“…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]:…”

The efficiency of the spindle harvester is determined by the activity of the spindle teeth located on the drums. The well-known M V Sablikov theory of cotton harvesting technology says that the capability of capturing cotton by the spindle depends on the correspondence between the directions of the tip and the speed vector of the tooth point. The article is devoted to the development of an analytical method for determining the active component of the absolute velocity of the tooth point of the spindle in the working chamber of the picking apparatus. The method is characterized by studying the orientation of the absolute velocity vector relative to the tangent to the circle of the section and the bisector of the spindle tooth wedge angle. Having located the centers of the coordinate axes along the tangent and the bisector at the tooth point, the oblique directing angles of the velocity vector were determined, and its active component was calculated. Graphs of changes in velocity during the time the spindle was in the working chamber were plotted, and an assessment was made of the capability of cotton capturing by the working body.

“…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].…”

When modeling gears by means of roller analogues it is necessary to take into account that the degree of slippage is equal to zero in the meshing pole of the gears, in thecontact zone ofinitial circles of the gears. The greatest slippage occurs between the tooth head of the master gear and the tooth foot of the driven gear, and between the tooth head of the driven gear and the tooth foot of the driven gear. Thus, the simulation of the wear process of gear wheels with roller counterparts is achieved by ensuring equality of geometric and kinematic parameters (radii of contact point curvature, degree of relative slippage of the surfaces, friction paths) and contact pressure.

“…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].…”

One of the main ways to increase the productivity of livestock is to feed them with mixed feeds, namely feeds obtained by processing feed grains. Based on this, a constructive and technological scheme for the device for small-scale livestock farms such as maize and other cereals, namely rye, oats, wheat, barley, was developed. On this principle, a two-stage grinder with a fixed blade in the upper chamber and movable hammers in the lower chamber, which performs the work process, was developed, and its upper chamber hole surface dimensions were theoretically and empirically studied. It was found that Nm = 137.5 holes with a diameter of 20 mm are required for the exit of crushed pieces from the crushing chamber under ideal conditions when crushing a piece of corn-cob. In the experiments, the optimum granulometric composition of the primary crushed product was obtained when the holes of the crushing chamber were studied by changing the holes from 10 to 30 mm. According to theoretical calculations, when the holes had a diameter of 20 mm, the optimum granulometric.
