Abstract (Croatian)
U radu je osmišljena i konstrukcijski razrađena rotaciona kosilica s mogućnošću sakupljanja trave. Rotaciona kosilica služi za održavanje travnatih površina, a prvenstveno je namijenjena za spajanje s malim poljoprivrednim traktorima. Prihvat radnog priključka izveden je preko standardne tro-spojne veze, a snaga se dovodi preko kardanskog vratila. Prijenos snage dalje se izvodi preko remenskog prijenosa na bubnj s noževima. Analizom postojećih priključaka odabrani su standardni dijelovi, a cjelokupni 3D model napravljen je u programskom paketu SolidWorks. U prvom dijelu rada napravljena je analiza tržišta, funkcijska dekompozicija te izrada koncepta. Naglasak je stavljen na smanjenje mase priključka te jednostavnost održavanja. Drugi dio obuhvaća odabir i proračun ključnih dijelova radnog priključka nakon čega slijedi zaključak.
Abstract
In this bachelor thesis it is designed and developed a rotary mower with grass-collecting capability. The implement is used for the maintenance of grassland, and is primarily designed to be attached on a small agricultural tractors. It is attached to a tractor via standard three-point hitch, and power is supplied through the PTO. Further power transmission is done through power transmission belt and drum with blades. By analyzing the existing ports, standard parts were selected and a complete 3D model was made with SolidWorks software. In the first part of the paper is made an analysis of the market, a functional decomposition and is developed a project. Emphasis is placed on the weight reduction of the implement and its easy maintenance. The second part of the paper includes the selection and the calculation of the key parts of the implement and is followed by conclusion.
