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. 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.
