Structural Design And Experimental Study On Rapeseed Sowing Test Bench

Rapeseed is an important oil crops, its production situation not only affects the income of farmers, the development of oil crops, but also with the stable development of the national economy and society are closely related. The rapeseed planting machinery play a crucial role in rapeseed production. For the current research status of rapeseed cultivation machinery and development needs, designed and produced rapeseed sowing test stand that composite uniform and sow two kinds of functional parts, It provides a theoretical basis.for the late production of rapeseed sowing machineThe study measured the physical and mechanical properties of the rapeseed, got its grain weight, friction angle, angle of repose and the average diameter, it provides technical parameters to design rapeseed spreader structural.Preferably a uniform core components seeder of Seed spreader,and experimental study of the uniformity of seed, seed quantity relationships with seed shaft speed. T Test showed that coefficient of variation of uniformly device in seed shaft speed when10-80r/min in line with national technology standard,Its size is12.7%-20.6%, At the same mathematical model of the unit has been got under the kind of volume and speed of seed shaft speed.By univariate and multivariate orthogonal experiment to study the sow device uniformity,the results showed that:seed shaft speed, disk speed and transmission speed with speed (forward speed analog equipment) angle adjustment plate angle are the main factors affecting sowing uniformity, and got even when the rotation speed of50species, sow disc speed is80, angle adjustment plate angle is50°and the forward speed of machines under condition2, sow uniformity is best. Its sowing uniformity coefficient of variation is38.9%, to meet the design requirements.The institute designed to sow rapeseed test bed provides the design basis for the development of rapeseed spreader,Theoretical analysis and experimental parameters are derived from rapeseed, The research results will also be suitable for other small spherical particles sow study material.
