Abstract

Abstract This paper deals with the investigation of the performance of a nozzle used for intra-soil application of liquid mineral fertilizers (LMF), determination of the range of spray angle, fall angle, droplet size, spray distribution characteristics, and substantiation of its dependence on the nozzle design parameters. The proposed nozzle has a jet-impact channel and deflector slot design with very compact overall dimensions. It can be mounted on a deep tillage knife (wing) with a height of 12–14 mm and provides flat fan spray with a high spraying angle. The following range of effective parameters has been determined: the feed channel diameter is 1–1.6 mm, the slot height is 0.35–0.7 mm, and impact surface diameter 5–8 mm. The resultant spray angle is 170–175°, and the fall angle diapason is 5–10°. These parameters contribute to determination of the tillage knife design parameters such as knife height and the height of spray window, as well as the nozzle installation parameters such as t, n and m in future studies. The results can be useful for nozzle industries, particularly in developing the flat fan nozzles with wide spray angle. Overall, the nozzle design is applicable to use for intra-soil application of liquid mineral fertilizes with deep tillage knives.

液体矿物肥料土内施用扁平喷嘴

摘要本文研究了用于土壤内施用液态矿物肥料（LMF）的喷嘴的性能，确定了喷雾角度、落角、液滴大小、喷雾分布特性的范围，并证实了其对喷嘴设计参数的依赖性。所提出的喷嘴具有射流冲击通道和偏转器槽设计，总体尺寸非常紧凑。它可以安装在高度为12–14 mm的深耕刀（翼）上，并提供高喷雾角度的平风扇喷雾。确定了以下有效参数范围：进料通道直径为1–1.6 mm，槽高为0.35–0.7 mm，冲击面直径为5–8 mm。由此产生的喷雾角为170–175°，下落角底倾角为5–10°。这些参数有助于在未来的研究中确定耕作刀的设计参数，如刀高度和喷雾窗高度，以及喷嘴安装参数，如t、n和m。研究结果可用于喷嘴工业，特别是开发宽喷雾角的平风扇喷嘴。总体而言，喷嘴设计适用于使用深耕刀在土壤内施用液态矿物肥料。
