The invention relates to a shipping device reducer of a continuous miner, and the main structure is composed of a casing, a case, a big bevel gear, a medium bevel gear, a small bevel gear, a planetary gear, a transmission angle gear, an output angle gear, a transition wheel, a spline shaft, and a bearing. The invention uses a totally-sealed design, adopts the big, medium and small bevel gears forshifting, the planetary gear for shifting and transmission, the output angle gear for shifting, the transition wheel for transmitting to form multi-level multi-mode shifting to lead the transmission speed to reach 27.5:1 in the end and form a single-input and double-output structure. The reducer has the advantages of advanced and reasonable design, compact structure, safety and reliability, excellent transmission performance, and stable shifting and running, and is an ideal shipping device reducer of the continuous miner. In addition, the reducer also can be used in other similar equipment for shifting.
