By the middle of the next century, various biomass alternative fuels produced by new technologies will account for more than 40% of the world's total energy consumption. Straw is one of the biomass raw materials, and straw needs to be compressed after harvesting for easy transportation. The existing straw compression device directly compresses the straw. Since the straw is long and short, direct compression will result in unevenness.
