Influence of walking speed and working width on discharge rate and amount of solution required
Practical experience has shown that walking speed can vary by 5 to 6 meters/ min. A slower walking speed
means that it is necessary to reduce the discharge rate or the amount of solution and vice versa. Walking 6
m/min slower than the specified 60 m/min (1m/s) represents a reduction of 10%.
In our example the setting of the metering unit would have to be reduced by 10%, from 2.7 to 2.43 I/min.
If this is not done, the quantity of slolution required would increase 10%, from 54 liters to 59.4 liters.
The variation in working width can be considerable, especially if the field has not been marked with stakes.
A reduction of working width at a given walking speed means that the discharge rate would have to be
reduced or the amount of solution increased and vice versa. An 0.5 m reduction, after having calculated for
a working width of 3 m, represents a reduction of 17%.
In order to extend the mistblower’s vertical reach (tall trees), the spray tube must be held steady or moved
only very slowly to ensure that the spray mist is properly formed and stable.
Use of standard accessories / special accessories
Detachable nozzle and baffle screens (standard accessories)
Pressure pump (special accessory)
In our example the setting of the merering unit would have to be reduced by 17%, from 2.7 to 2.24 I/min, If
this is not done, the quantity of solution required would increase 17%, from 54 liters to 63.2 liters. If both
these variations occurred at the same time, the setting of the metering unit would have to be reduced by
27%, from 2.7 to 1.97 I/min, because the quantiry of solution required would otherqise incerase 27%, from
54 liters to 68.6 liters.
The pressure pump is recommended for applications in which the spray tube has to be held at an upward
angle of more than 30 It helps maintain a constant discharge rate in all apray tube positions. Furthermore,
active ingredients which tend to settle in the container are held in suspension by constant agitation of the
solution.
lt may be necessary to change the normal cone-shaped patern and direction of the spray jet for certain
crops and applications. A detachable nozzle and various baffle screens are used for this purpose.
The deflector baffle screen diverts
the spray jet at an angle. lt can be
used for under-leaf treatment of
low-growing crops.
The tapered baffle screen causes
the solution to be discharged, finely
atomized in a short, broad and
dense cloud.
The dual deflector baffle screen
splits the spray jet into two and
thus allows two rows of plants to
betreated simultaneously.
