The invention discloses a rotating and sliding integrated type double-function movable head cover. The movable head cover comprises a lower layer head cover, upper layer head covers, lower layer head cover transmission devices and an upper layer head cover driving device; the lower layer head cover transmission devices are fixed to the tops of end walls and connected with the lower layer head cover, and the roof of a hopper wagon is made to form a charging opening to be opened or closed by moving the lower layer head cover through the lower layer head cover transmission devices; multiple charging openings are formed in the lower layer head cover in the wagon body direction, the upper layer head covers are slidably arranged on the lower layer head cover, the upper layer head cover driving device is connected with the upper layer head covers, and the charging openings formed in the lower layer head cover are made to be opened or closed by moving the upper layer head covers through the upper layer head cover driving device. According to the rotating and sliding integrated type double-function movable head cover, the mode of matching the upper layer head covers with the lower layer head cover is adopted, the upper layer head covers and the lower layer head cover have different applications, therefore, the functions of loading and transporting large-particle goods and dust-particle goods can be simultaneously achieved by means of a same goods wagon, good universality is achieved, the vehicle use ratio is increased, and the market diversification requirement is met.
