The capacity of modern sowing machines for sowing

Features of functioning of agricultural enterprises, the agricultural holdings are: the territorial dispersion of the SHP, which can be located in several administrative districts of the region within 5-80 km from the Central utility complexes; most are attached SHP minimized engineering base, small engineering and technical services; the cost of seed and tillage systems (PC, PCA) with tractors 5-8 th grade thrust (power diesels 300-500 HP) is 7-12 million rubles. potential yield, in particular a PC, is 150-200 ha/day. at two-shift work, and seasonal production possible in the range of two to three hectares of crop to one set; because of technical and technological failures often skhm, the utilization ratio of working time of shift (day) does not exceed 0,45-0,55. The operational reliability of modern tractors, including imported goods is relatively high. They have a mean time between failures of II and III groups of complexity is 300-600 hours. But the failures of machines in the complexes occur often on the order of their MTBF is an average 15-25 hours. Despite the low complexity of addressing the consequences of failures have skhm (within 0.5 m to 1.5 man-hours), frequency of their occurrence, and most importantly - waiting for the parts of the machine (Schm) or exchange node to restore the PC determine downtime complexes. For comparison of efficiency of use of mashinno-tractor units to conduct observations and collect statistical data for domestic and imported aggregates with tractors of different life. On the basis of statistical material, it analysis the article presents the results: the methodology study of the use of seed combined units of various brands and terms of service, block diagram of the use of units, recommendations for methods of use and maintenance of the units during performance of technological processes in crop production.
