Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to an automatic feeding device for a cone crusher. Background Technology

[0002] A cone crusher is a type of crushing machinery suitable for raw materials in the metallurgical, construction, road building, chemical, and silicate industries. It comes in many models depending on the crushing principle and the particle size of the product. Crushers are widely used in numerous sectors including mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. During operation, a feeding device is installed at the inlet of the cone crusher to supply materials.

[0003] The prior art, such as the Chinese patent (CN209061196U), discloses an automatic feeding control system for a cone crusher, including an installation plate. A crushing component is installed on the upper end of the installation plate, and a shock-absorbing component is installed on the outside of the crushing component. This utility model has a scientific and reasonable structure, is safe and convenient to use, and is equipped with a crushing component. Through the action of the crushing chamber radar level gauge box, shock-absorbing pad, frequency converter box, distribution chamber and feed inlet, the radar level gauge detects the material level height in the material chamber in real time, controlling the material level in the mill to always be at a high level, achieving the effect of filling the feed, improving the processing effect and efficiency of the mill. The shock-absorbing component, through the action of the fixing block, shock-absorbing spring and connecting column, facilitates the absorption of the vibration generated during the operation of the crushing chamber, improving the stability of the device. Through the action of the connecting hole, shielding plate and elastic hook, it is easy to shield the shock-absorbing spring, preventing impurities from flying into the shock-absorbing spring and affecting its normal operation.

[0004] This method has the following drawbacks: First, the device lacks a screening mechanism before feeding, causing oversized materials to mix with smaller materials and enter the crusher. This results in smaller materials not being crushed, leading to poor crushing efficiency. Second, the device can experience material accumulation and blockage when material is poured into the feed inlet all at once. This requires manual clearing by the operator, which is time-consuming and labor-intensive. Furthermore, the device automatically controls the material position and stops feeding when material accumulates at the feed inlet, requiring the feeding conveyor to be opened and closed in coordination, making operation cumbersome. Third, the lack of a uniform feeding device before the material enters the crushing mechanism results in low crushing efficiency.

[0005] Therefore, this paper provides an automatic feeding device for a cone crusher. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0025] like Figures 1 to 6 As shown:

[0026] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. The device does not have a screening mechanism for the material before feeding, which causes some oversized materials to be mixed with small materials and enter the crusher. This results in the small materials not being crushed, leading to poor crushing effect of the device; 2. The device can cause material accumulation and blockage when the material is poured into the feed inlet all at once. This requires the operator to manually clear the blockage, which is time-consuming and labor-intensive. Moreover, when the material accumulates at the feed inlet, the device will automatically control the material position and stop feeding, which requires the feeding conveyor to be opened and closed, making the operation cumbersome; 3. There is no uniform feeding device before the material enters the crushing mechanism, resulting in low crushing efficiency;

[0027] Therefore, the inventor provides an automatic feeding device for a cone crusher, including a crusher body 1 and an automatic feeding device. The automatic feeding device is located above the crusher body 1 and is electrically connected to a control cabinet (not shown in the figure). The automatic feeding device also includes a feeding cylinder 2, a screening feeding device 3, and a uniform feeding device 4. The feeding cylinder 2 is located above the crusher inlet, the uniform feeding device 4 is located inside the feeding cylinder 2 above the crusher body 1, and the screening feeding device 3 is located above the uniform feeding device 4.

[0028] Using the above scheme, during the crushing operation, the material enters from above the feed cylinder 2 and is screened in the screening and feeding device 3. Material that does not meet the size requirements is blocked by the screening and feeding device 3 in the feed cylinder 2 above the screening and feeding device 3. Material that meets the size requirements comes down to the uniform feeding device 4. After being dispersed by the uniform feeding device 4, it falls evenly down into the crusher body 1 to complete the crushing. Example 2

[0029] like Figures 1 to 6 As shown:

[0030] Furthermore, the screening and feeding device 3 also includes a drive motor a5, a vibration mechanism 6, a rotating shaft a7, a rotating shaft b8, a spiral screen plate 9, a return port 10, an electric valve 11, and a conveyor belt device 12. The drive motor a5 is located on the right side of the feeding cylinder 2, the rotating shaft a7 is located on the output end on the left side of the drive motor a5, the rotating shaft b8 is slidably sleeved on the left side of the rotating shaft a7, the vibration mechanism 6 is located at the connection between the rotating shaft a7 and the rotating shaft b8, the spiral screen plate 9 is located on the outer side of the upper part of the rotating shaft b8, the return port 10 is located on the upper right side of the spiral screen plate 9, the electric valve 11 is located on the return port 10, and the conveyor belt device 12 is located below the return port 10.

[0031] Furthermore, the vibration mechanism 6 also includes a transmission rod 13, a telescopic hole 14, a return spring 15, a mounting plate 16, and a slide groove 17. The transmission rod 13 is respectively located on the lower left side of the rotating shaft a7, and the telescopic hole 14 is respectively located on the upper right side of the rotating shaft b8. The front end of the transmission rod 13 is slidably connected in the telescopic hole 14. The return spring 15 is located in the telescopic hole 14 and is located on the lower left side of the transmission rod 13. The mounting plate 16 is located on the lower left side of the feeding cylinder 2 of the rotating shaft b8 and is rotatably connected to the lower end of the rotating shaft b8. The inclined slide groove 17 is located on the inner side of the connection between the mounting plate 16 and the rotating shaft b8.

[0032] Furthermore, a limiting block 18 that is slidably connected to the slide groove 17 is provided on the lower side of the rotating shaft b8;

[0033] Furthermore, the surface of the spiral screen plate 9 is provided with screen holes 19;

[0034] When the material enters the feeding cylinder 2, the drive motor a5 drives the rotating shaft a7 to rotate. The rotating shaft a7 drives the rotating shaft b8 to rotate through the transmission rod 13. The rotating shaft b8 drives the spiral screen plate 9 to rotate in the opposite direction of the blade rotation, causing the spiral screen plate 9 to push out unqualified material. The qualified material will fall into the uniform feeding device 4 through the screen holes 19 on the surface of the spiral screen plate 9. During this process, the rotating shaft b8 rotates on the mounting plate 16, causing the limiting block 18 to slide in the inclined slide groove 17. This allows the rotating shaft b8 to be pushed up and down inside the rotating shaft a7 during rotation. The return spring 15 below the transmission rod 13... The transmission rod 13 can reciprocate within the telescopic hole 14 while providing elasticity to reset it. This allows unqualified materials to be pushed upwards during the screening process. The vibration mechanism 6 can effectively prevent material blockage and accumulation above the spiral screen plate 9, and simultaneously push the screened unqualified materials upwards into the return port 10. After the device has been running for a period of time, the electric valve 11 can be opened through the control cabinet to discharge the accumulated unqualified materials onto the conveyor belt device 12 for recycling and crushing. This allows for the early screening of materials that do not meet the size requirements, preventing uneven material entering the crusher from causing poor crushing results. Example 3

[0035] like Figures 1 to 6 As shown:

[0036] Furthermore, the uniform feeding device 4 also includes a drive motor b20, a bevel gear a21, a bevel gear b22, a rotating shaft c23, a spiral feed plate 24, a stirring rod 25, and a diverter 26. The drive motor b20 is located on the front side of the feed inlet of the crusher body 1. The output end of the drive motor b20 is provided with a bevel gear a21. The bevel gear b22 is located above the bevel gear a21 and meshes with the bevel gear a21. The rotating shaft c23 is located above the bevel gear b22. The spiral feed plate 24 is located on the outer side of the lower part of the rotating shaft c23. The stirring rod 25 is located on the outer side of the upper part of the rotating shaft c23. The diverter 26 is located below the rotating shaft c23.

[0037] Furthermore, the output end of the drive motor b20 passes through the interior of the splitter frame 26 and is connected to the bevel gear a21;

[0038] The screened material enters the uniform feeding device 4. The drive motor b20 drives the bevel gear a21, which in turn drives the bevel gear b22 to rotate the shaft c23. The shaft c23 drives the spiral feed plate 24 to convey the material downwards. After being diverted by the diverter 26, the material falls evenly into the crusher body 1 for crushing. At the same time, by observing the discharge status below the crusher body 1, the speed of the spiral feed plate 24 can be controlled by controlling the speed of the drive motor b20 through the control cabinet, thereby controlling the feeding speed. The material accumulated above the spiral feed plate 24 flows downwards under the agitation of the stirring rod 25. The rotation of the stirring rod 25 prevents the material from accumulating and clogging above the spiral feed plate 24. In this way, while preventing material blockage, the material can be evenly supplied to the crusher, simplifying the operation steps and improving the crushing efficiency.

[0039] In summary, this device is equipped with a screening and feeding device 3, which uses a vibration mechanism 6 and a spiral screen plate 9 to pre-screen materials that do not meet the size requirements, preventing uneven material entering the crusher from causing poor crushing effect and ensuring the crushing effect of the crusher; it is also equipped with a uniform feeding device 4, which uses a stirring rod 25 to prevent material accumulation and blockage, while the spiral feed plate 24 and the diverter 26 can control the material flow rate, so that the material falls evenly into the crusher body 1 for crushing, simplifying the operation steps and improving the crushing efficiency.

[0040] The working principle of this utility model:

[0041] During the crushing operation, the material enters from above the feed cylinder 2. After the material enters the feed cylinder 2, the drive motor a5 drives the rotating shaft a7 to rotate. The rotating shaft a7 drives the rotating shaft b8 to rotate through the transmission rod 13. The rotating shaft b8 drives the spiral screen plate 9 to rotate in the opposite direction of the blade rotation, causing the spiral screen plate 9 to push out unqualified material. Qualified material will fall downwards through the screen holes 19 on the surface of the spiral screen plate 9 into the uniform feeding device 4. During this process, the rotating shaft b8 rotates on the mounting plate 16, causing the limiting block 18 to slide in the inclined slide groove 17. This allows the rotating shaft b8 to be pushed up and down inside the rotating shaft a7 during rotation. The area below the transmission rod 13... The return spring 15 can provide elastic force to reset the transmission rod 13 while it reciprocates within the telescopic hole 14. In this way, during the screening process, unqualified materials can be pushed upwards while screening the materials. The vibration mechanism 6 can effectively prevent materials from clogging and accumulating above the spiral screen plate 9 through vibration. At the same time, it pushes the screened unqualified materials upwards into the return port 10. After the device has been running for a period of time, the electric valve 11 can be opened through the control cabinet to discharge the accumulated unqualified materials onto the conveyor belt device 12 for recycling and crushing. This way, materials that are not up to size are screened out in advance, preventing uneven material entering the crusher from causing poor crushing effect.

[0042] After screening, the material enters the uniform feeding device 4. The drive motor b20 drives the bevel gear a21, which in turn drives the bevel gear b22 to rotate the shaft c23. The shaft c23 drives the spiral feed plate 24 to convey the material downwards. After being diverted by the diverter 26, the material falls evenly into the crusher body 1 for crushing. At the same time, by observing the discharge status below the crusher body 1, the speed of the drive motor b20 can be controlled by the control cabinet to control the speed of the spiral feed plate 24, thereby controlling the feeding speed. The material accumulated above the spiral feed plate 24 flows downwards under the stirring of the stirring rod 25. The rotation of the stirring rod 25 prevents the material from accumulating and clogging above the spiral feed plate 24. In this way, while preventing material blockage, the material can be evenly supplied to the crusher, simplifying the operation steps and improving the crushing efficiency.

[0043] This concludes the description of the working principle of the device.
