Abstract

The utility model discloses a roller for a double-roller type sand making machine, relating to the technical field of crushing equipment. The roller comprises a roller shaft 2, a roller drum 4, a hub 6, a taper sleeve 10 and a fixed bolt 11. The roller has the characteristics of simple structure, convenience in maintenance, long operation period, and the like, is matched with the double-roller type sand making machine, can be used for making sand for buildings by using materials such as gravels and cobblestone, can also be used for a front crushing mill of a grinding system, and can be widely applied to the fields of buildings, building materials, mines and the like.

Description

The roller that a kind of Double roller type sand maker is used

Technical field

The utility model relates to disintegrating apparatus technical field, the roller that particularly a kind of Double roller type sand maker is used.

Background technology

In prior art, the roller that Double roller type sand maker is used, mainly contains two kinds of forms, and the one, one piece casting type is cast into one by roller and hub and main shaft that is:; Another kind is that heap welds roller on hub, to obtain the roller face of high abrasion.The roller of above-mentioned two kinds of modes, all exists the inconvenient defect of maintenance.Chinese patent " assembled single-roller sand producer apparatus " (number of patent application is 200810229948.9), in device, be to be cemented in above frame with bearing block, in bearing block, packing bearing into, main shaft two end vicinity are enclosed in dead eye, and main shaft two end places are fixed belt pulley and weighting distribution wheel respectively; A left side for semicircular arc half wheel and right half wheel are corresponding is fastened on a segment length in the middle of main shaft, and left half wheel and right half wheel become assembled single-roller with bearing up pulley bolted, and left half wheel and the right half semicircle gusset of taking turns and the ring flange on main shaft carry out fastening with connecting bolt; Squeeze sand plate two ends fastening sliding sleeve, sliding sleeve is enclosed in sliding sleeve plate hole, tightens bolt one end and is enclosed in sliding sleeve, tighten the threaded portion of bolt and screw in spiral shell plate be screwed in together with, the lower end of sliding sleeve plate and spiral shell plate is cemented in respectively on the crossbeam above frame; This device have extend roller service life 2-3 doubly, on year-on-year basis under, saving energy is 30-40%, increases sand output processed and reaches more than two times.

Summary of the invention

Technical problem to be solved in the utility model is to provide the roller that a kind of sand equipment processed simple in structure, easy to maintenance, that the cycle of operation is long is used.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is the roller that a kind of Double roller type sand maker of design is used: comprise roll shaft 2, also include roller 4, hub 6, tapered sleeve 10 and set bolt 11;

A, described roller 4 are cylindrical shells that have inner groove, and its endoporus two ends are respectively arranged with the bulge loop 5 of the inclined plane shape that outside diameter is large, inside diameter is little;

B, described hub 6 are cylindrical shells that a cross section is side " soil " word shape, and " one " of being somebody's turn to do " soil " word shape cylindrical shell lower end is the frustum of a cone big end down, that coordinate with bulge loop 5; " one " of being somebody's turn to do " soil " word shape cylindrical shell upper end is cylinder table 9, and its periphery has two above screws;

C, described tapered sleeve 10 are circular frustums of a cone, and its periphery has two above bolts hole;

D, described hub 6 are fixed on roll shaft 2, and roller 4 is sleeved on hub 6, and tapered sleeve 10 is sleeved on the upper end of " soil " word shape cylindrical shell " I ", by set bolt 11, itself and the cylinder table 9 of " soil " word shape cylindrical shell upper end are combined as a whole.

Between upper and lower two " " of " soil " word shape cylindrical shell of hub 6, be also provided with more than two reinforcements 8.

The roller that Double roller type sand maker of the present utility model is used, adopts the mode that roller and hub are separated, and utilize cone match to realize location and fixing, thereby its structure is comparatively simple, easy to maintenance; Meanwhile, the wall thickness of roller can be done thicklyer, both can reduce maintenance number of times, extends the cycle of operation, reduces operating cost, also can relatively reduce the waste of roll surface precious alloy.

Fig. 1 is main cross-sectional schematic of the present utility model.

In figure: the 1st, shaft coupling, the 2nd, roll shaft, the 3rd, left shaft holder, the 4th, roller, the 5th, bulge loop, the 6th, hub, the 7th, linking bond, the 8th, reinforcement, the 9th, cylinder table, the 10th, tapered sleeve, the 11st, set bolt, the 12nd, right bearing seat.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.Explanation is below to adopt the mode exemplifying, but protection domain of the present utility model should not be limited to this.

The present embodiment is to consist of roll shaft 2, roller 4, hub 6, tapered sleeve 10 and set bolt 11.

Roller 4 is cylindrical shells that have inner groove, its slightly indentation of endoporus two ends, and be respectively arranged with the bulge loop 5 of the inclined plane shape that outside diameter is large, inside diameter is little.

Hub 6 is cylindrical shells that a cross section is side " soil " word shape, and middle through hole is installed on stair-stepping roll shaft 2, by this example of linking bond 7(employing flat key, also can adopt spline or other connection form) be connected into integral body; " one " of " soil " word shape cylindrical shell lower end of hub 6 is frustums of a cone that coordinate with the bulge loop 5 of roller 4 one sides, and it is big end down; " one " of " soil " word shape cylindrical shell upper end of hub 6 is cylinder table 9, and its periphery has two above screws; Between upper and lower two " " of " soil " word shape cylindrical shell of hub 6, be also provided with more than two reinforcements 8.

Tapered sleeve 10 is frustums of a cone circular, that coordinate with the bulge loop 5 of roller 4 opposite sides, and its periphery has two above bolts hole.

Roller 4 is sleeved on hub 6, by the frustum of a cone of " soil " word shape cylindrical shell lower end and the bulge loop of roller 4 left ends 5 left sides, location of hub 6; Tapered sleeve 10 is sleeved on the upper end of " soil " word shape cylindrical shell " I " of hub 6 according to the direction of left side microcephaly, the right major part, the right sides, bulge loop 5 location of its taper seat and roller 4 right-hand members, and by set bolt 11, the cylinder table 9 of " soil " word shape cylindrical shell upper end of itself and hub 6 is combined as a whole.

The roller that Double roller type sand maker of the present utility model is used, both can be used as drive roll, also can be used as live-roller and used.Before use, be arranged in Double roller type sand maker, allow the two ends of roll shaft 2 be threaded onto in left shaft holder 3 and right bearing seat 12, and shaft coupling 1 is installed on to the input of roll shaft 2.

After using a period of time, after roller 4 has worn and torn, need maintenance to change, now, roller is split out, Panasonic's set bolt 11, then by roller 4 by pushing away from left to right, can be by roller 4 together with tapered sleeve 10 by taking off on hub 6, by new roller 4, the right-hand member by hub 6 pierces into left again, then, tapered sleeve 10 is pierced into, fixing by set bolt 11.

The roller that Double roller type sand maker of the present utility model is used, supports the use with Double roller type sand maker, can be used for utilizing the materials such as sandstone, cobblestone to prepare sand for building, also can be used for the preposition broken mill of grinding system; Can be widely used in the fields such as building, building materials, mine.
