Bio-organic fertilizer screening device

Abstract

A bio-organic fertilizer screening device comprises a feeding assembly, a screening assembly, a first crushing mechanism, a second crushing mechanism and a conveying mechanism, the screening assembly is arranged on the feeding assembly, and the first crushing mechanism is arranged below one end of the screening assembly; the second crushing mechanism is arranged below the other end of the screening assembly; and the conveying mechanism is arranged under the first crushing mechanism and the second crushing mechanism. In the preparation process of a bio-organic fertilizer, screening operation of the bio-organic fertilizer is facilitated, primary crushing of the bio-organic fertilizer can be conducted during the screening operation, refined secondary grinding and crushing can be conducted according to the size of bio-organic fertilizer blocks, the feeding amount of the bio-organic fertilizer can be conveniently controlled, the preparation efficiency of the bio-organic fertilizer is improved, meanwhile, the refining degree of the bio-organic fertilizer is improved, then the quality of the bio-organic fertilizer is improved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the related technical field of bio-organic fertilizer preparation equipment, in particular to a bio-organic fertilizer screening device. Background technique [0002] Bio-organic fertilizer refers to a type of compound of specific functional microorganisms and organic materials mainly derived from animal and plant residues such as livestock and poultry manure, crop straw, etc., which have been harmlessly treated and decomposed, and have both microbial fertilizer and organic fertilizer effects. fertilizer. Compared with traditional fertilizers, organic fertilizers have complete nutrient elements of bio-organic fertilizers, while chemical fertilizers have only one or several nutrient elements; bio-organic fertilizers can improve soil, while frequent use of chemical fertilizers will cause soil compaction; bio-organic fertilizers can Improve product quality, but excessive application of chemical fertilizers leads to poor product q...

AI Technical Summary

Problems solved by technology

[0004] Existing bio-organic fertilizers have low screening efficiency during screening, and the fertilizer is usually transported through a crawler-type transmission device, resulting in a small amount of transport, resulting in low screening efficiency

In the sieving, the fertilizer can only be sieved simply, but the fertilizer cannot be crushed. Usually, it is necessary to use a special crushing device to crush the fertilizer, which also increases the crushing load of the crushing device. The efficiency is low, and graded crushing cannot be carried out, which increases the load on the crushing device and reduces the efficiency of crushing
