Application of hot liquids through porous materials for weed control and crop improvement, combines fluid supply system with exhaust-fed weed after-heater

摘要

A supply tank (2), liquid heater (1) and applicator containing porous material (3) are used with a duct (4) for hot exhaust gases. The leading region of the applicator has built-in porous components, comprising tubes, hoses or similar profiles. In the trailing section, the after-heating zone includes baffles, where the energy of the exhaust gases is employed. This prevents premature cooling of the wetted weeds. An Independent claim is implicit, for the corresponding machine.
