DETAILED DESCRIPTION OF THE INVENTION

[0028] As shown by the attached drawings, the invention incorporates a traction bar (1), to which two swivel gearboxes (2) are installed, one of which on the front part of the traction bar, after the cardan shaft (3) for coupling to the tractor power outlet (not shown), and the other one on the rear part of the traction bar, allowing the tractor to work displaced over both sides of the arrangement, not overloading the cardan shafts (4) installed between said swivel gearboxes (2), also including, between said swivel gearboxes, an intermediate gearbox (2a), through which it is possible to control the transmitted rotation, by means of the central gearbox (5), located after the rear swivel gearbox, to the gearboxes (6) activating the beater drums (7), for their better efficiency. This rotation control may be optionally performed by the central gearbox (5), making the gearbox (2a) become unnecessary. Another gear (8) is also envisaged, located on the shaft of one of the beater drums which, by means of a chain (9), activates the gear (10) of the gearbox (11), which activates the pulley (12) which, by means of a belt (13), activates the pulley (14) activating the distributor roller (15), on which opposed edge a pulley (16) is designed which, by means of a belt (17), activates the pulley (18) of the front crosswise shaft (19) of the screen arrangement (20), in which central part an eccentric shaft (21) is included, which synchronously promotes the alternate linear movement of said screens, neutralizing the vibrations caused by their displacement. On the rear edges of the beater drums, pulleys (22) are also included, which, by means of belts (23), activate the pulleys (24) of the fans (25), on which front pulleys (26) are designed, which, by means of belts (27), activate the front pulleys (28) of the double pulley arrangements, while the rear pulleys (29) activate, by means of belts (30), the pulleys (31) of the gearboxes (32) transmitting rotation to the pulleys (33) which, by means of belts (34), activate the pulleys (35) rotating horizontally located choppers (36).
