The invention relates to a robot, in particular to an intelligent robot capable of preparing biomass fuel through straw. The intelligent robot capable of preparing the biomass fuel through the straw comprises a dust collecting box, a dust removal hand, a burning furnace, a heat guide pipe, a treatment box, a wind box, a rolling cylinder and a conveying cylinder. The elastic potential energy of rotary springs is utilized to enable a blocking door to be automatically opened when the straw is added, the blocking door can be automatically closed after filling of the straw is completed; the rotation of a cam is utilized to enable a dreg discharging plate to vibrate up and down, dregs can be better discharged through dreg discharging openings after burning of the straw, and the straw is enabledto be sufficiently burned; dregs discharged away and out through the dreg discharging openings can be cleaned away by pulling a braking part; oxygen in the main body of the burning furnace is furtheradded while a fan transmits hot gas, and the straw is sufficiently burned; and gas produced after burning of the straw is treated by an activated carbon filtering screen, and the activated carbon filtering screen in a slidable filter screen installation frame is convenient to change.
