Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seeding equipment, and specifically to a multi-scenario assisted precision seeder. Background Art

[0002] In modern agricultural production, seeders, as important agricultural machinery and equipment, play a key role in improving seeding efficiency and ensuring crop yields. Currently, most of the seeders widely used in the market are designed and developed based on the cultivated land environment with large areas, flat terrain, and uniform soil moisture. Such seeders can achieve efficient and precise seeding operations under ideal cultivated land conditions, greatly promoting the large-scale and modernization process of agricultural production.

[0003] However, when it comes to uneven terrain, it has a certain impact on the applicability of existing seeders. For example, the terrain in Yunnan Province is composed of basins, river valleys, hills, low mountains, middle mountains, high mountains, mountain plateaus, and plateaus, which are distributed alternately and are very complex. The cultivated land in mountainous areas is rugged and uneven, with large slope changes. In such scenarios, existing seeders suitable for flat land are difficult to maintain a stable working posture, and the seed metering device cannot accurately control the amount of seeds falling due to the shaking of the machine body, resulting in uneven seeding density. At the same time, due to the limited flat land area, after natural rain or irrigation in mountainous cultivated land, the soil moisture content in the field is relatively high, and the land is wet and sticky. For example, in some mountain valleys, the soil quickly becomes muddy after rainfall. When existing ditching plows operate in wet and sticky soil, it is extremely easy to have the situation of clay clogging, making it difficult to open ditches, which in turn affects the seeding progress and quality. Moreover, large and medium-sized agricultural machinery is restricted by complex terrain and is difficult to operate flexibly in mountainous areas. Although small agricultural machinery is relatively flexible, existing small seeders cannot effectively solve the problem of difficult seeding in the face of such special terrain and soil conditions, seriously restricting the development of agricultural mechanization in mountainous areas of Yunnan Province. Therefore, the present invention provides a multi-scenario assisted precision seeder to solve the deficiencies existing in the prior art. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-scenario assisted precision seeder, which solves the problem that existing seeders have poor adaptability for seeding in areas with complex terrain where there are few plains and many mountains.

One end of the transmission rod is fixedly connected to the rotating shaft of a group of tires. A limiting ring is fixedly connected to the bottom of one of the outer edge brackets. A hanging rod is fixedly connected to the top of the power box. The outside of the hanging rod is slidably connected to the inside of the limiting ring.

[0007] Preferably, a rotating rod is rotatably connected to the inside of the two seeding boxes. Pulley wheels are sleeved on the outside of the rotating rod and the outside of the transmission rod. Cams are fixedly connected to both ends of the rotating rod.

[0008] Preferably, two watering mechanisms are arranged outside the central bracket. The watering mechanisms include a water tank and a water tank. The water tank and the water tank are respectively arranged at the top and bottom of the central bracket. A conduit is fixedly connected between the water tank and the water tank.

[0009] Preferably, a water outlet pipe is fixedly connected to one end of the water tank, and a nozzle is installed at one end of the water outlet pipe. A spring movable rod is slidably connected to the through hole inside the water tank. A piston is fixedly connected to one end of the spring movable rod. The other end of the spring movable rod is in contact with the outside of the cam.

[0010] Preferably, two damping shock absorbers are installed at the bottom of the outer edge bracket. Screws are arranged outside the damping shock absorbers. The bottom end of the damping shock absorber is rotatably connected to a group of tires. The number of each group of tires is two.

[0011] Preferably, two connecting rods are rotatably connected to the bottom of the central bracket. One end of the connecting rod is rotatably connected to the outside of the L-shaped rod. A limiting frame is fixedly connected to the outside of the central bracket. The outside of the L-shaped rod is slidably connected to the inside of the limiting frame. A guiding rod is fixedly connected to the bottom of the central bracket. One end of the L-shaped rod is sleeved on the outside of the guiding rod.

[0012] Preferably, a ditch plow is fixedly connected to the bottom of the L-shaped rod, and a vibration cylinder is installed outside the ditch plow.

[0013] Preferably, a mounting post is fixedly connected to the bottom of the seeding box. Two rotating frames are rotatably connected to the outside of the mounting post.

[0015] 2. Through the damping shock absorbers installed at the bottom of the outer edge bracket, the present invention can buffer rough roads such as mountain roads, and can adjust the size of the damping oil outlet through screws according to the actual road conditions to ensure the stable driving of the seeder. At the same time, structures such as the connecting rod, L-shaped rod, limit frame and guide rod rotatably connected to the bottom of the central bracket can make the ditch plow always maintain an appropriate soil penetration depth when driving on different terrains, adapting to undulating terrains such as mountains and hills, and solving the problem that it is difficult to stabilize the operation posture of the seeder in complex terrains.

[0016] 3. By installing the inclined shovel outside the seeding pipe, the present invention can cut open the soil in advance to form a groove, which is convenient for seed sowing. At the same time, it can push aside the wet soil to prevent the seeding pipe from being blocked, avoiding the situation of uneven seeding density and improving the seeding quality.

[0017] 4. Through the watering mechanism, the present invention can provide water for the seeds in time after seeding. The water tank is connected to the water tank through a conduit. The piston in the water tank uses a one-way valve to extract and spray water under the action of the cam rotation. After the seeds are sown, it can quickly create a suitable humidity environment for them, meet the conditions required for seed germination, improve the seed germination rate, promote the rapid growth and development of the seeds, and solve the problem that the complex terrain in mountainous areas leads to inconvenient irrigation and affects seed germination.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings 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 shall fall within the protection scope of the present invention.

[0021] Please refer to the attached Figure 1 - attached Figure 7, an embodiment of the present invention provides a multi-scenario assisted precision seeder, which includes two outer edge brackets 1 and four groups of tires 16. The number of each group of tires 16 is two. A central bracket 2 is fixedly connected to the outside of the two outer edge brackets 1. Two seeding boxes 3 are slidably connected to the bottom of the central bracket 2. A spoon wheel structure is arranged inside the seeding box 3. During the rotation of the spoons on the spoon wheel, seeds are scooped up in sequence. When the spoon rotates to a position corresponding to the seeding tube 7, the seeds fall from the spoon into the seeding tube 7 by their own gravity, thereby realizing quantitative seeding. Two cylindrical gears 33 are rotatably connected to the bottom of the central bracket 2. A driving motor 4 is installed outside the central bracket 2. The output end of the driving motor 4 is fixedly connected to the top center of one of the cylindrical gears 33. A toothed ring 5 is arranged outside the central bracket 2. Two rack plates 6 are arranged inside the toothed ring 5. The bottom of the rack plate 6 is fixedly connected to the corresponding seeding box 3 through a long rod. When the driving motor 4 is started, its output shaft drives the connected cylindrical gear 33 to rotate. This cylindrical gear 33 meshes with the other cylindrical gear 33 to achieve synchronous rotation. The two cylindrical gears 33 also mesh with the toothed ring 5. When the cylindrical gear 33 rotates, it drives the toothed ring 5 to rotate. The rack plate 6 inside the toothed ring 5 is driven by the toothed ring 5 to move linearly along the bottom of the central bracket 2 and is connected to the seeding box 3 through a long rod, thereby realizing the sliding of the seeding box 3 at the bottom of the central bracket 2. This structure can flexibly adjust the position of the seeding box 3 according to different seeding requirements.

[0022] Two watering mechanisms are arranged outside the central bracket 2. The watering mechanism includes a water tank 23 and a water tank 25. The water tank 23 and the water tank 25 are respectively arranged at the top and bottom of the central bracket 2. A conduit 24 is fixedly connected between the water tank 23 and the water tank 25. One end of the water tank 25 is fixedly connected with a water outlet pipe 34, and a spray head is installed at one end of the water outlet pipe 34. A spring movable rod 26 is slidably connected to the internal through hole of the water tank 25. One end of the spring movable rod 26 is fixedly connected with a piston, and the other end of the spring movable rod 26 is in contact with the outside of the cam 27. The water tank 23 is used to store irrigation water and is connected to the water tank 25 through the conduit 24 to ensure the continuous supply of water. Under the action of the cam 27, the piston reciprocates in the water tank 25, realizing the extraction and spraying of water, providing moisture for the seeds in time after sowing, and improving the germination rate of the seeds.

[0023] The bottom of the seeding box 3 is fixedly connected with a seeding pipe 7. An inclined shovel 8 is arranged outside one of the seeding pipes 7. The inclined shovel 8 is installed outside one of the seeding pipes 7. During the forward movement of the seeder, the inclined shovel 8 will contact the soil prior to the seeding pipe 7, cut open the soil to form a small groove, enabling the seeding pipe 7 to smoothly spread the seeds into the groove. At the same time, the inclined shovel 8 can push the wet soil to both sides to prevent the soil from clogging the seeding pipe 7. A feeding funnel 9 is arranged at the top of the seeding box 3. First, the seeds are put into the two feeding funnels 9, and the seeds will enter the interior of the seeding box 3.

[0024] A power mechanism is arranged at the bottom of one of the outer edge brackets 1. The power mechanism includes a power box 11. A double-shaft motor is arranged inside the power box 11, and the output end of the double-shaft motor is fixedly connected with a transmission rod. One end of the transmission rod is fixedly connected with the rotating shaft of a set of tires 16. Start the double-shaft motor inside the power box 11 to drive the tires 16 to rotate. The two output ends of the double-shaft motor work synchronously, so that the transmission rod connected thereto drives the corresponding tire 16 rotating shaft to rotate, thereby providing forward power for the seeder.

[0025] A limiting ring 13 is fixedly connected to the bottom of one of the outer edge brackets 1. A hanging rod 12 is fixedly connected to the top of the power box 11. The outer side of the hanging rod 12 is slidably connected with the inner side of the limiting ring 13. A rotating rod 10 is rotatably connected inside the two seeding boxes 3. Pulley wheels 28 are sleeved on the outside of the rotating rod 10 and the outside of the transmission rod. The rotating shaft of the tire 16 is fixedly connected with the transmission rod. The transmission rod and the rotating rod 10 are connected by a belt drive system composed of pulley wheels 28 and belts. When the tire 16 rotates, the transmission rod rotates synchronously, and drives the rotating rod 10 to rotate through the friction of the belt. Both ends of the rotating rod 10 are fixedly connected with cams 27. When the rotating rod 10 rotates, the cams 27 are driven to rotate. The cams 27 are fixed at both ends of the rotating rod 10. When the rotating rod 10 rotates, the cams 27 rotate synchronously. Check valves are arranged at the joints of the conduit 24 and the water outlet pipe 34 inside the water tank 25. When the cam 27 pushes the spring movable rod 26 to move the piston away from the cam 27, a negative pressure is formed inside the water tank 25. Since the conduit 24 is connected to the water tank 23 and the check valve at the connection of the conduit 24 allows water to flow from the water tank 23 to the water tank 25, the water in the water tank 23 is sucked into the water tank 25 at this time; when the cam 27 rotates to reset the spring movable rod 26 and the piston moves towards the cam 27, the water pressure inside the water tank 25 increases, the check valve at the joint of the water outlet pipe 34 opens, and the water flows out from the water outlet pipe 34 and is then sprayed through the nozzle.

[0026] There are two damping shock absorbers 14 installed at the bottom of the outer edge bracket 1. Screws 15 are arranged on the outside of the damping shock absorbers 14. The bottom end of the damping shock absorbers 14 is rotatably connected to a set of tires 16. When the seeder moves forward, the damping shock absorbers 14 can buffer the mountain road. There is damping oil inside the damping shock absorbers 14. During the vehicle driving process, due to the bumpy road surface, the piston rod of the damping shock absorbers 14 will reciprocate relative to the cylinder barrel. The damping oil flows through the damping oil outlet under the extrusion of the piston, generating a damping force, absorbing and consuming the vibration energy, reducing the bump of the vehicle, and the size of the damping oil outlet in the damping shock absorbers 14 can be adjusted by the screws 15 according to the actual road conditions. When encountering a rough mountain road, the damping oil outlet can be appropriately adjusted to be smaller to increase the damping force and improve the driving stability of the vehicle; on a relatively flat road surface, the outlet can be appropriately adjusted to be larger to make the shock absorption softer.

[0027] There are two connecting rods 18 rotatably connected to the bottom of the central bracket 2. One end of the connecting rod 18 is rotatably connected to the outside of the L-shaped rod 17. A limiting frame 19 is fixedly connected to the outside of the central bracket 2. The outside of the L-shaped rod 17 is slidably connected to the inside of the limiting frame 19. A guide rod 20 is fixedly connected to the bottom of the central bracket 2. One end of the L-shaped rod 17 is sleeved on the outside of the guide rod 20. When the seeder travels on different terrains, the undulation of the ground will cause the height of the tires 16 to change, and then drive the outer edge bracket 1 to move up and down relative to the central bracket 2. The movement of the outer edge bracket 1 is transmitted to the L-shaped rod 17 through the connecting rod 18. The L-shaped rod 17 slides in the limiting frame 19 and moves along the guide rod 20, ensuring the stability of the movement of the L-shaped rod 17, so that the plow 21 fixed at the bottom of the L-shaped rod 17 can always maintain an appropriate soil penetration depth to meet the seeding requirements of different terrains. A plow 21 is fixedly connected to the bottom of the L-shaped rod 17. Starting the vibration cylinder 22 in cooperation with the plow 21 can reclaim the hard ground. When the vibration cylinder 22 works, it will generate high-frequency vibration. This vibration is transmitted to the plow 21, making it easier to break hard soil blocks with the help of the vibration force during the process of the plow 21 cutting into the soil downward, reducing the reclaiming resistance and improving the reclaiming efficiency. The vibration cylinder 22 is installed outside the plow 21.

[0028] The bottom of the seeding box 3 is fixedly connected with an installation column 29. Two rotating frames 30 are rotatably connected to the outside of the installation column 29. An earth covering roller frame 31 is rotatably connected to the outside of the rotating frame 30. A tension spring 32 is arranged between the earth covering roller frame 31 and the rotating frame 30. The tension spring 32 is always in a stretched state, providing a pulling force towards the ground direction for the earth covering roller frame 31. During the running of the seeder, when the earth covering roller frame 31 encounters obstacles such as large soil clods, the tension spring 32 will undergo elastic deformation, enabling the earth covering roller frame 31 to appropriately avoid the obstacles and prevent damage. After the obstacle passes, the elastic force of the tension spring 32 can make the earth covering roller frame 31 quickly return to its original working position, ensuring the continuity and stability of the earth covering work. The earth covering roller frame 31 will cover the soil ploughed by the furrow opener 21 again to bury the seeds. The earth covering roller frame 31 is rotatably connected to the installation column 29 through the rotating frame 30. When the seeder moves forward, the earth covering roller frame 31 rotates along with the rotating frame 30, pushing the soil turned up by the furrow opener 21 back to both sides and covering the sown seeds.

[0029] Specifically, first, the seeds are put into the two feeding funnels 9. The design of the feeding funnels 9 facilitates the concentrated and smooth entry of the seeds into the sowing box 3. After the seeds enter the sowing box 3, the spoon wheel structure inside the box starts to function. The spoon wheel is evenly distributed with spoon buckets. As the spoon wheel rotates, the spoon buckets scoop up the seeds in turn. When the spoon bucket rotates to a specific position corresponding to the sowing pipe 7, the seeds fall from the spoon bucket into the sowing pipe 7 by their own gravity. This design realizes precise quantitative sowing, ensures that the number of seeds at each sowing position is relatively stable, avoids waste or uneven sowing of seeds, and lays a foundation for the uniform growth of the subsequent seeds. The driving motor 4 can be started to drive the cylindrical gear 33 to rotate, so that the rack plate 6 drives the sowing box 3 to move to adjust the sowing spacing. Then, the double-shaft motor inside the power box 11 is started. The double-shaft motor in the power box 11 is the core power source, and its two output ends work synchronously. The transmission rods fixedly connected to the output ends transmit the rotational power of the motor. One end is fixedly connected to the rotating shaft of a group of tires 16, thereby driving the tires 16 to rotate. The rotation of the tires 16 provides forward power for the entire seeder, enabling it to move in farmland with different terrains and carry out sowing operations. When the seeder moves forward, the damping shock absorbers 14 installed at the bottom of the outer edge bracket 1 play an important role. The damping shock absorbers 14 are filled with damping oil. When the vehicle travels on rough roads such as mountain roads, due to the bumpy road surface, the piston rod of the damping shock absorber 14 will reciprocate relative to the cylinder barrel. During this process, the damping oil flows through the damping oil outlet under the extrusion of the piston, generating a damping force. The damping force can absorb and consume the vibration energy generated by the vehicle due to the bumpy road surface, effectively reducing the bumpiness of the vehicle and providing a relatively stable operating environment for the equipment and operators on the seeder. Moreover, the size of the damping oil outlet in the damping shock absorber 14 can be adjusted by the screw 15 according to the actual road conditions. Then, the vibration cylinder 22 is started to cooperate with the ditching plow 21 to reclaim the hard ground. When the vibration cylinder 22 works, it will generate high-frequency vibration. This high-frequency vibration is transmitted to the ditching plow 21 through the connection part with the ditching plow 21. When the ditching plow 21 cuts into the soil downward, with the help of the vibration force, it can more easily break the hard soil clods. As the tires 16 rotate, the rotating shaft of the tires 16 drives the transmission rod fixedly connected to it to rotate synchronously. The transmission rod is connected to the rotating rod 10 through a belt drive system composed of a pulley 28 and a belt. Under the action of the friction force of the belt, the rotating rod 10 is driven to rotate. The rotation of the rotating rod 10 in turn makes the spoon wheel inside the sowing box 3 rotate synchronously, so that the seeds fall from the sowing pipe 7. The inclined shovel 8 can push the wet soil to both sides, effectively preventing the soil from adhering and blocking the sowing pipe 7 due to wetness, and ensuring the continuity and stability of the sowing process.After sowing is completed, the soil covering roller frame 31 starts to work. The soil covering roller frame 31 is rotatably connected to the mounting column 29 through the rotating frame 30. When the seeder advances, the soil covering roller frame 31 rotates following the rotating frame 30. The soil covering roller frame 31 will cover the soil plowed by the furrow opener 21 again, thereby burying the seeds. When the rotating rod 10 rotates, the cams 27 fixedly connected to both ends thereof also rotate accordingly. Check valves are provided at the connections between the inside of the water tank 25, the conduit 24, and the water outlet pipe 34. When the cam 27 rotates, its eccentric contour will push the spring movable rod 26 to move reciprocally. When the cam 27 pushes the spring movable rod 26 to move the piston away from the cam 27, a negative pressure is formed inside the water tank 25. Since the conduit 24 is connected to the water tank 23 and the check valve at the connection of the conduit 24 allows water to flow from the water tank 23 to the water tank 25, the water in the water tank 23 is sucked into the water tank 25 at this time, realizing the process of water extraction, and then it is sprayed onto the sown area through the nozzle. This watering process provides water for the sown seeds in a timely manner, meets the humidity conditions required for seed germination, improves the germination rate of the seeds, and promotes the rapid growth and development of the seeds, thus realizing a complete sowing process.

[0030] Working principle: First, the seeds are put into the two feeding funnels 9. The seeds will enter the inside of the sowing box 3. A spoon wheel structure is provided inside the sowing box 3 for sowing. Then, the double-shaft motor inside the power box 11 is started to drive the tire 16 to rotate. When the seeder advances, the damping shock absorber 14 can buffer the mountain road, and the size of the damping oil outlet in the damping shock absorber 14 can be adjusted through the screw 15 according to the actual road conditions. Then, the vibration cylinder 22 is started to cooperate with the furrow opener 21 to reclaim the hard ground. When the tire 16 rotates, the belt pulley 28 will drive the rotating rod 10 to rotate. In this way, the spoon wheel inside the sowing box 3 can make the seeds fall from the sowing pipe 7. The inclined shovel 8 can prevent the wet land from affecting the sowing pipe 7. Then, the soil covering roller frame 31 will cover the soil plowed by the furrow opener 21 again and bury the seeds. When the rotating rod 10 rotates, the cam 27 will rotate accordingly. Check valves are provided at the connections between the inside of the water tank 25, the conduit 24, and the water outlet pipe 34, and the water in the water tank 23 can be pumped out when the piston moves, and then it is sprayed through the nozzle. In this way, a complete sowing process is realized.
