ANALYSIS AND EXPERIMENTATION OF THE CRUSHING AND SEPARATION PROCESS OF THE ROOT-SAND COMPLEX OF HARVESTED AND EXCAVATED Cyperus esculentus L. IN DESERTS

The aim of this study is to simplify the difficult excavation that caused by root-sand complex in process harvesting Cyperus esculentus desert Xinjiang performing mechanical tests and analysis interaction between vibrating shovel rotary blade on complex. number, speed digging depth were used as test parameters, breakage rate, root-grass crushing soil carrying rate indicators. characteristics influence various factors their separation explored. A parameter combination optimization model verified experimental data. results showed optimal was follows: number blades 20, rotational 373 r/min, 12 cm. At time, 2.62%, 63.68% 55.40%, respectively. This can support development a harvester suitable for deserts Xinjiang.
