<p>PURPOSE: An impact resistance and abrasion resistance strainer is provided not to be easily deformed or damaged even if the material such heavy aggregate is classified by a particle size. CONSTITUTION: An impact resistance and abrasion resistance strainer continuously has a function line in predetermined interval comprised by connectively attaching a fixing piece of a plate shape in both sides of elastic material. The impact resistance and abrasion resistance strainer has iron line(101) continuously arranged in predetermined interval to form a right angle with a function line(110) in the lower part and is welded with the function line. In lower part of the fixing plate, a curve-shaped support is formed. A fixing piece is formed into one by a U shape. The elastic material is molded with one material among a synthetic rubber, a synthetic resin and an abrasion resistance special steel.</p> |
