Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a cotton stalk pulling machine. Background technique

[0002] Due to the high labor intensity and low efficiency of manual harvesting of cotton stalks, the large output of cotton stalks, the dispersion, and the strong seasonality of collection and storage, under the current production mode, except for some of the cotton stalks returned to the field, the remaining cotton stalks are discarded or burned at will. Not only does it cause a huge waste of cotton stalk resources, but burning cotton stalks will destroy the soil structure and seriously pollute the environment; at the same time, due to the shortage of labor and the lack of suitable matching field cotton stalk harvesting machinery, it is difficult to harvest, store and transport cotton stalks , high cost, seriously restricting the utilization of cotton stalk resources. Cotton stalk mechanized harvesting techno...
