Sažetak
U radu su prikazani rezultati analize eksploatacionih parametara mašine za formiranje mini gredica. Ispitivanje je izvedeno u toku leta 2005. godine kad je mašina agregatirana sa traktorom nominalne snage motora 96 kW i 2006. godine, kad je mašina agregatirana sa traktorom nominalne snage motora 139 kW. Visina formiranih mini gredica iznosila je 18 cm a širina gornjeg dela mini gredice 24 cm, što je dovoljno za setvu dva reda mrkve. U toku 2005. god. ostvarene su niže vrednosti proizvodnog učinka Wpr = 0,198 ha/h, zbog manje vrednosti radne brzine, v = 1,059 km/h. U toku 2006. godine ostvaren je proizvodni učinak od Wpr = 0,343 ha/h, pri čemu je radna brzina iznosila v = 1,91 km/h. Korišćenjem traktora veće snage utrošak ljudskog rada je manji za 42,3%, a utrošak mašinskog rada bio je takođe manji za 16,45%.
Abstract
In this paper resultants of analysis exploitations parameters machines for Mini beds forming are shown. The investigation was carried out during the summer 2005, when the machine for mini beds forming was aggregated with tractor engine nominal power 96 kW, and during 2006 when tractor engine nominal power was 139 kW. The height of mini beds was 18 cm and width was 24 cm. This is enough for two row carrots sowing. During 2005 value field efficiency was low, Wpr = 0,198 ha/h, because of a work speed that was 1,059 km/h. During 2006 value for field efficiency was higher, Wpr = 0,343 ha/h because of work speed that was 1,91 km/h. If tractor with higher power was used, saving of human labor was 42,3%, and the saving of machinery work was 16,45%.
