Agricultural grain efficient vibration screening machine

Abstract

The invention relates to the field of agricultural grain treatment equipment, in particular to an agricultural grain efficient vibration screening machine. The agricultural grain efficient vibration screening machine comprises a screen box main body, a supporting frame and vibration motors, the screen box main body is fixedly arranged on the supporting frame, a first screen and a second screen arearranged in the screen box main body, a material inlet is formed in one end of the screen box main body, the material inlet is opened upwards and communicates with the screen box main body, and the pair of vibration motors are provided and fixedly arranged on the two sides of the screen box main body correspondingly. Grains are poured from the material inlet, the vibration motors are started, thematerials are thrown up and jump forwards on the first screen and the second screen to do linear motion, so that the purpose of screening and grading the materials is achieved, the grains and smallerimpurities can fall into the second screen below the first screen through the first screen, the larger impurities can be left on the first screen, the smaller impurities can fall below the second screen through the second screen, and grain particles can be left on the second screen; and the agricultural grain efficient vibration screening machine is compact in structure, convenient to operate andobvious in dust removal and impurity removal efficiency.

Description

technical field [0001] The invention relates to the field of agricultural grain processing equipment, in particular to a high-efficiency vibration screening machine for agricultural grain. Background technique [0002] Grain refers to the general term for various plant seeds in cooking food, also known as "grain", which is rich in nutrients, mainly protein, vitamins, dietary fiber, fat, etc. my country is a big agricultural country, and food has a vital influence. After the grain is harvested, many impurities will be mixed in it, such as small stones, soil clods, weed clippings, etc., which will affect the purity and quality of the grain, which is not conducive to preservation and use. [0003] A double-deck grain screening device disclosed in Chinese Patent No. CN207981587 U is characterized in that it includes an inner screen drum for screening large debris, an outer screen drum for screening small debris, and an outer screen drum for driving the inner screen drum and the...

Problems solved by technology

[0004] Since the grain will be mixed with tiny impurities such as dust and grass clippings, these impurities will fly into the air during screening, causing pollution to the working environment. The organic impurities in them may cause dust explosions. , it will also cause the food to heat up, mildew and deteriorate; afte
