基于传感技术的水田旋耕机平地系统的设计与试验
|
摘要
针对现有水田旋耕机在耕作时机械的倾斜和振动会导致耕整后的地表平整精度低、可控性差等问题,基于倾角传感控制技术设计一套与水田旋耕机相匹配的平地系统,通过液压控制和控制器控制相结合的方式实现平地系统的水平调节功能。田间试验结果表明:基于倾角传感技术,具有自动调节水平功能的水田旋耕机平地系统耕整平地性能稳定可靠。耕整后的平整度为2.20cm,高差分布为81.82%,相比水田旋耕机,平整度改善34.3%,高差分布提高19.4%,且能满足水稻种植的农艺要求。
To solve problems including low leveling precision and poor controllability etc.of paddy field rotary cultivator after plowing caused by tilting and vibration while farming,a set of leveling system consistent with paddy field rotary cultivator was designed on the basis of tilt angle sensor control technology.It realized leveling regulation function by combining hydraulic control with the controller control.The results of field trials showed that the working performance of field rotary cultivator leveling system based on tilt angle sensor technology was practical with its automatic leveling regulation function.The flatness after plowing Sdwas 2.20 cm,with elevation difference distributionβof 81.82%.Compared with field rotary cultivator,the field surface roughness was 34.3%and the elevation difference distribution increased 19.4%,indicating that it can basically meet the agricultural requirement of rice planting.
