Description
Technical field
The utility model relates to mining equiment field, particularly relates to a kind of dust-proof mantle rotary swing structure.
Background technology
Gyratory crusher is a kind of mining machinery for broken building stones, and its operation principle drives mantle main shaft group swing campaign by eccentric stiffener, and the cone liner plate of determining in the mantle liner plate in mantle main shaft group and frame cooperatively interacts broken building stones.And in broken building stones, building stones can be mingled with a large amount of dust, therefore dust preventing component is set between mantle main shaft group and eccentric stiffener, enters in eccentric stiffener in order to stop dust.But the dust-proof effect of the dust preventing component of existing gyratory crusher is not good, and its reason is: gyratory crusher can run into when broken building stones and be difficult to broken ore, as iron ore; Therefore the mantle main shaft group in gyratory crusher needs to move axially to adjust crusher chamber size, and leak through iron ore, this process was called iron.But crossing in iron process, mantle main shaft group moves axially, and existing dust preventing component cannot adjust, and causes dust-proof effect in this process not good thereupon, eccentric stiffener is easy to press from both sides dirt, affects device fabrication.
Summary of the invention
In order to solve the problem, the purpose of this utility model is the mantle rotary swing structure providing a kind of good dustproof effect.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of dust-proof mantle rotary swing structure, comprises mantle main shaft group, and for driving the eccentric stiffener of mantle main shaft group; Described mantle main shaft group comprises main shaft, and is set in the movable cone outside main shaft, and bearing location and installation is passed through in eccentric stiffener in main shaft lower end; The lower end of described movable cone is provided with dustproof groove, and the dust-proof draw-in groove communicated with it is established in the lower end of dustproof groove, and the movable cone of dust-proof draw-in groove lower end is also provided with dust ring baffle ring; Main shaft dust preventing component is provided with between described mantle main shaft group and eccentric stiffener, main shaft dust preventing component comprises the dust proof tube be fixed on eccentric stiffener, and the dust ring be set in outside dust proof tube, the upper end of dust proof tube is in the dustproof groove of movable cone, and dust ring is positioned in the dust-proof draw-in groove of movable cone by dust ring baffle ring.
As preferably, described dust proof tube upper end open place is provided with gear outermost layer of skin circle; Gear outermost layer of skin circle is dished out from the upper end open of dust proof tube for preventing the lubricating oil in eccentric stiffener, also has certain dust-proof effect simultaneously.
As preferably, dust ring is the torus be made up of wear resistant nylon, and the ring body section of dust ring radially tilts in direction; When mantle main shaft group moves axially relative to eccentric stiffener, dust ring moves together along with mantle main shaft group, and dust ring ring body radially direction tilts to be convenient to movable cone to drive it to move axially.
The utility model adopts technique scheme, and be provided with main shaft dust preventing component between the mantle main shaft group of this mantle rotary swing structure and eccentric stiffener, the dust proof tube in main shaft dust preventing component is fixed on eccentric stiffener, and dust proof tube upper end is in the dustproof groove of movable cone; Dust ring is set in the outside of dust proof tube, and dust ring is positioned in the dust-proof draw-in groove of movable cone by dust ring baffle ring.Owing to being located by connecting between dust ring and movable cone, cross in iron process at gyratory crusher, mantle main shaft group moves axially, and the inside of dust ring moves axially along the outer side surface of dust proof tube; In the process, dust ring the inner offsets with dust proof tube all the time, and outer end is located by connecting with movable cone all the time, and dust cannot enter in eccentric stiffener in the process.Namely this main shaft dust preventing component can adjust along with the movement of mantle main shaft group, thus ensures its dust-proof effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
The dust-proof mantle rotary swing structure of one as shown in Figure 1, comprises mantle main shaft group, and for driving the eccentric stiffener 5 of mantle main shaft group; Mantle main shaft group comprises main shaft 31, movable cone 32 and mantle liner plate 33, and main shaft 31 lower end is arranged in eccentric stiffener 5 by self-aligning roller bearing 311.The mid diameter of described main shaft 31 is greater than its two ends diameter, the taper type that movable cone 32 is large in the little lower end diameter of upper end diameter, and the axle center place of movable cone 32 is provided with spindle hole, and movable cone 32 is set in the outside in the middle part of main shaft 31; The lower surface of movable cone 32 is provided with dustproof groove 321 along the spindle hole in the middle part of it, and the dust-proof draw-in groove 322 communicated with it is established in the lower end of dustproof groove 321, and the movable cone 32 of dust-proof draw-in groove 322 lower end is also provided with dust ring baffle ring 323.
Main shaft dust preventing component is provided with between described movable cone 32 and eccentric stiffener 5, main shaft dust preventing component comprises lower end and is fixed on dust proof tube 34 on eccentric stiffener 5, and the dust ring 35 be set in outside dust proof tube 34, wherein dust ring 35 is the torus be made up of wear resistant nylon, and toric ring body section radially direction tilts.Described dust proof tube 34 upper end open place is provided with gear outermost layer of skin circle 36, gear outermost layer of skin circle 36 is between dust proof tube 34 upper end and movable cone 32, gear outermost layer of skin circle is dished out from the upper end open of dust proof tube for preventing the lubricating oil in eccentric stiffener, also has certain dust-proof effect simultaneously.
