Justification of the Parameters and Operating Modes of the Fan of the Device for Collecting Grain, which is Part of the Reaper Designed for Two-Phase Harvesting in a Batch Way

Abstract

Studies of the reaper designed for two-phase harvesting by batch method, conducted earlier showed the prospects for the development and research of technical means to preserve grain that can already be considered lost. As a solution to the problem, a modernized reaper designed for two-phase harvesting by batch method was developed, in the design of which a device was introduced for collecting grain that came out of the ear in contact with the main nodes of the header, which was called a device for collecting free grain. The fan is an important element of the device for collecting grain, so the justification of its parameters and operating modes described in this article is relevant. In the course of solving this problem, mathematical expressions were obtained that allow us to justify the choice of a fan for the particular case under consideration - for a device for collecting free grain that complements the design of a batch header. The article explains the choice of a specific type of fan. As conclusions on the article under consideration, the results of the conducted research are shown. In particular, the ranges of optimal values of a number of parameters of the considered fan, such as, for example, the power consumption of the fan and its performance, are presented. All the research results shown in the article relate directly to a particular case of a fan - a fan that is part of a device for collecting free grain. © 2022 American Institute of Physics Inc..
