KNAPSACK POWER SPRAYER
Features:
It consists of a frame on which a high density polyethylene tank, fuel
tank, engine, delivery pipe, shock proof cushion, and a spray hose.
The pump adopts horizontal gear driving. It is powerful and stable in
pressure. As it is oil-soaking type, the lubricating effect of crank
box is positive. It adopts double cylinder pump, which raises
operational efficiency. The piston is heat treated and wear resistant.
'V' packing adopts special materials so it is durable. The engine has
electronic ignition, which is easy to be operated and maintained. Its
engine has high power to weight ratio. It uses gasoline as a fuel and
produces one power stroke for each 1800 of crank rotation. Pressure is
controlled by oil valve; spraying pressure is changeable freely and up
to 30 kgf/cm2. Its structure is rigid; materials are
excellent and easy to maintain. It can also be used for dusting and
ULV application. |

TRACTOR DRAWN BOOM SPRAYER
Features:
The sprayers essentially consists of a tank which is made of fibre
glass or plastic, pump assembly, suction pipe with strainer, pressure
gauges pressure regulators, air chamber, delivery pipe, spray boom
fitted with nozzles. These are hydraulic energy sprayers. They utilize
PTO power of the tractor to operate the pump of the sprayer. Basically
the spray boom can be arranged in two ways; ground spray boom and
overhead spray boom. The overhead spray boom is designed for tall
field crops and the planting is done in such a way that it leaves an
unplanted strip of about 2.5 m width for operation of the tractor.
Therefore a planted strip may be 18-20 m wide and after every planted
strip a fallow strip has to be left for tractor operation. For ground
spray boom the planting has to be done in rows keeping in view track
width of the tractor. It is suitable for use when the crop height is
small.

AERO-BLAST SPRAYER
Features:
The machine consists of tank of 400 litres capacity, pump, fan,
control valve, filling unit, spout adjustable handle, pressure
regulator and spraying nozzles to release the pesticide solution in to
stream of air blast produced by the centrifugal blower. The air blast
distributes chemical in the form of very fine particles throughout its
swath, which is on one side of tractor. The major portion of swath is
taken care of by the main blast through the main spout and the
auxiliary nozzles cover the swath area near the tractor. The sprayer
is mounted on the tractor 3-point linkage and is operated by tractor
PTO. The orientation of air outlet can be adjusted for its direction
and width of coverage.
