Solar Powered Duster And Sprayer
ABSTRACT
As the name suggests this project is about an agricultural duster that is powered by solar energy. The agricultural duster is used for dusting of solid powder form pesticides and insecticides like DDT and insecticides in liquid forms as well.
In this project an aluminum frame is constructed using aluminum bars to keep the weight of the frame low. In this frame a retractable link is fixed to the top end of which a solar photovoltaic panel is fixed that converts solar power into electricity. This electricity is then provided to battery via a charging circuit and is used for charging the battery. Electric power from this battery is given to an electric motor via control switches, by controlling which entire device can be operated. To the shaft of this electric motor a blower fan is connected. This blower blows high speed air into the blower pipe. This blower pipe is held with hand by the device operator and is directed onto the area where he wishes to spray the pesticides / insecticides. The insecticide reservoir is connected to the blower pipe. By continuously feeding this insecticide to the blower pipe the same is spread or sprinkled where wished. Liquid insecticide is sprayed on the crops using Spray pipe, which receives liquid from a reservoir with the help of a pump. This pump is driven by a another DC motor that receives power from the same battery. Thus insecticide in liquid form is sprayed where wished.
The project can also run emergency lamp using battery power thus this project can be of very much use and can be very beneficial for farmers.
