The invention discloses a totally-enclosed environment-friendly net vibrating screen. The net vibrating screen comprises a vibration exciter and a bar screen plate, wherein the bar screen plate is fixed in a totally-enclosed screen box with a gradient of 20 to 40 degrees; strip vibration absorption plates are padded at the upper and lower ends and the middle part between the bottom of the bar screen plate and the screen box respectively, and baffle plates are fixed on two sides of each strip vibration absorption plate respectively; a vibration exciting device is arranged on the bottom outer wall of the bar screen plate; a circular vibration absorption block is arranged on the bottom outer wall of the bar screen plate at the upper side of the vibration exciting device; a horn-shaped torsional vibration absorption block is arranged on the screen box below the circular vibration absorption block; an air draft and dust removal port is formed at a discharge hole at the upper side of the screen box; and the screen box close to the vibration exciting device is provided with a service port. Because of light vibration weight, the net vibrating screen has the advantages of large material treatment amount, low energy consumption, effective prevention of dust pollution and realization of environmental protection.
