Abstract

U uvodu rada objašnjeno je što je to rezidba granja i živih ograda te značaj koji obrezivanje ima u njezi drveća i živih ograda. Nakon uvodnog dijela slijedi analiza tržišta, kojom su prikazani načini i različite vrste uređaja za obrezivanje. Kako je zadatak ovog rada koncipirati i konstruirati traktorski priključak za rezidbu krošnji drveća, voćnjaka i živih ograda, pregledom postojećih proizvoda iz te skupine, generirani su koncepti. Na temelju određenih kriterija, koji predstavljaju najbitnije karakteristike uređaja, provedeno je vrednovanje koncepata te je kao najbolji odabran onaj najveće sume ocjena. Nakon odabira najboljeg koncepta kreće se u detaljnu razradu uređaja u kojoj su odabrani standardni dijelovi i proračunati oni nestandardni. Na temelju provedenog proračuna izrađen je 3D model uređaja i tehnička dokumentacija u programskom paketu SolidWorks. Na kraju je napravljen detaljan prikaz i opis uređaja i njegovog rada.

Abstract (english)

In the introduction is explained what is pruning of branches and hedges. Also, it is explained the importance which circumcision has on caring for trees and hedges. Introduction is followed by market analysis, which shows the methods and different types of pruning devices. The assignment of this thesis was to conceptualise and design tractor attachment for pruning tree tops, orchards and hedges, by reviewing existing products from this group, concepts were generated. Based on the particular criteria, which represent the most important characteristics of the device, concepts were evaluated and the one with the highest sum was selected. Then started a detailed elaboration of the device in which were selected standard parts and computed the ones that were nonstandard. Based on the completed calculation, a 3D model of the device and tehnical documentation were made in SolidWorks software package. Finally, a detailed presentation and description of the device and its operation was made.
