[0020] Implementation examples, by Figure 1-6 The present invention includes a base 1, a vertical plate 2 fixedly connected to the top of the base 1, a reduction motor 5 fixedly connected to one side of the vertical plate 2, a U-shaped frame 3 fixedly connected to the output shaft of the reduction motor 5, the U-shaped frame 3 being located on the other side of the vertical plate 2, the U-shaped frame 3 being composed of a telescopic plate 31, an upper mounting plate 32, and a lower mounting plate 33, an outer sphere 6 movably connected to the inner side of the U-shaped frame 3, the outer sphere 6 being composed of an upper hemisphere 61 and a lower hemisphere 62 fixedly connected by a flange, an inner sphere 7 being connected inside the outer sphere 6, and raised particles 8 being machined on the inner wall of the outer sphere 6 and the outer wall of the inner sphere 7, a first connecting rod 11 fixedly connected to the bottom of the inner sphere 7, the first connecting rod 11 passing through the lower hemisphere 62 and movably connected to the top of the lower mounting plate 33 by a bearing, a hollow tube 12 fixedly connected to the bottom of the lower hemisphere 62, and a bidirectional drive mechanism being installed inside the hollow tube 12.

[0021] When it is necessary to add materials and water, or to remove the ground materials, the flange between the upper hemisphere 61 and the lower hemisphere 62 can be separated. Since there is a telescopic plate 31 in the U-shaped frame 3, the upper mounting plate 32 can move the upper hemisphere 61 upward. At this time, materials can be added. After grinding is completed, the U-shaped frame 3 is turned horizontally and the flange is opened to separate the upper hemisphere 61 and the lower hemisphere 62, so that the ground material can be poured out.

[0022] The bidirectional drive mechanism includes a motor 15, a driving gear 16, a driven gear 17, and a ring rack 18. The motor 15, driving gear 16, and driven gear 17 are all located inside the hollow tube 12. The motor 15 is fixedly connected to the bottom of the lower mounting plate 33. The output shaft of the motor 15 passes through the lower mounting plate 33, and the driving gear 16 is fixedly connected to the output shaft of the motor 15. The driven gear 17 is fixedly connected to the outer end of the first connecting rod 11. The ring rack 18 is fixedly connected to the inner wall of the hollow tube 12. The driving gear 16 is located on one side of the driven gear 17, and it meshes with both the driven gear 17 and the ring rack 18. When the motor 15 drives the driving gear 16 to rotate, the driven gear 17 and the ring rack 18 meshing with the driving gear 16 cause the first connecting rod 11 and the hollow tube 12 to rotate in opposite directions. This, in turn, causes the outer sphere 6 and the inner sphere 7 to rotate in opposite directions, thus enabling better grinding of the material.

[0023] An annular flange 13 is fixedly connected to the bottom of the outer surface of the hollow tube 12. Two arc-shaped sliding sleeves 14, distributed to the left and right, are fixedly connected to the top of the lower mounting plate 33. The two arc-shaped sliding sleeves 14 are respectively sleeved on both sides of the annular flange 13. The hollow tube 12 is movably connected to the lower mounting plate 33 through the annular flange 13 and the arc-shaped sliding sleeves 14. The movable connection between the hollow tube 12 and the lower mounting plate 33 through the annular flange 13 and the arc-shaped sliding sleeves 14 also creates a limiting relationship between the outer sphere 6 and the lower mounting plate 33. That is, the outer sphere 6 can only rotate and will not move away from the lower mounting plate 33 unless the upper hemisphere 61 needs to be separated and lifted when adding or removing material. In this case, the upper hemisphere 61 moves away from the lower mounting plate 33 independently, which improves the stability of the outer sphere 6 during grinding rotation.

[0024] The upper mounting plate 32 is located above the lower mounting plate 33. The telescopic plate 31 is fixedly connected between the upper mounting plate 32 and the lower mounting plate 33. The top of the upper hemisphere 61 is fixedly connected to the second connecting rod 19. The top of the second connecting rod 19 is movably connected to the bottom of the upper mounting plate 32 through a bearing. The upper mounting plate 32 and the upper sphere 61 are movably connected through the second connecting rod 19. This will not affect the rotation of the upper hemisphere 61, and will also allow the upper hemisphere 61 to move up or down with the upper mounting plate 32.

[0025] The upper hemisphere 61 is fixedly connected to the top of the inner end of the upper hemisphere 61. The inner sphere 7 has an insertion hole 10 at the top. The insertion rod 9 is located above the inner sphere 7 and extends into the insertion hole 10. When the insertion rod 9 is inserted into the insertion hole 10 in the inner sphere 7, it cooperates with the first connecting rod 11 to improve the stability of the inner sphere 7 when it rotates and prevent it from shaking inside the outer sphere 6.

[0026] A sliding plate 4 is connected between the upright plate 2 and the U-shaped frame 3. The sliding plate 4 consists of an annular slide rail 41 and an annular sliding sleeve 42. The annular sliding sleeve 42 is fitted on one side of the annular slide rail 41, and the annular slide rail 41 and the annular sliding sleeve 42 are slidably connected. The annular slide rail 41 and the annular sliding sleeve 42 are respectively fixedly connected to the sides of the telescopic plate 31 and the upright plate 2 that are close to each other. The telescopic plate 31 is fixedly connected to the output shaft of the reduction motor 5. The upright plate 2 and the U-shaped frame 3 are movably connected through the sliding plate 4. First, the U-shaped frame 3 can be stably and movably connected to the side of the upright plate 2. Second, the reduction motor 5 drives the U-shaped frame 3 to rotate. During this process, the U-shaped frame 3 has good stability. The U-shaped frame 3 can be driven by the reduction motor 5 to rotate the outer ball 6 from vertical to horizontal and then back again. This reciprocating operation can improve the material grinding efficiency and grinding effect.

[0027] Working principle:

[0028] During grinding, the upper hemisphere 61 and lower hemisphere 62 are first separated, and the material is placed into the outer sphere 6. If wet grinding is required, water can be added at the same time. Then, the upper hemisphere 61 and lower hemisphere 62 are reconnected by the flange to seal the interior. Subsequently, the outer sphere 6 and inner sphere 7 are driven to rotate in opposite directions simultaneously by a bidirectional drive mechanism. Specifically, the motor 15 drives the drive gear 16 to rotate. The drive gear 16 then meshes with the driven gear 17 and the ring rack 18 to cause the first connecting rod 11 and the hollow tube 12 to rotate in opposite directions. At the same time, the first connecting rod 11 and the hollow tube 12 will drive the inner sphere 7 to rotate in opposite directions. The outer sphere 6 rotates synchronously with the inner sphere 7, thus achieving the opposite rotation of the outer sphere 6 and the inner sphere 7. The material inside the outer sphere 6 is ground by the protruding particles 8 on the outer sphere 6 and the inner sphere 7. At the same time, the U-shaped frame 3 can be driven by the reduction motor 5 to rotate from vertical to horizontal and reciprocate. When the U-shaped frame 3 rotates vertically and horizontally, it will carry the outer sphere 6 and the inner sphere 7 to rotate synchronously, so that the material in the outer sphere 6 can fully roll and contact the inner wall of the outer sphere 6 and the outer wall of the inner sphere 7 to be ground. After grinding, the U-shaped frame 3 turns horizontally and opens the flange to separate the upper hemisphere 61 and the lower hemisphere 62, so that the ground material can be poured out.
