Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention. It is to be understood that the drawings are provided solely for the purposes of reference and illustration and are not intended as a definition of the limits of the invention. The connection relationships shown in the drawings are for clarity of description only and do not limit the manner of connection.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
It should be noted that the "up" and "down" directions described herein refer to the directions in which the side close to the ground is down and the side away from the ground is up in the normal use state of the cone crusher of the present invention, i.e., the orientation of fig. 2.
In the cone crusher according to the present invention, the inner and outer orientations are defined as inner and outer, respectively, on the side close to the axial central axis of the annular cover body in a normal use state.
The invention is further described with reference to the following figures and specific embodiments.
Example 1:
as shown in fig. 2 and 3, the sealing structure of the cone crusher of the present embodiment includes a casing 1, a movable cone 5 disposed in the casing 1, an annular cover 2 covering a balance ring 7 of the cone crusher, and an annular body 3 sleeved outside the annular cover 2; a sealing ring 9 is arranged between the annular cover body 2 and the casing 1, the upper end of the annular cover body 2 extends into the movable cone 5, and the movable cone 5 is provided with an avoiding groove 52 for avoiding the annular cover body 2; the side wall of the avoiding groove 52 is provided with an annular groove 51 with an opening facing the annular cover body 2; the lower surface of the annular body 3 is a spherical surface, the annular body 3 is in clearance fit with the annular groove 51, and the inner surface of the annular body 3 abuts against the outer surface of the annular cover body 2.
It should be noted that in this embodiment, the orientations and connection relationships between the dynamic cone 5 and the casing 1 and between the balance ring 7 and the casing 1 are the same as those in the prior art and are all known in the art, and therefore, the description thereof is omitted.
As shown in fig. 4, gaps 8 are provided between the upper surface of the annular body 3 and the upper sidewall of the annular groove 51 and between the outer surface of the annular body 3 and the bottom of the annular groove 51, so that the annular body 3 can move freely in the annular groove 51 during the rotation and swing of the movable cone 5, and because the lower surface of the annular body 3 is a spherical surface, the lower surface of the annular body 3 is always attached to the lower sidewall 4 of the annular groove 51 under the self-weight action of the annular body 3, and meanwhile, the inner surface of the annular body 3 is attached to the outer surface of the annular cover body 2, and the upper end of the annular cover body 2 extends into the movable cone 5, so that foreign matters such as dust cannot enter the annular cover body 2 from the upper part of the annular cover; as shown in fig. 2 and 3, a seal ring 9 is disposed between the annular cover 2 and the casing 1, so that foreign matters such as dust cannot enter the annular cover 2 from the lower portion of the annular cover 2, thereby achieving a sealing effect.
The sealing ring 9 may be disposed between the lower end surface of the annular cover body 2 and the casing 1, specifically, an annular groove may be formed on the lower end surface of the annular cover body 2 or the casing, and then the sealing ring 9 is disposed in the annular groove; the sealing ring 9 can also be arranged between the outer peripheral wall of the lower part of the annular cover body 2 and the casing 1, specifically, a vertical hole is formed in the casing 1, the lower part of the annular cover body 2 is arranged in the hole, an accommodating groove for accommodating the sealing ring 9 can be formed in the outer peripheral wall of the lower part of the annular cover body 2 or the hole wall of the hole, and then the sealing ring 9 is arranged in the accommodating groove; obviously, the arrangement mode of the sealing ring 9 in the present invention is not limited to the above-mentioned several modes, as long as the sealing between the casing 1 and the annular cover body 2 can be realized, and the foreign matters such as dust can be prevented from entering the annular cover body 2 through the gap between the annular cover body 2 and the casing 1.
Because the annular cover body 2 does not limit the degree of freedom of the annular body 3 in the vertical direction, after the spherical shell tile 6 is abraded, the movable cone 5 moves downwards, and the annular cover body 2 does not exert extra vertical force on the annular body 3, so that the extrusion amount of the annular body 3 is prevented from being increased; meanwhile, a gap 8 is formed between the annular body 3 and the annular groove 51, so that even if the rotation center of the movable cone 5 changes after the spherical shell 6 is worn, the movable cone 5 cannot extrude the annular body 3, and the extrusion amount of the annular body 3 is increased; it follows that the wear of the spherical shell 6 does not lead to the destruction of the sealing structure of the invention.
The annular cover body 2 and the annular body 3 are not required to be bonded by glue, so that the maintenance time is reduced; meanwhile, compared with the prior art, the processing precision of the annular cover body 2 and the annular body 3 is lower.
In this embodiment, the annular body 3 is made of MC cast nylon to improve the wear resistance and oil resistance of the annular body 3, and at the same time, the self-lubricating property is also good.
The cone crusher in this embodiment includes the sealing structure, and since the present invention only improves the sealing structure in the cone crusher, other structures of the cone crusher can adopt specific structures in the prior art, and are not described herein again.
Example 2:
the present embodiment is different from embodiment 1 in that, as shown in fig. 4, a surface of the lower side wall 4 of the annular groove 51 facing the annular body 3 is a spherical surface adapted to a lower surface of the annular body 3, so that a contact area between the lower surface of the annular body 3 and an upper surface of the lower side wall 4 of the annular groove 51 is increased, and sealing performance is improved.
Example 3:
the difference between this embodiment and embodiment 1 or embodiment 2 is that, as shown in fig. 2 and 4, in this embodiment, the lower sidewall of the annular groove 51 is detachably connected to the movable cone 5, so that when the annular body 3 is disassembled, the lower sidewall 4 can be disassembled first, so that the annular body 3 can be kept in a free state during the disassembly and assembly, and the performance of the annular body 3 is prevented from being reduced or even damaged due to excessive pressing of the annular body 3.
Example 4:
the difference between this embodiment and embodiment 1 or embodiment 2 or embodiment 3 is that, as shown in fig. 2 and 3, in this embodiment, the lower end of the annular cover body 2 is provided with a connecting flange protruding outwards; the connecting flange is detachably connected with the machine shell 1, and a positioning ring 21 extends downwards from the bottom end of the connecting flange; the casing 1 is provided with a positioning hole 11 matched with the outer circle of the positioning ring 21, so that the annular cover body 2 can be positioned on the casing 1, interference between the annular cover body 2 and other parts caused by uncertain position of the annular cover body 2 in work is avoided, and meanwhile, the adjustment time can be shortened when the annular cover body 2 is installed.
Example 5:
the difference between this embodiment and embodiment 4 is that, as shown in fig. 2 and 3, in this embodiment, the sealing ring 9 is disposed between the positioning hole 11 and the positioning ring 21, if the sealing ring 9 is disposed between the lower end face of the annular cover body 2 and the casing 1, if the groove for accommodating the sealing ring 9 is formed on the lower end face of the annular cover body 2, the sealing ring 9 is easily dropped by gravity during the installation process, and if the groove is formed on the casing 1, on the one hand, the increase of the groove increases the processing difficulty due to the larger casing 1; on the other hand, if the seal ring 9 is not mounted in the groove, the installer may not notice it.
Example 6:
the difference between this embodiment and embodiment 5 is that, as shown in fig. 2 and 3, in this embodiment, an annular groove for accommodating the sealing ring 9 is formed on the outer circumferential surface of the positioning ring 21, and if the annular groove is formed on the housing 1, on the one hand, the processing difficulty is increased; on the other hand, if the seal ring 9 is not installed in the groove, the installer may not necessarily notice it; moreover, because the inner surface of the sealing ring 9 must be in interference fit with the outer circular surface of the positioning ring 21, when the annular cover body 2 is installed, the annular cover body 2 is easy to push the sealing ring 9 out of the annular groove.
Example 7:
the present embodiment is different from any one of embodiments 1 to 6 in that, as shown in fig. 5, in the present embodiment, the balance ring 7 includes an annular connecting body 72 and a weight body 71 fixed to an upper end of the annular connecting body 72; the weight 71 is in the form of a tile. In this embodiment, the annular connecting body 72 is a revolving body, and the counterweight body 71 can also be made of the revolving body by simple cutting, so that the shape is simpler under the condition of ensuring the centrifugal force, and the counterweight body can be manufactured only by turning and cutting.
Example 8:
the difference between this embodiment and embodiment 7 is that in this embodiment, the weight body 71 and the annular connecting body 72 are coaxially arranged, so that before the weight body 71 is cut out, the revolution surfaces and the end surfaces of one end of the annular connecting body 71 and the weight body 71 can be machined by one clamping, the machining process is simplified, and the cost is saved.
The invention is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
