Malformed seed separating-out device

The invention discloses a malformed seed separating-out device and belongs to the technical field of agriculture. Raw material seeds are added into a feeding hopper and conveyed to a vibrating feedervia a feeding inlet, the vibrating feeder conveys the raw material seeds to seams of a longitudinal separating roller and a transverse separating roller, an engine drives a rotating shaft, the rotation speed of the transverse separating roller is adjusted through a first speed adjuster, the rotation speed of the longitudinal separating roller is adjusted through a second speed adjuster, the seedsare sorted by rotating the longitudinal separating roller and the transverse separating roller, malformed seeds are carried to a separating channel by the transverse separating roller due to the special shape and are discharged out of a malformed seed outlet, and healthy seeds in a uniform shape are carried to a discharging outlet by the longitudinal separating roller and enter a collecting box via the discharging outlet.
