BOOM SPRAYER AND BOOM SPRAY MACHINE HAVING THE SAME

摘要

The cleaning work machine includes a central frame portion, first and second spraying frame portions, and an obstacle detecting skin. The central frame portion is disposed at the center of the passenger control device and extends in the horizontal direction from the center. The first and second spray frame portions include at least two spray wings each of which is connected to both sides of the central frame portion and is horizontally foldable and has a plurality of spray units for spraying the solution. Wherein the obstacle detection skin is disposed on at least one of the spreading wings of the first spray frame part and the spreading wings of the second scatter frame part and includes a sensor for detecting an obstacle located in front of the travel direction of the travel part, Folds the lower spraying wings, which are located farther from the center than the sensing spraying wings with sensors that detect obstacles, horizontally. Accordingly, it is possible to easily and reliably avoid the obstacles arranged in the front, and the obstacle avoiding method can be configured more simply and easily and efficiently.;
