Abstract
Description
Technical Field
[0001] This application relates to the field of corn planting technology, and in particular to a high-yield corn planting device with alternating wide and narrow rows and a two-plant triangular planting pattern. Background Technology
[0002] By alternating between wide and narrow row planting, the traditional equal-row spacing method is changed, optimizing light and ventilation conditions between corn plants, improving light energy utilization and carbon dioxide supply, thereby promoting corn growth and development. Planting two corn plants in each hole increases the number of plants per unit area, which is beneficial to increasing corn yield. At the same time, double-planting can also enhance competition between plants, promoting root development and nutrient absorption.
[0003] A search revealed that the public disclosure number N205694085U describes a deep tillage rotary tiller for alternating wide and narrow row fallow planting of corn. It features two symmetrically mounted V-shaped deep tillage shovels on the feed tube. The width of the rotary tillage blades matches the working width of the V-shaped deep tillage shovels and is located on the same longitudinal tillage zone. A non-tillage zone is left in the middle of the machine. It is suitable for land preparation in alternating wide and narrow row fallow planting patterns for corn. The V-shaped deep tillage shovels can loosen the soil to a depth of 25-45cm, achieving all-around deep loosening without damaging the soil structure. After deep loosening, it breaks up the subsoil and creates a rat hole, while simultaneously leveling the surface. The entire soil is gently vibrated, which is beneficial for moisture retention, water storage, salinity removal, and aeration.
[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: The deep-plowing component in the aforementioned patent is maintained by an elastic support rod to ensure the consistency of sowing, but it is not made of relevant sturdy and durable materials. During the movement, the feeding component may be subjected to various impacts and vibrations, resulting in instability and thus failing to accurately stop at the predetermined position so as to accurately place the seeds on the hole spacing, thereby causing problems such as bald tips and premature aging in densely planted plants.

[0044] Corn seeds are loaded into the seeding box 1, and the width adjustment component 6 is adjusted to the desired row spacing. The DC motor 62 and stepper motor 72 are then started. The DC motor 62 drives the width adjustment component 6 to fine-tune the row spacing, while the stepper motor 72, through the coordinated action of the drive shaft 73, alloy worm gear 74, and locking gear 75, prepares for precise sowing by the sowing locking component 7. Seeds enter the distribution box 3 from the seeding box 1 via the connecting pipe 4, are then precisely positioned and conveyed by the feeding component 5, and finally fall into the predetermined hole spacing through the inverted conical sowing cylinder 56. During this process, the sowing locking component 7 ensures that the seeds remain stably in the hole spacing, preventing sowing position deviation. As the moving support 2 moves smoothly, the device continues the sowing operation. Simultaneously, the width adjustment component 6, based on the preset planting mode and farmland environment, achieves precise adjustment of the row spacing and alternating wide and narrow row planting through the coordinated action of the DC motor 62, threaded rod 65, transmission gear 12, and sliding plate 66. The feeding assembly 5 delivers seeds to the predetermined sowing position through the precise cooperation between the telescopic tube and the inverted conical sowing cylinder 56. At the same time, the sowing locking assembly 7 ensures that the seeds can remain stably on the planting hole spacing through the meshing of the locking gear 75 and the rack 8. The entire device achieves automation and intelligence in the sowing operation through the drive and control of automated components such as the stepper motor 72.
[0045] The beneficial technical effects of the alternating wide and narrow row spacing, double-plant triangular-shaped corn high-yield planting device according to the embodiments of this application are roughly as follows:
[0046] By introducing the seed-locking component 7, the device ensures that the seeds remain stably at the predetermined spacing during the sowing process, avoiding seeding position deviation caused by vibration and impact. This not only improves the accuracy of sowing but also helps to achieve uniform distribution of corn plants, thereby optimizing light energy utilization and ventilation conditions, laying the foundation for high corn yield. In addition, the introduction of the width-narrow adjustment component 6 enables the device to easily realize alternating wide and narrow row planting patterns. This planting method helps to improve field ventilation and light transmission conditions, reduce the occurrence of pests and diseases, and also facilitates mechanized operations and field management.
