Design of the precise dosing unit in the system of nfluence of liquid fertilizers
Abstract
With the development of agriculture, the demand for the use of fertilizers and drugs to achieve the maximum yield in the fields increases. One of the important stages for obtaining a good harvest is spraying and application of liquid fertilizers. Only in the last 10 years in Ukraine, the volume of application of liquid complex fertilizers, microfertilizers, nitrogen fertilizers and drugs has increased four times. Liquid fertilizers are poured using special systems. The main element of the pouring system is dispensers of various types. The main features of modern models of dispensers for pouring liquid fertilizers have been determined. Their advantages and disadvantages are revealed. The work presents a classification of the main methods of controlling the liquid pouring system. In the work, a new design of a dispenser with a piezoceramic motor has been proposed and manufactured. In the experimental model, a new technical solution for regulating the flow rate is used. The proposed and developed dispenser is universal, it contains a metering washer with different or identical holes, which allows to quickly change or adjust the rate of pouring, and also allows to use it with different densities of liquid fertilizers. Also, a big plus of this dispenser is that it has practically no clogging of holes. Different versions of dosing washers, with the same holes and holes of different calibers, are also offered, which will significantly increase the efficiency of the system. The hydraulic scheme of the developed stand for checking and determining the parameters of dispensers is presented. With the help of the developed stand, the dependences of hydraulic characteristics of the developed dispenser are experimentally obtained. Research results can be used in the design of dispensers for pouring liquid fertilizers
