Description

[0002] Green fodder (also called green fodder, green fodder) refers to the fresh stems and leaves of plants that can be used as feed. It is named because it is rich in chlorophyll. Green fodder harvester refers to an agricultural machinery device mainly used to harvest low-lying green crops such as green forage, oats, and beet stems and leaves. Its main working part is a rotary chopper equipped with multiple fling knives. The green fodder harvester is actually an organic combination of a chopper and a prefix, which completes the field harvesting process of green fodder. The process is to produce green fodder growing in the field into green fragments.

[0003] The existing silage harvester usually gathers the harvested green fodder through the pole on the top of the harvesting table when in use, so as to reduce the green fodder from tipping over to the sides of the harvester during the harvesting process, so as to improve the harvesting efficiency.
