Abstract

The utility model discloses a double -roll crusher belongs to the mining machinery field, including organism and the broken roller set of setting in the organism, broken roller set is rented including initiative roller set and driven roll, the drive roll roller set is including the initiative roller and rather than the initiative roller through the key -type connection, passive roller set includes passive roller and rather than the passive roller through the key -type connection, its characterized in that: the initiative roller is all established on the organism through bearing saddle with passive roller both ends, a coexist plane and being parallel to each other of the axial lead of initiative roller and passive roller, be equipped with spring assembly no. 1 between initiative roller set and the passive roller set, be equipped with spring assembly no. 2 between passive roller set and the frame, spring assembly no. 2 is connected to closing device, through setting up the effect of mutually supporting of two sets of springs for roller automatic balance rotational speed, solved current double -roll crusher because the automatic balance rotational speed is slow, lead to the problem that breaker crushed material material granularity is inhomogeneous and split garrulous inefficiency.

Description

A kind of double-roll crusher

Technical field

This utility model is related to mining machinery field, more particularly, to a kind of double-roll crusher.

Background technology

Double-roll crusher (oppositely rolling roller crusher double-roll crusher double-roll crusher) is applied in mine Ore, water Mud, chemical industry, electric power, metallurgical, building materials, the industrial department such as refractory material crushes medium-hard material, such as limestone, and slag is burnt Charcoal, broken in the material such as coal, operation in small, broken bits.

This serial oppositely rolling roller crusher is mainly made up of running roller, running roller spring bearing, compression and adjusting means and driving The part such as device forms.

The regulation of discharging-material size:Equipped with wedge shape or pad adjusting means between two running rollers, the top of Wedge device is equipped with tune Whole bolt, when voussoir is pulled upwardly by adjustment bolt, movable running roller is lifted off fast pulley by voussoir, and that is, two running roller gaps become big, Discharging-material size becomes big, and when voussoir is downward, movable running roller two-wheeled gap in the presence of holddown spring diminishes, and discharging-material size becomes Little.Gasket device is to adjust discharging-material size size by increasing and decreasing the quantity of pad or thickness, two running rollers when increasing pad Gap becomes big, and when reducing pad, two running roller gaps diminish, and discharging-material size diminishes.

At present, double-roll crusher in use, when blanking is uneven, the roller of skew, due to can not moment automatic Balancing speed, leads to crusher in crushing raw meal particle size uneven, and crushing efficiency twists low.

Utility model content

Goal of the invention of the present utility model is：For above-mentioned problem, a kind of double-roll crusher is provided, passes through Two groups of spring effects of cooperating are set, accelerate roller autobalance rotating speed, solve existing double-roll crusher due to certainly Dynamic balancing rotating speed is slow, leads to crusher in crushing raw meal particle size uneven and splits the low problem of broken efficiency.

The technical solution adopted in the utility model is as follows：

Double-roll crusher of the present utility model, including body and the broken roller group being arranged in body；Described breaker roll Group includes active roller group and driven roll is rented, and described drive roll roller group includes initiative roll shaft and passes through bonded drive roll with it Son；Described passive roller group includes passive roll shaft and with it by bonded passive roller;Described initiative roll shaft and driven roll Axle two ends are all erected on body by bearing block, and the axial line of described initiative roll shaft and passive roll shaft is with a plane and phase Mutually parallel；It is provided with groups of springs one between described active roller group and passive roller group, between passive roller group and frame, be provided with groups of springs two； Described groups of springs two connects to hold down gag.

Further, described initiative roll shaft and passive roll shaft is equivalently-sized；Described drive roll is identical with the size of driven roll.

Further, described groups of springs one includes two springs, is located at the bearing at initiative roll shaft and passive roll shaft two ends respectively Between seat, and it is connected with bearing block.

Further, described groups of springs two also includes two springs, is located at the bearing block at passive roll shaft two ends respectively, one End connects to bearing block, and the other end is connected with hold down gag.

Further, described hold down gag includes adjusting screw rod and pressure strip, and described adjusting screw rod is provided with two groups, connects respectively Two ends in pressure strip.

Further, described adjusting screw rod and the centrage of groups of springs two are with point-blank；Described adjusting screw rod also connects It is connected to regulation handle.

Further, state adjusting screw rod and be provided with size scale.

Further, described spring is spiral spring or air spring.

Further, described spring is replaced by can reach the same hydraulic cylinder mechanism compressing return effect.

When different size of material block is carried out with broken, driven roll can be squeezed existing disintegrating machine due to larger material block After pressure offsets to one side, because driven roll does not have direct drive unit to connect, its velocity of rotation leans on drive roll and broken thing block entirely Together drive, the driven roll rotating speed therefore in migration process has a certain impact, simultaneously also to whole crusher in crushing material block Crushing efficiency have considerable influence；And double-roll crusher of the present utility model, due to adopting said structure, by two rods Between be also provided with groups of springs so that groups of springs one and groups of springs two collective effect are it is achieved that driven roll moment autobalance rotating speed, Accelerate the regulation rhythm of disintegrating machine so that crusher in crushing efficiency uprises；And because groups of springs one is after receiving stretching, will Produce a return clamp force, such active force also increases the crushing force of disintegrating machine while making driven roll returning quickly, So that the material block that is broken is easier to be broken, improve the uniformity of broken material block, also improve the production effect of disintegrating machine Rate.

Due to adopting said structure, double-roll crusher of the present utility model can also be by adjustment compression dress to broken thing Material size be adjusted, adjusting screw rod is provided with size scale, this structure design it is ensured that two ends adjusting means adjust away from From being consistent；And because in actual use, spring has failed because of life-time service phase thrust, different springs plays deformation Situation is different, using two groups of adjusting screw rods, two groups of springs is adjusted respectively, also ensure that two groups of springs used in the later stage It is adjusted correspondingly because deformation is different in journey, improves the durability of spring mechanism, it is to avoid excessively frequently more Change spring assembly and cause using upper inconvenience.

In sum, due to employing technique scheme, the beneficial effects of the utility model are：

1st, this double-roll crusher structure is simple, workable.

2nd, pass through to be additionally arranged spring mechanism between two rollers it is achieved that disintegrating machine autobalance rotating speed, improve disintegrating machine Crushing efficiency.

3rd, the groups of springs structure set up makes the crushing force of disintegrating machine increase, and improves the uniformity of broken material.
