Forage harvester with an arrangement for measuring the harvested material throughput

A forage harvester having a combustion engine drivingly connected to a chopper cylinder via a first drive belt, and to a first end of a drive shaft of a discharge accelerator, the discharge accelerator being arranged, with respect to a direction of harvested material flow, downstream of the chopper cylinder, a second end of the drive shaft of the discharge accelerator is drivingly connected to a kernel processor via a second drive belt, the kernel processor being arranged between the chopper cylinder and the discharge accelerator and the discharge accelerator comprises support discs which extend radially, and which are drivingly connected to the drive shaft, and paddles for the conveyance of harvested material, which are attached to the support discs, wherein:

• the support disks are attached to a hollow shaft enclosing the drive shaft;
• a sensor is arranged between the drive shaft and the discharge accelerator for the determination of the force transmitted by the drive shaft to the discharge
• the discharge accelerator is connected to a flange which comprises first projections, which protrude radially inward, the drive shaft is connected to a rotor which comprises second projections which protrude radially outward, and the sensor is arranged between the first projections and the second projections;
• and
• the rotor is arranged within a hollow inner space of the flange.
