Design and Testing of a Self-Propelled Dandelion Seed Harvester

At present, there are few harvesters for dandelion (Taraxacum mongolicum) seeds, which limits the large-area planting of dandelion. Furthermore, manual harvesting is characterized by huge labor intensity, low efficiency, and high costs. Combining material characteristics plants seeds with agronomic requirements a self-propelled seed harvester was designed. The mainly composed collection devices, separation transmission rack. It can facilitate from plants, transportation, seed–pappus in one operation. processes were studied to ascertain main factors that affect rate. Then, devices designed, their parameters analyzed. Taking forward speed, wind velocity blowers, rate rotation drum as test evaluation index, quadratic regression orthogonal rotating field tests performed. In this way, optimal combination operation determined: when speed 0.8 m·s−1, air blowers 1.63 419 rpm. Field results showed favorable effect achieved after harvester, only small amounts remained unharvested. Under parameter combination, reached 89.1%, could meet practical seeds. satisfy design requirement.
