According to the agricultural demands of leeks harvest, we did the shearing test of leek’s rootstock and the compression test of leek’s stem leaf, and built the shear mechanics model. On that basis, we studied the leeks harvest cutting table, and designed the critical component, such as cutting knife, conveyor belt and so on, which applied to leeks mechanization harvest. The cutting knife is installed on the cutting knife rack. The conveyor belt is braced by two groups belt rollers which are appearing 90°to each other. The cutting knife and the conveyor belt are drove by hydraulic motor. Combine the results of leeks mechanics tests, we confirmed the parameters in theory, such as rotate speed of cutting knife, installation angle of conveyor belt, relative velocity of conveyor belt and so on, which lays a foundation for the mechanization of leeks harvest.
