Biomass fuel particle rotary vibration sieve

The utility model belongs to the technical field of spin-vibration screen equipment, and particularly relates to a biomass fuel particle spin-vibration screen which comprises a spin-vibration screen base, a screening frame is installed on the spin-vibration screen base, three arc-shaped grooves are formed in the side wall of the screening frame, the three arc-shaped grooves are arranged in an array mode, stirring assemblies are arranged in all the arc-shaped grooves, and the stirring assemblies are connected with the screening frame. The stirring assembly comprises a rotating rod, the rotating rod is located in the arc-shaped groove and rotationally connected with the screening frame, and a torsional spring is arranged at the joint of the rotating rod and the screening frame. The arc-shaped poke rod rotates to poke particles gathered at the edge to the middle, so that the screening speed is improved, the situation that the particles are scattered towards the edge due to vibration, the particles are gathered a
