Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically a multifunctional ball mill. Background Technology

[0002] Ball mills are grinding equipment widely used in ore processing, building materials, chemical industry, metallurgy and other fields. They mainly crush materials to the required particle size through the impact and grinding action of grinding media (steel balls, steel segments, etc.). Small ball mills are also used in laboratories to grind samples to facilitate subsequent experiments.

[0003] Currently, most small ball mills directly feed grinding balls and samples into the grinding device and grind them by rotation. Since the grinding chamber is usually fixedly connected to the grinding device, it is inconvenient to unload the material, making it cumbersome for the experimenters to remove the material and requiring more time, resulting in low loading and unloading efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional ball mill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional ball mill, comprising: a ball mill body; a rotating table rotatably mounted on the ball mill body; a drive motor fixedly mounted inside the ball mill body, the output end of the drive motor being connected to the circular part of the rotating table; a plurality of mounting seats rotatably mounted on the rotating table, the plurality of mounting seats being evenly distributed on the rotating table, each mounting seat having a storage box inserted inside, the storage box having a sealing cover for sealing inside; a support frame fixedly mounted on the mounting seats, the support frame having an adjusting block; an adjusting screw threaded inside the adjusting block, the bottom end of the adjusting screw having a pressure block rotatably mounted thereon, the adjusting screw being configured such that when it rotates, the pressure block presses against the surface of the sealing cover, so that the storage box is more stable when rotating.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1

[0023] Referring to 1-4, in this embodiment, a multifunctional ball mill includes: a ball mill body 1; a rotating table 2 rotatably mounted on the ball mill body 1; a drive motor 3 fixedly mounted inside the ball mill body 1, with its output end connected to the circular part of the rotating table 2; several mounting seats 4 rotatably mounted on the rotating table 2, the mounting seats 4 being evenly distributed on the rotating table 2, each mounting seat 4 having a storage box 7 inserted inside, and the storage box 7 having a sealing cover 8 for sealing; a support frame 9 fixedly mounted on the mounting seats 4, with an adjusting block 11 mounted on the support frame 9; an adjusting screw 12 threaded inside the adjusting block 11, with a pressure block 13 rotatably mounted at the bottom end of the adjusting screw 12, wherein when the adjusting screw 12 is rotated, the pressure block 13 presses against the surface of the sealing cover 8 to make the storage box 7 more stable during rotation; a support base 24 fixedly mounted on the ball mill body 1, the surface of the rotating table 2 being rotatably mounted inside the support base 24; and a fixed gear 5. The fixed gear 5 is fixedly mounted on the ball mill body 1, with its shaft aligned with that of the drive motor 3. Several planetary gears 6 are fixedly mounted on the bottom of the mounting base 4, with their outer surfaces meshing with the outer surfaces of the fixed gear 5. A support ring 25 is fixedly mounted on the bottom of the rotating table 2, with its outer surface rotatably mounted inside the support base 24. Several ball bearings 26 are rotatably mounted on the support ring 25, with their surfaces rolling inside the support base 24. The rotating table 2 rotates under the action of the drive motor 3, causing the steel balls in the storage box 7 to deviate under centrifugal force. Through the cooperation of the fixed gear 5 and the planetary gears 6, the storage box 7 rotates during rotation, allowing the sample to fully rub against the grinding balls, achieving a grinding effect. The pressure block 13 fixes the sealing cover 8, eliminating the need for the sealing cover 8 to be fixed to the storage box 7, facilitating material feeding and improving grinding efficiency.

[0024] Example 2

[0025] Referring to 3-5, in this embodiment, a multifunctional ball mill includes: an extension rod 16, fixedly disposed on both sides of an adjusting block 11; a mounting through hole 10, penetrating the support frame 9; a retaining sleeve 17, sleeved on the extension rod 16, with F-shaped grooves 18 symmetrically formed on the inner surface of the retaining sleeve 17, and limiting grooves 19 formed on the two side ends of the F-shaped grooves 18; protrusions 20, symmetrically disposed on the extension rod 16, with the outer surface of the protrusions 20 slidably disposed inside the F-shaped grooves 18; a compression spring 21, fixedly disposed inside the retaining sleeve 17, with the other end of the compression spring 21 pressing against the end face of the extension rod 16, and when the retaining sleeve 17 is in the extended state, it is inserted into the mounting through hole 10; and a sealing sleeve 22, fixedly disposed on the end face of the retaining sleeve 17. The inner surface of the sealing sleeve 22 is slidably disposed with the surface of the extension rod 16; the stop block 23 is fixedly disposed on the inner surface of the sealing sleeve 22, and one end of the stop block 23 is inserted into the F-shaped groove 18; the positioning groove 14 is opened at the top of the sealing cover 8; the limiting block 15 is fixedly disposed on the sealing cover 8, and the outer surface of the limiting block 15 is inserted into the inside of the storage box 7. By setting the protrusion 20, the sleeve 17 can be limited by the limiting groove 19. By setting the F-shaped groove 18, two positions can be adjusted so that the sleeve 17 can be fixed in the two positions of extension and retraction, which is convenient for disassembly and installation. By setting the stop block 23, the position of the protrusion 20 can be limited to ensure that the protrusion 20 can accurately enter the transverse groove of the F-shaped groove 18.

[0026] This utility model provides a multifunctional ball mill, the specific working principle of which is as follows:

[0027] During sample grinding, the operator places the steel balls and sample into the storage box 7 and closes it with the sealing cover 8. Then, after placing it into the mounting base 4, the operator places the adjusting block 11 between the support frame 9 and aligns the two retaining sleeves 17 with the mounting through holes 10. The retaining sleeve 17 is then rotated to disengage from the limiting groove 19 and the transverse groove of the F-shaped groove 18, releasing the restriction on the pressure spring 21. Under the force of the pressure spring 21, the retaining sleeve 17 extends and enters the mounting through hole 10. The retaining sleeve 17 is then rotated to enter the other limiting groove 19, where it is limited by the pressure spring 21. The adjusting screw 12 is then rotated to drive the pressure block 13 to press the sealing cover 8 on the storage box 7. After the storage box 7 is fixed, the drive motor 3 is started. The motor 3 drives the rotating table 2 to rotate. During the rotation of the rotating table 2, the planetary gear 6 rotates due to its meshing with the fixed gear 5, causing the storage box 7 to rotate along with the rotating table 2, ensuring that the sample is fully ground. After the sample is ground, the operator presses the sleeve 17, causing the sleeve 17 to penetrate into the extension rod 16. After the protrusion 20 limits the sleeve 17, the operator rotates the sleeve 17, causing the protrusion 20 to enter the limiting groove 19. Under the action of the pressure spring 21, the protrusion 20 is stably placed inside the limiting groove 19. Then, the adjusting block 11 can be directly removed from the support frame 9. After removal, the operator can directly take out the storage box 7 and open the sealing cover 8 to take out the material.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
