Improvement of working cultivators design and technological methods

Abstract

One of the most common tillage machines are cultivators. Analysis of operating working discrepancy points to their durability requirements that is in violation of the quality of performance of the process as a result of changes in the shape of the working surface during wear. The analysis of the literature found that the most promising areas to increase durability of the working bodies should consider the use of materials of high durability, optimization and application forms paws strengthening blade. Towards improving the durability of the working bodies of cultivators proposed the following designs. Cutting edge of the first section is made of local strengthening of the upper side of the second section on the bottom of the length of the blades, and the symmetry axis of the lancet paws upper side band performed locally strengthening. Such constructive response of the working body cultivator ensures equal wear intensity at each point of the cutting edge and thus preserve the geometric characteristics paws. The working body cultivator works like this. At recess cultivators paws into the soil at a given depth to perform the process of surface soil due to the fact that the destruction of soil over the pressure soil environment falls on the bow of legs, especially on its upper surface, the cutting edge of the first section is made of local strengthening of the upper side and the second - from the bottom, which will ensure alignment of values ??of dynamic pressure of the soil. At that speed operation of the main and upper and lower local carbide material wings legs, providing samozahostrennya effect the formation of jagged surface with a smooth transition between the cavity and performances, the intensity of wear first and second sections are aligned paws. This provides both areas rivnostiykist blade, maintaining the geometric characteristics of the clutches and increase its durability.
