The specific embodiment:

The utility model combination specific embodiment further specifies as follows referring to accompanying drawing: a kind of multi-functional primary-secondary drill, its general structure accompanying drawing 1, it is to install base 7, middle seat ring 5, interior rail ring gear 4, three-dimensional integrated positioning clutch 3 in cylinder-like shell 31 from bottom to up successively, and female drill bit 2 is installed on the three-dimensional integrated positioning clutch 3.

Female drill bit 2 is referring to accompanying drawing 1,2, and top is loudspeaker bucket 8, and the bottom is uniform three the axial sub-drill bits 1 of symmetry on the circumferential slopes of cylinder 11, loudspeaker bucket 8; Be fixedly connected with defeated mud blade 39 on loudspeaker bucket 8 inclined-planes between the sub-drill bit 1, referring to accompanying

drawing

3,4; In cylinder 11 inner chambers spiral reel 6 is housed axially, on the base 7 of spiral reel 6 lower ends and the shell 31 mud mouth 29 is arranged.Installing rack 30 is arranged at base 7 bottoms.Female drill bit head and cylinder afterbody have sealing ring to prevent that earth from infiltrating, and the lubrication oil in the primary-secondary drill oozes out.

Sub-drill bit structure is referring to accompanying drawing 1,2, each sub-drill bit 1 is to be installed on the present tube 40 via upper bearing (metal) 41, lower bearing 38 respectively by sub-drill bit shaft 9 upper and lower ends, seat tube 40 is fixed on female drill bit 2, sub-drill bit shaft 9 upper end warp beam sleeves 42 connect firmly helical blade 44, and helical blade 44 upper ends and periphery connect firmly several alloy blades 43.Sub-drill bit shaft 9 lower ends connect planetary gear 10, and planetary gear 10 is meshed with interior rail ring gear 4 on being fixed on shell 31.

Female drill bit 2 is to install in the shell 31 via three-dimensional integrated positioning clutch 3, and referring to accompanying drawing 1,2, the structure of three-dimensional integrated positioning clutch 3 is referring to accompanying drawing 5,6.Three-dimensional integrated positioning clutch 3 is by on the ring-type backrest wheel carrier 35, three upright pulleys 37 are installed along the ring-type circumference uniform distribution separately in following two ends, 34, three horizontal trolleys 36 are installed along the ring-type circumference uniform distribution in backrest wheel carrier 35 middle parts, backrest wheel carrier 35 is fixed on the shell 31, going up upright pulley 37 for three touches with female drill bit 2 sliding rolling, three down upright pulleys 34 touch with ring-type slide plate 33 sliding the rolling that are fixed on female drill bit 2, female drill bit 2 is formed, the running of following location, three horizontal trolleys 36 roll with female drill bit 2 level cunnings and touch, make the location running of female drill bit 2 horizontal directions, thereby female drill bit 2 is realized the running of three-dimensional location by three-dimensional integrated positioning clutch 3.

In seat ring 5 tops be uniformly distributed along the circumference three horizontal location pulleys 32 be installed, referring to accompanying drawing 7, touch horizontal location pulley 32 and the horizontal trolley 36 common horizontal location that form female drill bit 2 with cylinder 11 sliding the rolling of female drill bit 2.

The transmission mechanism of multi-functional primary-secondary drill is vertically installed motor 18 referring to accompanying drawing 1,2 in the base 7, motor 18 can be used electro-motor, also can adopt hydraulic motor, or air motor.The last shaft extension end of motor 18 connects firmly driven wheel 15, and it drives female drill bit 2 through reduction gearing 14 and gear wheel 13 engagements that are loaded on female drill bit 2 cylinders 11 lower ends; During female drill bit 2 rotations, drives interior rail ring gear 4 circumference that three sub-drill bits 1 connect firmly and rotate on shell 31,, thereby sub-drill bit 1 is rotated because the planetary gear 10 of axle 9 lower ends of sub-drill bit 1 is meshed with interior rail ring gear 4; The travelling gear 19 that axle 17 lower ends of reduction gearing 14 connect firmly is through gear 22 engagements of carrier gear 21 with hollow cylinder axle 23 lower ends of spiral reel 6, thereby motor 18 also drives 6 runnings of spiral reel simultaneously.

The setting of spiral reel 6 is for mud extraction fast from female drill bit 2 cylinders 11 inner chambers, guarantees the high efficiency of multi-functional primary-secondary drill.The structure of spiral reel 6 is referring to accompanying drawing 1, it is by connecting firmly helical blade 27 on the hollow cylinder reel axle 23, gear 22 is equipped with in reel axle 23 lower ends, be installed on the fixed axis core 25 via upper and

lower bearing

28,24 respectively in reel axle 23 upper/lower terminals, there is helicitic texture fixed axis core 25 lower ends, are fixed on the base 7 through locking nut 26.Spiral reel 6 is sent the earth that multi-functional primary-secondary drill excavates outside the drill bit from mud mouth 29.

This experiment Multifunction primary-secondary drill is contained on the digging machine arm, be particularly suitable for city and rivers Haiti constructing tunnel, do not allow to adopt the engineering of blasting method, as long as opening motor 18 will rotate, as mentioned above, driven wheel 15 on the motor drive shaft drives female drill bit 2 and sub-drill bits 1, drive helical blade 44 and alloy knife 43 crushed rock simultaneously after, by the defeated mud blade on the loudspeaker bucket 8 39 earth is forwarded to afterbody.Drive travelling gear 19 when shaft gear 17 is driven and drive spiral reel 6 through carrier gear 22, relay transfers out defeated mud mouth 29 to earth fast.Female drill bit 2 is just changeing, 2 counter-rotatings of sub-drill bit, and gentle like this rocking of drill bit is used to power, because the diameter of sub-drill bit 1 is less than female drill bit 2, so resistance is very little, than the laborsaving several times of the common big drill bit of prior art, power is again greater than several times.The utility model how available two is to the level Four deceleration device, and four to eight simultaneously synchronous collectives of motor drive big drill bit gear, can certainly reduce to one group of device, drive big drill bit gear with a motor.

The utility model is owing to uniform a plurality of sub-drill bits on female drill bit, and be furnished with several alloy blades on each sub-drill bit, when the primary and secondary drill bit all rotates, can form boring, mill, bore tens cutting points, therefore the utlity model has boring, mill, bore multiple function, the cutting output of each cutting point is very little, drag loading is little, and cutting speed can be accelerated; And each alloy blade cutting is not once cut and cooling by turns with regard to half or a greater part of time, also helps quickening cutting.The metal works on one meter wide plane of processing needs cutting several thousand cuttves with metal-planing machine processing usually, time-consuming several hrs, even tens hours, and, only need cutter processing to get final product with the multi-functional primary-secondary drill of the utility model of a rice diameter.
