Preferably, described augers comprises screw axis, helical blade, apex point and is arranged at the coupling at screw axis top, helical blade is arranged on screw axis, helical blade outward edge is provided with powder ridge cutter, the number of degrees of described powder ridge cutter and its dihedral angle formed in the plane of the point of attachment of helical blade are greater than 90 degree, be less than 180 degree, described rotating shaft and described coupling are fixedly connected.Powder ridge machinery in the process of walking, because the number of degrees of powder ridge cutter and its dihedral angle formed in the plane of the point of attachment of helical blade are greater than 90 degree, be less than 180 degree, be conducive to abundant the contact with soil of powder ridge drill bit to carry out cutting and stirring, add the cutting power of drill bit and the soil crushing effect of powder ridge machinery, make powder ridge machinery can meet the needs of agricultural production further.
Preferably, described rotating ring, stationary ring all adopt high hardness wear-resisting material, even if when device inside enters impurity, rotating ring and stationary ring also can not produce wearing and tearing because of the intervention of impurity, thus have very long working life.
Preferably, described bearing support is provided with the oil nozzle to inside cavity filling lubricant medium, is convenient to supplement filling lubricant medium to seal arrangement inside cavity in time, prevents because causing dry grinding because lubricant medium runs off after operate longer.
Preferably, described bearing lubrication adopts lubricating grease.Lubricating grease had both had good lubrication effect, was also convenient to maintain good sealing in the labyrinth gap between ring, stationary ring.
Preferably, the internal diameter of described rotating ring and the external diameter of rotating shaft closely supporting, rotating ring by frictional force clamping be fixed in rotating shaft.This means of fixation, structure is simple, easily manufactured, is convenient to manufacture and design.
As the first improved procedure of the present utility model, the labyrinth gap that described rotating ring and stationary ring complement each other to form is staircase curve vertically.This sealing means mounting or dismounting are convenient, and bearing cap must subdivision.
As the second improved procedure of the present utility model, the labyrinth gap that described rotating ring and stationary ring complement each other to form is concavo-convex curve radially.Equally, this sealing means mounting or dismounting are convenient, and bearing cap must subdivision.
As the third improved procedure of the present utility model, the labyrinth gap that described rotating ring and stationary ring complement each other to form is " N " shape curve vertically.This sealing means can do certain swing around bearing centre, is applicable to axle and swings larger place, as selfaligning bearing supporting.
As the 4th kind of improved procedure of the present utility model, the labyrinth gap that described rotating ring and stationary ring complement each other to form is concavo-convex curve vertically.This sealing means takes up room little, and cost is low, is applicable to batch production, and the concavo-convex curve arranged is more, and sealing effect is better.
In sum, by the utility model mazy type bearing obturator, during axis of rotation, because rotating ring is fastened in rotating shaft, bearing is positioned at the inside cavity that bearing support and bearing cap form, and has lubricant medium lubrication, does not have relative movement, good reliability; Relative movement is not had, good reliability between stationary ring and bearing cap, the several part of bearing support; Have the rotating ring of relative movement and stationary ring all to adopt high hardness wear-resisting material, form labyrinth gap between the two, quality of fit is high, and outside foreign material are difficult to enter Bearing inner, thus has good sealing and permanent working life.
