[0017] A support plate 12 for supporting the loading hopper 11 is fixedly installed at one end of the top of the fixed frame 9, and two second threaded shafts 13 are rotatably connected to one end of the interior of the fixed frame 9. The surfaces of the two second threaded shafts 13 are threadedly connected to movable push blocks 14. The tops of the two movable push blocks 14 are rotatably connected to the bottom of the loading hopper 11 by support rods 15. A fixed plate 16 is fixedly installed inside the fixed frame 9 and is in sliding contact with the two movable push blocks 14. One end of the two second threaded shafts 13 is fixedly connected to a small bevel gear 17, so that the loading hopper 11 can be effectively rotatably adjusted; one end on both sides of the fixed frame 9 is rotatable The two ends of the two rotating shafts 18 located inside the fixed frame 9 are fixedly connected with large bevel gears 19, and the two large bevel gears 19 are respectively meshed with two small bevel gears 17.
