High-Speed Efficient and Compact Screw Grain Conveyors in Agriculture

Abstract

Improving the efficiency as well as reliability of reaping threshers results in the enhanced efficiency of cereal harvesting. To make the agroindustrial complex as a whole and agriculture, in particular, more efficient, new advanced technologies are necessary. These technologies are based upon the members of modern machines for soil preparation, seeding, crop tending and all harvesting machinery. However, the implementation of their design program is virtually stagnating due to the lack of funding which restricts the forming and development of market and production relations in the agroindustrial complex in their civilized forms on the basis of the advanced technology and new technique. The article provides the research on the way to improve the efficiency of the screw-type conveyor; this allows building a compact design by means of increasing the number of conveyor rotations. The authors describe a technology of operation of grain conveyors and study their operation mechanism and point to their operation deficiencies consisting, in particular, in the lacking opportunities to transfer grain for long distances along the spatial road or complicates a process flow sheet. In addition, operation at loading directly from the heap requires manual labor or additional equipment.
