Estimation of dimensional and qualitative parameters of work of the horizontal disk batcher

Abstract

The large unevenness of fertilizer sifting by centrifugal spreaders is explained by the following reasons. First, it is a manifestation of the technical features of the spreading of fertilizers by the centrifugal body. The second is the influence of physical and mechanical properties of bulk fertilizers and the third reason is the great inaccuracy of fertilizer supply through the metering window of the device on the spreading disk. It is established that stages of their flight. Thus, it is possible to achieve an improvement in the quality of distribution by significantly reducing the width of fertilizer spread by each individual disk, reducing its diameter. In order to improve the quality of fertilizer sifting, a multi-disc device for mineral fertilizer sieving on the field surface is proposed. It is proposed to make the device in the form of independent, functionally independent modules. Each module consists of three independent blocks: fertilizer tanks with a mixer; horizontal disk dispenser with calibration holes; horizontal spreader plate. Each of the units is equipped with an individual electric drive. This implementation makes it possible to adjust the dosage of fertilizers on the spreading plate and the range of spreading fertilizers, by individually setting a certain number of revolutions of the rotation of the dispenser disk and the spreading plate of fertilizers. This layout does not limit their number and location on the frame, and the width of the capture unit will be governed only by their number and range of fertilizer spread by each individual unit. As a result of researches of the model sample of the batcher with active compulsory-portion dosing of loose mineral fertilizers its satisfactory working capacity is received. But studies have shown that the amount of filling the holes of the disk depends on the speed of its rotation and the dimensional parameters of the loading and unloading windows, as well as the presence of the curb located at the end of the loading window. The curb prevents the fertilizer layers from shifting relative to each other and the surface of the rotating disk, thereby improving the filling of the holes with fertilizer.
