Improvement of housing with knives crushers for non-tillage technology

Abstract

The paper gives justification of the options of the housing with crumbling knives for non-tillage technology. The dumpless housing with crumbles carries out intensive crumbling of the soil of the lower and middle arable soil layer. The body consists of a ploughshare, a ploughshare expander, knives and a chisel. When determining the parameters of a non-shaft housing based on a ploughshare, adopt a triangular wedge. Analytical dependences for determining the parameters of the components body without shaft are obtained. According conducted theoretical studies, without a tipper is 0. 45 m, entry angle the ploughshare on the soil is 25°, nook of installation relative to the direction of travel is 42°, corner of installation with respect to the bottom egate is 35°, grinder the blade quantity 4, the elevated is 35 mm, the longitude is 120-140 mm, the angle of installation regarding the direction of peregrinate is 10°, the installation related to the skyline is 30°, the height body sans a tipper is 420 mm processing is provided.
