Abstract
The utility model relates to a jaw crusher with new structure, which is an improvement to the simple pendulum type and the double pendulum type jaw crushers and is suitable to be used in the machine with a wide crushing chamber. The crusher adopts eccentric shaft structure which is composed of a plurality of moving jaws and a plurality of eccentric poles, and each moving jaw is used for crushing the material respectively when the jaw crusher runs. Using the jaw crusher can greatly relieve the weight and the cost of the machine, and the utility model has the advantages of energy saving, easy starting process, smooth operation, etc.
Description
The utility model is a kind of Jaw formula disintegrating machine, is applicable to departments such as metallurgy, building materials, chemical industry, building, is particularly suitable for use in the operating mode occasion that needs Jaw formula crusher in crushing chamber broad, as the Jaw formula disintegrating machine of using on the cement industry in small, broken bits.
Prior art can be referring to " manufacture of cement plant equipment " P12～P25 of China Construction Industry Press's publication in 1981.As everyone knows, Jaw formula disintegrating machine is a kind of most popular crushing mechanism, and it is made up of support component, eccentric shaft parts and moving Jaw parts etc.Jaw formula disintegrating machine by the effect of biasing post on the eccentric shaft, makes Jaw do periodic reciprocation cycle motion to deciding Jaw when work, the time and close, the time and leave, when near the time, material between the two Jaw plates is crushed, and when leaving, crushed material draws off under the gravity effect automatically.Existing Jaw formula disintegrating machine can be divided into simple swing and two kinds of complicated swings according to the form of moving Jaw motion, and they all have only a moving Jaw and an eccentric shaft, are shaped on a biasing post on eccentric shaft.The eccentric shaft revolution moves a week, and this biasing post is finished Jaw once to crush material and unloaded the motion of material.When moving Jaw is in the stroke of crushing material, machine is subjected to maximum spike load effect, and is in the stroke of discharging as moving Jaw, and machine only is subjected to the inertia force effect of itself.The size of the shock loading that Jaw formula disintegrating machine is suffered and the width of moving Jaw are that the width of crusher chamber is directly proportional, and when the crusher chamber broad, this shock loading is bigger.The parts of Jaw formula disintegrating machine must be able to bear maximum impact loading during design, thereby each parts must be sufficiently large, and because eccentric shaft moving Jaw in the process of rotating a circle only finishes the one action circulation, so machine must be equipped with enough big flywheel and belt pulley with balanced power, thereby machine weight is bigger, cost is higher, the parts heaviness, and maintenance is inconvenient.And complete machine all is in more serious eccentric state in the starting and the course of work, thereby starting difficulty, the power consumption height, and swing is big, galloping.
Task of the present utility model provides a kind of novel Jaw formula disintegrating machine, it has less rotary inertia and inertia force, shock loading is less and balanced, and it is light to have machine weight, cost is low, easily starting, easy care, it is more steady to turn round, and the basis is required the characteristics of low and energy efficient.Also suitable to simultaneously existing physical pendulum formula and the transformation of tube pendulum-type Jaw formula disintegrating machine.
The utility model is that the load equalization principle according to dynamic (dynamical) equilibrium principle and machine designs.The rigid body of a rotation, when turning cylinder when barycenter is nearer, rotary inertia is less, inertia force is also less, when turning cylinder when barycenter is far away, rotary inertia is bigger, inertia force is also bigger, and when suffered outer year of machine evenly the time, the stress of machine and behavior in service are all better.According to this principle, the utility model replaces on common Jaw formula disintegrating machine and has only the eccentric shaft of a biasing post to design a kind of new-type eccentric shaft, this eccentric shaft has designed several biasing posts in the longitudinal direction successively, each biasing post has different eccentric directions with respect to eccentric shaft, and, usually each biasing post axial line is designed to have rotational symmetry preferably around eccentric shaft axis, makes the rotary inertia with respect to eccentric shaft be minimum, inertia force is also less.Belt pulley drives the eccentric shaft rotation during use, make each biasing post make garden Zhou Yundong with respect to the axle center of eccentric shaft, each biasing post directly makes suspension moving Jaw thereon and moving Jaw liner plate to deciding Jaw liner plate reciprocating (physical pendulum formula) by bearing again, perhaps each biasing post makes suspension link motion thereon by bearing again, and by the motion of connecting rod promotion thrust plate, thrust plate makes the moving Jaw that is suspended on the hanging scroll at last and moves the Jaw liner plate to deciding Jaw liner plate reciprocating (simple pendulum-type).Each biasing post and a moving Jaw interrelate, and be independent mutually between the moving Jaw, is arranged in order.Along with the rotation of eccentric shaft, each biasing post drives corresponding moving Jaw and moves the Jaw liner plate reciprocating to deciding the Jaw liner plate successively, thereby reaches the purpose of broken material.
Use the utlity model has following obvious advantage: at first, owing to adopted the structure of a plurality of moving Jaw and a plurality of biasing posts, rotate in all processes at eccentric shaft, each moving Jaw is once reciprocating to deciding the Jaw liner plate respectively, the suffered shock loading of machine is followed successively by the shock loading of each moving Jaw when working alone, thereby it is more much smaller than the shock loading of existing single action Jaw disintegrating machine, make intensity to the parts of machine, rigidity requirement reduces, help reducing the weight of machine, particularly use a plurality of moving Jaw and moving Jaw liner plate to make the single-piece weight saving of machine, give processing, make, installation and maintenance provide convenience.Secondly, owing to adopt the eccentric direction of a plurality of biasing posts on plane, to have rotational symmetry perpendicular to eccentric shaft, make eccentric shaft have the comparatively equilibrium of inertia force of less rotary inertia and machine itself, thereby can reduce moment of flywheel, and then can reduce the weight and the cost of machine greatly, and can bring to make machine start easily, turn round steadily, the basis is required to reduce and reduce idle power consumption, help motor-driven effect.In addition, owing between every moving Jaw mutual motion is arranged, help the disintegrating machine discharging, so output is also suitably improved.
Most preferred embodiment of the present utility model can provide in conjunction with the following drawings:
Fig. 1 is an eccentric shaft schematic diagram of the present utility model
Fig. 2 is the A-A cross-sectional schematic of Fig. 1
Fig. 3 is a physical pendulum formula Jaw formula crusher structure schematic diagram of the present utility model.
Fig. 4 is a simple pendulum-type Jaw formula crusher structure schematic diagram of the present utility model.
Transformation forms the utility model to common Jaw formula disintegrating machine.Replace on the eccentric shaft of existing Jaw formula disintegrating machine and only design single biasing post, designed a kind of novel eccentric shaft, this eccentric shaft has designed several biasing posts in the longitudinal direction successively, and each biasing post has different eccentric directions with respect to eccentric shaft.Be connected firmly for making between the adjacent biasing post, design has transition region (shaft shoulder) between the adjacent biasing post, and Fig. 1 and Fig. 2 have provided the eccentric shaft structure that two biasing posts are arranged, and this eccentric shaft structure is most appropriate to the transformation to existing Jaw formula disintegrating machine.The zone line of Fig. 1 is transition region (shaft shoulder), is biasing post, bearings mounted axle journal and taper shaft extension that flywheel or belt pulley are installed to both sides successively.Hatching shown in Figure 2 has partly been represented a biasing post, and dotted line has partly been represented the profile of another biasing post.
