Description

Technical Field

[0001] This utility model relates to the field of seeding technology, and in particular to a precision seeder with adjustable wide and narrow rows for corn-soybean intercropping in hilly areas. Background Technology

[0002] In hilly areas, intercropping of corn and soybeans is an important model for improving land utilization and achieving stable grain production and increased soybean yield. However, the terrain is undulating and the soil conditions are complex, placing higher demands on the adaptability and precision of seeders. Traditional seeders mostly use a fixed row spacing design, which makes it difficult to simultaneously meet the different planting density requirements of corn and soybeans, and cannot adapt to the depth adjustment requirements of hilly slopes. Especially in wide-narrow row intercropping, corn requires wide rows to ensure ventilation and light penetration, while soybeans require narrow rows to achieve dense planting and increased yield. The existing equipment relies on manual disassembly and reassembly for row spacing adjustment, which is time-consuming and labor-intensive.

[0003] The most prominent drawback of existing seeders is their low efficiency in row spacing adjustment. Taking the common bolt-fixed row spacing adjustment scheme as an example, the operator needs to first remove multiple fastening bolts, then manually move the seeding unit to the target position based on experience, and finally retighten them. This process requires at least two people to operate, each adjustment takes 15-20 minutes, and is prone to row spacing deviations exceeding ±5cm due to visual estimation errors. In corn-soybean intercropping scenarios, frequent switching between wide and narrow row configurations is required, and the inefficient adjustment of traditional structures restricts operational efficiency, with the average daily effective operating area being less than 60% of that in conventional plains areas. In addition, repeated disassembly and reassembly of bolts can easily lead to stripped threads, further reducing equipment reliability. Therefore, a precision seeder with adjustable wide and narrow row spacing for corn-soybean intercropping areas in hilly areas is proposed to solve the above problems. Utility Model Content

[0028] Working Principle: When using an adjustable-row precision seeder for corn-soybean intercropping in hilly areas, the hydraulic cylinder 9, fixed inside the fixed block 10, pushes the connecting frame 8, causing the sliding block 7 to slide on the sliding plate 6. The connecting frame 8 slides on the connecting plate 14, driving the connecting plate 15. This causes the fixed block 16 to drive the connecting block 17, rotating the connecting plate 18. The connecting plate 18 rotates around the connecting rod 19, driving the connecting block 20 and the fixed block 21. This allows for rapid adjustment of the row width of the seeder to meet different needs. The connecting plate 14 is fixed by the connecting block 2 on the machine body 1, allowing the connecting frame 8 to rest on it. To achieve stable sliding, the seeds to be sown are placed into the funnel 3 and sown downwards through the discharge tank 4. The wheels 11 inside the machine body 2 5 slide, and the support block 25 supports the discharge tank 4. By gripping the connecting rod 24 and pulling it outwards, the connecting rod 3 29 inside the connecting block 4 23 is disengaged from the sliding block 22 and the support frame 12, allowing the sliding block 22 to adjust the height of the furrow opener 13. The limiting plate 2 30 is used to restrict the sliding of the limiting block 26. The limiting block 26 compresses the spring 27, and the limiting plate 1 28 is used to abut against the limiting block 26, so that the connecting rod 3 29 can automatically return to its original position. The height of the furrow opener 13 can be adjusted to meet different furrow depths.
