Study on Seeding Weight Detection Device of Rice Seedling Production Line

At present, it is mainly by manual labor to measure and adjust the sowing amount during the working of rice seedling raising production line. By manual monitoring method, the labor intensity of workers is high, and the workers cannot adjust the sowing amount timely. So the error rate of the sowing amount is high, and this restricts the production efficiency of industrialized seedling production line In order to solve this problem, an automatic weighing device for the sowing amount in seedling tray on rice seedling production line is developed. The weighing device combined dynamic transport of trays and static weighing method. An experiment was carried out with the weighing device, and the results of the experiment shows that the weight accuracy of the device is over 99.79% at low seeding rate (40g~80g/ tray); The weighing accuracy is over 99.92% at large sowing rate (100g-120g/tray). The accuracy of the detection can meet the requirements of rice seedling production lines, and the detection device can effectively improve the automation and production efficiency of rice seedling production lines.
