TECHNICAL DEVELOPMENT OF GRAIN FLOW SEPARATION DEVICES

It wos established that the technical development of grain flow dividers should follow the laws of the development of technical systems proposed by G.S. Altshuller in the theory of solving inventive problems. The main stages of research of devices for grain flow separation are shown. The initial necessity of creating a separate device for dividing the grain flow is shown. The exit from the grain pipeline system is needed to create a new system for the qualitative separation of grain flow. The necessity of a stabilizing capacity and the principle of auto-regulation - maintaining the grain layer in a given range is substantiated. The further development of this system is aimed at simplifying the design and fastening of the device, and the principle of auto-regulation is carried out with the help of slot holes. At the third stage of the study, the principle of transition to the suprasystem was applied – the divider is part of the grain pipeline, and the stabilizing capacity is absent as an independent device, and its function is performed by part of the grain pipeline. The principle of auto-regulation still performs slotted holes. It is established that the slotted holes reduce the flow characteristics of the divider, which can lead to clogging of the grain pipeline. The solution to this problem situation is the cascading placement of slot holes. The resulting device is a solution to the problem of qualitative separation of grain flow in grain cleaning technologies.
