Design and physical model of an electromechanical plant sprayer

Abstract

The article explores the experience of developed countries in creating and implementing mobile electromechanical devices for plant processing, highlighting the low energy efficiency indicators and high fuel and lubricant costs of equipment running on organic fuel in the republic. The study emphasizes the relevance of transferring agricultural tractors with electric drives in the context of Uzbekistan. The composition and degree of structural compatibility of the mobile electromechanical device were designed based on operating modes, creating opportunities for organizing general services for farms. The energy efficiency indicators of a mobile electromechanical device powered by centralized and mobile energy sources were analyzed, determining that charging from a mobile power station operating on renewable energy sources is optimal. The following parameters were established for the area that can be processed by a mobile electromechanical device in one load (when hanging grain fields): equipment weight (including working solution and battery) - 420 kg, operating speed sprayer speed 11 km/s, and electric motor power 5.8 kW. Based on these parameters, the area that can be processed in one load is 2.46 hectares. This study provides valuable insights into the potential benefits of using mobile electromechanical devices powered by renewable energy sources in Uzbekistan's agricultural sector.
