An inclined inwardly-transplanting wide-narrow row transplanting mechanism comprises a power transmission case (1), a left transplanting mechanism (7) and a right transplanting mechanism (3). A left power output shaft (8) and a right power output shaft (6) are assembled on the left side and the right side of the power transmission case (1), the shaft axes of the left power output shaft (8) and the right power output shaft (6) are configured to be inclined downwards and symmetrical with respect to a horizontal plane. A driven bevel gear (4) engaged with a driving bevel gear (2) on a main driving shaft (10) in the power transmission case (1) is assembled on the left or right power output shaft (8, 6). A left bevel gear (9) and a right bevel gear (5) are respectively assembled on the left power output shaft (8) and the right power output shaft (6) and engaged with each other, and the transmission ratio is 1:1. The left transplanting mechanism (7) and the right transplanting mechanism (3) are vertically mounted and meshed with the left and right power output shaft (8, 6). The left transplanting mechanism (7) and the right transplanting mechanism (3) as a whole is the inwardly inclined symmetrical structure which takes a shape of an inverse "八", and the symmetrical structure is wide at the seedling-taking part and is narrow at the seedling-transplanting part. The mechanism can achieve the inward-offset transplanting operation after taking seedling via the left transplanting mechanism and the right transplanting mechanism. The mechanism solves the technical problem of damming mud, damming water and pushing over the seedlings.
