Figure 1 shows the rotor elevator 1 which moves on vertical slides by means of two jacks, which comprises a helical screw with a right and left hand thread provided with cleaning flaps and sections, it allows removal of material from a silo from top to bottom up to 3.50 metres. The conveyor 2 is made up of a return screw and a conveying device. The return screw is constituted by two endless half-screws, left and right handed, and by plates interposed between the threads. The assembly conveys the material in the case progressively as it is removed from the silo. The conveying device, provided with bars made of an angle section fixed to two chains, rotates from bottom to top around the deck. The case 3 having a capacity of 5 m<3>, with a moving bottom with bars, ensures a uniform dispensing, by means of two spreaders with sectional helical screws. An inspection window allows the filling and dispensing to be monitored. The hydraulic assembly is made up of a hydraulic reservoir 4 of 100 litres capacity, a generator 5 driven by a transmission connected to the traction-force connection, a distributor 6 with variable positions allowing the removal of material from a silo and the dispensing of it without leaving the seat of the tractor, various motors: rotor elevator motor 7, conveyor and return screw motor 8, motor of the moving bottom and of the spreaders 9, jacks 10 for the rotor elevator whose lowering is adjustable and jacks 11 for adjusting the conveying and dispensing height (1.20 metres). <IMAGE>
