Description
Technical field
The utility model belongs to crusher jaw technical field, and in particular to a kind of jaw crusher jaw.
Background technique
Jaw, also referred to as tooth plate, the be broken cross section of working portion of material contact You Qiyu is similar oral cavity or more
The tooth of jaw and gain the name.The working portion of usual jaw crusher is two pieces of jaws, first is that fixed jaw, is mounted on body antetheca
On, another is sewing jaw, is mounted on dynamic jaw.Sewing jaw and fixed jaw form up big and down small crusher chamber.Jaw
The ore size granularity of the upper, middle and lower contact of tooth is different, and the effect played in shattering process is not also identical,
Therefore, in use for some time, upper, middle and lower abrasion loss is not also identical.Under normal conditions, the tooth mill of jaw lower part
Damage faster.Generally before the tooth of lower part is smoothed, the lower part of jaw and top are carried out u-turn use, to make monolith jaw
Plate tooth surface abrasion is uniform, increases operation rate.In the shattering process to ore, fixed jaw is stationary, and movable jaw
Plate does periodic reciprocating motion against fixed jaw, and therefore, the speed that they wear is not also identical.Fixed jaw wears more
Fastly, the amount ratio of general fixed jaw and sewing jaw is about 2:1, i.e., two pieces of fixed jaws are finished, and correspondence is finished one piece of work
Moving jaw plate.So the warehouse inventory of fixed jaw and sewing jaw is not also identical, fixed jaw is more, and quantity is usually
Twice of sewing jaw.Since the jaw of the prior art is straight strip from top to bottom from longitudinal see, also often will appear in this way
One problem: when encountering the very big ore of hardness, causing ore to upspring due to not being crushed, and can produce in the middle part of jaw
Raw " spitting material " phenomenon often said.At this moment, after generally requiring repeatedly " spitting material " several times, ore reduction could be fallen.To make ore
Extended by the time of crusher chamber, the broken processing capacity decline of jaw causes yield to reduce, and increase power consumption and abrasion.
The arrangement from top to lower part of existing jaw tooth is unreasonable, is easy to appear phenomena such as spitting material when in use, and
Jaw needs to produce the jaws of two pieces of different structures when producing, cause the raising of production cost, and jaw jaw when in use
It is easy to appear and gets stuck at bottom of the tooth, during jaw crusher work, broken if there is the higher ore materials of water content enter
When broken intracavitary, the material containing moisture is broken into fritter by crusher, at this moment due to containing moisture in material, is had certain
Viscosity, and broken material is easy to be caught in the problem of bottom of the tooth formation gets stuck, thus it is proposed that a kind of jaw crusher is used
Jaw.
Utility model content
The purpose of this utility model is to provide a kind of jaw crusher jaws, to solve to propose in above-mentioned background technique
Existing jaw tooth the arrangement from top to lower part it is unreasonable, be easy to appear phenomena such as spitting material when in use, and jaw is raw
The jaw for needing to produce two pieces of different structures when production, causes the raising of production cost, and jaw is when in use at the bottom of the tooth of jaw
It is easy to appear and gets stuck, during jaw crusher work, if there is the higher ore materials of water content enter in crusher chamber
When, the material containing moisture is broken into fritter by crusher, at this moment due to containing moisture in material, has certain glue
Degree, and broken material is easy to be caught in the problem of bottom of the tooth formation gets stuck.
To achieve the above object, the utility model provides the following technical solutions: a kind of jaw crusher jaw, including jaw
Plate main body, the inside of the jaw offer groove, and the inside of the groove is installed with stressed plate, the bottom of the stressed plate
Portion is installed with spring, is installed with top pillar at the top of the stressed plate.
Preferably, the longitudinal direction of the jaw main body is divided into three parts from top to bottom: upper, middle and lower, top, middle part
Identical with the cross-sectional shape of the tooth of lower part, the middle part tilts an angle and top is connected with supermedial tooth, makes top
On tooth top center line and lower part bottom of the tooth center line on same parallel lines.
Preferably, in the middle part of the top and lower part is an integral structure.
Preferably, one end of the spring is installed in the bottom of stressed plate, and the other end of the spring is installed in groove
Surface.
Preferably, the surface of the jaw main body offers limit hole, and the top pillar is installed in limit hole.
Preferably, the middle part inclination is installed between top and lower part.
Preferably, top pillar is installed on the upper, middle and lower.
Compared with prior art, the utility model has the beneficial effects that
(1) offer on a rare occasion a groove in the inside of the jaw, be installed in groove by spring connect by
One end of power plate, stressed plate is installed with top pillar, and when jaw is in broken material, the phenomenon that gets stuck occurs in the bottom of the tooth of jaw, in jaw
The top pillar ejection that can will get stuck avoids the occurrence of jaw and gets stuck phenomenon during the material returned of periodic motion repeatedly, improves the reality of the jaw
The property used；
(2) tooth of the jaw is rearranged from top to bottom, top tooth top center line is overlapped with lower teeth bottom center line
On same parallel lines, be kept fixed jaw it is opposite with bottom of the tooth with sewing jaw tooth top under conditions of, make fixed jaw and work
Moving jaw plate is identical, and two kinds of jaws become a kind of jaw, can both be used as fixed jaw, can also be used as sewing jaw, together
When also avoid the fixed jaw problem opposite with tooth top with sewing jaw tooth top, to reduce manufacturing cost and use cost；
(3) jaw, so popping up certain inhibition to ore, can subtract since center teeth is inclined
Slow " spitting material " problem improves yield to improve the processing capacity in the big ore of broken hardness.
