Study on preparation and distribution of forage by chopping coarse fodder

Abstract

Livestock farming is one of the very important agricultural branches in Uzbekistan. In present days there are a lot of small livestock farms. In cattle farming for increasing productivity it depends on feeding well with different types of fodder of the livestock animals. For this reason, it is necessary for these farms to develop a small chopping machine and distributor device for individual use. According to construction of available fodder-choppers and physical-mechanical properties of the rough fodder, technological schemes of the small scaled chopper-mixer and distributor device were developed. During the experiments the chopping apparatus of the fodder chopper device was researched. When rotation frequency of the rotor was 1000 rpm qualitative chopping of the coarse fodder was determined when diameter of the rotor was 450-500 mm and the number of the knives on the rotor was 24-30 pieces. Next task is making experimental variant of the small scaled fodder distributing device as well testing of performing capability its defined technological process and determination its optimal parameters.

Analytical method for determining the “active” speed of the spindle cotton harvester

“…As mentioned above, the directing angle of velocity vector a V relative to the tangent to the spindle is essential in assessing the activity of the spindle; it can be determined by the tangent of the ratio of the projections of normal velocity Vaпto the tangent velocity Vaτ equal to [1,2]:…”

“…In Uzbekistan, many works underway to develop machines for use in tillage soil, the cultivation and harvesting of various crops [1][2][3][4][5][6][7][8][9][10]. However, cotton harvesting remains paramount.…”

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].…”

Research into the perforated surface of the double staged grinder-crusher

“…With this in mind, research is underway to develop a small crushing device for small farms. In practice, disc, roller, and hammer rotor grain crushers are used [4][5][6][7][8][9][10]. Disc grain crushers were studied by S.Kwofie, P.Toneva, P.Vaculk, M.Lupu, V.Yanovich, I.M.Kupchuk, D.Alijanov and others and determined the performance of disk crushers [11][12][13][14][15][16][17][18][19].…”
