Description

Technical Field

[0001] This invention relates to the field of oat seeding equipment technology, and in particular to a compound seeder for oat improvement in saline-alkali land and its land improvement method. Background Technology

[0002] Oats are an annual herbaceous plant belonging to the Poaceae family and the Avena genus. They are widely cultivated in Northeast, North, Northwest, Southwest my country, as well as Guangdong, Guangxi, and Central China. Oats prefer cool, moist, and sunny conditions and are intolerant of high temperatures. Insufficient sunlight will cause poor growth. They are generally sown in cool, dry mountainous areas, flatlands, ridges, and gentle slopes. Oats have a significant effect on lowering low-density cholesterol and also have a certain effect on raising high-density cholesterol, resulting in a very significant lipid-lowering effect. Because oats have a strong ability to resist salinity and alkali, they can grow in soils with a pH value below 9.5 and a total salt content below 4%. Their salinity-resistant properties make them an ideal crop for improving saline-alkali land. Planting oats increases surface cover and absorbs some salt ions, thereby reducing the pH value and total salt content in the soil.

[0003] Most existing oat planting equipment can only plant oats under normal conditions. When oats are planted in saline-alkali areas covered by a salt and alkali layer, traditional oat planting equipment cannot adapt to the soil environment, thus affecting the survival rate of oats after planting and having limitations in use. Summary of the Invention

[0004] This invention discloses a compound seeder for oat improvement in saline-alkali land and its land improvement method, aiming to solve the technical problem that most existing oat seeding equipment can only be used to seed oats under conventional conditions, which has limited application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A compound seeder for improving saline-alkali land with oats includes a frame, a plowshare rotatably mounted on one end of the frame, and a first motor fixedly mounted on the top of the frame and driving the plowshare. The other end of the frame is provided with a feeding mechanism for discharging soil conditioner. The feeding mechanism includes a feeding box fixed to one end of the top of the frame, and a first rotating shaft is rotatably mounted inside the feeding box.

[0007] The other end of the frame is also provided with a seeding mechanism for releasing oat seeds. The seeding mechanism includes a seeding box fixed to one end of the top of the frame. The seeding box is horizontally distributed on the side of the feeding box. A second rotating shaft is rotatably installed inside the seeding box.

[0008] The bottom of the feeding mechanism and the seeding mechanism is provided with a controlled feeding conveying mechanism. The conveying mechanism includes a base plate vertically distributed at the bottom of the seeding box, and a hydraulic rod is fixedly installed between the end of the base plate and the seeding box.

[0009] The bottom of the conveying mechanism is equipped with a tillage mechanism for digging ditches and burying seeds.

[0010] The feeding mechanism and the sowing mechanism introduce the amendment and oat seeds into the cultivation mechanism through the conveying mechanism, and the cultivation mechanism completes the digging, improvement and sowing of saline-alkali land.

[0011] By installing a feeding mechanism and a seeding mechanism on the top of the frame, pre-prepared oat seeds and amendments are introduced into the cultivation mechanism through a conveying mechanism. The frame drives the cultivation mechanism to move along the field. The cultivation mechanism digs deep ditches in the field and introduces the seeds and amendments into the ditches. The amendments surround the oat seeds, providing a favorable environment for seed growth. At the same time, the amendments can improve the saline-alkali soil of alkaline fields, ensuring the functionality of the equipment.

[0012] In a preferred embodiment, the feeding mechanism further includes a plurality of evenly distributed first material control components sleeved and fixed on the outer side of the first rotating shaft, the first material control components being distributed inside the feeding box, and a second motor being horizontally fixed on the outer side of the frame; the output end of the second motor is horizontally connected to the end of the first rotating shaft.

[0013] By installing a feed box for loading the amendment on the top of the frame, the second motor drives the first rotating shaft to rotate. The rotating first rotating shaft will synchronously drive the first material control component to rotate synchronously, thereby quantitatively conveying the amendment located inside the feed box into the tillage mechanism, ensuring the perfect operation of the equipment.

[0014] In a preferred embodiment, the seeding mechanism further includes a plurality of evenly distributed second material control components sleeved and fixed on the outer side of the second rotating shaft, the second material control components being distributed inside the seeding box.

[0015] By setting a seed box for loading oat seeds on the side of the feeding box, the rotation of the first rotating shaft synchronously drives the second rotating shaft. The rotation of the second rotating shaft synchronously drives the second material control component to rotate, thereby quantitatively conveying the oat seeds located inside the seed box into the cultivation mechanism. In conjunction with the operation of the feeding mechanism, the seeds and amendments are simultaneously discharged, thereby further ensuring the integrity of the equipment operation.

[0016] In a preferred embodiment, the conveying mechanism further includes a plurality of evenly distributed telescopic tubes that are connected through the top of the substrate and the interior of the seed box, and a plurality of evenly distributed straight tubes that are connected through the bottom of the substrate. The straight tubes and the telescopic tubes are connected through the substrate, and a rubber tube is connected through the side of each straight tube. The rubber tube is connected through the bottom of the seed box.

[0017] The system incorporates a base plate structure driven by a hydraulic rod. A tillage mechanism is mounted at the bottom of the base plate. The vertical movement of the base plate drives the tillage mechanism to move synchronously. Additionally, the top and bottom of the base plate are equipped with telescopic tubes, straight tubes, and flexible hoses. Seeds and amendments released by the feeding and seeding mechanisms can enter the tillage mechanism through these three tubes and then be released onto the field, ensuring the proper functioning of the equipment.

[0018] In a preferred embodiment, the tillage mechanism includes a plow blade fixedly installed at the bottom of each of the straight tubes. The plow blade has a through-hole for dispensing a material chamber and a seeding chamber. The material chamber is connected to the inside of the rubber tube, and the seeding chamber is connected to the inside of the straight tube. An auxiliary component is rotatably installed inside both the material chamber and the seeding chamber. The agitation of the auxiliary component assists in dispensing the seeds and amendment.

[0019] By additionally assembling a specially shaped plow blade structure at the bottom of the substrate, the vertical movement of the substrate drives the plow blade to move synchronously and insert it into the saline-alkali soil. Simultaneously, with the horizontal movement of the frame, the synchronously moving plow blade can dig deep V-shaped trenches in the saline-alkali soil. With the operation of the feeding and seeding mechanisms, the released seeds and amendments can fall into the trenches created by the plow blades through the seeding and feeding chambers inside the plow blades, respectively. On the one hand, the deep V-shaped trenches help oat seeds contact the deep, light soil of the saline-alkali soil, thereby reducing the impact of salt and alkali on the oat seeds and ensuring the germination rate of oat seeds. On the other hand, the released amendments can be laid inside the deep V-shaped trenches, isolating the oat seeds from the saline-alkali soil and maintaining the salinity of the oat seed growth environment. At the same time, the amendments that are in direct contact with the saline-alkali soil can reduce the salt and alkali content in the soil, thereby improving the soil.

[0020] In a preferred embodiment, the auxiliary component includes a spherical paddle rotatably mounted inside the feeding chamber and the seeding chamber, a pushing member distributed on the outer side of the plow blade, and a connecting rod fixedly connected between the spherical paddle and the pushing member, the connecting rod passing through the side wall of the plow blade.

[0021] By incorporating a spherical paddle structure driven by a pusher inside the plow blade, the rotational force generated by the pusher under soil friction as the plow blade moves along the soil synchronously drives the spherical paddle to rotate. The rotating spherical paddle agitates the amendment and seeds located inside the feeding and seeding chambers, thereby preventing material blockage in the feeding and seeding chambers and ensuring the proper operation of the equipment.

[0022] As can be seen from the above, the compound seeder and land improvement method for improving saline-alkali land using oats provided by the present invention have the following improvements and advantages compared with the prior art:

[0023] Firstly, by setting up a feeding mechanism and a seeding mechanism on the top of the frame, pre-prepared oat seeds and improvers are placed inside the feeding box and seeding box, respectively. A second motor drives the first rotating shaft to rotate and transmits the second rotating shaft, thereby causing the first and second material control components to rotate synchronously. The improvers and oat seeds located inside the feeding box and seeding box are quantitatively transported into the cultivation mechanism. With the additional base plate structure, the vertically moving base plate drives the cultivation mechanism to move synchronously. With the additional telescopic tubes, straight tubes and flexible tubes installed on the top and bottom of the base plate, the improvers and seeds are introduced into the deep layers of saline-alkali soil, ensuring the survival rate of oat seeds and ensuring the complete operation of the equipment.

[0024] Secondly, by additionally assembling a specially shaped plow blade structure at the bottom of the base plate, the vertical movement of the base plate drives the plow blade to move synchronously and insert into the saline-alkali soil. Accompanied by the horizontal movement of the frame, the synchronously moving plow blade can create deep V-shaped trenches in the saline-alkali soil. The seeds and amendments are then released through the seed-laying chamber and material-laying chamber inside the plow blade, respectively, falling into the trenches created by the plow blade. These deep V-shaped trenches facilitate contact between the oat seeds and the deep, slightly saline soil, reducing the impact of salt and alkali on the oat seeds and ensuring a high germination rate. Furthermore, by laying the amendment inside the deep V-shaped trenches, the oat seeds are isolated from the saline-alkali soil, maintaining the salinity of the oat seed growth environment. Simultaneously, the amendment, in direct contact with the saline-alkali soil, reduces the salt and alkali content in the soil, thus improving the soil. Unlike traditional oat planting equipment, this equipment can significantly improve the survival rate of oat seeds in saline-alkali soil. The equipment also has the function of improving the saline-alkali soil environment, possessing multi-functional and high-efficiency characteristics. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] The present invention discloses a compound seeder for improving saline-alkali land with oats and its land improvement method, which is mainly applied to the scenario of planting oats in saline-alkali land.

[0038] Reference Figures 1 to 10 A compound seeder for improving saline-alkali land with oats includes a frame 1, a plowshare 2 rotatably mounted on one end of the frame 1, and a first motor 3 fixedly mounted on the top of the frame 1 and driving the plowshare 2. The other end of the frame 1 is provided with a feeding mechanism 4 for discharging the soil conditioner. The feeding mechanism 4 includes a feeding box 401 fixed to one end of the top of the frame 1, and a first rotating shaft 402 is rotatably mounted inside the feeding box 401.

[0039] The other end of the frame 1 is also provided with a seeding mechanism 5 for releasing oat seeds. The seeding mechanism 5 includes a seeding box 501 fixed to one end of the top of the frame 1. The seeding box 501 is horizontally distributed on the side of the feeding box 401. A second rotating shaft 502 is rotatably installed inside the seeding box 501.

[0040] The bottom of the feeding mechanism 4 and the seeding mechanism 5 is provided with a conveying mechanism 6 for controlled feeding. The conveying mechanism 6 includes a base plate 601 vertically distributed at the bottom of the seeding box 501. A hydraulic rod 602 is fixedly installed between the end of the base plate 601 and the seeding box 501.

[0041] The bottom of the conveying mechanism 6 is equipped with a ditch-opening and seed-burying tillage mechanism 7;

[0042] The feeding mechanism 4 and the sowing mechanism 5 introduce the amendment and oat seeds into the cultivation mechanism 7 through the conveying mechanism 6, and complete the digging, improvement and sowing of saline-alkali land through the cultivation mechanism 7.

[0043] In this embodiment: the operator fills the soil conditioner into the feeding mechanism 4 and the oat seeds into the sowing mechanism 5. Then, the frame 1 is loaded onto an external mobile platform, which moves the frame 1 to the saline-alkali field. The platform then moves the frame 1 along the field. At the same time, the first motor 3 is started, which drives the plowshare 2 to rotate. As the frame 1 moves, the saline-alkali layer on the surface of the field is broken up. While the frame 1 moves, the synchronously started conveying mechanism 6 lowers the tillage mechanism 7, inserts it vertically into the saline-alkali land, and opens ditches. The synchronously started feeding mechanism 4 and sowing mechanism 5 can quantitatively sow oat seeds and conditioner into the ditches opened by the tillage mechanism 7, completing the oat planting and saline-alkali land improvement.

[0044] In the above scheme, considering the need to provide a favorable environment for the growth of oat seeds, the specific operations are as follows.

[0045] Reference Figures 1 to 5In a preferred embodiment, the feeding mechanism 4 further includes a plurality of evenly distributed first material control components 403 sleeved and fixed on the outer side of the first rotating shaft 402. The first material control components 403 are distributed inside the feeding box 401. A second motor 404 is horizontally fixed on the outer side of the frame 1. The output end of the second motor 404 is horizontally connected to the end of the first rotating shaft 402.

[0046] In this embodiment: while the frame 1 moves, the second motor 404 starts synchronously and drives the first rotating shaft 402 to rotate. The rotating first rotating shaft 402 will synchronously drive the first material control component 403 to rotate. The rotating first material control component 403 will slowly carry the modifier accumulated on the surface out from the inside of the feeding box 401 and put it down.

[0047] In the above scheme, considering the need to quantitatively sow oat seeds, the specific operation is as follows.

[0048] Reference Figures 1 to 5 In a preferred embodiment, the seeding mechanism 5 further includes a plurality of evenly distributed second material control elements 503 sleeved and fixed on the outer side of the second rotating shaft 502, the second material control elements 503 being distributed inside the seeding box 501.

[0049] In this embodiment: when the first rotating shaft 402 rotates, it will simultaneously drive the second rotating shaft 502 to rotate. The rotating second rotating shaft 502 will simultaneously drive the second material control component 503 to rotate. The rotating second material control component 503 will slowly carry the oat seeds accumulated on the surface out of the seed box 501 and put them down. A belt 504 is connected between the ends of the first rotating shaft 402 and the second rotating shaft 502.

[0050] Furthermore, it should be noted that: both the feeding box 401 and the seed box 501 are fixedly installed with several partitions 8, which divide the feeding box 401 into several compartments. The first material control component 403 is evenly distributed inside each compartment. The partitions 8 divide the seed box 501 into several compartments, and the second material control component 503 is evenly distributed inside each compartment.

[0051] In the above scheme, considering the need to deliver oat seeds and amendments to the soil, the specific operation is as follows.

[0052] Reference Figures 1 to 2 , Figures 4 to 8In a preferred embodiment, the conveying mechanism 6 further includes a plurality of evenly distributed telescopic tubes 603 that are connected through the top of the substrate 601 and the interior of the seed box 501, and a plurality of evenly distributed straight tubes 604 that are connected through the bottom of the substrate 601. The straight tubes 604 and the telescopic tubes 603 are connected through the tubes. Each straight tube 604 has a rubber tube 605 that is connected through the side, and the rubber tube 605 is connected through the bottom of the feeding box 401.

[0053] In this embodiment: the modifier released from the feed box 401 enters the inside of the hose 605 and then enters the inside of the tillage mechanism 7 through the hose 605. Meanwhile, the oat seeds released from the seed box 501 enter the inside of the telescopic tube 603 and the straight tube 604 and then enter the inside of the tillage mechanism 7 through the telescopic tube 603 and the straight tube 604. At the same time, as the frame 1 moves along the saline-alkali land, the hydraulic rod 602 is activated synchronously, extending outward and pushing the base plate 601 down. The descending base plate 601 synchronously drives the tillage mechanism 7, causing the tillage mechanism 7 to be inserted into the saline-alkali land.

[0054] In the above scheme, considering the application of the improver and oat seeds, the specific operation is as follows.

[0055] Reference Figures 1 to 2 , Figures 4 to 5 , Figures 7 to 9 In a preferred embodiment, the tillage mechanism 7 includes a plow blade 701 fixedly installed at the bottom of each straight tube 604. The plow blade 701 has a feeding chamber 702 and a seeding chamber 703 that are connected through it. The feeding chamber 702 is connected through to the inside of the rubber tube 605, and the seeding chamber 703 is connected through to the inside of the straight tube 604. An auxiliary component 704 is rotatably installed inside both the feeding chamber 702 and the seeding chamber 703. The agitation of the auxiliary component 704 assists in feeding the seeds and improver.

[0056] In this embodiment: the modifier released from the feeding box 401 enters the inside of the hose 605 and then enters the inside of the plow blade 701 through the hose 605. Meanwhile, the oat seeds released from the seed box 501 enter the telescopic tube 603 and the straight tube 604 and then enter the inside of the plow blade 701 through the telescopic tube 603 and the straight tube 604. The modifier inside the plow blade 701 falls out through the feeding chamber 702, and the seeds inside the plow blade 701 fall out through the seeding chamber 703. As the frame 1 moves along the saline-alkali land, the hydraulic rod 602 is activated synchronously, extending outwards and pushing the substrate 601 downwards. The descending substrate 601... 1. Simultaneously, the plow blade 701 is driven, causing it to insert into the saline-alkali soil and create a deep V-shaped trench. The soil conditioner and seeds that fall out will be laid inside the deep V-shaped trench, completing the sowing of oats. Each plow blade 701 has an arc-shaped component 705 fixedly installed at its bottom. The arc-shaped component 705 is distributed on the side of the outlet end of the feeding chamber 702. As the plow blade 701 moves, the arc-shaped component 705 will squeeze the soil conditioner located inside the deep V-shaped trench, compacting the soil conditioner and wrapping it around the outside of the oat seeds. The soil conditioner located on the outside of the seeds can block salt molecules in the soil around the seeds, improving the seed development effect.

[0057] In the above scheme, considering the need to prevent the improver and oat seeds from clogging the inside of the plow blade 701, the specific operation is as follows.

[0058] Reference Figures 7 to 9 In a preferred embodiment, the auxiliary component 704 includes a spherical paddle 7041 rotatably mounted inside the feeding chamber 702 and the seeding chamber 703, a pusher 7042 distributed on the outer side of the plow blade 701, and a connecting rod 7043 fixedly connected between the spherical paddle 7041 and the pusher 7042, the connecting rod 7043 penetrating through the side wall of the plow blade 701.

[0059] In this embodiment: As the plow blade 701 moves along the saline-alkali land, the pusher 7042 located outside the plow blade 701 will be squeezed by the soil and rotate. At the same time, the rotating blade will drive the spherical paddle 7041 to rotate synchronously through the connecting rod 7043. The rotating spherical paddle 7041 will agitate the amendment located inside the feeding chamber 702 and the seeds located inside the seeding chamber 703, thereby assisting in the release of the amendment and seeds.

[0060] Working principle: During use, the operator fills the feed hopper 401 with the soil conditioner and the seed hopper 501 with oat seeds. Then, the frame 1 is mounted on an external mobile platform. The platform moves the frame 1 to the saline-alkali field. Simultaneously, the platform moves the frame 1 along the field, and the first motor 3 is activated. The rotating first motor 3 drives the plowshare 2 to rotate, breaking up the saline-alkali layer on the field surface as the frame 1 moves. While the frame 1 moves, the second motor 40... 4. Synchronously start and drive the first rotating shaft 402 to rotate. The rotating first rotating shaft 402 will synchronously drive the first material control component 403 to rotate. The rotating first material control component 403 will slowly carry the modifier accumulated on the surface out from the inside of the feeding box 401 and put it down. At the same time as the first rotating shaft 402 rotates, it will synchronously drive the second rotating shaft 502 to rotate. The rotating second rotating shaft 502 will synchronously drive the second material control component 503 to rotate. The rotating second material control component 503 will slowly carry the modifier accumulated on the surface out from the inside of the feeding box 401 and put it down. Oat seeds are carried out and lowered from inside the seed box 501. The improver lowered from inside the feeding box 401 enters the rubber tube 605 and then through the tube into the plow blade 701. The oat seeds lowered from inside the seed box 501 enter the telescopic tube 603 and the straight tube 604, and then through these tubes into the plow blade 701. The improver inside the plow blade 701 falls out through the feeding chamber 702, and the seeds inside the plow blade 701 are then released through the seed box. The cavity 703 is released, in which the soil conditioner is first added, followed by the seeds. The soil conditioner can block salt molecules in the soil, improving the seed development effect. As the frame 1 moves along the saline-alkali land, the hydraulic rod 602 will be activated simultaneously, extending outward and pushing the base plate 601 to descend. The descending base plate 601 will simultaneously drive the plow blade 701, causing the plow blade 701 to insert into the saline-alkali land and open a deep V-shaped trench. The released soil conditioner and seeds will be laid inside the deep V-shaped trench, completing the sowing of oats.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The partitions (8) divide the feeding box (401) into several compartments. The first material control component (403) is evenly distributed inside each compartment. The partitions (8) divide the seed box (501) into several compartments. The second material control component (503) is evenly distributed inside each compartment.

7. The land improvement method for oat-based saline-alkali land using a compound seeder according to claim 1, characterized in that, Includes the following steps; S1: The operator fills the improver into the inside of the feeding mechanism (4) and the oat seeds into the inside of the sowing mechanism (5); S2: The frame (1) is mounted on an external mobile platform, and the frame (1) is moved to the saline-alkali field by the platform; S3: Control the platform to drive the frame (1) to move along the field. While moving, start the first motor (3) to drive the plowshare (2) to rotate and break up the saline-alkali layer on the surface of the field. S4: As the vehicle frame (1) moves, the synchronously activated conveying mechanism (6) will drive the tillage mechanism (7) to descend, thus opening channels in the saline-alkali land. S5: As the frame (1) moves, the feeding mechanism (4) and the seeding mechanism (5) start synchronously and can quantitatively sow oat seeds and amendments into the ditches opened by the tillage mechanism (7) to complete oat planting and saline-alkali land improvement. S6: The modifier placed inside the feeding mechanism (4) is made of sand, slag and organic fertilizer.
