Determination of balanced plow movement for diamond plowing

Abstract

Wider furrow of the diamond-shaped plow bottom allows the energy-intensive tractor to move with right wheels along it and due to it to shift the line of plow traction to the right, unloads side support and reduces the traction resistance of the plow. Replacing field boards on all plow bottoms with common field board, installed on the last plow bottom, changes the application place of the balancing reaction of the furrow side and its size as a result the plough traction resistance changes. In vertical plane of the projections, this corresponds to displacement of the friction force of field board along the action line. The diamond-shaped plow bottom as a result of other form of the cut slice, the application place of resultant soil pressure moved in the horizontal plane closer to the tip of the ploughshare in comparison with the ordinary plow bottom. The investigated diamond-shaped plow bottom is mounted on the tractor according to the two-point scheme with horizontal projection of the central traction through attachment point of the lower traction to the tractor. When considering the scheme of the plough with similar field boards on all bottoms (production), we will represent it with one field board on the medium plow bottom that facilitates theoretical analysis. Efforts are considered as the stationary random time functions and statistic method based on the theories of stationary random processes are used for studying dynamic objects under their influence.
