Radni učinci strojeva za vađenje korijena mrkve | Working performances of carrot root extraction machines

Croatian. U radu su prikazani rezultati terenskih mjerenja radnih performansi i potrošnje goriva u različitim radnim uvjetima. Korištena su tri tipa strojeva za vađenje mrkve (Dewulf, Europa 2000 i Asa lift) na tri lokacije i dvije vrste mrkve (Maestro F1 i Mello Yello F1). U optimalnim uvjetima tla potrošnja goriva strojeva kretala se u rasponu od 8,4 do 12,5 L / ha, dok je u teškim uvjetima rada za strojeve za vađenje mrkve potrošnja goriva značajno porasla na 65%. Učinkovitost vađenja mrkve u optimalnim uvjetima tla kretala se u prosjeku između 3-4 t / ha. U nepovoljnim uvjetima tla (mokro tlo, blato ili suho tlo) radni efekti padaju do 70%, što ima izravne negativne posljedice na ukupne troškove proizvodnje mrkve.

English. This paper presents results of field measurements of working performance and fuel consumption evaluation in various operating conditions. Three versions of carrot extraction machines (Dewulf, Europa 2000 and Asa lift) at three locations and two varieties of carrots (Maestro F1 and Mello Yello F1) was. In optimum soil conditions, fuel consumption ranged from 8.4 to 12.5 L/ha, while in heavy operation conditions for extraction machines fuel consumption increased significantly for 65%. The performance of carrot extraction in optimal soil conditions was on average between 3-4 t/ha. In unfavorable soil conditions (soil sodden, mud or too dry soil) working effects up to 70% and this has direct negative consequences on the overall carrots production costs.
