Description

Technical Field

[0001] The invention belongs to the technical field of forage harvesting, and in particular relates to a side-mounted mower and flattener for harvesting forage crops such as alfalfa. Background Art

[0002] Alfalfa is a globally cultivated forage crop with wide adaptability, high nutritional value and excellent palatability. It is known as the "king of forage grass" and occupies an important position in forage production. The moisture content and protein content of alfalfa stems, flowers and leaves are inconsistent. During the drying process, part of the protein is lost as the water evaporates. The conditioning treatment can break the nodes, crack the skin, flatten and bend the forage grass, which can eliminate the wax layer and cellulose on the surface of the alfalfa stem, accelerate water evaporation, and reduce the loss of nutrients. At present, the mechanization degree of alfalfa cutting and flattening in China has improved. Among them, the hilly and mountainous terrain is mainly based on the front hanging cutter, but there are problems such as unstable power transmission and imbalance of the whole machine during the harvesting operation.
