| Western region is one of the important agricultural origin of inland, due to the harsh natural environment and farming irrational and unscientific nature, eventually leading to low agricultural production in the western region, directly restricts the western economy. Due west wind, tillage surface realization, Eased wind erosion on soil tillage sowing technology is the best way to achieve sustainable development of the western region of Agricultural Sciences.Air-suction vibration generated when tillage planter no-till farming on the surface, no-till planter seed box Suction impact on the establishment of vibration measurement system. For air-suction tillage planter in the open field trials inconvenience cable transmission characteristics of the application, using the method to measure the vibration acceleration sensors designed an integrated wireless transmission technology and the vibration signal acquisition and analysis of vibration measurement systems. Matlab analysis and processing the collected data signals. Conducted a mathematical model.Experimental results show that: the system is good in the field test stability, strong anti-jamming capability, the bridge a wide range of data transmission, convenient and practical, field vibration test provides air-suction tillage seeder for convenience; get through the collected signal analysis the,, air-suction tillage seeder mainly for vibration, increasing the speed of the low-frequency vibration intensity with enhanced, while the direction of vibration, trenching depth and ridge also as a test indicator to determine air-suction gas till planter vibration suction Seed is mainly determined by the vibration direction and forward speed and vibration intensity increases linearly; derived mathematical model for vibration, the vibration characteristics of air-suction device tillage planter seed planter structure mainly by characteristics, job forward speed, distance, soil seed with soil between the surface roughness and soil sticky decision. |
