PROCESSES OF SCREW CONVEYOR OPERATION IN GRAIN MATERIAL HANDLING

Post-harvest processing of cereal crop yields to achieve the required quality standards involves a number of transport operations for moving grain during drying, cleaning from impurities, grading, seed dressing, and other related processes. At grain handling sites of small multi-sectoral farms, where only a limited volume of such operations is required, the most efficient solution is the use of compact, low-maintenance screw conveyors. Objective of the study: to analyse the existing processes and designs of transport mechanisms for moving grain materials and to propose an improved design scheme for a mobile compact screw conveyor. One of the most efficient methods of conveying bulk materials, including grain products, is by means of a helical screw installed within a guiding casing. Screw conveyors are employed for delivering grain to the required destination as part of such a technological process. We have proposed an improved design of a compact screw conveyor intended for loading and unloading operations at grain handling sites of small multi-sectoral farming enterprises. The main components of the pneumatic-screw conveyor are the frame, which carries the electric motor and the screw conveyor assembly. The screw conveyor consists of a guiding cylindrical tube with a helical screw mounted inside it, and a feed hopper positioned on the upper side of the guiding tube. A safety clutch and a drive pulley for rotating the screw are installed on the input shaft of the auger; rotation is provided by the electric motor. A methodology for implementing experimental research to determine the main technological indicators of the screw conveyor operation process is proposed. The research results obtained serve as the initial data for further justification of the optimal parameters of the working components of the screw conveyor at the stage of technical design.
