Description

Portable accurate fertilizer placement drill

Technical Field

The invention relates to the technical field of topdressing devices, in particular to a portable accurate topdressing device.

Background

The top dressing is an important link of crop nutrient management and is also an important technical guarantee for high quality and high yield of agricultural products. The main purpose of top dressing is to supplement the deficiency of base fertilizer, meet the large demand of crops for nutrients in a certain growth and development period, and improve the yield and quality of crops. At present, the crop topdressing in China still mainly adopts manual operation or simple machine operation, and the fertilizer application has the defects of high labor intensity, low efficiency, uneven fertilizer application, inaccurate dosage and influence on plant growth and crop yield. Certainly, a plurality of large additional manuring machines are popularized and applied at home and abroad, and a complete additional manuring system is formed for different crops. However, these large top application machines are mainly applied to plain areas or large farms with large areas, are difficult to use in many areas with scattered farmland areas or areas where farmers mainly operate in China, and are not difficult to popularize and apply in the future. Particularly for crops with larger plant types (such as corn, tobacco and the like), a good topdressing machine is not available at present. Therefore, agricultural producers are eagerly looking for small-size portable topdressing devices, which can reduce labor and cost, and can realize precision, high efficiency, guarantee crop nutrient requirements and high yield and high efficiency.

Small topdressers or portable topdressing machines have been developed and are also used in agricultural production. For example, "a manual top dressing device" (patent No. CN 202021592506.3) proposed by Zhangxusheng et al, "an accurate top dressing device for corn planting" (patent No. CN 201910959871.9) proposed by Houyupeng et al for corn top dressing, "an intelligent tobacco quantitative hole top dressing device" (patent No. CN 201310613325.2) proposed by Yuanyuan slope for tobacco production, and the like. However, these topdressers have problems of complicated structure, difficult operation, heavy weight, inconvenient carrying, inaccurate control, inadequate topdressing and the like. Therefore, a portable precise fertilizer applicator is urgently needed to meet the requirements of simple, precise and quantitative fertilization, and achieve the purposes of reducing labor and cost, precisely and efficiently fertilizing, and achieving high and stable yield of crops.
