Abstract
U radu su prikazani rezultati simulacije sjetve podtlačnom pneumatskom sijačicom postavljene na ispitni stol u Zavodu za poljoprivrednu tehniku i obnovljive izvore Fakulteta agrobiotehničkih znanosti u Osijeku. Prilikom korištenja sjetvene ploče n=12 i brzine od 4 km/h ostvaren je prosječni razmak 21,89 cm što predstavlja dobiveni razmak manji za 0,95 % u odnosu na teoretski razmak, a upotrebom sjetvene ploče od n=44 otvora zabilježen je prosječni razmak 21,79 koji je manji za 1,41 %. Korištenjem sjetvene ploče n=12 pri brzini od 6 km/h ostvaren je prosječni razmak 23,26 cm što predstavlja dobiveni razmak veći za 4,98 % u odnosu na teoretski razmak, a upotrebom sjetvene ploče od n=44 otvora zabilježen je prosječni razmak 22,55 cm koji je veći za 1,99 %. Korištenjem sjetvene ploče n=12 pri brzini od 8 km/h ostvaren je prosječni razmak 23,14 cm što predstavlja dobiveni razmak veći za 4,49 % u odnosu na teoretski razmak, a upotrebom sjetvene ploče od n=44 otvora zabilježen je prosječni razmak 22,38 cm koji je veći za 1,25 %. Korištenjem sjetvene ploče n=12 pri brzini od 10 km/h ostvaren je prosječni razmak 23,87 cm što predstavlja dobiveni razmak veći za 7,42 % u odnosu na teoretski razmak, a upotrebom sjetvene ploče od n=44 otvora zabilježen je prosječni razmak 22,52 cm koji veći za 1,86 %.
Abstract (english)
The paper presents the results of a simulation of seed sowing using a vacuum pneumatic seeder placed on a test bench at the Department of Agricultural Technology and Renewable Resources at the Faculty of Agrobiotechnical Sciences in Osijek. When using a seeding plate with n=12 holes and a speed of 4 km/h, an average spacing of 21.89 cm was achieved, which represents a spacing that is 0.95% smaller compared to the theoretical spacing. Using a seeding plate with n=44 holes resulted in an average spacing of 21.79 cm, which is 1.41% smaller. When using a seeding plate with n=12 holes at a speed of 6 km/h, an average spacing of 23.26 cm was achieved, representing an increase of 4.98% compared to the theoretical spacing. Using a seeding plate with n=44 holes resulted in an average spacing of 22.55 cm, which is 1.99% larger. Using a seeding plate with n=12 holes at a speed of 8 km/h resulted in an average spacing of 23.14 cm, representing an increase of 4.49% compared to the theoretical spacing. When using a seeding plate with n=44 holes, an average spacing of 22.38 cm was recorded, which is 1.25% larger. Finally, when using a seeding plate with n=12 holes at a speed of 10 km/h, an average spacing of 23.87 cm was achieved, representing an increase of 7.42% compared to the theoretical spacing. Using a seeding plate with n=44 holes, an average spacing of 22.52 cm was recorded, which is 1.86% larger.
