[0029] A movable plate 12 is rotatably connected to the top of the workbench 5 through a rotating shaft. Two groups of movable plates 12 are provided. A feed trough 13 is provided inside the middle position of the two groups of movable plates 12, connecting the outer frame 1 and the workbench 5, and a space is provided for the feed trough 13. The interior of the feed trough 13 is connected with the interior of the collecting box 4.
