“…The increase in particle size not only improves the fluidity of seeds in terms of physical properties, but also facilitates mechanized and precise seeding, thereby achieving the purpose of improving seeding efficiency and reducing seed waste. Therefore, how to use high-quality coating technology to achieve the diversity and functional specificity of coated seeds is an urgent and realistic demand Bai, 2020). Seed coating technology in China started in the 1980s, which is relatively late compared to some countries in the West.…”

In view of the problems of long coating time, complicated manual operation, high multi-seed rate of coated seeds, low qualified rate, and low degree of automation of control equipment in traditional rotary coating machine, a new type of rotary coating machine was designed while using LabVIEW with a complete electric control system, which can effectively improve the speed and quality of coating. The system uses single-chip microcomputer as the lower computer, LabVIEW as the upper computer, and uses programming electronic control technology to set seed coating parameters in advance, precisely control each part and achieve precise supply. Batch supply of powder and liquid greatly improves the automation and intelligence of the operating system, improves the coating efficiency, reduces the multi-seed rate and the seedless rate, and increases the coating pass rate. In order to improve the coating quality and the supply accuracy of the coating machine, the error analysis and calibration test of the seed supply system, powder supply system and liquid supply system were carried out. After the test verification, the supply error was controlled within 2% to meet the demand for precise supply. The test results show that the pass rate of the seeds coated by the new rotary coating machine is increased by 15% to 20% compared with the seeds coated by the traditional manual coating.

While studying the coating theory, due to the lack of the support of the rapid identification and detection device for coated red clover seeds, for a long time, we have mainly relied on manual visual inspection to sort qualified coated seeds, only relying on human eyes to identify the cause of low efficiency, high wrong classification rate and high labor intensity. In order to identify the coated red clover seeds quickly and efficiently, a set of intelligent identification and detection system for coated red clover seeds was designed. First of all, by building a machine vision shooting platform to ensure that the light source and other shooting conditions are consistent, the images are transmitted to Vision Assistant 2018 for image processing. Secondly, two image processing algorithms are designed to process qualified coated seeds and damaged coated seeds respectively. Finally, an identification and detection algorithm is proposed, which uses LabVIEW2018 as the host computer to identify the qualified number and the damaged number. Taking red clover seeds as the test object, the test results show that the entire system takes about 1 second to collect and process a single image; the recognition accuracy of qualified coated seeds and damaged coated seeds is above 96% and 85%. The identification and detection system realizes the nondestructive detection of coated seeds, and provides theoretical basis and technical support for the later research on the optimal seed coating process, deepening the theoretical research of the coating machine and improving the degree of automation.
