Quantitative topdressing mechanism in corn intertillage period

Abstract

The invention discloses a quantitative fertilization mechanism in a corn intertillage period, and aims to solve the problems that manual and mechanical topdressing operation in the intertillage period of corn planting is not easy to perform in a field, the working space is small, crops are easy to damage, fertilizer is wasted, the topdressing effect cannot be achieved and the like. The quantitative fertilization mechanism is characterized in that when the quantitative fertilization mechanism performs field operation, a furrow opener on the front side of the mechanism divides soil to two sides, and after quantitative topdressing operation is completed, a soil covering device on the rear side of a charging barrel covers the surface of the fertilizer with the soil, so that the fertilizer is in full contact with the soil, and the quantitative topdressing effect is achieved; the mechanism does not have working dead angles, so that fertilizer accumulation is avoided; no topdressing is omitted; the furrow opener, the charging barrel and the soil covering device work separately, so that the interference phenomenon does not exist; the arc-shaped design of a rotating plate ensures that the fertilizer in a fertilizer limiting sleeve completely falls into furrows; and bolts enable a fertilizer baffle and the rotating plate to coaxially move, so that the movement track of the fertilizer in the charging barrel is ensured, the smooth operation of quantitative topdressing is ensured, the manual topdressing cost can be reduced, and the topdressing effect in the corn intertillage period can be ensured.

Description

technical field [0001] The invention relates to a quantitative fertilization mechanism for corn plants during the inter-cultivation period, which is especially suitable for adding fertilizer in the case of high stalks in the mid-growth period of corn. Background technique [0002] At present, most of the existing corn topdressing methods are artificial topdressing operations in the early growth stage of corn and when the corn stalk is relatively short. This topdressing method can only supplement the nutrient needs of corn stalks in the early growth stage. In the middle stage of corn growth, the stalks gradually grow taller, and it is difficult to perform topdressing operations manually. Satisfying the needs of corn growth leads to the lack of corn nutrients, slow growth and development, and affects yield. Contents of the invention [0003] In order to overcome the disadvantages of existing corn topdressing equipment, the invention provides a quantitative topdressing mecha...

Problems solved by technology

[0002] At present, the existing corn topdressing methods are mostly artificial topdressing operations in the early growth stage of corn and when the corn stalk is short.

This topdressing method can only supplement the nutrient needs of corn stalks in the early growth stage. In the middle stage of corn growth, the stalks gradually grow taller, and it is difficult to perform topdressing operations manually. Meet the needs of corn growth, resulting in the lack of corn nutrients, slow growth and development, affecting yield
