  According to German Offenlegungsschrift No. 2 951 910, it is known to operate a fan with a forage harvester, according to which a relatively narrow chopper drum arranged partially at the front and at the end of the driver's station is provided with a pipe. upwardly directed obliquely upward and which passes on one side of the driver's seat and to the top of his roof A la

some disadvantages.

  This is how the ascending pipe directed upwards, passing obliquely beside the driver's station, prevents him from having the free view to a side. When the limit of land to be harvested lies on this side, this obstruction of view leads to crop losses The relatively long upward upward rising up to the roof of the

  relatively wide chopper drums.

  On the other hand, the rotary fan disposed above the slewing ring ensures the transport

  of the product of the harvest already reduced beforehand with

  ascending dune above the swivel ring, and its drive device produce vibrations, so that the ascending pipe, to absorb these vibrations, must be made all the more stable and fixed several times to the device base Also the pivoting device must be made in a fairly solid construction and with a significant use of material, it must during the pivoting of the duct ejection curve, cause in its movement, the entire assembly of the rotary fan and of the corresponding driving device. It is also known from DE OS 3,024,663 a forage harvester provided with a take-off line following the hashing device Has an ejection tower from the hash device and directed upwards, and becoming tighter in the direction of ejection, an ejection paddle wheel is added near its upper end. The axis of rotation of the latter is located transversely to the axis of the tower and extends parallel to

  the axis of rotation of the chopper drum.

  This invention eliminates some of the disadvantages

  However, the disadvantage that the withdrawal channel is shrinking forward of the fan provided for ejection remains there again In the DE-OS mentioned above it can be seen, in the case of a drum chopper relatively narrow, already a noticeable narrowing on the ejection tower surfaces

On the other hand, because of the fact that the paddle wheel is mounted on one side of the tower, there is a considerable wall friction.

  is taken into the curved ejection duct by eliminating the energy dissipating wall friction and

  without introducing any additional training source.

  The object of the invention is to provide such a device - a device for evacuating the cut product for a chopper picker which makes it possible without difficulty to collect and accelerate the ejection of the crop product by using only the most low drive power and this as well for

  relatively wide chopper drums.

  The device according to the invention is for this purpose characterized in that an additional accelerator preferably formed of two rotors, mounted horizontally

  in the direction of the walk, with its two rotors,

  symmetrically with respect to the width of an exhaust duct coming into their lower zone, by their lateral surfaces and their frontal surfaces directed towards the rear face of the driver's station, to penetrate approximately vertically into a rectangular opening of the discharge channel directed obliquely upwards, the rotors being able to be actuated in opposite directions by means of an inversion mechanism

  of sense receiving its movement from the control motor.

  In the case of a forage harvester with a relatively narrow chopper drum, the additional accelerator at the end of the discharge channel is equipped with only one rotor mounted in the direction of travel. the exhaust duct following the chopper drum is designed to be narrowed on all sides upwards. The rotors operate in opposite directions by means of a gearbox connected to the chopper drum.

Harvest collected from the receiving drum is concentrated on a transverse auger conveyor and fed through the chopper feed and precompression rollers From the chopper drum the chopped crop product is transported by an evacuation channel directed obliquely upwards, over the width of the chopper drum, passing below and behind the driver's station. The two rotors rotating in opposite directions which penetrate vertically into the rectangular upper opening of the duct.

  The arrangement of the two rotors facing each other and rotating in opposite directions makes it possible to avoid the losses

  The additional accelerator 8 is constituted, as represented in FIG. 2, by two rotors 9, 9 'operating in opposite directions, whereas in the case of a forage harvester comprising a relatively narrow chopper drum 6, as shown in Figure 3,

  only one rotor 9 has been provided in the accelerator 8.

With this arrangement, provided at right angles to the chopper drum 6, the support housing of the rotors 9, 9 ', the harvested crop product which arrives in the width of the discharge channel 7 is finds, from the rotors 9, 9 'operating in opposite directions and arranged on both sides above the evacuation channel 7, concentrated and driven on the diameter of the

  For this purpose, the rotors 9, 9 'penetrate, in their lower zone, by their lateral surfaces 14, 14' and their end faces 11, 11 ', to near

  Thanks to this possibility that we have to receive the
