AI Technical Summary

Technical Problem

Existing fertilization equipment lacks a point-guided mechanism during fertilization, resulting in uncontrollable fertilizer application and the formation of localized high-concentration fertilizer solution zones at the bottom of the pit, which can lead to root burn in seedlings.

Method used

A fertilizer application device was designed, comprising a mobile vehicle body, a storage bin, a conveying cylinder, a spiral auger, fixed and movable discharge pipes, and a linkage mechanism. The device achieves precise and targeted fertilizer application by using a swing arm and linkage mechanism, avoiding the bottom of the pit, and prevents the fertilizer from being washed to the bottom of the pit by using a push plate to cover the soil.

Benefits of technology

This method enables precise and targeted application of fertilizer, avoids the formation of high-concentration fertilizer solution zones at the bottom of the pit, protects the seedling roots, and ensures uniform fertilization and continuous fertilization.

Abstract

The application discloses a kind of fertilization device of automatic adjustment fertilization amount, it is related to agricultural machinery technical field, including mobile car body, storage bin, conveying cylinder, conveying shaft, spiral auger, intercommunication bin, fixed blanking pipe, baffle assembly, movable blanking pipe, lifting drive cylinder, fertilization pipe;Swing arm is rotatably connected on movable blanking pipe, swing arm and fertilization pipe between being equipped with linkage mechanism, swing arm is pressed swing and is moved horizontally by linkage mechanism to deviate the pit bottom of planting pit when driving fertilization pipe.This application, by setting swing arm and linkage mechanism, in the process that fertilization pipe is moved down with movable blanking pipe, swing arm (front side) touches the sidewall of planting pit and occurs swing, mechanical linkage forces fertilization pipe to horizontally deviate rear sidewall.This makes fertilizer accurately avoid pit bottom, and is positioned in planting pit on the sidewall, fundamentally eliminates the problem of " root burning " caused by high concentration fertilizer solution area that dissolving of chemical fertilizer in pit bottom water area.
