The following is a detailed description taking the upper outer roller 2 of the inlet, the upper inner roller 3 of the inlet and the upper height adjustment mechanism 10 of the inlet as an example.

[0020] The upper inlet outer roller 2, the upper inlet inner roller 3, and the upper inlet height adjustment mechanism 10 are installed on the upper inlet of the frame 1. There are two rollers: the upper inlet outer roller 2 and the upper inlet inner roller 3 (the roller closest to the vertical plane of the equipment centerline is defined as the inner roller, and the roller away from the vertical plane of the equipment centerline is defined as the outer roller). The two rollers can be adjusted in height together, and the two rollers can also be adjusted independently in the horizontal plane perpendicular to the direction of material feeding and discharging. The angle between the two roller axes and the horizontal plane can be adjusted independently within a 90° range.

[0021] The inlet upper height adjustment mechanism 10 is shared by the inlet upper outer roller 2 and the inlet upper inner roller 3. The inlet upper outer roller 2 and the inlet upper inner roller 3 each have an independent horizontal plane position adjustment mechanism 14, a swing angle adjustment mechanism 15 and a rotation drive mechanism 16.

[0022] The inlet upper height adjustment mechanism 10 includes two components each of a worm gear case 44, a worm nut 39, a worm 40, a lifting screw 38, a worm cover 43, and a lifting rail 37; four components each of a thrust ball bearing 42, a tapered bearing 45, a worm cover 46, and a lifting slider 36; and one component each of a lifting reduction motor 41, a drive shaft 47, and a floating seat 35. The worm gear case 44 is mounted to the frame 1 via a key and screws. The worm nut 39 is mounted within the worm gear case 44 via the thrust ball bearing 42 and the worm cover 43.
