Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to an automated corn planter. Background Technology

[0002] Automated corn planters are agricultural machines that integrate land preparation, sowing, and fertilization. They achieve precise operation through an intelligent control system and are mainly composed of a traction device, land preparation components (such as rotary tillers), a sowing unit (including seed box and seed metering device), a fertilization system, and a soil covering and compaction component. During operation, the land preparation components loosen the soil first, and then the seed metering device sows corn seeds into the soil at a set interval. They are suitable for large-scale corn planting, can significantly improve sowing efficiency, reduce labor costs, and enhance the standardization of planting.

[0003] The automated corn planter is driven by a traction device. The soil preparation unit first tills and loosens the soil, creating suitable conditions for sowing. Seeds in the seed box of the sowing unit are metered out by a seed metering device and fall into the seed furrows formed by the furrow opener through a seed delivery pipe, achieving precise seed placement. The fertilization system operates synchronously with sowing, applying fertilizer near the seeds according to a set amount to ensure nutrient supply. The soil covering and compaction component follows, covering the seed furrows with soil and compacting it appropriately to ensure close contact between the seeds and the soil, promoting germination.

[0004] Existing technologies, such as traditional seeders, suffer from numerous problems. During high-speed operation, the seed delivery system is prone to missed or repeated sowing, leading to uneven corn emergence rates and impacting subsequent yield and field management. Furthermore, the furrowing components of existing seeders are ill-suited to complex terrain, making it difficult to ensure consistent sowing depth and resulting in significant variations in seed germination conditions. These issues hinder the improvement of corn sowing efficiency and quality, necessitating design improvements. Therefore, an automated corn seeder is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automated corn planter, which aims to improve the poor accuracy and stability of seed delivery systems in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated corn planter includes a fixed plate, a planter body fixedly connected to the top of the fixed plate, a seed guide groove on the top of the planter body, two seed pressing wheels rotatably connected inside the planter body, multiple drive shafts rotatably connected to the adjacent side of the two seed pressing wheels inside the planter body, seed protection belts sleeved on the outside of the multiple drive shafts, two seed transfer wheels rotatably connected to the bottom of the two seed pressing wheels inside the planter body, two seed storage frames fixedly connected to the distant side of the two seed transfer wheels inside the planter body, two seed protection rings fixedly connected to the top of the two seed storage frames, and a soil loosening component fixedly connected to the bottom of the fixed plate.

[0008] As a further description of the above technical solution:

[0009] The soil loosening component includes a vehicle body, a second seeding opening inside the vehicle body, a movable groove inside the vehicle body (i.e., on the left side of the second seeding opening), an elastic contour shovel slidably connected inside the movable groove, a drive end fixedly connected to the top left side of the vehicle body, a rotary soil loosener fixedly connected to the bottom of the drive end, and a soil gathering shovel fixedly connected to the inside right side of the vehicle body.

[0010] As a further description of the above technical solution:

[0011] A glass is fixedly connected to the front side of the seeder body, and a plurality of rotating buckles are fixedly connected to the opposite side of the seeder body. The rear side of the plurality of rotating buckles contacts the front side of the glass, and two seed inlets are fixedly connected to the top inner wall of the seeder body.

[0012] As a further description of the above technical solution:

[0013] The outer sides of both seed transfer wheels are in contact with the inner wall of the seed storage frame, and the front sides of both seed storage frames are in contact with the rear side of the glass.

[0014] As a further description of the above technical solution:

[0015] Two fixing blocks are fixedly connected to the bottom inner wall of the seeder body. Two elastic seed straightening plates are fixedly connected to the top of each of the two fixing blocks. Seed guide grooves are fixedly connected to the top of each of the two elastic seed straightening plates. Multiple seed carrying rings are opened on the inner wall of each of the two seed transfer wheels.

[0016] A steering wheel is rotatably connected to the right side of the vehicle body, i.e. the right side of the soil-collecting shovel, and a tripod is fixedly connected to the bottom of the steering wheel.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, corn seeds are introduced into and stored in the seed storage frame through the seed guide groove. Then, the seed transfer wheel starts to rotate, and the seed pressing wheel provides pressure to press the corn seeds into the seed carrying ring on the seed transfer wheel, so that they move with the seed transfer wheel. Then, the seed protection belt covers the corn seeds in the seed carrying ring under the rotation of the drive shaft to prevent them from falling off. As the corn seeds on the seed transfer wheel rotate into place, they will fall into the seed outlet under the action of the elastic seed straightening plate, realizing the fully automatic sowing of corn kernels, thereby reducing the occurrence of problems such as insufficient seeds and missing seeds.

[0023] 2. In this utility model, the rotary soil loosener structure initially loosens the soil in the cultivated land. Then, the elastic contour shovel loosens the soil a second time. Under the action of the horizontal limiting ring, the elastic contour shovel can plow trenches of the same depth in cultivated land at different heights, so that the corn seed growth environment is the same. Finally, the soil-collecting shovel covers the cultivated land with soil, realizing the stability of the sowing operation and thus enhancing the adaptability to complex terrain.

[0030] 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.

[0031] Reference Figure 1 and Figure 2 This utility model provides an embodiment including a fixed plate, which serves as the basic support component of the entire seeder. The seeder body, fixedly connected to the top of the fixed plate, bears and protects the internal core sowing components. The seeder body is fixedly connected to the top of the fixed plate, serving the sowing function. A seed guide groove is provided on the top of the seeder body, acting as the initial channel for corn seeds to enter the equipment from the inlet, guiding the corn seeds downwards. Two seed pressing rollers are rotatably connected inside the seeder body. These rollers apply downward pressure, working in conjunction with a seed transfer roller and a seed-carrying ring to tightly arrange the corn seeds for transport. The interior of the seeder body, specifically the side adjacent to the two seed pressing rollers, is rotatably connected... There are multiple drive shafts, which together drive the seed protection belt. The seed protection belt is fitted over the outside of the multiple drive shafts. The seed protection belt assists in the transfer of corn seeds and prevents the seeds from scattering. Inside the seeder body, at the bottom of the two seed pressing wheels, there are two seed transfer wheels that are rotatably connected. The two seed transfer wheels achieve orderly transfer of seeds. Inside the seeder body, at the far side of the two seed transfer wheels, there are two seed storage frames that are fixedly connected. The two seed storage frames are used to temporarily store corn seeds and continuously supply seeds to the seed transfer wheels. At the top of the two seed storage frames, there are two seed protection rings that are fixedly connected. The seed protection rings prevent the corn seeds from overflowing or scattering inside the seed storage frames. At the bottom of the fixed plate, there is a soil loosening component that has a soil loosening function, which breaks the soil and facilitates sowing.

[0032] Reference Figure 1 and Figure 3The soil loosening component includes a vehicle body, which serves as the main load-bearing structure. Inside the vehicle body is a second seeding port, which works in conjunction with a seed transfer component to ensure precise seed placement. On the left side of the second seeding port, inside the vehicle body, is a movable groove providing sliding space for a flexible contoured shovel. The flexible contoured shovel is slidably connected inside the groove. During secondary soil breaking operations, the flexible contoured shovel, through its elasticity, conforms to the ground and, in conjunction with a horizontal limiting ring, plows trenches of consistent depth at different elevations. A drive end is fixedly connected to the top left side of the vehicle body, serving as a power output component that transmits power to a rotary soil loosener fixedly connected at the bottom. A rotary soil loosener is also fixedly connected to the bottom of the drive end. A soil-gathering shovel is fixedly connected to the right side of the vehicle body. After the corn seed falls into the trench, the soil-gathering shovel gathers the soil on both sides to cover the seed. Working in conjunction with the rotary soil loosener, flexible contoured shovel, and other components, it completes the entire planting process from breaking the soil, sowing, to covering the seed.

[0033] Reference Figures 2 to 4 The front of the seeder is fixedly connected to a glass panel, which serves as a visual observation component, allowing operators to directly view the seed transfer and storage status inside the seeder. Multiple rotating buckles are fixedly connected to the opposite side of the seeder body, engaging with the front of the glass to secure it. Two seed inlets are fixedly connected to the top inner wall of the seeder body; these inlets are transition channels for corn seeds to enter the seed storage frame from the seed guide groove. The outer surfaces of both seed transfer wheels are in contact with the inner wall of the seed storage frame, ensuring that seeds do not scatter during transfer through a close-fitting design. Working in conjunction with the seed storage frame, they complete the storage and transport of seeds. The front sides of both seed storage frames are in contact with the rear side of the glass, allowing operators to clearly observe the seed level within the storage frames. These three elements work together to enhance the equipment's visibility and ease of operation.

[0034] Two fixed blocks are fixedly connected to the bottom inner wall of the seeder body. These blocks provide the mounting base for the elastic seed-adjusting plates, ensuring their stable installation. Two elastic seed-adjusting plates are fixedly connected to the top of each of the two fixed blocks. These plates use their elasticity to comb the corn seeds transported by the seed-transferring wheels, ensuring even falling. A seed guide groove is fixedly connected to the top of each elastic seed-adjusting plate, serving as a guide channel for the falling seeds. Working in conjunction with the elastic seed-adjusting plates, it guides the evenly combed seeds to the seed inlet. Multiple seed-carrying rings are formed on the inner walls of both seed-transferring wheels. These rings carry the corn seeds through annular groove structures, working in conjunction with the seed-pressing wheels to ensure tight seed arrangement and orderly transmission. A steering wheel is rotatably connected to the right side of the seeder body, i.e., the right side of the soil-collecting shovel. The steering wheel is the control component; the operator controls the seeder's direction of travel by turning the steering wheel. A tripod is fixedly connected to the bottom of the steering wheel, providing support. Two wheels are rotatably connected to both the front and rear sides of the tripod. These wheels, as the moving parts, work in conjunction with the tripod and steering wheel to achieve the seeder's movement and steering.

[0035] The bottom of the machine body is fixedly connected to two fixed frames, which provide structural support for the equipment and ensure that all components are installed stably. The flexible contour shovel is fixedly connected to a horizontal limiting ring on the outside. The horizontal limiting ring works with the flexible contour shovel to ensure that furrows of consistent depth can be plowed in different terrains. The top of the fixed plate is fixedly connected to a protective shell, which serves as a protective function. The top of the protective shell is fixedly connected to a feed inlet, which serves as a seed delivery inlet. It works with the seed guide groove to facilitate the worker to pour corn seeds into the seeder.

[0036] Working principle: When using the corn planter, the operator first places the protective shell 27 stably on the fixed plate 1. The protective shell 27 not only prevents the corn seeds from spilling but also protects the internal structure of the device. Next, the corn seeds are poured in through the feed inlet 28. Under the action of gravity, the corn seeds slide along the seed guide groove 3 into the seed outlet 13, and then fall into the seed storage frame 8 to accumulate. At this time, the seed pressing wheel 4 starts to operate. Under its pressure, the corn seeds are tightly arranged and moved by the seed carrying ring 26 on the surface of the seed transfer wheel 7. When passing through the elastic seed straightening plate 24, its flexible structure will comb the corn seeds, so that the corn seeds fall evenly and orderly into the seed outlet 14.

[0037] After the material loading preparation is completed, the staff starts the drive unit, and the rotary soil tiller 19 immediately rotates at high speed to perform the initial soil breaking operation and loosen the soil. As the entire sowing assembly moves forward, the flexible contour shovel 17 will keep close to the ground to perform a second deep tillage of the land after the initial breaking. The horizontal limit ring 16 ensures that furrows of consistent depth can be plowed on farmland surfaces with different slopes and undulations. Finally, the evenly arranged corn seeds are precisely placed into the furrows, and the soil-covering shovel completes the soil covering operation, thus completing the automated sowing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
