ARTICLE ANNOTATION

quote
The article presents findings from theoretical studies into the parameters of an elevator guide of a carrot digger and indicates the research focus on the scientific and technical solution to the problem. Studies show that due to the variability of soil and climatic conditions when harvesting carrots, it is difficult for diggers to separate roots from the soil, the sifting process gets more complicated and, as a result, the machine becomes overloaded. To solve this problem, the root-soil mass needs to be moved at a certain angle along the surface of the elevator. Moreover, according to agrotechnical requirements, the roots that fall off the elevator should be left on the ground with a width of up to 80 cm. To fulfil the above requirements, we installed a guide on the elevator for digging carrots. To justify the parameters of the guide of the carrot digging elevator, which ensures complete sifting of the sieve mass with minimal damage to root crops by directing them at a certain angle along the width of the elevator and leaving them at the specified width. The geometric, kinematic parameters of the carrot digger elevator guide have been investigated and the design parameters of the guide and its kinematic characteristics are now theoretically substantiated. The rational parameters of the elevator guide for digging carrots have been determined as follows: bй = 20 sm, αй = 28-300, Lй = 40-42 sm, Vс = 0,6 m/s, Snk = 230-236 sm. In order to further improve the screening quality of the carrot digger elevator, it was decided to continue the research by installing a guide at the end of the first elevator and reducing the width of the second elevator to 90 cm.
