Description

Technical Field

[0001] This utility model relates to the technical field of cone crushers, specifically a novel cone crusher. Background Technology

[0002] A cone crusher is a device used for crushing ores and rocks, widely used in metallurgy, construction, road building, chemical, and silicate industries. Depending on the crushing principle and product particle size, it can be divided into various models, suitable for medium and fine crushing of various ores and rocks. The working principle of a cone crusher is that the rotation of the motor drives the eccentric sleeve to rotate, causing the crushing wall of the cone crusher to oscillate around a fixed point under the force of the eccentric sleeve. This movement causes the crushing wall to sometimes approach and sometimes move away from the crushing wall surface fixed on the adjusting sleeve, thus subjecting the ore to continuous impact, compression, and bending within the crushing chamber, ultimately achieving ore crushing.

[0003] Currently, cone crushers typically operate with a full-load operation, where material is continuously filled into the crushing chamber via a feeding device such as a vibrating feeder until the material level reaches above the top of the moving cone, forming a stable "material layer." In this case, the crushing process relies primarily on the mutual compression and friction between the material layers, rather than solely on the direct impact of the liner plates. This improves crushing efficiency and capacity, and the stable material layer avoids idle time, allowing the crusher to operate at full load and maintain continuous operation. Simultaneously, the material layer acts as a "buffer," reducing the impact load directly borne by the liner plates. For example, when crushing hard materials, a full-load operation reduces the wear rate of the liner plates, and the material quality within the crushing chamber is stable under full-load conditions, reducing equipment vibration and impact. However, when oversized materials exceeding one-tenth of the feed volume are large, these large materials can easily become stuck at the feed inlet under full-load conditions, causing the liner plates to break due to localized overload, reducing their service life. Therefore, we propose a novel cone crusher. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of cone crusher, which has the advantage of screening out oversized materials. It solves the problem that when the proportion of oversized materials in the feed exceeds one-tenth, the oversized materials are easily stuck in the feed inlet under full material conditions, causing the feed end of the liner to break due to local overload, thus reducing the service life of the liner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel cone crusher, comprising:

[0006] The cone crusher body has a feed inlet at the middle of its top.

[0007] A support rod is provided, with a positioning bolt threaded to its top. A limit plate is fixedly installed on the top of the support rod by the positioning bolt. Springs are sleeved at both the upper and lower ends of the outer surface of the support rod. A guide sleeve that slides on the outer surface of the support rod is fixedly connected between the two springs. A bearing ring is fixedly connected to one side of the guide sleeve.

[0008] The sieve hopper has a guide ring fixedly connected to the upper end of its inner wall. Multiple equal-angled distribution rods are fixedly connected to the inner side of the guide ring. A feed ring is fixedly connected to the end of each distribution rod away from the guide ring. A discharge pipe extending to the outside of the sieve hopper is fixedly connected to the bottom of the feed ring. Vibration motors are fixedly installed on both the front and rear sides of the sieve hopper.

[0009] Preferably, there are four support rods, which are distributed at equal angles and fixedly connected to the top of the cone crusher body.

[0027] Example 1

[0028] Please see Figures 1-5 As shown, this utility model provides a technical solution: a novel cone crusher, comprising:

[0029] The cone crusher body 1 has a feed inlet 101 at the middle of the top of the cone crusher body 1;

[0030] The support rod 3 has a positioning bolt 302 threadedly connected to its top. A limit plate 301 is fixedly installed on the top of the support rod 3 by the positioning bolt 302. Springs 304 are sleeved on both the upper and lower ends of the outer surface of the support rod 3. A guide sleeve 305 that slides on the outer surface of the support rod 3 is fixedly connected between the two springs 304. A bearing ring 303 is fixedly connected to one side of the guide sleeve 305.

[0031] The sieve hopper 2 has a guide ring 201 fixedly connected to the upper end of its inner wall. Multiple equal-angled distribution rods 204 are fixedly connected to the inner side of the guide ring 201. A feed ring 202 is fixedly connected to the end of the distribution rod 204 away from the guide ring 201. A discharge pipe 203 extending to the outside of the sieve hopper 2 is fixedly connected to the bottom of the feed ring 202. Vibration motors 4 are fixedly installed on both the front and rear sides of the sieve hopper 2.

[0032] There are four support rods 3, which are distributed at equal angles and fixedly connected to the top of the cone crusher body 1. The screen hopper 2 is fixedly connected to the top of the bearing ring 303, and the lower end of the screen hopper 2 is placed inside the feed inlet 101. The top of the discharge pipe 203 located inside the screen hopper 2 is provided with a guide slope. The discharge pipe 203 is inclined. The material distribution rod 204 is inclined between the guide ring 201 and the feed ring 202.

[0033] This technical solution: By setting up the screening hopper 2, since the volume of the screening hopper 2 is larger than that of the feed inlet 101, it can process more material, ensuring that the feed inlet 101 is always full. After receiving material from the stable feeding conveyor belt, the vibrating motor 4 drives the screening hopper 2 to vibrate. With the assistance of the bearing ring 303 and the guide sleeve 305, the balance of the spring 304 can be broken, which helps to improve the vibration intensity of the screening hopper 2. The screening hopper 2 in the vibrating state can be guided by the material guide ring 201 and the material distribution rod. With the assistance of 204, oversized materials larger than the specified size are screened. Under the influence of the inclined setting of the dividing rod 204, the screened oversized materials can move closer to the feed ring 202. Finally, under the influence of gravity, they are discharged and collected through the discharge pipe 203. This can avoid the situation where oversized materials get stuck in the feed inlet when the material is full, and ensure the normal use of the liner. With the setting of the positioning bolt 302, after unscrewing the positioning bolt 302 and removing the limit plate 301 and spring 304, the screen hopper 2 can be disassembled or quickly replaced as needed.

[0034] Example 2

[0035] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a buffer rubber ring 5 is fixedly connected to the bottom of the screen hopper 2, and the bottom of the buffer rubber ring 5 contacts the inner wall of the feed inlet 101.

[0036] This technical solution: By setting the buffer rubber ring 5, rigid collisions can be avoided between the screen hopper 2 and the inner wall of the feed inlet 101 when the screen hopper 2 vibrates.

[0037] Example 3

[0038] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, an electric push rod 205 is fixedly installed at the right end of the bottom of the discharge pipe 203. The extended end of the electric push rod 205 is fixedly connected to a sealing plate 206 that is compatible with the feed ring 202. A protective cover 207 is fixedly connected to the outside of the electric push rod 205 and at the bottom of the discharge pipe 203.

[0039] This technical solution: By setting up the electric push rod 205, when the sieve hopper 2 screens out a small amount of oversized material, the external controller controls the electric push rod 205 to drive the sealing plate 206 into the lower part of the feed ring 202, thereby blocking the feed ring 202. When the sieve hopper 2 screens out oversized material that meets the discharge standard, the external controller controls the electric push rod 205 to drive the sealing plate 206 to retract, so that the large material approaching the feed ring 202 can be discharged outward through the discharge pipe 203. After completion, the external controller controls the electric push rod 205 to drive the sealing plate 206 into the lower part of the feed ring 202 again to achieve blocking, which helps to reduce the discharge of material that meets the particle size standard.

[0040] It should be noted that the electric push rod 205 and the vibration motor 4 used in this equipment can be purchased directly from the market and are powered by mains electricity. At the same time, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here. The diameter of the feed ring 202 is set according to the specifications of large materials. If materials larger than the diameter of the feed ring 202 appear, manual intervention is required to remove them in time.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
