A combined cleaning sift

Abstract

The invention relates to a combine clean screen, which comprises upper select box and lower screen box. Wherein, two boxes are connected via diverter; the upper box has gravity selecting table; the lower box has flat screen; the selecting table is made from the screen plate with fish scale-shaped screen holes; the table is incline; the selecting table has fan under; the selecting table, fan and flat screen are driven by motor. The invention can separate heavy and light foreigner at one time. And the whole device is driven by one motor, with small volume and low power consumption.

Description

technical field [0001] The invention relates to a grain machine, in particular to a combined cleaning sieve used in grain deep processing enterprises and for grain cleaning before storage. Background technique [0002] After rice and other grains are harvested, there are many weeds, straw, rope ends, bricks, stones, glass fragments and other sundries mixed in. According to the quality of the sundries, they are divided into light miscellaneous (weeds, small straw, rope First-class) and heavy miscellaneous (bricks, stones, broken glass, etc.) grain processing enterprises should conduct preliminary cleaning before deep processing. At present, the cleaning equipment in grain machinery is classified according to its function, mainly including winnowing, screening, gravity sorting and other equipment. Different equipment has different performance and characteristics, and each has its own shortcomings. For example: winnowing equipment, the main function is to separate the light im...

Problems solved by technology

Due to the above reasons, many enterprises often pay attention to the cleaning of heavy impurities. In this way, light impurities such as short straw, rags, hemp rope, shriveled grains, etc. will be mixed in the grain. The feeding mechanism of the machine is often blocked, making the feeding uneven, reducing the process effect of the equipment, and affecting the processing capacity

[0004] How to remove heavy impurities and light impurities at the same time is a problem that has long plagued rice processing enterprises to balance the front and rear processes, reduce equipment no-load time, and improve work efficiency.
