Fertilizer positioning device for hole fertilizer applicator

Abstract

The invention provides a fertilizer locating device for a hole fertilization machine. The fertilizer locating device comprises a land wheel and powder discharging passages, wherein the land wheel is a hollow cylinder; the powder discharging passages are mounted in the land wheel; outlets of the powder discharging passages are positioned in the outer surface of the land wheel. Powder is loaded in the hollow land wheel, the powder discharging passages are arranged in the land wheel, and the powder flows out of the powder discharging passages, so that positions of fertilization holes are marked.

Description

Technical field [0001] The invention relates to the technical field of a hole fertilizer applicator, in particular to a fertilizer positioning device for a hole fertilizer applicator. Background technique [0002] China is a large agricultural country with thousands of years of farming civilization. In traditional farming culture, artificial ridges, holes, and farm fertilizers are used before planting or transplanting cash crops. In the 1970s, farmyard manure was gradually replaced by chemical fertilizers. However, due to the high fertilizer efficiency of chemical fertilizers, the use of traditional fertilization methods that chemical fertilizers are too close to the roots of crops will cause root burning. In order to avoid this phenomenon, many farmers in the past Sprinkle chemical fertilizer on the surface of the cultivated land, and then use a ridger to raise the ridge. This method of fertilization is not efficient and wastes fertilizer. Later, in order to improve fertilizer ...

AI Technical Summary

Problems solved by technology

Among them, the rotation of the ground wheel drives the metal transmission chain to rotate, and then drives the fertilizer applicator to rotate, so that the fertilizer in the fertilizer box falls into the fertilization pipe, and finally falls into the soil, which realizes strip fertilization of the soil, but cannot realize the fertilization of crop plants. Acupoint fertilization still has the phenomenon of wasting fertilizer

For the method of realizing hole fertilization, the applicant submitted an invention patent titled "Hole Fertilization Mechanism for Ridging Fertilizer Applicator" on the same day, which mentions that a stopper plate is set at the bottom of the fertilizer pipe, and the stopper plate is placed on the ground wheel of the fertilizer applicator. During the rotation process, the lower fertilizer pipe is intermittently blocked to realize hole fertilization, but if the fertilization hole cannot be accurately found after hole fertilization, the crop plants cannot be planted near the fertilization hole, which still causes waste of fertilizer
