The invention relates to a fully mechanized caving face inter-frame coal leakage resource recovery device which comprises a main body base, a first hydraulic rod is fixedly connected to the top end of the inner side of the main body base, a main top plate is fixedly connected to the top output end of the first hydraulic rod, and a front top plate is hinged to one end of the main top plate. The device effectively solves the problems of coal leakage and waste rock leakage in a bracket gap during bracket descending and moving of a fully mechanized caving face, and through ingenious design of the device, leaked coal briquettes can be effectively collected and guided to a conveyor, so that the situation that the coal briquettes fall into the front of the bracket and a cable trough is greatly reduced, the recovery rate of coal resources is remarkably improved, and the production cost is reduced. And the whole device is simple in structure, convenient to operate and suitable for production environments of various fu
