ANALYSIS OF THROUGHPUT RATE OF HARVESTING AND TRANSPORTATION COMPLEX OF MACHINES FOR SUGAR BEET PRODUCTION

Abstract

The article presents a methodology for analyzing the capacity of the harvesting and transport complex (HTC) for sugar beet, which is aimed at finding ways to rationally use the resource of machines in the technological complex. The reloading method of transportation of beet crop is considered, the feature of which is flexibility, adaptability to weather and climatic and economic conditions during harvesting. Under favorable weather conditions and the availability of a sufficient number of motor vehicles (MV), beets, which are taken from the combine harvester from the field by tractor semi-trailer (TS), are reloaded into heavy-duty MV, which are located on the road from the edge of the field, and transported to the sugar factory. In case of changes in conditions (in rainy weather, with overmoistened soil or with insufficient number of vehicles), a loader-cleaner is added to the complex of machines and the work of the complex switches to a transshipment or flow transshipment method. Harvesting and transportation of beets is considered as the work of the technological chain, which consists of three links: "field - beet harvester (BH)", "BH - NP", "NP - ATZ". The main steps of the throughput analysis are determination of the throughput of the first, second and third links, their comparison and subsequent selection and analysis of alternatives that allow to overcome the possible significant difference between their values. The possibility of reducing the throughput of the third link to the maximum possible - the throughput of the first link by reducing by a certain number of vehicles for the transportation of beets with a simultaneous increase in their technical speed. The given example of calculating the number of units of equipment in the harvesting and transport complex in accordance with the developed methodology proves its effectiveness and advantages. The analysis of the throughput capacity of the ZTC shows ways to improve the parameters of the transport process in the technological complex of harvesting and transport operations.
