针对农田集中连片的建设要求以及高精度土地平整的特点,设计了一种农田激光测控精平机,该精平机采用双弹性扭杆独立调平系统,能够实现刀板两端的独立调整.地表平整精度的决定因素主要包括调平装置的竖直调整量和调整速度,该精平机有效地降低了刀板调整量;同时建立了调平系统的动作数学模型,对其进行了运动速度分析,确定了满足较高平整精度要求下的立缸调整速度.试验结果表明:该精平机能够很好地完成大面积农田高精度土地平整的农艺要求.

Focus on contiguous farmland for construction requirements and characteristics of high land leveling precision, a farmland laser measurement and control leveling machine is designed.To achieve the ends of the blades adjusted inde-pendently, the leveling machine employs independent leveling system of double elastic torsion bar.The determinants of leveling precision for surface flatness include vertical adjustment amount and speed of adjustment about leveling device. The blades adjustment is reduced by style of leveling machine, while establishing a leveling system moves mathematical model to analyze its movement speed.The vertical cylinder speed adjustment is determined to satisfy the requirement of high leveling precision.The results showed that the leveling machine can well complete the sooth operation of the whole farmland leveling for agronomic requirements.
