[0001] The utility model relates to the technical field of crushing, in particular to an ultra-fine crusher for bentonite. Background Art

[0002] Bentonite is also called montmorillonite, saponite or bentonite rock. Bentonite is a non-metallic mineral mainly composed of montmorillonite. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons.

[0003] In construction, it is necessary to ultra-finely crush bentonite on site. However, during the crushing process of the existing crushers, only single crushing of bentonite is carried out, which often fails to reach the required fineness on site. Moreover, it will even cause the unnecessary diffusion of bentonite in the equipment, and it is also difficult to ensure the fineness of bentonite, unable to meet the construction standards required for on-site construction, resulting in the impact on the construction period during the construction process. Summary of the Invention

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1 - 3 , a superfine pulverizer for bentonite, including a machine body 1 with a feed chute opening 2 provided at the top. A first guiding sliding plate 9 corresponding to the feed chute opening 2 is fixedly connected inside the machine body 1. A rotating motor 3 and a driving motor 15 are respectively fixedly arranged on the machine body 1. A crushing mechanism driven by the rotating motor 3 and used for initially crushing bentonite is installed inside the machine body 1.

[0021] The crushing mechanism includes a driving turntable 4 and a driven turntable 8 symmetrically and rotatably installed inside the machine body 1. The driving turntable 4 is fixedly connected to the output end of the rotating motor 3. When the rotating motor 3 rotates, it will drive the driving turntable 4 to rotate. A linkage connecting rod 5 is arranged between the driving turntable 4 and the driven turntable 8. The purpose of the linkage connecting rod 5 is to drive the driven turntable 8 to rotate synchronously;

[0022] Driving connecting rods 6 are correspondingly and rotatably sleeved on both sides of the linkage connecting rod 5. When the linkage connecting rod 5 rotates with the driving turntable 4, it will drive the driving connecting rods 6 to perform reciprocating motions in the up and down directions. A rolling plate 7 is arranged inside the machine body 1. A flange for rolling bentonite is provided at the bottom of the rolling plate 7. The rolling plate 7 is rotatably connected to the driving connecting rods 6. Therefore, when the driving connecting rods 6 perform up and down motions, the rolling plate 7 also performs reciprocating motions in the up and down directions. A bearing plate 11 corresponding to the rolling plate 7 is fixedly installed inside the machine body 1. When the rolling plate 7 moves downward, it just forms extrusion and crushing of bentonite with the bearing plate 11;

[0023] A limiting horizontal plate 24 is fixedly installed inside the machine body 1. When the rolling plate 7 moves downward to reach the limiting horizontal plate 24, it will be supported by the limiting horizontal plate 24 and stop rolling. And a vertical limiting rod 10 is fixedly installed on the limiting horizontal plate 24. The rolling plate 7 is slidably sleeved on the vertical limiting rod 10. When the rolling plate 7 moves back and forth, it is affected by the vertical limiting rods 10 on both sides, which can keep the movement process balanced and more stable. The crushing mechanism includes a push-pull member arranged in a matching manner with the crushing mechanism.

[0024] The push-pull member includes a hydraulic telescopic machine 12 fixedly connected to the machine body 1. A push plate 13 is fixedly installed at the output end of the hydraulic telescopic machine 12. After the crushing mechanism completes the crushing work, the hydraulic telescopic machine 12 will drive the push plate 13 to push out the crushed bentonite. A second guiding sliding plate 14 is fixedly installed inside the machine body 1. The pushed-out bentonite will enter the pulverizing mechanism after passing through the second guiding sliding plate 14.

[0025] A pulverizing mechanism driven by a driving motor 15 and used for further pulverizing bentonite is installed inside the machine body 1. The pulverizing mechanism includes a driving wheel 16 rotatably installed outside the machine body 1, and the driving wheel 16 is fixedly connected to the output end of the driving motor 15. When the driving motor 15 is started, the output end of the driving motor 15 will drive the driving wheel 16 to rotate;

[0026] A driven wheel 18 is rotatably connected outside the machine body 1. A belt 17 is sleeved between the driving wheel 16 and the driven wheel 18. When the driving wheel 16 rotates, it will drive the driven wheel 18 to rotate through the action of the belt 17. A first rolling roller 20 is rotatably installed inside the machine body 1, and the first rolling roller 20 is fixedly connected to the driving wheel 16. The rotation of the driving wheel 16 will drive the first rolling roller 20 to rotate. A driving gear 19 fixedly connected to the driven wheel 18 is rotatably installed outside the machine body 1. Therefore, the driven wheel 18 will also drive the driving gear 19 to rotate;

[0027] A driven gear 21 meshing with the driving gear 19 is rotatably installed outside the machine body 1. Due to the meshing effect, the driving gear 19 will drive the driven gear 21 to rotate. A second rolling roller 22 is rotatably installed inside the machine body 1, and the second rolling roller 22 is fixedly connected to the driven gear 21. Therefore, the driven gear 21 will drive the second rolling roller 22 to rotate.

[0028] A third guiding sliding plate 23 is arranged below the pulverizing mechanism. The crushed bentonite will slide out of the machine body 1 through the third guiding sliding plate 23.

[0029] It should be noted that the specific model specifications of the motor and cylinder need to be selected according to the actual specifications of the device, etc. The specific selection calculation method uses the existing technology in this field, so it will not be elaborated here.

[0030] The functional principle of the present utility model can be described through the following operation modes:

[0031] Pour bentonite into the feeding chute 2, and the bentonite will fall onto the bearing plate 11 through the first guiding sliding plate 9;

[0032] Start the rotating motor 3. The output end of the rotating motor 3 drives the driving turntable 4 to rotate. The driving turntable 4 drives the linkage rod 5 and the driven turntable 8 to rotate. While the linkage rod 5 rotates, it will drive the driving rod 6 to perform reciprocating up and down movements. The driving rod 6 will drive the rolling plate 7 to perform reciprocating up and down movements, thereby realizing the rolling and crushing of the bentonite on the bearing plate 11.

[0033] When the bentonite undergoes the first round of crushing, start the hydraulic telescopic machine 12. Use the push plate 13 connected to the end of the hydraulic telescopic machine 12 to push out the bentonite to be crushed staying on the surface of the bearing plate 11. The pushed-out bentonite will fall into the crushing mechanism through the second guiding sliding plate 14.

[0034] Start the driving motor 15. The output end of the driving motor 15 will drive the driving wheel 16 to rotate. The driving wheel 16 will drive the driven wheel 18 to rotate. The rotation of the driven wheel 18 drives the first rolling roller 20 to rotate. The driven wheel 18 will also drive the driving gear 19 to rotate. The rotation of the driving gear 19 will drive the rotation of the driven gear 21. The rotation of the driven gear 21 will drive the second rolling roller 22 to rotate, thereby realizing the secondary crushing of the bentonite. The crushed bentonite will finally be discharged through the third guiding sliding plate 23.
