SCREWING SYSTEM FOR A HARVESTING MACHINE FOR AGRICULTURAL APPLICATIONS WITH A SINGLE AND AGAINST DEFLECTOR

摘要

A scattering system (40) of an agricultural vehicle (20) for scattering harvest residues over a field comprises: a first scattering device (42) containing a first series of blades (120) configured to rotate about a first axis (46) to define a first scatter path (124); a second spreader (44) including a second set of blades (122) configured to rotate about a second axis (48) to define a second spreading path (128), the second spreader (44) and the first spreader ( 42) are placed side by side; a deflector (140, 180) including a first deflector portion (142) for deflecting the first scatter path (124), and a second deflector portion (146) for deflecting the second scatter path (128); and a deflector drive (160, 182) connected to the deflector (140, 180). The scattering system (40) is characterized in that the deflector drive (160, 182) is configured to move the first deflector portion (142) and the second deflector portion (146) of the deflector (140, 180) in an oscillating pattern in a direction (D , 184) which is roughly parallel to the first axis (46) and / or the second axis (48).
