The utility model provides a kind of fry screening device for
aquaculture, it is related to
aquaculture technical field, including
organism, the inside of the
organism is provided with adjustable shaking screening mechanism, the side of the
organism is provided with humidification mechanism, the other side of the organism is equipped with PLC controller, the wiring end of the PLC controller is connected with device inner wire arrangement.This utility model in, by setting adjustable shaking screening mechanism, first
servo motor drives the rotation of one-way screw rod, moves the moving block under the restriction of first limit rod, further let rack drive gear and rotating rod rotate, realize that screen cylinder shakes, simultaneously, second
servo motor drives the rotation of two-way screw rod, can adjust the interval of two adjusting plate and
contact sensor, when moving block touches
contact sensor, will feedback
signal to PLC controller, control first
servo motor reverses, to this flexible adjustment screen cylinder shaking range, solved the problem that existing device cannot flexibly adjust shaking range.
