Parameters Of The Innovative Apron Leveling Combined Tillage Machine

Abstract

Under the existing system of pre-sowing soil cultivation for sowing cotton, there is an unreasonably high number of impacts on the soil, unnecessary consumption of energy and material and technical resources. Repeated passage of machine and tractor units across the field contributes to the overconsolidation of the arable layer, delaying the sowing of agricultural crops, and also leads to the loss of soil moisture and, ultimately, to the loss of cotton yield. Replacement of the existing single operating presowing machine-tools with a combined tillage machine allows, by selecting and varying the operating modes of its rotor, to achieve any quality of soil crumbling in one pass of the unit. However, the combination machine has its drawbacks associated on the one hand with the low productivity, and on the other with the unloading of the soil in front of the leveling apron. These disadvantages of the combination machine can be eliminated by using an innovative design of the rotor cover and equalizer apron. The intensity of the impact of both the forward speed and the specific load on the soil of the leveler apron on the formation of the volume of the drawing prism is significant, and it should be taken into account when optimizing the parameters of the innovative leveler apron. Research has established that within the aisles provided for the initial requirements of the machine speed, the rational value of the working length of the innovative apron-leveler, which excludes the repeated impact of the rotor knives on the already processed soil, is 205–220 mm, and the radius of curvature r from the lower rounded part of the working surface -> 101.5 mm.
