Specifically, the base frame 1 is provided with a first discharge port 11 opposite to the discharge channel 76 and a second discharge port 12 located behind the first discharge port 11. The second discharge port 12 is located behind the material conveyor roller 73. When the material falls downward from the discharge end of the second belt conveyor 3, the air blown out by the second air outlet pipe 64 flows in the same direction as the conveying direction, blowing the light substances in the material backward, passing through the material roller 73 and entering the second discharge port 12, and then entering the corresponding hopper for storage. The material after removing the light substances continues to fall downward from the discharge channel 76 into the first discharge port 11, and then enters the corresponding hopper for storage. Furthermore, the rotating component includes a rotating motor connected to one end of the material conveyor roller 73, and the other end of the material conveyor roller 73 is supported on the support frame 74 by a bearing.

[0030] The movable assembly 75 connects to and drives the relative support frame 74 to move in the movable slot 711. It includes a movable seat 751 disposed on the side of the air separator 71 opposite to the support frame 74, a movable lead screw 752 disposed on the movable seat 751 and connected to the relative support frame 74, a positioning nut 753 that cooperates with the movable lead screw 752 and can be fixed on the movable seat 751, and a fixing member 754 for fixing the support frame 74.

[0031] The first mounting frame 8 and the second mounting frame 9 are movably connected by a first connector 81 and a second connector 82 that are spaced apart. The first connector 81 and the second connector 82 are spaced apart along the material conveying direction. The first connector 81 includes a first connecting seat 811 disposed on the second mounting frame 9 and a first connecting block 812 disposed at the bottom of the first mounting frame 8 and movably connected to the first connecting seat 811.

[0032] The second connecting member 82 includes a second connecting seat 821 disposed on the top of the second mounting bracket 9, a connecting sleeve 822 extending upwardly connected to the second connecting seat 821, a second connecting block 823 disposed on the first mounting bracket 8 opposite to the second connecting seat 821, a connecting rod 824 disposed on the second connecting block 823 that can be embedded in the connecting sleeve 822, and a limiting member 825 disposed between the connecting rod 824 and the connecting sleeve 822. Specifically, the limiting member 825 includes a plurality of limiting holes 826 spaced apart on the connecting sleeve 822 and a limiting block 827 disposed on the connecting rod 824 that can be embedded in the corresponding limiting holes 826.
