A kind of double-geared roller crusher granularity and tooth plate wear-compensating governor motion
Technical field
The utility model relates to a kind of double-geared roller crusher discharging-material size and tooth plate wear-compensating governor motion.
Background technology
Existing double-geared roller crusher, the centre-to-centre spacing of two discaling rolls is generally fixed, and discharging-material size can't be regulated; Along with the wearing and tearing of the crushing teeth on the discaling roll tooth plate, two gap of tooth roller are increasing, cause the disintegrating machine discharging-material size also increasing; For guaranteeing granularity requirements; Just must change tooth plate, so the stock utilization of tooth plate is very low, production cost increases.A kind of way is to set up a following operative minor in two discaling roll middle lower portion; Following crushing teeth on the following operative minor respectively with two discaling rolls on the staggered interlock of crushing teeth; Material is through between two discaling rolls and twice fragmentation between discaling roll and following operative minor; Thereby the discharging-material size that makes disintegrating machine reduces to prolong the service life of tooth plate, but this time operative minor also is fixedly can't regulate compensation, also necessary replacing after discaling roll tooth plate and following crushing teeth may wear to a certain degree.
Summary of the invention
The purpose of the utility model provides a kind of mechanism that realizes operative minor up-down adjustment under the disintegrating machine, to adjust material granularity and compensation crushing teeth wear extent, improves the utilization rate of tooth plate material as far as possible, reduces production cost.
The technical scheme of the utility model is:
A kind of double-geared roller crusher granularity and tooth plate wear-compensating governor motion; This governor motion comprises the following operative minor of being made up of the following crushing teeth and the adjustment screw rod that is positioned at the support two ends that are connected on the support; Wherein, the two ends vertical direction perforate of support, an end of adjustment screw rod passes this hole down; The other end passes above the end frame of disintegrating machine, and on the end frame, upper gasket, adjustment nut and locking nut is set successively.
Further be; The two ends of said support are connected on two adjustment racks; Form " worker " font, the two ends vertical direction perforate of adjustment rack, an end of four adjustment screw rods passes corresponding hole respectively down; The other end passes above the end frame of disintegrating machine respectively, and on the end frame, upper gasket, adjustment nut and locking nut is set successively.
The beneficial effect of the utility model is: in above-mentioned double-geared roller crusher granularity and the tooth plate wear-compensating governor motion; Just can drive the adjustment screw rod through rotation adjustment nut and move up and down, the adjustment screw rod drives support and moves up and down, and adjusts the size that screw rod exposes and make it equal through measuring; Guarantee that operative minor is not crooked after adjusting down; After adjustment is accomplished, must be with locking nut screwing, to guarantee operative minor invariant position down in service.The utility model makes down the operative minor can up-down adjustment through structural design; Through regulating down the operative minor position; Can regulate discharging-material size, and after discaling roll tooth plate and following crushing teeth wear and tear, can compensate its wear extent, thereby continue to guarantee that discharging-material size meets the requirements; Reach the utilization rate that as far as possible improves the tooth plate material, reduce the purpose of production cost.
Description of drawings
Fig. 1 is the structural representation of double-geared roller crusher granularity and tooth plate wear-compensating governor motion among the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of double-geared roller crusher granularity and tooth plate wear-compensating governor motion, this governor motion comprise the following operative minor of being made up of the following crushing teeth 1 and the adjustment screw rod 3 that is positioned at support 2 two ends that are connected on the support 2; Wherein, the two ends of support 2 are connected on two adjustment racks 7, form " worker " font; The two ends vertical direction perforate of adjustment rack 7, an end of four adjustment screw rods 3 passes corresponding hole respectively down, and the other end passes above the end frame 8 of disintegrating machine respectively; And on end frame 8, upper gasket 4, adjustment nut 5 and locking nut 6 are set successively, because design reasons or tooth plate wear and tear when causing discharging-material size excessive, at first unclamp each locking nut 6 when disintegrating machine; The nut 5 of four adjustment of rotation synchronously moves up operative minor as far as possible; Drive support 2 upper and lower crushing teeths 1 and also move up, the gap under reducing between crushing teeth 1 and the discaling roll, thus reduce discharging-material size; After adjusting to the appropriate location; Measure and finely tune measure-alike that four adjustment screw rods 3 expose, guarantee that operative minor is not crooked down, at last with locking nut 6 lockings; When if the too small needs of disintegrating machine discharging-material size increase; Its step just needs reverse rotation adjustment nut 5 that adjustment screw rod 3 is moved down with top the same, and driving down, operative minor also moves down; Gap under increasing between crushing teeth 1 and the discaling roll is to increase discharging-material size.
