Machinery & Energetics

The article analyzes the maintenance of existing agricultural machinery in working order, which should work out the maintenance system, taking into account the conditions of reforming the agricultural sector. Operational-technological and functional indicators were determined by direct combining of wheat. Under these operating conditions, the productivity for 1 hour of main time was 17.6 tons, which is slightly less than the technical conditions - not less than 18 tons. This is due to low yields of harvested crops. Self-propelled combine KZS-9M steadily performed the technological process, as evidenced by the value of this coefficient equal to 1, which also corresponds to the value of the technical conditions - not less than 0.98. All indicators of the quality of the technological process: the loss of grain behind the combine thresher and the reaper, the quality of grain from the combine hopper (crushing and the content of impurities) are within acceptable values for technical conditions. For example: grain losses on the combine thresher were received 1.06% (according to technical conditions not more than 1.5%) and on the reaper 0.24% (according to technical conditions not more than 0.5%). During the period of observations according to the data of combines five failures were revealed and all of them of the II group of complexity. The average number of failures of group II complexity was 1.7. The operating time for failure of group II complexity was 307.6 hours (5006.7 tons), which is higher than the technical conditions of at least 100 hours. For four seasons of observations of combines, the average operating time was 1055 hours (11387 tons). Operating time for failure of the II group of complexity at the same time for four years of supervision made 105,5 hours (on technical conditions not less than 100 hours). This indicates sufficient technical reliability of combines. Details (units) that have reached the limit of wear (resource) for four years of observations of self-propelled combine harvesters KZS-9M were not found.
