The invention relates to a hobbing type lotus seed shucker, which is composed of a frame, a feeding mechanism, a conveying mechanism, a cutting mechanism, an uncoating mechanism, a motor and the like, wherein the conveying mechanism is driven by a grooved pulley, and step performing of lotus seed shucking and uncoating is realized by the intermittent movement of a grooved pulley mechanism, so that the shucking is more thorough and more effective; and spring adjustment systems are respectively installed on the shucking mechanism and the uncoating mechanism, and the springs can automatically adjust the distance between a cutting blade and an uncoating roller as well as a rubbing roller according to the lotus seed size, so that the shucking of lotus seeds with different sizes is adapted. The shucker has the characteristics of high shucking rate and low breakage rate in the shucking process, and has the characteristics of simple structure, small volume, low manufacturing cost, stability in operation and the like in the equipment performance.
