The application provides an air suction type seed sowing device and relates to the technical field of agricultural machinery. The air suction type seed sowing device comprises a front cover and a rear cover, the front cover and the rear cover are used to form an air suction space, the air suction space is provided with an air suction rotating disc which is installed in a rotating mode and is close to the rear cover, a semicircular stretching rubber film is glued to the inner wall of an air suction hole far from a stretching patch, when the semicircular fixed pieces on both sides are mutually adhered to form the minimum spacing, the semicircular fixed pieces on both sides move away from each other, a rhombus-like air suction gap is formed between the stretching patches which are symmetrically arranged on both sides, the size of the air suction gap between the stretching patches is adjusted through the translational motion of the semicircular fixed pieces, the elastic stretching of the flexible rubber film greatly simplifies the structure, a flush air suction surface can be formed on the air suction rotating disc, which is more conducive to the smooth separation in the subsequent steps, the sowing rate is improved, and the air gap adjustment range is larger, so that the air suction type seed sowing device can adapt to the smooth sowing of soybean seeds with various sizes.
