Evaluation of combine harvester cutting table mechanisms work quality at the harvest of seed clover crops

摘要

Monitoring of quality of standard combine harvester cutting table mechanisms work in the seed clove crops (meadow clover, sown lucerne) harvest was made in dependence upon stand condition and its moisture. Losses caused by pickup reel were monitored in dependence on #lambda# parameter size. The best kinematic behaviour is at #lambda# = 1.4 - 1.6. The height of stubble is to be chosen with 10 cm, because in this case harvest losses do not arise at normal conditions. With stubble height over 10-15 cm harvest losses increase from 10 to 20%. Stand divider losses were not indicated (0.03-0.06%)
