20.500.12556/DKUM-42362 Vpliv ekonomske priključne gredi na porabo goriva pri delu z vrtavkasto brano Effect of the economy PTO shaft on the fuel consumption working with power harrow Zorana zemlja ni dovolj zdrobljena in poravnana, da bi bila primerna za setev, zato jo moramo dopolnilno obdelati. Uporaba vrtavkaste brane je najbolj razširjena metoda za dopolnilno obdelavo tal. Namen diplomske naloge je ugotoviti, kako obdelati določeno površino, da bomo za to porabili čim manj goriva in časa. Zanimalo nas je, kako na porabo goriva vpliva število vrtljajev motorja in priključne gredi. Primerjali smo porabo goriva pri dopolnilni obdelavi tal na jeseni in na spomladi zoranih njivah. Za poskus smo uporabili traktor Case-IH JX90 in vrtavkasto brano VOGEL NOOT Terramat L 250. Povprečna poraba pri brananju na jeseni zorani njivi pri nazivnih vrtljajih motorja 2199 min-1 je znašala 10,7 l/ha, pri vrtljajih motorja 1715 min-1 pa 7,9 l/ha. Na spomladi zorani njivi je znašala poraba pri 2199 min-1 9,5 l/ha, pri 1715 min-1 pa 8,7 l/ha. V obeh primerih je bila hitrost vrtenja priključne gredi 540 min-1. Z gotovostjo lahko trdimo, da je uporaba ekonomske priključne gredi smiselna in ekonomsko upravičena. Plough soil is not enough crushed and levelled to be appropriate for sowing, so it needs to be complementary cultivated. The use of power harrow is the most common method for ground complementary cultivation. The main purpose of thesis was to find out, how to cultivate certain farmland with the lowest fuel and time consumption. We were interested in the effect of the number of revolutions on the fuel consumption and PTO. We compared the fuel consumption in ground complementary cultivation of autumn and spring plough field. We used tractor Case-IH JX90 and power harrow VOGEL NOOT Terramat L 250 for our experiment. Average trailing implement consumption of autumn plough field was 10.7 l/ha by 2199 min-1 rated number of revolutions and 7.9 l/ha by 1715 min-1. Average consumption of spring plough field added up to 9.5 l/ha by 2199 min-1 and 8.7 l/ha by 1715 min-1. In both examples the rotation speed of power harrow was 540 min-1. We can definitely assert that the consumption of economy PTO is reasonable and economically justifiable.
