Technical Field
[0001] This utility model belongs to the field of ball mill technology, and in particular relates to a grinding jar fixing device for a ball mill. Background Technology
[0002] In the application of ball mills, the stable fixing of the grinding jar is the key to ensuring grinding efficiency and safe operation of the equipment. Traditional methods of fixing the grinding jar mostly rely on fasteners such as bolts and nuts, which are tightened to fix the grinding jar in the inner cavity of the ball mill. However, this fixing method has many shortcomings, especially under high-speed operation and high-load working conditions, the fixing effect of the grinding jar is often difficult to guarantee.
[0003] Traditional grinding jar fixing methods typically involve placing a layer of padding on the top and bottom of the jar, and then tightening the top layer with screws. This traditional fixing method is cumbersome, requiring multiple installations and disassemblies, which not only increases the difficulty of operation but also reduces work efficiency. Furthermore, the use of multiple layers of padding increases the overall height, making the grinding jar more prone to loosening during high-speed operation, thus affecting the stability of the ball mill and the grinding effect. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the prior art by providing a grinding jar fixing device for a ball mill.
[0005] To achieve the above objectives, the utility model employs the following technical solution: a grinding jar fixing device for a ball mill, comprising a ball mill body, wherein a plurality of grinding jar seats are installed in the inner cavity of the ball mill body, a pair of connecting seats are respectively installed on the outer periphery of the plurality of grinding jar seats, a fixing plate is respectively installed on the upper surface of the pair of connecting seats, a toothed plate is respectively installed on the opposite side of the pair of fixing plates, a pressure plate is installed between the pair of fixing plates, a cavity structure is respectively opened at both ends of the pressure plate, a locking block that engages with the toothed plate is respectively installed on the inner side of the pair of cavity structures, a return spring is installed between the locking block and the cavity structure, and a pair of gripping plates respectively connected to the locking block are installed on the surface of the pressure plate.
[0006] By adopting the above technical solution, the grinding jar is quickly and stably fixed through the snap-fit structure of the toothed plate and the locking block. The addition of the return spring allows the locking block to automatically reset under external force, maintaining a tight snap-fit with the toothed plate, thereby improving the reliability and stability of the fixation. The design of the grip plate facilitates the installation and disassembly work of the operator and improves work efficiency.
[0007] Optionally, the pair of fixing plates are rectangular, and a pair of positioning grooves are respectively provided on opposite sides of the pair of fixing plates.
[0008] By adopting the above technical solution, the rectangular shape of the fixing plate makes the device structure more regular, which is convenient for installation and positioning. The design of the positioning groove can cooperate with the directional seats at both ends of the pressure plate to further improve the stability and accuracy of the grinding jar fixing.
[0009] Optionally, the surface of the fixing plate is provided with a mounting groove for mounting the toothed plate, and the surface of the toothed plate is at the same horizontal plane as the surface of the fixing plate.
[0010] By adopting the above technical solution, the design of the mounting groove allows the toothed plate to be securely mounted on the fixed plate, and the surface of the toothed plate is flush with the surface of the fixed plate, avoiding installation errors and safety hazards caused by uneven surfaces.
[0011] Optionally, a pair of directional seats are installed at each end of the pressure plate, and the pair of directional seats are located in a pair of directional grooves.
[0012] By adopting the above technical solution, the cooperation between the directional seat and the positioning groove can ensure the correct position of the pressure plate during the installation process, preventing poor fixing effect due to position deviation. At the same time, this design also improves the overall stability and safety of the grinding jar fixing.
[0013] Optionally, an anti-slip pad is installed on the side of the pressure plate near the grinding pot seat.
[0014] By adopting the above technical solution, the addition of anti-slip pads can increase the friction between the pressure plate and the grinding jar seat, preventing the grinding jar from sliding or displacing during high-speed operation, thereby improving the reliability and safety of the grinding jar fixation.
[0015] Optionally, the cavity structure includes a first movable groove and a second movable groove connected to the first movable groove, with a limiting step provided between the first movable groove and the second movable groove.
[0016] By adopting the above technical solution, the detailed design of the cavity structure enables the card block to move and reset stably within it.
[0017] Optionally, a movable column is installed at one end of the card block inside the cavity structure, and a connecting rod is installed at the other end of the movable column. The connecting rod is connected to the gripping plate, and a slide rail connected to the second movable groove is opened on the surface of the pressure plate. The connecting rod is located in the slide rail.
[0018] By adopting the above technical solution, the design of the movable column and connecting rod enables the gripping plate to drive the locking block to move within the cavity structure, thereby realizing the rapid installation and disassembly of the grinding jar.

Therefore, they should not be construed as limitations on this utility model.
[0032] like Figure 1 As shown in Figure 4, the specific solution of the embodiment is as follows: A grinding jar fixing device for a ball mill includes a ball mill body 1. The ball mill body 1 serves as the basic structure of the entire device and provides the installation and operating environment for the grinding jar fixing device. Its inner cavity is designed to accommodate the grinding jar seat 2 and the grinding jar, which is the main place for material grinding. A control device is installed on the ball mill body 1 to control the operation of the entire ball mill body 1. Several grinding jar seats 2 are installed in the inner cavity of the ball mill body 1. The grinding jar seats 2 are installed in the inner cavity of the ball mill body 1 to support and position the grinding jar. The number of seats is determined according to the specifications of the ball mill and the grinding requirements to ensure that the grinding jar can be uniformly stressed during the grinding process and improve the grinding efficiency.
[0033] A pair of connecting seats 3 are respectively installed on the outer periphery of several of the grinding jar seats 2. The connecting seats 3 are installed on the outer periphery of the grinding jar seats 2 and are used to fix and connect the fixing plates 4. They provide a stable connection between the fixing plates 4 and the grinding jar seats 2, ensuring the stability of the entire fixing device. The side of the connecting seat 3 that contacts the grinding jar seats 2 is an arc-shaped surface. The upper surface of the pair of connecting seats 3 is respectively installed with fixing plates 4. The pair of fixing plates 4 are rectangular. The fixing plates 4 are designed to install toothed plates 5 and provide support for pressure plates 6. The rectangular shape makes the fixing plates 4 easy to install and position, while increasing the stability of the structure.
[0034] A pair of positioning grooves 401 are respectively provided on opposite sides of the pair of fixed plates 4. The positioning grooves 401 are provided on opposite sides of the fixed plates 4 and are used to cooperate with the directional seats 601 at both ends of the pressure plate 6. This design ensures the correct position of the pressure plate 6 during installation and prevents poor fixing effect due to position deviation. A toothed plate 5 is respectively installed on opposite sides of the pair of fixed plates 4. The toothed plate 5 is installed in the mounting groove 402 on the surface of the fixed plate 4. Its surface is at the same level as the surface of the fixed plate 4. The trapezoidal groove on the toothed plate 5 is used to cooperate with the locking block 8 to achieve quick and stable fixing of the grinding jar. The surface of the fixed plate 4 is provided with the mounting groove 402 for the toothed plate 5 to be installed. The surface of the toothed plate 5 is at the same level as the surface of the fixed plate 4. The mounting groove 402 is provided on the surface of the fixed plate 4 for the toothed plate 5 to be installed. This design allows the toothed plate 5 to be stably installed on the fixed plate 4 and avoids safety hazards caused by improper installation.
[0035] A pressure plate 6 is installed between a pair of fixed plates 4. A pair of directional seats 601 are installed at both ends of the pressure plate 6. The design of the directional seats 601 ensures the correct position of the pressure plate 6 during installation, improving the stability and accuracy of the grinding jar fixation. The pair of directional seats 601 are located in a pair of directional grooves. An anti-slip pad 602 is installed on the side of the pressure plate 6 near the grinding jar seat 2. The anti-slip pad 602 is used to increase the friction between the pressure plate 6 and the grinding jar seat 2. This design effectively prevents the grinding jar from sliding or displacing during high-speed operation, improving the reliability of the fixation. The pressure plate 6 is installed between the fixed plates 4 to press and fix the grinding jar. The directional seats 601 installed at both ends cooperate with the positioning grooves 401 to ensure the correct position of the pressure plate 6. The anti-slip pad 602 installed on the side of the pressure plate 6 near the grinding jar seat 2 increases the friction between the pressure plate 6 and the grinding jar seat 2, preventing the grinding jar from sliding or displacing during high-speed operation.
[0036] The pressure plate 6 has cavity structures 7 at both ends. Each cavity structure 7 includes a first movable groove 701 and a second movable groove 702 connected to the first movable groove 701. A limiting step 703 is provided between the first movable groove 701 and the second movable groove 702, which provides space for the installation and movement of the locking block 8. The inner sides of each pair of cavity structures 7 are respectively equipped with locking blocks 8 that engage with the toothed plate 5. The design of the locking block 8 enables the grinding jar to be quickly and stably fixed. At the same time, the design of the movable column 801 and the connecting rod 802 enables the gripping plate 10 to drive the locking block 8 to move within the cavity structure 7, thereby enabling the grinding jar to be quickly installed and disassembled.
[0037] The locking block 8 is equipped with a movable column 801 at one end inside the cavity structure 7. The movable column 801 connects the locking block 8 and the connecting rod 802. This allows the locking block 8 to move under external force while maintaining a tight engagement with the toothed plate 5. The other end of the movable column 801 is equipped with the connecting rod 802, which transmits the force exerted by the operator on the grip plate 10, allowing the locking block 8 to move within the cavity structure 7, thus enabling quick installation and disassembly of the grinding jar. The connecting rod 802 is connected to the grip plate 10. The surface of the pressure plate 6 has a slide rail 603 that connects to the second movable groove 702. The connecting rod 802 is located within the slide rail 603. The locking block 8 is trapezoidal in shape, and the tooth grooves on the toothed plate 5 are trapezoidal grooves that cooperate with the locking block 8.
[0038] A return spring 9 is installed between the locking block 8 and the cavity structure 7. The return spring 9 allows the locking block 8 to automatically reset under external force and maintain a tight engagement with the toothed plate 5, improving the reliability and stability of the fixation. One end of the return spring 9 is connected to the limiting step 703. A pair of gripping plates 10, each connected to the locking block 8, are installed on the surface of the pressure plate 6. Rubber pads 1001 are installed on the opposite sides of the pair of gripping plates 10. The gripping plates 10 are installed on the surface of the pressure plate 6 and connected to the locking block 8. The operator can easily move the locking block 8 within the cavity structure 7 using the gripping plates 10, enabling quick installation and removal of the grinding jar. The rubber pads 1001 installed on the opposite sides of the gripping plates 10 increase the comfort of the grip and prevent safety hazards caused by improper gripping.
