep the spray tube high, so that the position of the chemical liquid pipe at the end of the spray pipe becomes higher than the position of the chemical liquid bottle and the air is sprayed because there is no water pressure, There was a problem that could not be done.
