| Abstract: | In order to realize the maize precision sowing, a new spoon shaped seedmeter was specially designed for punch planter. After the key data of the seedmeter was decided, and the analysis on its working principle and process was made in this paper, which led to the key factors and critical conditions that would affect the functions of the spoon shaped seedmeter. The orthogonal experiment was made which took the seed tube bending angle, seed height and velocity as factors and took single seed rate and cavity rate as index. The experimental data analysis showed that optimal parameters of spoon shaped seedmeter were 90 degrees seed tube bending angle, two-thirds radius of punch planter seed height, 0.86 meters per second velocity. The tests showed that the spoon shaped seedmeter was satisfied with the maize precision sowing. |
