The technical field is as follows:
the utility model relates to an iron ore field, concretely relates to hydraulic pressure gyratory crusher is used in iron ore exploitation.
Background art:
the iron ore refers to a mineral aggregate containing iron elements or iron compounds and capable of being economically utilized, and natural iron ore is gradually selected to be iron through procedures of crushing, grinding, magnetic separation, flotation, gravity separation and the like, wherein the crushing and grinding processes are most important in the mining technology of the iron ore, the iron ore is crushed by a hydraulic gyratory crusher in the prior art, but the space at the lower part of a crushing cavity formed between a movable cone and a static cone of the gyratory crusher is smaller during crushing, the lower part of the movable cone is subjected to higher stress and is easily abraded during extrusion operation of the movable cone and the static cone, the service life of the movable cone is greatly reduced, the movable cone needs to be integrally replaced during replacement, the production efficiency is influenced, and the waste of resources is easily caused.
The utility model has the following contents:
an object of the utility model is to provide a hydraulic pressure gyratory crusher is adopted in iron ore exploitation.
The utility model discloses by following technical scheme implement:
the utility model provides an iron ore mining is with hydraulic pressure gyratory crusher, includes the awl body that moves of breaker, it sets up ring groove to move awl body lower part, the lower taper sleeve that has cup jointed and has formed an organic whole with moving the awl body in the ring groove, the even division of taper sleeve outer wall has a plurality of T-arrangement groove down, the T-arrangement inslot joint has T shape extrusion piece, the bottom of moving the awl body is fixed with the pressure disk of taper sleeve under the restriction.
Preferably, the T-shaped extrusion block is composed of a fixture block and an extrusion block which are integrally formed, the fixture block is clamped in the T-shaped groove, and the extrusion block extends to the outer portion of the lower taper sleeve.
Preferably, the top of the T-shaped groove is communicated with the annular clamping groove.
Preferably, the bottom of the movable cone body is provided with a plurality of threaded holes, and the pressure plate is fixed with the threaded holes at the lower part of the movable cone body through a plurality of bolts in a threaded manner.
Preferably, the extrusion block is made of 65 Mn.
The utility model has the advantages that: this practicality sets up down the taper sleeve through the awl lower part that will revolve the breaker to set up the longer T shape extrusion piece in life-span in the taper sleeve outside down, can effectual assurance move the life of awl, it is comparatively convenient when maintaining to move the awl, need not whole change and practiced thrift the resource greatly, improve production efficiency, economic nature is higher.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a perspective view of the structure of the present invention;
fig. 2 is a schematic view of a first state of the present invention;
FIG. 3 is a schematic view of a second state of the present invention;
FIG. 4 is a schematic cross-sectional view of a T-shaped extrusion block of the present invention;
fig. 5 is a schematic diagram of the conventional structure of the present invention.
In the figure: the movable cone comprises a movable cone body 1, an annular clamping groove 2, a lower cone sleeve 3, a T-shaped groove 4, a T-shaped extrusion block 5, a fixture block 51, an extrusion block 52, a threaded hole 6, a pressure plate 7 and a bolt 8.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, a hydraulic gyratory crusher for iron ore mining comprises a movable cone body 1 of the crusher, an annular clamping groove 2 is arranged at the lower part of the movable cone body 1, a lower cone sleeve 3 integrated with the movable cone body 1 is sleeved in the annular clamping groove 2, a plurality of T-shaped grooves 4 are uniformly formed in the outer wall of the lower cone sleeve 3, T-shaped extrusion blocks 5 are clamped in the T-shaped grooves 4, and a pressure plate 7 for limiting the lower cone sleeve 3 is fixed at the bottom of the movable cone body 1.
The T-shaped extrusion block 5 is composed of a fixture block 51 and an extrusion block 52 which are integrally formed, the fixture block 51 is clamped in the T-shaped groove 4, and the extrusion block 52 extends to the outside of the lower taper sleeve 3.
The top of the T-shaped groove 4 is communicated with the annular clamping groove 2.
The bottom of the movable cone body 1 is provided with a plurality of threaded holes 6, and the pressure plate 7 is fixed with the threaded holes 6 at the lower part of the movable cone body 1 through a plurality of bolts 8 in a threaded manner.
The extrusion block 52 is made of 65 Mn.
The utility model discloses a theory of operation and use flow: when the movable cone and the static cone extrude and crush iron ore, after the lower end of the movable cone is worn for a long time, the movable cone body can be disassembled, the bolt 8 at the lower part of the pressure plate 7 is disassembled to take out the pressure plate 7, then the lower cone sleeve 3 is moved out from the annular clamping groove 2 at the lower part of the movable cone body 1, when the moved length exceeds the height of the T-shaped extrusion block 5, the damaged T-shaped extrusion block can be taken out from the T-shaped groove 4 to be replaced by a new one, then the lower taper sleeve 3 is reinstalled, thus, the maintenance is completed, the arranged T-shaped extrusion block 5 made of 65Mn can prolong the service life of the extrusion block, improve the wear resistance of the extrusion block and simultaneously prevent the lower taper sleeve 3 from being worn, when the lower taper sleeve 3 is partially worn, can be disassembled for repair welding and polishing, thus the service life of the movable cone can be integrally ensured, the movable cone is convenient to maintain, the whole movable cone is not required to be replaced, resources are greatly saved, and the economical efficiency is high.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
