Simultaneously, in graded operation, material is motion on compass screen surface, friction constantly, causes compass screen surface constantly to wear and tear.The tradition sieve plate is owing to adopt carbon steel and manganese steel to be made mostly, though have certain wearability, service life is unsatisfactory.Because service life is shorter, the user in use needs constantly to change sieve plate.

Be exactly that traditional sieve plate is integral production in addition,, just must change the monoblock sieve plate if concentrated wear appears in compass screen surface.And the sieve plate area is bigger, and it is extremely inconvenient to change sieve plate, returns the user and has caused unnecessary waste, increases use cost.

Summary of the invention

To be solved by this invention is exactly that existing vibrating screen classifier sieve plate adopts bolt to connect; Overhaul of the equipments and the operation of changing consumable accessory are caused very big inconvenience; Sieve plate is an integral production simultaneously; Changing inconvenience also increases the problem of use cost, and a kind of easy to loading and unloading, long service life, vibrating screen classifier sieve plate that screening effect is good are provided.

Vibrating screen classifier sieve plate of the present invention; Comprise sieve plate and sieve plate card article, sieve plate is fixed on the sieve plate card article, it is characterized in that the sieve plate card article is the cylinder that the cross section is the U type; Two tops of U type are designed with circular convexity respectively, and protruding diameter is greater than the thickness of sieve plate card article; The place, two ends at the sieve plate back side is provided with arc-shaped slot, and the arc-shaped slot diameter is not more than protruding diameter, during assembling, raps sieve plate with rubber hammer, makes convexity snap in the arc-shaped slot, and draw-in groove is connected with the interference of sieve plate card article.

Described sieve plate dual-side along on be cast with the semicircle boss of symmetry, the moving forward and backward of sieve plate when being convenient to assemble, simultaneously boss can also be not at the material diversion of sieve aperture part to the compass screen surface that sieve aperture is arranged, material is fully passed through sieves.

Sieve aperture on the described sieve plate is tapered, and the sieve diameter in sieve plate front is convenient to the sieve aperture mediation less than the sieve diameter at its back side, avoids stopping up, and has improved screening efficiency.

Described sieve plate card article is processed with mild steel is cold rolling; Sieve plate uses polyurethane to process as material.

This sieve plate adopts the fabricated structure of small size, multimode, during the Where topical serious wear, can only change local sieve plate, effectively reduces the replacement cost of monoblock sieve plate.

Vibrating screen classifier sieve plate of the present invention, simple in structure, reasonable in design, easy accessibility, the sieve plate card article is connected with the sieve plate interference, connects more fasteningly, and the convexity of toroidal is adopted at sieve plate card article two ends, and angle limits was little when sieve plate was installed, and was easier to the loading and unloading of sieve plate; During mounted sieve, use rubber hammer to knock in and get final product, improved efficiency of assembling; Simultaneously, sieve plate adopts the fabricated structure of small size, multimode, during the Where topical serious wear, can only change local sieve plate, effectively reduces the replacement cost of monoblock sieve plate; During replacing, with the edge joint position of two sieve plates of homalocephalus bottle opener insertion that can knock, the sieve plate that needs are changed levers up gently, and both hands are firmly pulled sieve plate obliquely, just can the monoblock sieve plate be broken away from the sieve plate card article.
