【Abstract】 A new type of machine was designed that would be used to pick up the liquorice. This machine with simple structure would play an important role in the practice. Basic structure of the machine was introduced, the parameters of the key components were analyzed and optimized through experiment. In order to ensure working performance of the digger working, the depth of digging was adopted for 400 mm and the angle of getting into the soil was set for 8°.The damage to the liquorices was limited under 6%, through the traction experiment of the tractor, the power consumption of the work team was calculated, according to which rational power was provided. Further more, shortcoming of the plow that was used at the present time was pointed out by comparing the plow with the liquorice digger.更多还原
