Mini-aggregat for digging potato

Abstract

An important place in the group of mobile power tools for potato harvesting is occupied by motor-blocks and mini-aggregates based on them. The use of such equipment in Ukraine is growing rapidly. Therefore, the actual issues of research are studying and improving the constructions and conditions for the aggregation of such mobile power tools. In the work the analysis of literary sources on the subject of equipment, operation and technical characteristics of aggregates of the specified type is carried out. On the basis of the analysis, the necessity of improving the equipment assembly in the course of its work, improving the technical and economic indicators, improving the maneuverability of the aggregate is disclosed. The article describes the process of operation of the modernized mini-aggregate "motoblock + paw-digger" for harvesting root crops. Presents the results of experimental studies for basic and modernized miniaggregates. Conducting experimental research involves determining the limiting values of traction effort, fuel consumption and maneuverability of the modernized mini-aggregate. The experimental tests were performed on two sites (the first - is no weediness, the second - is weedy), covering an area of 500 m2 . The results of the research proved the ability of the upgraded miniaggregate to dig potatoes on weed soils with performance better than the performance of the basic mini-aggregate.
