The efficiency of using modern chicory harvesting machines often remains unsatisfactory, particularly under difficult soil conditions. The primary factors limiting digging quality are increased root crop damage, their incomplete extraction from the ground, and a high content of impurities in the harvested mass. These indicators significantly depend on both the physical properties of the soil and the geometric parameters of the root crop itself, as well as the design features of the diggers.
To solve this urgent scientific and technical problem, it is necessary to develop analytical-empirical approaches to justify the design-kinematic parameters and operating modes of an improved combined digger. When designing such equipment, real operating conditions should be taken into account, including soil-climatic harvesting conditions and specific agrophysical characteristics of chicory.
Chicory is a valuable raw material for the food and pharmaceutical industries. Its tops can be used as an organic fertilizer that enriches the soil with nutrients, while the root crops themselves serve as an environmentally safe source of renewable energy for bioethanol production.
In terms of morpho-physiological characteristics, chicory is close to fodder carrots, while its cultivation technology and the appearance of its above-ground part have much in common with sugar beets. The quality of the harvesting technological process is determined primarily by the agrotechnical requirements for the crop, the design of the machines, and the layout of their working bodies. The foundation for designing new harvesting equipment must be the systematization of data on the variability of the agrophysical characteristics of chicory (both root crops and tops), as these fluctuations directly affect the design of the working units.
Despite the steady demand for chicory and its processed products, the sown areas for this crop are declining. The main reason for this trend is the insufficient level of mechanization in cultivation and harvesting. It is also important to consider that the accumulation of top mass and dry matter in the roots continues throughout the entire growing season; however, the intensity of this process (in particular, the formation of the rosette) is not constant. It depends on a number of factors: varietal characteristics, weather conditions, planting density, plant nutrition area, and the chosen cultivation technology.
