Improving the tiller design

Abstract

The article is devoted to the improvement of the tiller designed to operate on rocky soils. The elements of the interaction theory between the tiller work tools and the rocks in the soil are presented. Two cases of the machine blade hitting a rock were analyzed. The improved machine design containing safety devices and a digital alarm system that reports the operator on the safety device response is proposed. Safety devices are installed on each machine section, which reduces the area of untilled soil during their response. A contactless sensor is installed above each section, the signal from which is analyzed by a measuring device according to a special algorithm. Rational values for the main parameters of the tiller section fuses are determined and the time of the section blade hit a rock is studied. The improved tiller sample testing of 2020 and 2021 on rocky soils in the mountainous terrain proved the efficiency of the proposed design.
