Quick coupling device for the cutting table of combine harvesters

The innovation relates to a device for automatic coupling and uncoupling of the cutting table from the elevator shaft of a combine harvester, where the cutting table is wider than the combine harvester and therefore uncoupled for road transport and transported separately, e.g. in a transverse position to the machine must become.

There are already known designs in which centering lugs in the upper area of the elevator shaft are arranged, which in connection with the assembly of the cutting table and elevator shaft fix both parts with appropriate recesses on the cutting table.

The disadvantage of these known designs lies in the fact that for a reliable connection screws are still required for both parts; however, this measure requires a great deal of time and is therefore uneconomical.

The present innovation has therefore set itself the task of eliminating these disadvantages and to create a coupling device that is simple, reliable and completely automatic to use is and works.

For this purpose, according to the innovation, the centering lugs known per se in the upper area are provided the connection point of the cutting table and elevator shaft in such a way that a real. Centering is achieved with a good and firm fit at the same time and that in the lower area a " Automatic locking device controlled from the driver's cab is preferably provided, which positively connects the cutting table with the elevator shaft. In this version so one man can easily and quickly couple and uncouple the cutting table.

In the drawings, an embodiment of the innovation is shown and described in more detail below. Show it

In the innovation according to the quick coupling device according to Figures 1 and 2, the elevator shaft 1 in his upper area two centering lugs 2, which are approximately flush with the scattering surface 3 and the adjacent Side surfaces 4 run. These centering lugs 2 consist of a box-shaped hollow profile and engage in corresponding counter bearings 7 on the rear wall of the cutting table 9. The plates 5 and 6 are used for reinforcement in the force application points.

For the lateral guidance of this centering 2 when coupling the baffles lo are used, which are from the lower cutting table limitation taper conically towards the counter-bearing openings 11.

An automatic locking device 11 is arranged on the underside of the elevator shaft 1, hydraulically, pneumatically or mechanically via claws or pins 12 in holders 13 on the rear wall of the cutting table 8 engages and firmly connects the cutting table 9 to the elevator shaft 1. In coupled State, the bolts 12 are pressed into the bearings 13 by springs 14! when loosening is through the hydraulic cylinder 15 the spring action is canceled and the pins 12 are withdrawn. You can now Lower elevator shaft 1 until the cutting table comes to rest on the floor and at Further lowering, the centering cams of the elevator shaft 1 are moved out of the bearings 7. When coupling, the opposite direction is used.
