Design and Experiment on Chassis Structure for Highland Gap Field Management
-
Abstract: With development of agricultural modernization,field management machinery is of great significance to promote stable development of agricultural mechanization in China.Aiming at agronomic requirements of planting crops such as rice,rapeseed and tobacco in southern paddy fields,a field management operation chassis which can be coordinated and adjusted with different crops,different spacing,different periods of crops and different growth heights was designed.Overall structure of gap operation chassis which was suitable for field management function of southern field was determined.Structure design of adjusting mechanisms such as wheel distance,axle distance and ground clearance was carried out,and strength indexes of key components were verified by CAE method.At the same time,the stability and pass ability of operation chassis were analyzed by theoretical calculation method,and performance of whole machine was tested by field and field experiments.Results showed that stability and pass ability of the work chassis meet design requirements.
