The output end of the driving motor 501 is fixedly connected to a rotating shaft 502, which passes through the top of the crushing barrel 4 and extends to the inside to be rotatably connected to the bottom end of the crushing barrel 4. The outer surface of the rotating shaft 502 is fixedly connected to a cutting blade 503, and the bottom end of the outer surface of the rotating shaft 502 is fixedly connected to three grinding rods 504. The three grinding rods 504 are arranged in an annular array and abut against the inner bottom surface of the crushing barrel 4. The bottom end of the crushing barrel 4 is provided with a plurality of drop holes 505 in an annular array. Through the crushing component 5, the driving motor 501 is The motor 501 is started, so that the output end of the driving motor 501 drives the rotating rod 502 to rotate, so that the rotating rod 502 drives the cutting blade 503 and the grinding rod 504 to rotate, so that the biomass enters the crushing barrel 4 through the rectangular feed port 6, and the biomass is cut by the cutting blade 503.
