The paper is dedicated to the innovative analytical research in the field of pneumatic separation concerning the issues of grain heap feed for harvester-thresher cleaning, composition of tailings and the amount of grain. The problem of improving the separation of air-sieve cleaning of modern combines is of great current interest. The cleaning design with the use of pneumatic and inertia separator of small grain heaps for high-producing harvester-thresher is developed. The engineering study is conducted for the installation of the 8-bladed rotor above the chaffer sieve for experimental cleaning taking into account dimensional limitations and minimal alteration of the current air-sieve cleaning. The results of the study show the opportunity of better operation of the design of small grain heap cleaning with the application of pneumatic and inertia separator. The developed solutions make it possible to reduce grain losses and increase the harvester-thresher productivity level, as a result of which it is expected to achieve the economic effect assessed in the study.

The effectiveness of combine harvesting processes is one of the most important indicators of planting enterprises, as it largely determines the efficiency of the entire organization. One of the problems in assessing the effectiveness of combine harvesters is the determination of the planned performance of machines with rated productivity. The paper considers approaches to determining the planned and actual performance of the processes of combine harvesting of grain crops. The factors affecting the decrease in the performance of combines have been studied. The analysis of data on the wheat harvesting process in local organizations of the South of Russia during 2014-2019 has been carried out. The results of calculating the planned and actual performance of wheat harvesting processes in these farms are presented.

“…Figure 1 schematically shows the main factors leading to inefficiencies of seeding processes. The main drawbacks of modern seeding units are the limitation associated with high sowing speed, the existence of the oblique impact and the inversion of the seeds, which adversely affects exact positioning of the seeds in the soil, and as a result, there is uneven distribution of the seeds in a row and the complete lack of opportunity to control the sowing process after the seeds have fallen from the disk [1][2][3][4][5][6]. Efficiency can be increased by introducing an automatic system for control and monitoring of sowing quality [7][8][9] into the seeder unit as shown in figure 2.…”

Analysis of the reasons for inefficiencies of grain sowing and harvesting processes

The efficiency of sowing and harvesting processes in agriculture is one of the most important components of the success of an agricultural firm. Natural and climatic conditions typical for the majority of Russian agricultural territories impose restrictions on the timing and the fundamental possibility of sowing and harvesting. Therefore, the low efficiency of sowing and harvesting processes leads to a corresponding decrease in the volume of crop production. A number of works [1-4] consider various approaches to increasing the efficiency of sowing and harvesting, however, a systematic approach to the management of agricultural company processes requires the identification of the most significant reasons for the decrease in the efficiency and addresses as a priority their elimination (or reduction in the strength of their influence). The paper analyzes the reasons for the inefficiencies of sowing and harvesting processes and provides recommendations for reducing the impact of these reasons.
