Studies On The Level Ing System Of Tillage Inplement Based On Tractor Three-Point Suspension System

Agricultural mechanization is the central link in the development of agricultural modernization. The tractor as the advanced production tool plays an important role in improving agricultural productivity and peasant’s living standard. The inclined walking of tractor caused by the potholes or slope in farmland, when the tractor operation. As the tractor implement part and the tractor is relatively fixed so when the tractor implement during operation, that could lead to the implement tilt with the tractor tilt and it may not be enough. At present, the tractor implement part still in the stage of manual mechanical adjustment, it waste time and energy and can’t make real-time leveling. It is go against the development of agriculture automatic turned to automatization and intelligentization in China. Therefore,this paper’s research on the tractor three-point suspension tillage implement for realize land leveling, improve land tillage and promoting agriculture development has important practical meanings.It also has a wide application prospect in the field of agriculture construction and land development consolidation.Firstly, this paper has analyzed the development of the domestic and foreign research on the automatic leveling system to ensure the research target and content The1GDZ-150crawler rotary cultivator tractor as the research platform in the design and make the technology roadmap. Analysis on the mechanism part of tractor implement to determine the feasibility of implement leveling system.Secondly,according to the research content, we designed the control system and hydraulic system of tractor implement automatic leveling system and and analyzed the problem of this system.With the improvement of hydraulic system to ensure stabilize work on hydraulic system. In the leveling process, a terrible influence on tilt sensor data acquisition in the external environment especially complex environment, Therefore, through the data research using the filtering algorithm and temperature compensation algorithm to reduce the vibration noise and influence on data acquisition about environmental temperature. At last, with a series of static and dynamic farmland experiment to verify the feasibility and reliability of the automatic leveling system about the tractor implement. Because of the limited time, there are some deficiencies in the design and this paper aims at these deficiencies to put forward the corresponding improvement opinions.
