Abstract
Description
Technical Field
[0001] This application belongs to the field of crop sowing technology, and specifically relates to a no-till planter for sorghum. Background Technology
[0002] Sorghum-Sudan grass is a hybrid of sorghum and Sudan grass, possessing strong heat resistance and drought tolerance. It is adaptable to various soil types, including sandy loam, clay loam, and slightly acidic soils. Sorghum-Sudan grass is high-yielding, fast-growing, and rich in protein and sugar, making it ideal as forage for cattle and sheep. It can also be used as hay or silage. Sowing and field management of sorghum-Sudan grass must be tailored to its root system characteristics and growth rate. Due to its extensive root system and rapid growth, it requires significant nutrient uptake from the soil; therefore, land preparation and fertilization should be carried out before the first sowing to ensure sufficient organic fertilizer in the soil.
[0003] In existing technologies, sorghum seeding typically employs row sowing, where seeds are manually or using a row seeder to broadcast them along pre-drilled furrows. To improve efficiency, manual sowing often involves using hoes, shovels, or other furrow-opening devices to create shallow furrows, followed by manually scattering a handful of seeds along the furrows. This method is inefficient and results in poor seed uniformity, negatively impacting sorghum growth and distribution. While a counter-rotating no-till row seeder, as disclosed in Chinese Utility Model Patent CN219019472U, connects a tractor to a feeding mechanism, the transmission causes the feeding mechanism to sow seeds along the seed channel as the tractor moves, matching the tractor speed with the sowing speed and increasing seed density. However, because the seeds are sown in the furrows created by the rotary tiller, this seeder can cause the seeds to grow too close together, leading to uneven fertilization and potentially nutritional imbalances during growth, resulting in inconsistent growth rates or uneven seed density. Summary of the Invention
[0004] Based on the aforementioned background technology needs, this application provides a no-till planter for Sorghum sulphurica, which solves the problem that existing technologies often result in Sorghum sulphurica seeds being too close together during the sowing process, leading to uneven fertilization and potential nutritional imbalances during growth, resulting in inconsistent growth rates or uneven distribution density of Sorghum sulphurica.
[0005] To achieve the above objectives, the technical solution of this application is as follows:
[0006] A no-till planter for sorghum and dandelion includes a walking frame and a furrowing mechanism, a sowing mechanism, and a soil covering mechanism arranged sequentially on the walking frame in the opposite direction of its movement. A plurality of furrowing mechanisms are arranged in a spaced array along the width of the walking frame. The sowing mechanism includes a sowing hopper, a plurality of sowing tubes, and a seed disperser. One end of each sowing tube extends along the direction of gravity and is distributed along the movement trajectory of the furrowing mechanism, while the other end is connected to the sowing hopper. The seed disperser includes a discharge port and a plurality of distribution channels arranged in a fan shape around the discharge port. The distribution channels are distributed within the furrowing width of the furrowing mechanism, and the sowing tubes are connected to the distribution channels through the discharge port. A plurality of soil covering mechanisms are distributed along the movement trajectory of the furrowing mechanism.
[0007] Preferably, the trenching mechanism includes an extension and a trenching plow. One end of the extension is fixedly connected to the traveling frame, and the trenching plow is fixed to the end of the extension away from the traveling frame. The trenching plow includes a breaking section and a widening section. The breaking section points in the same direction as the traveling frame and is used to trench along the traveling frame's direction of movement. The widening section is located on the side of the breaking section away from the traveling frame's direction of movement and is used to increase the trenching width of the breaking section.
[0008] Preferably, the seed disperser further includes a box body, on one side of the box body having a seed outlet in a diffused shape in the opposite direction of the moving direction of the walking frame, and a plurality of material distribution plates arranged in a fan shape at intervals inside the seed outlet, with the material distribution channel formed between adjacent material distribution plates, and the discharge port being located on one side of the box body and communicating with the seed outlet through the material distribution channel.
[0009] Preferably, the seed disperser further includes a rebound plate, which is disposed inside the box and inclined relative to the discharge port, and the rebound plate forms a rebound angle with the cross-section of the discharge port.
[0010] Preferably, the rebound angle is greater than 0° and less than or equal to 45°.
[0011] Preferably, the soil covering mechanism includes a connecting rod connected to the traveling frame and a pair of soil covering plates. The pair of soil covering plates are symmetrically fixed to the end of the connecting rod away from the traveling frame and are arranged at an angle. The minimum distance between the pair of soil covering plates is less than the trenching width of the trenching mechanism.
[0012] Preferably, the sorghum no-till planter further includes a first compaction mechanism, which includes a pair of support rods arranged in the opposite direction of the movement of the walking frame and behind the soil covering mechanism, and a compaction roller rotatably disposed between the pair of support rods. The roller surface of the compaction roller is provided with a plurality of compaction patterns spaced axially, the compaction patterns are arranged in a ring around the circumference of the compaction roller, and the plurality of compaction patterns are distributed on the movement trajectory of the furrowing mechanism.
[0013] Preferably, the sorghum no-till planter further includes a second compaction mechanism, which includes a pair of swing arms disposed in the opposite direction of the movement of the walking frame and located behind the first compaction mechanism, and a soil pressing plate that can be swung between the pair of swing arms. The pair of swing arms are hinged to the walking frame.
[0014] Preferably, a reset shaft is symmetrically arranged on opposite sides of the swing arm, and the soil pressing plate is connected to the end of the reset shaft away from the swing arm. The reset shaft is used to ensure that one side plane of the soil pressing plate is always parallel to the ground.
[0015] By adopting the above technical solution, compared with the prior art, this application has at least the following beneficial effects:
[0016] The ditching mechanism breaks the soil and digs the ground as the traveling frame moves forward, forming several parallel sowing furrows on the ground. The sowing hopper dispenses seeds quantitatively and sows them into the sowing furrows through the sowing channels formed by the sowing pipe and each of the material distribution channels. Under the action of the seed disperser, the seeds can be evenly distributed in a fan shape into the sowing furrows, which not only improves the sowing efficiency, but also reduces the probability of sorghum seeds sticking together, increases the distance between seeds, and makes the seeds more evenly fertilized, which helps to improve the consistency of the growth rate and the uniformity of the distribution of sorghum seeds.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present application will be further described in detail with reference to specific embodiments.
[0027] This application discloses a no-till planter for sorghum and dandelion (hereinafter referred to as "the planter"), comprising a walking frame 10 capable of moving independently or being towed by a tractor or other driving equipment. The walking frame 10 includes at least a frame structure for mounting other equipment or devices and rollers, and the walking frame 10 can move forward on the ground by means of the rollers. The frame structure has a furrowing mechanism 20, a sowing mechanism 30, and a soil covering mechanism 40 arranged sequentially from front to back. The number of furrowing mechanisms 20 is several, and the several furrowing mechanisms 20 are arranged in an array at intervals along the width extension direction of the walking frame 10 so as to open several sowing furrows parallel to each other on the ground for sowing. The sowing mechanism 30 includes a sowing device disposed on the upper surface of the walking frame 10. The device includes a hopper 31, several seeding tubes 32, and a seed disperser 33. The seeding tubes 32 extend along the direction of gravity and their lower ends are distributed on the moving paths of each furrowing mechanism 20. The seeding hopper 31 can be the seeding hopper of a planting machine disclosed in Chinese Invention Publication No. CN119213930A. The bottom of the seeding hopper in this invention is provided with a rotating roller, and multiple seed troughs are provided on the rotating roller. Under the driving action of the drive motor that drives it, the rotating roller quantitatively outputs the seeds pre-stored in the seeding hopper through the seed troughs. (The specific internal structure of the seeding hopper 31 in this application is not a key feature for solving the technical problem of this application, so its related structure is omitted in the figure and will not be described again hereafter.) The upper end of the seeding tube 32 is connected to the seeding hopper 31, and is specifically configured to correspond to the various sub-grooves of the rotating roller inside the seeding hopper 31, so that the seeds output from the seeding hopper 31 can enter the seeding tube 32; the seed disperser 33 includes a discharge port 331 for docking with the lower end of the seeding tube 32 and several distribution channels arranged in a fan shape around the discharge port 331, and the distribution channels of any seed disperser 33 are all distributed within the opening width range of the furrowing mechanism 20. The seeding tube 32 passes through the discharge port 331. 31 is connected to the distribution channel so that the seeds entering the seed disperser 33 through the seed tube 32 can be evenly distributed in a fan shape in the seed furrow opened by the furrowing mechanism 20 under the dispersion effect of each distribution channel, thereby reducing the probability of sorghum seeds sticking together; the number of the above-mentioned soil covering mechanism 40 is also several and at least the same as the number of furrowing mechanism 20 or seed tube 32. The soil covering mechanism 40 is used to push the soil on both sides of the seed furrow into the seed furrow along the moving trajectory of the furrowing mechanism 20 during the movement process to bury the seeds.
[0028] Using the above-mentioned seeder has at least the following beneficial effects:
[0029] As the traveling frame 10 moves forward, the ditching mechanism 20 breaks the soil and opens furrows, forming several parallel sowing furrows on the ground. The sowing hopper 31 dispenses seeds quantitatively and sows them into the sowing furrows through the sowing channels formed by the sowing pipe 32 and each distribution channel. Under the action of the seed disperser 33, the seeds can be evenly distributed in a fan shape in the sowing furrows, which not only improves the sowing efficiency, but also reduces the probability of sorghum seeds sticking together and increases the distance between the seeds, making the seeds more evenly fertilized. This helps to improve the uniformity of the growth rate and the evenness of the distribution of sorghum seeds.
[0030] In addition, this application provides some more specific implementation methods to improve the above-mentioned sorghum no-till planter.
[0031] Based on the structure of the above embodiment, in order to increase the furrow width of the sowing mechanism 30 and cooperate with the seed disperser 33 to increase the seed dispersing distance, the furrowing mechanism 20 includes an extension 21 and a furrowing plow head 22. Specifically, a crossbeam is provided at the front end of the traveling frame 10 along the width extension direction. A locking structure is provided at the upper end of the extension 21, and the upper end of the extension 21 is fixed to the crossbeam by the locking structure. Its lower end extends towards the ground. The furrowing plow head 22 is fixed to the lower end of the extension 21. The furrowing mechanism 20 includes a soil-breaking part 221 and a widening part 222. The soil-breaking part 221 has a blade-like structure, and its direction is perpendicular to the traveling frame 10. The direction of 0 is consistent so that the walking frame 10 can break soil and open furrows. The widening part 222 is set on the side of the breaking part 221 away from the moving direction of the walking frame 10 and is smoothly connected to the breaking part 221. The widening part 222 has a triangular prism structure from front to back, and its width gradually increases from front to back so as to widen the sowing furrow opened by the breaking part 221 during the forward movement. In another embodiment, the breaking part 221 can also be provided with a hardened coating structure or a detachable structure at the front edge of the widening part 222 to improve the hardness of the front edge of the widening part 222 or the portability of replacement, so as to ensure that the furrowing mechanism 20 has a high furrowing efficiency.
[0032] When sowing sorghum seeds using the above-mentioned sorghum no-till seeder, the soil-breaking section 221 and the widening section 222 can increase the furrowing efficiency and furrowing width, so that the seeds can be distributed in the sowing furrow with a higher dispersion spacing after being dispersed by the seed disperser 33, further reducing the probability of the seeds sticking together.
[0033] In one embodiment, the seed disperser 33 further includes a box body 332. One side of the box body 332 is provided with a seed outlet 333 in a diffused shape in the opposite direction of the moving direction of the walking frame 10. Several distribution plates 334 are distributed in a fan shape on the inner side of the seed outlet 333. The distribution channel is formed between adjacent distribution plates 334. The discharge port 331 is located on the upper side of the box body 332 and is connected to the lower end of the sowing tube 32, so that the seeds in the sowing tube 32 can enter the box body 332 through the discharge port 331 and be dispersed and discharged from the seed outlet 333 under the action of each distribution plate 334 in the box body 332, so as to ensure that the seeds entering the sowing furrow maintain a certain distance.
[0034] Furthermore, to improve the dispersion of seeds, the seed disperser 33 also includes a rebound plate 335, which is disposed inside the housing 332 and is inclined relative to the discharge port 331, forming a rebound angle between the cross-section where the rebound plate 335 and the discharge port 331 are located.
[0035] After the seeds enter the discharge port 331 from the sowing tube 32, the seeds first bounce once through the rebound plate 335, so that the seeds enter the distribution channel with a greater degree of dispersion, thereby avoiding the crowding phenomenon caused by multiple seeds in the same distribution channel, further improving the dispersion of seeds, and reducing the speed and continuity of seeds entering the sowing furrow, and also increasing the distribution distance between the front and back of the seeds.
[0036] Furthermore, the aforementioned rebound angle is greater than 0° and less than or equal to 45° to ensure that it has a deceleration and dispersion effect on all seeds entering the discharge port 331. Within the aforementioned angle range, a preferred value is selected as the rebound angle of the rebound plate 335 to achieve the best seed dispersion effect.
[0037] In a preferred embodiment, the soil covering mechanism 40 includes a connecting rod 41 connected to the walking frame 10 and a pair of soil covering plates 42. The pair of soil covering plates 42 are symmetrically fixed to the lower end of the connecting rod 41 and are arranged at an angle, and the minimum distance between the pair of soil covering plates 42 is less than the trenching width of the trenching mechanism 20.
[0038] In this embodiment, the connecting rods 41 of each covering mechanism 40 are set at the bottom of the walking frame 10 and are respectively distributed on the moving trajectory of the ditching mechanism 20. The covering plates 42 are arranged at an angle and symmetrically, and the angle gradually increases along the moving direction of the walking frame 10. The maximum distance between each pair of covering plates 42 is greater than the ditching width of the ditching mechanism 20, and the minimum distance is less than the ditching width. This can increase the coverage area of the covering plate 42 on the sowing furrow, so as to ensure that the covering plate 42 can fully cover the sowing furrow below it, prevent the seeds from floating on the ground, and ensure that the seeds are fully fertilized and have a good environment for rooting and germination.
[0039] Based on the structure of the above embodiment, the seeder further includes a first pressing mechanism 50. The first pressing mechanism 50 includes a pair of support rods 51 arranged in the opposite direction of the moving direction of the traveling frame 10 and behind the soil covering mechanism 40, and a pressing roller 52 that can be rolled between any pair of support rods 51. The pressing roller 52 can compress and level the soil of the sowing ground during the movement of the traveling frame. In addition, the rolling surface of the pressing roller 52 is provided with a plurality of pressing grooves 521 at intervals along the axial direction. The pressing grooves 521 are circumferentially protruding from the rolling surface around the pressing roller 52, and the plurality of pressing grooves 521 are distributed on the moving trajectory of the furrowing mechanism 20 so that the sowing furrows covering the seeds are pressed with emphasis by each pressing groove 521, thereby avoiding the situation where the soil is too loose and the fertilizer evaporates and is lost too quickly, resulting in insufficient fertilization of the seeds.
[0040] Furthermore, the aforementioned seeder also includes a second compaction mechanism 60. To reduce the manufacturing cost of the seeder and simultaneously improve its land preparation effect, the second compaction mechanism 60 includes a pair of swing arms 61 arranged in the opposite direction to the movement direction of the traveling frame 10 and located after the first compaction mechanism 50, and a soil-pressing plate 62 that can be swingably arranged between the pair of swing arms 61. Specifically, the soil-pressing plate 62 can be replaced by a structure such as a steel plate or steel beam, at least with a flat bottom. The upper end of the swing arms 61 is hinged to the bottom of the traveling frame 10. During the forward movement of the traveling frame 10, the swing arms 61 drag the soil-pressing plate 62 to perform a secondary compaction of the ground after the compaction roller 52, thereby improving the overall flatness of the ground and making the soil moisture more even after irrigation.
[0041] Specifically, in order to ensure that the lower surface of the soil compaction plate 62 is always in horizontal contact with the ground, a reset shaft 63 is symmetrically provided on one side of the pair of swing arms 61. The two sides of the soil compaction plate 62 are connected to the ends of the reset shaft 63 away from the swing arms 61. Under the reset action of the reset shaft 63, the lower end of the swing arm 61 can rotate relative to the soil compaction plate 62 to filter out the deflection of the soil compaction plate 62 caused by the undulation of the ground, so that the lower surface of the soil compaction plate 62 is always parallel to the ground, so as to continuously compact and smooth the ground, and further improve the flatness of the ground.
[0042] Combining the various structures and features in the above embodiments, the above-mentioned sorghum no-till planter can improve the planting quality of sorghum.
[0043] Obviously, the above embodiments of this application are merely examples for clearly illustrating this application, and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
