Abstract
A wet-type hand-held coal wall drilling machine is most suitable for drilling holes in mine exploitation. The high-pressure water is used as power, the water motor directly drives the drill rod to rotate, low-pressure water discharged by the water motor is introduced into the drill bit to be discharged, power holding and dust removal are integrated, two long tails of a cable and a water pipe do not need to be towed simultaneously, and the high-pressure water discharging device is safe and reliable in mine mining operation, large in working torque, light in weight, high in efficiency, capable of greatly reducing the labor intensity of workers and wide in practicability.
Description
The present invention relates to a kind of hand water-type coal drilling machine, be particularly useful for the pit mining jewel hole, also be applicable to the occasion that needs wet drilling.
Existing hand-held wet type rib jewel hole instrument---electric coal drill or electric coal borer, all be to be power source with the motor, for eliminating the coal dust harm of bit cutting, generally all adopt and on the electric coal drill head, add a water jacket, press water is introduced hollow drill pipe, make press water from the drill bit ejection, play the effect of eliminating dust.This electric coal drill adds the hand-held jewel hole instrument of wet type rib of water-jacket typ, though can play the depositing dust effect, because of cable and water pipe operation in tow simultaneously, weight is big, uses very inconvenient.
Problem in view of prior art exists the purpose of this invention is to provide a kind of hand water-type coal drilling machine, and it can be with cable, water pipe normalizing, thereby makes hand water-type coal drilling machine easy to use, and weight saving is safe and reliable.
Hand water-type coal drilling machine of the present invention, it is made up of drill bit, housing, handgrip, water inlet pipe, it is characterized in that: be power with the water under high pressure, directly drive the drilling rod rotation with water motor, water motor is introduced the drilling rod centre bore with crossing the low-pressure water of emitting, discharge from drilling rod front end drill bit.
Hand water-type coal drilling machine of the present invention, appearance power, dedusting are that the water motor of employing can be a gear motor, also can be sliding-vane motor, piston motor, orbit motor, can also be the dynamical type impeller motor all over the body.Gear motor is made up of a pair of shaft gear, in the housing front portion of hand water-type coal drilling machine hollow shaft is housed, and the output shaft of trailing wheel and motor has tooth embedding mode to link each other.Introduce the low-pressure water path of drilling rod centre bore, can on the main shaft of water motor, offer centre bore, the dark orifice flow of low-pressure water behind motor from the housing rear portion gone into the cavity of rear-end of spindle, flows into the centre bore of hollow shaft from the centre bore of main shaft, flows into the centre bore of drilling rod again; Can also flow into the centre bore of drilling rod at last with low-pressure water along the centre bore of the inner duct on the housing antetheca through annulus introducing hollow shaft.
Hand water-type coal drilling machine of the present invention, be best suited for the pit mining perforating, the employing water under high pressure is used as power, directly drive the drilling rod rotation with water motor, to introduce the drill bit dedusting with crossing the low-pressure water of emitting through water motor, corresponding to the prior art in this technical field, do not need to drag simultaneously cable, two long-tail crust of water pipe, only keep water pipe, in exploitation perforating operation, more safer than electric power, and in light weight, operation torque is big, the efficient height can alleviate working strength of workers greatly, has practicality widely.
Description of drawings:
Fig. 1 is a principle of the invention front view;
Fig. 2 is a principle of the invention lateral view;
Fig. 3 is a kind of structure chart of the present invention;
Fig. 4 is the another kind of structure chart of the present invention.
Water motor 1, hollow twist drill rods 2, drill bit 3, handgrip 4, lever 5, inlet gate 6, water inlet pipe 7, shaft gear 8,9, fore shell 10, back cover 11, connecting flange 12, hollow shaft 13, sealing ring 14.
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Hand water-type coal drilling machine of the present invention, Fig. 1, shown in Figure 2 is a power with the water under high pressure, drives twist drill rods 2 rotations with water motor 1, water motor 1 usefulness is crossed the low-pressure water of emitting introduce the drilling rod centre bore, discharges from drilling rod front end drill bit 3, in order to dedusting.Insert in the water motor 1 rear end of drilling rod 2, links to each other with the driving shaft of water motor 1, by water motor 1 driven rotary, the front end of drilling rod 2 has drill bit 3, and the shell of water motor 1 is provided with two handgrips 4, and water motor 1 is provided with water inlet pipe 7, inlet valve 6 is by lever 5 controls that are contained on the handgrip.Water motor 1 can be a gear motor, also can be sliding-vane motor, piston motor, and orbit motor can also be the dynamical type impeller motor.Shown in Figure 3, what water motor 1 adopted is gear motor, by a pair of shaft gear 8,9 by the pressure transferring power, machine shell is by fore shell 10, back cover 11, connecting flange 12 combines, hollow shaft 13 is housed in the fore shell 10, its rear end is connected with the spindle nose of gear 8 with tooth embedding mode, the a place is the tooth embedding among the figure, the axle of gear 8 is a main shaft, also be hollow shaft, communicate that the rear end that gear is 8 is inserted in the hole of matching of back cover 11 with the centre bore of hollow shaft 13, and facing to a cavity c, gear motor two gear low-pressure sides have dark hole b to communicate with cavity c, make the postrotational low-pressure water of driven wheel flow into cavity c through dark hole b, again through the axle center hole of gear 8 in the axis hole of hollow shaft 13, the afterbody of drilling rod 2 is inserted in the centre bore of hollow shaft 13, and the centre bore of drilling rod 2 is relative with the centre bore of gear 8.The low pressure water route of crossing through water motor 1 usefulness can also be another kind of form of structure, shown in Figure 4, still link with the output shaft of water motor 1 with tooth embedding mode, d is the tooth embedding among the figure, two seals 14 are equipped with in the outside of hollow shaft 13, be divided into a sealed annulus e, at hollow shaft 13 endoporus middle part an annulus g is arranged, communicate with space e by radial hole, the inner duct f of low pressure water route on fore shell 10 injects annulus e, flow to space g again, the afterbody of drilling rod 2 is inserted in the centre bore of hollow shaft 13, and with the corresponding place of space g, drilling rod 2 afterbodys have radial hole, make water flow into drilling rod 2 centre bores from space g, discharge from drilling rod front end drill bit 3 through radial hole.
