TRACTOR PULLING NURSERY BED-LEVELING ROTOR

摘要

PROBLEM TO BE SOLVED: To provide a rotor capable of continuously and uniformly leveling a nursery bed while pushing down a floating material into the soil by the cooperation of rotary tines with pressing wheels concentrically rotating with the rotary tines while being pulled by a tractor. SOLUTION: This tractor pulling nursery bed-leveling rotor has transmission cases 7 suspended on an outer terminal part of a horizontal main driving shaft 6 driven by a driving part 2 connected to a power-output port 1 of a tractor, and pivotally supported so as to be rotated on the upper part between right and left supporting side plates 9 arranged so as to face to each other. A transmission system 8a for making a rotation shaft 10 having rotary tines 11 mounted like a spiral, at the lower part between the supporting side plates 9 to carry out the followed movement is installed in one of the transmission cases 7, and a transmission system 8b for making pressing frame wheels 13 concentrically rotating at the outside of the rotary shaft 10 to carry out the followed movement is installed in the transmission cases 7.
