The grain mass, received from the concave and straw walkers, is exposed to a
two-step leaning system. The top and seed sieves are suspended on the levers with opposite stroke and different amplitudes, with the view of mutual balancing of inertia forces and obtaining of more regular grain level. The separate sieve adjustments allow to conform rapidly and precisely to different harvest conditions.
Powerful air blowing
A six-bladed fan produces a dense air stream, blowing all the sections of the cleaning system. The speed of the fan rotation is continuously adjustable from the cab and displayed on the control panel. The extended down range of speed allows to reduce the losses at harvesting of small-seeded crops, and also is convenient for light bypass removal.
Less time for unloading
Patented «wave» sieve: different sizes of the top sieve rakes ensure the even air flow distribution.
Practice shows that the grain unloading takes about 5% of the shift. For reduction of this time ACROS is equipped with a grain tank of imposing capacity (9000 l) and a
high-duty unloading elevator (90 l/s).
Self-contained rethreshing unit helps to avoid the drum overload, so at steady efficiency, the damage of grain is minimized.
Height, length and turning angle of an unloading auger are meant for unhampered unloading in any freight transport, even in a long trailer, and the harvester is equipped with a header 9,0 m wide.
Humid grain unloading
It’s possible to sample the grain directly from the cab floor.
Special attention is given to the steady operation of an unloading device in conditions of high humidity. The unique patented apparatus Smart Launch reliably protects
a high-speed mechanism against overload, and the
hydro-pulsators exclude «hanging» of grain in the tank.
