[0002] Lotus seeds, as a traditional Chinese medicinal material and food ingredient, play an important role in Chinese food culture and traditional Chinese medicine. They are not only delicious but also have various health care effects, and are deeply loved by people. Lotus seeds contain rich nutritional components, including protein, carbohydrates, dietary fiber, vitamins, and minerals such as calcium, phosphorus, and iron.

[0003] As a nutritious food ingredient, the processing and grinding process of lotus seeds involves multiple steps such as cleaning, soaking, grinding, filtering, concentrating, and drying. These steps work together to convert lotus seeds into lotus seed powder that is convenient for storage and consumption. Modern processing technologies not only improve production efficiency but also ensure the nutritional components and taste of lotus seed powder.

[0004] During the process of grinding lotus seeds, grinding equipment is used, mainly for processing lotus seeds into powder.

[0026] A lotus seed processing and grinding device includes a crushing box 1 and a grinding box 2 below it. The crushing box 1 first crushes the lotus seeds, and the crushed lotus seeds enter the inside of the grinding box 2 for grinding, which speeds up the grinding speed. A feed hopper 3 is arranged at the top of the crushing box 1. The feed hopper 3 penetrates through the top wall of the crushing box 1 and has a structure of one inlet and two outlets, which speeds up the feeding speed of the lotus seeds. A guide pipe 5 is communicated with the bottom of the crushing box 1. The crushing box 1 is a cylindrical structure with a conical bottom, which is convenient for the lotus seeds to enter the guide pipe 5 along the conical structure and then enter the inside of the grinding box 2 through the guide pipe 5 for grinding. The crushing box 1 is fixedly arranged on the top wall of the grinding box 2, and servo motors 12 are arranged on both the top wall of the crushing box 1 and the outer wall of the guide pipe 5.

[0027] A crushing roller 4 is rotatably arranged below the feed hopper 3. A support frame 13 is fixedly arranged at the bottom of the crushing box 1, which can support the crushing roller 4. The support frame 13 includes a central support block 14. The support block 14 is fixedly connected to the conical inner wall of the crushing box 1 through four support rods 15. The crushing roller 4 includes a crushing shaft 16 rotatably arranged between the top wall of the crushing box 1 and the top wall of the support block 14. Crushing blades 17 are arranged on the outer wall of the crushing shaft 16. The crushing shaft 16 is arranged at the output end of the servo motor 12.

[0028] Start the servo motor 12 to drive the crushing shaft 16 to rotate, and then drive the crushing blades 17 to rotate and crush the lotus seeds. The crushed lotus seeds enter the inner part of the lower guide pipe 5 from the gap between the support block 14, the support rods 15 and the conical inner wall of the crushing box 1.

[0029] A material guiding pipe 5 is internally provided with a material guiding member 6 in a rotatable manner. Two shunt pipes 7 are communicated with the bottom of the material guiding pipe 5. The material guiding member 6 includes a rotating shaft 18 rotatably arranged between the material guiding pipes 5. The rotating shaft 18 is arranged at the output end of a servo motor 12. A triangular material guiding block 19 is fixedly arranged on the outer wall of the rotating shaft 18. The triangular material guiding block 19 deflects left and right, and can alternately guide the material into the two shunt pipes 7. The bottoms of the two shunt pipes 7 are respectively arranged above the grinding areas between the fixed grinding column 8 and the two adjusting grinding columns 9.

[0030] The servo motor 12 is set to rotate left and right intermittently by a certain angle, so as to drive the rotating shaft 18 to rotate, and then drive the triangular material guiding block 19 to rotate left and right, so that the top of the triangular material guiding block 19 contacts the inner wall of the material guiding pipe 5. The flowing-down lotus seeds can be intermittently conveyed into the two shunt pipes 7 respectively, and then flow from the shunt pipes 7 to the lower grinding areas for grinding.

[0031] The grinding box 2 includes a fixed grinding column 8 in the middle. Two adjusting grinding columns 9 are respectively movably arranged on both sides of the fixed grinding column 8. By adjusting the two adjusting grinding columns 9 to close or separate from each other, the grinding distance between them and the fixed grinding column 8 is adjusted. Both the fixed grinding column 8 and the adjusting grinding column 9 include a central shaft 20. A grinding ring 21 is fixedly arranged on the outer wall of the central shaft 20. A number of protrusions 22 are distributed on the outer wall of the grinding ring 21. The central shaft 20 in the adjusting grinding column 9 rotates to drive the grinding ring 21 to rotate, so that the protrusions 22 in the fixed grinding column 8 and the adjusting grinding column 9 can contact and rotate against each other for grinding. The central shaft 20 in the fixed grinding column 8 is fixedly arranged on the inner wall of the grinding box 2. Both of the two adjusting grinding columns 9 are slidably arranged on the outer circumference of a group of bidirectional lead screws 10. A collection box 11 is communicated with the bottom of the grinding box 2.

[0032] One end of a group of bidirectional lead screws 10 is rotatably arranged on the inner wall of the grinding box 2, and the other end sequentially passes through the central shaft 20 in the fixed grinding column 8 and the corresponding side wall of the grinding box 2 and is fixedly provided with a synchronous gear 23. Through holes are arranged at both ends of the central shaft 20 in the fixed grinding column 8. The other end of the group of bidirectional lead screws 10 can rotate inside the through holes. The two synchronous gears 23 are movably connected by a gear belt 24, and one of the synchronous gears 23 is arranged at the output end of another servo motor 12. When the servo motor 12 is started, under the synchronous action of the gear belt 24, it drives the synchronous gear 23 to rotate, and then drives a group of bidirectional lead screws 10 to rotate.

[0033] A moving seat 25 is slidably arranged at both the forward and reverse threads of a group of bidirectional lead screws 10. A cavity 26 is arranged inside the moving seat 25 at one end, and a servo motor 12 is also arranged inside the cavity 26. One end of the central shaft 20 in the adjusting grinding column 9 is arranged at the output end of the servo motor 12, and the other end is rotatably arranged on the inner wall of the corresponding moving seat 25. The two adjusting grinding columns 9 can be closed or separated from each other.

[0034] The rotation of the group of bidirectional lead screws 10 can drive the moving seats 25 to close or separate from each other on the bidirectional lead screws 10, so that the two adjusting grinding columns 9 can close or separate from each other, and the grinding distance between them and the fixed grinding column 8 can be adjusted, thereby adjusting the grinding fineness of the lotus seeds.

[0035] Start the servo motor 12 in the cavity 26 to drive the central shaft 20 to rotate, and then drive the grinding rings 21 in the two adjusting grinding columns 9 to rotate, making a rotational movement relative to the grinding rings 21 in the fixed grinding column 8 to achieve grinding.

[0036] The collection box 11 is movably placed under the grinding box 2. A material guiding plate 28 is arranged on the bottom wall of the grinding box 2. A discharge flexible pipe 27 is fixedly arranged at the bottom end of the material guiding plate 28. A through hole adapted to the discharge flexible pipe 27 is arranged at the top of the grinding box 2. The discharge flexible pipe 27 passes through the bottom wall of the collection box 11 and extends into the collection box 11 through the through hole. The ground lotus seed powder falls onto the lower material guiding plate 28 and then falls into the discharge flexible pipe 27 along the material guiding plate 28, and is finally collected inside the collection box 11, which is convenient for subsequent packaging.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
