Small-plot external traction type corn planter

The invention provides a small-plot external traction type corn planter, and relates to the technical field of agricultural planting tools. The small-plot external traction type corn planter consistsof a planter body, traction machines and traction guide tracks, wherein the traction guide tracks are arranged at two ends of a small plot in parallel; the traction machines are slidably mounted on the traction guide tracks; an electric capstan is mounted at the upper end of each traction machine; stranded wires of the two electric capstans are separately connected with hanging buckles mounted attwo ends of the planter body in a buckled manner; and the traction machines at the two ends and the planter body are aligned and arranged in the longitudinal direction. Integration of ditching, seeding, earthing and compaction for corn farming of the small plot can be realized. Accurate, variable-quantity and efficient seed sowing can be realized. A furrow opener can reverse in two ways, and doesnot need to turn round, but
