A translation type grain hopper car top cover, comprising a cover body (1) located at a loading opening of a car body. One side of the cover body is hinged to a crank throw (12), the crank throw is connected to a transmission shaft (2) rotating in the car body, the other side of the cover body is hinged to a connecting lever (11), the connecting lever is hinged to the car body, and the transmission shaft is connected to a driving mechanism. The present invention provides a top cover which is convenient in operation, so as to effectively solve the problems in the prior art that the working efficiency is low, and the operation safety is poor. When the top cover is in a closed state, a self-locking air cylinder (9) guarantees a vertical locking capacity thereof, a longitudinal stopper (6) guarantees a longitudinal locking capacity thereof, and a locking base (7) and a locking rod guarantee a transverse locking capacity thereof. A four-connecting-rod mechanism is formed among the car body, the crank throw, the connecting lever and the cover body, translation type opening and closing of the cover body are achieved, and space occupation is reduced.
