STRUCTURAL ANALYSIS AND DEVELOPMENT TRENDS OF DRAG CHAIN CONVEYORS USED IN THE AGRO-INDUSTRIAL SECTOR

Abstract

The article investigates the current state, design features, and development trends of drag chain conveyors widely used in the agro-industrial sector of Ukraine for the transportation of grain, compound feed, oilseed processing products, and other bulk materials. The relevance of improving conveying and technological equipment is substantiated by the significant role of the agricultural sector in the national economy and the growing requirements for the efficiency of logistics processes. A review of scientific publications devoted to the energy efficiency, reliability, operating dynamics, and structural optimization of drag chain conveyors has been carried out.

An overview of the Ukrainian drag chain conveyor market is presented, including an assessment of the ratio between domestic and imported manufacturers and the identification of the main directions of industry development. The design of the main conveyor components, including conveyor casings, drive stations, tensioning stations, and various types of traction chains, is analyzed. Plate chains, welded steel chains, and fork chains are characterized with consideration of their operational advantages and disadvantages. The influence of design solutions and construction materials on the reliability, durability, energy efficiency, and manufacturability of the equipment is examined. Particular attention is paid to the use of modern lining materials for extending conveyor service life under conditions of intensive abrasive wear.

The research findings may be applied in the design, modernization, and selection of drag chain conveyors for agro-industrial enterprises.
