Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to a cotton stalk cutting and collecting device. Background Art

[0002] Cotton is an important economic crop in my country. There are several ways to deal with cotton stalks. One is incineration, but with the requirements of environmental protection, incineration has been banned; the first is to crush and return to the field, which will cause a large amount of waste of cotton stalks, and after years of operation, the cotton stalks returned to the field will also affect the planting in the new year; the third is to recycle the cotton stalks and then further process them. Although this can avoid the harm caused by the first two treatments, there are certain problems with cotton stalk recycling. For example, cotton stalks have a certain moisture content. If they are cut and recycled immediately, the moisture content is high and cannot meet the needs of further processing. In addition, there is a situation where the cotton stalks ferment due to the high moisture content. If the cotton stalks can be cut and placed in the field to dry to reduce the moisture content, the impact caused by the high moisture content can be avoided.
