KNAPSACK SPRAYER
|
|
Features:
Knapsack sprayer consists of a pump and an
air chamber permanently installed in a 9 to 22.5 liters tank. The
handle of the pump extending over the shoulder or under the arm of
operator makes it possible to pump with one hand and spray with
the other. Uniform pressure can be maintained by keeping the pump
in continuous operation.

7.2 POWER KNAPSACK SPRAYER
|
|
Features:
It consists of two plastic tanks (fuel
and water/dust), engine, pump, spray hose, rope starter,
delivery pipe, cut-off-cock, shoulder straps and a frame. It
has a small 2-stroke petrol/kerosene engine of 35 cc to which
a centrifugal fan is connected. The fan produces a high
velocity air stream, which is diverted through a 90-degree
elbow to a flexible (plastic) discharge hose, which has a
divergent outlet. Upon rotation of the engine the fan produces
a high velocity air stream. The control valve for the spray is
opened gradually and adjusted for the desired flow rate. The
operator directs the discharge hose to the target. It can be
converted for dusting and ULV application.

TRACTOR MOUNTED BOOM SPRAYER |
|
Features:
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 is small. The sprayer essentially
consists of a tank which is made of fiber glass or plastic, pump
assembly’s suction pipe with strainer, pressure gauges pressure
regulators, air chamber, delivery pipe, spray boom fitted with
nozzles. The complete sprayer is mounted on 3-point linkages of
the tractor. It uses high pressure and high discharge pump as the
number of nozzles may be up to 20 depending upon the crop and make
of the sprayer. |

SELF-PROPELLED HIGH CLEARANCE SPRAYER
|
|
Features:
The machine has a chassis with 1200-mnl
ground clearance, four wheels, and 20 hp diesel engine, gearbox,
water tank, seat for the operator, spray pump and boom with 18
nozzles. The nozzles are spaced at 675 mm and total boom width is
10.80 m. The boom height can be adjusted form 31.5 cm to 168.5 cm
to suit different crops and can be folded during transport. The
front two wheels are narrow in width (20 cm) and are given drive,
while the rear wheels are steering wheels. Fenders have been
provided in front of the drive wheels to deflect the crop branches
away from the wheels for reducing mechanical damage. The wheel
track is 135 cm and during operation2 rows of cotton crop come
under the machine chassis’s machine has four forward speeds and
one reverse speed. The 1 st and 2nd gears are for field operation
while 3rd and 4th gears are for road transport. The field speed is
up to 5 km/h and the road speed is up to 25 km/h. |
