Arable land due to the complexity of the mountainous terrain , small and scattered , ground elevation , agricultural machinery in the mountains job is more difficult than in the plains of the job ; the same time , due to the narrow road between the mountains , bumpy , making the mountain mechanical transport has become a problem . In recent years , the research and development of mountain agricultural machinery has become the focus of the Chinese agricultural engineering sector . An easy to operate , good stability, and mountain climbing ability and obstacle clearance capacity of agricultural machinery , has important practical value . The paper mountain mechanical stability insufficient , relying Shaanxi Province tobacco bureau project - \miniature farmland machine , and the completion of certain parts of the design . Traction performance test quantitative analysis of the track structural parameters on the performance of the aircraft attached at the prototype the optimal combination come within the scope of the study , and provide guidance for further reform of the aircraft . The main contents of this paper are as follows : (1) in the the original 1YG orchard clean tillage machine based on the characteristics for mountain operating environment , designed with hydraulic leveling device crawler walking system . (2) designed to balance the partial two-way balance of traction shovel . ( 3 ) completed the design and calculation of the hydraulic system , as well as the selection of hydraulic components . (4 ) provide a platform for the whole three-dimensional modeling , finite element analysis of the aircraft parts and further improvements . (5 ) Mountain Micro-farming machine prototype trial . ( 6 ) The traction the adhesion performance test , research track structure parameters on the performance of the aircraft attached . Tracked by orthogonal experimental design to study the mountain micro- farming machine structural parameters including track width, track support segment length and grouser machine traction adhesion properties , and obtain the optimal combination of the three parameters in the test range . The test results show that the adhesion grouser grouser exist to improve adhesion of 26.64% ; the best combination of track structure parameters : track support segment length 1020mm, the crawler width to 125mm the grouser height to 28mm . The main indicators of the aircraft : ground clearance adjustable between 136-336mm , Working width 30cm, designed tillage depth 25cm, maximum traction 3300N .
