Design of scallop seedling specification recognition and counting device

In this study, considering the problems of large labor, high labor intensity, high breakage rate, and large statistical error in the marine specification identification and counting statistics of bottom-sown scallop seedlings, a device for identifying and counting the scallop seedlings was designed; the device consisted of three parts: primary sorting mechanism, differential queuing conveyor and specification identification system, and counting statistics system. To determine the factors affecting the device accuracy for identifying and counting shellfish seedlings, five factors and four levels were established for orthogonal test analysis and verification, and the best process parameters of the device for shellfish seedling classification were determined. The size of the feeding port was 40 mm×25 mm, the rotating speed of the conveyor belt motor was 125 r·min^-1, the radian of the attitude-adjusting mechanism was 20, the distance between the attitude-adjusting mechanism and the end of the conveyor belt was 4 mm, and the interval for the shellfish seedling identification was 17 ms and 25 ms. In the verification test, the average recognition and counting accuracy was 94.4%; thus, the device has good stability and can therefore provide technical support for the integration of scallop seedling acquisition and the bottom sowing at sea.
