Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable pesticide sprayer capable of automatically stirring,

The present invention relates to a portable agricultural chemical sprayer, and more particularly, to a portable agricultural chemical spraying machine in which a pump is built in and the pesticide can be sprayed automatically by a user's operation, The present invention relates to a portable agrochemical sprayer capable of automatically agitating agitated pesticides by the built-in pump.

There are various kinds of pesticide sprayers used for spraying biochemical pesticides to control pests or weeds that occur during the cultivation of crops, depending on the application amount of pesticide and the cultivation area to be handled by the pesticide sprayer, It is a portable pesticide sprayer which is constructed so that the grower can carry it directly by hand or tie it to his back.

The portable agricultural chemical sprayer is divided into a manual pesticide sprayer and an automatic pesticide sprayer. The manual pesticide sprayer is a device for spraying the pesticide while spraying directly by the user. The automatic pesticide sprayer is provided with a suspenders A chemical liquid tank and a motor and a pump are installed in the lower part of the chemical liquid tank, thereby spraying the chemical liquid in the chemical liquid tank by the action of the pump.

In the above automatic pesticide sprayer, the user installs a suspender on the chemical liquid tank as described above, and uses the chemical liquid tank on the user's shoulder. If the chemical liquid tank is used by administering only one kind of chemical liquid, However, when two or more chemical fluids are administered to one chemical fluid tank and stirred and used, the user needs to agitate two or more chemical fluids contained in the chemical liquid tank from time to time. This is because, when two different kinds of chemical liquids are put into one chemical liquid tank, the density and the viscosity of each other are different, so that when they stay in the chemical liquid tank for a long time, they are separated naturally and the concentration between the upper and lower ends of the chemical liquid tank is different Therefore, it is intended to spray the pesticide having the concentration and the composition ratio intended by the user.

However, since the above general automatic pesticide sprayer does not have any component for stirring the chemical solution in the chemical solution tank, the user often places the chemical solution tank on the back of the chemical solution tank in order to stir the chemical solution in the chemical solution tank, It is necessary to stir the chemical solution in the tank manually. This causes a great inconvenience to the user and wastes unnecessary time and energy, and even if the chemical liquid in the tank is structured with a pump and a motor, it is not stirred properly.

Therefore, in using the general automatic pesticide sprayer described above, the user generally stirs the chemical solution only by the means such as a stick only for the first time when the chemical solution is administered into the chemical solution tank, and then shakes the chemical solution tank on the back . However, even when the chemical liquid tank is shaken and agitated while the chemical liquid tank is in the above-described state, the chemical liquid in the chemical liquid tank is not stirred to a significant extent. This is especially useless when the pesticide to be poured into the chemical liquid tank is used only by stirring the liquid medicine in the liquid state and the powdered medicine in the powder state rather than using only the chemical liquid in the liquid state, The drug is not agitated at all with the chemical solution, and most of the drug is submerged on the bottom of the chemical liquid tank. In order to solve this problem, it is necessary to effectively stir the internal chemical solution and the powder medicine in real time.
