Background

The crushing device is an important component in mining machinery and equipment, and is mainly used for crushing mined ores and performing subsequent processing. Crushing devices are of various types, and usually jaw crushers are used for crushing minerals, but the crushing effect is not good, so that cone crushers are appeared later, and the cone crushers are widely used in the industry at present.

The cone crusher mainly comprises a moving cone and a static cone, wherein the moving cone eccentrically rotates under the action of an eccentric shaft sleeve, the distance between the moving cone and the static cone continuously changes to realize mineral extrusion, and when the cone crusher is used for a long time, the surfaces of the moving cone and the static cone gradually wear. When the abrasion reaches a certain degree, the movable cone and the static cone need to be replaced, the whole replacement of the movable cone and the static cone is very troublesome, the cost is extremely high, and the purchase of a new cone crusher is not inferior to the purchase of a new cone crusher. Therefore, in order to reduce the cost of replacing the movable cone and the static cone, the surface of the movable cone and the surface of the static cone of the existing cone crusher are provided with a layer of wear-resistant lining, and the normal use of the cone crusher can be ensured only by replacing the wear-resistant lining.

But current wear-resisting bush adopts a plurality of bolts and moves awl, quiet awl body coupling usually, but cone crusher internal environment is comparatively abominable at mineral crushing in-process, and the broken extrusion of mineral makes the bolt that exposes outside produce deformation easily, and then makes the bolt be difficult to take off, influences wear-resisting bush's change. This problem is particularly pronounced on the moving cone, since the mineral is mainly carried by the moving cone inside the cone crusher.

Detailed Description

For better understanding of the present invention, the present invention will be described in conjunction with the accompanying drawings and the following embodiments

And (5) detailed description is further provided.

Example 1

The utility model provides a cone crusher moves awl structure, including moving awl body 9 and the cylindric bush 10 of circular cone, same high department evenly is provided with a plurality of fixture blocks 8 along circumference on the bush 10 inner wall, move awl body 9 set up with the draw-in groove 13 of 8 complex L shapes of fixture block, draw-in groove 13 includes vertical section and horizontal segment, it is connected with the circular cone head 1 that is used for axial fixity bush 10 to move awl body 9 top, 1 bottom center of circular cone head is provided with inserts spliced pole 2 that moves in the awl body 9, spliced pole 2 and move and pass through threaded connection between the awl body 9, it is provided with through spliced pole 2 inside and driven locking mechanical system who is used for locking fixture block 8 to move awl body 9.

The working principle is as follows: when the bushing 10 is installed, the bushing is sleeved on the movable cone body 9, specifically, the bushing 10 is sleeved on the movable cone body 9 from top to bottom, wherein the clamping block 8 on the bushing 10 corresponds to the clamping groove 13 on the movable cone body 9 up and down. When the bushing 10 is sleeved on the movable cone body 9, the clamping block 8 enters the clamping groove 13 from top to bottom, specifically, enters the bottom of the vertical section of the clamping groove 13, and at the moment, the inner wall of the bushing 10 is tightly attached to the surface of the movable cone body 9. The bushing 10 is then rotated horizontally, thereby moving the latch 8 into the horizontal section of the latch slot 13. And finally, installing the conical head 1, screwing the connecting column 2 into the top of the movable cone body 9 from top to bottom, fixing the top of the lining 10 along the axis, and driving the locking mechanism to lock the fixture block 8 through screwing the connecting column 2 so as to keep the position of the fixture block 8 fixed and further keep the lining 10 and the movable cone body 9 relatively fixed. When the connecting column 2 is disassembled, the connecting column is screwed out, so that the locking mechanism is unlocked for the clamping block 8, and the bushing 10 is rotated reversely and then taken out upwards.

It is preferable to perform the following settings: the width of the vertical section is the same as that of the fixture block 8, and the width and the height of the horizontal section are the same as those of the fixture block 8; the arrangement facilitates the installation and the matching between the clamping block 8 and the clamping groove 13.

Example 2

The embodiment is improved on the basis of embodiment 1:

locking mechanical system is including seting up the centre bore 5 on moving awl body 9, set up a plurality of horizontally locking grooves 15 that correspond draw-in groove 13 of intercommunication respectively on the 5 bottom inner walls of centre bore, be provided with locking piece 14 in the locking groove 15, be provided with the resilience spring 16 of cover on locking piece 14 in the locking groove 15, be provided with the elastic airbag 18 who is used for outside promotion locking piece 14 in the fixed chamber, elastic airbag 18 top is provided with clamp plate 6, clamp plate 6 upper surface center is provided with the stripper bar 4 of top and 2 bottom contacts of spliced pole. The elastic bladder 18 is spindle-shaped when uncompressed and its outer surface does not contact the locking block 14. During the installation, spliced pole 2 screw in and promote the squeeze bar 4 and clamp plate 6 downwards to flatten elasticity gasbag 18, and then the height of elasticity gasbag 18 reduces and the external diameter increases, realizes pushing locking block 14 to the outside along locking groove 15, lets locking block 14 end stretch out to draw-in groove 13 promptly, the compression of rebound spring 16 this moment. The side surface of the locking block 14 is tightly attached to the side surface of the fixture block 8 to limit the fixture block 8, so that the fixture block 8 is locked in the horizontal section of the clamping groove 13. When the connecting column 2 is screwed out, the shape of the elastic air bag 18 is recovered, the locking block 14 retracts under the elastic force action of the rebound spring 16, and the limiting and locking of the clamping block 8 are further released.

In order to increase the contact area between the locking block and the elastic airbag and improve the contact stability, the push plate 7 is arranged at the tail end of the locking block 14, a horizontal rebound groove 17 is formed in the groove wall at the top of the locking groove 15 in order to facilitate the arrangement of the rebound spring 16, the rebound spring 16 is arranged in the rebound groove 17, and one end of the rebound spring is fixedly connected with the surface of the top of the push plate 7.

The cone head 1 bottom is simple only to cover at bush 10 with move awl body 9 top, there is the horizontally gap cone head 1 bottom and bush 10 top, and then particulate matter such as the dust that produces in the broken process of mineral can very easily enter into to moving the inside spliced pole 2 department of awl body 9 through the gap, influence threaded connection's normal cooperation, so bush 10 top external diameter reduces and forms reducing section 3, 1 bottom edge downwardly extending of cone head is in reducing section 3 and inseparable knot is on reducing section 3. The existence of reducing section 3 becomes the horizontally gap tortuous, makes the granule be difficult to directly get into inside the mantle body 9 through the gap.

The outer diameter of the bottom of the movable cone body 9 is increased to form an annular boss 11, an annular expanding section 12 corresponding to the boss 11 is arranged on the inner wall of the bottom of the bushing 10, and the expanding section 12 is tightly buckled on the boss 11. The boss 11 is matched with the expanding section 12, so that the auxiliary positioning and supporting of the installation of the bush 10 can be realized, and the installation of the bush 10 is convenient.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
