Description

Technical Field

[0001] The invention relates to the technical field of precision fertilization, and in particular to a fertilizer discharging device for precision hole fertilization. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility levels. It is one of the material bases of agricultural production and mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc.

[0003] With the popularization of agricultural mechanization, the traditional method of manual fertilizer spreading has been eliminated in large-scale agricultural planting due to its low efficiency. By adding fertilizer discharge equipment to the seeder, fertilizer can be simultaneously spread into the planting trenches during the sowing process, which can greatly improve the efficiency of agricultural planting.

[0004] The Chinese invention patent with patent application number CN202410917712.3 records a fertilizing seeder, which realizes the one-time completion of ditching, soil breaking, sowing, fertilizing, rotary tillage and soil covering by means of a furrowing shovel, a baffle, a soil breaking knife, a fertilizer box, a first connecting hole, a second connecting hole, a sowing tube, a rotary tillage wheel and a covering plate, greatly improving the efficiency of agricultural sowing and fertilization. However, during the sowing process of the above-mentioned seeder, after the seeds are sent into the furrow holes, the fertilizer also falls into the furrow holes immediately. However, since the seeder is always in a moving state during the working process, this causes the fertilizer to fall into the furrow holes in a straight line, so that the fertilizer that first falls into the furrow holes is far away from the seeds, which is not conducive to the seeds fully absorbing the fertility of the fertilizer, and thus has an adverse effect on the growth and development of the seeds. Summary of the invention

[0005] The object of the present invention is to provide a fertilizer discharging device for precision hole-fertilization, so as to solve the problem that in the existing fertilizer discharging equipment proposed in the above background technology, the fertilizer falls into the trench holes in a straight line during the fertilization process, so that the fertilizer that initially falls into the trench holes is far away from the seeds, which is not conducive to the seeds fully absorbing the fertility of the fertilizer and has an adverse effect on the growth and development of the seeds.

[0006] To achieve the above object, the present invention provides the following technical solutions: a fertilizer discharging device for precision hole fertilization, comprising a plurality of fixed components, wherein the fixed components are provided with a fertilizer guiding component and an auxiliary fertilization component, and the fixed components are also provided with a sowing component;
