## 1 Introduction  
The yield and quality of corn play a critical role in ensuring food security and promoting agricultural production [1; 2; 3]. The technology of precise positioning and sowing of corn involves the use of corn sowing machinery equipped with soil environment sensors, communication modules, control modules, and computer systems in accordance with modern agronomic requirements. The main purpose of this control method is to adjust plant spacing, row spacing, and seeding depth based on soil moisture and fertility factors in the agricultural production site. This is to quantitatively swap seeds in the ideal position within the soil layer. A multi-parameter control method for precise corn sowing can refer to mature cases of industrial control [4; 5]. Precise positioning and sowing significantly reduces the amount of seed used and production costs, ensures the consistency of individual corn growth and development, improves the efficiency of field management, and provides technical support for attaining maximum corn yield potential, water and cost savings, and increased production efficiency [6]. The process of corn sowing is prone to being affected by factors such as unit quality, soil texture, field topography, and surface residues, which can lead to inconsistent sowing depth and poor grain spacing uniformity, thereby adversely affecting corn yield [7; 8]. Inorder to achieve precise synchronization of the seed arranging speed of the planter and the forward movement of the planter, the Precision Planting Company in the US has developed a vDriveTM electric-drive seed arranging system. This system obtains the real-time operating speed of the planter using speed-measuring radar/GPS and adjusts the speed of the planter accordingly. Through controlling the amount of sowing, the uniformity of sowing is improved, changes in row spacing and plant spacing are reduced, and accurate positioning and sowing is achieved [9; 10]. Additionally, the Exact Emerge series of air-suction seed extractors from the John Deere Company in the US has improved the traditional disc-shaped seed tray structure to increase the seed-filling power of the seeds and adapt to the high-speed seed discharge requirements during the sowing operation. To prevent seeds brought up during the rotation of the seed extractor from entering the seed guide chamber and causing replaying, the finger-clip seed extractor design of the Kinze company in the US has been optimized. The seed guide blades on the seed guide belt have also been optimized to enable different seeds to fall in the same position on the seed guide belt, thus improving planting accuracy [11; 12]. Similarly, the British Stan-hay company has developed a high-precision belt-type precision seed arrangement device that replaces the traditional seed arrangement plate with a flexible seed arrangement belt to reduce the height of planting, reduce the slippage and bounce of seeds on the seed bed, and ultimately improve the quality of planting [13]. Lastly, Case IH Company in the US has designed an air-suction seed extractor with a flexible seed stirring finger wheel in the seed box that rotates synchronously with the seed tray. This, in turn, disturbs the seeds in the seed box, reduces the seed separation resistance during the seed filling process, and improves seed fluidity and seed filling performance [14]. [PERSON] et al. 's research revealed that the diameter, length, and inclination angle of the seed discharge pipe have a substantial impact on the uniformity of actual seed discharge. Thus, it is essential to maintain consistency in these parameters to ensure each row's seed discharge consistency [15; 16]. [PERSON] et al. designed a V-shaped groove dial-wheel seed guide component consisting of a V-shaped groove seed guide tube and a flexible sowing wheel [17]. They conducted a multi-factor orthogonal rotation experiment under virtual simulation conditions, obtaining the best structural parameters for the seed arrangement component.
