Abstract

Abstract:

Design of orchard multi-duct sprayer air delivery system for the problems of uneven airflow distribution and poor droplet penetration of traditional ring-shaped air delivery sprayers. The optimal structural parameters were determined by simulation of the internal flow field consisting of the air duct， transition interface， flexible duct and air outlet， and the optimal parameters of the fan speed and total height of the air outlet were determined by external flow field simulation. According to the simulation results， the optimal combination of parameters was 170 mm duct width， 40° conversion interface angle， 123 mm flexible duct diameter， 52 mm outlet width， 2 160 r/min fan speed， and 1.9 m total height of the outlet. The air delivery system of the sprayer was set up according to the optimized parameters and designed for the airflow velocity test， and the results showed that the simulated values were in good agreement with the test values， and the error of airflow velocity on the left and right sides of the outlet was less than 10%. The droplet penetration was good， the deviation of droplet deposition density between canopies was less than 12%， and the droplets were evenly distributed in the vertical direction of the canopy.
