Design and analysis of garlic underseeding detection and replanting system

In view of the development status of missing seed detection and replanting technology of agricultural machinery in China, the structure and working principle of missing seed detection and replanting technology of various types of agricultural machinery are expounded, and on this basis, a new photoelectric sensor, diffuse reflection laser sensor, is used to collect the seed collection process in the field of garlic planting, and the missing garlic seed is judged by the pulse width output by the sensor. A garlic reseeding device with electromagnetic clutch and rotary spoon replanting device as the core was designed, and the principle of reseeding was discussed. With STM32 microcontroller as the core, diffuse reflection laser sensor and electromagnetic clutch as the core, a missed seeding detection and replanting system for the garlic planting industry was developed.
