Granular fertilizer applicator

Abstract

The invention discloses a broadcasting mechanism for a bulk-grain-shaped fertilizer. The broadcasting mechanism comprises a fertilizer bucket, wherein the fertilizer bucket is fixed on a movable rack; a conveying part is arranged on the position of a discharging opening in the bottom of the fertilizer bucket; a scattering part is arranged below the discharging opening; the conveying part and the scattering part are connected with a driving system to realize power driving; the conveying part comprises a conveying rotary shaft and an agitator fixed on the conveying rotary shaft; the scattering part comprises a scattering rotary shaft and a fertilizer broadcasting plate fixed on the scattering rotary shaft. When the fertilizer in the fertilizer bucket is conveyed, a conveying mechanism can be used for initiatively crushing the block-shaped fertilizer, has the strong commonality on organic fertilizers with different physical behaviors and particularly has the smooth discharging effect and the uniform fertilizer discharging and fertilizer broadcasting effects on a hardened organic fertilizer. The broadcasting mechanism for the bulk-grain-shaped fertilizer is small in volume, flexible to operate and low in cost, and is suitable for broadcasting work in small fields in hills and sloping fields of hummocks; the broadcasting mechanism can be directly hung at the tail of a container of a tumbrel and the organic fertilizer broadcasting work in large fields or the broadcasting work of bulk-grain-shaped materials or powdery materials can be realized by moving the tumbrel.

Description

technical field [0001] The invention belongs to a fertilization mechanism, in particular to a fertilizer spreading mechanism for granular organic fertilizers. Background technique [0002] If organic residues and poultry manure are returned to the field without treatment, not only will the fertility not be fully utilized, but also the insect eggs and pathogenic bacteria they carry will be brought back into the field, causing pathogenic bacteria to contaminate. hinder the growth and development of crops. With the rapid development of scale and intensification of the livestock and poultry breeding industry, it provides convenience for the collection, utilization and treatment of poultry manure. Coupled with the increasing development of science and technology, the organic fertilizer processing equipment is becoming more and more mature, and a large number of organic fertilizer processing equipment has appeared. The development of commercial organic fertilizer has injected str...

Problems solved by technology

[0004] According to the special geographical environment of our country, the landforms in the south are mostly hills, and the cultivated land is mostly small fields. Compared with the actual situation in our country, the existing organic fertilizer fertilization equipment will have the following shortcomings when used in the south: large volume, not suitable for Spreading operations in small fields in the south; if fertilization is uneven, reciprocating spreading operations should be used to achieve relatively uniform fertilization and increase the number of soil rolling; the versatility of organic fertilizers with different physical properties is poor, and the humidity is high. Agglomerated organic fertilizers are easy to clog; fertilizer application mechanisms are expensive and difficult to popularize
