Description

A kind of list jaw double-shaft mechanism crusher

Technical field

The utility model belongs to jaw crusher technical field more particularly to a kind of single jaw double-shaft mechanism crusher.

Background technique

Jaw crusher, is commonly called as that jaw is broken, and most popular currently on the market is single toggle jaw crusher, it by dynamic jaw and Determine two pieces of jaw composition crusher chambers of jaw, is the crusher simulated two jaw movements of animal and complete material crushing operation.Fortune extensively It is broken for the medium size of various ores and bulk materials in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry It is broken.

The jaw crusher (referring to single toggle jaw crusher, similarly hereinafter) of the prior art has a common allusion quotation in terms of amechanical angle Type structure all moves jaw with crank and rocker mechanism (its eccentric drive shaft is crank, and dynamic jaw is connecting rod, and bracket is rocking bar) Side and machine fixed jaw side form a broken discharge chamber, and dynamic jaw top directly leans on eccentric drive shaft to obtain horizontal direction Broken stroke, dynamic jaw lower part circle the broken stroke and discharges material that drive bracket to wave acquisition horizontal direction by moving jaw Stroke.

It is well known that jaw crusher on the market, crumbling method are bent dynamic extrusion pressing type at present, power device drives dynamic Jaw makes jaw move up and down by driving wheel or eccentric shaft, and when dynamic jaw rises, angle becomes larger between bracket and dynamic jaw, to push Moving jaw plate is close to jaw is determined, and material such as is extruded, rubs with the hands, grinding at multiple be crushed at the same time；When dynamic jaw downlink, bracket and dynamic jaw Between angle become smaller, moving jaw plate leaves under the action of pull-rod spring determines jaw, at this time broken material under crusher chamber mouth be discharged, Make periodically crushing and discharge as the continuous rotation of power device is crushed motor-driven jaw, realizes batch production, however in reality In work, the crushing function of jaw crusher on the market is mainly reflected in the middle and upper part of crusher chamber, and its underpart is absolutely not broken Broken function only has the function of discharge, for another example: Chinese patent 201110092031.0 is introduced " a kind of to have twin shaft hyperbolic The jaw crusher of handle rocker device " moves under jaw before changing with the combination of one in front and one in back two sets of crank and rocker mechanisms The effect of mechanical structure in portion, change subtracts power as reinforcement, a crusher is made to be provided with two-stage crushing, improves reduction ratio, and Preceding dynamic jaw has been become into broken and discharge dual function from single discharge function, but this kind of structure need to increase by one it is driven Jaw and a set of crank and rocker mechanism can realize said effect, and need to be provided with spring reverse motion.

In conclusion of the existing technology in order to solve the problems, such as, it is urgent to provide a kind of single jaw double-shaft mechanism is broken at present Machine can achieve the broken purpose of a machine two, not only can be omitted a set of crank and rocker mechanism and spring reverse motion, effectively Crusher energy consumption is saved, and dynamic jaw assembly whole can do work and realize crusher double-cavity crushing, it can also be simultaneously to dynamic jaw The sufficient sealing lubrication of assembly.

Utility model content

The utility model proposes a kind of single jaw double-shaft mechanism crushers, by the way that an eccentric shaft is arranged in dynamic jaw assembly lower part A machine two is also able to achieve while existing crusher Conventional mechanisms can be simplified with sliding block broken, the effective solution prior art is deposited The problem of.

In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
