Description

  The present invention relates to a hybrid combine equipped with an engine and an electric motor as power sources.

An engine is mounted as a power source for the combine, but a so-called hybrid combine that combines an electric motor is considered for the purpose of saving fuel and reducing noise.
For example, in the invention described in Patent Document 1, a harvesting operation is performed with the engine fixed at a rotational speed near the maximum output, and a surplus output of the engine during the harvesting operation is converted into electric power and stored in a capacitor. The electric motor is driven by the electric power stored in the vehicle to run inside and outside the field.

  The invention described in Patent Document 2 is a combine provided with an engine that drives a traveling device and an electric motor, and stores electric power generated by a generator that generates electric power with the driving force of the engine in a capacitor and is stored in the capacitor. Power is used as a part or all of the power source of the combine.

  In the invention described in Patent Document 1, since the engine rotational speed is always driven near the maximum rotational speed where the combustion efficiency is high, fuel can be used effectively, but the battery charged with the remaining capacity of the engine Even when the battery is fully charged, the engine rotation speed is maintained at the maximum rotation speed, so that there is a problem that fuel is consumed more than necessary and fuel consumption is reduced.

  Further, the invention described in Patent Document 2 can reduce the amount of exhaust gas emitted from the engine because the electric motor can supplement the engine output even if the engine output is reduced. And the noise is relatively small.

However, in these conventional technologies, the electric power stored in the capacitor is only a part of the energy obtained by burning the fuel, and the fuel consumption cannot be effectively reduced.
Therefore, in the present invention, not the combustion energy of the fuel, but the harvesting grain of the combine, the kinetic energy or the potential energy of the discharged grain is regenerated as electric power and stored in a capacitor, and this power is used for threshing by the engine.
