Abstract

The utility model discloses a minitype rice transplanter used for transplanting seedlings in paddy fields, which comprises a controller for a seedling disk, a seedling transplanter and a seedling driving mechanism. The utility model is characterized in that the vertical movement of a control lever is changed into the rotation of a main shaft, and the seedling transplanter is driven to rotate. A fork for transplanting seedlings at the front end of the seedling transplanter completes the actions of taking seedlings on an upper row and transplanting seedlings at a lower row along an elliptical orbit under the match of a rocker arm, and simultaneously, the rotation of the main shaft drives a bottom frame of a seedling disk to transversely move by a commutator to be convenient for the fork for transplanting seedlings to take seedlings. The utility model has the advantages of small size, flexible movement and high seedling transplanting efficiency, and can be operated by one man.

Description
