Combined machine for preparing soil for cropping of melons and gourds

Abstract

Abstract The most important link in the system of measures to ensure a high culture of agriculture and obtaining high yields of melons and gourds is tillage. Success in the cultivation of melons and gourds largely depends on the period and quality of tillage, and tillage depends on the methods of its implementation and the perfection of machine design. The aim of the study is to justify the optimal design of the energy-resource-saving combined machine for preparing the soil for sowing of melons and gourds, and the parameters of its carcasses based on the theory of the interaction of carcasses with the soil layer. The paper proposed a new technology for preparing the soil for sowing melons and gourds in a single pass of the unit, including loosening the aisle between adjacent planting zones, simultaneous formation of irrigation furrow by turning the layers of the planting zone relative to each other, strip loosening the subsurface soil layers and preparing the soil for sowing seeds along the sowing line. The paper presents the design of the developed combined machine for the implementation of the proposed technology. The types and mutual arrangement of the working parts of the machine are theoretically justified. It has been established that with a longitudinal distance from the toe of the plowshare of the combination unit to a flat-cutter 35.1 cm, a longitudinal distance between flat-cutters 42.3 cm and a minimum longitudinal distance between the support wheel and a flat-cutter 24.1 cm, the field is prepared for sowing of melons with minimal costs energy.
