Abstract
Provided is a stone-crushing drill bit, comprising a submersible gravel pump at the upper portion. The upper end of the submersible gravel pump is connected with a drilling rod, and the lower portion is equipped with a left slurry-suction steel pipe and a right slurry-suction steel pipe. The lower end of each slurry-suction steel pipe is provided with a suction port. The upper end of a slurry outlet pipe of the submersible gravel pump is connected with the drilling rod. The lower end of the submersible gravel pump is connected with a submersible motor, the lower end of which is connected with an eccentric crushing cone. A drill bit, which is a chisel or cross one, is connected with the lower end of the cone and is provided with an alloy cutter head therebelow. A casing is arranged at the outer periphery of the crushing cone, with the upper end being fixed on the submersible motor. The inner surface of the casing and the outer surface of the crushing cone are both provided with spiral protrusions. The crushing cone is a circular cone with thick upper portion and thin lower portion. The casing is a hollow circular cone with thin upper portion and thick lower portion. A water inlet pipe penetrates between the submersible motor and the crushing cone, with the lower end being equipped with a water nozzle and with the upper end being connected with a water inlet hose. The stone-crushing drill bit of the utility model is a drill bit special for a pore-forming drilling machine.
Description
One, technical field
The utility model relates to a kind of rig drill bit, particularly a kind of rig rubble drill bit of ability broken pebble.
Two, background technology:
At present, common rig driving speed in the bulk cobble is very slow perhaps can not tunnel.
Three, summary of the invention:
The utility model has remedied the shortcoming of above rig, and a kind of rig rubble drill bit of ability broken pebble is provided.
The utility model is realized through following technical scheme:
A kind of rig rubble drill bit comprises the diving gravel pump on top, and the upper end of diving gravel pump is connected with drilling rod, inhales the slurry steel pipes for two about its underpart is provided with, and inhales slurry steel pipe lower end and is provided with suction inlet, and its diving gravel pump outlet pipe upper end links to each other with drilling rod; The lower end of diving gravel pump is connected with submersible motor, and the submersible motor lower end is connected with eccentric broken cone, and the cone lower end is connected with drill bit, and its drill bit is a word or cross bit, and it has alloy cutter head; Broken cone periphery is provided with housing, and the housing upper end is fixed on the submersible motor, and the inner surface of housing and the external surface of broken cone are equipped with spiral protrusion, and broken cone is upper coarse and lower fine cone, and housing is up-thin-low-thick hollow cone body; Water inlet pipe passes the centre of submersible motor and broken cone, and its lower end is provided with water spout, and the upper end is connected with water supply hose.
The utlity model has following characteristics:
1, this rubble drill bit is owing to the broken bulk cobble of ability, and the cobble after the fragmentation extracts displacement by the diving gravel pump, so can in boulder bed, tunnel.
2, this rubble drill bit adopts the direct circulation water inlet, and anti-circulation diving gravel pump extracts the pore-forming body refuse, and pore-forming efficiency is very high.
Four, description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1, drilling rod, 2, outlet pipe, 3, the diving gravel pump, 4, water supply hose, 5, inhale the slurry steel pipe, 6, submersible motor, 7, water inlet pipe, 8, housing, 9, hole wall, 10, broken cone, 11, spiral protrusion, 12, drill bit, 13, water spout.
Five, the specific embodiment:
Accompanying drawing is a kind of specific embodiment of the utility model; This embodiment comprises the diving gravel pump 3 on top, and the upper end of diving gravel pump is connected with drilling rod 1, inhales slurry steel pipe 5 for two about its underpart is provided with; Inhale slurry steel pipe lower end and be provided with suction inlet, its diving gravel pump outlet pipe 2 upper ends link to each other with drilling rod; The lower end of diving gravel pump is connected with submersible motor 6, and the submersible motor lower end is connected with eccentric broken cone 10, and the cone lower end is connected with drill bit 12, and its drill bit is a word or cross bit, and it has alloy cutter head; Broken cone periphery is provided with housing 8, and the housing upper end is fixed on the submersible motor, and the inner surface of housing and the external surface of broken cone are equipped with spiral protrusion 11, and broken cone is upper coarse and lower fine cone, and housing is up-thin-low-thick hollow cone body; Water inlet pipe 7 passes the centre of submersible motor and broken cone, and its lower end is provided with water spout 13, and the upper end is connected with water supply hose 4.
Submersible motor drives broken cone and does eccentric motion during the utility model work; Squeeze the cobble that gets between broken cone and the housing broken; Simultaneously, submersible motor also drives following drill bit rotation driving, and the water jetting at high pressure that water inlet pipe gets into is sprayed by water spout; With the common cuts formation of rotary drilling-head, body refuse extracts displacement by the diving gravel pump.
The utility model is the target drill of pore-forming drill.
