Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and particularly relates to a no-till reseeder for gentle slopes. Background Art

[0002] A no-till reseeder is an agricultural mechanical equipment that directly performs seeding operations on the stubble land without traditional plowing. The principle is to use a special furrow opener to create a seed furrow in the unplowed soil, sow the seeds into the furrow, and then perform a series of operations such as covering the soil and rolling to complete the seeding process.

[0003] No-till seeders are mainly used in plain areas, which can complete large-area seeding operations at one time, giving full play to their advantages of high operation efficiency and good seeding quality. Moreover, the seeding uniformity is high, which is conducive to the large-scale and standardized planting of crops. In addition, existing no-till seeders usually have a certain slope adaptability in design, such as using a low center of gravity, wide tires or crawlers, and a flexible suspension system. By adjusting the angle and height of the working parts with the ground, they can operate stably in gentle slope hilly areas.

[0004] In some areas, the amount of straw and weeds remaining after crop harvest is large and unevenly distributed. When a no-till reseeder operates, the furrow opener is likely to come into contact with and entangle the straw and weeds. The entangled straw and weeds will form a blockage around the furrow opener, hindering the normal flow and discharge of the soil. This situation not only causes the furrow to deform but also makes the soil accumulate in front of the furrow opener, resulting in soil heaping. This increases the furrowing resistance and makes it difficult to evenly cover the soil after seeding, affecting the growth of the seeds. In addition, due to the difference in soil texture, the soil in some areas will crack when the humidity and temperature change. When seeding, the seeds are likely to fall into the deep gaps, resulting in uneven depths of the seeds in the soil, affecting the subsequent germination and growth uniformity, and even making it difficult for the seeds to emerge from the soil and causing rotten seeds. Summary of the Invention

[0005] The purpose of the present invention is to propose a no-till reseeder for gentle slopes to solve the problems that the furrow opener is easily in contact with and entangled by straw and weeds, hindering the normal flow and discharge of the soil, resulting in furrow deformation and soil heaping, and that the soil in some areas will crack when the humidity and temperature change, causing uneven depths of the seeds in the soil.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A no-till reseeder for gentle slopes includes a frame body, and a hopper and a furrow opener are fixedly installed at the top and bottom of the frame body respectively. It also includes:

[0007] Truncating mechanism, the truncating mechanism includes a ridge plate fixed to the tip of the furrow opener, an installation plate is slidably connected to the outer side of the ridge plate, a spring is provided between the installation plate and the ridge plate, and knife heads arranged at equal intervals are fixedly connected to the outer sides of both the ridge plate and the installation plate;

[0009] Soil covering assembly, the soil covering assembly includes a soil deflecting plate arranged on the outer side of the furrow opener;

[0010] When the furrow opener is opening a furrow, the two groups of knife heads continuously cross and cut the straw and weeds wound around the outer side of the ridge plate. At the same time, the compaction wheel rolls in the furrow to compact the soil conveyed to the furrow by the conveying wheel.

[0014] As a further description of the no-till seeder for gentle slopes of the above technology: a support rod for supporting the connecting rod is fixedly connected inside the ridge plate, the fulcrum of the connecting rod is biased towards the hammer direction, and under the action of gravity, one end of the connecting rod close to the hammer tilts up.

[0015] As a further description of the no-till seeder for gentle slopes of the above technology: a back plate is fixedly connected to one side of the furrow opener, a mud guard and a partition that wraps the rotating wheel are fixedly connected inside the furrow opener, and a housing that wraps the conveying wheel is fixedly connected to one side of the mud guard.

[0016] As a further description of the no-till seeder for gentle slopes of the above technology: a scraper that fits the edge of the compaction wheel is fixedly connected inside the furrow opener, and when the compaction wheel rolls, the scraper scrapes off the soil adhering to the edge of the compaction wheel.

[0017] Further description of a no-till reseeding machine for gentle slopes as the above-mentioned technology: It further includes a pressing and consolidating unit. The pressing and consolidating unit includes a convex block fixed on one side of the driving wheel. A push rod is slidably connected inside the fender. One side of the fender is fixedly connected with a diversion plate. One end of the push rod is fixedly connected with a limiting frame sleeved outside the convex block, and the other end penetrates through the diversion plate and is fixedly connected with a pressing plate.

[0018] Further description of a no-till reseeding machine for gentle slopes as the above-mentioned technology: Two mutually meshing half gears are rotatably connected to the top of the furrow opener. One side of the half gear is fixedly connected with a mounting frame for fixedly installing a soil-scraping plate. Crushing nails are arranged inside the soil-scraping plate.

[0019] Further description of a no-till reseeding machine for gentle slopes as the above-mentioned technology: It further includes an auxiliary conveying component. The auxiliary conveying component includes a sleeve fixed on one side of the back plate. One side of the sleeve is fixedly connected with an elastic sheet. The top end of the elastic sheet is fixedly connected with a convex plate.

[0020] In summary, due to adopting the above-mentioned technology of a no-till reseeding machine for gentle slopes, the beneficial effects of the present invention are as follows:

[0021] When the no-till reseeding machine opens a furrow through the furrow opener, the two groups of cutter heads continuously intersect, which can cut off the straw and entangled weeds blocking in front during the forward movement of the furrow opener, reduce the resistance during the forward movement of the furrow opener, and avoid the obstruction of soil flow. Thus, during the furrow opening process, the soil can be guided by the furrow opener to flow smoothly to both sides and separate, forming a stable-shaped furrow, providing a good bedding environment for the seeds, enabling the seeds to be evenly distributed at the bottom of the furrow, improving the germination rate and germination uniformity of the seeds. And at the same time of furrow opening, the compaction wheel can compact the soil conveyed by the conveying wheel into the furrow opener at the bottom of the furrow. Through this part of the soil, the cracks existing on the ground are filled. When the device sows in the area where the ground cracks, the seeds will not fall into the cracks on the ground after furrow opening, ensuring the unified sowing depth of the seeds, further improving the germination and growth uniformity of the seeds, and avoiding the situation that the seeds are difficult to emerge or even rot due to being too deep.

[0022] The soil turned out during furrow opening can be pulverized and diverted through the soil-scraping plate and the crushing nails, so that the soil is dispersed and filled in the sown positions, realizing automatic soil covering. Compared with the existing device that covers the soil by dragging a long scraping plate, this design can cover the soil independently for each furrow, improving the uniformity of soil covering, being beneficial to the seeds to absorb water and germinate synchronously, improving the germination uniformity of the seeds, and the crushing nails pulverize the flowing soil, improving the air permeability of the soil, which helps to improve the germination rate of the seeds.

[0023] The preliminary compaction of the soil can be carried out by the compaction unit before the soil slides to the bottom of the trench. After the loose soil is compacted, it becomes firm. When it slides to the bottom of the trench, it will be laid on the bottom of the trench to cover the gaps and will not enter the gaps. Thus, after the compaction roller compresses, the gaps will be covered. This design can avoid the situation where loose soil enters the gaps after sliding to the bottom of the trench but cannot completely fill the too-deep gaps, and then further ensures the uniformity of the sowing depth of the seeds;

[0024] During the process of the conveying wheel rotating to convey the soil, it is continuously struck by the hammers. This not only makes the soil distribution inside the cavity more uniform when the conveying wheel conveys the soil, improving the uniformity of soil conveyance, but also avoids the soil sticking in the cavity and causing blockage. At the same time, the position where the hammers strike is above the inclined conveying wheel, which enables the conveying wheel to convey the soil between the mudguard and the furrow opener. After that, the soil can slide out of the cavity under vibration, avoiding the situation where the soil fails to slide out in time and the conveying wheel continues to rotate and takes the soil out, thereby ensuring the continuity of soil conveyance;

[0025] Due to the characteristics of the seeds such as size, shape, and fluidity, in some cases, the seeds will be blocked in the hose. While the conveying wheel conveys the soil, it frequently squeezes the convex plate, causing the elastic piece to deform and press the conveying hose passing through the sleeve, which can effectively change the spatial state inside the hose and the flow conditions of the seeds. Through the dynamic pressing action, it prevents the seeds from stagnating, accumulating, or sticking to each other in the hose, thereby avoiding the blockage of the seeds in the hose and ensuring that the seeds can continuously and smoothly pass through the conveying hose, providing a stable and reliable seed supply for the sowing operation.

[0043] Next, the technical solution of a no-till seeding machine for gentle slopes of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] As Figures 1 - 10 shown, a no-till seeding machine for gentle slopes provided by the present invention includes a frame 10. A silo 11 and a furrow opener 12 are respectively fixedly installed at the top and bottom of the frame 10. A plurality of furrow openers 12 are arranged at equal intervals. By dragging the frame 10 with an external driving device, a plurality of furrow openers 12 can be driven to open furrows in batches, and at the same time, the seeds in the silo 11 are conveyed to the furrows through a hose, realizing no-till seeding. It further includes:

[0045] The cutting mechanism 20 includes a ridge plate 21 fixed to the tip of the furrow opener 12. A mounting plate 23 is slidably connected to the outer side of the ridge plate 21. A spring 25 is provided between the mounting plate 23 and the ridge plate 21. Knife heads 26 arranged at equal intervals are fixedly connected to the outer sides of both the ridge plate 21 and the mounting plate 23. Two groups of knife heads 26 are arranged in parallel, and the cutting edges are located in a plane. When the two groups of knife heads 26 are staggered, the straws and weeds caught between the knife heads 26 are cut off. The outer end of each knife head 26 is conical, which is convenient for straws and weeds to enter between the knife heads 26;

[0046] The filling mechanism 30 includes a conveying wheel 31, a transmission wheel 32, and a compaction wheel 33 that are sequentially rotatably connected inside the furrow opener 12 from top to bottom. Cavities that are inclined and arranged in a circumferential array around the center point of the conveying wheel 31 are formed on both sides of the conveying wheel 31. When the conveying wheel 31 rotates, the cavities are used to store soil and the soil is conveyed by rotation. A vibration assembly 39 is arranged inside the furrow opener 12;

[0047] The soil covering assembly 50 includes soil deflecting plates 53 arranged on the outer side of the furrow opener 12. The two soil deflecting plates 53 are inclined and symmetrically arranged. During the movement of the soil deflecting plates 53, the soil turned to the ground by the furrow opener 12 is pushed and diverted, so that the soil dug out by the furrow can be gathered and recycled into the trench again after sowing to complete soil covering;

[0048] When the furrow opener 12 is opening a furrow, the two groups of knife heads 26 continuously stagger to cut off the straws and weeds wound around the outer side of the ridge plate 21. At the same time, the compaction wheel 33 rolls in the trench to compact the soil conveyed to the trench by the conveying wheel 31.

[0049] Refer to Figure 8 and Figure 9The inner rotation of the ridge plate 21 is connected to a rotating wheel 22 in contact with the conveying wheel 31. The rotating wheel 22 and one side of the mounting plate 23 are both provided with convex teeth 24, and the convex teeth 24 mesh with each other. The outer periphery of the rotating wheel 22 has an annular groove. The convex teeth 24 on the mounting plate 23 enter the annular groove of the rotating wheel 22 and engage with the convex teeth 24 fixed on the rotating wheel 22. The purpose of this design is to enable the rotating wheel 22 to contact and transmit with the conveying wheel 31 at the same time. When the furrow opener 12 moves forward, the compacting wheel 33 rolls on the ground and rotates clockwise, driving the transmission wheel 32 to rotate counterclockwise. Therefore, the conveying wheel 31 rotates clockwise and the rotating wheel 22 rotates counterclockwise. , so that the rotating wheel 22 rotates counterclockwise to push the mounting plate 23 upward through the convex teeth 24. At this time, the spring 25 is stretched. After the two sets of convex teeth 24 are staggered, the contraction elastic force of the spring 25 drives the mounting plate 23 to drop and reset, thereby realizing the reciprocating motion of the mounting plate 23, so that one set of cutter heads 26 on the mounting plate 23 is continuously staggered with the other set of cutter heads 26 to achieve a shearing effect. Both ends of the mounting plate 23 are fixedly connected with a shield plate 27. When the mounting plate 23 slides in the ridge plate 21, the shield plate 27 blocks the gap between the ridge plate 21 and the mounting plate 23 to prevent soil from entering between the mounting plate 23 and the ridge plate 21 and hindering the movement of the mounting plate 23.

[0050] The vibration assembly 39 includes a connecting rod 392 rotatably connected to one side of the spine plate 21, one end of the connecting rod 392 is fixedly connected to a hammer 391 and the other end extends to the top of the mounting plate 23, the interior of the spine plate 21 is fixedly connected to a support rod 393 for supporting the connecting rod 392, the fulcrum of the connecting rod 392 is biased toward the direction of the hammer 391, and under the action of gravity, the end of the connecting rod 392 close to the hammer 391 is tilted, and at this time, the support of the support rod 393 is used to limit the distance that the connecting rod 392 close to one end of the mounting plate 23 descends, so that one end of the connecting rod 392 is always located on the movement trajectory of the mounting plate 23, and when the mounting plate 23 moves, it can hit the connecting rod 392 to deflect it and drive the hammer 391 to hit the conveying wheel 31, so that the soil in the cavity of the conveying wheel 31 slides out under vibration.

[0051] Reference Figure 6 and Figure 7, a back plate 38 is fixedly connected to one side of the furrow opener 12. One side of the conveying wheel 31 penetrates through the back plate 38. The side of the back plate 38 away from the furrow opener 12 is conical. Therefore, during the clockwise rotation of the conveying wheel 31, the position where the back plate 38 is penetrated by the conveying wheel 31 can scrape the soil attached to the edge of the conveying wheel 31 to both sides, causing the soil to fall into the cavity of the conveying wheel 31, enabling the conveying wheel 31 to fully contact the rotating wheel 22 while also fully exerting the effect of the conveying wheel 31 in conveying soil. To prevent the soil in the cavity of the conveying wheel 31 from falling out and adhering to other parts during the rotation of the conveying wheel 31, a mudguard 35 and a partition plate 34 that wraps the rotating wheel 22 are fixedly connected inside the furrow opener 12. One side of the mudguard 35 is fixedly connected to a housing 37 that wraps around the outside of the conveying wheel 31. Therefore, the soil in the cavity of the conveying wheel 31 can only be conveyed to the space between the mudguard 35 and the furrow opener 12. A scraping plate 36 that fits the edge of the compaction wheel 33 is fixedly connected inside the furrow opener 12, and the bottom end of the back plate 38 contacts the edge of the compaction wheel 33. When the compaction wheel 33 rolls clockwise, both the scraping plate 36 and the back plate 38 can scrape the soil attached to the edge of the compaction wheel 33, enabling the compaction wheel 33 to fully exert its compaction effect.

[0052] It further includes a compaction unit 40. The compaction unit 40 includes a convex block 41 fixed to one side of the transmission wheel 32. A push rod 43 is slidably connected inside the mudguard 35. One side of the mudguard 35 is fixedly connected to a diversion plate 45 for diverting the soil conveyed by the conveying wheel 31 to prevent the soil from accumulating between the compaction wheel 33 and the inner wall of the furrow opener 12. One end of the push rod 43 is fixedly connected to a limit frame 42 sleeved outside the convex block 41, and the other end penetrates through the diversion plate 45 and is fixedly connected to a pressing plate 44. When the transmission wheel 32 rotates, it drives the convex block 41 to perform a circular motion, causing the limit frame 42 to reciprocate horizontally, and then driving the pressing plate 44 through the push rod 43 to extrude the soil passing between the diversion plate 45 and the ridge plate 21, making the loose soil compact. When the soil falls to the bottom of the trench, it will not enter the gaps due to looseness, but will be laid on the bottom of the trench to cover the gaps, thus preventing the seeds from falling into the deep gaps during sowing. At the same time, the continuous movement of the pressing plate 44 can also prevent the soil from clogging between the furrow opener 12 and the mudguard 35, helping the soil to flow smoothly.

[0053] Refer to Figure 3, in order to facilitate the synchronous adjustment of the angle of the soil pushing plate 53, two meshing half gears 51 are rotatably connected to the top of the furrow opener 12. One side of the half gear 51 is fixedly connected with a mounting bracket 52 for fixedly installing the soil pushing plate 53. By adjusting the angle of one soil pushing plate 53, the angle of the other soil pushing plate 53 can be adjusted in the same size through the transmission of the mounting bracket 52 and the half gear 51. This design can facilitate the angle adjustment of the soil pushing plate 53 and make the two soil pushing plates 53 always in a symmetrical state, so that the diversion effects of the two soil pushing plates 53 are the same, avoiding uneven soil covering during the furrowing process. The height at which the soil pushing plate 53 is fixed to the mounting bracket 52 can be adjusted by bolts, so that the soil pushing plate 53 is suitable for different furrowing depths of the furrow opener 12. In order to facilitate the conveying wheel 31 to convey soil, crushing nails 54 are provided on the inner side of the soil pushing plate 53. When the soil pushing plate 53 diverts the soil, the consolidated soil will be fully crushed under the extrusion of the crushing nails 54, and the air permeability of the soil can be increased after being crushed, which helps the seeds to germinate and grow.

[0054] Refer to Figure 4 and Figure 5 , it further includes an auxiliary conveying component 60. The auxiliary conveying component 60 includes a sleeve 61 fixed to one side of the back plate 38. One side of the sleeve 61 is fixedly connected with a spring piece 62. The top of the spring piece 62 is fixedly connected with a convex plate 63. During sowing, the hose for conveying seeds at the bottom of the hopper 11 is inserted into the sleeve 61. While the conveying wheel 31 conveys the soil, the convex plate 63 is extruded by the inner wall of the cavity, causing the spring piece 62 to deform and press the hose, effectively changing the spatial state inside the hose and the flow conditions of the seeds, preventing the seeds from stagnating, accumulating or adhering to each other in the hose and causing blockage.

[0055] Working principle: Insert and fix the hose for conveying seeds on the hopper 11 into the sleeve 61, and then fix the frame 10 to an external driving device. Use the external power to drag the frame 10 to move on the cultivated land, so that the furrow opener 12 inserted into the ground moves on the cultivated land to open furrows. While opening the furrows, control the seed conveying to achieve no-till seeding;

[0056] During the process of the furrow opener 12 moving to open furrows, it drives the compaction wheel 33 to roll in the furrow, and at the same time drives the half gear 51, the mounting bracket 52 and the soil pushing plate 53 to move, so that the soil pushing plate 53 pushes the soil turned out by the furrowing, and the soil on both sides of the furrow is gathered and pushed into the furrow after sowing to achieve automatic soil covering;

[0057] During the soil covering process, the soil will pass between the soil deflecting plate 53 and the furrow opener 12. Some of the soil contacts the conveying wheel 31 and enters the cavity of the conveying wheel 31. The compaction wheel 33 rolls on the ground and rotates clockwise, driving the transmission wheel 32 to rotate counterclockwise, so that the conveying wheel 31 rotates clockwise to convey the soil in the cavity to the space between the fender 35 and the furrow opener 12. At the same time, the conveying wheel 31 drives the rotating wheel 22 to rotate counterclockwise, and pushes the mounting plate 23 upward through the convex teeth 24. At this time, the spring 25 is stretched. After the two groups of convex teeth 24 are staggered, the contraction elastic force of the spring 25 drives the mounting plate 23 to descend and reset. The reciprocating movement of the mounting plate 23 drives one set of cutter heads 26 and the other set of cutter heads 26 to continuously stagger, achieving the shearing effect. And when the mounting plate 23 moves upward, it will push one end of the connecting rod 392, causing the connecting rod 392 to deflect and drive the hammer 391 to strike the conveying wheel 31, and the soil inside the cavity of the conveying wheel 31 slides down due to the knocking vibration;

[0058] The rotation of the transmission wheel 32 drives the convex block 41 to do circular motion, driving the limit frame 42 to reciprocate horizontally, and then driving the pressing plate 44 to press the soil passing between the diversion plate 45 and the ridge plate 21 through the push rod 43, making the loose soil compact, so that when the soil falls to the bottom of the ditch, it is laid on the bottom of the ditch to cover the gap, thus preventing seeds from falling into the deep gap during sowing;

[0059] While conveying the soil, the conveying wheel 31 presses the convex plate 63 through the inner wall of the cavity, causing the elastic piece 62 to deform and press the hose for conveying seeds, preventing the seeds from stagnating, accumulating or adhering to each other in the hose and causing blockage.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
