The Testing Stand Design and Parameter Determination of Pneumatic Seed Metering Device of No-Till Seeder

Abstract:

testing stand that is able to imitate the vibration of seeder field surface stirred up is designed to analyse the effect of vibration on the seed metering function of pneumatic seeder. The signal of vibration data is collected by tape recorder on the testing spot in testing process and then the vibration signal is analysed. A conclusion is reached based on the analysis of testing result that: the trait vibration of seeder is an approximate periodic function, which may be approximately simulated with sine exciting signal; the trait vibration frequency of seeder ranges form 0 to 68 Hz, the maximum acceleration of vibration makes 25m/s², and the minimum excited vibration thrust of vibration exciter is 500N. A testing stand for seed metering is designed by taking these parameters as the criterion to simulate field surface excited vibration and analyse the seed metering dynamic characteristic of seed metering device.
