The utility model provides a flap-type vacuum leakage prevention device for a crawler-type vacuum suction filter. The flap-type vacuum leakage prevention device comprises a vacuum suction filter, wherein the vacuum suction filter comprises a rack, a motor, rolling wheels and a crawler belt; the rolling wheels are mounted on the rack; the crawler belt is arranged on the rolling wheels; filter cloth covers the outer layer of the crawler belt; a material distributor is arranged at one end of the upper side of the crawler belt. The flap-type vacuum leakage prevention device is characterized in that three groups of vacuum boxes are arranged on the lower side of the crawler belt along a motion direction of the crawler belt and are connected with a vacuum pump through a vacuum pipe; a flapping device is arranged above a second-level vacuum box and a third-level vacuum box; the flapping device comprises flapping equipment and a vibration motor; the flapping equipment is connected with the vibration motor through a driving mechanism. The flap-type vacuum leakage prevention device has the advantages and benefits that the materials can be flapped by using the flapping equipment when the materials are cracked, crevices produced by pressing the materials can be re-filled and are flattened so as to guarantee the sealing without the loss of the vacuum, thus guaranteeing the dehydration effect; the vibration motor can adjust exciting force according to requirements, and the deformation of the materials is avoided.
