[0021] 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.

[0022] Example:

[0023] Please see Figure 1 - Figure 4 This embodiment of a quick-installation fixed planetary ball mill includes a housing 1 and a grinding jar 7. The housing 1 has a hollow structure. A rotary motor 2 is fixedly installed inside the housing 1. The rotary motor 2 is located at the bottom of the housing 1. A rotary shaft 3 is fixedly connected to the output end of the rotary motor 2. A drive gear column 4 is fixedly installed at the upper end of the rotary shaft 3. The drive gear column 4 extends to the outside of the housing 1. A revolution stage 5 is rotatably installed inside the housing 1. The revolution stage 5 is located above the rotary motor 2. Several rotation stages 6 are rotatably installed at the upper end of the revolution stage 5. A gear ring 15 is fixedly installed on the inner wall of the housing 1. The gear ring 15 is located outside the rotation stages 6. The grinding jar 7 is rotatably installed above the rotation stages 6.

[0024] When the rotary motor 2 starts rotating, the rotary shaft 3 connected to its output end also starts rotating, simultaneously driving the drive gear column 4 at the upper end of the rotary shaft 3 to rotate. The rotating drive gear column 4 drives the revolution stage 5 to rotate, and the rotary table 6 at the upper end of the revolution stage 5 revolves with the revolution stage 5. At the same time, the rotary table 6 itself is driven by the drive gear column 4 to rotate in conjunction with the limiting gear ring 15. The grinding jar 7 above the rotary table 6 also revolves and rotates with the rotary table 6, forming two types of motion for the grinding jar 7. At the same time, the grinding jar 7 itself is driven by the drive gear column 4 to rotate, and the longitudinal movement of the grinding jar 7 is achieved by utilizing the speed difference between the grinding jar 7 and the rotary table 6, forming a third type of motion for the grinding jar 7. When the grinding jar 7 moves towards the housing 1, it achieves quick installation and fixation of the grinding jar 7. When the grinding jar 7 moves in the opposite direction to the housing 1, it achieves quick disassembly of the grinding jar 7. The grinding jar 7 performs three types of motion simultaneously, increasing the grinding efficiency.

[0025] The drive gear column 4 is simultaneously meshed with the revolution table 5, the rotary table 6, and the ball mill jar 7. The number of teeth of the ball mill jar 7 meshing with the drive gear column 4 is less than the number of teeth of the rotary table 6 meshing with the drive gear column 4. The gear ring 15 is meshed with the rotary table 6.

[0026] When the drive gear 4 rotates, it drives the revolution stage 5, the rotary table 6, and the grinding jar 7 to rotate through the meshing connection structure. When the revolution stage 5, which is tightly meshed with the drive gear 4, drives the rotary table 6 to revolve, the gear ring 15, which is meshed with the rotary table 6, forces the rotary table 6 to rotate. At the same time, since the number of teeth of the grinding jar 7 and the rotary table 6 are different, the rotation speed of the grinding jar 7 and the rotary table 6 will be different. The longitudinal movement of the grinding jar 7 is achieved by using the speed difference.

[0027] A rotating bracket 8 is fixedly installed on the outer surface of the revolution platform 5, and a sliding groove 9 is opened on the inner wall of the box 1. One end of the rotating bracket 8 is rotatably installed inside the sliding groove 9.

[0028] When the revolution stage 5 rotates, the rotating bracket 8 placed inside the slide 9 fixes the revolution stage 5, preventing the revolution stage 5 from moving longitudinally.

[0029] Several rotating platforms 6 are arranged in a ring on the upper end of the revolving platform 5, and the driving gear column 4 is set on the central axis of the ring arrangement of the rotating platforms 6 to drive the several rotating platforms 6 to rotate synchronously.

[0030] When the drive gear column 4 rotates, the drive gear column 4, which is placed between each rotary table 6, can simultaneously drive multiple rotary tables 6 to rotate.

[0031] A threaded post 10 is fixedly installed at the lower end of the ball mill jar 7. The threaded post 10 is threadedly engaged with the rotary table 6. A telescopic hole 11 is opened through the upper end of the box body 1, and several threaded posts 10 are installed inside the telescopic hole 11.

[0032] When the grinding jar 7 and the rotary table 6 rotate, the grinding jar 7 moves along the direction of thread engagement by utilizing the speed difference between the grinding jar 7 and the rotary table 6. At the same time, the threaded column 10 moves inside the telescopic hole 11, realizing the rapid installation, fixing and disassembly of the grinding jar 7.

[0033] An installation button 12, a disassembly button 13, and a grinding button 14 are fixedly provided on the outer surface of the housing 1. The installation button 12, the disassembly button 13, and the grinding button 14 are electrically connected to the rotary motor 2. The installation button 12, the disassembly button 13, and the grinding button 14 are linearly distributed. Since the control method of the installation button 12, the disassembly button 13, and the grinding button 14 being electrically connected to the rotary motor 2 is existing technology, it is not described in detail in this embodiment.

[0034] When the installation button 12 is pressed, the rotary motor 2 is controlled to rotate in the forward direction. At this time, after a simple manual rotation, the grinding jar 7, which is screwed into the surface of the rotary table 6, moves towards the rotary table 6 while rotating, realizing the quick installation and fixation of the grinding jar 7. When the disassembly button 13 is pressed, the rotary motor 2 is controlled to rotate in the reverse direction. At this time, the grinding jar 7, which is screwed into the depth of the rotary table 6, moves away from the rotary table 6 while rotating, realizing the disassembly of the grinding jar 7. When the grinding button 14 is pressed, the rotary motor 2 is controlled to rotate in both forward and reverse directions in a cyclical manner, and the switching time between forward and reverse rotation is controlled to realize the cyclical movement of the grinding jar 7 inside the rotary table 6, preventing the grinding jar 7 from detaching or from being too deep and causing the parts to break.

[0035] The rotation setting of the rotary table 6 and the control of the rotary motor 2 by pressing the installation button 12, disassembly button 13 and grinding button 14 are all common technologies. The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0036] The working principle of the above embodiment is as follows: The rotary motor 2 drives the rotary shaft 3 and the upper drive gear column 4 to rotate, which drives the revolution stage 5 to revolve around the central axis. The rotation stage 6 at the upper end of the revolution stage 5 revolves accordingly. At the same time, the outer side of the rotation stage 6 meshes with the gear ring 15 and is forced to rotate, forming a planetary gear system motion. The grinding jar 7 is screwed into the rotation stage 6 through the lower threaded column 10. The grinding jar 7 and the rotation stage 6 have different numbers of teeth, resulting in a difference in their rotation speed. According to the principle of screw transmission, the grinding jar 7 is axially moved. When the rotary motor 2 rotates forward, the grinding jar 7 moves downward along the thread to achieve quick installation and fixation. When the rotary motor 2 rotates in reverse, the grinding jar 7 moves upward to complete quick disassembly. During grinding, the rotary motor 2 rotates in both forward and reverse cycles, controlling the grinding jar 7 to reciprocate slightly in the axial direction to avoid being too tight or loose. At the same time, its revolution, rotation and axial movement are combined to enhance the impact effect of the grinding media and improve the grinding efficiency. The rotating bracket 8 and the slide groove 9 cooperate to limit the axial displacement of the revolution stage 5.
