[0002] Bentonite is a natural mineral mainly composed of layered silicates. The formation of bentonite is usually related to rock weathering and sedimentation. It is characterized by high ion exchange capacity and adsorption performance, and can expand under the action of water or other adsorbents and maintain the stability of its interlayer structure. Bentonite is usually obtained through mining and refining processes. The main production steps include excavation, crushing, grinding and refining. Among them, the crushing production step needs to be completed by a bentonite crusher.

[0003] However, the existing bentonite crushers have the following disadvantages. Since most bentonite crushers are provided with a screening mesh to screen the crushed bentonite raw materials into the required particle sizes, but during screening, some bentonite raw material particles are not completely screened due to different screening states, which will reduce the screening efficiency of the crusher. Therefore, the current bentonite crushers need to be improved. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 3 and Figure 5, the present utility model provides a technical solution: a bentonite crusher with a screening structure, including a machine body 1 and a discharge port 5. An inlet hopper 2 is installed above the machine body 1. A crushing assembly 3 is installed inside the machine body 1 near the lower part of the inlet hopper 2. The discharge port 5 is connected to the lower part of the machine body 1. A blanking port 7 is installed inside the machine body 1 near the lower part of the crushing assembly 3. A screening chamber 9 is provided inside the machine body 1 near the lower part of the blanking port 7. A first sieve mesh 14 and a second sieve mesh 13 are installed inside the screening chamber 9. A diversion plate 4 is installed inside the inlet hopper 2. The cross-sectional shape of the diversion plate 4 is "L" shaped, and a number of through holes are opened on the inner side of the diversion plate 4.

[0027] Please refer to Figures 1 - 4 and Figure 7 , guide mechanisms 6 are installed on both sides of the machine body 1. A chute 11 is provided inside the guide mechanism 6. The guide mechanism 6 includes a first motor 601, a lead screw 602, a circulation box 603, a slider 604, a material receiving plate 605 and a baffle 606. Circulation boxes 603 are connected to both sides of the machine body 1. The lead screw 602 is installed in the built-in groove of the circulation box 603 through a bearing. A first motor 601 connected to the lead screw 602 through a coupling is installed on the outside of the circulation box 603. The slider 604 is threadedly sleeved on the outside of the lead screw 602. A material receiving plate 605 is connected to one side of the slider 604. A baffle 606 is connected to the lower part of the material receiving plate 605. Both ends of the slider 604 are slidably connected to the chute 11. Feeding ports 15 are opened on both sides of the machine body 1 near the circulation boxes 603. The structure of the material receiving plate 605 is inclined, and a diversion plate is installed on the inner wall of the machine body 1 near the feeding ports 15.

[0028] In specific implementation, since most bentonite crushers are equipped with a screening mesh to screen the crushed bentonite raw materials and screen the bentonite raw materials into the required particle sizes, however, during screening, some bentonite raw material particles are not completely screened due to different screening states, reducing the screening efficiency of the crusher. After the bentonite raw materials are crushed by the crushing assembly 3, they then fall from the feeding port 7 into the screening chamber 9 and are screened by the first sieve 14 and the second sieve 13. Then, some of the unscreened bentonite raw materials roll to the openings on both sides of the machine body 1 and fall on the material receiving plate 605. Then, the first motor 601 is started to drive the screw rod 602 to rotate. Subsequently, a threaded engagement occurs between the slider 604 and the screw rod 602, and the slider 604 drives the material receiving plate 605 to move upward on the screw rod 602, causing the material receiving plate 605 to push the bentonite raw materials to the material guiding port 15. At the same time, the material receiving plate 605 drives the baffle 606 to rise and block the opening of the machine body 1. Then, the bentonite raw materials fall onto the first sieve 14 again from the material guiding port 15 and are screened in a cycle again, which can screen the incompletely screened bentonite raw materials again and improve the screening efficiency of the bentonite crusher.

[0029] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown in, a bracket 10 is fixedly installed inside the machine body 1 close to the screening chamber 9. A transmission mechanism 8 is connected below the bracket 10. A second motor 16 is connected to one side of the transmission mechanism 8. A scraping plate 12 is connected below the transmission mechanism 8 close to the discharge port 5. The transmission mechanism 8 includes a first gear 801, a second gear 802, a drive shaft 803, a rotating cylinder 804, and a transmission shaft 805. The transmission shaft 805 is connected below the bracket 10 through a bearing. One end of the transmission shaft 805 away from the bracket 10 is connected to the rotating cylinder 804. The first gear 801 is fixedly sleeved on the outer side of the transmission shaft 805. The second gear 802 is engaged with one side of the first gear 801. The lower part of the rotating cylinder 804 is connected to the scraping plate 12. One side of the second gear 802 is connected to the drive shaft 803. One end of the drive shaft 803 is connected to the second motor 16 through a coupling, and the second motor 16 is located outside the machine body 1.

[0030] In specific implementation, since the bentonite raw material is in a granular and powdery state after being crushed and screened, when the bentonite raw material is somewhat moist, it may adhere to the inner wall of the machine body 1 near the discharge port 5. The second motor 16 can be started to drive the transmission shaft 805 to rotate. The transmission shaft 805 drives the second gear 802 to rotate, and the second gear 802 then drives the first gear 801 to rotate. The first gear 801 causes the drive shaft 803 to drive the rotating cylinder 804 to rotate, and the rotating cylinder 804 then drives the scraping plate 12 to rotate. The scraping plate 12 scrapes on the bottom inner wall of the machine body 1 to prevent the bentonite raw material from adhering to the inner wall, thereby improving the feeding efficiency of the bentonite crusher.

[0031] Working principle: When using the bentonite crusher with a screening structure, first, the bentonite raw material is put in from the feed hopper 2 and dispersed by the diversion plate 4, which facilitates uniform crushing by the crushing assembly 3. Then, the crushed raw material is discharged from the discharge port 7 into the screening chamber 9. The raw material is screened by the first screen 14 and the second screen 13, and at the same time, the raw material is circularly screened by the guiding mechanism 6. After the raw material is evenly screened, it falls into the inner cavity of the machine body 1 near the discharge port 5. At the same time, the scraping plate 12 is driven by the transmission mechanism 8 to scrape on the inner wall of the inner cavity to prevent the raw material from adhering to the inner wall. Finally, the raw material is discharged through the discharge port 5, improving the screening efficiency and feeding efficiency of the bentonite crusher. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
