Description

Novel crushing roller of crusher

Technical Field

The utility model relates to a broken field, concretely relates to novel breaker crushing roller.

Background

Limestone needs to be used the breaker to carry out the breakage to bold limestone in process of production, and usual breaker is carried out the breakage by two crushing rollers meshing together, but because the relatively poor local broken tooth wearing and tearing of operating mode environment of crushing roller are serious, so need inspect after working to the deadline, will change the maintenance to the crushing roller that damages, change in the past and waste time and energy work efficiency and low, influence the normal use of breaker.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problem, the utility model provides a novel crusher crushing roller.

The utility model discloses a realize through following technical scheme:

the utility model provides a novel breaker crushing roller, includes the back shaft, back shaft central authorities are provided with rather than integrated into one piece's hexagonal center post, the circular external member that a plurality of closely arranged has cup jointed on the hexagonal center post, and is a plurality of the both ends of circular external member are provided with the locking fastener that the spiro union is used for fixed circular external member on the back shaft, every the even opening in the outside of circular external member has a plurality of slot, and it has one rather than the broken tooth that matches to peg graft in every slot, the root of broken tooth is opened there is a ring channel, an annular cover has been cup jointed on the ring channel, a draw-in groove has been opened in the outside of annular cover, every one side of slot is provided with a counter sink rather than the slope of lower part intercommunication, the downthehole spiro union of counter sink has a spacing bolt, spacing bolt's root sets up rather than the.

Preferably, the center of the round sleeve is provided with an insertion hole matched with the hexagonal central column, and the round sleeve is fixedly sleeved with the hexagonal central column through the insertion hole.

Preferably, the limiting bolt is an inner hexagon bolt, and the top of the limiting bolt is completely inserted into the countersunk hole.

Compared with the prior art, the beneficial effects of the utility model are that: this practicality is through cup jointing the circular external member of a plurality of on the hexagonal center post of back shaft to set up convenient to detach's broken tooth in circular external member outside, comparatively simple labour saving and time saving when maintaining broken tooth like this has improved staff's work efficiency, and through the annular cover rather than rotatory that sets up on broken tooth, can make broken tooth carry out the rotation of certain angle when broken lime stone, just so can prevent the use inhomogeneous of the just right broken tooth working face on two crushing rollers, can prolong the life of broken tooth greatly.

Drawings

Fig. 1 is a perspective view of the structure of the present invention;

FIG. 2 is a partial part-assembly schematic of FIG. 1;

FIG. 3 is another perspective view of FIG. 2;

in the figure: the supporting shaft comprises a supporting shaft 1, a hexagonal central column 2, a round sleeve 3, a locking clamping piece 4, a slot 5, crushing teeth 6, a counter bore 7, a limiting bolt 8, an annular groove 9, an annular sleeve 10 and a clamping groove 11.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, 2 and 3, a novel crusher crushing roller comprises a supporting shaft 1, a hexagonal central column 2 integrally formed with the supporting shaft 1 is arranged in the center of the supporting shaft 1, a plurality of closely arranged circular kits 3 are sleeved on the hexagonal central column 2, locking fasteners 4 screwed on the supporting shaft 1 and used for fixing the circular kits 3 are arranged at two ends of the circular kits 3, a plurality of slots 5 are uniformly formed in the outer side of each circular kit 3, a crushing tooth 6 matched with each slot 5 is inserted in each slot 5, an annular groove 9 is formed in the root of each crushing tooth 6, an annular sleeve 10 is sleeved on the annular groove 9, a clamping groove 11 is formed in the outer side of the annular sleeve 10, an inclined countersunk hole 7 communicated with the lower portion of each slot 5 is arranged at one side of each slot 5, and a limit bolt 8 is screwed in the countersunk hole 7, the root of the limiting bolt 8 is arranged in a clamping groove 11 of the corresponding annular sleeve 10.

The center of the round sleeve 3 is provided with an insertion hole matched with the hexagonal central column 2, and the round sleeve 3 is fixedly sleeved with the hexagonal central column 2 through the insertion hole.

The limiting bolt 8 is an inner hexagon bolt, and the top of the inner hexagon bolt is completely inserted into the counter sink 7.

The working principle is as follows: when the local area of the crushing teeth 6 on the crushing roller of the crusher which is regularly checked is seriously damaged, the crushing roller does not need to be taken out, the crushing roller is slowly coiled by a driving motor to rotate, the seriously damaged crushing teeth 6 are positioned in front of a maintenance window, a worker only needs to use an inner hexagonal wrench to screw out the limiting bolt 8 in the countersunk hole 7 beside the damaged crushing teeth 6, then uses a force using tool to knock the crushing teeth 6 to loosen the crushing teeth 6, takes the crushing teeth out of the slot 5, installs the root of a new crushing tooth 6 in the slot 5 with the damaged crushing teeth 6, when the crushing teeth are installed, the clamping groove 11 on the annular sleeve 10 on the crushing teeth 6 is just opposite to the bottom of the countersunk hole 7, and screws up the limiting bolt 8 for limiting and fixing, when the limiting bolt 8 is screwed up, the limiting bolt 8 is completely inserted into the countersunk hole 7 to prevent the protrusion and the abrasion of the protruding crushing teeth, so that the whole replacing process, the working efficiency of workers is improved, the crushing teeth 6 can rotate at a certain angle when limestone is crushed by the annular sleeve 10 which is arranged on the crushing teeth 6 and rotates with the crushing teeth, so that the uneven use of the working surfaces of the crushing teeth 6 which are over against the two crushing rollers can be prevented, and the service life of the crushing teeth 6 can be greatly prolonged;

when the broken tooth 6 of crushing roller and outside damage are serious, can take out the crushing roller, twist out the locking fastener 4 at both ends on the crushing roller, with the whole six arris center post 2 roll-off from back shaft 1 of circular external member 3, install new circular external member 3 that has been prepared, just so need not scrap whole damaged roller, both guaranteed the efficiency of maintaining, the holistic loss of scrapping the damaged roller of enterprise of having practiced thrift again.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
