Design and Experiment of Missing Seeding Detection and Automatic Reseeding System of Potato Planter
摘要
Abstract
Aiming at the serious problem of seed omission in the high-speed operation of potato planters,a seed omission detection and automatic reseeding device was designed based on a spoon belt type seed metering device and with a PLC as the control core.The device used a group of photoelectric sensors to detect the seed omission of the spoon belt type seed metering device and the reseeding device respectively,achieving precise positioning of the seed spoon omission position.An automatic reseeding device with a reseeding device and a double electromagnetic iron push rod as the core was designed to achieve continuous and precise reseeding at the omission position.At the same time,the principle of accelerated reseeding was adopted to realize the self-reseeding of the reseeding device,avoiding the influence of unsuccessful reseeding on the reseeding effect of the spoon belt type seed metering device.Control programs were written according to the requirements of seed omission detection and reseeding control,and a human-machine interface was designed to achieve automatic reseeding.The detection effect of seed omission and the success rate of reseeding were tested on a test bench with the seed metering belt speed ranging from 0.24 m/s to 0.64 m/s.The results showed that the detection accuracy of seed omission was 100％,the original seed omission rate was from 6.08％to 13.64％,and the seed omission rate after reseeding was from 0.72％to 1.96％,with an average reseeding success rate of 87.16％.The test results indicated that the seed omission detection and automatic reseeding device had good working performance and stable reseeding effect for continuous seed omission of the seed spoon,meeting the seeding operation requirements of potato planters under high-speed operation.关键词
