The invention provides an efficient bulk material truck loading device. The efficient bulk material truck loading device comprises a flange connector used for being in butt joint with a feed opening,a cavity and a cone, wherein the upper end of the cavity is connected with the flange connector, a discharge opening is formed in the lower end of the cavity, and the cone is arranged below the discharge opening in the mode that the vertex of the cone faces up, and used for converting movement of granular bulk materials which fall off from the discharge opening in the vertical direction into oblique throw movement towards all directions. The efficient bulk material truck loading device changes the falling movement of the bulk materials in the direction of the gravity into the material throw movement in the direction of the cone, can sprinkle the bulk materials to a far area, enables the bulk materials to be even in overall distribution, reduces the quantity of charging ports in a chargingcontainer, and even can only form one charging port.
