Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1 to 4, the polysilicon crushing and screening machine of the present invention comprises a frame 4, a crushing device and a screening device. The frame 4 is provided with the three-layer, and crushing box 2 installs in frame 4 upper strata, and fine screen mechanism, coarse screening mechanism and coarse fodder collecting hopper 7 install in frame 4 middle level, and the collection dolly 10 that corresponds below fine screen mechanism, coarse screening mechanism and coarse fodder collecting hopper 7 is installed in frame 4 lower floor. The crushing device comprises a crushing box body 2 and a crushing collecting hopper 11. The upper end and the lower end of the crushing box body 2 are both open, the opening at the upper end of the crushing box body 2 is connected with a protective door plate 1 in a sliding mode, a handle is arranged on the protective door plate 1, and the protective door plate 1 is a transparent plate. The crushing box body 2 is rotatably connected with two crushing rollers 3 which rotate in opposite directions, and the opening at the lower end of the crushing box body 2 is connected with a crushing aggregate bin 11. Fine screen mechanism, coarse screen mechanism and coarse fodder collecting hopper 7 are installed in proper order on frame 4 along the pay-off direction, coarse screen board 6 and fine sieve 5 are connected with the coplanar, coarse screen board 6 and fine sieve 5 slope setting in frame 4, fine sieve 5 is just to the discharge gate direction of broken collecting hopper 11, fine sieve 5 below is connected with first collecting hopper 14, coarse screen board below is connected with second collecting hopper 12, first collecting hopper 14, the discharge gate of second collecting hopper 12 and coarse fodder collecting hopper 7 is just to collecting dolly 10 setting.
