Hybrid power high-speed rice transplanter and steering method thereof

Abstract

The invention provides a hybrid power high-speed rice transplanter and a steering method thereof. The hybrid power high-speed rice transplanter comprises a rice transplanter main machine, a power system and a walking system, wherein the power system is arranged on the rice transplanter main machine and drives the rice transplanter main machine to conduct rice transplanting operation; the power system comprises at least one engine and at least one electric energy generating device, wherein the engine drives the electric energy generating device to generate electric energy; the walking system isarranged on the rice transplanter main machine and comprises at least four vehicle wheels and at least four electric motors, wherein the electric motors drive the vehicle wheels to walk; and the electric motors drive the vehicle wheels on the left side and the right side to rotate at different kinematic velocity, and thus the steering of the walking system is realized.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a hybrid high-speed rice transplanter and a steering method thereof. Background technique [0002] The rice transplanter is a planting machine for planting rice seedlings in paddy fields. It not only replaces the process of manual planting, but also improves the efficacy and quality of transplanting to a certain extent, and realizes reasonable dense planting and standardized planting. It is beneficial to the mechanization of follow-up operations. According to the transplanting speed, it can be divided into ordinary rice transplanter and high-speed rice transplanter. [0003] High-speed rice transplanters of the prior art include fuel oil as power rice transplanters, electric motors as power rice transplanters and hybrid kinetic energy rice transplanters. The rice transplanter powered by a fuel engine is the most primitive type of rice transplanter. Generally speaking, the ...

AI Technical Summary

Problems solved by technology

When it is necessary to turn a large angle, such as turning around and turning, it is usually necessary to turn back and forth multiple times to walk, so the turning range is small and the efficiency is low, thereby slowing down the overall working efficiency of the rice transplanter

This rice transplanter of prior art in addition when turning, the damage of wheel to farmland is serious

When the rice transplanter is turning, the wheels on the inner side of the curve of the rice transplanter and the outer wheels rotate at the same speed, but the trajectories are different, which will damage the wheels and the transmission device of the wheels, and easily reduce the overall life of the rice transplanter

In addition, the driving method of the rice transplanter in the prior art relies on a single front wheel or rear wheel drive, and driving in a paddy field can easily cause the driving wheel to sink into the farmland, making it impossible to drive the rice transplanter.

[0006] For the electric rice transplanter in the prior art, when the rice transplanter is turning, especially when turning a curve with a large angle, due to the large steering resistance, the torque provided by the drive shaft to the outer wheel is insufficient, which causes the vehicle to walk when turning difficulty

Especially in narrow terrain, the rice transplanter in the prior art is limited by the steering range of the vehicle, and it needs to adjust the running direction many times to achieve the final steering

In addition, when the rice transplanter turns, the trajectories of the front and rear wheels are different, and the damage to the farmland is more serious than that caused when it goes straight.
