There is disclosed apparatus (10) for shredding long stem material, such as cylindrical bales of straw or silage, and which comprises a fixed base (11), a drum (12) rotatable on the base in the direction (X) in order to guide the material towards the base and to cause it to move in a rotary movement over the base when the drum is inclined to the vertical in a working position, a rotary shredder device (13) mounted on the base (11) in a housing (15) and having a set of chopper blades (20) mounted along the length of a drive shaft (14), a slot (16) in the base (11) extending aproximately radially with respect to the centre (26) of the base and having opposed sides (16a and 16b) which define the slot (16), and a discharge outlet (17, 18) communicating with the interior of the housing and operative to discharge shredded material from the housing (15). The shaft (14) extends parallel to and along the length of the slot (16), and the upper active part of the paths of rotation of the chopper blades (20) comprises movement in a direction generally perpendicular to and between the two opposed sides (16a and 16b) of the slot (16), to provide an improved shredding effect on the material. In addition, the axis (21) of the slot (16) is forwardly inclined at an angle of preferably 30 to 60 DEG to the vertical axis V-V, with respect to the direction of rotation (X) of the drum, in order to still further improve the shredding action applied to the material which is caused to tumble over the base as it is fed towards the action of the chopping blades. |
