The invention discloses a high-speed distributor and application thereof. The distributor comprises a main ring beam device (I), a distributing bucket device (II), a water-cooled central charging pipe (1) and a distributor shell. The main ring beam device (I) comprises a main ring beam, a supporting trunnion (5) and a supporting long trunnion (20), wherein the supporting trunnion (5) and the supporting long trunnion (20) are supported on the distributor shell and are driven by an external transmission mechanism to swing. The distributing bucket device (II) comprises a bucket upper ring beam (16) and a bucket mouth (9), wherein the bucket mouth (9) is suspended on the bucket upper ring beam (16) and is connected with the main ring beam (15) through a short shaft connecting sleeve (17). A universal shaft device (11), a set of pull rods and the transmission device of the pull rods are arranged on the bucket upper ring beam (16), wherein the set of pull rods is arranged above the universal shaft device (11). The high-speed distributor can satisfy the requirements of distribution under normal temperature and under high temperature and has the advantages that the structure is compact, the transmission is stable, the cooling is convenient, the operation is reliable, the transmission efficiency is high, the maintenance and the inspection are simple, and the construction cost and the maintenance expense are saved.
