Abstract

USE OF MATHEMATICAL MODELLING METHODS OF THE OPERATION PROCESSES OF A HYDROSEEDING APPARATUS

S.M. Deyneka

 

The article deals with theoretical investigation of hydroseeding of germinated seeds of small seeded vegetable crops.

The theories of pneumatics and hydraulics, simulation modelling of the processes were used. It is shown that the optimization criterion is the even seeds distribution in a row which includes even seeds distribution in the liquid volume and the standards of pouring of water and seeds mixture.

Attention is drawn to scientific basis of designing and working principles of hydroseeding apparatus for sowing of small seeds of vegetable crops.

The article gives an analysis of mathematical models of some processes which allow to divide the process of designing of the hydroseeding apparatus into the following phases: bubbling, mixing seeds in the liquid and pouring of water and seeds mixture.

It is stressed that the use of the complex of physical processes allows to reach high quality of hydroseeding of germinated seeds without their damaging.

Theoretical investigations of hydroseding help formulate the main areas of experimental research of both separate processes and a general one. Optimisation of their operating modes permits to design a hydroseeder. In this way it is possible to shorten the period of having harvest of vegetable crops by reducing the period of sprouts emergence.
