[0002] A cone crusher is a kind of crushing machinery suitable for raw materials in the metallurgy, construction, road construction, chemical and silicate industries. Because of its large crushing ratio, high efficiency, low energy consumption and uniform product particle size, it is suitable for medium crushing and fine crushing of various ores and rocks. Therefore, the cone crusher is a commonly used machine in the ore processing industry.

[0003] However, since the existing cone crusher conveys the stone material for feeding through a belt conveyor for crushing, the feeding point always falls on a point / surface (i.e., the cone cap), and the cone cap is precisely the key hub point where the cone assembly is connected to the crushing wall. In this way, when the stone material falls from the cone cap for a long time, it will not only cause wear of the cone cap, but also it is difficult for the stone material to evenly fall from the cone cap into the cone pipe for material distribution, greatly reducing the service life of the cone cap.

[0009] Further, a plurality of sharp convex portions are provided on each mounting projection along its circumferential direction and extending direction; alternatively, each mounting projection is a threaded rod structure.

[0010] Further, the auxiliary feeding member includes a first cylinder and a second cylinder arranged from inside to outside, the second cylinder is rotatably connected to the first cylinder, and a plurality of mounting members are arranged inside the first cylinder so that the first cylinder drives the plurality of mounting members to rotate.

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] In order to solve the problem that the conical cap is easily worn during blanking in the prior art, the present utility model provides an abrasion-resistant structure and a conical crusher having the same.

[0024] Please refer to Figures 1 to 3 As shown, on one hand, applying the technical solution of the present utility model, the abrasion-resistant structure includes a conical pipe 10, a feed pipe 20, and an auxiliary feed component 30; the conical pipe 10 has a first end and a second end arranged from top to bottom, and the cross-sectional area of the first end is smaller than that of the second end; the feed pipe 20 is arranged on the first end of the conical pipe 10 and is communicated with the conical pipe 10, and the feed pipe 20 has a feed port 21 for feeding; the auxiliary feed component 30 is arranged on the first end of the conical pipe 10 and is arranged around the feed pipe 20, and a protective medium layer 40 is provided between the auxiliary feed component 30 and the feed pipe 20, and the auxiliary feed component 30 has an auxiliary feed port 31 communicated with the feed port 21, so that the material falls from the auxiliary feed port 31 and then flows into the conical pipe 10 through the feed port 21; wherein, the length of the auxiliary feed component 30 along the vertical direction is greater than the length of the feed pipe 20.

[0025] On one hand, applying the technical solution of this embodiment, during feeding, the material falls from the auxiliary feed port 31 of the auxiliary feed component 30 and impacts the protective medium layer 40 between the auxiliary feed component 30 and the feed pipe 20 during the falling process and then falls into the conical pipe 10 from the feed port 21, greatly reducing the wear of the feed pipe 20, and moreover, enabling the material to achieve the effect of uniform cloth feeding, controlling the crushing particle size of the material, and under the action of the auxiliary feed component 30, enabling the material to effectively fall into the conical pipe 10, thereby solving the problem that the conical cap is easily worn during blanking in the prior art.

[0026] In this embodiment, the material is stone.

[0027] In an exemplary embodiment, the auxiliary feed component 30 is rotatably arranged, and a plurality of mounting members 32 are spaced apart on the inner wall of the auxiliary feed component 30 along its extending direction, and the plurality of mounting members 32 are arranged to avoid the feed port 21, so that the plurality of mounting members 32 strike the material falling into the auxiliary feed component 30 from the auxiliary feed port 31. In this way, when the material falls from the auxiliary feed port 31, it will impact the protective medium layer 40, and under the rotation of the plurality of mounting members 32, the material is stirred and struck, so that the material is uniformly cloth-fed and the particle size of the material is controlled under multiple strikes, and then the material uniformly falls into the conical pipe 10 through the feed port 21 at a certain particle size.

[0028] Preferably, each mounting member 32 includes a plurality of mounting protrusions 320, and the plurality of mounting protrusions 320 are sequentially arranged at intervals along the circumferential direction of the auxiliary feeding member 30. In this way, when the auxiliary feeding member 30 drives the plurality of mounting protrusions 320 to rotate, the materials collide with each other between two adjacent mounting protrusions 320, not only stirring the materials to make them evenly distributed, but also after multiple impacts of the materials with the mounting protrusions 320, so that the materials are controlled within a certain particle size and fall into the conical pipe 10 from the feed port 21.

[0029] Optionally, each mounting member 32 is of an annular structure, and the distance between the inner ring wall and the outer ring wall of the mounting member 32 is two-thirds of the distance between the feed pipe 20 and the auxiliary feeding member 30. In this way, the mounting member 32 can avoid the falling of the materials when rotating, and at the same time, under the rotation of the plurality of mounting members 32, the materials can be stirred to make them evenly distributed, and moreover, when the materials are stirred, the materials can collide between two adjacent upper and lower mounting members 32 to control the particle size of the materials within a certain range.

[0030] In this embodiment, optionally, one mounting protrusion 320 in one mounting member 32 and the corresponding mounting protrusions 320 in other mounting members 32 are sequentially arranged or staggered along the extending direction of the auxiliary feeding member 30. In this way, corresponding selection can be made according to the use requirements and actual working conditions; when the mounting protrusions 320 in two adjacent mounting members 32 are sequentially arranged, the materials can be evenly stirred for distribution, while when the mounting protrusions 320 in two adjacent mounting members 32 are staggered, the materials can be more fully impacted with the plurality of mounting protrusions 320, so that the materials are controlled within a certain particle size range for feeding.

[0031] Optionally, as Figure 3 shown, a plurality of sharp protrusions 3201 are provided on each mounting protrusion 320 along its circumferential direction and extending direction; or, each mounting protrusion 320 is of a threaded rod structure. In this way, when the materials collide between two adjacent mounting protrusions 320, the sharp protrusions 3201 or threaded segments on the mounting protrusions 320 can be used to strike and rub the materials to break the materials and control their particle size within a certain range.

[0032] In an exemplary embodiment, the auxiliary feeding member 30 includes a first cylinder and a second cylinder arranged from the inside to the outside, the second cylinder is rotatably connected to the first cylinder, and a plurality of mounting members 32 are arranged in the first cylinder so that the first cylinder drives the plurality of mounting members 32 to rotate. In this way, by controlling the rotation of the second cylinder in the first cylinder to drive the plurality of mounting members 32 to stir and strike the materials falling into the auxiliary feeding member 30, the uniform distribution of the materials and the control of the particle size are realized.

[0033] Specifically, a first annular protrusion is provided on the outer cylindrical wall of the first cylinder body along its circumferential direction, and a first annular groove is provided on the inner cylindrical wall of the second cylinder body along its circumferential direction. The first annular protrusion rotatably extends into the first annular groove; alternatively, a second annular groove is provided on the outer cylindrical wall of the first cylinder body along its circumferential direction, and a second annular protrusion is provided on the inner cylindrical wall of the second cylinder body along its circumferential direction. The second annular protrusion rotatably extends into the second annular groove. In this way, the first cylinder body and the second cylinder body are slidably connected. By controlling the rotation of the second cylinder body, it rotates within the first cylinder body and relative to the first cylinder body, so as to drive the rotation of a plurality of mounting members 32 to stir and strike the material.

[0034] In this embodiment, the auxiliary feeding component 30 has a cylindrical structure.

[0035] Optionally, the auxiliary feeding component 30 has a conical structure, and the cross-sectional area of the auxiliary feeding component 30 gradually decreases along the direction towards the first end of the conical pipe 10. With the above settings, the structures of the first cylinder body and the second cylinder body are the same, which is convenient for the second cylinder body to rotate relative to the first cylinder body. At the same time, when the auxiliary feeding component 30 has a conical structure, it can accommodate more falling stones.

[0036] In this embodiment, the protective medium layer 40 is formed by laying materials. Horizontally, the protective medium layer 40 is flush with the feeding port 21 of the feeding pipe 20; wherein, the laying materials and the material are made of the same substance. With the above settings, the laying materials are stones. By pre-laying the stones between the auxiliary feeding component 30 and the feeding pipe 20 at a height flush with the pipe orifice of the feeding pipe 20, when feeding the materials, the falling point forms a state where the stones impact each other, greatly alleviating the wear on the feeding pipe 20. At the same time, under the stirring and striking of the plurality of mounting members 32 on the auxiliary feeding component 30, the stones are evenly distributed, and the particle size of the stones is controlled within a certain range.

[0037] On the other hand, applying the technical solution of the present utility model provides a cone crusher, which includes the above-mentioned wear-resistant structure and a crusher main body, and the wear-resistant structure is installed on the crusher main body. In this way, the cone crusher with the above-mentioned wear-resistant structure greatly improves the service life and at the same time improves the crushing efficiency of the stones.

[0038] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0039] The wear-resistant structure includes a conical pipeline, a feed pipe, and an auxiliary feeding component: The conical pipeline has a first end and a second end arranged from top to bottom, and the cross-sectional area of the first end is smaller than that of the second end; the feed pipe is arranged on the first end of the conical pipeline and is communicated with the conical pipeline, and the feed pipe has a feed port for feeding; the auxiliary feeding component is arranged on the first end of the conical pipeline and surrounds the feed pipe, a protective medium layer is provided between the auxiliary feeding component and the feed pipe, and the auxiliary feeding component has an auxiliary feed port communicated with the feed port, so that the material falls from the auxiliary feed port and then flows into the conical pipeline through the feed port; wherein, the length of the auxiliary feeding component in the vertical direction is greater than the length of the feed pipe. In this way, when feeding, the material falls from the auxiliary feed port of the auxiliary feeding component and impacts the protective medium layer between the auxiliary feeding component and the feed pipe during the falling process and then falls into the conical pipeline from the feed port, greatly reducing the wear of the feed pipe, and enabling the material to achieve the effect of uniform cloth feeding, controlling the crushing particle size of the material, and under the action of the auxiliary feeding component, enabling the material to effectively fall into the conical pipeline, thereby solving the problem that the conical cap is easily worn during blanking in the prior art.
