[0002] Wheat is a general term for plants of the genus Triticeae. The representative species is common wheat, which is a grass plant and a cereal crop widely grown around the world. The caryopsis of wheat is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. A wheat mill is needed to grind wheat into powder.

[0003] The application number in the existing public technology is: CN202321674206.3 A combined grinding mechanism of a wheat flour mill, including a body, a feeding assembly is installed on the top of the body, a grinding assembly is installed inside the body, a collecting assembly is installed inside the body, the feeding assembly includes a feed hopper fixedly connected to the top of the body, a screen is fixedly connected to the inside of the feed hopper, a vibration motor is fixedly connected to the back of the feed hopper, a feed hole is opened on the top of the body, the grinding assembly includes a No. 1 motor fixedly connected to the left side of the body, the inner right side wall of the body is rotatably connected to two rotating shafts through bearings, the left side of the rotating shaft is fixedly connected to a gear, the outer side of the rotating shaft is fixedly connected to a crushing roller, and the inner top wall of the body is fixedly connected to a limiting plate.

[0004] However, the above patent still has certain disadvantages when used: although it can realize multiple grinding operations of wheat through the crushing roller and the grinding disc, the distance between the structures used for grinding cannot be adjusted, which leads to the fact that the particle size of wheat flour that can be processed by the device is relatively single, which cannot well meet the different needs of different people, limits the scope of application of the device, and greatly reduces the overall practicality. Moreover, it can only process one type of wheat flour at a time, and the overall use effect is not very ideal.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
