[0002] Biomass fuel refers to burning biomass material as fuel, generally mainly is forestry waste. The main difference lies in fossil fuel. In the current national policy and environmental protection standard, direct combustion of biomass belongs to high-pollution fuel, only used in rural large stove, not allowed to use in the city. The application of biomass fuel is mainly biomass briquette, which is made of forestry waste as raw material, such as yellow stem, branch and leaf powder, bark, etc. After crushing, mixing, extruding and drying, various shaped (such as block, granular) new clean fuel can be directly combusted.

[0003] The existing patent with application number CN 202323026275.6 discloses a biomass raw material crushing and impurity removal mechanism. Impurities are screened by vibrating screen on the vibrating plate, adsorbed into the collection bin, and filtered by the filter screen on the filter frame to reduce the impurity content in the biomass crushed material and improve the crushing quality. However, the filter screen is used to remove impurities from the biomass raw material, and the impurities are easily blocked in the filter screen mesh, which is inconvenient to clean and affects the impurity removal effect. The vibration noise generated by the motor driving the filter screen is large.

[0004] It should be noted that the above content belongs to the technical cognition of the inventor and does not necessarily constitute prior art. CONTENT OF THE UTILITY MODEL
