Self-propelled combine harvester

The invention relates to a self-propelled combine harvester with a side of the cutting table or the reel, forward-extending dividers, which are vertically via support arms hinged to the mower table at the rear ends are pivotable.

By pivoting the dividers vertically, they can be adapted to the conditions prevailing in the field will. In order to be able to participate in public road traffic with self-propelled combine harvesters, the legislator requires that the mower table with reel is raised to an upper transport position, the cutter bar with a protective strip covered and the divider and - if available - the grain erector removed from the cutting table to the Eliminate the risk of accidents as much as possible. The claim is justified when you consider that at the front At the end of the divider, the so-called divider tips sit, which in a sense impale everything that is in the driveway of the Combine arrives. The operator of the combine harvester is therefore forced to comply with the above-mentioned legal requirements when driving on the road To meet requirements. But now it is precisely

and dismantling the dividers and possibly the lifting pole is not only annoying and cumbersome, but it becomes because of the The associated workload is often not carried out at all, so that there is a considerable risk of accidents remain.

The object of the invention is to provide an effective remedy here. This provides that with a self-propelled Combine of the type mentioned in addition to the divider support arms approximately at the level of the front edge of the cutting table a substantially vertical axis can be folded inwards. This makes it possible to use self-propelled combine harvesters to take part in public road traffic without having to remove the dividers from the machine, rather, their support arms only need to be folded inwards when the mower table is raised. In the folded position the divider cover these or their support arms and the cutter bar of the cutting table, so that the previously required Protective strip for the mower knife can be omitted. The advantages achieved with the invention therefore exist in particular in that the previously necessary mounting and dismantling of the dividers and the cutter bar protective strip are omitted, hence the addition The set-up time to be expended is now used economically can be, while at the same time the risk of accidents is reduced to a minimum.

In an advantageous embodiment of the invention are at the

Kink of the department arms is provided with two claw-like or fork-like interlocking coupling pieces attached to each arm part, which have at least one common Articulated connection are connected to each other. This allows the divider arms to be folded down very easily.

An embodiment of the invention is shown in the drawing and is described in more detail below. It demonstrate:

On the mowing table 1, not shown in detail, a reel 2 and a cutter bar 3 are arranged in a known manner. ^{A divider 4, 4 1 is provided} on both sides of the cutting table 1 and a grain erector 5 is also provided on one side. At the front ends of the dividers 4, 4 ¹ sit the so-called divider tips 6, which are attached to support arms 7, 7 ', by which the dividers 4 are therefore carried. The support arms 7, 7 ¹ are at their rear ends

so hinged on the mower table that they together with the Dividers can be pivoted vertically.

According to the invention, articulated bearings 8 are now arranged on the divider support arms 7, 7 'approximately at the level of the front edge of the mower table 1, via which the support arms 7, 7 ¹ can be bent inward. As can be seen from FIGS. 2 and 3, the articulated bearing 8 consists of two coupling pieces 9, 10 which are fixedly arranged on the w arm parts 14, 15 of the support arms and which mesh with one another via fork-like or claw-like coupling parts 11, 12 and via bolts 13 are connected to each other. In the illustrated embodiment, two hinge pins 13 are provided. This has the advantage, on the one hand, that in the non-kinked position of the support arms 7, 7 ', the bolts serve as a locking device and, on the other hand, the front arm part 15 can be bent both inwards and outwards-backwards, if one bolt 13 is pulled out of the coupling parts.

In Fig. 4, the two arm parts 14, 15 of each support arm 7 and 7 ^{1 are} connected by a tension spring 16, which holds the bent arm part 15 securely in the right-angled bent position, as shown with dashed lines.

In order to use the grain erector 5 also this

to be able to bend inward, it is at the level of the buckle bearing 8 of the facing Abteilerannes 7 also with a hinge part Mistake. As indicated in FIG. 1, this consists preferably of a hinge 17.

The invention allows manifold changes within the scope of the claims. So the articulated bearing of the divider arms 7, 7 ' can also be formed directly by the arms if they have, for example, different diameters and in the arm with the larger diameter on the inside, an adjustment of the other arm is possible Slot is provided. The securing of the buckled divider arms can also be done in other ways, for example can be achieved by an indentable lock arranged on the mower table.
