[0032] As Figures 1 to 7 shown, according to an embodiment of the present utility model, there is provided a grinding device capable of precisely adjusting gears, including a bin body 1, which has an accommodation space for accommodating substances to be ground inside; a grinding head fixing frame 2 is fixedly installed inside the bin body 1, and a fixed grinding head 7 is fixedly connected to the bottom of the grinding head fixing frame 2. The bin body 1 also includes a bin body bottom cover 14. The bin body bottom cover 14, the fixed grinding head 7, and the grinding head fixing frame 2 are fixedly connected by screws 15, ensuring the stability of the grinding device during operation, reducing vibration and displacement, extending the service life of the equipment, and facilitating maintenance and cleaning; at the same time, the structural design of the bin body 1 and the bin body bottom cover 14 is also conducive to cleaning residual materials and maintaining good sanitary conditions.

[0033] The central shaft 3 passes through the grinding head fixing frame 2 and can rotate relative to the grinding head fixing frame 2; this makes it relatively simple to disassemble and replace the fixed grinding head 7, which is conducive to daily maintenance and quick replacement of different types of grinding heads to meet different grinding requirements. The driving grinding head 10 is connected to the central shaft 3. The driving grinding head 10 is arranged inside the fixed grinding head 7 and can have a gap relative to the driving grinding head 10. The grinding substance is ground in the gap, and the gap forms a grinding area. By adjusting the size of the gap between the driving grinding head 10 and the fixed grinding head 7, precise control of the grinding fineness can be achieved. This design allows the user to adjust the grinding degree according to needs, is suitable for different materials and grinding precision requirements, and improves the flexibility and adaptability of the grinding process.

[0034] The central shaft 3 is connected with a height adjustment device. The height adjustment device includes an adjustment bracket 16 which is connected to the central shaft 3. The adjustment bracket 16 is provided with a plurality of gears 161. Inside the bottom shell 17, there is a gear shifting clamping part 171. The bottom shell 17 can rotate relative to the adjustment bracket 16, so that the gear shifting clamping part 171 changes to different positions of the gear 161. The adjustment bracket 16 is fixed to the driving grinding head 10, thereby adjusting the vertical position relationship between the driving grinding head 10 and the fixed grinding head 7, and further adjusting the fineness of the grinding material during the operation of the grinder. After the driving grinding head 10 and the fixed grinding head of the grinder are adjusted, the effective flow and distribution are improved, which helps to improve the grinding efficiency, ensure the uniformity of the grinding product, and reduce the phenomena of over-grinding and under-grinding.

[0035] Through the height adjustment device on the central shaft 3, through the cooperation of the multiple gears 161 on the adjustment bracket 16 and the gear shifting clamping part 171 inside the bottom shell 17, the precise adjustment of the distance between the driving grinding head 10 and the fixed grinding head 7 is realized. According to the grinding requirements, by simply operating to change the position of the adjustment bracket 16 and finely adjusting the vertical position relationship, the purpose of controlling the grinding fineness is achieved, and the grinding precision and application range are improved.

[0036] The design with multiple gears increases the flexibility of the grinder. Users can quickly select the appropriate gear according to different material characteristics and expected grinding effects, and can complete the adjustment without complex tools or professional knowledge, improving the user experience and the operation convenience of the equipment. By adjusting the height of the driving grinding head 10, not only can the grinding fineness be changed, but also the grinding requirements of more types of materials can be adapted. Whether it is hard or soft materials, or raw materials that need to be crushed to different degrees, the best grinding configuration can be found through adjustment, enhancing the versatility and market adaptability of the equipment.

[0037] Precise gap adjustment helps to maintain an ideal material flow rate and grinding pressure, avoiding low grinding efficiency caused by too large a gap or material blockage and over-grinding caused by too small a gap. Thus, while ensuring the grinding efficiency, the quality and consistency of the grinding product are improved. The design of the height adjustment device simplifies the equipment maintenance and adjustment process, reduces the operation difficulty, enables non-professional personnel to easily complete the adjustment of grinding parameters, reduces the risk of equipment damage caused by improper operation, and extends the service life of the equipment.

[0038] The height adjustment device includes a spring cap 4. A spring cap 4 is sleeved between the central shaft 3 and the grinding head fixing frame 2.

[0039] The height adjustment device further includes a spring 5, which is sleeved on the central shaft 3. The driving grinding head 10 is fixedly sleeved with a grinding head bracket 9. The first end of the spring 5 is connected to the spring cap 4, and the second end of the spring 5 is connected to the grinding head bracket 9, and the spring 5 forms a thrust force. Through the combination of the spring cap 4 and the spring 5, the dynamic adjustment of the distance between the driving grinding head 10 and the fixed grinding head 7 is realized. When the distance between the driving grinding head 10 and the fixed grinding head 7 is adjusted to be larger, the spring provides a thrust force to push the driving grinding head 10 away.

[0040] Below the grinding head fixing frame 2, there is an inner housing 12, which is connected to the bottom housing 17. Inside the inner housing 12, there are positioning beads 11. At the bottom edge of the grinding head fixing frame 2, there are a plurality of positioning grooves 21. While the shifting card 171 changes to different positions of the gear position 161, the positioning beads 11 assist the shifting card 171 in positioning and adjusting.

[0041] The structural design of the inner housing 12 and the bottom housing 17, especially the cooperation between the positioning beads 11 and the positioning grooves 21, ensures accurate positioning when adjusting the height, enhancing the stability of the entire device. This design helps to quickly and accurately lock the required position when adjusting the grinding fineness, avoiding unnecessary loosening or misalignment. And the ticking and jerky feeling of the positioning bead changing positions enhances the user experience.

[0042] Inside the grinding device, there is also a light guide rod 8, and an outer light guide tube 6 is sleeved on the outer wall of the light guide rod 8; when the shifting card 171 changes to different positions of the gear position 161, the light guide rod 8 can change different color lights. The bottom housing 17 is a transparent bottom housing, and the light of the light guide rod 8 can penetrate the bottom housing 17.

[0043] The optical path design of the light guide rod 8 and the light guide tube 6 makes the shifting operation intuitive and visible. As the position of the shifting card 171 changes, the light guide rod 8 indicates the current gear position by changing the color light, which is not only beautiful but also improves the convenience and accuracy of the operation. The user can intuitively understand the working state and settings of the grinder, enhancing the user experience. Using the transparent bottom housing 17, combined with the light penetration effect of the light guide rod 8, not only beautifies the appearance of the device but also facilitates observing the internal working conditions, facilitating inspection and maintenance. At the same time, it also provides visual feedback to the operator, enhancing the technological sense and interactivity of the device.

[0044] The gear position 161 provides eight stepped gear positions, offering more diverse grinding fineness settings, improving the flexibility and adaptability of the grinding process, and meeting the detailed requirements in different application scenarios.

[0045] An outer housing 13 is also sleeved outside the inner housing 12. Rotating the outer housing 13 can drive the inner housing 12 and the transparent bottom housing 17 to rotate together. The sleeving of the inner housing 12 and the outer housing 13 strengthens the stability and durability of the overall structure and also facilitates possible maintenance and upgrades.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
