“…To reflect the practical value of the established maize seed assembly model, in this section, the model is used to optimize the performance of the spoon precision seed metering device. Referring to the literature [38,39,45], the RSSW, HA, and SR are selected as experimental factors. A reasonable range of 7-9 mm for SR is obtained by means of DEM simulation tests, while the ranges for RSSW and HA are obtained by consulting the manufacturer and the design specifications, and the value of each factor is listed in Table 4.…”

To improve the sowing performance of the spoon wheel maize seeding machinery, in this paper, two varieties of maize seed are selected as examples. The maize spoon precision seed metering device, a core component of the spoon wheel seeding machinery, is used as the research object. The maize seed assembly model is first established based on the maize seed assembly modeling method. Its validity is verified by the sowing experiment and corresponding DEM simulation under the different revolving speeds of the seed metering wheel. Secondly, the performance of the spoon precision seed metering device is optimized by integrating the maize seed assembly model and multivariate nonlinear regression method. Therefore, the number of sub-spheres of the horse tooth, spherical cone, and spheroid maize seed model are 10–14, 18, and 6, respectively. The results show that the performance of the seed metering device improved when the revolving speed of the seed metering wheel, handing angle, and seed spoon radius are 25 r/min, 40°, and 7 mm, respectively. There is good agreement between the expected results and experimental ones with relative errors of less than 5%, and the optimized seed metering device facilitates the process of seed guiding and seed delivery during the sowing process.

“…Material motion conditions were visually observed through computer programming simulation, which was easy to operate and the results of which were easy to handle. Initial exploration with circular granule can satisfy the simulation requirements [3] , but complicated exterior of corn seed is not able to accurately reflect its real motion conditions.…”

Discrete element method is an important technical tool for analysis of motion law of granular material. Based on the principle of discrete element method, using linear viscoelastic contact mechanics model, simulation calculate for discrete element simulation was developed by MFC. Through the combination of arc modeling a geometric model of the different core seed were built, and simulation of the work process of corn precision metering device was conducted. Suitability of parameters on working procedure of the metering device was analyzed.
