Embodiment Construction
[0007] The embodiment will be described in detail in conjunction with the accompanying drawings. In the present invention, a row of pipe racks 3 is evenly distributed horizontally at the bottom of a screen box 1, and a plurality of pipe racks 3 are installed on the pipe beam from front to back parallel to the side wall of the screen box. Step-shaped tooth-shaped support ribs 1, on each tooth-shaped support ribs are respectively equipped with multi-layer stepped lower sieve bars 2. When the material passes through the sieve surface composed of sieve bars, it not only shortens the movement distance at the same height and reduces the probability of material jamming, but also uses the height difference to make the material have an uninterrupted motion acceleration, increase the flow rate of the material, and prevent the material from being stuck. Stuck to achieve fast and efficient completion of the material classification process.

The invention discloses a large-granularity material sieve plate structure. The large-granularity material sieve plate structure comprises a sieve box. A row of pipe beams are transversely evenly distributed at the bottom in the sieve box. A plurality of stepped tooth-shaped supporting ribs are evenly distributed on the pipe beams from front to back and parallel to the side wall of the sieve box, the front of the supporting ribs is high, and the back of the supporting ribs is low. Multiple layers of sieve plate strips are installed on the tooth-shaped supporting ribs respectively and decreased in a stepped mode. The sieve plate structure has wear resistance and impact resistance, materials can be effectively prevented from getting stuck, and sieving efficiency is improved.
Description
Technical field: [0001] The invention relates to sieving, in particular to a sieve plate structure suitable for sieving large-grained materials. Background technique: [0002] Most of the current sieve plate structures are only suitable for screening materials with small particle size and low impact force. If you want to screen materials with large particle size, you must do buffer treatment. After the buffer zone is set at the feed end, the length of the screen box and the manufacturing cost will be greatly increased, and there is still a certain phenomenon of material jam, which will affect the screening efficiency and quality. Invention content: [0003] The purpose of the present invention is to provide a sieve plate structure which has strong impact resistance, is not easy to jam, and is especially suitable for screening large-grained materials. [0004] The technical solution of the present invention is accomplished in the following manner, a sieve plate structu...
