The invention discloses a spreading and unloading all-in-one machine and a spreading and unloading method, and belongs to the technical field of sludge treatment. The spreading and unloading method comprises the following steps: winding filter cloth on a cloth roller, and rotating the cloth roller; the grating is started, the width of the filter cloth is measured, the front end of the spreading mechanism abuts against the filter cloth to advance forwards to spread the filter cloth, and the spreading mechanism retreats to spread the filter cloth; the spreading mechanism reciprocates until spreading is completed, and the grating obtains the average width of the filter cloth; the lifting shaft is lifted to a second position, and the cloth roller rotates to drive the filter cloth to roll back; and the grating feeds back the average width of the filter cloth to the stepping motor, the deviation rectifying photoelectric switch moves to a proper position, and the filter cloth is rolled at the center position of the
