Corn-soybean strip-shaped compound planting no-tillage fertilization precision seeder

Abstract

The invention discloses a corn-soybean strip-shaped compound planting no-tillage fertilization precision seeder and belongs to the technical field of farm machines. The machine includes a suspension machine frame, a rotary tillage system, a power transmission system, a fertilization and ditching system and a sowing and soil covering system. Through an installation mode that reverse-rotation rotarytillage and the inclined and forward arrangement of a drive land wheel is combined, blades thus can cut stubbles forward, the stubble cleaning and soil breaking effects are ensured, the drive wheel thus can always walk on the ground, the occurrence of seedling missing and ridge breaking is avoided, and the seeder has the advantages of being simple in structure, precise in sowing, uniform in quality and the like, Under various kinds of parameters, the plant distance is adjusted and changed, and the minimum plant distance can be adjusted to 6 cm, the application range is wider, and smooth implementation of a high-yield close-planting mode is ensured. The seeder has high adaptability to crops, and is suitable for simultaneous sowing operation of corn, soybeans and other seeds with the shapesimilar to the shape of core or soybeans.

Description

technical field [0001] The invention belongs to the technical field of farmland machines and tools, and in particular relates to a no-tillage and fertilizing precision seeder for corn-soybean strip composite planting. Background technique [0002] The traditional no-tillage fertilization seeder uses the rotary tiller to rotate the ground backwards, and chooses the installation method of driving the ground wheel to be tilted and rearward in the power transmission. The problem of seedlings, the poor cutting effect of the rotary tiller may also easily lead to problems such as entanglement of the knife shaft and bulldozing at the end, which seriously affects the emergence of seedlings. Intermittent stoppages lead to the lack of seedlings, which affects the quality of sowing. At the same time, the adjustment range of the row spacing and plant spacing is limited, which cannot meet the requirements of the close planting mode for the sowing spacing, which affects the final crop yie...

AI Technical Summary

Problems solved by technology

[0004] In most of the current patents on no-tillage fertilization seeders, the driving ground wheels are all installed backwards, such as a stubble removal rotary tillage multi-layer fertilization seeder disclosed in Chinese patent 201210127847.7, and a kind of corn- Although the seeder for soybean intercropping can realize power transmission, it will cause the bouncing of the driving ground wheel due to the uneven terrain, and intermittent shutdown will occur, which will affect the seeding of the seed metering device and cause problems such as lack of seedlings and broken ridges.

At the same time, the row spacing and row spacing adjustment range of sowing monomers are limited, such as a portable mini-planter disclosed in Chinese patent 201410016671.7, and a corn and soybean seeder disclosed in Chinese patent 201220240901.4. -10,000 plants / mu single-grain precision sowing density scale, so it is difficult to meet the planting requirements of crop dense planting in hilly areas, affecting the final yield
