Design and Experiment of Electric Drive Single Row Rice Seedling Raising Plate Swing Plate Cover Machine
In order to realize the mechanization of rice seedling cultivation in the shed,aiming at the problems of heavy labor intensity,low production efficiency,long operation time,and most of the existing rice seedling arrangement devices are not suitable for plastic floppy disk in the existing shed seedling cultivation mode.An electric drive type single row rice seedling planting tray tray overlaying machine was designed in combination with the requirements of rice seedling cultiva-tion.This paper describes the structure of the whole machine and the basic principle of the swing plate overburden,and makes a simulation analysis of the overburden belt and the lateral guide rail to verify the rationality of the design.Field experiments were conducted using the variation coefficient of soil cover amount uniformity,surface flatness of soil cover,vertical uniformity of rice plate and transverse uniformity of rice plate as test indexes.The test results showed that the electric drive type single row rice seedling tray tray overlaying machine had a good operation effect,the variation coeffi-cient of soil cover amount uniformity was<3%,the surface flatness of soil cover was<2 mm,and the horizontal and vertical uniformity of the rice tray was≤2 mm,which met the requirements of rice seedling cultivation agronomy and the technical requirements of rice factory.
