The Results of Laboratory Studies of the Device for Evaluation of Suitability of Potato Tubers for Mechanized Harvesting

Abstract

The purpose of this study is to substantiate the concept of a device for the evaluation of the suitability of varieties and hybrids of potato tubers for mechanical harvesting from the earliest stages of the selection process and to perform quantitative and structural assessment of damage to potato varieties and hybrids inflicted by the device, simulating the process of the harvester’s separating element operation depending on the machine type and harvesting conditions. The structural and operating diagram of the device for the evaluation of suitability of varieties and hybrids for mechanized harvesting has been developed, and the procedure and results of the study to determine the force action of the separating surface of the developed device on the potato tubers are presented. The device developed in accordance with the proposed conceptual scheme, further calibrated to account for modern potato harvesters would make it possible to conduct targeted selection of varieties suitable for mechanized cultivation, as well as to assess the degree of resistance of potato varieties to mechanized harvesting at early stages of selective and seed production works.

Improving the Efficiency of Screen Type Potato Sorting Machines by a Modification of the Sieve Drive Movement Algorithm

“…Его можно долго хранить без глубокой консервации. Однако именно хранение остается слабым звеном при использовании клубнеплодов [3][4][5]. Закладка вороха картофеля сразу в хранилище прямо с поля приводит к потерям из-за высокой влажности, наличия большого количества почвенных примесей, некондиционных и больных клубней.…”

Collision simulation of potato tubers for mechanized harvesting

“…Mechanically damaged potatoes affect sales and storage and cause huge economic losses to the potato industry (Bentini et al, 2006). Mechanical potato damage during harvest is mainly caused by collisions between potatoes and separators (Dorokhov et al, 2022; Wei et al, 2019; Xie et al, 2020). However, in mechanized harvesting, the deformation and stress distribution caused by the collisions are difficult to observe and record, and the bruises caused by falling are not evident.…”
