METHOD FOR DIRECTIONALLY SWAYING AND RESETTING HARROW TEETH OF HARROW EXCAVATOR AND HARROW EXCAVATOR IMPLEMENTING DIRECTIONAL SWAY AND RESET OF HARROW TEETH IN THE METHOD

摘要

A harrow excavator implementing a method for directionally swaying and resetting harrow teeth of a harrow excavator comprises a harrow rotary piece (6), directional sway and reset harrow teeth (7), a harrow supporter (3), a driving mechanism (2), a feeder mechanism (5), and a body (4). The directional sway and reset harrow tooth (7) comprises a torsion spring support piece (9), a tooth handle sway limiting piece (12), a directional sway and reset tooth handle (14), a directional sway and reset tooth point (8), a torsion spring tooth handle shaft (11), a torsion spring (13), and the like. The directional sway and reset tooth handle (14) is provided with a tooth handle rotary hole piece (15), the torsion spring (13) is provided inside the torsion spring shaft support piece (9), one end of the directional sway and reset tooth handle (14) is provided with a tooth point sway limiting piece (10), the tooth handle sway limiting piece (12) and the tooth point sway limiting piece (10) limit each other to prevent the directional sway and re-set tooth point (8) from swaying towards a space other than a limit position of the provided tooth handle sway limiting piece (12), the directional sway and reset harrow teeth (7) continues rotation when a material is clamped.
