Abstract
The utility model discloses a kind of toothed plate of jaw crusher, comprise tooth plate body, described tooth plate body upper surface arranges crushing teeth arranged in a uniform, and crushing teeth is divided into upper, middle and lower, and described upper and lower is parallel staggers and is connected to form " Z " font by the middle part tilted." Z " font crushing teeth of the utility model toothed plate of jaw crusher can make material, in dropping process, lateral displacement occur, add the transverse shear stresses to material, change the stressing conditions of material, more easily can process sheet material, reduce the generation of the material of unreasonable particle shape, product granularity composition and particle shape more can be met the demands, and material fragmentation in crusher chamber is more abundant, percentage of damage is higher, and output is also higher.
Description
Technical field
Embodiment of the present utility model relates to component of machine, and more specifically, embodiment of the present utility model relates to a kind of toothed plate of jaw crusher.
Background technology
Although toothed plate structure is simple, but it all has a great impact the productivity ratio of jaw crusher, observable index, raw meal particle size composition and particle shape and crushing force etc., existing tooth plate cross-sectional structure shape has smooth surface and toothed surfaces two kinds, profile of tooth is mainly divided into triangle and trapezoidal two kinds, tooth bar becomes the arrangement of " 1 " font, cannot produce the transverse shear stresses to material, in use, material cannot be broken fully, easily produces sheet material.The generation of sheet material can increase the concentrated wear of tooth plate, thus reduces the service life of tooth plate, and under identical power, the output of certified products will reduce, thus adds operating cost.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, provides a kind of embodiment of toothed plate of jaw crusher, by changing the structure of tooth bar, makes it produce lateral stress to material, thus fully broken, reduces concentrated wear, increase yield.
For solving above-mentioned technical problem, a kind of embodiment of the present utility model by the following technical solutions:
A kind of toothed plate of jaw crusher, comprise tooth plate body, described tooth plate body upper surface arranges crushing teeth arranged in a uniform, and described crushing teeth is divided into upper, middle and lower, and described upper and lower is parallel staggers and is connected to form " Z " font by the middle part tilted.
Further technical scheme is: the angle of the junction at described top and middle part is 90 degree ~ 180 degree, and the angle of the junction at described bottom and middle part is 90 degree ~ 180 degree.
Further technical scheme is: the angle of the junction at described top and middle part is 120 degree ~ 150 degree, and the angle of the junction at described bottom and middle part is 120 degree ~ 150 degree.
Further technical scheme is: described upper, middle and lower is bar shaped.
Further technical scheme is: the lower surface of described tooth plate body all has lightening hole, and described lightening hole is positioned at immediately below crushing teeth.
Further technical scheme is: the spacing between two adjacent crushing teeths is 30 ~ 35mm.
Compared with prior art, one of the beneficial effects of the utility model are: the utility model toothed plate of jaw crusher " Z " font crushing teeth can make material, in dropping process, lateral displacement occur, add the transverse shear stresses to material, change the stressing conditions of material, more easily can process sheet material, reduce the generation of the material of unreasonable particle shape, product granularity composition and particle shape more can be met the demands, and material fragmentation in crusher chamber is more abundant, percentage of damage is higher, and output is also higher.

Fig. 1 is the front view of the utility model toothed plate of jaw crusher.
Fig. 2 is the C-C sectional view of Fig. 1.
Fig. 3 is the rearview of the utility model toothed plate of jaw crusher.
Fig. 4 is the B-B sectional view of Fig. 1.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, toothed plate of jaw crusher, formed by multiple crushing teeth 100 is evenly distributed, crushing teeth 100 comprises the top 101 of bar shaped, the middle part 102 of bar shaped and the bottom 103 of bar shaped, top 101 is parallel with bottom 103 staggers, and being connected to form " Z " font by the middle part 102 tilted, the angle between top 101 and middle part 102, between 90 ~ 180 degree, preferably uses 120 ~ 150 degree, angle between bottom 103 and middle part 102 also can be 90 ~ 180 degree, is preferably 120 ~ 150 degree.As shown in Figure 2,3, 4, toothed plate of jaw crusher is provided with multiple lightening hole 104, and lightening hole 104 is positioned at immediately below crushing teeth 100, for alleviating the weight of tooth plate.Preferably, the spacing between two adjacent crushing teeths 100 is between 30 ~ 35mm.
This tooth plate adopts unique Curve guide impeller on full depth tooth plate base." Z " font profile of tooth in the middle part of tooth plate, make material, in dropping process, lateral displacement occur, add the transverse shear stresses to material, change the stressing conditions of material, more easily can process sheet shape material, reduce the material of unreasonable particle shape, product granularity composition and particle shape more can be met the demands.Due to stressed change, material fragmentation in crusher chamber is more abundant, and percentage of damage is higher, and output is also higher.
Although be described the utility model with reference to multiple explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
