The invention relates to a blower chopper with a feeder, intake rollers and a connected chopping drum, from which the cut material is fed to the intake of a conveyor fan via a conveyor chamber extending parallel to the chopping drum and connected to the drum over its length. ■ ^: V ■ / ■■■■ "

In such a known type drum chopper with a permanently connected Conveyor fan has so far generally been followed that the chopped material was fed to the pressure side of a conveyor fan via slides or the like. Or so that the chopped material is thrown into a collecting funnel, from which it is the blower suction sliding or parallel to the chopper shaft by means of a screw or. Like. Was supplied. When using such-funnel stowage can occur, especially with silage, because the moist chopped material sticks to the hopper walls and can give rise to bridging;

The aforementioned blower chopper is used to solve this problem designed so that the Iföckseltronimel parallel to their Axis is followed by a cylinder (8) open at both ends, whose Perimeter tangential on one side in the direction of throw of the chopper merges into the scope of the cutterhead and that at one end can be connected to the intake of a conveying fan whose UeI- ' Ie or its drive shaft to a.

But it is also possible to have the fan motor shaft outside of the cylinder via a coupling with a drive shaft of the
