- Abstract
The air-suction seed metering device with automatic detection and reseeding function was designed. The device is mainly composed of metering disc, reseeding device, detection system, signal processing and control system, alarm device and power supply. Based on the photoelectric sensors, the seed metering device is detected. The timed reseeding function was realized through the detection and control system. The correlation performance tests were done by comprehensive weight score value method. The test results had shown that: under the operating conditions of 4kPa and 15r/min, the seed metering device has the best seeding effect; the qualification rate of the seed metering device with the reseeding device is 93.68%, the over-seeding rate is 3.91%, the miss-seeding rate is 2.38%; compare the installed reseeding device with the uninstalled reseeding device, the qualification rate of the seed metering device is increased by 2.34% and the miss-seeding rate is dropped by 3.09%, and the seeding quality of the seed metering device has been greatly improved.
