The Study the Influence of the Parameters of the Operating Elements on the Technological Indicators of the Operation of the Greenhouse Soil Loader and Mixer

Abstract

Preparing and using soil in greenhouses is a laborious and energy consuming process. The lack of specialized technical means hinders obtaining the required quality of soil mixtures. For mixing and loading soil components for greenhouses, a mixer-loader with a screw milling operating element has been developed. One of the main stages in the development of new designs is to determine the main design parameters of the screw-milling operating element, which is the main in the mixing process. The theoretical and experimental studies established the influence of the parameters on the indicators of the efficiency of the preparation of soil mixtures and substantiated their rational values. The shape of the cutting teeth installed on the screw-milling operating element is substantiated. As a result of research, technological indicators were obtained: the mixing quality factor is 0.96...0.98, the moisture and air capacities of the resulting soil mixtures reach 51 and 48%.
