Description

Intertillage subsoiling layered fertilizer applicator aiming at corn straw row returning mode

Technical Field

The utility model belongs to the technical field of whole mechanization of maize protective farming, specifically speaking is a soil farming machinery that carries out intertillage subsoiling layering fertilization at maize seedling stage.

Background

In recent years, the protective cultivation and planting area of corn in China is continuously increased, and the problem of difficulty in protective cultivation and seeding of corn is solved by the adoption of the corn straw row returning mode, so that the corn straw row returning mode is accepted by more and more farmers, but the returned corn straw also has certain influence on deep scarification and fertilization operation in the seedling stage of the corn. During intertillage subsoiling fertilization operation, the operating position of the subsoiler is just on the corn straw belt after returning, due to the blocking effect of the straw after returning, the straw is wound on the subsoiler when the subsoiler is operated, and the phenomenon of dragging and piling the corn straw is generated along with the advancing of the subsoiler. Meanwhile, due to the action of the subsoiler, the corn straws which are originally returned to the row move to the two sides of the subsoiler, and the corn straws are dispersed in a small range, so that the intention of the straw returning mode is violated. In order to solve the above-mentioned difficult problem, specially proposed the utility model provides an intertillage subsoiling layering fertilizer distributor can accomplish to carry out subsoiling layering fertilization under the maize straw mode of returning to the throne and can not appear the subsoiling shovel winding straw, the straw drags the circumstances of piling and returning to the straw dispersion after the line, has guaranteed the maize straw mode of returning to the throne smoothly to carry out, thereby make maize can steady production, high yield, maize straw is total still field. The utility model discloses a complete machines of straw mode of returning to the throne appear perfect, must further promote the rapid development of protective farming.
