Agricultural soil loosening fertilizer applicator with screening device

Abstract

The invention provides an agricultural soil-loosening fertilizer applicator with a screening device, and relates to the technical field of fertilization, the agricultural soil-loosening fertilizer applicator comprises a fertilizer applicator frame, the upper end of the fertilizer applicator frame is obliquely provided with a screening box, the upper end of the screening box is integrally and fixedly connected with a fertilizer feeding hopper, and the lower end of the fertilizer applicator frame is rotatably provided with two moving wheel rotating shafts; according to the scheme, fertilizer powder is poured from the fertilizer feeding hopper, caking existing in the fertilizer powder is screened out through the screening box, then the screened fertilizer powder is sucked in from the feeding air box through the dust removal fan, and the fertilizer powder is discharged through the dust removal fan; the secondary screen at the lower end is used for screening secondary-level small cakes, the small cakes fall into the small cake leakage groove and are finally screened through the lower-layer screen, the screened fertilizer slides out of the fine material outlet, and the problems that the fertilizer is affected with damp and is caked, and the fertilizer is not easily absorbed by soil can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of fertilization, in particular to an agricultural soil loosening and fertilizing machine with a screening device. Background technique [0002] When the soil cannot provide the nutrients needed for crop growth and development, the act of supplementing the crops with artificial nutrients is called fertilization. Increase soil nutrients No matter the application of organic fertilizers or inorganic fertilizers can increase soil nutrients. Most of the inorganic fertilizers are easy to dissolve, and the crops can absorb them immediately after application, except that they are partially absorbed by the soil. For organic fertilizers, except for a small amount of nutrients that can be directly absorbed by crops, most of them must be decomposed by microorganisms before crops can use them. For example, a lateral fertilization machine with application number CN201821072106.2 belongs to the field of agricultural fert...

Problems solved by technology

[0003] And above-mentioned technical scheme, when concrete implementation, owing to present fertilizer kind has a lot of kinds, there is no lack of wherein there is some fertilizer powders of phosphorus, potassium, calcium for soil fattening, these fertilizer powders will condense after being damp because of placing for a long time. lumps, sprinkle directly into the soil, the soil is difficult to absorb
