Currently, special attention is being paid to the development of cattle-raising, fisheries and poultry in Uzbekistan. Cattle-raising, fisheries and poultry feeding green forage providing their intensive increasing as well decreases the gathering of additional oil in them. Therefore, a chopping device was produced to cut green crops, such as clover, maize as well legumes. Since the quantity and arrangement of cutter-bars in the rotor depends on the quantity and placement of the cut feeds to be of same length, the quantity of cutter-bars has been explored theoretical and experimental researches. According to theoretical researches, the greater the quantity of cutter-bars in the feed chopping rotor, the greater the work efficiency and the shorter the length of cutting. During the experiments, when the quantity of rotations of the rotor was 1500 rpm and the quantity of rotating of the chopper was 175 rpm, 6 cutter-bars were installed on a rotor with a diameter of 200 mm. It was found that metal consumption and cost were reduced compared to 8 cutter-bars. It is recommended to install 6 cutter-bars on a rotor with a diameter of 200 mm.

The research is directed from the theoretical aspect to the development of the design of a new grinder, characterized by low energy and metal consumption. The work investigates the relationship of geometric parameters and speed modes of operation with quantitative and qualitative indicators of the screw cutter system. It is possible to increase the degree of chopping of the stems only by reducing the average cut length, i.e. by increasing the rotational speed screw knife. The experiments shows the average slice lengths and the corresponding productivity of the screw cutting pair depending on the speed of rotation of the knife. That for compliance with zootechnical requirements, modes n= 550-650 rpm.( lav = 8-4,5 sm ) - with vertical loading, and n=400-450rpm (lav = 5,5-4 sm) – at inclined feed at an angle β = 450. An increase in the frequency of rotation of the knife leads to a sharp decrease in the productivity of the cutting pair. The above numerical examples are selected in accordance with the parameters of the experimental setup and show good agreement with the experimental results.

“…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.
