Anti-winding type straw crushing device

The utility model relates to an agricultural machine, in particular to a miniature machinery through which the crops straw, corn, etc. are fodder chopped, kneaded and smashed to crude/fine feeds or processed to biomass fuel materials. The utility model is characterized in that: the agricultural machine is provided with a kneading machine casing and a crushing machine casing and is connected with a fan in the rear side. After being fodder chopped into sections by the cutter in the kneading machine casing, the materials (such as straw) are turned into the strip materials under the functions of hammer piece and rack in the machine casing, the lighter powders are blown into the crushing machine casing by the air flow of the fan to be further clashed and smashed under the functions of the hammer piece and an annual screen. The machine avoids the possibility of twisting the straw on the axial for installing the anti-twisting frame plate and ensures that the work efficiency is enhanced for adopting the special round
