A kind of separator for seed cotton

Abstract

The seed cotton separator of the present invention is characterized in that it includes a feed bin, an impurity settling bin, a suction duct, a dust cage and a driving device, the top of the feed bin is provided with a seed cotton feed channel, and the lower part is provided with a discharge Material wind protection valve, a rotating net dust cage is installed in the feeding bin, and the outer side of the rotating net dust cage is a perforated plate connecting the suction pipe and the feeding bin; a miscellaneous orifice plate is arranged between the feeding bin and the impurity settlement bin , there is a through-hole on the orifice plate for the removal of impurities, and a wind-removal valve for the removal of impurities is provided at the bottom of the impurity sedimentation bin; The seed cotton in the silo undergoes foreign matter removal. The separator for seed cotton removal of the present invention facilitates the entry of external seed cotton into the feed bin under the negative pressure environment of the feed bin, and the impurities in the seed cotton enter the impurity settlement bin through the through holes on the trash removal orifice plate, The removal of impurities in the seed cotton is realized, the beneficial effect is remarkable, and the method is convenient for application and popularization.

Description

technical field [0001] The present invention relates to a separator for removing impurities from seed cotton, more specifically, to a separator for removing impurities from seed cotton which has a large processing capacity and can discharge more impurities in the seed cotton. Background technique [0002] At present, there are two types of seed cotton separators used in our country: rotating screen separators and fixed screen separators. Due to structural limitations, the output of fixed screen separators cannot meet the current market needs and has been basically eliminated. The rotary screen separator works well as a seed cotton unloader. Due to the increase in labor costs and the expansion of the planting area, the existing cotton planting is usually picked by machines. Compared with manual cotton picking, machine-picked cotton has lower impurity content higher. For the impurities with high content in machine-picked cotton, the existing rotary screen separator can no lon...

Problems solved by technology

[0002] At present, there are two kinds of seed cotton separators used in our country: rotating net separator and fixed net separator. Due to structural limitations, the output of fixed net separator cannot meet the current market needs and has been basically eliminated.

The rotary screen separator works well as a seed cotton unloader. Due to the increase in labor costs and the expansion of the planting area, the existing cotton planting is usually picked by machines. Compared with manual cotton picking, machine-picked cotton has lower impurity content higher

For the high content of impurities in machine-picked cotton, it is impossible to discharge more impurities by using the existing rotary screen separator
