An adjustable full-layer fertilization device

Abstract

The invention relates to a key part of a combined seed and fertilizer drill of agricultural machineries. In order to guarantee height stability of a first fertilizer layer for subsoil and whole layer fertilization as well as adjust fertilizing amounts of soil layers at different depths, the invention provides an adjustable whole layer fertilization device; the device comprises a shovel shaft, shovel edges, a shovel point, a fertilizer guiding groove, fertilizing holes, a first layer fertilizing hole, a seed fertilizer fertilizing pipe, a fertilizer guiding pipe, fertilizer guiding sheets, and a fertilizing adjustment sheet. Several fertilizer guiding sheets which extend outwardly are installed at fertilizing holes of different heights which are behind the fertilizer guiding groove, the upper side of the first layer fertilizing hole is provided the seed fertilizer fertilizing pipe, and the upper side of a back wall of the fertilizer guiding groove is provided with the movable fertilizing adjustment sheet; a fertilizer outlet of the seed fertilizer fertilizing pipe slants to one side of the shovel shaft; the lower end of the movable fertilizing adjustment sheet upwarps; the fertilizer guiding pipe is below the first layer fertilizing hole; the front ends of the fertilizer guiding sheets are in the fertilizer guiding groove, the rear ends of the fertilizer guiding sheets extend to the outside of the fertilizer guiding groove, and the widths of the fertilizer guiding sheets are more than the width of the fertilizer guiding groove; rear ends of adjacent fertilizer guiding sheets of different depths gradually become narrower from up to bottom, and the fertilizer guiding sheets gradually become short from up to bottom.

Description

technical field [0001] The invention relates to key components of a fertilizing and seeding machine in agricultural machinery. Background technique [0002] With the development of agricultural production and the popularization and application of advanced agricultural cultivation techniques, the sowing and fertilization techniques of corn are also constantly being perfected and improved. Corn is a crop that needs more fertilizer and absorbs fertilizer intensively. Correct and reasonable topdressing fertilizer is very important to promote roots, strengthen stalks, increase ears, and increase per unit yield. Tests have shown that the superficial root system has a strong ability to absorb fertilizer in the early stage of corn growth; the deep root system has a strong effect in the late stage of growth. Therefore, in order to meet the fertilizer requirements of corn growth and development, it is necessary to vigorously promote and popularize the mechanical subsoiling and deep ...

AI Technical Summary

Problems solved by technology

However, due to the different speeds of returning to the soil after deep loosening due to different soil properties, the depth of the first layer of fertilizer cannot be guaranteed during the deep fertilization process. In addition, different regions have different requirements for the amount of chemical fertilizer applied, so an adjustable full-layer fertilization is designed. The device is of great significance to ensure the depth of the first layer of fertilization, adjust the amount of fertilizer at different depths, and improve labor efficiency and crop yield.
