Abstract
The utility model discloses a kind of gyratory crusher two-component crushing wall, including crushing wall top, and the crushing wall lower part being connect with crushing wall top, and the crushing wall top is potassium steel, and the crushing wall lower part is high-carbon chromium steel；Crushing wall top lower end is provided with installation protrusion, and crushing wall lower part upper end is provided with the installation groove with the raised phase clamping cooperation of installation, bolt is provided between the installation protrusion and installation groove.Since the crushing wall top is potassium steel, the crushing wall lower part is high-carbon chromium steel, homogenous material crushing wall is fundamentally solved during broken building stones, since the building stones of different size are different to the wear extent of crushing wall, building stones breaking cavity can not be crushed the critical defect of building stones at groove caused by caused crushing wall Upper wear is small, lower part abrasion is big；The setting of additionally mounted protrusion and installation groove so that replace crushing wall top or crushing wall lower part is all more convenient, and this connection type is more secured.
Description
Technical field
The utility model is related to a kind of gyratory crusher two-component crushing walls.
Background technology
Gyratory crusher during broken building stones from oversize rock material it is broken to be crushed to fritter building stones is two kinds of differences
Working condition, for being crushed oversize rock material, what oversize rock material formed rolled mortar wall top is impact load on crushing wall top
Lotus, and building stones and crushing wall formed be do not know, the impact extruded that is not all of contact coordinates, thus on crushing wall
The state of wear in portion is relatively small；And to be rubble roll manufacture chamber for crushing wall lower part, broken small building stones and crushing wall formed plyability,
The rubble of full contact property, under the small strength in crushing wall of broken gravelstone between crushing wall squeezes, broken small building stones are to broken
The abrasion of broken wall is extremely serious.If making crushing wall, either potassium steel or rich chromium cast iron using homogenous material is adopted, by
It is different to the wear extent of rolled mortar wall in the building stones of different size, as a result cause crushing wall Upper wear is small, in the abrasion relatively of middle part
Portion is small and the situation to form groove is worn in lower part, and rolled mortar wall and crushing wall is caused to wear, and blanking velocity is slow, and machine electric current increases
Greatly, crushing wall is replaced in instruction, and crushing wall service life is short.
Utility model content
The purpose of this utility model, which is to provide, a kind of can greatly improve the double groups of its wearability and persistent gyratory crusher
Part crushing wall.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of gyratory crusher two-component crushing wall, including crushing wall top, and the crushing wall that is connect with crushing wall top
Lower part, the crushing wall top are potassium steel, and the crushing wall lower part is high-carbon chromium steel；Crushing wall top lower end is provided with
Installation protrusion, crushing wall lower part upper end are provided with the installation groove with the raised phase clamping cooperation of installation, the installation protrusion
Bolt is provided between installation groove.
Preferably, the crushing wall top is both provided with the arc groove of one or more, arc groove is from top to down in a ring
Display is arranged, and inlays more than one salient point in the arc groove.
Preferably, the salient point is high-carbon chromium steel salient point.
Preferably, crushing wall lower part is internally provided with reinforcing rib structure.
Preferably, the reinforcing rib structure includes cross reinforcing and waling, and cross reinforcing and longitudinal direction
Reinforcing rib in net distribution within the outer shell.
The utility model has the beneficial effects that：Since the crushing wall top is potassium steel, the crushing wall lower part is height
Carbon chromium steel fundamentally solves homogenous material crushing wall during broken building stones, since the building stones of different size are to broken
The wear extent of wall is different, and building stones breaking cavity is at groove caused by caused crushing wall Upper wear is small, lower part abrasion is big
And the critical defect of building stones can not be crushed；The setting of additionally mounted protrusion and installation groove so that replace crushing wall top or broken
Broken wall lower part is all more convenient, and this connection type is more secured.
Description of the drawings
Fig. 1 is the schematic diagram of the gyratory crusher two-component crushing wall of the utility model.
Specific implementation mode
In the present embodiment, it should be noted that relational terms such as first and second and the like are used merely to one
A entity or operation with another entity or operate distinguish, without necessarily requiring or implying these entities or operation it
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant are intended to
Cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those
Element, but also include other elements that are not explicitly listed, or further include for this process, method, article or setting
Standby intrinsic element.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, connection or solid
Determine mode can be fixed by bolt commonly used in the prior art or pin fix or axis pin connection etc. modes, therefore, this
It is no longer described in detail in embodiment.
As shown in fig.1, a kind of gyratory crusher two-component crushing wall, including crushing wall top 1, and with crushing wall top
The crushing wall lower part 2 of 1 connection, the crushing wall top 1 are potassium steel, and the crushing wall lower part 2 is high-carbon chromium steel；It is described broken
1 lower end of wall top is provided with installation protrusion 10, and 2 upper end of crushing wall lower part is provided with and the raised 10 phase clampings cooperation of installation
Installation groove 11 is provided with bolt (not shown) between installation protrusion 10 and installation groove 11, by installation groove 11 with
The clamping cooperation of installation protrusion 10, along with bolt is fixed so that be connected firmly, while replacing again conveniently.
The crushing wall top 1 is both provided with the arc groove 12 of one or more, and arc groove 12 displays in a ring from top to down
It is arranged, inlays more than one salient point 13 in the arc groove 12.The salient point 13 is high-carbon chromium steel salient point.It can by salient point 13
To reduce the contact area of material and crushing wall top 1, to slow down the abrasion for determining liner plate.Simultaneously because on contact crushing wall
The material in portion 1 is larger, and by bump contacts, better crushing effect can be reached.
Crushing wall lower part 2 is internally provided with reinforcing rib structure, and reinforcing rib structure can enhance the flexibility of crushing wall, can
Preferably crushing wall to be avoided to be damaged, extend the service life of crushing wall, often crushing wall need not be repaired or
Person replaces, and can improve working efficiency, reduce cost.The reinforcing rib structure includes cross reinforcing 20 and waling
21, and cross reinforcing 20 and waling 21 in net distribution in the inside of crushing wall lower part 2, can increase in each orientation
The flexibility for adding crushing wall avoids crushing wall from occurring deforming or be broken, to extend the service life of crushing wall.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
