Irrigation and Melioration

Abstract

Investigations of the design of a combined machine equipped with an innovative casing and a leveler apron are presented, and the parameters of the leveler apron are substantiated. It was experimentally established that when the height of the drawing prism is exceeded by more than 200 mm, due to the falling of the crumbling part of the soil onto the rotor, the soil is thrown forward in the direction of the machine. Therefore, to eliminate soil waste, it is necessary either to reduce the height of the drag prism, or to increase the distance between the rotor and the leveling apron. However, in the latter case, the overall dimensions increase, hence the weight of the machine, which is undesirable. The rational value of the working length of the leveler apron, which excludes repeated exposure of the rotor knives to the soil, is 205–220 mm, and the radius of curvature rз from the lower rounded part of the working surface is р > 101.5 mm.
