The boom sprayer attachment consists of two aluminum hollow sections (50 x 25 mm) of 4 m length with 16 numbers of nozzles. The nozzles are spaced at 450 mm apart. A reciprocating pump (40 m x 25 mm) is mounted on the power tiller with the help of a stand . The drive is transmitted from the clutch pulley of the power tiller through ‘v’ belt. A 25 mm dia heavy-duty alkathene suction hose carries the spray chemical from the tank kept in the power tiller trailor to the pump inlet. The delivery line from the outlet of the pump is divided into two lines by means of a two way cock to each of the two aluminium sections. The spray boom with nozzles are carried by two persons with a “belly rest” and “neck belt” provisions for easy handling and spraying of chemicals on the crop foliage. A regulator valve with a by-pass line to the tank is also provided in the delivery line to control the excess pressure and discharge rate. |
