Description
Technical field
The utility model relates to a kind of mining electric hammer and bores.
Background technology
Mine is in various stone head construction operations, and the general perforating equipment that adopts has two kinds, and a kind of is the perforating of coal petrography electric drill, and another kind is the air drill perforating.Present known new type mining coal petrography electric drill (CN200320113326.2) volume is big, and difficulty is moved in operation.The deficiency that other has mine explosion-suppression to impact coal petrography electric drill (CN200520083482.8) is: impulsive force is little, can only be used for beating coal eye or softer rock, runs into the bigger rock of hardness ratio, and efficient is very low, and accessory is fragile.Air drill is to be specifically designed to the rock perforating, but needs fixedly auxiliary facility such as large-scale air compressor machine, long-distance pipe.Because the load in each construction operation place is unfixing, change is frequent, so air compressor machine is low load with strong power often, and the cost height, waste is big, and utilization rate is lower.
In addition, the various electric hammers of producing on the market: the one, rated voltage 220 volts (single-phase) becomes the voltage of joining with the mine site operation and does not match; The 2nd, power is little, and is not explosion-proof, is only limited to small-sized installation or finishing use on ground, can not be used for the perforating of mine rock and use.
The utility model content
The utility model purpose is to provide a kind of mining electric hammer to bore, and drill bit is subjected to percussion hammer simultaneously in rotation, improves rock perforating efficient.
To achieve these goals, the utility model adopts following technical scheme: a kind of mining electric hammer bores, and comprises housing, handle, motor, drill adapter, also comprise deceleration hammering case, deceleration hammering case comprises cylinder, and cylinder is provided with gear cylinder, and gear cylinder and motor are in transmission connection; Cylinder front end and drill adapter are fixed, and are provided with percussion hammer and piston in the cylinder successively, are provided with air cavity between percussion hammer and the piston, are provided with spring between percussion hammer and the drill adapter, and piston rear end and motor are in transmission connection by offset assembly.
Described piston rear end Hinged piston bar, the rear end and the eccentric rod on the eccentric wheel of piston rod are hinged, eccentric wheel one side circumference be provided with tooth and with the motor gear engagement that is in transmission connection with motor; Gear cylinder and travelling gear engagement, travelling gear and reduction gearing are in transmission connection, and reduction gearing and motor are in transmission connection by motor gear.
Described motor is 127 volts of explosion separation motors of three-phase.
Described electric hammer is drilled with supporting seat.
The utility model is simple in structure, cheap for manufacturing cost; Use the mine site operation to become 127 volts of (three-phase) voltages of joining, safe and reliable; Move flexibly, easy to operately can hand use, also can support use, the rock perforating is remarkably productive, saves cost, reduces consuming the efficient height.
Description of drawings
Fig. 1 is the structural representation of the inner drive connection of the utility model.
The specific embodiment
Embodiment: mining electric hammer as shown in Figure 1 bores, and comprises housing, handle, motor, drill adapter 1, supporting seat, deceleration hammering case, and motor is 127 volts of explosion separation motors 11 of three-phase.Deceleration hammering case comprises cylinder 4, and cylinder 4 is provided with gear cylinder 5, gear cylinder 5 and travelling gear 6 engagements, and travelling gear 6 is in transmission connection with reduction gearing 9, and reduction gearing 8 is in transmission connection by motor gear 10 with motor 11.
Cylinder 4 front ends and drill adapter 1 are fixing, be provided with percussion hammer 3 and piston 7 in the cylinder 4 successively, be provided with air cavity between percussion hammer 3 and the piston 7, be provided with spring 2 between percussion hammer 3 and the drill adapter 1, piston 7 rear end Hinged piston bars, eccentric rod on the rear end of piston rod and the eccentric wheel 8 is hinged, eccentric wheel 8 one side circumference be provided with tooth and with motor gear 10 engagements that are in transmission connection with motor 11.
During work, connect power supply earlier, install drilling rod, hold control crank, aiming at needs the jewel hole position, pull the running of hand switch starter motor then, by the deceleration that cooperatively interacts between inner each gear of deceleration hammering case, drive the rebound effect that rotation of cylinder and drill bit and eccentric wheel drive reciprocating motion of the pistons compressed air and spring, promote percussion hammer and clash into the drill bit top repeatedly, force drilling rod under situation about can rotate, can vibrate again, thereby reach rock jewel hole effect fast.
