Method for manufacturing film-removing tooth of land-arc-imitated mechanism

The invention relates to a method for manufacturing a film-removing tooth of a land-arc-imitated mechanism. The upper and lower portions of the left end of the film-removing tooth are provided with afirst bearing, a second bearing, a third bearing, a lower fixing shaft (25), an upper fixing shaft (26) and a fourth bearing respectively; the lower fixing shaft (25) is welded to the upper fixing shaft (26) through a second reinforcing rod and a sixth reinforcing rod; the first bearing, the second bearing, the third bearing and the fourth bearing are installed at the two ends of the lower fixingshaft (25) and the two ends of the upper fixing shaft (26) respectively and slide vertically through a U-shaped sliding groove (28), and a rectangular block fixing groove (9) is fixed on a partial rack through nuts. During the operation of the method for manufacturing the film-removing tooth of the land-arc-imitated mechanism, different land imitation functions can be achieved along with differentterrains after crops are h
