Justification of parameters of a universal flax harvester

Abstract

The article justifies the design parameters by coordinating the work of variables and permanent mechanisms of universal flax harvesting machines. Schemes of variable mechanisms are constructed and their main parameters are justified. The use of a universal flax harvester, which can perform separate operations at different times and may have interchangeable apparatus, eliminates the risks of flax harvesting. Thanks to this, both combines and separators can be applied, which will increase the efficiency of the harvesting operations. In this regard, it is advisable to carry out research and development work to create a cheap and easy-to-use flax harvester with interchangeable machines.
The thesis is devoted to theoretical and experimental research and studies of removable nodes of flax-harvesting machine-pulling and picker-turning devices to ensure versatility of flax-harvesting machine, and its use for combining and separate harvesting.
For solution of the raised problems particularities of two ways of harvesting flax have been analysed, scheme of flax-harvesting machine with removable devices is offered. Belts transmissions of removable devices were investigated. Distribution of pressures in transverse creeks of pulling device when working was determined. Transition of stalks from transporting channel to the channel of transverse transporter of flax-harvesting machine was investigated. Work and location of scrapers of pulleys and rollers, was studied. Consumed power of flax-harvesting machine when working was determined. Tests on comparison of combine and separate technologies of flax harvesting were conducted. Field tests of universal flax-harvesting machine equipped with the developed pulling device transporter and the same machine with picker-turning device were conducted and economical effectiveness of machine was determined.
Keywords: universal flax-harvesting machine, flax, pulling device, picker-turning device, pulley, roller, belt.
