Spraying: Lechler solutions for 'on-demand' treatments
The Lechler Group, one of the world's leading manufacturers of spray nozzles and precision systems for agriculture – with 900 employees (400 of whom are at the German headquarters in Metzingen) and 12 branches worldwide – arrives at Agritechnica with a significant series of innovations. It starts with the all-in-one nozzle assembly system that combines three components in a coordinated manner: the ergonomic EasyFitCap bayonet cap, the nozzle filter with integrated molded gasket and a multi-functional assembly tool. The system is simple and effective: the newly developed nozzle filter replaces separate gaskets and remains securely fixed in the cap thanks to the integrated molded gasket. This way the filter cannot fall or get stuck in the nozzle holder. The assembly wrench works as a multi-tool for the bayonet nut, is compatible with various types of bayonet caps and also allows for precise alignment and angle of the nozzle. On the single nozzle front, Lechler launches the ARE 30, a solution primarily intended for phytosanitary applications in row crops. Designed for narrow spray bands from 5 to 30 cm, the nozzle operates at a spray angle of 30°. The rectangular spray pattern ensures uniform coverage within the target area. Thanks to its broad droplet spectrum – from medium to very large – the ARE 30 is able to limit the drift effect. Lechler points out that the ARE 30 can be used for both open field and row treatments.
The new LS 20 is on the same wavelength. With a narrow 20° spray angle, the nozzle allows for precise application of plant protection products to the smallest target areas, reducing chemical use and drift. The parabolic spray pattern ensures even coverage when multiple nozzles overlap, allowing even the smallest spots to be treated efficiently. Fully compatible with PWM (Pulse Width Modulation) systems, the LS 20 allows for flexible and precise control of the distributed quantities. Thanks to its low flow rates and small size, it is ideal for use with autonomous robots and localized spraying systems.
Also in this segment the German company presents the XD (Xtreme Drift reduction), non-venturi flat nozzle with built-in pre-atomize and dosing orifice. This design enables uniform droplet generation with a low fine droplet fraction (regardless of whether the nozzle is operated in conventional or PWM-controlled operation). The wide pressure range – from 1.5 to 8 bar – allows the XD to be used at various driving speeds and in a wide variety of weather conditions, achieving droplet sizes ranging from ultra-coarse to extremely coarse, with high quality coverage and penetration into the crops. The "nozzle in the cap" design allows for quick, tool-free changes in the Multijet bayonet system.The new Xamount system, capable of safely moving liquid plant protection products from the can to the spray tank, rounds out the circle of innovations.
Xamount allows for complete emptying of containers with automatic and integrated cap cleaning or the precise partial extraction of set quantities, for which you can specify the desired density and volume. The system is equipped with a weighing mechanism that allows for precise dosing regardless of the viscosity or temperature of the plant protection product, and complies with ISO 21191. Once the can has been completely emptied, the system activates automatically: a vertical mobile probe thoroughly cleans the bottom, sides and neck without any contact between the user and the plant protection product. Thanks to the 12V power supply, Xamount can be operated via a vehicle connection. Intuitive operation via a water- and dust- protected membrane display with keypad ensures safe handling even when wearing gloves.
