Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, and specifically relates to a corn planter. Background Technology

[0002] In agricultural planting, corn is an important food crop, and the degree of mechanization in its planting process directly affects planting efficiency and yield. Currently, corn planters on the market typically integrate planting and fertilization functions for integrated operation. However, existing corn planters still have the following shortcomings in the design of their fertilization mechanisms: 1. Insufficient precision and poor adaptability in fertilizer application adjustment: Traditional seeders often use fixed discharge ports or simple mechanical adjustment mechanisms for their fertilizer application, making it difficult to accurately adjust the fertilizer application based on factors such as corn variety, soil fertility, and planting density. For example, when soil fertility is low, a fixed discharge port can easily lead to insufficient fertilization, affecting corn growth; while when it is necessary to increase the fertilizer application, traditional adjustment methods often involve manually changing different sizes of discharge components, which is cumbersome and has low adjustment precision, making it difficult to meet the needs of precision planting.

[0003] 2. Poor uniformity of fertilization affects crop growth consistency: Existing fertilization systems often suffer from unstable fertilizer discharge due to uneven fertilizer particle size and design flaws in the discharge port structure, leading to localized accumulation or leakage. For example, some seeders use a rotary feeding structure but lack dynamic control over the discharge rate, easily causing uneven fertilizer distribution within the same furrow, resulting in uneven growth of corn plants and reduced overall yield.

[0004] In summary, existing corn planters have some shortcomings in terms of the adjustment precision, uniformity, and collaborative operation capabilities of their fertilization mechanisms, making it difficult to meet the demands of efficient and precise planting in modern agriculture. Therefore, there is an urgent need to design a corn planter that can flexibly adjust the amount of fertilizer applied according to planting needs and ensure uniform fertilization. Utility Model Content

[0005] This application provides a corn planter that can flexibly adjust the amount of fertilizer according to planting needs and ensure the uniformity of fertilizer application, in order to solve the problems of adjustment accuracy, uniformity and collaborative operation capability of the fertilizer application mechanism in existing corn planters.

[0006] To achieve the above objectives, this application provides a corn planter, including a frame, an engine fixedly mounted on the frame, the power output end of the engine being connected to a wheel via a first pulley assembly, the wheel being mounted on the frame; a seeder is also mounted on the frame, the power input end of the seeder being connected to the power output end of the engine via a second pulley assembly, the power output end of the seeder being connected to a fertilizer applicator via a sprocket assembly, the fertilizer applicator being mounted on the frame; The fertilization mechanism includes a fertilizer bin, which is fixedly connected to the frame via a support rod. A discharge adjustment component is rotatably installed at the discharge end of the fertilizer bin. The power input end of the discharge adjustment component is connected to the power output end of the seeder via a sprocket assembly, and a knob is installed at the other end. The fertilization mechanism also includes a scraper, with one end of the scraper set on the fertilizer bin and the other end sliding against the discharge adjustment component.

[0007] In one embodiment, the discharge adjustment component includes a wave roller, which is rotatably disposed at the discharge end of the fertilizer bin. Multiple isolation bins are evenly arranged around the circumference of the wave roller, and the multiple isolation bins form a material holding bin in pairs. A slide rail is provided through the side wall of the isolation bin, and two guide rings are symmetrically slidably disposed through the slide rail. A linkage component is installed inside the isolation chamber. One end of the linkage component is connected to the guide ring, and the other end is connected to the adjustment component. The adjustment component is located inside the wave roller and is connected to the knob.

[0008] In one embodiment, a winding bin is provided on the corrugated roller at both ends of the material holding bin, a receiving roller is rotatably arranged inside the winding bin, and a skin is wound on the receiving roller. The skin is also connected to a guide ring.

[0009] In one embodiment, the linkage includes a first rack, a second rack, and a gear; Both the first and second racks are slidably mounted on the inner wall of the isolation chamber, and the first and second racks are respectively connected to two guide rings; The gears are mounted on the inner wall of the isolation chamber and mesh with the first and second racks.

[0010] In one embodiment, the linkage further includes an adjusting ring chamber, which is coaxially slidably disposed inside the wave roller. A first rotating seat is disposed on the adjusting ring chamber corresponding to the guide ring. One end of a connecting rod is rotatably disposed on the first rotating seat, and a second rotating seat is rotatably disposed on the other end of the connecting rod. The second rotating seat is fixedly disposed on the guide ring.

[0011] In one embodiment, the adjusting component includes a lead screw, which is coaxially rotatably mounted inside the wave roller via a bracket. A nut is threaded onto the lead screw and fixedly connected to the adjusting ring chamber. The lead screw is also connected to a knob.

[0012] In one embodiment, a groove is provided around the circumference on the inner wall of the wave roller, and the adjusting ring is slidably disposed in the groove.

[0013] In one embodiment, the seeder includes a seed bin, which is fixedly mounted on the frame. A distributing roller is rotatably mounted inside the seed bin.

This achieves efficient integrated sowing and fertilization, further optimizing the corn growing environment and contributing to high and stable yields. It is easy to operate, yields significant results, and is suitable for large-scale corn planting operations. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0020] See Figures 1 to 7 As shown, the corn planter provided in this application includes: a frame 1, an engine 8 fixedly mounted on the frame 1, the output end of the engine 8 being connected to a wheel 9 via a first pulley assembly 10, the wheel 9 being mounted on the frame 1; a planter 2 is also mounted on the frame 1, the power input end of the planter 2 being connected to the output end of the engine 8 via a second pulley assembly 7, the power output end of the planter 2 being connected to a fertilizer applicator 3 via a sprocket assembly 5, the fertilizer applicator 3 being mounted on the frame 1.

[0021] Under normal operating conditions, the sprocket assembly 5 enables the seeder 2 and the fertilization mechanism 3 to work in tandem, ensuring even sowing of seeds and fertilizer and improving planting efficiency. By adjusting the fertilization mechanism 3, the amount of fertilizer can be flexibly adjusted to meet different corn planting needs, while ensuring a continuous, stable, and even distribution of fertilizer, thus maintaining balanced soil nutrients and promoting corn growth. Furthermore, when the sowing speed of the seeder 2 changes, the fertilization speed of the fertilization mechanism 3 also changes accordingly, as the seeder 2 drives the fertilization mechanism 3 via the sprocket assembly 5. This avoids fertilizer waste due to an imbalance in the seed-to-fertilizer ratio and also prevents seed burn caused by excessive fertilizer in certain areas, which could negatively impact germination rates.

[0022] The fertilization mechanism 3 includes a fertilizer bin 31, which is fixedly connected to the frame 1 via a support rod. A discharge adjustment component 33 is rotatably installed at the discharge end of the fertilizer bin 31. The power input end of the discharge adjustment component 33 is connected to the power output end of the seeder 2 via a sprocket assembly 5, and a knob 34 is installed at the other end.

[0023] The fertilization mechanism 3 also includes a scraper 32, one end of which is set on the fertilizer bin 31, and the other end is slidably abutted against the discharge adjustment component 33.

[0024] In this embodiment, the discharge rate of the discharge regulating component 33 is adjusted by adjusting knob 34 according to the corn variety, soil conditions, and planting density. This ensures that the discharge regulating component 33 and the seeder 2 work together during the corn planting process, achieving precise control of the fertilizer amount and ensuring that each seed receives appropriate nutrients, thereby improving germination rate and growth quality. Furthermore, the scraper 32 removes excess fertilizer from the discharge regulating component 33, ensuring that the discharge rate is approximately the same each time. This results in even fertilizer distribution within the same furrow and prevents the discharge regulating component 33 from becoming stuck due to excessive friction with the fertilizer and the inner wall of the fertilizer bin 31 during operation, ensuring smooth fertilizer flow.

[0025] Optionally, the discharge adjustment component 33 includes a wave roller 331, which is rotatably mounted at the discharge end of the fertilizer bin 31. Multiple isolation bins 338 are evenly arranged around the circumference of the wave roller 331, and the multiple isolation bins 338 form a material holding bin 3310 between each pair. A slide rail 3317 is provided through the side wall of the isolation bin 338, and two guide rings 339 are symmetrically slidably arranged through the slide rail 3317. A linkage component is installed inside the isolation chamber 338. One end of the linkage component is connected to the guide ring 339, and the other end is connected to the adjustment component. The adjustment component is installed inside the wave roller 331 and is connected to the knob 34.

[0026] In this embodiment, during the rotation of the wave roller 331, the fertilizer in the fertilizer bin 31 falls continuously into each of the holding bins 3310 under the influence of gravity and the vibration of the planter. The holding bins 3310 filled with fertilizer rotate sequentially to the discharge end with the wave roller 331. Under the effect of gravity and vibration, the fertilizer in the holding bins 3310 falls smoothly and is then evenly spread into the soil.

[0027] In this embodiment, the rotation of the knob 34 drives the adjustment component to rotate, which in turn drives the linkage component to control the two guide rings 339 to slide away from or towards each other along the slide rail 3317. During the sliding process of the guide rings 339, the opening size of the hopper 3310 is changed, thereby adjusting the fertilizer discharge rate.

[0028] This method adjusts the volume of fertilizer in the hopper 3310, thereby changing the fertilizer discharge rate. This ensures precise matching of fertilizer to different planting needs, avoiding waste while guaranteeing the nutrients required for corn growth and achieving efficient planting. Simultaneously, this operation ensures even discharge of fertilizer from the hopper 31, preventing localized accumulation or leakage during fertilization. It ensures that the soil around each seed absorbs nutrients evenly, thus improving overall planting results and achieving the goal of high and stable yields.

[0029] Optionally, a take-up bin 337 is provided on the corrugated roller 331 at both ends of the material storage bin 3310. A take-up roller is rotatably arranged in the take-up bin 337, and a skin is wound on the take-up roller. The skin is also connected to the guide ring 339.

[0030] In this embodiment, during the sliding process of the guide ring 339, the skin extends or contracts accordingly, precisely covering the opening of the hopper 3310, thereby changing the opening area of ​​the hopper 3310, further optimizing the fertilizer discharge, and ensuring the uniformity of fertilization.

[0031] Optionally, a torsion spring is provided at the connection between the receiving roller and the winding bin 337. The torsion spring provides stable elastic potential energy, so that the skin remains taut when the guide ring 339 slides, ensuring uniform skin coverage, improving the adjustment accuracy of the opening area of ​​the feeding bin 3310, preventing fertilizer leakage or blockage, further ensuring the smoothness and efficiency of the fertilization process, and ensuring the optimization of the corn growth environment.

[0032] Optionally, the linkage components include a first rack 3313, a second rack 3315, and a gear 3314; Both the first rack 3313 and the second rack 3315 are slidably disposed on the inner wall of the isolation chamber 338, and the first rack 3313 and the second rack 3315 are respectively connected to two guide rings 339; Gear 3314 is rotatably mounted on the inner wall of isolation chamber 338 and meshes with first rack 3313 and second rack 3315.

[0033] In this embodiment, when one of the guide rings 339 moves, the first rack 3313 drives the gear 3314 to rotate, which in turn drives the second rack 3315 to move synchronously, ensuring that the two guide rings 339 are coordinated and consistent, accurately adjusting the opening of the hopper 3310, realizing precise control of fertilizer discharge, ensuring uniform fertilization, and improving planting efficiency.

[0034] Optionally, the linkage also includes an adjusting ring chamber 335, which is coaxially slidably disposed within the wave roller 331. A first rotating seat 336 is disposed on the adjusting ring chamber 335 corresponding to the guide ring 339. One end of a connecting rod 3312 is rotatably disposed on the first rotating seat 336, and a second rotating seat is rotatably disposed on the other end of the connecting rod 3312. The second rotating seat is fixedly disposed on the guide ring 339.

[0035] The adjusting ring hopper 335 slides within the wave roller 331, and the connecting rod 3312 drives the guide ring 339 to move precisely on the guide rail 3317, thereby achieving fine adjustment of the opening area of ​​the feeding hopper 3310, realizing precise control of fertilizer discharge, ensuring uniform fertilization, improving planting efficiency, optimizing the corn growth environment, and achieving the goal of high and stable yield.

[0036] Optionally, the adjusting component includes a lead screw 333, which is coaxially rotatably mounted inside the wave roller 331 via a bracket 332. A nut 3311 is threadedly connected to the lead screw 333, and the nut 3311 is fixedly connected to the adjusting ring chamber 335. The lead screw 333 is also connected to the knob 34.

[0037] In this embodiment, rotating the knob 341 drives the lead screw 333 to rotate, which in turn drives the nut 3311 to move along the lead screw 333, causing the adjusting ring 335 to slide within the wave roller 331, precisely adjusting the position of the guide ring 339, thereby achieving precise control of the opening area of ​​the hopper 3310, ensuring uniform fertilization, improving planting efficiency, and optimizing the corn growth environment.

[0038] Optionally, a groove 334 is provided around the circumference on the inner wall of the wave roller 331, and the adjusting ring chamber 335 is slidably disposed in the groove 334. The groove 334 can effectively prevent the adjusting ring chamber 335 from shifting during the sliding process and ensure its sliding stability.

[0039] In this embodiment, the machine should be stopped when the knob 34 is turned, and the sprocket assembly 5 should be locked to prevent the wave roller 331 from rotating unexpectedly when the knob 34 is turned, which would affect the adjustment accuracy.

[0040] Optionally, the seeder 2 includes a seed bin 21, which is fixedly mounted on the frame 1. A distributing roller 23 is rotatably mounted inside the seed bin 21. The power input end of the distributing roller 23 is connected to the engine 8 through the second pulley assembly 7, and the power output end is connected to the wave roller 331 through the sprocket assembly 5. The seeder 2 also includes a plowshare, which is fixedly mounted on the frame 1. A hopper 4 is also mounted on the plowshare, and the hopper 4 is connected to the seed bin 21 and the fertilizer bin 31 respectively through the feed pipe 6.

[0041] When the feed roller 23 rotates, the seeds fall precisely into the hopper 4 through the feed pipe 6, and when the discharge adjustment component 33 rotates, the fertilizer falls precisely into the hopper 4 through the feed pipe 6 and then into the furrow of the plowshare, realizing simultaneous sowing and fertilization, ensuring that the seeds and fertilizers are evenly distributed, further improving planting efficiency, optimizing the corn growth environment, and helping to achieve the goal of high and stable yield.

[0042] In practical applications, operators need to adjust knob 34 according to soil conditions and planting needs to precisely control the opening area of ​​the hopper 3310, ensuring optimal matching between fertilizer and seeding rates. After adjusting the fertilizer discharge, the engine 8 is started, driving the distribution roller 23 and wave roller 331 to operate synchronously, ensuring that seeds and fertilizer fall evenly and consistently into the hopper 4 through the guide pipe 6, and finally to the furrow opening of the plowshare. This achieves efficient integrated sowing and fertilization, further optimizing the corn growing environment and helping to achieve high and stable yields. It is easy to operate, has significant effects, and is suitable for large-scale corn planting operations.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
