Cotton fibre is wrapped around moistened spindles and then removed by a unique mechanism known as a doffer, from which it is transferred to a huge basket carried above the machine. The spindles are coupled to a drum that rotates at the same time as the spindles, causing the spindles to enter the plant. Ii) Picker harvesters, also known as spindle harvesters, take cotton from open bolls while leaving the bur on the plant.

After the green vegetative growth has been killed by frost, strippers work best.

The undesirable material is subsequently removed at the gin using specific machines. I) Stripper harvesters remove both open and unopened bolls, as well as many leaves and stems, from the entire plant. Strippers and pickers are the two most common mechanical cotton harvesters: Spindles on cotton-picking machines pick (twist) seed cotton from burrs attached to plant stems. Then, either a picker or a stripper is used to harvest the crop. The plants produce pink and cream blooms that fade after pollination and are replaced with cotton bolls, which are a type of fruit. Harvesting is not only one of the last but also one of the most crucial processes in the development of cotton crops.Ĭotton harvesting - Cotton seeds are sown in the spring and grow into green, bushy shrubs that reach a height of one meter.
