Manifold linkage for a field sprayer and method of measuring distance between the manifold linkage and a crop or ground

摘要

A distributor boom for a field sprayer and a method for measuring the distance between the boom and a crop stand and / or soil are described. Accordingly, a measuring device is present on the distributor linkage, which comprises an ultrasonic sensor mounted on the distributor linkage for measuring the distance between the distributor linkage and a plant stand. Furthermore, the measuring device has at least one reflector mounted on the distributor linkage for deflecting a sound cone emitted by the ultrasonic sensor to the plant stand / ground. As a result, a blind area of the ultrasonic sensor can be laid in a region of the distributor linkage above its lower edge. This improves the distance measurement, in particular in the area immediately below the distributor linkage.
