The utility model is realized by following measure, mainly is made up of screen box, compass screen surface, vibrator, transmission gear for electric motor, vibration damping support device and frame; Vibrator is installed on the screen box, and is connected with transmission gear for electric motor, it is characterized in that: described screen box is double-deck, and upper strata screen box and lower floor's screen box are installed on the frame of vibratory sieve by vibration damping support device respectively; Every layer of screen box all has independently vibrator.
The vibrator that is positioned at the upper strata screen box is that one of following three kinds of forms: a, vibrator are installed on the screen box, and the rotating shaft of vibrator is vertical with sieve box side plate, parallel with compass screen surface single shaft vibrator; B, vibrator are installed on the screen box, and the rotating shaft of vibrator is vertical with sieve box side plate, parallel with compass screen surface dual-axis vibration device; C, there are two identical vibrators of parameter to be installed in respectively on two side plates of screen box, the rotating shaft of two vibrators is parallel to each other and parallel with the side plate of screen box, the direction of rotation of two vibrator rotating shafts is identical or opposite, and the vibrating deflection that its plane, movement locus place and compass screen surface form is 5～65o.
The vibrator that is positioned at lower floor's screen box is that one of following three kinds of forms: a, vibrator are installed on the screen box, and the rotating shaft of vibrator is vertical with sieve box side plate, parallel with compass screen surface single shaft vibrator; B, vibrator are installed on the screen box, and the rotating shaft of vibrator is vertical with sieve box side plate, parallel with compass screen surface dual-axis vibration device; C, there are two identical vibrators of parameter to be installed in respectively on two side plates of screen box, the rotating shaft of two vibrators is parallel to each other and parallel with the side plate of screen box, the direction of rotation of two vibrator rotating shafts is identical or opposite, and the vibrating deflection that its plane, movement locus place and compass screen surface form is 5～65o.
Needs according to the stock grading screening can be respectively arranged with the multilayer compass screen surface on upper strata screen box and lower floor's screen box.
The beneficial effects of the utility model are; the above is positioned at the vibrator of upper and lower layer screen box; the single shaft vibrator that its three kinds of forms are respectively the circular motion tracks; the dual-axis vibration device of straight-line trajectory, and vibrator rotating shaft straight-line trajectory, circular motion track or the elliptical trajectory vibrator parallel with sieve box side plate.According to the heterogeneity of screening material, the movement locus of upper strata screen box and lower floor's screen box can be arranged in pairs or groups flexibly and be selected for use, makes the screening of material reach more satisfactory effect.Can satisfy the needs of multiple sieving technology, applicable to screening operation to various materials.
