An Airborne Cotton Fiber Loss Suppression and Efficient Cotton Cleaning Device

Abstract

The invention relates to a vehicle-mounted anti-loss efficient scutching device of cotton fibers and belongs to the technical field of agricultural machinery. The vehicle-mounted anti-loss efficient scutching device comprises a first-grade pin roll, a second-grade pin roll and a third-grade pin roll. An upper brush, a middle brush, a lower brush and patting rods distributed at intervals are arranged on one side of the scutching device. An upper brush roll is installed below the first-grade pin roll, a lower brush roll with brush hair contacting the lower brush roll and the outer circle of the third-grade pin roll is installed below the second-grade pin roll, and an arc barrier is arranged on the lower side of the third-grade pin roll. A cotton collection runner for conveying airflow from bottom to top is arranged in a casing on one side far away from the patting rods, and an upper suction port and a lower suction port are formed on the cotton collection runner. The bottom of the cotton collection runner is connected with an air outlet of a cotton conveying fan. The vehicle-mounted anti-loss efficient scutching device achieves three-grade reasonable impurity clearing of seed cotton according to the proportion, thereby avoiding repeated clearing, remarkably reducing damage of cotton fibers, improving the impurity clearing effect and making the impurity rate to be lower than 10%; meanwhile strengthens the recycle effect and greatly reduces seed cotton loss.

Description

technical field [0001] The invention relates to a device for cleaning impurities in cotton, in particular to an airborne cotton fiber damage suppression and high-efficiency cleaning device, which belongs to the technical field of agricultural machinery. Background technique [0002] Cotton harvesters can be divided into two types according to the harvesting method: one is a selective harvester, and the other is a unified harvester. Harvesters are further divided into large spindle picking and small air suction. The air-suction type is only suitable for a family of small-area growers, and the promotion value is not high, and almost no one uses it. Due to the high cost of large-scale picking spindles, the high cost of use and maintenance limits its application range. It is only used when economic conditions permit. The Xinjiang Corps with a large cotton planting area is widely used, and the local use is less. The unified harvester has the advantages of simple structure, low ...

AI Technical Summary

Problems solved by technology

[0006] Practice has proved that the device is effective in solving incomplete separation of seed cotton, clogging of the miscellaneous outlet and improving the cleaning efficiency. However, it is difficult to reduce the impurity rate, and the loss rate of the impurity removal is too high; the impurity removal process has to be repeated, so it is easy to damage the cotton fiber

In addition, there are also problems such as poor cleaning effect of cotton stalks, easy to cause blockage and affect normal operation, and discharge of micro impurities into the air, which can easily cause secondary pollution of seed cotton
