[0002] With the advancement of science and technology and the development of agricultural modernization, the technology of seeding machinery is also constantly being innovated and improved. A seeder is a type of cultivation machinery that uses crop seeds as the seeding object. It is mainly used to spread seeds evenly on the field. As a modern agricultural machinery, the seeder can greatly improve seeding efficiency and quality, reduce the labor intensity of farmers, and is an indispensable and important tool in modern agricultural production.

[0003] However, existing seeders still have some defects and shortcomings that need to be improved: under the current technology, sowing often requires a lot of manpower to open furrows for corn seed planting and backfill the soil after sowing, which is labor-intensive and has low sowing efficiency, thus affecting the sowing operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 A precision corn planter with double-ridge direct planting and full-film mulching in dryland areas includes a vehicle body connecting frame 10 and several sets of ditching and filling components 20. The vehicle body connecting frame 10 connects the several sets of ditching and filling components 20 to a carrier, allowing the ditching and filling components 20 to be towed by the carrier. Each set of ditching and filling components 20 includes a mounting frame 21, a ditching structure 22, and a backfilling structure 23. The ditching structure 22 is installed below the end of the mounting frame 21 closest to the vehicle body connecting frame 10 and is used for ditching operations; the backfilling structure 23 is installed below the end of the mounting frame 21 furthest from the vehicle body connecting frame 10 and is used for backfilling operations.

[0019] In this embodiment, the trenching structure 22 may include a lifting frame 221, a movable frame 222, at least one trenching cutter 223, a first lifting rod 224, and a spring. The top end of the lifting frame 221 is fixedly connected to the mounting frame 21, and the bottom end of the lifting frame 221 is rotatably connected to the adjacent end of the movable frame 222. The trenching cutter 223 is rotatably connected to the bottom of the movable frame 222 via a pivot. During the movement of the device, the trenching cutter 223 can dig trenches for planting corn seeds in the field. The bottom end of the first lifting rod 224 is hooked onto the movable frame 222, and the top end of the first lifting rod 224 is slidably connected to the mounting frame 21. The spring is sleeved on the first lifting rod 224 and connected to both the first lifting rod 224 and the mounting frame 21. The movable frame 222 can be deflected, and the elastic deformation of the spring allows the trenching cutter 223 to adapt to the undulations of the road surface and automatically adjust its position.

[0020] In this embodiment, the backfill structure 23 may include a swing bracket 231, an axle 232, a compaction wheel 233, several levers 234, a second suspension rod 235, and a spring. The front end of the swing bracket 231 is rotatably connected to the mounting frame 21, and the compaction wheel 233 is rotatably connected to the rear end of the swing bracket 231 via the axle 232. Several levers 234 are formed radially spaced on the outer edge of the compaction wheel 233, and each lever 234 is inclined at a certain angle towards the vertical plane where the center of the compaction wheel 233 is located. During the movement of the device, the rolling of the compaction wheel 233 allows the compaction wheel 233 and the multiple levers 234 on its outer edge to be pushed into the trench and backfilled. The bottom end of the second rod 235 is hooked onto the sway bracket 231, and the top end of the second rod 235 is slidably connected to the mounting frame 21. A spring is sleeved on the second rod 235 and connected to both the second rod 235 and the mounting frame 21. The sway bracket 231 can be swayed, and the elasticity of the spring allows the compaction wheel 233 to adapt to the undulations of the road surface and automatically adjust its position.

[0021] This invention improves sowing efficiency and precision. The seeder integrates furrowing, sowing (although the sowing device is not directly mentioned, it is typically included in such machines, and since the sowing device is not an improvement in this invention, it will not be described further), and backfilling into a single operation, greatly improving operational efficiency. It adapts to complex terrain, enhancing operational flexibility. The combination of a movable frame and springs in the furrowing structure gives the furrowing blades excellent terrain adaptability. Whether in flat fields or uneven dry land, the furrowing blades can automatically adjust the angle and depth according to the actual ground conditions, ensuring consistent and stable furrowing. Similarly, the swaying bracket and springs in the backfilling structure allow the compaction wheel and its levers to flexibly handle various terrains, ensuring the compactness and uniformity of the backfilled soil, reducing the problem of inconsistent soil compaction caused by terrain differences. It reduces soil damage and promotes soil conservation. Traditional farming methods often cause significant damage to soil structure, while this seeder, by precisely controlling the furrowing depth and width and using levers for gentle backfilling, minimizes soil disturbance, protects the soil's microbial community and organic matter, helps maintain soil ecological balance, and promotes long-term soil fertility retention. This is particularly important for dryland agriculture, helping to enhance the soil's self-repair and drought resistance capabilities. It saves manpower and reduces labor intensity. Traditional manual sowing and backfilling operations are labor-intensive and inefficient, while the automated operation of this seeder greatly reduces farmers' labor intensity and improves work efficiency. Through carrier towing, one or more sets of trenching and backfilling components can operate continuously, reducing manpower requirements and making agricultural production more efficient and convenient. This is of great significance for solving the current rural labor shortage problem and promoting agricultural modernization. It can promote the process of agricultural mechanization. The research and application of this seeder is another important achievement in the development of agricultural mechanization, not only improving agricultural production efficiency but also promoting the popularization and promotion of agricultural technology. It provides farmers with advanced production tools, reduces production costs, and improves agricultural production efficiency.

[0022] In conclusion, the invention of the dryland full-film double-ridge direct-insertion precision corn planter not only solved many problems in traditional agricultural operations, but also promoted the transformation and upgrading of agricultural production through technological innovation, making an important contribution to achieving sustainable agricultural development, improving agricultural production efficiency and farmers' income.
