Abstract

Porast trendova zdrave prehrane zadnjih godina uzrokovao je porast potražnje za zdravim namirnicama, a bundeva je jedna od kultura za koju je posljedično poraslo zanimanje. Meso bundeve je niskokalorično i popularno je u pripremi juha, variva, sokova i slično, no zbog visoke nutritivne vrijednosti najveća je potražnja za bundevinim sjemenkama i ulju bundevinih sjemenki. Berba bundeva i ručno izdvajanje sjemenki iz bundeve je mukotrpan i dugotrajan posao pa je stoga poljoprivrednicima vrlo značajno imati stroj koji će brati bundeve i odvajati sjemenke umjesto njih. Kako bi se poljoprivrednicima olakšala i ubrzala berba bundevi i postupak odvajanja sjemenki iz bundeva, u ovom je diplomskom radu konstruiran automatizirani traktorski priključak za branje bundeva i odvajanje sjemenki. U radu su analizirani uređaji dostupni na tržištu namijenjeni za potrebnu djelatnost, definirana je ciljana grupa korisnika kojima će novo razvijeni uređaj biti namijenjen, a na temelju toga definirani su ciljevi razvoja. Potom su napravljene funkcijska dekompozicija i morfološka matrica i generirani su koncepti. Usporedbom koncepata odabran je koncept koji je detaljno razrađen, a na kraju je napravljen računalni 3D CAD model uređaja i napravljena je tehnička dokumentacija.

Abstract (english)

The rise of healthy eating trends in the last years has caused an increase in demand for healthy foods and pumpkin is one of the crops for which interest has grown. The pulp is low in calories and is used for preparation of soups, stews, juices, etc. But, due to high nutritional value the greatest demand is for pumpkin seeds and pumpkin oil. Manually pumpkin harvesting and extracting seeds from a pumpkin is a painstaking and time-consumpting job so it is useful for farmers to have a device that will harvest pumpkins and separate seeds instead. In order to facilitate and speed up the process of separating seeds from pumpkins, in this masters thesis an automated tractor-powered device for pumpkin harvesting and seed extraction has been developed. In the first part, devices available on the market were analyzed, the target group of users for whom the newly developed device will be intended is defined, and based on that development goals were defined. Later, for the newly developed device, functional defomposition and morphological matrix were made and concepts were generated. By comparing the concepts, one concept was selected and that one was elaborated in detail. Finally, a 3D CAD model of the device and technical documentation were made.
