The invention discloses a modularized linear vibrating screen. The modularized linear vibrating screen comprises a linear vibrating screen, the main improvement point is that at least two net racks in parallel butt joint are mounted on the inner periphery of a screen box through net supporting plates, modularized screen net fixing clamping grooves evenly distributed are formed in each net rack, and a screen net module is mounted in each clamping groove in a tight matched mode. Net pressing frames are mounted between the net racks and the inner wall of the screen box correspondingly. According to the modularized linear vibrating screen, a screen net is modularized, and the modularized linear vibrating screen has the advantages of being convenient to mount and repair, and capable of reducing repair cost and improving production efficiency.
