Claims

[Scope of utility model registration request]

A support cylinder is fixed vertically to a rotating shaft horizontally mounted on the body of the propulsion vehicle, and the base end of a tiller blade is inserted and fixed into the support cylinder, and the tiller blade sequentially moves from the base end to the tip. The base part belongs to a plane perpendicular to the rotation axis and is curved in an arc shape gradually moving away from the axis, and the cutting part is bent from the base part in a spiral shape centered on the rotation axis. At the same time, the tip edge on the cutting edge side of the cutting section is formed to have a rotation radius larger than the rear edge by the distance that the rotating shaft moves forward when rotating the angle of the blade width of the cutting section, and the reversing section Furthermore, the tilling blades are bent further toward the rotation axis, and a plurality of the tilling blades are arranged at intervals on the rotation axis by changing the phase, and the inverted portion of each tilling blade is rotated at the base of the adjacent other tilling blade. A tilling rotor characterized by being visible within the locus.
