A HYDRAULIC TAPPING SYSTEM CHARACTERIZED BY A 2000-MM LINEAR TELESCOPIC ARM ADJUSTABLE IN ROTATION AT MORE OR LESS 45 ° OF THE ROAD

摘要

Semiautomatic hydraulic ditching machine characterized by a single element incorporating a linear retractable telescopic arm providing constant travel up to 2000 mm without changing the programmed milling degree and angle, the arm is composed of at least three structural elements (a) slidably resting on a flange (b) intended to be fixed to the vehicle (tractor ...) and a milling element (g) with a guard (f) which carries out the bleeding and a shoe arm positioning (d), allowing regular milling without butt or bowl provoking water flow disruptions. An adjustment system of the arm (a) on the flange (e) provides a rotation adjustment of plus or minus 45 ° perpendicular to the road for the purpose of making spiked grooves to improve the flow of water in the ditch when the roads have gradients. The telescopic arm (a) being hydraulically liftable from the driver's cab of the vehicle between two grooves, limits the size of the machine on the road network between two bleeding operations. Finally the guard (f) of the milling machine simultaneously evacuates rubble.
