The invention belongs to the field of agricultural machinery, and in particular, relates to a crawler unit of a single-wheel rice transplanter. A traditional single-wheel rice transplanter walking device mostly adopts wheel type drive; a driving wheel is small in contact area, so that the phenomenon of bogging and slip is liable to be generated in the operation in a rice field with deeper mud water, and seriously, the overturning of the whole machine is caused by incapability of keeping the balance of a car body. In order to overcome the defects, the crawler unit is provided; the unit comprises a rubber track, a driving wheel, a support wheel, a bracket, a tensioning wheel and a tensioning screw rod; the driving wheel is connected with a transmission output shaft of the rice transplanter, and is connected with the bracket through a shaft sleeve; the support wheel and the expansion wheel are fixed on the bracket; the support wheel is in a middle position of the bracket; and the tensioning wheel is at the front end of the bracket. The unit has such advantages as large contact area, smooth walking, slip prevention and bogging prevention. Meanwhile, the unit is simple in structure, reliable in operation and convenient for operation and maintenance.
