Description

Technical Field

[0001] This utility model belongs to the technical field of crushers, specifically relating to an anti-material accumulation device for a cone crusher. Background Technology

[0002] A cone crusher is a medium-fine crushing equipment that uses the squeezing and bending action between a moving cone and a fixed cone to crush materials. It is widely used in mining, building materials and other fields. Its core structure includes a crushing chamber, a main shaft, an eccentric sleeve and a hydraulic adjustment system. It achieves high-efficiency operation through the principle of layered crushing. The anti-accumulation device is an auxiliary system designed to prevent wet, sticky or powdery materials from accumulating at the bottom of the crushing chamber. It usually adopts a vibrating scraper, air jet or a composite structure to prevent material adhesion and blockage, and ensure smooth discharge and continuous and stable operation of the equipment.

[0003] Currently, when cone crushers process iron ore, due to the strong adsorption characteristics of ferromagnetic materials, fine iron powder easily forms a stubborn accumulation layer on the surface of the liner. This accumulation is not only difficult to completely remove by conventional mechanical scraping or airflow cleaning, but it also leads to a reduction in the effective volume of the crushing chamber and increased local wear of the liner, thereby affecting crushing efficiency and equipment operation stability, and even causing frequent shutdowns for material cleaning.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example

[0031] Reference Figures 1-5 This is an embodiment of the present utility model. This embodiment provides an anti-accumulation device for a cone crusher, including a bearing mechanism 100, a housing 110, a crushing component 120 disposed inside the housing 110 and directionally adsorbing iron powder by a magnetic field, and a driving component 130 for controlling the operation of the crushing component 120.

[0032] like Figure 2 and Figure 3 The scraping mechanism 200 includes a horizontal plate 210, a miniature waterproof motor 220 fixedly installed on the top of the horizontal plate 210, a shaft 230 fixedly installed on the output end of the miniature waterproof motor 220, a connecting plate 240 fixedly installed on the end of the shaft 230, and an adaptive vibration component 250 disposed on the outside of the connecting plate 240.

[0033] The crushing assembly 120 includes a cylinder 121 fixedly installed in the inner cavity of the outer shell 110, an adsorption groove 122 opened on the inner wall of the cylinder 121, a permanent magnet module 123 fixedly installed on the outer side of the adsorption groove 122, and a chip discharge pipe 124 fixedly installed on the outer side of the cylinder 121 for guiding iron filings.

[0034] And a collection mechanism 300 provided on the outside of the housing 110 for collecting iron filings.

[0035] Among them, by setting the crushing component 120 with permanent magnet module 123, iron powder can be directionally adsorbed to the adsorption tank 122 by magnetic field, which can effectively reduce the disorderly adhesion of iron powder in the crushing chamber. At the same time, in conjunction with the vibration scraping function of scraping mechanism 200, the anti-accumulation effect is significantly improved, the risk of liner wear is reduced, and the continuous and stable operation of crusher is ensured.

[0036] Specifically, such as Figure 3 The scraping mechanism 200 also includes a vibrating rod 260 and a scraper 270 fixedly installed at the end of the vibrating rod 260 for scraping off iron filings.

[0037] The combination of the vibrating rod 260 and the scraper 270 can mechanically scrape the iron powder accumulated in the adsorption tank 122 under the drive of the micro waterproof motor 220, avoiding secondary accumulation of magnetically attracted iron powder, further optimizing the cleaning efficiency, and is especially suitable for working conditions with high iron content materials.

[0038] Furthermore, such as Figure 3 The adaptive vibration assembly 250 includes a sleeve 251 fixedly installed on the outside of the connecting plate 240, a return spring 252 fixedly installed in the inner cavity of the sleeve 251, a telescopic rod 253 movably sleeved on the outside of the return spring 252, and a sealing sleeve 254 fixedly installed on the outside of the sleeve 251. One end of the return spring 252 is fixedly connected to the inner wall of the sleeve 251, and the other end is fixedly sleeved on the outside of the telescopic rod 253 through a positioning sleeve.

[0039] The adaptive vibration component 250, through the elastic cooperation between the return spring 252 and the telescopic rod 253, enables the scraper 270 to automatically adjust the pressure when it contacts the liner, ensuring scraping force while avoiding component damage caused by rigid collisions, thus extending the service life of the device. The return spring 252 is fixedly connected to the telescopic rod 253 through the positioning sleeve, ensuring that the return spring 252 does not deviate or get stuck during vibration, maintaining stable vibration transmission efficiency, and improving the reliability and consistency of scraping action.

[0040] Better, such as Figure 4 The drive assembly 130 includes a support frame 131 fixedly mounted on the outside of the housing 110, a drive motor 132 fixedly mounted on the outside of the support frame 131, a rotating rod 133 fixedly mounted on the output end of the drive motor 132, a bevel gear 134 fixedly mounted on the end of the rotating rod 133, and a toothed ring sleeve 135 meshing with the bevel gear 134. The toothed ring sleeve 135 is located in the inner cavity of the cylinder 121 to form a crushing chamber.

[0041] The drive assembly 130 uses a bevel gear 134 and a toothed ring sleeve 135 for meshing transmission. It has a compact structure and efficient power transmission, which can drive the cylinder 121 to form a dynamic crushing chamber, and at the same time provide synchronous motion support for the magnetic field adsorption of the permanent magnet module 123.

[0042] Furthermore, such as Figure 1 The collection mechanism 300 includes a box 310 fixedly installed on the outside of the outer shell 110, a slot 320 opened in the inner cavity of the box 310, and a collection box 330 movably locked in the inner cavity of the slot 320. One side of the collection box 330 is located at the bottom of the adsorption groove 122 and extends outward to collect the falling iron filings.

[0043] The collection mechanism 300 is detachably installed with the collection box 330 via the slot 320, which facilitates quick cleaning of magnetically detached iron filings, reduces downtime for maintenance, and the extended design of the box body 310 ensures that the iron filings fall into the collection area in a directional manner, avoiding secondary pollution.

[0044] Furthermore, such as Figure 5 The supporting mechanism 100 also includes a hopper 140 fixedly installed at the bottom of the cylinder 121, a discharge pipe 150 fixedly installed at the bottom of the hopper 140, a feed pipe 160 fixedly installed at the top of the cylinder 121, and a connecting air pipe 170 fixedly installed on the outside of the outer shell 110. The end of the connecting air pipe 170 is fixedly connected to the outside of the cylinder 121 and they are interconnected.

[0045] Among them, the funnel-shaped design of the feeding hopper 140 and the discharge pipe 150 optimizes the smoothness of material discharge, and the cooperation between the feeding pipe 160 and the connecting air pipe 170 can introduce airflow to assist in cleaning, forming a multi-level anti-accumulation system of magnetic attraction, scraping, airflow assistance and centralized collection, which comprehensively improves the adaptability of the device.

[0046] During operation, iron ore enters the crushing chamber through the feed pipe 160, and the permanent magnet module 123 directionally adsorbs the iron powder into the adsorption tank 122. The drive component 130 drives the toothed ring sleeve 135 to rotate through the bevel gear 134 to achieve the crushing operation. At the same time, the micro waterproof motor 220 drives the scraper 270 to periodically scrape the adsorption tank 122 through the elastic adjustment of the adaptive vibration component 250. The removed iron filings fall into the collection box 330 through the chip discharge pipe 124. The crushed material is discharged through the feed hopper 140 and the discharge pipe 150, and the air pipe 170 is connected to assist the airflow to clean the material.

[0047] In summary, by using the permanent magnet module 123 to directionally adsorb iron powder into the adsorption tank 122, and in conjunction with the vibration scraping and adaptive adjustment functions of the scraping mechanism 200, a collaborative anti-accumulation system of magnetic attraction, scraping, and collection is formed. Its drive component 130 adopts bevel gear transmission to ensure that crushing and cleaning are synchronized, and the collection mechanism 300 realizes convenient recycling of iron filings. Combined with the airflow-assisted feeding structure, while ensuring crushing efficiency, it effectively solves the industry problem of iron ore easily adhering to the liner. It has comprehensive advantages such as thorough cleaning, low wear, and convenient maintenance, and significantly improves the operating stability and service life of the equipment under magnetic material conditions.
