Description

Technical Field

[0001] This utility model relates to the field of crushing devices, and in particular to a cutting and crushing device for limestone processing. Background Technology

[0002] In the limestone processing industry, the initial stone quarries vary considerably in size, with a significant number being quite large. To meet the demands of subsequent processing steps, these large limestone stones typically undergo primary crushing using a jaw crusher to bring them to a suitable particle size range for secondary processing.

[0003] However, a significant problem exists in the actual operation of jaw crushers. Due to the complex environment of limestone mining, the initial stone often contains a considerable amount of soil. If this soil is not effectively filtered, it will have many adverse effects on the crushing process. On the one hand, the soil containing moisture easily adheres to the stationary jaw plate under the squeezing action of the moving and stationary jaw plates. Over time, the soil accumulates, severely affecting the normal feeding of the limestone and reducing crushing efficiency. On the other hand, the soil mixed in with the crushed stone reduces the purity of the stone, adding unnecessary trouble to subsequent production processing and affecting the quality of the final product.

[0004] Currently, only through slots are provided on the discharge plate of the vibrating feeder for screening, which not only has limited filtration effect but also requires manual removal after the material has accumulated to a certain height. Therefore, developing a device that can effectively remove soil from limestone, is easy to operate, and has low energy consumption is of great significance for improving the efficiency and quality of limestone processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting and crushing device for limestone processing, which solves some of the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a cutting and crushing device for limestone processing, comprising a jaw crusher frame, a receiving platform, and a vibrating feeder. The receiving platform is fixedly installed at the rear end of the jaw crusher frame, and the vibrating feeder is installed at the upper end of the receiving platform. An eccentric shaft is rotatably installed on the jaw crusher frame, and an electromagnetic clutch is installed on the eccentric shaft near the right side. A main pulley is provided at the right end of the electromagnetic clutch. Rollers are rotatably installed on the upper end of the receiving platform near both the left and right sides. A conveyor belt is installed between the outer sides of the rollers. The vibrating feeder has uniformly distributed screening troughs at the inclined plate position. A shaped baffle is fixedly installed on the vibrating feeder near the front discharge port, and the rear end height of the shaped baffle is equal to the width of the screening trough.

[0007] Furthermore, the front end of the roller on the right side passes through the receiving platform and is fixedly sleeved with a bevel gear one. The front end of the receiving platform is rotatably mounted with a drive shaft near the upper right side. The left end of the drive shaft is fixedly sleeved with a bevel gear two, and the bevel gear two meshes with the bevel gear one.

[0008] Furthermore, a driven pulley is fixedly sleeved on the right end of the drive shaft, and a drive belt is provided between the driven pulley and the main pulley. The main pulley is connected to the driven pulley via the drive belt.

[0009] Furthermore, the conveyor belt is fitted with an inner liner, which is fixedly connected to the receiving platform.

[0010] Furthermore, the lower end of the vibrating feeder is provided with a through groove at the corresponding conveyor belt.

[0011] The advantages of this utility model are as follows: 1. The addition of a shaped baffle to the device, a simple structure, brings significant comprehensive benefits. Firstly, in terms of slag removal, the shaped baffle effectively blocks most of the soil mixed in the limestone, preventing it from falling directly into the jaw crusher. During continuous shaking, the soil will eventually fall onto the conveyor belt and be discharged, preventing moisture-containing soil from entering between the moving and stationary jaw plates. This also prevents soil from adhering to the stationary jaw plate under the squeezing action of the moving jaw plate, ensuring normal limestone feeding, improving the purity of the stone, and facilitating subsequent production processing. Secondly, in terms of equipment protection, the shaped baffle can buffer large pieces of limestone, preventing them from directly hitting the moving jaw plate under inertia, reducing the impact force on the moving jaw plate, thereby extending the service life of the equipment and reducing maintenance costs.

[0012] 2. The eccentric shaft rotation drives the electromagnetic clutch, which in turn causes the conveyor belt to operate, achieving automatic discharge of soil and slag. This design prevents the underside of the vibrating feeder from being filled with soil, ensuring that the filtration effect of the vibrating feeder is not affected, and guaranteeing the integrity and rationality of the entire technical solution. Compared with the manual removal of soil and slag, the conveyor belt discharge does not require on-site operation by personnel, improving operational safety and saving labor costs. In addition, the start and stop of the conveyor belt can be achieved by controlling the on and off state of the electromagnetic clutch. The conveyor belt does not need to run continuously and can be used flexibly according to actual conditions, effectively reducing energy consumption and improving energy utilization efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5A cutting and crushing device for limestone processing includes a jaw crusher frame 1, a receiving platform 2, and a vibrating feeder 3. The receiving platform 2 is fixedly installed at the rear end of the jaw crusher frame 1, and the vibrating feeder 3 is installed at the upper end of the receiving platform 2. An eccentric shaft 4 is rotatably installed on the jaw crusher frame 1, and an electromagnetic clutch 5 is installed on the eccentric shaft 4 near the right side. A main pulley 6 is provided at the right end of the electromagnetic clutch 5. Rollers 7 are rotatably installed on the upper end of the receiving platform 2 near both the left and right sides. A conveyor belt 13 is installed between the sides. A vibrating feeder 3 has evenly distributed screening troughs 15 at the inclined plate position. A shaped baffle 16 is fixedly installed on the vibrating feeder 3 near the front discharge port. The rear height of the shaped baffle 16 is equal to the width of the screening trough 15. The limestone is conveyed by the vibrating feeder 3 and falls into the space between the moving and stationary jaw plates within the jaw crusher frame 1 under gravity. The reciprocating oscillation of the moving jaw plate then crushes the limestone. This technology is mature and therefore... Without going into details, specifically, during the feeding process of the vibrating feeder 3, the tumbling limestone can break the soil into smaller blocks or particles under its vibration. The design of the screening trough 15 allows some of the soil mixed in with the limestone to fall onto the conveyor belt 13 through the screening trough 15 and the through trough 17. The remaining soil is blocked by the shaped baffle 16 to prevent it from falling directly into the jaw crusher. Under continuous vibration, it eventually falls onto the conveyor belt 13, thus preventing some soil containing moisture from entering between the moving and stationary jaw plates and adhering to the stationary jaw plate under the squeezing action of the moving jaw plate, affecting the feeding of the crushed limestone. At the same time, it improves the purity of the stone and provides convenience for subsequent production processing. This device can greatly improve the soil removal effect by adding the shaped baffle 16. It is simple and practical. In addition, the shaped baffle 16 can also play a certain buffering role for large pieces of limestone, preventing them from falling directly onto the moving jaw plate under inertia, thus improving the service life of the device.

[0017] Please see Figures 1-5The front end of the right roller 7 passes through the receiving platform 2 and is fixedly sleeved with a bevel gear 8. A drive shaft 9 is rotatably mounted on the front end of the receiving platform 2 near the upper right side. A bevel gear 10 is fixedly sleeved on the left end of the drive shaft 9, meshing with the bevel gear 8. A driven pulley 11 is fixedly sleeved on the right end of the drive shaft 9. A drive belt 12 is provided between the driven pulley 11 and the main pulley 6, and the main pulley 6 is connected to the driven pulley 11 via the drive belt 12. An inner liner 14 is fitted inside the conveyor belt 13, and the inner liner 14 is fixedly connected to the receiving platform 2. A through groove 17 is provided at the lower end of the vibrating feeder 3 corresponding to the conveyor belt 13. Furthermore, the rotation of the eccentric shaft 4 can also drive the electromagnetic clutch 5 to rotate. After energizing the electromagnetic clutch 5, its rotation can also drive the main pulley 6 to rotate. The rotation of the main pulley 6 can... The transmission belt 12 drives the pulley 11 to rotate, which in turn drives the transmission shaft 9 to rotate. The transmission shaft 9 then drives the bevel gear 10 to rotate, which in turn drives the bevel gear 8 to rotate. The bevel gear 8 then drives the roller 7 to rotate, thus causing the conveyor belt 13 to operate. The operation of the conveyor belt 13 removes soil and debris that falls onto it, preventing the underside of the vibrating feeder 3 from being filled with soil and affecting the filtration effect. This ensures the integrity and rationality of the technical solution. At the same time, it eliminates the need for manual cleaning, making it safer and more convenient. The start and stop of the conveyor belt 13 can be achieved by controlling the on / off state of the electromagnetic clutch 5, without the need for additional drive equipment, simplifying the process. Furthermore, the conveyor belt 13 does not need to run continuously, increasing energy consumption. It is flexible in use, and operators can use it according to the actual situation.

[0018] Working Principle: During the feeding process of the vibrating feeder 3, the tumbling limestone breaks the soil into smaller blocks or particles. The design of the screening trough 15 allows some of the soil mixed in with the limestone to fall onto the conveyor belt 13 through the screening trough 15 and the through trough 17. The remaining soil is blocked by the shaped baffle 16 to prevent it from falling directly into the jaw crusher. Under continuous vibration, it eventually falls onto the conveyor belt 13, thus preventing some moisture-containing soil from entering between the moving and stationary jaw plates and adhering to the stationary jaw plate under the squeezing action of the moving jaw plate, affecting the feeding of the crushed limestone. This also improves the purity of the stone, facilitating subsequent production processing. This device significantly improves the soil removal effect by adding the shaped baffle 16, making it simple and practical. The shaped baffle 16 also provides a certain buffering effect for large pieces of limestone, preventing them from directly hitting the moving jaw plate under inertia, thus extending the device's service life. Furthermore, the rotation of the eccentric shaft 4 can also... When the electromagnetic clutch 5 rotates, energizing it drives the main pulley 6, which in turn drives the drive belt 12 to rotate the driven pulley 11. The driven pulley 11 then drives the drive shaft 9, which in turn drives the bevel gear 10, which in turn drives the bevel gear 8, which in turn drives the roller 7. This causes the conveyor belt 13 to operate, thus discharging any soil or debris that falls onto it. This prevents the underside of the vibrating feeder 3 from becoming clogged with soil, affecting the filtration effect and ensuring the integrity and rationality of the technical solution. Furthermore, it eliminates the need for manual cleaning, making it safer and more convenient. The start and stop of the conveyor belt 13 can be controlled by adjusting the energization of the electromagnetic clutch 5, eliminating the need for additional drive equipment and simplifying the process. The conveyor belt 13 does not need to run continuously, increasing energy consumption, making it flexible and allowing operators to use it according to actual conditions.
