Abstract

The object of research is the conveyor, which is the mechanism of the header for two–phase harvesting by batch method. The aim of the research is to develop the design and technological process ofthe roll portion header, the most suitable for the conditions of arid climate with the justification ofits main operating parameters. In the conditions of the steppe zone of the southern Urals, a separatemethod of harvesting grain crops is more preferable. The analysis of the structures windrowers allowed todevelop a portion of the header. The technological process as a portion of the header includes two phases — mowing and subsequent accumulation of the grain mass on the conveyor, and then upload. The unloaded portions are joined with the stacked in the previous passage – this is how the roll strip is formed. This option of laying the roll can reduce the number of passes in the selection of about 4–5 times in comparison with the basic technology. This allows you to reduce the cost of selection and reduce the impact of heavy machinery on the soil. A special role in the work of the header plays a conveyor. It is established that the thickness of the layer of stems on the Reaper conveyor depends on theworking length of the conveyor and the speed of movement of the unit on the field, the density and diameter of the stalk, the density of laying on the conveyor.

Highlights

The increase in grain production has been and remains one of the main tasks of the agricultural industry
The height of the stand on the harvested field will affect the height of the cut and, the length of the cut part of the plant, which is crucial when laying the beveled mass on the conveyor. It is worth noting the density of the stalk, which can affect the density of the beveled bread mass on the conveyor belt
Based on the agrotechnical data and our calculations, it was found that the optimal speed of the conveyor belt during the accumulation of bread mass on the conveyor is 1.6-2.8 m/s

Summary

Introduction

The increase in grain production has been and remains one of the main tasks of the agricultural industry. In the conditions of the steppe zone of the southern Urals, often a separate method is more preferable. This process largely depends on the quality of the used roller reapers, which are classified according to several criteria: the principle of formation of the roll, the direction of unloading, the type of drive units, the type of aggregation with MES, etc. In accordance with the development Strategy of the Orenburg region until 2020 and for the period up to 2030, it is advisable to develop harvesting machines that reduce grain losses, reduce fuel consumption and soil compaction, increase productivity. The issue of creating and using a header that meets the above requirements, which will improve the process of separate harvesting of grain crops, is relevant
