Abstract
Description
Technical Field
[0001] The present application relates to the technical field of yellow millet processing, and in particular to a rice milling machine for yellow millet processing. Background Art
[0002] Yellow millet (a type of millet) generally refers to millet (Psoralea cochinchinensis, Poaceae). Millet is an annual cultivated herbaceous plant in the genus Panicum in the Poaceae family. Its leaves are linear or linear-lanceolate, gradually tapering to a nearly rounded base, often with rough margins. Its inflorescence is a panicle, spreading or densely packed, with thick or slender branches. Its seeds are oval, oblong, or round. Its flowering and fruiting period is July-October. Millet was first mentioned in the "Compendium of Materia Medica" (Compendium of Materia Medica Annotations) and was named millet. Millet is native to Shanxi, Hebei, Gansu, and Qinghai in China. It is cultivated in mountainous areas throughout Northwest, North, Southwest, Northeast, South, and East China. It occasionally grows wild in Xinjiang. It is also cultivated in warmer regions of Asia, Europe, America, and Africa. Millet prefers strong sunlight and is heat-tolerant, drought-tolerant, and tolerant of poor soil quality, but not frost or waterlogging. It has a short growth cycle and prefers warm, short-day temperatures, so it is typically sown in dryland areas. Propagation methods include row sowing, broadcast sowing, and ridge sowing. Millet is one of humanity's earliest cultivated cereals. Its grains are rich in starch and can be eaten or used to make wine, while its stalks and leaves can be used as livestock feed. According to historical texts such as the Compendium of Materia Medica and the Compendium of Materia Medica, it has diuretic, swelling-reducing, and hemostatic properties. It is also used to treat conditions such as athlete's foot and hematuria during pregnancy. The oracle bone script for "ji" (a Chinese character for millet) depicts a figure tending grain, and its earliest meaning was transplanting. Millet, the king of the five grains, was the primary agricultural sector in ancient China, and land and grain were considered the foundation of the nation. The ancients regarded "she" (she, a deity of the earth) and "ji" (ji, a deity of the grain). The combined "she" (she, a deity of the earth) and "ji" (ji, a deity of the grain) became a synonym for the nation.
[0003] The rice milling machine is mainly composed of a fixing wrench, a tightening nut wrench, a brush, a lower hopper, a grinding wheel, a wire brush, etc. The mechanical force generated by the mechanical equipment is used to peel and whiten the brown rice. The mechanical equipment used is called a rice milling machine. The rice milling machine is generally required in the processing of yellow millet.
[0004] When brown rice is milled, it will be mixed with a large amount of dust and small impurities of relatively light weight. However, the existing rice milling equipment lacks the function of dust and impurities removal. After the rice is milled, the brown rice will be mixed with dust and small impurities of relatively light weight, which will affect the quality of the finished product. It is also inconvenient to clean up later and affect the later sales and consumption of the yellow millet. Utility Model Content
[0005] The present application provides a rice milling machine for processing yellow millet to solve the problem of lack of dust and impurity removal functions.
[0006] The conveyor belt conveyor is provided with a conveyor belt conveyor, and a conveyor belt conveyor is provided on the conveyor belt conveyor.

[0013] Beneficial effects:
[0014] Taking into account the problem of lack of dust and impurity removal function, the air in the sealed collection box is extracted by energizing the vacuum pump, so that the negative pressure in the box is generated and suction is generated, and the dust and impurities mixed in the raw materials during the feeding process in the feed box 3 are sucked out through the impurity extraction pipe, the material guide pipe and the impurity feed hopper. After passing through the material blocking filter plate, they enter the sealed collection box from the impurity feed hopper and each group of pipes, and finally fall into the sealed drawer by gravity for collection. The turning motor is energized and started, and the drive wheel and the drive belt drive the turning shafts 6 to rotate on the turning bearings, so that the falling raw materials can be stirred and broken up to avoid the accumulation of raw materials, so that the scattered raw materials can be efficiently dusted and impurities removed, effectively solving the problem of the doping of impurities and dust affecting the raw materials.
