And use the rotary drill of various ways such as water exploring drill machine, rigs against outburst, jumbolter in a large number in the colliery, because the coal mining geology condition is very complicated, geological structure is extremely unstable, in creeping into, soft rock usually runs into local solid rocks such as dirt band, rotary drill can't overcome, other form rigs be must change, the complexity of equipment setting and the decline of operating efficiency caused.
The utility model purpose
The purpose of this utility model is exactly that a kind of compliance of rotary drill to solid rock that improves when guaranteeing high drilling efficiency will be provided, and the service condition of rotary drill is expanded greatly.
The utility model content
The purpose of this utility model is achieved in that it is made of exciting assembly, telescopic central axis and housing three parts, and housing and rig shell are fastenedly connected or adopt integrated design; The exciting assembly is made up of stator, vibrating reed and brute spring, and stator is fixed on the housing, and vibrating reed is fixed on the outer shaft of telescopic central axis, and spring is fixed between stator and the vibrating reed; Telescopic central axis is made up of interior axle and outer shaft, and interior axle is the output shaft of drill motor part, and outer shaft is the output shaft of rig complete machine.
Distinguishing feature
Distinguishing feature of the present utility model is:
1, realizes vibration by frame for movement, under the prerequisite that does not change rotary drill basic structure, improved the compliance of rig rock;
Therefore 2, the inside and outside shaft torque transfer mode of exciting assembly tooth form in the vibrating mechanism and telescopic central axis all has multi-formly, can combine multiple vibrator form;
3, mechanism has adaptivity to the rock load, and when creeping into coal or soft rock, rate of penetration is fast, and the thrust loading that rig bears is little, and the exciting assembly does not produce vibration, and rig takes pure revolution to break the rock mode; When creeping into than hard rock, rate of penetration slows down, and the thrust loading that rig bears increases, and the exciting assembly produces vibration, and rig takes rotary vibration to break the rock mode;
4, use in a large number in the colliery under the rotary drill condition of various ways such as water exploring drill machine, rigs against outburst, jumbolter, the utility model plays an important role at the complex geological condition of coal, half coal petrography and soft rock;
5, it is simple and compact for structure, and difficulty of processing is low, is easy to realize.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
A kind of mining slewing drilling machine mechanical oscillation mechanism, this mechanism is divided into exciting assembly, telescopic central axis and housing three parts, as shown in Figure 1, outer shaft 1, vibrating reed 2, brute spring 3, stator 4, interior axle 5, housing 6 and flat key 7.Housing 6 is fastenedly connected or adopts integrated design with the rig shell.The exciting assembly is made up of stator 4, vibrating reed 2 and brute spring 3, is the stator structural representation as Fig. 2, and Fig. 3 is the vibration plate structure schematic diagram, and stator 4 is fixed on the housing 6, and effect is to bear vibration force and propulsive force; Vibrating reed 2 is fixed on the outer shaft 1 of telescopic central axis, and effect is that the vibration force of rig and rotational torque are passed to drilling tool; Spring 3 is fixed between stator 4 and the vibrating reed 2, and effect is to carry out the broken rock of pure revolution under rig bears the situation of less thrust loading, carries out the broken rock of rotary vibration under rig bears situation than the high thrust load.Telescopic central axis is made up of interior axle 5 and outer shaft 1, shown in Fig. 4,5, can transmitting torque and do not relatively rotate, and can slide to axial again and do not transmit axial force.When vibrating mechanism and rig integrated design, interior axle 5 is output shafts of drill motor part, effect is that the rotational torque with motor passes to outer shaft, and outer shaft 1 is the output shaft of rig complete machine, and effect is that the vibration force of rig, propulsive force and rotational torque are passed to drilling tool.The utility model can also be processed into independently mechanical vibrator, the interior axle and the coaxial fixed installation of the output shaft of rig of vibrator, the housing of vibrator and the fixed installation of rig housing during use.
Stator 4 is fixedly connected on the housing 6 by key or other modes, and vibrating reed 2 is fixedly connected on the outer shaft 1 by key or other modes.Interior axle 5 is output shafts of motor.When axle 5 rotates in motor drives, give outer shaft 1 with transmission of torque by cooperating shown in Fig. 8,9,10 down.The thrust of bearing when rig is during less than the pretightning force of spring 3, stator 4 the cooperation of spring force and thrust with under separate with vibrating reed 2, outer shaft 1 is done pure gyration.The thrust of bearing when rig is during greater than the pretightning force of spring 3, stator 4 the cooperation of spring force and thrust with under contact with vibrating reed 2, each tooth on the vibrating reed 2 under torque with stator 4 on each tooth mesh successively, drive outer shaft 1 and produce vibration, so outer shaft 1 is done the rotary vibration motion under the synergy of motor and exciting assembly.
