CORN DIRECTIONAL SEED SOWING DEVICE

摘要

A corn directional seed sowing device, a plough-free directional seed sowing machine and a combined operation machine set. The directional seed sowing device comprises a seed strip box (1), a seed strip feeding mechanism, a seed pushing mechanism, a seed gathering mechanism and a seed sowing mechanism. A seed strip outlet is aligned with a seed gathering slot (4), and the gathered seeds are pushed by a seed sowing mandrel (501) into soil. The plough-free directional wide/narrow row seed sowing machine and the plough-free directional combined operation machine set mounted with the device control growing orientation of leaves by using seed information, thereby implementing staggered deployment, uniform growth, symmetric heads and wide/narrow row spacing cultivation of double-row plants, and creating a group structure having reasonable density plantation and high filtration of growing micro-environment of plants, so as to implement the plough-free sowing in the real sense, and greatly improve the yield of the corn.
