Modern wheat combine harvesters in PKB Beograd conditions

Abstract

The goal of the investigation was to analyze parameters and indicators of performance for modern combine harvesters, in PKB Corporation conditions, as a basis to review the possibility for improved performance, productivity and decrease in fuel consumption, per unit of product. Based on investigated values for relevant parameters and indicators of fuel consumption amounting to 13.61 l/ha. i.e. 38.11 l/ha for performance of 2.8 ha/h and average speed of 5.5 km/h were established. The level of combine harvesters utilization was 0.70% with the potential for considerable improvement of this parameter by providing better coordination between the regime and the conditions of work.

Cilj ispitivanja je analiza prametra i pokazatelja rada savremenih žitnih kombajna u uslovima PKB korporacije, na osnovu čega će se sagledati mogućnosti povećanja učinka, produktivnosti rada, i smanjenja utroška goriva po jedinici proizvoda. Na osnovu ispitivanja utvrđene su vrednosti relevantnih parametara i pokazatelja, potrošnje goriva od 13,61 l/ha odnosno 38,11 l/h pri učinku od 2,8 ha/h i prosečnoj brzini kretanja od 5,5 km/h. Stepen iskorišćenja kombajna iznosi 0,70%, s tim da bi se vrednost ovog stepena mogla znatno povećati sa boljom usaglašenosti režima rada i uslova rada.
