AI Technical Summary
When collecting pollen, existing rice pollination devices knock on the rice parent plant through elastic rods, which may cause branches and trunks to break and affect subsequent pollen generation.
A hybrid rice pollination device was designed, using slide rails and hydraulic cylinders to drive the rollers. The outer surface of the rollers was covered with felt pads. The pollen was stuck and collected through contact with the rice plants through the rollers. The movement trajectory was straight up and down to avoid external force hitting.
It effectively avoids damage to the branches and trunks of the rice parent plant, ensures the complete collection and subsequent generation of pollen, and achieves uniform pollination without damaging the rice plant.
