Background
The transplanter is a common agricultural machine, and can quickly complete the transplanting operation of farmland with the assistance of the transplanter.
The power source used by the current rice transplanter is an internal combustion engine, and the internal combustion engine type rice transplanter has more problems, on one hand, the internal combustion engine type rice transplanter works by using fuel oil, and more pollutants exist in discharged gas due to limited utilization rate of the fuel oil, on the other hand, the internal combustion engine type rice transplanter is mostly in a low-efficiency area when working, and the whole working efficiency is lower.
Clean energy and green agriculture are the current development trends of agriculture. Further, when the power source of the rice transplanter is an internal combustion engine, an HST (hydraulic Transmission) Transmission mechanism is often used, and the HST Transmission mechanism has a small low-speed torque.

Referring to FIGS. 1 to 3, a hybrid rice transplanter 1 and a range extender 51 for the hybrid rice transplanter 1 according to a preferred embodiment of the present invention are illustrated.
The hybrid rice transplanter 1 uses electric power as a power source, and the range extender 51 can assist in supplying electric power.
Specifically, the hybrid high-speed rice transplanter 1 includes a body 10, a traveling unit 20, a rice transplanting operation unit 30, a driving unit 40, a power supply unit 50, and a control unit 60, wherein the traveling unit 20, the rice transplanting operation unit 30, the driving unit 40, the power supply unit 50, and the control unit 60 are mounted to the body 10, respectively.
The walking unit 20 supports the vehicle body 10 to drive the vehicle body 10 to walk. The transplanting operation unit 30 is used for transplanting seedlings to the ground, and the transplanting operation unit 30 may be located at the front or rear of the vehicle body 10.
The traveling unit 20 is drivably connected to the driving unit 40. The seedling-transplanting work unit 30 is electrically connected to the control unit 60. The control unit 60 includes at least one ECU controller.
The power supply unit 50 includes a range extender 51 and a battery 52, wherein the battery 52 is electrically connected to the range extender 51, wherein the range extender 51 includes an internal combustion engine 511 and a generator 512, wherein the internal combustion engine 511 converts internal energy of fuel into mechanical energy, and the generator 512 converts mechanical energy into electrical energy. The battery 52 is electrically connected to the generator 512, and the generator 512 transmits the generated electric power to the battery 52 and then is used by other power-requiring components of the hybrid rice transplanter 1 through the battery 52.
Due to the existence of the range extender 51 in the power supply unit 50, the volume of the battery 52 can be designed to be small, that is, the battery 52 can be light-weighted. Specifically, when the power supply unit 50 supplies power and the amount of power in the battery 52 is about to be exhausted, the range extender 51 may generate power to continuously supply power to the battery 52, so that the battery 52 does not need to be designed to have a large mass or volume. The range extender 51 may supplement the battery 52 with electric energy in a timely manner so that the mass or volume of the battery 52 can be reduced.
Further, the hybrid rice transplanter 1 includes a steering unit 70, wherein the steering unit 70 is implemented as an electrically controlled steering member. The control unit 60 comprises a steering control module 61, wherein the steering unit 70 is electrically controllable connected to the steering control module 61. The steering unit 70 is used to control the steering of the traveling unit 20.

The internal combustion engine 511 of the range extender 51 is speed controllably connected to the range extender control module 64 and the generator 512 of the range extender 51 is torque controllably connected to the range extender control module 64. After the internal combustion engine 511 of the range extender 51 reaches a required rotation speed point according to an input signal, the range extender control module 64 controls the magnitude of the power generation torque of the generator 512 according to the magnitude of the required power generation amount of the generator 512, thereby realizing the control of the power of the generator 512.
The steering unit 70, the brake unit 80 and the transplanting operation unit 30 of the hybrid rice transplanter 1 are all electrically operated and controlled, so that a large number of mechanical transmission structures of the conventional rice transplanter driven by an internal combustion engine 511 are reduced, and the whole hybrid rice transplanter 1 has high efficiency and low failure rate.

When the load capacity of the hybrid rice transplanter 1 is large, the hybrid rice transplanter 1 can be switched to the second operation mode to operate. When the hybrid rice transplanter 1 is stuck in a farmland, the hybrid rice transplanter 1 can be switched to the second operation mode for operation.
When the hybrid rice transplanter 1 travels on a flat ground, the hybrid rice transplanter 1 can be switched to the first operation mode to operate.
When the power of the battery 52 of the hybrid rice transplanter 1 is insufficient, the hybrid rice transplanter 1 can be switched to the third operation mode.
In other embodiments of the present invention, the hybrid rice transplanter 1 has two operation states, a first operation mode in which the battery 52 of the power supply unit 50 supplies power to the drive unit 40, the rice transplanting work unit 30, the steering unit 70, the brake unit 80, and the like, alone, and a second operation mode.
