[0024] Given by Figures 1 to 3 The width of the top conveyor belt 8 is smaller than that of the bottom conveyor belt 2. Vertical limiting rods 10 that penetrate through and are slidably connected to the L-shaped support frame 5 are fixedly arranged at both ends of the top of the lifting support frame 7. Both the grinding assembly one 3 and the grinding assembly two 4 are composed of a movable support seat 11, a grinding motor 12, a grinding disc 13, and a telescopic cylinder 14.
