Design and Test of Rice Blanket Seedling Separator
At present,the mechanization degree of the rice seedling tray separation link between the seedling raising link and the transplanting link in the rice planting link is relatively weak compared with other links.In order to improve the mechanization level of the whole process of rice and reduce the production cost,a mechanical device suitable for the separation of rice blanket seedlings and plastic floppy disks is designed.The centrifuge is mainly composed of conveying mechanism,separating mechanism,seedling supporting mechanism,seedling collecting mechanism,power system and frame.The structure and working principle of the device are described,and the structural parameters of each mechanism are analyzed and determined.The experiment was carried out with the separation rate,the damage rate of stem and leaf,and the damage rate of substrate as the test indicators.The results showed that the operation effect of the rice diskette blanket seedling separator was good,and the separation success rate was more than 95％,which could reduce the produc-tion cost and improve the production efficiency;The damage rate of stem and leaf and the damage rate of substrate are be-low 3％,which ensures the smooth progress of the subsequent transplanting of rice blanket seedlings.The smaller damage of stem and leaf and substrate also ensure that the subsequent rice growth will not be greatly affected,and meet the agro-nomic requirements of rice seedling cultivation and the technical specifications of rice industrialization.
