The lower portion of the swing plate 2 is hingedly connected to an extension and pushing member 4. The extension and pushing member 4 is connected to the rack 9 and is used for driving the swing plate 2 to vertically swing to adjust the discharging speed. The lifting guide plate 3 is slidably connected to the rack 9 in the up-down direction and is used for contacting the lower edge of the swing plate 2 to receive the ore materials discharged from the swing plate 2 and guide the ore materials to the conveying belt 91.

[0034] Compared with the prior art, the belt feeding device provided by the present embodiment utilizes the material supporting plate 1 to guide the ore materials in the hopper 8, so that the ore materials fall onto the lifting guide plate 3 through the swing plate 2.
