Control method for rear four-wheel-drive land leveler and rear four-wheel-drive land leveler
The invention discloses a control method for a rear four-wheel-drive land leveler and the rear four-wheel-drive land leveler. Front wheels of the rear four-wheel-drive land leveler are provided with rotating speed sensors and angle sensors, the front end of the rear four-wheel-drive land leveler in the length direction is provided with a scraper knife, and when the front wheels of the rear four-wheel-drive land leveler steer, the real-time rotating speed of the front wheels of the rear four-wheel-drive land leveler is obtained in real time; acquiring a steering angle of a front wheel in real time; judging whether the front wheel slides or not according to the real-time rotating speed and/or the steering angle; if the front wheel slides, the set height of the scraper knife is controlled and adjusted, whether the front wheel slides or not is judged again according to the real-time rotating speed and/or the steering angle, and if the front wheel is still in the sliding state, the set height of the scraper knife is controlled and adjusted again till the front wheel does not slide, and the rear four-wheel-drive land leveler continues to work normally. Compared with manual adjustment in the prior art, the front wheel sliding adjustment efficiency is effectively improved, time and labor are saved, and potential safety hazards caused by front wheel sliding adjustment can be effectively avoided.
本发明公开了后四驱平地机用控制方法及后四驱平地机，后四驱平地机的前轮设置有转速传感器和角度传感器，且后四驱平地机沿长度方向的前端设有铲刀，当后四驱平地机的前轮转向时，实时获取后四驱平地机的前轮的实时转速；实时获取前轮的转向角度；依据实时转速和/或转向角度判断前轮是否发生滑动；若前轮发生滑动，则控制调整铲刀的设置高度，并再次依据实时转速和/或转向角度判断前轮是否发生滑动，如若前轮还处于滑动状态，则再次控制调整铲刀的设置高度，直至前轮不滑动，后四驱平地机继续正常工作。相对于现有技术采用人力调整而言，有效提升调整前轮滑动的效率，且省时省力，能够有效避免调整前轮滑动造成的安全隐患。
