Mechanization of onion crop lifting is considered of great importance to reduce time, labor and cost that required in the case of hand lifting so, <br/>the main objective of the present work was to develop and manufacture a machine to be suitable for harvesting onion crop. The developed harvester is <br/>a tractor front mounted. The developed onion- harvester consists of frame, lifting device (blade and collected roller), elevator and collecting device. <br/>Experiments were carried out to evaluate the performance of the developed harvester under parameters: four depths of harvest (4- 6- 8 and 10 cm) and <br/>four forward speeds (0.720 - 0.837 - 0.947 and 1.125 km/h) under 22%moisture content of to determine field capacity and efficiency, lifting efficiency, <br/>total crop losses, power and energy consumed, and total cost requirements for harvesting onion crop. The results indicated that, the maximum field <br/>capacity was 0.180 fed/h at speed of 1.125km/h and the maximum field efficiency was 73.9 % at speed of 0.720km/h, it was recorded at depth of 4cm, <br/>compared with manual method which recorded the field capacity and field efficiency were 0.125 fed/h and 84.26%, respectively. The maximum lifting <br/>efficiency and minimum total losses were 99.2% and 1.9% obtained with the use of the developed onion harvester, compared with manual method which <br/>recorded 98.1 % and 2.5%, respectively. The minimum power and energy consumed were 10.112 kW and 59.5 kW.h/fed at depth of 4cm and forward speed <br/>of 0.720km/h obtained under onion harvester, compared with manual method which recorded 0.759 kW and 6.072 kW.h/fed, respectively. The criterion <br/>cost for manual harvesting was 2400 LE/fed. It was recommended to operate the developed harvester for harvesting onion crop at a depth harvesting <br/>of 10 cm and a forward speed of 0.720 km/h where the lowest criterion cost was 674.33 LE/fed, the lowest losses was 1.9%, and the least energy <br/>consumed was 59.5 kW.h / fed .<br/> |
