The separation of light impurities of safflower seeds in the cyclone of the grain cleaning machine

Abstract

At present, the grain cleaning machines used for cleaning safflower seeds are not effective in cleaning safflower seeds due to the high energy consumption, metal and material content. For this reason, in Uzbekistan an energy and resource-saver grain cleaning machine has been developed which meets the needs of the farms in the cleaning of safflower seeds. When cleaning safflower seeds, the unfamiliar compounds in its content, including 2-3% light impurities should be separated. The quality of safflower seeds cleaning from light impurities depends on the number of fan rotations, the slope and height of the suction pipe and the quenching of the separated light impurities depend on the cyclone parameters. According to the theoretical and experimental studies, light compounds falling into a cyclone with a diameter of less than 20 m/km rise with air and fall with large ones. In addition, the rotation frequency of the fan in the grain cleaning machine is 2200 rpm (air flow rate 5.1 m/s), the height of the suction pipe is 70-130 mm and the slope is in the range of 20-40 degrees and the separation of light impurities of safflower seeds were achieved at around 85 percent.

The technique development of non-washing of mineral fertilizers in the soil through the screen formed on the interpolymer complex basis

“…To apply a polymer -polymer complex solution to the soil surface, a system wаs used with a slight re-equipment for the introduction of herbicides, installed on a tractor with a seeder for sowing cotton with a flow rate of 0.6-0.8 l/m2. The event is cаrried out simultaneously with spraying with herbicide on the soil surface during cotton sowing and before each irrigation when cutting furrows (see Figure 1) [12][13][14][15][16][17].…”

Determination of the parameters of the canonical working body of the straw chopper

“…In Uzbekistan, the main part of livestock is cattle and sheep, but today several new industries such as goat breeding, sheep breeding, camel breeding are being established and maintained in small farms [1][2][3]. In the feeding of livestock on small farms, they are fed with roughage, including corn stalks, alfalfa hay, barley, wheat stalks, sunflower stalks, sorghum and concentrated feeds [4][5][6][7][8][9][10]. However, for these small farmers and family farms, manual labor is used to chop coarse feed, due to the lack of chopers that can chop small-sized coarse feed.…”

Method for modeling the process of wear of gear teeth

“…Modern mechanisms and machines contain many moving interfaces, a large proportion of which are gears. This type of mechanical interface is used in almost all areas of agricultural machinery: tractors, harvester combines [1][2][3][4][5], seeders [6], grain cleaning machines [7][8][9], choppers, grinders and others [10][11][12][13][14].…”
