Intelligent low-loss pesticide powder spraying plant protection machine for dense crops

Abstract

The application discloses a low-loss intelligent pesticide powder spraying plant protection machine for dense crops, which comprises a mobile base, a base plate arranged above the mobile base, a transmission system, an electric control assembly, a fan, a blockage prevention discharging assembly, a spiral feeder, a Venturi mixing pipe, a horizontal rod rotary driving assembly, a pesticide spraying horizontal rod and a spraying pipe arranged in sequence from the head to the tail of the base plate. The low-loss intelligent pesticide powder spraying plant protection machine for dense crops is provided with a gas spraying cavity in the pesticide spraying horizontal rod, an annular gas curtain is formed around the spraying pipe, the lateral diffusion of the pesticide powder is restrained, the drift loss is reduced, the spraying angle is adjusted by driving the whole pesticide spraying horizontal rod to rotate through the horizontal rod rotary driving assembly, the deposition uniformity of the pesticide powder at each height of the dense crop canopy is improved by cooperating with the internal flow dispersion structure of the spraying pipe, the bridge forming condition of the pesticide powder is destroyed by arranging a spiral flow guide groove in the inner wall of the tapered bottom of the pesticide storage box and cooperating with a vibrating motor, the discharging blockage is prevented, and the feeding stability is ensured.
