Description

Technical Field

[0001] This utility model relates to the field of cone crusher feeding technology, and in particular to a cone crusher feeding device. Background Technology

[0002] A cone crusher is a machine used for crushing mineral materials and is widely used in the crushing and processing of sand and gravel aggregates. Cone crushers are fed by directly feeding material into the top hopper; the uniformity of the material distribution device directly affects the crushing efficiency and the lifespan of the liner plates.

[0003] As shown in the reference case "An Automatic Rotating Feeding Device for a Cone Crusher" (publication number CN220386793U), the impact of the falling material's own weight on the rotating wheel is used to achieve fully automatic rotating feeding of the cone crusher. Simultaneously, the feeding process utilizes a deceleration structure to slowly rotate the chute, which also buffers the falling material, resulting in more uniform feeding and further reducing the impact load on the cone crusher wall. Existing feeding devices mostly use a tilting feeding method. During the ore falling process, the ore will directly impact the blades on the surface of the rotating wheel. Over long-term operation, the blades are prone to rapid wear. Since the rotating wheel and blades are usually an integral casting structure, once damaged, the whole thing often needs to be replaced, resulting in high maintenance costs, inconvenient operation, long downtime, and affecting production continuity. Utility Model Content

[0004] Therefore, it is necessary to address the issue that existing feeding devices often employ a tilting feeding method, where the ore directly impacts the blades on the rotating wheel surface during its descent. Over long-term operation, this easily leads to rapid wear of the blades. Since the rotating wheel and blades are usually a single cast structure, damage often necessitates replacement of the entire unit, resulting in high maintenance costs, inconvenient operation, long downtime, and disruption to production continuity. To address this, a feeding device for a cone crusher is provided, comprising: a crusher with a feed inlet fixedly installed on one side; and a uniform feeding mechanism, which is located inside the feed inlet for uniformly distributing the material. The uniform feeding mechanism includes a guide frame located inside the feed inlet, a feeding assembly at the bottom of the guide frame, and a rotating component between the feeding assembly and the guide frame.

[0005] The fabric assembly includes a fixed plate fixedly installed inside the feed inlet. A rotary motor is fixedly installed on the top of the fixed plate, and a fabric frame is fixedly installed on the top of the rotary motor. The fabric frame is located at the bottom of the guide frame, and the guide frame is configured in a funnel shape.

[0006] The fabric frame is internally fixed with a wear-resistant plate, and the top of the wear-resistant plate is sloping.

[0007] A movable ring is fixedly installed at the bottom of the guide frame, and a support frame is slidably connected to the outside of the movable ring. A spring is fixedly installed inside the support frame, and the other end of the spring is in contact with the movable ring.

[0008] The diameter of the movable ring is larger than the diameter of the bottom outlet of the guide frame, and the diameters of both the movable ring and the support frame are smaller than the width of the fabric frame.

[0009] The fabric frame is U-shaped, and one side of the wear-resistant plate is rounded.

[0010] The rotating assembly includes connecting plates fixedly installed on the outside of the fabric frame. The other side of each of the two connecting plates is fixedly connected to the support frame. A rotating ring is rotatably installed on the outside of the support frame, and the rotating ring is fixedly connected to the inner wall of the feed inlet.

[0011] Multiple guide blocks are fixedly installed inside the support frame, and a guide groove is opened on the outer side of the movable ring, with each guide block slidably connected to the corresponding guide groove.

[0012] Beneficial effects 1. The guide frame and the feeding assembly work together to guide and buffer the falling ore, reducing the impact on the inner wall of the crusher. The feeding assembly rotates under the drive of the rotating component to distribute the ore evenly, avoiding uneven wear. At the same time, it drives the guide frame to rotate slowly, further dispersing the impact force and improving the equipment's lifespan and operational stability. 2. When the fabric frame rotates under the drive of the rotary motor, the connecting plate drives the support frame and guide frame to rotate synchronously. The rotating ring provides support and guidance, so that the falling material is first buffered and guided on the slowly rotating guide frame, and then enters the fabric frame to be evenly dispersed, reducing the intensity of concentrated impact.

[0021] The following is combined with Figures 1-4 This invention describes the feeding device for a cone crusher.

[0022] In one embodiment, a cone crusher feeding device includes: a crusher 100, with a feed inlet 200 fixedly installed on one side of the crusher 100; and a uniform feeding mechanism 300, which is disposed inside the feed inlet 200 for uniformly distributing and feeding material. The uniform feeding mechanism 300 includes a guide frame 310 disposed inside the feed inlet 200, a feeding assembly 320 disposed at the bottom of the guide frame 310, and a rotating assembly 330 disposed between the feeding assembly 320 and the guide frame 310.

[0023] In this embodiment, by setting up the coordinated operation between the guide frame 310 and the feeding assembly 320, effective initial guidance and buffering of the ore can be formed during the material feeding process, reducing the speed and intensity of the material directly impacting the inner wall of the crusher 100, and extending the equipment life. Driven by the rotating assembly 330, the feeding assembly 320 achieves rotary feeding, which can evenly disperse the ore into different areas of the crusher 100 cavity, avoiding localized wear or uneven loading caused by concentrated accumulation. Simultaneously, the rotating assembly 330 can also drive the guide frame 310 to rotate synchronously and slowly, making the force on the guide frame 310 more even, further reducing the impact damage caused by high-speed material feeding. It should be noted that the existing cone crusher 100 typically includes basic structures such as an upper feed inlet 200, a crushing chamber, an eccentric main shaft assembly, a conical moving cone, a fixed cone liner, and a lower discharge inlet. The guide frame 310 and the material distribution assembly 320 are located in the upper area of ​​the feed inlet 200 and only participate in the process of guiding and uniformly distributing materials. They do not involve key execution structures such as the moving cone, main shaft, and hydraulic cylinder inside the crusher 100. The guide frame 310 rotates in coordination with the material distribution assembly 320 through the rotating assembly 330, which can effectively buffer and guide the ore. The rotational movement of the material distribution assembly 320 only acts on the material falling process and does not interfere with the normal crushing operation in the lower crushing chamber.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the fabric assembly 320 includes a fixing plate 321 fixedly installed inside the feed inlet 200. A rotary motor 322 is fixedly installed on the top of the fixing plate 321. A fabric frame 323 is fixedly installed on the top of the rotary motor 322. The fabric frame 323 is located at the bottom of the guide frame 310, which is funnel-shaped.

[0025] In this embodiment, during material feeding, the material can be guided in a concentrated manner through the guide frame 310 and simultaneously fall into the fabric frame 323. The fabric frame 323 is rotated by the rotary motor 322 to perform rotary fabric feeding.

[0026] The fabric frame 323 is internally fixed with a wear-resistant plate 324, and the top of the wear-resistant plate 324 is set as a slope.

[0027] In this embodiment, the inside of the fabric frame 323 is provided with a detachable wear-resistant plate 324. The top of the wear-resistant plate 324 has a sloping structure, which can guide and divert the ore when it falls into the fabric frame 323 and withstand the direct impact of the material. When the wear-resistant plate 324 wears out due to long-term use, it can be removed and replaced separately from the fabric frame 323 without replacing the entire fabric assembly 320 structure.

[0028] A movable ring 326 is fixedly installed at the bottom of the guide frame 310. A support frame 325 is slidably connected to the outside of the movable ring 326. A spring 327 is fixedly installed inside the support frame 325. The other end of the spring 327 is in contact with the movable ring 326.

[0029] In this embodiment, when the guide frame 310 receives the falling material, due to the impact force of the ore, the instantaneous load borne by the guide frame 310 can be transmitted outward to the inside of the support frame 325 through the movable ring 326 at the bottom. The spring 327 installed inside the support frame 325 contacts the movable ring 326 and can generate elastic deformation during the impact, buffering and absorbing the force on the guide frame 310, thereby effectively reducing the structural stress caused by the instantaneous impact.

[0030] The diameter of the movable ring 326 is larger than the diameter of the bottom outlet of the guide frame 310, and the diameters of both the movable ring 326 and the support frame 325 are smaller than the width of the fabric frame 323.

[0031] In this embodiment, the diameter of the movable ring 326 is larger than the diameter of the discharge port at the bottom of the guide frame 310, which can effectively cover the discharge area and ensure that no material leakage occurs during the ore dropping process. At the same time, it enhances the connection stability between the guide frame 310 and the support structure. Since the diameters of both the movable ring 326 and the support frame 325 are smaller than the width of the lower feeding frame 323, it can be ensured that the dropped material falls stably onto the feeding frame 323.

[0032] The fabric frame 323 is U-shaped, and one side of the wear-resistant plate 324 is rounded.

[0033] In this embodiment, the fabric frame 323 is configured with a U-shaped structure, which can form an annular guiding space during the material feeding process, enhance the containment and guidance of the ore, and prevent the material from splashing or deviating from the fabric feeding area.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the rotating assembly 330 includes connecting plates 331 fixedly installed on the outside of the fabric frame 323. The other side of both connecting plates 331 is fixedly connected to the support frame 325. A rotating ring 333 is rotatably installed on the outside of the support frame 325. The rotating ring 333 is fixedly connected to the inner wall of the feed inlet 200.

[0035] In this embodiment, when the fabric frame 323 rotates under the drive of the rotary motor 322, the connecting plate 331 drives the support frame 325 to rotate synchronously. A rotating ring 333 is sleeved on the outer side of the support frame 325. The rotating ring 333 can rotate relative to the structure fixed on the inner wall of the feed inlet 200, so that the entire guide frame 310, support frame 325 and fabric frame 323 can rotate in a coordinated manner. This allows the material to be buffered and guided before entering the fabric frame 323 for secondary dispersion and distribution when it falls onto the surface of the slowly rotating guide frame 310, thereby reducing the intensity of concentrated impact of the material.

[0036] Multiple guide blocks 332 are fixedly installed inside the support frame 325. A guide groove is provided on the outer side of the movable ring 326, and the multiple guide blocks 332 are slidably connected to the corresponding guide groove.

[0037] In this embodiment, when the guide frame 310 moves with the movable ring 326 in a buffered vertical direction, the guide block 332 can slide synchronously along the guide groove to ensure that the support frame 325 can stably drive the movable ring 326 to rotate.

[0038] Working Principle: During operation, ore falls from the top of the crusher 100 into the feed inlet 200 and is initially guided by the guide frame 310. The guide frame 310 has a funnel-shaped structure, which can effectively guide the material to fall and buffer part of the impact force. At the same time, a movable ring 326 is fixedly connected to the bottom of the guide frame 310. The movable ring 326 is connected to the support frame 325 through a spring 327. At the moment of impact of the ore, the spring 327 can generate elastic deformation, buffering and absorbing the impact load of the guide frame 310. The ore continues to fall into the inside of the distribution frame 323. The rotary motor 322 drives the distribution frame 323 to rotate, realizing the uniform distribution of ore. Wear-resistant plates 324 are installed inside the distribution frame 323. The top of the wear-resistant plate 324 is inclined, and part of the surface is arc-shaped, which can guide the material to slide along the inner wall and reduce direct impact. The fabric frame 323 is U-shaped to improve material holding capacity and prevent splashing. The outer side of the fabric frame 323 is connected to the support frame 325 via a connecting plate 331. While the rotary motor 322 drives the fabric frame 323 to rotate, the rotating component 330 drives the guide frame 310 to rotate slowly and synchronously via the support frame 325. The rotating ring 333 is connected to the inner wall of the feed inlet 200, providing stable support for the rotation. The slow rotation of the guide frame 310 further achieves material drop buffering and uniform guidance.

[0039] It should be noted that the crusher and rotary motor mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the crusher and rotary motor can be powered by built-in power supply or mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
