RESEARCH ON SEED SEPARATION PROCESS ON A GRAVITY-CASCADE SEPARATOR

Different designs of separators are used for separating seeds. The principle of separator operation is based on various physical, mechanical and aerodynamic properties of seeds. Gravitational separators are promising because energy is not spent on separation process in this type of separators. A gravity-cascade separator was proposed, in which the separator sections are connected like “scissors”. The sieve length was theoretically justified, taking into account the condition for passing a small fraction of seeds into the sieve holes. The influence of sieves tilt angle and seed flow rate from hopper on the quality index of separation process was studied experimentally

Analysis of separator operation in difficult harvesting conditions

The importance of harvesters’ separators for efficiency and quality of work is shown. Using flax as an example, dependences were obtained for calculating the load on the stem feeders and the effect of the separator on the unevenness of the soil. A decrease in the performance indicators of the unit when the separators deviate from the working position has been experimentally confirmed. The conditions for increasing the efficiency of their work have been determined.
