Design and Experiment of the Pneumatic Plate-Type Vegetable Seeder

Abstract:

Structure plan of a new type of pneumatic plate-type vegetable seeder was put forward, and virtual prototype of the seeder was established in the paper. By kinematics simulation and analysis, L-shape arm length and minimum distance between metering device and cell plug tray were optimized. The machine control system and air pressure switch system were designed in detail. Results of orthogonal test show that, the main influence factor for single-seed rate and empty-seed rate is sowing efficiency, the second is diameter of suction hole, next is relative pressure, the minimum is interaction between those factors. The main influence factor for multi-seed rate is diameter of suction hole, the second is relative pressure, next is interaction between factors, the minimum is sowing efficiency. The best seeding effects can be achieved under the condition of 0.9 mm suction hole diameter, -4.5 kPa relative pressure, and 200-tray per hour sowing efficiency. The single-seed rate can be up to 93.59%, the empty-seed rate is 1.25%，and the multi-seed rate is 5.16%。
