Experimental research influences of seeds on the movement of the seeds on their non-perforated vibration frictions

Abstract

The article presents the results of experimental studies of the effect of crop seed interplants on their movement on the working plane of a vibration friction machine. The studies were performed on seed mixtures of sunflower and soybeans, which are very different in their physical and mechanical properties: shape, roughness and elasticity.
Experimental studies were conducted in three existing modes of movement of seeds on the working plane: inseparable, tear-off and shock. Since the shock mode of movement of seeds can only provide mechatronic vibrating multi-plane seed cleaning machine, this machine was used in the work. The working body of this machine are four blocks of non-perforated friction planes (25 pieces in each block), which carry out parallel technological processes of separation of seed mixtures in three modes of movement (inseparable, tear-off and shock).
As a result of the experimental studies, the effect of the interconnections of the components of the seed mixtures with each other on their movement along the separating planes of the vibrating seed-cleaning machines has been established. This influence is significantly dependent on the physical and mechanical properties of the seeds and their mode of motion on the separating planes. Studies have shown that the most significant effect of seed interference on its movement is observed in a continuous mode of movement and for seeds of flat shape with the highest roughness and low elasticity.
According to the results of the experimental studies, it is possible to conclude the need to take into account the influence of seed interconnections with each other in mathematical modelling of seed movement on the separating planes of vibrating friction machines and especially in the study of the motion of flat, rough and inelastic seeds in a continuous motion.
