While direct injection spraying, where ‘neat' chemical is applied as needed from its own storage tank on the sprayer and not pre-mixed as a bulk solution, is not new, this is Amazone's approach.
The DirectInject system consists of an additional 50 litre tank with its own metering system, which is integrated into the storage compartment of the Amazone UX 01 Super trailed sprayer.
The tank is easily accessible from the ground and can be filled safely.
In the field, the sprayer driver can activate the metering of DirectInject from the cab at the touch of a button.
The supplementary product from the DirectInject tank is then added to the spray agent from the spray agent tank in a twin-line system.
Pre-mixed spray agent from the spray agent tank and the plant protection agent from the DirectInject tank are held in a second spray line in the boom. When the direct feed system is activated, the mixture is applied through the nozzle bodies and nozzles via several injection points in the boom.
Amazone's DUS pro high-pressure recirculation system enables the spray agent in the spray line to circulate with the pre-set spray pressure at all times, even when the nozzles are closed.
Circulation is stopped when the direct feed system is activated, meaning that the spray agent from the spray agent tank is not mixed with the product from the DirectInject tank.
Since DirectInject can work with undiluted chemicals, unused quantities can be returned to the original container of the product after application.
As a result, the amount of plant protection agent actually needed does not have to be known before application, nor do mixed residual amounts have to be dealt with afterwards.
The entire system can be cleaned automatically and remotely from the tractor cab after application. All components are integrated in a Comfort-Pack on the sprayer.
The DirectInject direct feed system can be used with UX 01 single-axle sprayers with standard ISOBUS communication and AmaSwitch or AmaSelect single nozzle control with a DUS pro high-pressure recirculation system.
