[0024] The front end of the top side of the bottom plate 1 is fixedly connected with a support frame 16, and the left and right ends of the support frame 16 are rotatably connected with a cylinder 12, and the driving end of the cylinder 12 is rotatably connected to the front end of the side plate 11. The angle of the front end of the conveyor belt 9 can be adjusted at will through the cylinder 12 under the conveyor belt 9, so as to adapt to the height of the feed port of different calcining machines, so that the machine can be used more widely and more efficiently.

[0025] Two motors 8 are arranged inside the support frame 2, and the driving end of the motor 8 is connected to the rocker 17, and the non-driving end of the motor 8 is connected to the inner wall of the support frame 2 through the fixed frame.
