Abstract

The machine allows the placing of small troughs in trenches, made up by a loading platform (1) with a rotating conveyor (4) or sliding (7) for the small troughs (CA) to a feeding train (2) directing them towards an aligning box (3). The feeding train has folding sections (21), (22) and (23), being the central section (22) the one that has the coupling and linking means (24) to the tractor (T) and also where the loading platform (1) is journalled, the first section (21) is the one receiving the small troughs from the rotating conveyor (4), the second section (22) receives them from the sliding conveyor (7) and the third section (23) deposits the small troughs (CA) in the aligning box (2), which aligns the small troughs (CA) on which the corresponding covers (P) are overlapped by a device based on a framework (8) and an inclined platform (9).

angle in relation to the upper frame (46) and the rest of the set of the rotating conveyor 4;

further characterized in that it comprises;

a conveyor (7) for the supply of small troughs (CA) rows up to the feeding train (2);
