The output end of the drive motor 4 is fixedly connected to a first drive shaft 5, one end of which extends into the interior of the grinding box 3. The first drive shaft 5 and the grinding box 3 are movably connected by a rolling bearing.

[0036] In this implementation scheme, the user places the corn raw material inside the filter frame 8 and starts the drive motor 4 to work, so that the crushing mechanism crushes the raw material and the crushing mechanism further crushes the crushed raw material.

[0037] To achieve the purpose of crushing, this device adopts the following technical solution: The crushing mechanism also includes a second drive shaft 6, which is embedded inside the other side of the crushing box 1. The second drive shaft 6 is movably connected to the grinding box 3 via a rolling bearing. A connecting shaft 7 is fixedly connected between the first drive shaft 5 and the second drive shaft 6. A filter frame 8 is provided inside the crushing box 1.

A driven gear 12 is provided on the top of the drive gear 11, which is meshed with the driven gear 12. A movable shaft 13 is provided inside the crushing box 1, which is fixedly embedded inside the driven gear 12. One end of the movable shaft 13 extends to the outside of one side of the crushing box 1. A first sprocket 14 and a second sprocket 15 are provided on one side of the crushing box 1. The first sprocket 14 is fixedly sleeved on the outside of the first drive shaft 5, and the second sprocket 15 is fixedly sleeved on the outside of the movable shaft 13.

[0038] When the user starts the drive motor 4, the drive motor 4 drives the first drive shaft 5 and the connecting shaft 7 to rotate. The rotation of the connecting shaft 7 drives multiple crushing blades to rotate, crushing the corn raw material. At the same time, the first drive shaft 5 and the first sprocket 14 rotate. The rotation of the first sprocket 14 drives the second sprocket 15 and the movable shaft 13 to rotate. The rotation of the movable shaft 13 drives the drive gear 11 and the driven gear 12 to rotate, thereby driving the connecting pipe 9 and the filter frame 8 to rotate. The rotation of the filter frame 8 is opposite to the rotation of the crushing blades, so the raw material will be repeatedly crushed. The design of the filter frame 8 ensures that only the completely crushed raw material will fall into the grinding box 3.

[0039] To achieve the grinding purpose, the device adopts the following technical solution: The grinding mechanism includes a third sprocket 17, which is located on the other side of the crushing box 1. The third sprocket 17 is fixedly sleeved on the outside of the second transmission shaft 6. A fourth sprocket 18 is provided on one side of the grinding box 3.

[0040] The rotation of connecting shaft 7 and second transmission shaft 6 drives the third sprocket 17 and the fourth sprocket 18 to rotate. The rotation of the fourth sprocket 18 drives one of the transmission rods 20 to rotate. The rotation of one of the transmission rods 20 drives multiple gears 21 to rotate. The rotation of multiple gears 21 drives multiple crushing rollers 19 to rotate, so that the multiple crushing rollers 19 crush the raw material. The design of scraper 22 prevents the corn raw material from sticking to the outside of the crushing rollers 19.

[0041] The usage process of this utility model is as follows: The user places the corn raw material inside the filter frame 8, starts the drive motor 4, causing the crushing mechanism to crush the raw material, and the crushing mechanism to further crush the crushed raw material. The user starts the drive motor 4, which drives the first drive shaft 5 and the connecting shaft 7 to rotate. The rotation of the connecting shaft 7 drives multiple crushing blades to rotate, crushing the corn raw material. At the same time, the first drive shaft 5 and the first sprocket 14 rotate. The rotation of the first sprocket 14 drives the second sprocket 15 and the movable shaft 13 to rotate. The rotation of the movable shaft 13 drives the drive gear 11 and the driven gear 12 to rotate. This causes the connecting pipe 9 and the filter frame 8 to rotate. The rotation of the filter frame 8 is opposite to the rotation of the crushing blades, so the raw material will be repeatedly crushed. The design of the filter frame 8 ensures that only the completely crushed raw material will fall into the grinding box 3. The rotation of the connecting shaft 7 and the second transmission shaft 6 drives the third sprocket 17 and the fourth sprocket 18 to rotate. The rotation of the fourth sprocket 18 drives one of the transmission rods 20 to rotate. The rotation of one of the transmission rods 20 drives multiple gears 21 to rotate. The rotation of multiple gears 21 drives multiple crushing rollers 19 to rotate, so that the multiple crushing rollers 19 crush the raw material. The design of the scraper 22 prevents the corn raw material from sticking to the outside of the crushing rollers 19.
