Design method and experiment of machinery for combination of seed fertilizer and herbicide

This study aimed to resolve the problems of full wheat straw returning to the field, which might readily cause stalk obstruction, poor sowing quality, and serious weeds at seedling stage, affecting the growth of maize. Based on the idea of "simultaneous seeding and spraying, closed weeding"...

Description
Summary:This study aimed to resolve the problems of full wheat straw returning to the field, which might readily cause stalk obstruction, poor sowing quality, and serious weeds at seedling stage, affecting the growth of maize. Based on the idea of "simultaneous seeding and spraying, closed weeding", this paper presented a design method of corn seed-fertilizer-herbicide simultaneous operation machine, which focuses on the design of vertical active straw-removing anti-blocking device mechanism, design of nozzle key parameters, nozzle selection, seeding monomer analysis and spatial layout design of seed-fertilizer-herbicide mechanism. In addition, we deduced the interrelated formulas and conducted machine design and field experiment. The experiment results showed that the average variation coefficient of spray uniformity of machines was 17.70%. The post-experiment weed amount was 8.9%, which was lower than that before sowing, 8.5% lower than that before artificially closed weeding, and 14.3% lower than that in unenclosed weeding area. Moreover, the weeds were less in the working area of the machine, and the growth of corn was better. Compared with manual closed weeding, the average plant height uniformity and average stem diameter uniformity increased by 4.4% and 5.1%. Compared with unclosed weeding, the average plant height uniformity and average stem diameter uniformity increased by 18.3% and 10.8%. Overall, the rationality of the design method proposed in this paper was validated, and these can lay a foundation for the research and development of the same type of machine.
