The invention discloses an opening manner of a loading opening cover of a railway grain vehicle. The loading opening cover of the railway grain vehicle is opened in two manners of manual opening and pneumatic opening, an air cylinder driving rod is connected to transmission chains of the loading opening cover of the railway grain vehicle which is opened in the manner of manual opening, under the effect of an air cylinder, and the transmission chains are driven to rotate by the upward operation and the downward operation of the air cylinder driving rod, so that the opening or the closing of the loading opening cover of the railway grain vehicle is driven by a chain transmission mechanism. According to the opening method and the opening device, which are disclosed by the invention, an manual opening device and a pneumatic opening device are jointly adopted to open the loading opening cover of the railway grain vehicle, so that the other set of the opening device can be opened to operate in time when one set of the opening device is faulted, the phenomenon that the loading opening cover of the railway grain vehicle cannot be opened because the opening device is faulted is avoided, the selection of an operator is facilitated, and opening the loading opening cover of the railway grain vehicle is facilitated.
