摘要

丘陵和山区的小型水稻插秧机面临着适用机具少、插秧效果差、大型插秧机在小田块的适应性和效率低等问题。针对这些问题,设计了一种四行小型水稻插秧机,由发动机驱动,链条传动。机器结构主要由机架、发动机、水田轮、秧盘、插秧机构、换向变速箱和电磁离合器组成,总重量仅为 50 公斤,便于运输和操作。使用 MATLAB 对插秧机构进行运动学模拟和分析,绘制秧针位移图和插秧机构运动特性曲线。采用 ANSYS 软件对关键部件进行有限元分析,以确保其满足操作要求。实验研究以插秧速度为实验因素,以浮动率和缺插率为测试指标。结果表明,在规定的插秧条件下,上浮率稳定在 2.9%左右,缺插率稳定在 4.8%左右。这些结果表明,所设计的小型插秧机能有效满足丘陵地区水稻插秧作业的要求。

MATLAB-BASED DESIGN AND ANALYSIS OF SMALL RICE TRANS-PLANTER IN HILLY AREAS
A small-scale paddy rice transplanter for hilly and mountainous areas faces issues such as few suitable machines, poor transplanting results, and low adaptability and efficiency of large transplanters in small fields. To address these problems, a four-row small-scale paddy rice transplanter was designed, driven by an engine with chain transmission. The machine structure mainly consists of a frame, engine, paddy field wheels, seedling tray, transplanting mechanism, reversing gearbox, and electromagnetic clutch, with a total weight of only 50 kg, facilitating transportation and operation. MATLAB was used for kinematic simulation and analysis of the transplanting mechanism, plotting displacement diagrams of the seedling needles and motion characteristic curves of the transplanting mechanism. ANSYS software was employed for finite element analysis of key components to ensure they meet operational requirements. Experimental studies were conducted with transplanting speed as the experimental factor, using floating rate and missing insertion rate as test indicators. Results showed that under specified transplanting conditions, the floating rate stabilized at around 2.9% and the missing insertion rate at approximately 4.8%. These findings indicate that the designed small-scale transplanter can effectively meet the requirements for rice transplanting operations in hilly areas.
