Grate ash removal structure for biomass boiler

The utility model relates to the technical field of fire grates, and discloses a biomass boiler fire grate deashing structure which comprises a base, the left side and the right side of the interior of the base are of hollow structures, a first motor is connected to the middle of the left side of the interior of the base in an inserted mode, and a rotor of the first motor is coaxially and fixedly connected with a first cam. A transmission insertion block is inserted into the right side of the interior of the base, a U-shaped support is fixedly connected to the top of the transmission insertion block, and fire grate bodies are fixedly installed at the top ends of the supporting plates. According to the fire grate ash removal structure for the biomass boiler, a first motor drives a first cam to rotate, so that a transmission connecting rod can drive a transmission inserting block to move left and right, then the first motor and a U-shaped support can reciprocate left and right under the action of a spring, and
