Sleeve Boom Sprayer-I: Design and Development of Tractor Mounted Sleeve Boom Sprayer for Cotton

摘要

Air assisted spraying with a sleeve boom sprayer for field crops is a new concept in India. Efforts have been made to design and develop a sleeve boom sprayer which could be operated by a 30-35 hp tractor. The axial flow blower was developed with a capacity of 3.1 m~3/s. Three types of blades; cambered, tapered and flat undersurface were designed and fabricated with FRP and aluminium. A common aluminum hub was developed to accommodate ten blades at a time with provision to adjust the blade stagger angle. The boom, sleeve and hydraulic system for the sprayer were also developed. A tapered sleeve was designed and made with fiber reinforced PVC material in order to get uniform air velocity at each outlet.
