Technical field

The present invention relates to a kind of jaw crusher rocker structures.

Background technique

Operating mechanism's habit of single toggle jaw crusher is known as four-bar mechanism, is successively connected by crank, connecting rod, rocking bar, rack Connect composition.Wherein, rocking bar and coupling for connecting rod are skid moving-wire contact structures, and rocking bar is also that skid moving-wire connects with coupling for rack Touch structure.The crank and rocker mechanism being made of skid moving-wire contact connection during the work time length of connecting rod will appear it is uncontrollable Random fluctuation, rack length also will appear uncontrollable random fluctuation.So this crank and rocker mechanism is strictly a kind of Become the long four-bar mechanism of bar, this change long four-bar mechanism of bar can have an impact the kinetic characteristic of connecting rod, i.e., to tooth plate horizontal line The influence of journey and characteristic value.The horizontal throw and characteristic value of tooth plate are to the crushing efficiency of jaw crusher, the granularity of crushed product The performance indicators quite sensitives such as distribution, tooth plate abrasion and energy consumption, therefore this long four-bar mechanism of bar that becomes will cause jaw Crusher overall performance is unstable, i.e. reliability decrease and Key Performance Indicator deterioration.

Summary of the invention

Goal of the invention of the invention is to provide a kind of jaw crusher rocker structure, and overall performance stabilization is effectively ensured can It leans on.

Realize the object of the invention technical solution:

A kind of jaw crusher rocker structure, it is characterised in that: rocking bar one end and rack are hinged, described hinged two-way by first Coupling structure is rotated to realize；The rocking bar other end and connecting rod are hinged, described hingedly to be realized by the second Double-directional rotary coupling structure.

Further, the Double-directional rotary coupling structure is to couple to be equipped with articulated shaft on pedestal, is set on articulated shaft Link arm, link arm can be with respect to articulated shaft Double-directional rotaries.

Further, in the first Double-directional rotary coupling structure, connection pedestal is fixed with rack, link arm and rocking bar one End is fixed；In the second Double-directional rotary coupling structure, connection pedestal is fixed with connecting rod, and link arm is fixed with the rocking bar other end.

Further, 1,2 or multiple first Double-directional rotary coupling structures are equipped between rocking bar and rack.

Further, 1,2 or multiple second Double-directional rotary coupling structures are equipped between rocking bar and connecting rod.

Further, Double-directional rotary coupling structure is equipped with 1 connection pedestal, 2 connection pedestals or multiple connection pedestals.

Further, Double-directional rotary coupling structure and the connection type of rack, rocking bar, connecting rod are that integrally formed, welding connects It connects, connection or screw, bolt, rivet interlacement are inlayed in interference.

The utility model has the advantages that

Rocking bar one end of the present invention and rack are hinged, described hingedly to be realized by the first Double-directional rotary coupling structure；The rocking bar other end It is hinged with connecting rod, it is described hingedly to be realized by the second Double-directional rotary coupling structure.Due to rocking bar of the present invention and rack, rocking bar and company Coupling structure between bar is Double-directional rotary coupling structure, and coupling structure is only capable of Double-directional rotary, skid linear movement will not occur, To guarantee that the four-bar mechanism of jaw crusher is fixed length four-bar mechanism, overall performance stability and reliability is effectively ensured.This Invention can meet the passing movement requirement and bearing requirements of different model and different size jaw crusher, and structure of the invention can The uniqueness for ensureing specified point characteristic value on dynamic jaw tooth plate gives the uniqueness of overall performance index under operating condition, and is four bar machines The foundation of structure analytic modell analytical model provides theoretical basis.Structure of the invention is reasonable, widely applicable, can effective guarantee jaw crusher it is whole The stability and reliability of machine performance, the foundation for four-bar mechanism analytic modell analytical model provide theoretical basis, to jaw crushing mechanism Improving for opinion is of great significance with development.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of invention jaw crusher rocker structure.

Specific embodiment

As shown in Figure 1,4 one end of rocking bar and rack 1 are hinged, it is described hingedly to be realized by the first Double-directional rotary coupling structure； 4 other end of rocking bar and connecting rod 5 are hinged, described hingedly to be realized by the second Double-directional rotary coupling structure, 5 other end of connecting rod and crank Hingedly.

The Double-directional rotary coupling structure is to couple to be equipped with articulated shaft 3 on pedestal 2, is set with link arm on articulated shaft 3 6, link arm 6 (can be rotated counterclockwise and be rotated clockwise with respect to 3 Double-directional rotary of articulated shaft.The first Double-directional rotary connection knot In structure, connection pedestal and rack 1 are fixed, and link arm is fixed with 4 one end of rocking bar；In the second Double-directional rotary coupling structure, connection Joint chair body and connecting rod 5 are fixed, and link arm is fixed with 4 other end of rocking bar.

It is equipped with 1,2 or multiple first Double-directional rotary coupling structures between rocking bar 4 and rack 1, in the present embodiment, is equipped with 5 the first Double-directional rotary coupling structures.1,2 is equipped between rocking bar 4 and connecting rod 5 or multiple second Double-directional rotaries couple knot Structure in the present embodiment, is equipped with 5 the second Double-directional rotary coupling structures.

Double-directional rotary coupling structure is equipped with 1 connection pedestal, 2 connection pedestals or multiple connection pedestals.In the present embodiment, Using 2 connection pedestals.

Double-directional rotary coupling structure and the connection type of rack, rocking bar, connecting rod are integrally formed, welded connecting, interference edge Embedding connection or screw, bolt, rivet interlacement.In the present embodiment, using welding connecting mode.

Above in conjunction with attached drawing, an exemplary description of the invention, it is clear that realization of the invention is not by aforesaid way Limitation, as long as use the inventive concept and technical scheme of the present invention carry out various improvement, or it is not improved will be of the invention Conception and technical scheme directly apply to other occasions, be within the scope of the invention.
