Electro mechanical Truck Sampler for correct
sampling directly from truck with remote control.
The Rakoraf Core Sampler is the fastest and easiest method to take an
accurate sample from an open trailer. The sample is taken while the trailer
is still on the weighbridge. The telescopic arm with the core tube can be
extended or retracted, be turned horizontally 0 to 350 degrees, and can also
be raised or lowered vertically.
When the core tube is forced downward into the load, the grain, due to the
down pressure, is pushed upwards into the inner chamber of the core tube and
carried to the receiving chamber located in the weighbridge office via steel
and plastic tubing. In the receiving chamber the air is separated from the
sample and the clean air is circulated back through the air motor and
discharged through the outside chamber of the core tube.

The air circulation system with the patented
CONVAC system secures a correct sample eliminating the "vacuum cleaner
effect". Each time the probe is inserted into the load a sample is taken.
From a 1 metre load a 600 gram sample is taken, if the load is 2 metre the
sample is 1200 gram. Sample size is independent of the time the probe is
inserted in the load. Only the material (grain) that is forced into the tube
is taken as the sample. The sample is taken right to the bottom of the
material layer, a factor especially significant when sampling peas, where
smaller impurities settle at the bottom. When the core sampler is stopped,
the samples is automatically emptied out from the receiving chamber. Should
the driver by mistake drive away before the sampler is taken out of the
load, the sampler is equipped with a break away hinge will give with the
motion so no damage is done to the sampler or trailer. |

The compact handheld joystick which has all moving functions in one handle
can activate up to 3 moving functions at the same time. The joystick speeds
up the operation and it is possible to take 5 samples in 40 seconds. The
joystick is connected to the sampler with a single multiplug and if required
you can replace your old type push button unit very simply. Push button for
working lamp and horn.
