Abstract: In order to solve the problem of high labor intensity and low efficiency in artificial harvest of xinjiang jujube, a self-propelled air suction jujube pickup machine was designed to realize the functions of picking up and removing miscellaneous matters on the ground jujube.To obtain the suspension characteristics of jujube and its leaves, the suspension rate of red jujube is 12.45 m/s to 23.69 m/s and the suspension rate of jujube leaves does not exceed 3 m/s. By using the dynamic pressure loss of the inlet and outlet of the air suction, the necessary wind speed conditions of the inlet of the air suction are calculated. The design and function of impurity guide roller are introduced.The size of the air inlet and jujube chamber of the settling chamber was calculated and determined. Field test results show that when the fan rotation speed is 2900 r/min, the harvest rate is ≥98.3%, the damage rate is ≤3.83%, and the impurity rate is ≤3.02%.
