Description
Technical field
Jaw crusher the present invention relates to the swing jaw of jaw crusher and for being crushed stone material.
Background technique
Such as by 196 31 023 A1 of DE it is known that jaw crusher generally includes the first crushing jaw and the second crusher
Jaw, wherein in most cases, a crushing jaw is configured to static crushing jaw, and another crushing jaw constructs
To swing crushing jaw.Crushing jaw is for broken from firmly to stone material, such as lime stone or dolomite.The strength of materials
Cause especially to generate relatively high load on swinging jaw in jaw crusher.In order to bear to load, the usual structure of jaw is swung
Cause closed cast case, wherein for the angle of foundry engieering, multiple holes are set in cabinet, are cast to position and keep
Core.However, it has been found that in shattering process, since there is and cause swing jaw damage in higher power and stress, this
Some holes becomes weakness.
Summary of the invention
Therefore, the purpose of the present invention is to design swing jaw, wherein the stress generated in swinging jaw is reduced.
According to the present invention, which is realized by the feature of independent claims 1 and 12.
The swing jaw of jaw crusher according to the present invention has receiving component and supporting zone, and receiving component setting is being put
The top of dynamic jaw, to be used to broken jaw swingingly (pivotally) being retained on jaw crusher, and supporting zone is arranged in
The lower part of jaw is swung, to be used to support swing jaw, wherein in order to reinforce, swinging jaw has hollow body structure, and hollow body structure exists
At least one diamondoid unit cells is set on cross section.At least one cell to assume diamond in shape in cross section has diagonal line, should
Diagonal line is transversely to the machine direction central plane and extends and extend to the second side from the first side.Power is optimally distributed simultaneously as a result,
And stress is reduced.
Compared to the walf checks mode previously generallyd use, the advantages of diamond shape, is that power path can be well distributed, and
Thus the stress generated in hollow body structure can be reduced.In addition, very being resisted by least one diamondoid unit cells
Torsion structure so that need not will swing jaw again is configured to closed cast case, but can be configured to open wide in one or both sides.
The advantages of open type constructs, which also resides in, to be casting core dispensing orifice, thus avoid the known weak spot swung in jaw.
The shape of diamond shape is similar to the shape of the tree of growth, is properly termed as " bionical swing jaw ".Diamondoid unit cells are compared to China
Husband's lattice mode needs less quality, is maintained in lower range with dispersion force and by stress.In addition, save foreboard and/or
Back plate is but also the casting of component is very easy to.Further, since reinforcer/muscle accessibility, therefore may be easy to check each
The quality (chamber inspection) of a reinforcer.Further, since obtaining accessibility, therefore can be by other function (for example, with dividing
From crushing jaw installation possibility) be integrated into supporting structure.
Other advantage and embodiment of the invention is stated in the dependent claims.
According to preferred embodiment, hollow body structure at least extends from the receiving component for swingingly holding swing jaw
To supporting zone.In addition, hollow body structure on cross section include at least one diamondoid unit cells and triangular element lattice, thus
Hollow body structure extends to side.
Swinging jaw has the longitudinal median plane extended perpendicular to the pivot axis for swinging jaw, wherein the water chestnut on cross section
Shape cell is arranged so that longitudinal median plane forms the symmetrical plane of diamondoid unit cells.Thus cell medially arranges,
So as to so that generated power, torque and stress are well distributed.
According to other embodiment, at least two diamondoid unit cells, at least two diamondoid unit cells are set on cross section
It is disposed adjacent to one another in the angular zone of diamondoid unit cells, so that longitudinal median plane forms each of two diamondoid unit cells
A symmetrical plane.Swinging jaw has front side, rear side, the first side and the second side, and front side is used to that crushing jaw to be arranged,
In, hollow body structure can be structured as in front side and/or rear open.
The invention further relates to jaw is swung, with front side, rear side and two sides, wherein front side is provided with crushing jaw.
In this case, crushing jaw is supported in hollow body structure in the contact areas, wherein crushing jaw is in the contact area
In can have the reinforcement structure for being adapted to hollow body structure so that the dissipation of optimized force.
In order to reinforce the first side and the second side, lateral reinforcer can be equipped with.Furthermore, it is possible to which construction is swung in this way
Jaw, so that swinging jaw is tapered to support from the receiving component for swingingly holding swing jaw in a manner of wedge shape in side view
Region, so that weight reduces in lower area.
Furthermore, it is envisioned that the foreboard with hollow body structure one-piece construction is arranged on the front side for swinging jaw.This
Help extraly to reinforce swinging jaw.If such foreboard is arranged, preferred rear side is configured to open wide, and swings jaw to simplify
Manufacture.
The invention further relates to the jaw crusher for being crushed stone material, jaw crusher has the entrance for stone material, uses
In outlet, the first crushing jaw and the second crushing jaw of broken stone material, wherein at least one structure in two crushing jaws
It makes to swing crushing jaw, and at least one crushing jaw is fixed on swing jaw as characterized above.Another is broken
Machine jaw can be structured as static or swing.In the case where static structures, another crushing jaw is arranged in stationary support
On, wherein stationary support is also included within the hollow structure on cross section at least one diamondoid unit cells.
