Research of the process of moving cut haulm by a screw conveyor
Main Article Content
Abstract
The technological process of harvesting the tops of large root crops (sugar and fodder beets, chicory roots) is mainly regulated by the agrotechnical properties of the crop, the design of working bodies and layout schemes of the tops-harvesting modules of modern self-propelled root harvesting machines. At the same time, the cut tops are laid in a swath on the harvested field by the screw conveyor of the tops-harvesting module, and the roots, when implementing the flow technology of harvesting, are loaded into a technological transport that moves alongside the root harvesting machine. Purpose of the work: optimization of the parameters of the process of moving the tops by the screw conveyor to the harvested field based on the study of the functional change in the width of the formed tops-winder. The article presents a mathematical model that describes the technological process of moving the cut tops from the screw conveyor coil to the surface of the harvested field and regulates the functional change in the flight range and width of the formed swath of cut tops depending on the yield of the tops, the parameters of the screw conveyor and the speed of the root harvester.
