Mechanized spraying of liquid meliorants

Abstract

This article deals with the process of distribution of liquid meliorants on the surface of their application by means of a device for introducing liquid meliorants. The device itself is attached to the tillage working organ-the plane-cutting leg of the cultivator-deep-digger. In order to determine the quality of liquid spray and its distribution on the application surface, laboratory studies were conducted. The research was aimed at determining the optimal size of the hole diameters of the device to create a high-quality spray torch of the gas-liquid jet of meliorants. In the course of experiments, it was revealed that the rational diameters of the external (D) and internal (d) pipelines of the device for introducing liquid meliorants are D = 7 mm, d = 5 mm.

Performance Evaluation of Tillage Knife Discharge Microchannel

“…The development of a working body for soil cultivation and intra-soil application of liquid mineral fertilizers that is more efficient, environmentally friendly, and applicable for variable-rate application systems (Yamin et al, 2016;Sugirbay et al, 2020) is essential. During the evaluation, the related investigations (Kostikov et al, 2016;Xiuyun et al, 2019;Vasilyev et al, 2020) and design features of current soil-processing tools in operation (sweep paw, knife fertilizers, chisel fertilizers) with mounted spraying elements such as nozzle, pipe, injector, or orifice, have been analysed. Accordingly, innovative novelties of wellknown manufacturers, which engaged in the development and manufacturing of mechanisms, working bodies, and components that exploited in LMF application processes, have been studied.…”

“…A uniform planar subsoil application of LMF gives more effective results (Vasilyev et al, 2020). However, the agricultural equipment for this process that introduces liquid fertilizers in the form of a wide band has not yet been proposed.…”
