Strautmann Verti Mix Double K - Mixing Container and Mixing Auger

Structure and Functions
5.1 Mixing container and mixing auger
Fig. 15
The fodder mixing trailer is hitched to the tractor by means of the
drawbar (1). The p.t.o. shaft of the tractor mechanically drives the
mixing augers (2) via the PTO drive shaft (3), the switchgear (4)
(optional equipment), the PTO drive shaft (5), the angular gearbox (6),
the PTO drive shaft (7) and the angular gearbox (8).
The propeller shafts (3) and (7) are equipped with a shear bolt
coupling each (9). In case of overload, the respective shear bolt of the
shear bolt coupling shears off thus interrupting the power flux
between tractor and mixing auger(s). This protects the power train of
the mixing augers from being damaged.
The driving speed (n) of the mixing auger depends on the p.t.o. shaft
speed of the tractor. At a p.t.o. shaft speed of 540 rpm, the driving
speed of the mixing auger is, depending on the machine model and
the type of angular gears:
• n = 20, 24 or 29 min
-1
for Verti-Mix Double K 1300 and 1500,
• n = 24 or 29 min
-1
for Verti-Mix Double K 1800 and 2100.
During the mixing process, the mixing augers first transport the fodder
components filled in upwards in the centre of the mixing augers. The
fodder then falls down the container wall so that a mixing cycle is
generated.
The diameter and the height of the mixing auger depend on the size
of the mixing container.
