| Abstract | ||||
| The digging harvesting machine was modified and tested to perform the effect of harvesting speeds on harvesting carrot as lifting, un-lifting, damaged, un-damaged and machine productivity. These indicators were evaluated under condition of medium at El Dakahlia Governorate in Belqas, Egyptian. A lot of the experimental field were conducted on carrot harvesting under three different levels of separator length (450, 700 and 1200mm); reciprocated cam with link length of 180, 210 and 240 mm and three forward speeds (3.6;, 5.1 and 7.2km/h) and three share (Sweeping, Nose and Shovel). The obtained results concluded that the maximum value of carrot lifting efficiency was 99% recorded at nose shape type, 3.6 km/h harvesting speed, separator length 1200mm and reciprocated cam with link length of 210mm. At reciprocated cam with link length of 180mm, increasing forward speed from 3.6 to 7.2 km/h increased the un-lifted of 6, 7 and 9% times at separator length of 450, 700 and 1200mm respectively. Generally, increasing harvesting speed increased carrot damage. For example, recorder less value to damage 1.99at forward speed3.6km/h, sweeping shape type, reciprocated cam with link length of 180mm and length separator 450mm. while recorded highest value to mechanical damage 10% at forward speed 7.2km/h. By increasing forward speed from 3.6 to 7.2 km/h decreased productivity under all treatments at reciprocated cam with link length of 180, 210 and 240mm. | ||||
