PROBLEM TO BE SOLVED: To improve the dust collector of a hulling sorter. SOLUTION: In a shaking type hulling sorter consisting of the grain box 38 housing lifted grain of a grain lifter 5, a dust collecting air duct 43 for sucking and removing dust from the lifted grain in the grain box 38, a grain lifting part dust collecting air duct 44 for feeding the dust removed into the dust collecting air duct 43 to the suction fan 13 of a hulled winnowing part 2, a shaking part dust collecting air duct 48 and a winnowing part dust collecting air duct 49, an air duct plate having a recessed cross section and long before and behind is joined to the inner surface of the right-hand plate 28b of a shaking box 28, which is loaded with shaking sorting plates 15, 15..., in a forwardly inclined state to constitute the shaking part dust collecting air duct 48 and the lower ends of front and rear shaking arms 31, 31 supporting the shaking sorting plates 15, 15... are supported in the vicinity of the upper side of the shaking part dust collecting air duct 48 of the shaking box 28. The shaking support state of the shaking sorting plates 15, 15... becomes strong and the constitutent members of the shaking part dust collecting air duct 48 are reduced to achieve cost reduction.
