Modernization of technical means for separation of grain-grain graff

Abstract

The successful functioning of agricultural production at the present stage of development presupposes the creation of agro-engineering systems operating on innovative principles. In this set of tasks, the technical support of cereal production has a key place. Post-harvest treatment of grain is of paramount importance, including its pre-purification, namely, separation of grain straw heap. Therefore, the solution of the technical task of modernizing the technical means for separation of grain straw heap is a pressing problem. A wide overview of literary sources devoted to this topic, a comprehensive and thoughtful analysis of inventions made it possible to modernize device at the level of patentability. Proposed modernization of apparatus is achieved due to uniform feed, which provides thin-layer stratification with required orientation of particles moved by conical spreader into formed annular air flow. A distinctive feature of the proposed device is a new form of execution of known structural components, namely, the representation of the feeder in the form of a funnel-shaped hopper with an outlet slot, as well as a ring-shaped dispenser, the design of a conical spreader equipped with straight blades, including receiving chambers made in the form of a design of circular funnel-shaped working chambers. In addition, a characteristic feature of the proposed apparatus is the presence of a device for directing the air flow in the form of a cone. The hopper of a funnel-shaped design with an outlet slot allows to stabilize the movement of the components of the processed material before they arrive at the ring dispenser. Availability of design features of the proposed apparatus ensures realization of technical result at the level of patentability, which provides an increase of productivity, as well as efficiency of extraction of output components from processed material.
