Installation for calibration of seed material of fruit stone crops
Using the tilt angle control, set the desired slope of the screen part. Using the amplitude adjustment mechanism, we set the specified eccentricity. Before starting the unit, by pressing the “start” button on the control panel of the HITACHI X200 frequency converter, the set frequency of vibrations of the screen part for a particular culture is set. When the set oscillation frequency is set, the seed from the hopper is transferred to the upper sieve using the distribution board. Moreover, for cherries and sweet cherries, the thickness of the seed layer on the sieve is equal to two values of seed thickness, and for cherry plums, apricots and almonds – one thickness, to ensure the orientation of the seeds in the holes.

The laboratory setup is based on the TAKI-15 tomato harvester.
A test bench for testing a rod elevator in laboratory conditions has been developed, with the help of which the optimal parameters and operating modes of the elevator have been experimentally determined.
The main objective of the research is to determine the experimental model of the process and justify the parameters for the coefficients of dynamism in terms of force (KF) and pressure ( KP) of the system and the maximum force in the elevator belt. The use of a drive with a damping device leads to a decrease in the dynamic coefficient Kf by 8-9 %, the dynamic coefficient of pressure – by 4-5 %; the starting torque – by 11.5 % at a shaft speed of n = 150 rev/min (w = 16 r/s).
A methodology for calculating the drive of a rod elevator has been developed. This methodology contains an algorithm for determining the dynamic loads in the rod conveyor belt. This methodology and recommendations for improving the design of the elevator drive are used in the design of stationary conveyors.

Wind turbine generator with a verical axis
To supply remote areas or areas with no connection to centralized electricity and heat supply systems, impossibility or excessively high cost of connection to such networks; high cost of fuel importation for generating electricity and heat on site; favorable conditions for the use of primary renewable energy sources, primarily solar or wind.
A wind turbine generator with a vertical axis has two blades that are placed on a shaft at an angle of 90° to each other. The shaft is mounted in bearings on a vertical support. Under the influence of the wind force, one of the blades is always in a vertical position and moves relative to the vertical support half a turn of this support. At the same time, the other blade is in a horizontal position for half a turn relative to the vertical support. Thus, one blade generates torque, and the second blade – at this time in a horizontal position – moves along the line of wind force. When the first blade completes a half-turn, the wind moves it to a horizontal position and the second blade to a vertical position. This process continues for the next half-turn. The torque developed by the shovel in working condition is transmitted by an electric generator.The peculiarity of this design is that the blade position changes automatically under the influence of wind force, as well as the presence of one moving link – the shaft in the sleeve (utility model patent No. 50427).
