The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug.
Rotary drilling rig drives the shaft to rotate and exert positive pressure so that the rotary dril- ing bit can impact, roll and shear the rock. Crush the rock to form a crushing ring zone.Then break the middle pillar by the swing of the shaft and take the broken pillar out to form a hole.
HPR35 Mini rotary drilling rig offers low clearance and lightweight construction as its core advantages, making it ideal for confined working environments and complex site access requirements.
Spherical hobs are very mature and are widely used in many equipment, such as rotary drilling rigs, RCD, pipe jacking machines, etc. By analyzing the use of ball-tooth hobs on the above equipment, it can be known that when there is sufficient propulsion pressure and the rock layer strength is about 130MPa, the footage speed of the spherical tooth hob can be maintained at 0.3~0.5m/ h. And the footage speed is relatively stable. When the spoil discharge is sufficient, the service life of one spherical tooth hob can reach a construction length of 300m.
