Description
Technical field
The utility model belongs to dynamic jaw assembly technical field, more particularly to a kind of three axis move jaw assembly.
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, at present it is urgent to provide a kind of three axis move jaw assembly can be with
Realize that dynamic jaw can move up and down and form an increasing to dynamic jaw lower part by the movement of the second eccentric shaft of lower part and concentric shafts
To increase the impact force of dynamic jaw lower part, which applies to not only can be omitted crank rocker in jaw crusher power
Mechanism and spring reverse motion can effectively save the energy consumption of crusher, and the dynamic jaw assembly can expand crusher
Whole acting is realized for double-cavity crushing.
