Abstract


This article is based on no-till planter suction seeding device as the research object , the first study of conservation tillage farmland land face excitation caused by the planter seeding device testing and analysis to identify the frequency of the excitation of to select the appropriate parameters of the exciter and vibration the seeding performance test of air-suction seeding device . Then through orthogonal test affect the suction - tillage planter quality vibration frequency , vibration acceleration , vacuum pressure test three factors research . Ultimately the relationship between the planter suffered excitation frequency , amplitude , vacuum pressure and seeding performance . The test results show that : the primary and secondary relationship factors affect corn seeding qualified rate of acceleration , frequency , pressure . Primary and secondary relationship factors affect the pass rate of sunflower seed metering pressure , acceleration , frequency . Primary and secondary pass rate factors affecting cotton seed metering vacuum pressure of the vacuum chamber , the relationship between the frequency of the vibration acceleration . Corn , sunflower , cotton three different seed bulk density seeding performance analysis can draw the following conclusions : the seed metering device row bulk density higher density seed , seeding performance will be affected by the decline and exciting , the seeding devices in row bulk density is small , the accumulation of low -density seed , seed metering device seeding performance have increased due to the excitation effect . Especially sunflower Dimensions such irregular bulk density, the smaller the seed , the effect is more apparent.
