Abstract
The invention relates to an automatic sprayer which belongs to agricultural tools. The automatic sprayer comprises a pesticide tank, a liquid supplementation/pressurization device arranged inside the pesticide tank, a floating device arranged in the lower part of a pressure chamber, a three-way pipe arranged below the floating device in a way that one end thereof is connected with the liquid supplementation/pressurization device and the other end thereof is connected with a switch. The pressure chamber and the pesticide tank are fixedly arranged side by side on a pedestal. A pressure-driven cover is arranged on the pressure chamber. The pressure-driven cover is assembled with the pesticide tank as a whole via bolts. A return hole is formed at the site close to the pressure chamber in the upper part of the pesticide tank. A pressure meter and a safety valve are arranged on the top of the pressure chamber. One end of the safety valve is inserted into the pressure chamber and the other end thereof is connected with the return hole on the pesticide tank. The automatic sprayer has reasonable structure and convenient use; can spray pesticides continuously after once compression with uniform spray and high spray efficiency; and is safe to use with the combined use of pressure meter and the safety valve. Additionally, the pressure chamber is mounted outside the pesticide tank, so as to avoid the pesticide corrosion to the pressure chamber and prolong the service life.
