the inside of sieve frame still fixed mounting have a plurality of equidistance distribute be used for carrying on spacing vice strip to the main strip, vice strip perpendicular to main strip, and the junction of vice strip and main strip has seted up waist type hole, the activity of main strip runs through waist type hole, and a plurality of main strip forms grid form sieve material district with the combination of a plurality of vice strip.
Preferably, a plurality of the main strips are arranged in parallel, each main strip is of a cylindrical structure, and the diameter of each main strip is d.
Preferably, the size of the kidney-shaped hole is set to (d +1mm) × (d +2 mm).
Preferably, the diameter of the sleeve is d +1 mm.
Preferably, a plurality of the secondary strips are arranged in parallel, and each secondary strip is of a rectangular parallelepiped structure.
Preferably, the surface of each of the main strip and the auxiliary strip is coated with a wear-resistant layer.
Compared with the prior art, the utility model has the beneficial effects that:
according to the sieve plate, the plurality of rectangular auxiliary strips which are equidistantly and parallelly distributed are fixedly installed in the sieve plate frame in a vertical material flowing direction, the plurality of cylindrical main strips which are equidistantly and parallelly distributed are movably installed in the sieve plate frame along the material flowing direction through the sleeve, the plurality of main strips and the plurality of auxiliary strips are combined to form the grid-shaped sieve material area, waist-shaped holes are formed in the intersection positions of the auxiliary strips and the main strips, when materials which are slightly larger than the size of a sieve mesh pass through the sieve material area, thrust is generated on the main strips under the action of gravity, the main strips can slightly displace and rotate at the same time, the materials can be effectively prevented from being clamped in the sieve holes, accordingly, sieve plate blockage is reduced, the screening and classifying efficiency is improved, the energy consumption is further reduced, the practicability is improved, and the sieve plate is used for popularization and application.
