Description

Technical Field

[0001] The utility model relates to the technical field of grain processing and grinding, in particular to a grain grinding device used for grain processing. Background Art

[0002] Coarse grains usually refer to sorghum, millet, buckwheat (sweet buckwheat, bitter buckwheat), oats (naive), barley, foxtail millet, sorghum, coix seed, amaranth, as well as kidney beans (kidney beans), mung beans, adzuki beans (red beans, red beans), broad beans, peas, cowpeas, lentils (lentils), black beans, etc. Coarse grains are becoming more and more popular as a healthy food. The grinding device needed for producing food with coarse grains is used to grind the coarse grains.

[0003] Publication number "CN211134077U" provides a grain mill for grain production, which utilizes a crushing roller to crush the grains. The crushed grains are guided to a mixing drum via a guide plate, and the mixing drum is used to separate large grains. The brush on the partition can clean the leakage holes on the mixing drum when the mixing drum rotates to avoid blockage of the leakage holes.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the grain mill can grind the grains with the crushing roller, the mill can only grind the grains once in actual use, resulting in the grains not being ground finely enough, thus affecting the quality of the grains for later sale. In addition, the crushing roller structure in the mill is prone to getting stuck in actual use, and the staff is required to stop the mill to clean the crushing roller, which results in low grinding efficiency. The practicality of the mill needs to be improved. Utility Model Content

[0032] Embodiment 2:

[0033] On the basis of the first embodiment, in this embodiment, the fine grinding movable plate 52 is driven to rotate together by the transmission vertical rod 44, so that the continuously rotating fine grinding movable plate 52 further grinds the grains in the fine grinding chamber 53 under the friction force of the fine grinding lower tooth pattern 521 and the fine grinding upper tooth pattern.

[0034] The fine grinding assembly 5 includes a fine grinding fixed plate 51, a fine grinding movable plate 52 and a centralized guide bucket 54. The fine grinding movable plate 52 is arranged on the lower side of the annular side surface of the transmission vertical rod 44.

The through hole 522 facilitates the transmission vertical rod 44 to be inserted and fixed inside the fine grinding movable plate 52. Second fixed struts 511 are symmetrically provided on the left and right sides and the front and rear sides of the annular side surface of the fine grinding fixed plate 51, and the second fixed struts 511 will support and fix the fine grinding fixed plate 51.

[0036] Working principle: In the process of processing some grains, it is necessary to grind the grains. The staff first starts the torque motor 46, so that the torque motor 46 drives the transmission vertical rod 44 to rotate, and the transmission vertical rod 44 will drive the coarse grinding movable plate 43 to rotate together. At the same time, the transmission vertical rod 44 will also drive the fine grinding movable plate 52 to rotate together, and then pour a proper amount of grains to be ground into the introduction bucket 3, so that the grains in the introduction bucket 3 slide into the coarse grinding cavity 45 through the guide drop cavity 21 and the guide drop tube 41. At this time, the coarse grinding movable plate 43 that keeps rotating will grind the grains in the coarse grinding cavity 45 under the friction force of the coarse grinding lower tooth pattern 431 and the coarse grinding upper tooth pattern. The grains are coarsely ground, and the coarsely ground grain powder will slide outward and fall downward, and then the centralized guide bucket 54 will guide the fallen grain powder into the fine grinding chamber 53. At this time, the fine and coarse grinding disc 43 that keeps rotating will further grind the grains in the fine grinding chamber 53 under the friction force of the fine grinding lower tooth pattern 521 and the fine grinding upper tooth pattern, so that the grains are ground more finely, and the finely ground grain powder will slide outward and fall downward, and finally be guided to the storage cart 7 for temporary storage through the discharge cavity 11 and the discharge pipe 8. When all the grains in the grinding barrel 1 are ground and discharged, the torque motor 46 can be turned off.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
