AI Technical Summary
Existing seed metering devices have problems such as the number of seeding paths not being adjustable or difficult to adjust, easy to miss or repeat seeds, complex structure, low space utilization, poor adaptability, and high difficulty in disassembly and assembly.
Two independently driven inner and outer seeding mechanisms were designed. The inner seeding mechanism is used to control the number of seeding paths and the number of seeds per hole, while the outer seeding mechanism integrates seed storage function. Through the cooperation of the inner and outer seeding mechanisms, multi-path synchronous seeding can be achieved, and the number of seeding paths can be flexibly adjusted to adapt to different seeds.
The mechanical structure has been simplified, the space utilization rate and the adaptability of agricultural machinery to terrain have been improved, the maintenance and debugging costs have been reduced, and high-precision multi-path sowing and seed compatibility have been achieved, with a seeding accuracy rate of 98.5%.
