Test of the mechatronic vibration multiplane seed-cleaning machine

Abstract

The article presents the results of experimental studies of the efficiency of the separation process of seed mixtures of rapeseed and soybean by flat vibration friction surfaces in the laboratory. Information is also given on the testing of the mechatronic vibration multiplane seed-cleaning machine during the separation of the same crops under farm conditions. The working body of this machine has four blocks of non-perforated friction planes (25 pieces in each block), carrying out parallel technological processes of separation of seed mixtures in three modes of movement (non-separable, detachable and shock).The influence of the mode of movement of seed mixtures on the separating surfaces on the quality and productivity of the separation process has been established. As shown by the tests of the machine, high quality separation is achieved with non-separable movement, and the highest productivity – with shock. Household tests of the mechatronic vibration multiplane seed-cleaning machine showed the stability of the separation process under different modes of seed movement along the separating surfaces, the reliability of all components and mechanisms, the low noise level when the machine is operating in different modes and very low labour intensity when the process parameters change. Almost all the adjustments of the separation process are automated – the longitudinal angle of inclination of the separation planes and the frequency of their oscillations, as well as the supply of seed mixtures to the separation surfaces are changed using variable resistors. The tests of the machine under the economic conditions in the separation of seed mixtures of rapeseed and soybean also found its disadvantages. For these and similar crops, and especially for separation in the tear-off mode, the need to develop a special mechanism for loading and removal of fission products. Since the machine must be installed strictly horizontally, for convenience, it must be equipped with level gauges, both in the longitudinal and transverse directions.
