The utility model discloses a material prescreening device can reach fine sifting out metal debris wherein, can play the effect of primary breakage again to the material, improves the efficiency of subsequent handling. When the utility model is used, firstly, the material is put on the transmission belt, in the transmission process, the rubber hammer above the material is moved up and down to crush the material, the material agglomerated by big blocks is crushed, the situation that the wrapped metal or other sundries are difficult to be screened out can be avoided, the material falls into the screening cavity of the screening box after coarse crushing, firstly falls onto the coarse screen, the coarse screen is made of magnetic material and has magnetism, therefore, the metal sundries can be adsorbed on the coarse screen, other materials pass through the coarse screen and continue to fall onto the first screen, wherein the material conforming to the mesh size of the first screen continues to fall, some larger-sized materials left on the first screen move along the inclined first screen towards the lower side, the materials enter the reprocessing cavity after passing through the through hole of the clapboard, the roller above the first screen rolls the material entering the reprocessing cavity in the rotation process, make the further fragmentation of bigger size material can pass first screen cloth and fall on the second screen cloth, the material that drops on the second screen cloth repeats above-mentioned step, the material that accords with follow-up broken size demand directly passes the second screen cloth, and the great motion of size is to retreatment chamber along the second screen cloth surface, repeat above-mentioned operation, collect the material of screening bottom of the case portion at last and carry out subsequent handling, and wherein remaining material above the screen cloth in retreatment intracavity then can retrieve and reprocess, the adsorbed metal on the coarse screen cloth also can be collected and be used as his way. The operation principles of the roller rotating around its axis, driving the rubber hammer to move up and down, and the transmission belt are all prior art, and therefore, are not described in detail herein.

The first screen and the second screen are inclined at an angle of 30-45 deg. to enable the material to move along the screens at a relatively modest speed.

The outer wall of the roller is covered with rubber convex thorns, so that the blocky agglomerated materials can be punctured and cut, and meanwhile, the roller can be prevented from being damaged when encountering hard solid objects.

The distance between the top edge of the perforation and the surface of the first screen or the surface of the second screen is 8-10cm, so that materials with the size exceeding the size cannot pass through the through hole, and the phenomenon that the roller is overloaded due to the overlarge size is avoided; if the materials blocked by the through holes and cannot pass through the through holes are too much in the above conditions, the materials can be cleaned manually, and the blockage is prevented from influencing subsequent operation.

The first screen and the second screen are made of magnetic materials, so that small metal impurities in the materials can be further removed, and the safety of the subsequent crushing process is improved.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the material primary screening device for anaerobic dry fermentation can well screen out metal impurities in the material, can also play a role in primary crushing of the material, and improves the efficiency of subsequent processes;

2. the utility model discloses a material primary screen device for anaerobic dry fermentation, the inclination angle of first screen cloth and second screen cloth is 30-45, can make the material move along the screen cloth with relative suitable speed;

3. the utility model is used for dry fermentation's material prescreening device of anaerobism, the outer wall of cylinder coats and is stamped the protruding thorn of rubber, can prick the material of cubic reunion and cut apart, can avoid causing the damage to self when meetting the hard article of solid simultaneously.
