NOVELTY - A cutting mechanism comprises a scraper (2) and a scraper driving device. The shape of the cover (1) is cylindrical. The bottom of the barrel cover is opened with a first through-hole axis of the first through hole (3). The scraper driving device comprises motor (5), large gear (6) and large gear connecting rod (7). Gear connecting rods are connected and covered the bottom of the barrel. The center gear of the second through hole (9) is opened. A motor output shaft (8) is connected to the pinion.    USE - Cutting mechanism used for biomass granule granulator.    DETAILED DESCRIPTION - A cutting mechanism comprises a scraper (2) and a scraper driving device. The shape of the cover (1) is cylindrical. The bottom of the barrel cover is opened with a first through-hole axis of the first through hole (3) coincident with the axis line and covering the inner diameter of the first through-hole and biomass particles made same granulator feed cover outer diameter. The inner diameter of the open end of the barrel cover is greater than the blade drive device package. The scraper driving device comprises motor (5), large gear (6) and large gear connecting rod. Large gear and a large gear connection lever position in the cover inside. Gear connecting rods (7) are connected and covered the bottom of the barrel, and the distribution in the outer edge of the first through-hole, to center symmetry; end of each connecting rod is connected to T-shaped rollers. The center gear of the second through hole (9) is opened. The aperture of the second through-hole is not smaller than an aperture through hole. Gear provided on one surface section of inverted T-shaped annular groove. The T-shaped rollers are embedded in the annular groove, and T-shaped rollers are fitted slidably connected with the annular groove. A scraper is attached to the large gear on the other surface. A motor output shaft (8) is connected to the pinion. Pinion wheel and gear comprise the gear pair. The scraper with the big gear in the biomass particles rotate between the inner wall of the granulator scraper ring mold outer wall of the barrel cover blade track mouth of a ring. The ring and biomass granulation machine correspond to the location of the outer wall of the ring mold.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram of the cutting mechanism.
