Estimate of parameters of retreat cutting equipment components for peatlands

The article addresses the necessity for new equipment systems for peat cutting and processing. The conventional peat cutting technology by slices and its disadvantages are described. A retreat peat cutting technology and equipment for its implementation are proposed. The components of the equipment system and their structural compositions are presented. The constitutional formula of the proposed equipment system is set up. The estimation of the travelling resistance forces of mining machines on the surface of an undrained peatland is discussed. The experimental and theoretical research of the machine travelling allowed recommending on decreasing the tractive effort required to move the machine system. The effect of change of the frontal angle of the machine understructure is revealed, and the choice of material for the platform underbody is substantiated. The process of penetration of the cutting tool in peatland is analyzed. The expressions are proposed for assessing the unit penetration force of the cutting edge of the bucket in a half-space as function of the penetration depth of a wedge. With regard to L.S. Amaryan’s studies, the expressions are derived to estimate the penetration force in the depth range from the peatland surface and penetration to 5 m.
