Abstract:Pri traktorjih starejšega tipa je zaradi zasnove pogona priključne gredi onemogočen vzvratni delovni hod, saj se takrat priključna gred vrti v nasprotno smer. Izdelali smo nov pogon obračalnika preko hidromotorja. Ob tem smo morali na traktorju razširiti hidravlični sistem. Predstavili smo osnove hidravlike na kmetijskih strojih, hidravlične črpalke in hidravlični sistem traktorjev. Opisali smo obračalnike in zgrabljalnike za spravilo krme. Zasnovo novega pogona smo naredili z računalniškim modelom v programskem okolju Catia V5R17, izrisali delavniške in sestavno risbo novega pogona, ki so dodani v prilogah. Pogon smo tudi izdelali, opisali njegovo izdelavo in potrebni material ter ga preizkusili v praksi. Uporabili smo zobniški hidromotor. Izkazalo se je, da pogon deluje dobro, rešili smo problem vzvratnega hoda, tako se lahko prihrani čas in gorivo, nevarno obračanje na strmih terenih pa ni več potrebno. Dosegli smo zadovoljive delovne obrate stroja, tako da je površina ob delovnem hodu lepo očiščena. Hidravlično olje se ne pregreva. Z novim pogonom je tudi varovanje ob preobremenitvi veliko bolj učinkovito. Ugotovili smo, da bi se podoben pogon lahko uporabil na več kmetijskih strojih in tako poenostavil njihovo uporabo.

Title:Hydraulic transmission of belt rakes
Abstract:With older types of tractors, a reverse working action is not possible due to the PTO drive design since, at that point, the PTO rotates in the opposite direction. We have made a new tedder drive which is driven by a hydraulic motor. For this purpose, the hydraulic system of the tractor had to be widened. This thesis presents the basics of hydraulics in agricultural machinery, hydraulic pumps, and the hydraulic system of tractors. Tedders and rakes for forage harvesting have been described. The concept of the new drive has been modelled using Catia V5R17 software, and the construction and installation designs of the new drive have been drawn, which are all included in the appendices. The drive itself has also been manufactured, its construction and the materials used for it described, and tested in practice. A hydraulic gear motor was used. It has been proven that the drive functions well, the problem of reverse action has been solved, making it possible to save time and fuel, and the dangerous process of turning on steep slopes is no longer necessary. We achieved satisfactory working machine revolutions which resulted in the surface being nicely cleaned. The hydraulic oil does not overheat. With this new drive the overload protection is also significantly more efficient. We have found that a similar drive could be used for several different agricultural machines and thus simplify its use.
