Description

GERMAN

Grain harvesters, especially combine harvesters and forage harvesters, are used in stony soils repeated operational disruptions due to stones picked up in combine harvesters the threshing unit (threshing drum and concave) and, in the case of forage harvesters, the cutting blades damage the chopping unit. There are already explanations for avoiding these malfunctions known in which in front of the threshing unit in combines and in front of the chopper of the Forage harvester trough-like depressions (stone collecting troughs) are provided that intercept the Stones should make possible. However, these designs have the disadvantage that the trough-like depressions Fill up with crop quickly so that on the one hand the stones introduced are not properly intercepted and on the other hand, the collecting troughs are emptied at short intervals must, which results in a great loss of time and valuable crops are lost at the same time.

According to the present invention, the disadvantages that occur in the known designs are to be be avoided. For this purpose, it is suggested, in the case of combine harvesters, behind the mower in front of the intake auger, about a few centimeters above the bottom plate of the infeed table, parallel to the Finger bar to mount a safety bar. This ensures that stones or foreign bodies, which are picked up with the mown fruit, just behind the mower in front of the mounted one The catching bar remains visible and can be easily removed at any time, which increases operational safety the harvester is increased.

In the drawing, the subject matter of the invention is as far as it is necessary for understanding the invention is required, shown in Fig. 1 and 2.

Fig. 2 a stone collecting bar on a forage harvester.

On the table 1 of the combine or forage harvester, behind the mower 2 in front of the intake roller 3, at a distance 4 above the floor panel 5, parallel to the finger bar, the stone collecting rod 6 is attached-stone collecting device

brought, which is attached to the side plates 7 of the infeed table 1. The stone collecting rod 6 can be in a slot guide 8 are adjusted in their height, so that the distance 4 accordingly changes. All stones or other foreign objects sliding over the mower of the harvester remain lie behind the finger bar, as the stone collecting bar feeds the foreign bodies to the threshing unit or in the case of the chopper to the knife disc.

Claims (2)

Claims. 1. Stone collecting device for harvesting machines, especially for combine harvesters and forage harvesters, characterized by a crossbar mounted behind the mower at a distance above the bottom plate of the inlet parallel to the finger bar. 2. Stone collecting device for harvesting machines according to claim 1, characterized in that the The height of the cross bar provided behind the mower above the bottom plate of the inlet and its distance from the mower can be adjusted in parallel. 1 sheet of drawings
