Description

GERMAN

The hammering at the corners of the field takes place in the case of grain harvesting machines pulled by draft animals in such a way that that the machine turns on the main wheel and the small wheel runs backwards. The machine can then drive full width into the grain.

Such a short turning is not possible with harvesting machines pulled by tractors. The turning can be done in several ways. The machine travels a little over the field and is reversing pushed and turned; or the machine runs a right-hand loop of (with left-hand cutters) 270 °. In both cases, the machine can then drive into the grain at full width. The machine can but also drive out of the grain, then turn by 90 ° and drive with increasing width back inside. The first two types of impact are very cumbersome. If not a sheaf collector is available, a lot of sheaves must be set aside, and there is also repeated driving over harmful to the undersown crops. In order not to have to drive out the harvester to turn and that To speed up mowing, round off the corners with a scythe. After a few detours However, these curves disappear again, and it has to be mowed continuously by hand. the The reason for this lies in the constant cutting width of the harvesting machine. To get the curves, a considerably larger cutting width would be required when driving around the curve than when driving straight ahead. This is shown in the drawing FIG. Lanes 1 and 2 have the curves there required cutting width so that the curves are retained.

The following strips 3 and 4 have the same cutting width in the curves as in the 3s Straight lines, the curves then become smaller with each subsequent trip and would eventually disappear. In the path 5, the harvesting machine can no longer turn in the grain and must drive out. In addition to the web 7, this creates a point (hatched), which is the same size in the The following bypasses are retained, if not mowed by hand.

A device is already known which is intended to eliminate this disadvantage, namely by automatically pivoting out the divider arranged at the outer end of the cutting mechanism. The main advantage of this device is that the cutting width is not smaller there than when driving straight ahead, which is the case with laterally rigid dividers. However, in order to achieve the necessary cutting width at the curves, which increases by about 40%, the divider would have to be swung out so far that part of the harvesting machine for grain is detected

Albert Meister, Dingden (Westphalia),
has been named as the inventor

Stalks would be torn down and run over by the little bike.

In order to have a sufficient cutting width when driving around the curves, according to the invention the end of the straw arranged at the inner cutter about an approximately perpendicular axis opposite to the Dividers can be pivoted. Both then diverge like scissors. The straw lifter, whose Pivotability is known per se, advantageously has its pivot far behind the Cutting unit, for example at the rear edge of the harvesting machine, and is arranged such that it is at Swiveling outwards releases a few fingers and knife blades of the cutting unit.

The device is shown schematically in FIGS. 2 and 3 in plan view.

Fig. 2 shows the harvesting machine driving straight ahead,

Fig. 3 when driving around the curves.

The harvesting machine shown as a binder is on the trailer rail 8 of the tractor 9 with her Drawbar 10 attached. In addition, a pull rod 11 is arranged in a known manner, which with an angle lever 12 is articulated on the harvester. By longitudinal movement of the pull rod 11 when Circumnavigating the curves is via the angle lever 12 with the connecting rod 14 of the divider 13 and opposite to this with the connecting rod 15 of the straw lifter 16 pivoted, with some fingers and knife blades 17 of the cutting unit are released, which when driving straight ahead (Fig. 2) from Straw lifter 16 are covered.

Claims (4)

Patent claims: 1. Harvesting machine for grain that can be attached to a tractor with a stalk lifter on the inner cutter end and one arranged at the outer cutter end, around a 709 908/56 vertical axis pivotable divider, which is so swiveled when cornering that it grips a point much more grain to be mowed than corresponds to the width of the cutting unit, characterized in that the straw lifter (16) rotates in opposite directions about an approximately vertical axis is pivotable to the divider (13). 2. Harvesting machine according to claim 1, characterized in that for pivoting in opposite directions of the divider (13) and the straw lifter (16) a linkage (11,12,14,15) is used, which is attached to the Hitching rail (8) of the tractor (9) laterally next to the drawbar (10) of the harvesting machine in this way is connected that when driving around the field corners during work, the tips of the divider (13) and the straw lifter (16) are pivoted outwards. 3. Harvesting machine according to claim 2, characterized in that the linkage consists of one to the Hitch rail (8) of the tractor (9) hinged drawbar (H), an angle lever (12) and One connecting rod (14 and 15) each moving the divider (13) and the straw lifter (16) consists. 4. Harvesting machine according to one of claims 1 to 3, characterized in that the pivot axis of the stalk lifter (16) is far behind the cutting unit, for example on the rear edge of the harvesting machine, and is arranged in such a way that that when pivoting the straw lifter (16) outwards some fingers and knife blades (17) of the cutting unit are released.
