The invention relates to a mower of a combine or other harvesting machine for Grain-mountable device with insertion mouth for converting the machine to harvest maize and similar crops. Known devices of this type consist mainly of torpedo-like ones Divider tips and counter-rotating feed chains housed in these dividers. Such Devices have the disadvantage that long set-up times are required in order to be in the normal state Combines intended only for the grain harvest for the harvest of long-stemmed crops to remodel. Another disadvantage is that such a device has many separate ones Gear elements required, which complicate the structure of the device and to an undesirable extent more expensive. Furthermore, the high weight of the known devices is also disadvantageous. It has shown, that as a result, for example, deformations and even destruction on the platform of the combine harvester very soon appear.

Other versions suitable for maize harvest have several picking devices, each consisting of two adjustable, cooperating profile rollers provided with screw flights exist. Such Picking devices are especially useful for crooked and drooping maize plants Corn on the cob is prone to failure and is prone to clogging. Also, doing the pistons only torn off the stalks, and the remaining maize stalks have to be subsequent operation can be smashed with a forage harvester in order to then go to Rotting into the ground to be able to be plowed under.

Devices are also known whose insertion members are controlled or at least movable Have tines in order to strip the long-handled cuttings - the corn stalks - from the insertion organs, otherwise they would clog in a very short time. The machine would clog and would have to during trapped stems and leaves are removed after long waiting times. This disadvantage will avoided by the known insertion organs, but it must be the higher wear, a difficult maintenance and, above all, curve control must be accepted.

The invention has set itself the task of providing a simple, failure-prone, single-row harvesting device to create that avoids the disadvantages of the known devices and to all occurring Combine harvester types and also on combine harvesters

This object is achieved by at least one arranged around one at least approximately vertically Pin rotatable, belt-driven and preferably equipped with prongs insert wheel, which with Part of its circumference limits the insertion mouth laterally and its drive belt in the stretched, The area facing the infeed auger removes and removes the crop from the inlay wheel.

According to a particularly advantageous embodiment of the invention, the insert wheel and engine are designed as an attachable unit and drivable from the reel shaft.

According to the invention, a buildable unit formed to form a tail unit limits together with the the insert wheel and the engine comprehensive unit laterally the insertion mouth.

According to another embodiment of the invention, several insert wheels can also be placed one on top of the other and be provided at a distance from each other, the over a single V-belt or over their several can be driven.

Further essential features of the invention emerge from the following description.

In the drawing, the invention is shown, for example, in several embodiments, and although shows
