[0002] Biomass straw refers to the stalks, leaves and other plant residues left after the harvest of crops, which can be used for biomass energy production. Biomass straw can be used to produce biomass fuel, biomass charcoal, biomass alcohol, etc., which helps to reduce dependence on fossil energy, and is also beneficial to the resource utilization of farmland and environmental protection. The use of biomass straw is of great significance to promoting sustainable agricultural development and achieving clean energy goals.

[0003] Biomass straw is usually crushed before being used. Traditional biomass straw crushing equipment directly crushes the straw by rotating cutting knives.
