Abstract
The utility model discloses a jaw crusher which comprises an upper rack, a lower rack, a side rack, a first fixed jaw plate, a first movable jaw plate, a four-bar mechanism, a second movable jaw plate and a second fixed jaw plate. A first crushing cavity is formed by the first fixed jaw plate and the first movable jaw plate; the four-bar mechanism consists of an eccentric shaft, connecting rods, a rocker rod, the upper rack and the lower rack; the first movable jaw plate and the second movable jaw plate are respectively arranged at both sides of connecting rods; the first movable jaw plate and the second movable jaw plate are respectively arranged opposite to the first fixed jaw plate and the second fixed jaw plate; and a second crushing cavity is formed by the second fixed jaw plate and the second movable jaw plate. The jaw crusher provided by the utility model is provided with two crushing cavities; the two crushing cavities can alternately work; the energy of a motor is sufficiently utilized; the production capacity is doubled; and the unit power is obviously reduced. Moreover, both fixed jaw plate seats are provided with knee plates, so that a machine body can be effectively prevented and the loss is reduced.
Description
Technical field
The utility model relates to the disintegrating apparatus technical field, is specifically related to a kind of jaw crusher.
Background technology
The unit power of formula disintegrating machine and production capacity are to weigh two leading indicators of overall performance, boost productivity, reduce unit power and once taked many measures, as: (1) changes support pattern, become just supporting and be negative supporting, improve characteristic value, the stroke of improving the standard has played the effect that improves production capacity; (2) crusher chamber is optimized, makes the coupling of feed and discharge reach optimum state, fully improve production capacity; (3) mechanism is optimized, a formula disintegrating machine is a kind of typical quadric chain, to the optimization of mechanism, makes the coupling of each rod member of disintegrating machine more reasonable, reaches best output characteristics, to improve production capacity etc.Although Adopts measure is a lot, but these improvement are very incomplete, the work characteristics of formula disintegrating machine is an impulse stroke (shattering process of material), a backstroke justice claims idle stroke (discharge process of material). backstroke is consumption of power, do not carry out again crushing operation: in existing formula crusher structure, it is unavoidably, also to be a process can't eliminating.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The utility model content
The purpose of this utility model is to provide a kind of two-chamber volume formula disintegrating machine of efficient, energy-conservation, no-idle running.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopts is: jaw crusher, comprise that upper spider, lower bearing bracket, side frame, first decide jaw, the first moving jaw plate and quadric chain, and first decides jaw and the first moving jaw plate forms the first crusher chamber; It is characterized in that: comprise that also the second moving jaw plate and second decides jaw; Described quadric chain is comprised of eccentric shaft, connecting rod, rocking bar and upper spider, lower bearing bracket, and described connecting rod lower end is hinged by eccentric shaft and lower bearing bracket, and an end of described small end and rocking bar is hinged, and the other end and the upper spider of described rocking bar are hinged; Described the first moving jaw plate and the second moving jaw plate are separately positioned on the both sides of connecting rod; Described the first moving jaw plate and the second moving jaw plate are relative respectively to be provided with first and to decide jaw and second and decide jaw, and described first decides jaw and second decides jaw and be arranged on the side frame by deciding the jaw seat respectively; Described the second moving jaw plate and second is decided jaw and is formed the second crusher chamber.
Described upper end and the side frame of deciding the jaw seat is hinged, and lower end and side frame are provided with bracket.
In sum, jaw crusher provided by the utility model has two crusher chamber.When one of them crusher chamber was in impulse stroke, another crusher chamber was in backstroke.When described eccentric shaft turned over certain angle, then the first crusher chamber was in backstroke, and the second crusher chamber is in impulse stroke.With this reciprocation cycle, the energy of motor is fully utilized, and production capacity is doubled, and unit power significantly descends.And two decide the jaw seat all is provided with bracket, can effectively protect body, reduces the loss.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the 1, first moving jaw plate; 2, first decides jaw; 3, connecting rod; 4, eccentric shaft; 5, rocking bar; 6, the second moving jaw plate; 7, second decides jaw; 8, decide the jaw seat; 9, bracket; 10, side frame; 11, the first crusher chamber; 12, the second crusher chamber.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
-as shown in Figure 1, this jaw crusher comprises that upper spider, lower bearing bracket, side frame 10, first decide jaw 1, the first moving jaw plate 2 and quadric chain, first decides jaw 1 and the first moving jaw plate 2 forms the first crusher chamber 11; It is characterized in that: comprise that also the second moving jaw plate 6 and second decides jaw 7; Described quadric chain is comprised of eccentric shaft 4, connecting rod 3, rocking bar 5 and upper spider, lower bearing bracket, and described connecting rod 3 lower ends are hinged by eccentric shaft 4 and lower bearing bracket, and an end of described connecting rod 3 upper ends and rocking bar 5 is hinged, and the other end and the upper spider of described rocking bar 5 are hinged; Described the first moving jaw plate 2 and the second moving jaw plate 6 are separately positioned on the both sides of connecting rod 3; Described the first moving jaw plate 2 and the second moving jaw plate 6 are relative respectively to be provided with first and to decide jaw 1 and second and decide jaw 7, and described first decides jaw 1 and second decides jaw 7 and be arranged on the side frame 10 by deciding jaw seat 8 respectively; Described the second moving jaw plate 6 and second is decided jaw 7 and is formed the second crusher chamber 12.
Described upper end and the side frame 10 of deciding jaw seat 8 is hinged, and lower end and side frame 10 are provided with bracket 9.Fragmentation is upper prescribes a time limit when material hardness surpasses, and bracket can rupture, with the protection body.
The utility model can be applicable to the field of the comminution process such as mine, metallurgy, electric power, building materials, chemical industry, traffic.
In sum, jaw crusher provided by the utility model has two crusher chamber.When one of them crusher chamber was in impulse stroke, another crusher chamber was in backstroke.When described eccentric shaft turned over certain angle, then the first crusher chamber was in backstroke, and the second crusher chamber is in impulse stroke.With this reciprocation cycle, the energy of motor is fully utilized, and production capacity is doubled, and unit power significantly descends.And two decide the jaw seat all is provided with bracket, can effectively protect body, reduces the loss.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
