University of Tehran Press Iranian Journal of Biosystem Engineering 2008-4803 48 1 2017 04 21 Design, constructing and evaluating a tractor mounted garlic harvester machine Design, constructing and evaluating a tractor mounted garlic harvester machine 125 119 61567 10.22059/ijbse.2017.61567 FA Hossein Maghsoudi Shahid Bahonar University of Kerman Journal Article 2016 10 02 Harvesting is one of the most difficult and labor-intensive stages of garlic production and needs a lot of money and effort. In this study, to fix this problem mechanized harvesting machine designed, constructed and evaluated. This machine pulls the garlics out of the ground by two V-shaped belts and a blade that carries them to the topping unit and cuts their heads. The power requiring to move the belts and topping unit is acquiring from the carrier wheels. To evaluate this harvesting machine some tests were carried out with considering two parameters: advancement moving speed in three levels (3, 4 and 5 Kmph) and three linear speeds of belts (1.2, 1.4 and 1.6 times of advancement speed) using factorials in a completely random form with different blade angels. The results show that the best performance of the machine happens at a speed of 3 Kmph. Also, the best forward speed of the highest quality heading, speed of 3 Kmph and the belts linear speed of 1.2 times of the speed of advancement.
