Abstract

Zadatak ovog diplomskog rada bio je koncipirati i konstruirati nošeni traktorski priključak koji služi za košnju i usitnjavanje korova i šikare. Pogon priključka bilo je potrebno izvesti s izlaznog vratila traktora. U provedenoj analizi tržišta prikupljene su informacije o postojećim uređajima na tržištu, načinu njihova priključka na traktor i parametrima traktorskog pogona.

Na temelju istraživanja tržišta krenulo se u fazu koncipiranja te su bila generirana četiri koncepta koji su se vrednovali te je za daljnju razradu odabran najbolje ocijenjeni koncept. Vrednovanje koncepata vršilo se na temelju devet kriterija koji su imali različite težinske faktore. Prema provedenom proračuna izrađen je računalni model uređaja u 3D CAD sustavu te je izrađena tehnička dokumentacija osnovnih sklopova i dijelova uređaja. Rezultat rada je konstruirani uređaj mase 358 kg koji zadovoljava postavljene zahtjeve.

Abstract (english)

The task of this graduate thesis was to develop concepts and to design a Tractor mounted mulcher. Drive of the mulcher had to be done from the tractor's output shaft. Data about existing products on the market, how they connect to tractor and parameters of tractor drive train were collected by conducting a market analyzes.

Conceptual stage, in which four concepts were generated and evaluated, was based on the market research. Best-rated concept was chosen for further elaboration. Evaluation of concepts was based on nine criteria that had different weight factors. From the calculations a computer model of the product was created in the 3D CAD system. Technical documentation of the main assemblies and parts of the product was also created. The result of the carried out work is the machine which weighs 358 kg and meets the set requirements.
