Automatic fertilizing device for farmland soil improvement

Abstract

The invention relates to the technical field of agricultural machinery, in particular to an automatic fertilizing device for farmland soil improvement. The automatic fertilizing device for farmland soil improvement comprises a mounting plate, a connecting structure through which an automatic fertilizing device is connected with an external driving machine, a rotary tillage mechanism connected with the mounting plate and used for loosening soil, a fertilizer storage mechanism connected with the mounting plate, a discharging mechanism connected with the mounting plate, and used for unidirectionally and uniformly discharging fertilizers in the fertilizer storage mechanism to a fertilizing pipe mechanism, the fertilizing pipe mechanism used for spreading the fertilizers, and an air gun mechanism connected with the mounting plate, wherein an air outlet of the air gun mechanism is communicated with the fertilizing pipe mechanism, and compressed air is regularly or controllably introduced into the fertilizing pipe mechanism through the air gun mechanism. The automatic fertilizing device for farmland soil improvement provided by the invention has the advantages of high fertilization efficiency, uniform fertilization and good fertilization effect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic fertilizing device for farmland soil improvement. Background technique [0002] Fertilization refers to the agricultural technical measures of applying fertilizers to the soil or spraying them on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, fertilize soil and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The main basis for fertilization is the level of soil fertility, crop type, target yield, climate environment and fertilizer characteristics, so as to select the appropriate fertilizer and estimate the required amount of fertilizer.

AI Technical Summary

Problems solved by technology

[0003] At present, in order to avoid unnecessary volatilization of fertilizers on the surface of the soil when fertilizing, generally, fertilizers are directly sent to the inside of the soil. At present, the automatic fertilization device that can send fertilizers directly to the inside of the soil is used as fertilizer When entering the soil, the fertilizer generally falls by its own gravity, so that when the fertilizer enters the soil, the landing point is concentrated and the diffusion range is small, which affects the efficiency of fertilization. At the same time, the fertilizer is easy to accumulate, making the soil fertilization uneven , thereby affecting the effect of soil fertilization
