| Abstract: |
| Many kinds of quinoa are planted in high altitude and hilly mountainous areas in China with small planting plots, large slopes, and narrow roads. To reduce the problems of large loss, high impurity content and poor feeding of quinoa harvested by ordinary rice wheat combine harvester, this study focused on quinoa planting agronomy and stem characteristics with a new design of hilly and mountainous quinoa combine harvester. The machine used a small row spacing flared chain tooth feeding device, lower cutter, combined longitudinal axial flow threshing drum of corrugated rod and rod tooth, combined separation concave plate, double layer reciprocating vibrating screen and other devices to realize the smooth feeding, threshing, separation and cleaning of quinoa. The key components were designed and simulated, and a field experiment was carried out. The simulation results showed that the feeding angle of quinoa was small, the stalk was damaged. The results showed that when the moisture content of quinoa grain was 14%, the moisture content of stem was 26%, the threshing rate was 96.83%, the impurity rate was 4.30%, the damage rate was 0.15%, the header loss rate was 1.54%, the entrainment loss rate was 0.92%, the cleaning loss rate was 0.52%, and the total loss rate was 2.98%. During the operation, the whole machine ran smoothly and met the requirements and operation indexes of quinoa mechanized harvest. Therefore, it could be used as the quinoa combine harvester in hilly and mountainous areas. This study provides some reference for design and test of quinoa combine harvester. |
