The accelerator pedal 50 may be an accelerator pedal of a conventional structure, that is, the accelerator pedal is connected to an accelerator cable through a transmission mechanism, the accelerator cable is connected to an accelerator pull rod of an engine, when the accelerator pedal is stepped down, the transmission mechanism drives the accelerator pull rod of the engine to move through the accelerator pull rod, so as to increase the accelerator of the engine, and when the accelerator pedal is released, a return tension spring connected to the accelerator pull rod drives the accelerator pedal to return to reduce the accelerator of the engine, for example, an accelerator pedal in the background art of a combine harvester and a foot accelerator device thereof disclosed in chinese patent document CN102887071B (application No. 201210389439.9) is an accelerator pedal of such a conventional structure.
