Презентация на тему на английском языке на тему EDX eSeed precision air seeder (бакалавриат 3-й курс)

the EDX eSeed precision air seeder is supplied
via the

high voltage system (“High Voltage”) of the tractor. Via TIM (Tractor Implement
Management) the control electronics on the tractor are accessed. The implement controls
itself through its own intelligence and makes use of the two most current and modern technologies
in the range of ISOBUS for further improvement and efficiency of the machine.

Short abstract:

EDX eSeed – detailed view 230 V metering servo-motor

EDX eSeed

systems for the blower fan and metering on the

EDX eSeed have been replaced by high voltage motors (400 V) and are accessed via the power inverters on the tractor. The metering drive systems have been replaced by efficient servo-motors with clearly improved dynamics.
On large pneumatic seed drills, the blower fans are hydraulically driven, an arrangement which offers a high degree of flexibility but, due to poor efficiency results in high fuel consumption. More and more comfort functions mean
that the electric 12 V systems on usual tractors meet their limits.
Hydraulics of the new system are only needed for the actuation of hydraulic rams, for example when folding. An additional advantage of the system is the independence from the engine speed of the tractor so that it is possible to operate the tractor at its optimum fuel consumption.

efficiency of the total system is clearly
improved. On hydrostatic

drive systems a mechanical efficiency of 60 % is anticipated.
With an electrical system today, more than
85 % is achieved. 20 kW, consumed as mechanical power, requires approximately 33.3 kW drive capacity in a hydraulic system, whereas in an electric drive line only approximately 23.5 kW are necessary. Here alone, fuel savings of up to 50 l of diesel per day are possible.

%) are realised
because the seeder sends its demands for
each

individual operating parameter to the
tractor. The implement controls the tractor
and connects with it to become a modular selfpropelled
vehicle – thus implementing Tractor-
Implement-Management (TIM). So, for example,
on the headland, the speed of the blower
fan drive can be reduced automatically by the
implement resulting, apart from additional
fuel saving in a clear reduction of noise level.
