Study on the Adaptability and Optimization Design of Sprinkler Vehicle of Winch Sprinkling Irrigation Machine

研究了绞盘式喷灌机喷头车的结构和适应的作物高度与作业场合,根据存在的适应性问题及现实需求对喷头车结构进行了优化改进。对比分析了多种方案,确定了最优方案为齿轮齿条结构,设计了增高装置。计算了增高装置适应的高度范围和减速箱输出扭矩。详细说明了增高装置的工作原理、使用方法;计算了减速箱选择的理论依据,试制了样机,并对样机进行了多轮田间试验,提出了使用注意事项。

The structure,the suitable crop height and the operation occasion of the sprinkler vehicle of the winch sprinkling irrigation machine were studied in this paper.According to the existing adaptability problems and practical needs,the structure of sprinkler vehicle was optimized and improved.By comparing and analyzing various schemes,the optimal scheme was confirmed as pinion and rack structure,and the heightening device was designed.The suitable height range of the heightening device and the output torque of the reducer were calculated.The working principle and using method of the heightening device were explained in detail.The theoretical basis for the selection of reduction gear box was studied,the prototype was trial-produced,several rounds of field tests were carried out on the prototype,and the precautions for use were put forward.
