The invention provides a direct seeding device, which can improve the control degree of the seeding depth by arranging a hard-soft sensor (114). The invention is characterized in that a direct seedingdevice (82), which is freely arranged at the rear portion of a running car body (12) relative to the running car body by the elevating of an elevating hydraulic cylinder (46) and an elevating connecting lever device (3), has transfer pipes (93, 95) for respectively transferring the seeds to a farmland, floats (55, 56) are arranged at the lower part of the direct seeding device (10), ground-leveling tools (27a, 27b) are freely arranged relative to the elevating of the direct seeding device (82), the ground-leveling tools (27a, 27b) are arranged in front of floats (55, 56) to contact the groundfor levelling the ground, and a soft-hard sensor (114) for detecting the soft-hard degree of the farmland is arranged between the floats (55, 56) and the ground-leveling tools (27a, 27b).
