The utility model discloses an
egg product detecting and knocking grader which comprises a grading conveyor and a conveying chain arranged on the grading conveyor and used for conveying egg products, a
machine box located above the conveying chain is fixedly installed on the grading conveyor, a fixing frame is fixedly installed in the
machine box, an ultrasonic
transducer is installed below the fixing frame, and the ultrasonic
transducer is connected with the grading conveyor. The bottom of the ultrasonic
transducer is fixedly connected with a straight spring, the upper end of the knocking rod is connected with the lower end of the straight spring, and the lower end of the knocking rod is provided with a hammer. The
vibration amplitude generated by the ultrasonic transducer is extremely small, and the straight spring has elasticity and
scalability, so that the hammer head is easy to rebound when knocking an
egg product, the egg shell cannot be broken due to direct hard
impact on the
egg product, and the egg shell breaking device is suitable for the egg products with different sizes and
eggshell thicknesses; the problem that eggshells are prone to being cracked when the egg sizes are too large and the eggshells are small in thickness due to the fact that a traditional egg product crack
sound wave detection egg knocking grading
machine uses a hammer head for direct physical
impact to knock eggs for grading is solved.
