Soil preparation machine parameters for the cultivation of cucurbitaceous crops

Abstract

Abstract The combined machine allows qualitatively preparing the soil for sowing melon crops with minimum energy consumption. The efficiency of the combined machine depends on the type, location of the tiller relative to the body, and its parameters. The purpose of the study is to justify the type and parameters of the tiller combination machine to prepare the soil for sowing melon crops. In researches methods of classical mechanics are applied. The construction of the combined machine with soil cultivators is given. Based on the theory of soil destruction wedge determined the main parameters of the soil tinker. Experimental research of different types of soil cultivators is carried out. it is established that at the performance of soil cultivator of the combined unit in the form of a three-sided wedge with an inclined stand, the minimum longitudinal distance from a ploughshare of the case to soil cultivator is 52.7 cm, transverse distance from the field cut of the hull to the tiller bit is 15 cm, width and length of the tiller bit is 5 and 14 cm respectively, cutting angle of the bit is 18 degrees, quality crushing of sub-powder soil layers with minimum energy consumption is provided.
