JUSTIFICATION OF THE CONSTRUCTION AND WORKING PRINCIPLE OF THE VIBROASPIRATION SEPARATOR

Abstract

The paper is devoted to the study of the oilseed crop separation approach. The proposed design scheme of the vibration aspirator separator is described, which allows to describe the separation process. There was a work hypothesis regarding the separation of seed material. The autoclaving mode of the central tube of the distributor is considered. Investigation of the linear displacement of the central section. The diagram of the forces acting on the seeds is given, namely, the constituents of the coupling force Fv, which creates the vibration of the pipe, the twisting compressive moment, the weight of the seed, the air resistance, the elastic forces.

It is established that using sailing elements at an angle of 450, the separation of seeds into medium and heavy fractions occurs. Sailing elements are located on the pipe in the aspiration channel, the size of which is 10mm. These sailing elements allow you to enhance the air flow, which in turn helps in better separation of seeds. With the help of elastic elements that create self–oscillating movements and turn the pipe with sailing elements at different angles, it helps to process the separation. The elastic elements are mounted from above and below, which in turn allows the pipe to come back and improve the separation process. The proposed design of the separator, together with these elastic elements and sailing elements, increases the air velocity, and make the seed splitting better. It has also been established that the separation process in the vibroaspiration separator is carried out using the pneumodynamic and gravitational forces.
