METHODS AND RESULTS OF THE SEED MATERIAL FRICTION COEFFICIENT DETERMINING USING AN AUTOMATED DEVICE
05.20.00 Processes and machines of agroengineering systems
Description
The article describes the automated method of friction coefficient determination of row crops seeds using different types of surface, including modern polymer and composite materials. It is revealed that the friction coefficient characterizes the friction properties of seeds arising in the process of mechanical action during harvesting, transportation, storage and processing, as well as changes over time depending on the state of the surfaces, contact time, humidity, relative velocity and other parameters. The problem of lack of friction coefficients values for rest and dynamic friction coefficients for the polymeric and composite materials which are actively applied today at industrial production of agricultural machinery is designated. The design and general view of the device which helps to determine friction coefficient excluding the human factor (operator error) are presented. The operation principle of the developed device is described and the processing method of experimental data is given. Experimental data were obtained and statistical processing was carried out to identify the static and dynamic friction coefficients of seeds. Integral ( ) and differential ( ) graph for the distribution of friction coefficient average values for pairs "type of seed material – type of friction surface" are constructed

RESEARCH METHODOLOGY OF THE SPRAY ALIGNMENT EFFECT ON QUALITY INDICATORS OF THE SPRAYER WORK
Description
The article discusses the methodology of the study of influence of the angles of the spray nozzles on the quality indicators. The authors considered three options for placement of dispensers with preset angles. To determine the quality indicators we used a special technique based on the use of a personal computer equipped with a scanner with high resolution for entering information directly to the trapping surfaces

A METHOD OF CALCULATING THE COMBINE PARK IN VARIOUS CONDITIONS OF CLEANING
Description
The article discusses the technique of calculating the combine harvester under various harvesting conditions. The authors consider two options for optimizing the fleet of combines: the first, when the harvested area is set, the second, when the harvested area is not specified. In the first case, the harvester park is calculated for a known area with different harvesting times, but within the boundaries of the agro-industry. In the second variant, a park of harvesters is justified and it is calculated how much space it will be able to clean for a different duration of harvesting operations
