摘要

借鉴仿形技术的进步,本文介绍了一种创新的割草机横向仿形机构,以提高割草效率和适应地形的能力。它深入探讨了模仿原理和被迫情况。此外,还介绍了一种新颖的草坪保护靴设计,它能够以快速转换的方式调整割草高度。通过严格的有限元分析,该保护靴的结构完整性得到了优化。同时,还精心选择和设计了滚动轴和切割器,并建立了切割器的机械模型,以研究其运动和受力特性。此外,还设计了满足顶头所需功能的液压回路,并适当选择了关键液压元件。使用 ANSYS 对关键部件进行有限元分析,以验证和优化其结构强度。随后进行了原型测试和实地试验,结果表明割草机在平地和 25 度斜坡上的割草速度可达 0.85 米/秒,从而满足了割草速度的设计要求。模仿机构可适应不同的堤坝地形。值得一提的是,草坪保护靴的割草高度可分别调节为 10.4 厘米、12 厘米和 14 厘米,每个位置的高度调节范围约为 2 厘米,满足了割草高度调节的要求。此外,草坪保护靴不同位置之间的转换时间小于 5 分钟,实现了快速切换,提高了操作效率。此外,还使用配备剖面功能的割草机进行了割草均匀性测试。结果显示,仿形割草机的割草效果符合设计要求,证明了其在农业应用中的有效性和可靠性。

Design and Experiment of the Profiling Header of River Dike Mower
Drawing upon advancements in profiling technology, this paper presents an innovative lateral profiling mechanism for the header to improve mowing efficiency and the ability to adapt to terrain for river dike mowers. It delves into the imitation principle and forced situations. Furthermore, a novel lawn protection boot design has been introduced, capable of adjusting mowing heights with swift transitions. The structural integrity of this boot has been optimized through rigorous finite element analysis. Meanwhile, the rolling shaft and cutter have been carefully selected and designed, with a mechanical model of the cutter established to examine its motion and force characteristics. In addition, hydraulic circuits tailored to fulfill the required functions of the header have been devised, and key hydraulic components have been appropriately selected. Key components are subjected to finite element analysis by using ANSYS to verify and optimize their structural strength. Prototype testing and field trials are subsequently conducted, revealing that the mower can achieve a mowing speed of 0.85 m/s on flat ground and a 25-degree slope, thereby fulfilling the design requirements for mowing speed. The imitation mechanism adapts to different embankment terrains. Notably, the lawn protection boots offer adjustable mowing heights of 10.4 cm, 12 cm, and 14 cm, respectively, with a height adjustment range of approximately 2 cm for each position, meeting the requirement for adjusting mowing heights. In addition, the transition time between different positions of the lawn protection boots is less than 5 min, achieving rapid switching and operational efficiency. Furthermore, a mowing uniformity test is conducted by using a header equipped with profiling functionality. The results reveal that the mowing effect of the profiling header meets design requirements, demonstrating its effectiveness and reliability in agricultural applications.
