What driver's license do cotton pickers need ~

The cotton picker's card is not a driver's license, but an operation certificate, which is issued by the labor department or the agricultural machinery department. The cotton picker's operation certificate is a special vehicle driver's license and he can't drive. With the approval of the Ministry of Labor or the Safety Supervision Bureau, we have formal operation certificates (also known as employment certificates and IC card certificates), skill certificates and various certification certificates.

How to use cotton picker;

When picking cotton, first carry the battery, fasten the cotton bag, and then connect the back end of the circular tube of a 50 cm cotton picker into the cotton bag, and the front end has a multi-directional cotton picking head, which has the dual functions of picking cotton and guiding seed cotton into the cotton bag. When operating in the field, just turn on the power switch and aim at the cotton peach, that is, the whole process of picking and guiding cotton is automatically completed.

Take down the spindle with rotating teeth, grab the seed fiber from the blooming cotton peach, and send it into the cotton box by air flow. There are mainly two kinds of cotton pickers: the horizontal spindle picker used in the United States has high cotton picking rate, but its structure is complex, manufacturing accuracy is high and cost is high.

The Soviet Union mostly adopts vertical spindle cotton picker, which has simple structure and low cost, but the cotton picking rate is low, and there are many cotton that fall to the ground, which is very harmful to cotton plants. The impurity content of machine-picked seed cotton is high, and its quality grade is obviously lower than that of hand-picked seed cotton. Machine-picked seed cotton needs a complete set of cotton cleaning equipment, and the picked cotton can be used as textile raw materials after repeated cleaning before and after ginning.
