Description

Technical Field

[0001] This application relates to the field of material feeding devices, and in particular to a disc feeder with good sealing performance. Background Technology

[0002] A disc feeder, also known as a disc ore feeder, is a type of ore processing feeding equipment, typically consisting of a drive unit and a feeder body. The drive unit usually includes a driven wheel fixedly connected to the rotating shaft of the disc in the feeder body. A drive wheel meshes with one side of the driven wheel. The motor drives the drive wheel, causing the driven wheel and the disc to rotate. At this time, the material in the feeder's disc falls into the hopper of the feeder body through an opening on one side of the disc as the disc rotates, completing the feeding process.

[0003] Both the driving wheel and the driven wheel are located in the same support cylinder that supports the disc. A mounting cover is installed on the rotating shaft to cover the support cylinder. During installation, the lower side of the mounting cover abuts against the upper wall of the support cylinder. Furthermore, both the driving wheel and the driven wheel are lubricated with thin oil during use to reduce friction generated when they mesh.

[0004] In related technologies, the lower side of the mounting cover abuts against the upper wall of the support cylinder, and the gap between the mounting cover and the support cylinder is connected to the inside of the support cylinder. This can easily cause dust to enter the support cylinder along the gap between the mounting cover and the support frame and contaminate the thin oil, thereby causing wear on the drive wheel and the driven wheel. Utility Model Content

[0005] To reduce the possibility of dust entering the support cylinder and extend the service life of the drive wheel and driven wheel, this application provides a disc feeder with good sealing effect.

[0006] The disc feeder with good sealing effect provided in this application adopts the following technical solution:

[0007] A disc feeder with good sealing performance includes a feeder body and a frame. A disc is disposed inside the feeder body. A drive mechanism for driving the disc to rotate is disposed below the feeder body. A fixed shaft that is rotatably connected to the bottom end of the disc is fixedly connected to the frame. The drive mechanism includes a gear ring that is coaxially fixed to the outer wall of the fixed shaft. A gear meshes with one side of the gear ring. A drive motor for driving the gear to rotate is mounted on the frame. A support cylinder is fixedly connected to the frame. The gear ring and the gear are installed inside the support cylinder. The upper end of the support cylinder is open. A mounting cover for covering the support cylinder is connected to the fixed shaft. An oil-immersed packing is installed between the mounting cover and the support cylinder.

[0008] By adopting the above technical solution, the drive motor drives the gear and gear ring to rotate, and the rotation of the gear ring drives the disc to rotate, thereby completing the material feeding. The disc feeder effectively reduces the occurrence of dust and impurities entering the drive mechanism by installing the gear ring and gear inside the support cylinder and using oil-immersed packing for sealing, which helps to extend the service life of the drive wheel and driven wheel.

[0009] Preferably, an oil level indicator is fixedly connected to the side wall of the support cylinder.

[0010] By adopting the above technical solution, the effect of fixing the oil level indicator on the side wall of the support cylinder is to facilitate the observation of the lubricating oil level inside the support cylinder, ensuring that the gear ring and gears operate under suitable lubrication conditions, thereby improving the stability and service life of the transmission system.

[0011] Preferably, the outer side of the feeder body is covered with a pressure-reducing sleeve, and the lower end of the pressure-reducing sleeve is fixedly connected to the mounting cover by fasteners.

[0012] By adopting the above technical solution, the pressure-reducing sleeve can effectively reduce the impact of external air pressure fluctuations on the rotation of the internal disc, thereby improving the stability of equipment operation. The pressure-reducing sleeve and the mounting cover are fixedly connected by fasteners, making the overall structure more stable, facilitating installation and disassembly, and enhancing sealing performance, thus reducing the risk of material leakage.

[0013] Preferably, the pressure-reducing sleeve includes an upper cover and a lower cover arranged vertically, the upper cover and the lower cover are fixedly connected, and a sealing cover is fixedly connected at the connection between the upper cover and the lower cover.

[0014] By adopting the above technical solution, the pressure-reducing sleeve of the disc feeder consists of an upper cover and a lower cover, which are fixedly connected to form an integral structure. A sealing cover is added at the connection point, effectively enhancing the sealing performance of the pressure-reducing sleeve, reducing material leakage or the entry of external impurities, and improving the overall reliability of the equipment. Furthermore, this split design facilitates installation and maintenance, reducing operational difficulty.

[0015] Preferably, a speed reducer is fixedly connected to the frame, the output shaft of the speed reducer passes through the support cylinder and is fixedly coaxially with the gear, and the input shaft of the speed reducer is fixedly connected to the output shaft of the drive motor.

[0016] By adopting the above technical solution, the speed reducer can lower the speed of the drive motor and increase the torque, thereby ensuring the stability of gear rotation and further improving the working reliability of the disc feeder. The output shaft of the speed reducer is coaxially and fixedly connected to the gear, making power transmission more direct and efficient, and reducing energy loss. At the same time, the input shaft of the speed reducer is fixedly connected to the output shaft of the drive motor, simplifying the transmission structure and improving the compactness and stability of the overall device.

[0017] Preferably, the drive motor is located on one side of the feeder body, and a universal coupling is provided between the drive motor and the reducer. One end of the universal coupling is fixedly connected to the input shaft of the reducer, and the other end is fixedly connected to the output shaft of the drive motor.

[0018] By adopting the above technical solution, a universal coupling is installed between the drive motor and the reducer, allowing the drive motor to be flexibly positioned on one side of the feeder body without strict alignment. This improves the flexibility and convenience of equipment installation, reduces the obstruction of the drive motor by the feeder body, and facilitates drive motor maintenance. Simultaneously, the universal coupling effectively transmits torque, ensuring stable and reliable power transmission between the drive motor and the reducer, and reducing the failure rate of the transmission system.

[0019] Preferably, the universal coupling is covered with a coupling guard, which is fixedly connected to the frame.

[0020] By adopting the above technical solution, the coupling cover can effectively protect the universal coupling, reducing the occurrence of external impurities or foreign objects entering the universal coupling, thereby improving the reliability of equipment operation. At the same time, the coupling cover is fixedly connected to the frame, ensuring structural stability and safety, and preventing the coupling cover from loosening or falling off due to vibration or external forces.

[0021] Preferably, the gear ring is fastened to the fixed shaft by bolts.

[0022] By adopting the above technical solution, the gear ring and the fixed shaft are fastened together by bolts, making the connection between the two more stable and reliable, facilitating disassembly and maintenance, and ensuring stability during transmission.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By installing oil-immersed packing between the support cylinder and the mounting cover, the sealing performance of the disc feeder is effectively enhanced, reducing the possibility of dust entering the support cylinder and extending the service life of the drive wheel and driven wheel;

[0025] 2. The gear ring and gear are installed inside the support cylinder and driven by the drive motor and reducer, making the transmission structure more compact;

[0026] 3. It reduces the obstruction of the drive motor by the feeder body, making it easier to maintain the drive motor. Attached Figure Description

The drive mechanism 3 drives the disc 21 to rotate, thereby completing the feeding operation of the feeder.

[0033] Reference Figure 1 and Figure 3 The bottom end of the disc 21 is fixedly connected to a fixed shaft 22 that is rotatably connected to the frame 1. The drive mechanism 3 includes a gear ring 31 that is fastened to the outer wall of the fixed shaft 22 by bolts. The gear ring 31 is coaxially arranged with the fixed shaft 22. A gear 32 meshes with one side of the gear ring 31 and is rotatably connected to the frame 1.

[0034] The feeder body 2 is covered by a pressure-reducing sleeve 4. The lower end of the pressure-reducing sleeve 4 is provided with a support cylinder 5 that is fixedly connected to the frame 1.

The installation cover 6 is fixedly connected to the bottom end of the pressure-reducing sleeve 4. The gear ring 31 and the gear 32 are both installed inside the support cylinder 5. The upper end of the installation cover 6 is provided with an annular groove, and an oil-immersed packing 51 is installed in the annular groove. The oil-immersed packing 51 is tightly pressed against the bottom surface of the installation cover 6.

[0035] The oil-immersed packing 51 effectively prevents dust and impurities from entering the working area of ​​the gear ring 31 and gear 32, while maintaining the sealing of the lubricating oil inside the support cylinder 5. The oil-immersed packing 51 can be made of natural rubber or synthetic rubber according to actual needs to adapt to different working environments.

[0039] The pressure-reducing sleeve 4 includes an upper cover 41 and a lower cover 42 arranged vertically, which are fastened together by bolts and nuts. A sealing cover 43 is fixedly connected between the upper cover 41 and the lower cover 42, covering the connection between the upper cover 41 and the lower cover 42.

[0040] The implementation principle of a disc feeder with good sealing effect according to an embodiment of this application is as follows: The drive motor 34 is started, and the output shaft of the drive motor 34 drives the universal coupling 35 to rotate. Subsequently, the reducer 33 drives the gear 32 and gear ring 31 to rotate, which in turn drives the fixed shaft 22 and the disc 21 to rotate. By placing the drive mechanism 3 inside the support cylinder 5, and cooperating with structures such as the oil-immersed packing 51 and the pressure-reducing sleeve 4, effective protection of key transmission components is achieved, significantly improving the sealing performance of the disc feeder.
