OPTICAL SPOT SPRAY TECHNOLOGY REGISTRATIONS FOR HERBICIDES
SUPERIOR MODE OF DETECTION
WEEDit’s near infrared technology only detects the chlorophyll present in living plants sending a quick response to the nozzles which release the spray onto the weed. This superior mode of detection allows for faster travel speeds and the ability to target even smaller weeds. WEEDit improves at night because there is no interference from sunlight and weeds are often less stressed meaning the reaction to active chlorophyll is greater. The WEEDit system utilises two speed sensors to increase or decrease the reaction time of the nozzles during cornering, resulting in a more accurate and efficient job across the paddock.
Changes in background conditions such as soil type and stubble are not a problem for WEEDit's auto-calibration system. The WEEDit is not affected by changes in background conditions because it is only measuring active chlorophyll. For the operator this means even better targeting of small grasses.
SENSOR AND NOZZLE PLACEMENT
WEEDit sensors are placed every 1 metre across the boom and control 5 nozzles (individually) on 20 cm spacings. Benefits from this design are less weight due to less sensors being required, and a smaller spray footprint when a weed is sprayed. This set-up provides great savings on chemical. The nozzle spacing of 20 cm also allows for better penetration in stubble with less shading of small grasses.
ENHANCED ELECTRICAL SYSTEM
Weed detection systems place large demands on electrical supplies. The WEEDit overcomes this issue by running at 48 volts. This not only gives superior solenoid operation but current draw is 4 times less than other weed detection equipment using 12 volt systems. Faster solenoid operation also means quicker spraying speeds in the paddock.
The WEEDit system provides high speed operation and up to 25 km/h while cornering. High speed operation gives you greater productivity and better utilisation of your investment.
WEEDit System – easy to use intelligent display provides constant monitoring of solenoid and sensor operation, with malfunctions or errors reported on screen. This display allows for setup and sensitivity adjustments from the easy to use menu. The controller also monitors increased boom speeds on corners and automatically adjusts response time to ensure the nozzle hits the target.
IN CAB MONITOR
The easy to use display has simple warnings for low pressure, sensor faults and voltage. The intelligent design allows for easy fault identifications and greatly increases productivity as the requirement to visually check and monitor the machine is dramatically reduced. This monitor also keeps a record of nozzle activation, chemical use and sensor history.
The Croplands Accumulator controls the flow from the pump to the nozzles. It utilises a 200mm diaphragm, supported by a regulated air supply. Through combining the high flow centrifugal pump, the fast acting diaphragm controls the nozzle fluid pressure and volume rapidly from single nozzle activation to full boom. This system maintains a boom line pressure of 3 bar for fast response at all times. When the sensor detects a weed, within milliseconds the solenoid is firing at full pressure. Nozzle speed is essential for efficient weed coverage.
CENTRAL CONTROL PANEL
From a central point, the operator can take charge of all the filling, mixing and flushing. When the operator camlocks a 2" filling hose to the non-return valve on the sprayer, they can select to fill the spot spray tank, flush tank or main tank. The electronic flow metre measures part tank filling. The secondary rotary valve allows selection of the chemical suction probe, 60 litre Chem-e-flush hopper or return to spray position. The control panel also allows selection of spot spray tank rinse, main tank rinse, agitator and chemical suction probe rinse through a series of valves.
