Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of cutting units, this cutting units is applied to development machine.Particularly, this cutting units is connected on the panoramic table of development machine.This cutting units comprises cutterhead, cut deceleration device, the main shaft connecting this cutterhead and this cut deceleration device, slippage frame, the cutterhead power set be connected with this cut deceleration device and shell body; This slippage frame is arranged in this shell body slidably, and one end of this slippage frame is connected with this cut deceleration device, and these cutterhead power set are arranged in this slippage frame.Incorporated by reference to consulting Fig. 2 to Fig. 4, the concrete structure of this cutting units is as follows:
This cutting units comprises cutterhead 31, protection cylinder 32, main shaft 33, cut deceleration device 34, slippage frame 35, shaft coupling 36, cutterhead power set 37, shell body 38 and retractable driving device 39.
This cutterhead 31 is set in one end of this protection cylinder 32.This cutterhead 31 is provided with cut tooth 311, and when this cutterhead 31 rotates, this cut tooth 311 can carry out cut operation to colliery.This protection cylinder 32 is hollow cylindrical configuration, and its other end is connected with this cut deceleration device 34.This main shaft 33 is arranged in this protection cylinder 32, and one end of this main shaft 33 is connected with this cutterhead 31, and the other end is connected with this cut deceleration device 34.This main shaft 33 is for transmitting the moment of torsion from this cut deceleration device 34 to this cutterhead 31.This cut deceleration device 34 can regulate according to the rotating speed of the hardness in coal seam to this cutterhead 31.
This slippage frame 35 is slidably disposed in this shell body 36.One end of this slippage frame 35 is connected with this cut deceleration device 34.
This shaft coupling 36 and these cutterhead power set 37 to be arranged in this slippage frame 35 and can to coexist in this shell body 38 with this slippage frame 35 1 and move.These cutterhead power set 37 are connected with this cut deceleration device 34 by shaft coupling 36, and the moment of torsion needed for this cutterhead 31 is sent to this cutterhead 31.This shaft coupling 36 is accommodated in the inner with these cutterhead power set 37 by this slippage frame 35; can protect this shaft coupling 36 and this cutterhead power set 37, prevent this shaft coupling 36, these cutterhead power set 37 and this shell body 38 from rubbing, collide and damage.
This shell body 38 is hinged on the panoramic table of this development machine, and this shell body 38 is for accommodating this slippage frame 35.This shell body 38 is a tubular structure, and it has an openend and a blind end 380 relative with this openend.This slippage frame 35 to be loaded in this shell body 38 by this openend and can slide in this shell body 38.This blind end 380 place's projection a junction 381, this connecting portion 381 is hinged with this panoramic table, and this cutting units can be swung up and down by this panoramic table relatively, and can at horizontal rotation in surface under the driving of panoramic table.
This retractable driving device 39 one end is connected on this shell body 38, and the other end is connected on this cut deceleration device 34 or protection cylinder 32.Under normal circumstances, this retractable driving device 39 is in contraction state, and now, this slippage frame 35 is contained in this shell body 38.Refer to Fig. 5; when this retractable driving device 39 be in stretch out state time; this cutterhead 31, protection cylinder 32, main shaft 33, cut deceleration device 34, slippage frame 35, shaft coupling 36 and cutterhead power set 37 integrally move to the direction away from this blind end 380, make this protection cylinder 32 protruding.
Cutting units provided by the present invention adopts slippage frame and the mode be slidably connected between shell body to realize the stretching motion of cutterhead, this kind of mode instead of in prior art by flexible protection cylinder, the flexible relative spline housing of inner core, outer telescopic tube does stretching motion and realizes seesawing of cutterhead, therefore, cutting units provided by the present invention only has a protection cylinder between main shaft and cutterhead, four layers of sleeve (spline housing are provided with outside existing main shaft, flexible inner core, outer telescopic tube and flexible protection cylinder) not only there is the simple advantage of structure, the more important thing is that the unique texture of cutting units of the present invention also makes the diameter of this protection cylinder greatly reduce, and then reduce the diameter of the cutterhead be set in outside this protection cylinder, under the prerequisite not changing power of motor and deceleration device speed reducing ratio, the larger force of periphery (tangential force) that the cutterhead of cutting units provided by the present invention produces can be made, thus raising cutting efficiency.
Preferably, this cutting units also comprises adjustable ground and is arranged at lash adjusting device 4 on this shell body 38, this lash adjusting device 4 is for adjusting the glade plane space between this slippage frame 35 and this shell body 38, to ensure when this slippage frame 35 is mounted in this shell body 38 maybe when this slippage frame 35 is through use and this shell body 38 still can keep suitable gap surplus after wearing and tearing, to prevent from reducing application life because rubbing comparatively large between this slippage frame 35 and this shell body 38 between this slippage frame 35 and this shell body 38 for a long time.This lash adjusting device 4 comprises regulating element 40 and gland member 41.Correspondingly, the perisporium of this shell body 38 offers through hole 382; The perisporium of this slippage frame 35 offers the guide rail 351 corresponding with this through hole 382, when this slippage frame 35 this shell body 38 relative slides, this regulating element 40 is relative sliding in this guide rail 351, to lead to this slippage frame 35.
This regulating element 40 to penetrate in this through hole 382 and supports in this guide rail 351, and this gland member 41 to be covered on this regulating element 40 and to be locked together on this shell body 38 by locking element 42.By rotating this this gland member 41 of locking element 42 adjustable to the thrust of this regulating element 40, thus adjust the gap between this shell body 38 and this slippage frame 35.
This regulating element 40 is preferably axle, and it to penetrate in this through hole 382 and supports in this guide rail 351.This locking element 42 is preferably bolt, and this shell body 38 that ring is located at this through hole 382 periphery offers screwed hole 383, and this locking element 42 is threaded with this screwed hole 383.
Above-mentioned lash adjusting device 4 quantity can carry out increasing or reducing according to the shape of cross section of this slippage frame 35 and this shell body 38.Such as, when the cross section of this slippage frame 35 and this shell body 38 is rectangle, this lash adjusting device 4 quantity is at least four, namely on four sidewalls of this shell body 38, arranges a lash adjusting device 4 respectively.In order to improve the precision of gap adjustment, four sidewalls of this shell body 38 can arrange four lash adjusting devices 4 respectively.When the cross section of this slippage frame 35 and this shell body 38 is circular, this lash adjusting device 4 quantity is at least three, and three lash adjusting devices 4 are laid on this shell body 38 with equal central angle angle.
Be appreciated that this guide rail 351 can be save, this regulating element 40 can directly support on the perisporium of this slippage frame 35.
The invention provides a kind of development machine with above-mentioned cutting units, because above-mentioned cutting units has above-mentioned technique effect, therefore, the development machine being provided with this cutting units also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, therefore does not repeat.
