A reaper of a self-propelled combined harvester comprises a platform with a cutterbar and shoes, connected with an inclined chamber, on which a lifting mechanism and a balancing mechanism with springs are arranged, and on an axle a drum with a cam and flexible rods, fixed thereon, is mounted freely. The end of one of said control-rods is connected with the platform of the reaper, and that of the other one with the springs of the balancing mechanism. According to the useful model, on the inclined chamber an additional drum with a cam and flexible rods, fixed thereon, is mounted freely. The end of one of said control-rods is connected with the platform of the reaper, and that of the other with the second spring set of the balancing mechanism. In doing so one spring set is connected to a flexible rod, wound on the additional drum, rigidly fixed on the joint axle with a star gear, embracing a chain, connected with the other spring set and a hydraulic cylinder hydraulically connected with a hydrodistributor. A slide valve of said distribution valve is connected with a rotary lever to connect the platform with a feeling shoe. |
