FIG. 2 is a front view of the soil cleaning head and the soil cleaning mechanism of the present invention;
FIG. 3 is a top view of FIG. 2;
fig. 4 is the utility model discloses dig the use state diagram of rig drill bit clear soil head soon.
Detailed Description
As shown in fig. 1, the utility model discloses dig clear soil head of rig drill bit soon, including wire rope 2, crimping steel bushing 1, crimping steel bushing two 3, the hole of crimping steel bushing 1 includes the taper hole and rather than the cylinder hole of being connected, the hole of crimping steel bushing two 3 is the cylinder hole, wall and wire rope 2 in close contact with of one end and the crimping steel bushing 1 hole at wire rope 2 are fixed to crimping steel bushing 1 suit, the wall and the wire rope 2 in close contact with of the other end and the crimping steel bushing two 3 holes at wire rope 2 are fixed to crimping steel bushing two 3 suit, the right-hand member face of crimping steel bushing two 3 flushes with wire rope's terminal surface, set up a plurality ofly on the crimping steel bushing two 3 and be used for the hole 31 with clear soil mechanism supporting connection.
Wherein the steel wire rope 2 adopts a steel wire rope with the diameter of 30mm-50mm, and the length of the steel wire rope 2 is 300mm-600mm. The steel cord 2 is a steel core steel cord having a strength of 1770mpa to 1960 mpa.
As shown in figures 2-4, the utility model discloses dig the clear head of rig drill bit soon when using, utilize hole 31 on screw 4 and the crimping steel bushing two 3 to be connected a plurality of clear heads and clear soil mechanism 1' for the soil between helical blade 21' of rig drill bit 2' is dug in the clearance soon.
The utility model discloses dig the clear head of rig drill bit soon, adopt this kind of flexible construction of wire rope, strengthened the toughness of clear head of soil, be difficult to appear crooked cracked condition even, prolonged the life of clear head of soil, reduced the time of changing crooked or cracked clear head of soil, improved clear soil efficiency.
