Description

Technical Field

[0001] The utility model relates to an agricultural machine, in particular to an agricultural machine for mowing crops. Background Art

[0002] Crops are various plants cultivated in agriculture, including food crops and cash crops (oil crops, vegetable crops, flowers, grasses, and trees). "Food is the primary need of man", which expresses the relationship between man and food. A reasonable diet can bring health to human beings. The growth of crops is inseparable from scientific and technological production technologies, as well as mechanical equipment manufactured by new industries to assist agricultural production.

[0003] After the growth of grain crops is completed, their fruits are harvested. Generally, mechanical agricultural machinery is needed for harvesting. After the fruits are harvested, the root straw of the crops will remain in the field. The straw itself rots relatively slowly. In order to better cut the straw and make the land more quickly for the cultivation of other crops, a crop cutting agricultural machinery that can more conveniently cut the straw is also needed.

[0004] The current crop-cutting agricultural machinery cuts the straw from the land, passes the straw through the crushing roller inside the agricultural machinery and then discharges it. Due to the different lengths of the straw, direct crushing will not be thorough, so that some straw cannot be completely crushed. Utility Model Content
