AGRICULTURAL MACHINE, PARTICULARLY OF THE ROTARY MOWER TYPE, COMPRISING AN IMPROVED CHOPPING DEVICE

摘要

The invention relates to an agricultural machine which is fitted with a chopping device (4), said chopping device (4) comprising: a guard (9); at least three chopping members (7a, 7b, 7c, 7d, 7e) which are disposed above said guard (9) and which are linked thereto so as to pivot around a shaft (8a, 8b, 8c, 8d, 8e) which is directed upwards; transmission elements which rotate said chopping members (7a, 7b, 7c, 7d, 7e) around the respective shafts (8a, 8b, 8c, 8d, 8e); and, among the chopping members (7a, 7b, 7c, 7d, 7e), at least two adjacent chopping members (7b, 7c, 7d, 7e) which rotate in opposite directions (10b, 10c; 10d, 10e) converging towards the front. The inventive agricultural machine is characterised in that the distance (12) separating the rotary shafts (8b, 8c; 8d, 8e) of two adjacent chopping members (7b 7c; 7d, 7e) rotating in opposite directions (10b, 10c; 10d, 10e) converging towards the front is greater than at least a distance (13, 22) separating the rotary shafts (8a, 8b; 8c, 8d) of two adjacent chopping members (7a, 7b; 7c, 7d) having directions of rotation (10a, 10b; 10c, 10d) which do not converge towards the front. The arrangement of said chopping members (7a, 7b, 7c, 7d, 7e) in this manner can be used advantageously to improve the removal of the chopped product towards the rear of said chopping device (4).
