Other claims from this paper (13)
- Intervention effect The shaped-hole seed meter had significantly higher planting precision than the meter without a shaped hole.
- Intervention effect Seed disturbance structure II gave better planting precision than the other disturbance structures.
- Observation With seed disturbance structure II at 60 rpm and 2.0 kPa, the feed index quality was 90%.
- Observation With seed disturbance structure II at 60 rpm and 2.4 kPa, the feed index quality was 91.11%.
- Observation With seed disturbance structure II at 60 rpm and 2.8 kPa, the feed index quality was 89.17%.
- Observation With seed disturbance structure II at 60 rpm and 2.0 kPa, the miss index was 2.96%.
- Observation With seed disturbance structure II at 60 rpm and 2.4 kPa, the miss index was 1.94%.
- Observation With seed disturbance structure II at 60 rpm and 2.8 kPa, the miss index was 1.57%.
- Intervention effect At high rotational speeds, seed disturbance gave better rice bunch planting precision than no disturbance structure.
- Intervention effect In simulation, the seed velocity and total force magnitude were lower in the meter without disturbance structures than with the disturbed structure.
- Observation In simulation, seed disturbance breaks up the stacked state of seeds.
- Mechanism Seed disturbance improves seed mobility, which enhances the precision of bunch planting.
- Mechanism The shaped hole holds the seed in a stable suction posture, which helps increase the seed-filling rate.
