The invention relates to a pigging object emitter. The pigging object emitter comprises a control valve and a storage cylinder. A one-way valve is arranged in a pipe; a one-way valve is arranged is arranged in a bypass branch pipe communicated with the pipe; and the one-way valves are connected with the storage cylinder. A plurality of pigging objects are arranged in a cavity of the storage cylinder. A riser pipe communicated with the storage cylinder is arranged on the upper part of the storage cylinder in the perpendicular direction; a cover plate is arranged on the upper part of the riser pipe; a gasket is arranged between the cover plate and the riser pipe; and the cover plate and the riser pipe are connected into a whole through a screw. The cover plate is provided with a plurality ofkeyway threaded holes; and a plurality of rapid rotating pins penetrate into the storage cylinder through the keyway threaded holes and are fixed. A one-way valve is connected between the storage cylinder and the pipe; and a pigging object emitter circuit is formed through the connections. The pigging object emitter has simple operation and easy part replacement, cleans the pipe during the production process, reduces the possibility of underwater leakage, and greatly reduces the equipment cost. The application range of the pigging object emitter is extended from land to underwater areas including deep water areas and ultra-deep water areas.
