[0031] Four groups of slide grooves 3 are provided on the side of the rotating plate 27 close to the pushing folding strip 28, and a pair of sliders 31 are fixedly connected to the side of the pushing folding strip 28 close to the slide groove 3, and the sliders 31 are slidably connected to the inside of the slide groove 3; arc-shaped long blocks 41 are fixedly connected to both sides of the body 11, and arc-shaped short blocks 4 are fixedly connected to the outer sides of the pushing folding strip 28, and the arc-shaped short blocks 4 are slidably connected to the arc-shaped long blocks 41; springs 5 are fixedly connected between the long rods 24 of the same group; two annular outer plates 6 and two annular inner plates 61 are fixedly connected to the inner wall of the annular outer plate 6, and the half screen 25 is slidably connected to the inner wall of the annular outer plate 6; the side plate 13 away from the rotating plate 27 is fixedly connected to the motor 8, and the output end of the motor 8 passes through the side wall of the side plate 13 and is fixedly connected to the rotating plate 27.
[0032] In this embodiment, the rotation of the crushing roller 2 is controlled to crush the biomass raw material. The crushed small biomass particles fall downward into the heating box 12 through the sieve holes of the half screen 25. The larger biomass particles cannot pass through the sieve holes. By starting the motor 8, the motor 8 drives the rotating plate 27 to rotate through the output end. Under the limiting action of the slide 3, the rotating plate 27 drives the pushing folding bar 28 to rotate through the slider 31. Under the limiting action of the inner groove 22 and the outer groove 21, the pushing folding bar 28 drives the opening and closing plate 26 and the half screen 25 to rotate through the two long rods 24.

Under the action of gravity, the larger particles fall downward, and the crushing roller 2 is controlled to perform secondary crushing on the larger particles, so that the larger particles are crushed into multiple small particles, so that the crushed small particles fall downward through the sieve holes of the half-sieve 25 into the heating box 12. The crushed biomass particles are screened by setting two half-sieves 25, so that the size of the biomass particles inside the heating box 12 is uniform, so that the heat is evenly distributed inside the particles, and the particles are completely carbonized.
