Mechanism analysis and experiment on the garlic directional control based on fluid solid coupling

How to realize the garlic seed direction control is the bottleneck problem of the garlic mechanical sowing in our country. Proposed garlic direction control method by using water based on the theory of fluid coupling, and its controlling mechanism is analyzed and tested. Through theory analysis, suitable water control rules to the body shape is on the tip of a coarse, left and right side symmetry, dorsal flap is lanceolate; Design test device, test the performances of the water control method, 98.5% rule body can erect in control the direction cup, satisfy the garlic planting requirements. This study provides reference for the design of the garlic direction controller.
