Inclined interpolation wide and narrow row spacing rice seedling transplanting mechanism belongs to agricultural machinery. A left power output shaft and a right power output shaft are correspondingly assembled on the left side part and right side part of the power transmission case, wherein the axes of the left power shaft and the right power output shaft are symmetrically arranged and incline downwards relative to the horizontal plane, and wherein the left transplanting mechanism and the right transplanting mechanism are perpendicularly attached to the left power output shaft and the right power output shaft respectively to form a V-shaped symmetrical structure with constant seedling taking space and narrow rice seedling transplanting space in the whole. A driven bevel gear is attached to the right power output shaft or the left power output shaft. A driving bevel gear on a main driving shaft in the power transmission case meshes with the driven bevel gear. A left bevel gear and a right bevel gear are respectively attached to the left power output shaft and the right power output shaft and the left bevel gear meshes with the right bevel gear mesh, wherein the transmission ratio is 1:1. It is realized in the invention that the left and right transplanting mechanisms both offset inward to plant the seedlings after they fetched the seedlings. It has simple structure and small space occupation, which makes the inward inclined narrow row transplanting possible. It needs low cost and easy installation. The row spacing is increased by 10 cm compared with the transplanted line. Therefore the connect seedling line has less possibility of hilling mud and dammed water and the seedlings avoid being pushed down. The invention is particularly suitable for general riding-type transplanters with high speed operation and integrated floating boards.
