The invention discloses an air-passage rice transplanter and belongs to the technical field of agricultural field of agricultural transplanter. The air-passage rice transplanter comprises a transplanter body, an engine assembly, a gearbox and the like. A vertical moving tube may be moved up and down in a vertical fixed tube through rotation of a first gear; a transverse moving tube can be moved side to side on a transverse fixed tube through rotation of second gears; stirring arms can be moved up and down, and side to side; when the stirring arms are moved rightward, seedlings with soil closeto seedling conveying pipes are pushed into the seedling conveying pipes; when the stirring arms are moved up, leftward and down, the seedlings with soil close to the seedling conveying pipes are pushed again into the seedling conveying pipes; the seedlings with soil are conveyed by such cycle; a fan can operate such that wind is delivered into the seedling conveying pipes via an air pipe, the seedlings with oil in the seedling conveying pipes are transplanted in a ricefield. Both the seedling conveying mode and the seedling transplanting mode herein have no chances to damage seedlings.
