Electrical control scheme of the machine for isolation of toxic ergot from rye grain

Abstract

Abstract The grain heap contains, in addition to high-grade grain, various impurities, which include ergot toxic sclerotia. Poisonous ergot sclerotia most often affects rye grains. The duration of flowering and the structural features of its flowers explain the strong susceptibility of rye to ergot. The use of various machines for cleaning grain does not give positive results in the isolation of toxic ergot from rye grain due to the proximity of its properties and the properties of the crop being cleaned. Purification of seeds from ergot sclerotia, having a density lower than the density of rye grain, is possible in an aqueous solution of salt. To mechanize the release of ergot from rye grain by density in an aqueous salt solution, the development of an appropriate device is an urgent issue. When creating a machine for the allocation of toxic ergot, simple in design and maintenance, the question arises of developing an electrical circuit for controlling the working bodies. To drive the working bodies of such a machine, a simple single-phase electrical circuit for controlling a three-phase electric motor has been developed. The developed electrical control circuit made it possible to ensure reliable and trouble-free operation of the electric drive of the working bodies of the machine for the extraction of toxic ergot from rye grain during experimental studies. The installation of the control circuit has an electrically safe design, convenient for operation, and the protection elements of the circuit exclude a person from electric shock and fire.
