| Abstract: | For the usage of the spade soil opener in a punch planter the precision metering device with declined scoop type disc was selected for maize seeds. On the basis of analysis of construction characteristics and working ability of the metering scoop the influences of decline angle and revolving speed of the metering device on the working quality defined as percentage of duplicate placement of seeds and variance coefficient of seed distance were observed. Furthermore the optimal combination of the parameters were determined through computer aided design. |
