Chemical fertilizer applicator

Abstract

The invention belongs to the field of agricultural machinery, and particularly relates to a chemical fertilizer applicator which comprises a framework, a traction frame, rolling wheels, a fertilizer tank, a driving shaft, bearing blocks, a transmission shaft, a shifting shaft, shifting wheels, a first driving chain wheel, a first driven chain wheel, a second driving chain wheel, a second driven chain wheel, a first chain, a second chain, grooves, discharge pipes, furrowing plows and soil burying plates. The chemical fertilizer applicator has the advantages that the chemical fertilizer applicator is simple in structure and convenient to operate, is small, has diversified furrowing, fertilizer application and soil burying functions and is provided with the shifting wheels, and accordingly the fertilizer application rates can be accurately controlled; lands can be divided by the hollow furrowing plows with the adjustable depths and the adjustable widths, accordingly, fertilizers can flowinto underground environments along the furrowing plows, fertilizer application procedures can be completed, and the fertilizers can be buried by the rear hung soil burying plates; the lands and the root systems of original plants rarely can be destroyed by the chemical fertilizer applicator as compared with common fertilizer application modes, the chemical fertilizer applicator is provided with the conical fertilizer tank, accordingly, the fertilizers can automatically flow to the shifting wheels in hourglass flow modes, and chemical fertilizers at uniform flow velocities can be prevented from being retained.

Description

Technical field: [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a chemical fertilizer applicator. Background technique: [0002] With the development of agricultural technology, in order to achieve higher crop yields, it is necessary to apply multiple fertilizers at the same time according to the actual situation, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, or other micro-fertilizers, long-acting fertilizers, quick-acting fertilizers, etc., so as to achieve higher yields. In agricultural planting, in order to ensure the nutrients needed for the growth of crops, it is necessary to apply chemical fertilizers containing different nutrients to the crops. At present, fertilization in agricultural planting is mainly carried out by fertilization machinery. [0003] Known chemical fertilizer applicator (as 2T-400 type base fertilizer machine), mainly is made up of fertilization box, transmission shaft, ...

AI Technical Summary

Problems solved by technology

[0003] Known chemical fertilizer applicator (such as 2T-400 type base fertilizer machine) is mainly made up of fertilization box, transmission shaft, belt pulley, and operation efficiency is low, and cost is high

When ammonium bicarbonate fertilizer is applied, it is easy to form cakes, resulting in poor fertilizer discharge, unable to control the amount of fertilizer discharge, causing unnecessary waste and increasing costs
