Unlike fossil fuels, biomass fuels are a new type of clean fuel.

The feeding device of the existing pellet fuel stove generally adopts a spiral pushing structure, and uses a spiral blade to deduce pellet fuel from one end of a material pipe to the other end so as to complete feeding. When the material is taken, the blade is required to scrape the particle fuel into the pusher, and when the particles are stacked and pressed or clamped, the material is easy to be clamped, so that the feeding is blocked.

In addition, the spiral pushing structure does not separate fuel in the pushing process, when large-gear feeding is performed, the fuel in the furnace is stacked more, the firepower is also large, the fuel in the feeding mechanism is easy to ignite, and even accidents caused by igniting the fuel tank occur.

Chinese patent CN209651213U discloses a screw feeder which is provided with anti-blocking blades, but cannot prevent the jamming phenomenon caused when the screw blades take materials. When a large fire is required, the fuel supply is relatively large, and the fuel at the discharge port may accumulate, so that there is a risk of igniting the fire to the fuel tank, and there is a safety risk. The above technical problems do exist in the prior art and are not solved.
