Description

Technical Field

[0001] This invention relates to the field of crop planting equipment technology, specifically to a multi-functional stratified fertilization and seeding machine for crops. Background Technology

[0002] In crop cultivation, fertilization and sowing are crucial steps affecting yield and quality. Traditional fertilizer applicators typically employ a single-layer fertilization structure, where fertilizer and seeds are applied to the soil at the same depth, leading to uneven root absorption and low fertilizer utilization efficiency. To improve crop yield and fertilizer utilization, agricultural machinery is gradually developing towards precision, layered application, and multi-functional integration.

[0003] According to the research in "Design and test of precision variable-rate fertilization and seeding control system" (Jia, H., Zhang, X., & Chen, L., 2013), "existing fertilization and seeding devices generally suffer from problems such as uniform fertilization depth and unreasonable spatial distribution of fertilizer and seeds, leading to easy fertilizer loss and low utilization rate in the early stages." The research also points out that "due to the dispersed functions and insufficient precision of the control system in traditional equipment, it is difficult to achieve synchronous and coordinated operation of fertilization and seeding, resulting in low field operation efficiency and high labor intensity."

[0004] Therefore, the fundamental flaw of existing fertilization and sowing equipment lies in its inability to achieve integrated deep and shallow stratified fertilization and sowing operations, resulting in uneven fertilizer distribution, low utilization efficiency, cumbersome operation procedures, and high manual labor intensity. This leads to the dual problems of low operational accuracy and insufficient field production efficiency. Therefore, it is necessary to propose a multi-functional stratified fertilization and sowing machine for crops. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a multi-functional stratified fertilization seeder for crops, which uses deep and shallow fertilizer pipes to achieve precise stratified fertilization at different depths along the same line, simultaneously completing sowing and ridging operations, improving fertilization accuracy and fertilizer utilization, and reducing manual labor intensity.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A multi-functional layered fertilization seeder for crops includes a controller and a support frame. A first fertilizer applicator, a second fertilizer applicator, and a seed applicator are fixedly connected to the top of the support frame. A first fertilizer applicator is fixedly connected to the bottom of the first fertilizer applicator, a second fertilizer applicator is fixedly connected to the bottom of the second fertilizer applicator, a seed applicator is fixedly connected to the bottom of the seed applicator, a deep fertilizer applicator is fixedly connected to the bottom of the first fertilizer applicator, a shallow fertilizer applicator is fixedly connected to the bottom of the second fertilizer applicator, and a plurality of seed applicator pipes are fixedly connected to the bottom of the seed applicator. The deep fertilizer applicator, the shallow fertilizer applicator, and the seed applicator pipes are arranged along the forward direction of the device on the same longitudinal working baseline, and different working depths are sequentially formed on the longitudinal working baseline. The first fertilizer applicator, the second fertilizer applicator, and the seed applicator are all electrically connected to the controller. A walking component for supporting the movement of the support device is provided at the bottom of the support frame, a rotary tillage component for loosening the soil is provided on one side wall of the support frame, and a ridging component for ridging is provided at the bottom of the support frame.

[0007] The technical principles of the above solution are as follows:

[0008] The support frame is towed by a tractor, which, together with the walking assembly, moves the device. The rotary tillage assembly loosens the soil initially, then the deep fertilizer pipe opens the soil and deep fertilizer is applied through the first fertilizer application device and the first fertilizer rate regulator. After the deep fertilizer pipe moves away, the surrounding soil slides down and covers the deep fertilizer. Then, shallow fertilizer is applied through the shallow fertilizer pipe in conjunction with the second fertilizer application device and the second fertilizer rate regulator. After that, seeds are sown on both sides of the fertilizer through the seed pipe in conjunction with the seed application device and the seed rate regulator. Finally, the ridging assembly forms a ridge.

[0009] The above approach has the following beneficial effects:

[0010] 1. This invention, by setting different depths for deep and shallow fertilizer pipes, allows for the application of deep and shallow fertilizers respectively, achieving precise stratified fertilization, meeting the nutrient absorption needs of crop roots at different depths, and effectively improving fertilizer utilization.

[0011] 2. This invention integrates rotary tillage, stratified fertilization, sowing, and ridging functions into one unit, eliminating the need for separate operations in each step, significantly shortening the operation cycle, reducing the labor intensity of operators, and meeting the high-efficiency production needs of large-scale crop planting.

[0012] 3. In this invention, the first fertilizer amount regulator and the second fertilizer amount regulator are electrically connected to the controller, which can flexibly adjust the amount of fertilizer at different depths according to crop varieties and soil conditions, improve the accuracy of fertilization, and ensure planting quality.

[0013] Furthermore, several precision powder diffusers are fixedly connected to the side wall of the seed metering device. Each precision powder diffuser has a guide pipe fixedly connected to its bottom, and each precision powder diffuser is electrically connected to the controller.

[0014] Beneficial effects: The microbial agent output of the precision powdering machine can be precisely controlled by the controller, and the microbial agent can be applied simultaneously with sowing by means of the guide pipe. This optimizes the microenvironment for seed germination, improves seed germination rate and seedling survival rate, and eliminates the need for additional manual application of microbial agents, thus simplifying the operation process.

[0015] Furthermore, the walking component includes a support plate symmetrically fixedly connected to the bottom of the support frame and a second rotating shaft that passes through the support plate and rotates with the support plate. Both ends of the second rotating shaft are coaxially fixedly connected to walking wheels.

[0016] Beneficial effects: The support plate provides stable support for the second rotating shaft, and the traveling wheels work in conjunction with the second rotating shaft to achieve smooth movement of the device, reduce operating resistance, and save energy.

[0017] Furthermore, the bottom of the deep fertilizer discharge pipe is equipped with a deep trenching component for deep fertilization trenching, including a trenching shovel and a mud guide plate. The bottom of the mud guide plate is fixedly connected to the top of the trenching shovel, and the deep fertilizer discharge pipe extends through the mud guide plate and the trenching shovel to the bottom of the trenching shovel.

[0018] Beneficial effects: The trenching shovel can efficiently dig fertilizer drainage trenches, and the mud guide plate can directionally discharge the shoveled soil, preventing soil from falling back and clogging the deep fertilizer drainage pipes, ensuring the smooth laying of deep fertilizer, and the soil can be quickly and completely covered after discharge, ensuring the effect of deep fertilization and strengthening the layer isolation.

[0019] Furthermore, a trench cover is fitted at the bottom of the shallow-discharge fertilizer pipe.

[0020] Beneficial effects: Trenching can open up shallow soil, providing space for shallow fertilizer pipes to discharge fertilizer, preventing soil from clogging the shallow fertilizer pipes, and guiding the soil to quickly fall back to cover the shallow fertilizer layer, preventing the shallow fertilizer from being exposed and affecting its fertility.

[0021] Furthermore, each seeding tube has a symmetrically rotating furrowing wheel at its bottom.

[0022] Beneficial effects: The furrowing wheel rolls and opens furrows, reducing soil resistance and preventing the seed discharge pipe from getting clogged. At the same time, it ensures that the furrow depth is uniform, allowing the seeds to fall smoothly on both sides of the fertilizer, ensuring consistent sowing depth and improving sowing quality.

[0023] Furthermore, the ridging assembly includes a baffle fixedly connected to the bottom of the support frame, a ridging component fixedly connected to one side wall of the baffle, and several grinding components coaxially fixedly connected to the second rotating shaft.

[0024] Beneficial effects: The baffle pushes the soil to be squeezed and gathered, and the ridging component shapes it into a regular ridge. The grinding component rotates synchronously with the second rotating shaft to grind the surface of the ridge flat, preventing the soil from loosening and collapsing, ensuring that fertilizer and seeds are located in the furrows, and optimizing the field structure for crop growth.

[0025] Furthermore, the rotary tillage assembly includes a bracket fixedly connected to the side wall of the support frame, a drive component fixedly connected to the inner side wall of the bracket, a first rotating shaft fixedly connected to the output end of the drive component, the other end of the first rotating shaft rotatably engaging with the inner side wall of the bracket, a plurality of rotary tillage blades fixedly connected to the first rotating shaft coaxially, and the drive component being electrically connected to the controller.

[0026] Beneficial effects: The controller can adjust the speed of the drive components, causing the rotary tiller blades to rotate evenly, achieving mechanized soil loosening, ensuring soil loosening effect, providing a good soil foundation for deep and shallow fertilization and sowing, and improving nutrient absorption efficiency and operation effect.

[0027] Furthermore, the bottom end of the guide pipe passes through the ridging component and is fixedly connected to it.

[0028] Beneficial effects: The guide pipe is positioned by the ridging device to accurately deliver the microbial agent to the area around the seeds in the furrow, preventing the agent from being lost or deviated, ensuring full contact between the agent and the seeds, and maximizing the effect of the agent in improving the soil microenvironment.

[0029] Furthermore, a fixing plate is fixedly connected to the side wall of the baffle away from the ridging component, and the deep fertilizer pipe, shallow fertilizer pipe and seeding pipe all pass through the fixing plate and are fixedly connected to the fixing plate.

[0030] Beneficial effects: The fixing plate vertically positions the deep fertilizer pipe, shallow fertilizer pipe, and seeding pipe, preventing pipe displacement due to vibration during operation, ensuring the depth accuracy of layered fertilization and the accuracy of seeding position, and guaranteeing the stability of the overall operation effect.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1:

[0041] As attached Figure 1 , Figure 2 and Figure 4As shown: A multi-functional layered fertilization seeder for crops includes a controller and a support frame 1. A first fertilizer applicator 7, a second fertilizer applicator 8, and a seed applicator 9 are bolted to the top of the support frame 1. A first fertilizer applicator 7 is fixedly connected to the bottom of a first fertilizer quantity regulator 10. A second fertilizer applicator 8 is fixedly connected to the bottom of a second fertilizer quantity regulator 11. A seed applicator 9 is fixedly connected to the bottom of a seeding quantity regulator 12. A deep fertilizer applicator pipe 13 is fixedly connected to the bottom of the first fertilizer quantity regulator 10. A shallow fertilizer applicator pipe 14 is fixedly connected to the bottom of the second fertilizer quantity regulator 11. Several seed applicator pipes 19 are fixedly connected to the bottom of the seed applicator 12. The deep fertilizer applicator pipe 13, the shallow fertilizer applicator pipe 14, and the seed applicator pipes 19 are arranged along the same longitudinal working baseline along the direction of travel of the device, and different working depths are sequentially formed along this longitudinal working baseline. The first fertilizer quantity regulator 10, the second fertilizer quantity regulator 11, and the seeding quantity regulator 12 are all electrically connected to the controller.

[0042] Several precision powder dispensers 21 are bolted to the side wall of the seed metering device 9. Each precision powder dispenser 21 has a guide pipe 22 fixedly connected to its bottom. Each precision powder dispenser 21 is electrically connected to the controller.

[0043] Specifically, the support frame 1 is pulled by a tractor, which in turn moves the first fertilizer applicator 7, the second fertilizer applicator 8, and the seed applicator 9. This, in turn, moves the first fertilizer quantity regulator 10, the second fertilizer quantity regulator 11, and the seed quantity regulator 12. This drives the deep fertilizer applicator 13, the shallow fertilizer applicator 14, and several seed applicator pipes 19 to move synchronously. The deep fertilizer applicator 13 and the shallow fertilizer applicator 14 break through the soil and then discharge deep fertilizer and shallow fertilizer respectively through the first fertilizer applicator 7 and the second fertilizer applicator 8, so that the deep fertilizer and shallow fertilizer are located at different depths on the same straight line, achieving stratified fertilizer application without interference between fertilizers. The seed applicator pipe 19 breaks through the soil during movement and discharges seeds through the seed applicator 9 and the seed quantity regulator 12 for sowing. At the same time, the precision powdering machine 21 outputs microbial agents to cover the area around the seeds, optimizing the breeding environment.

[0044] like Figure 4 As shown, the bottom of the support frame 1 is provided with a walking component for the support device to move. The walking component includes a support plate 26 symmetrically bolted to the bottom of the support frame 1 and a second rotating shaft 24 that passes through the support plate 26 and rotates with the support plate 26. Both ends of the second rotating shaft 24 are coaxially bolted with walking wheels 25.

[0045] Specifically, when the tractor pulls the support frame 1, the traveling wheel 25 provides support at the rear end of the device and rotates in conjunction with the second rotating shaft 24 to assist the device in moving.

[0046] like Figure 1 and Figure 4As shown, the bottom of the support frame 1 is provided with a ridging component for ridging. The ridging component includes a baffle 2 welded to the bottom of the support frame 1. A ridging component 3 is fixedly connected to one side wall of the baffle 2. A number of grinding components 23 are coaxially bolted to the second rotating shaft 24. The bottom end of the guide pipe 22 passes through the ridging component 3 and is bolted to the ridging component 3.

[0047] Specifically, when the tractor pulls the support frame 1 to move, the support frame 1 drives the baffle 2 to move synchronously. The baffle 2 pushes the soil and compresses it. After being discharged through the ridging component 3, it forms a ridge, so that fertilizer and seeds are located in the furrow. The microbial agent is output to the furrow through the guide pipe 22. At the same time, the traveling wheel 25 drives the second rotating shaft 24 to rotate. The second rotating shaft 24 drives the grinding component 23 to rotate synchronously, grinding the formed ridge into a regular shape.

[0048] like Figure 1 As shown, a rotary tillage assembly for loosening soil is provided on one side wall of the support frame 1. The rotary tillage assembly includes a bracket 4 welded to the side wall of the support frame 1. A drive component is bolted to the inner side wall of the bracket 4. A first rotating shaft 5 is bolted to the output end of the drive component. The other end of the first rotating shaft 5 is rotatably engaged with the inner side wall of the bracket 4. Several rotary tillage blades 6 are coaxially bolted to the first rotating shaft 5. The drive component is electrically connected to the controller.

[0049] Specifically, when the tractor pulls the support frame 1 to move, the rotary tillage component at the front end of the device initially loosens the soil; the drive component drives the first rotating shaft 5 to rotate, and the first rotating shaft 5 drives the rotary tillage blade 6 to rotate, breaking up and loosening the soil.

[0050] This invention uses a rotary tillage component to initially loosen the soil, followed by a deep fertilizer discharge pipe that opens up the soil and discharges fertilizer through a first fertilizer discharge device and a first fertilizer rate regulator. After the deep fertilizer discharge pipe is moved away, the surrounding soil slides down and covers the deep fertilizer. Then, a shallow fertilizer discharge pipe is used in conjunction with a second fertilizer discharge device and a second fertilizer rate regulator to discharge fertilizer. After that, seeds are sown on both sides of the fertilizer through a seed discharge pipe in conjunction with a seed discharge device and a seed rate regulator. Finally, a ridging component forms a ridge.

[0051] Example 2:

[0052] As attached Figure 1 and Figure 2 and Figure 3As shown, the difference from Embodiment 1 is that the deep fertilizer pipe 13 is provided with a deep ditching assembly at its bottom for deep fertilization ditching. The deep ditching assembly includes a ditching shovel 15 and a mud guide plate 16. The bottom of the mud guide plate 16 is welded to the top of the ditching shovel 15. The deep fertilizer pipe 13 extends through the mud guide plate 16 and the ditching shovel 15 to below the ditching shovel 15. The bottom of the shallow fertilizer pipe 14 is fitted with a ditching cover 17. The bottom of the seed metering pipe 19 is symmetrically fitted with ditching wheels 18. The side wall of the baffle 2 away from the ridging component 3 is bolted to a fixing plate 20. The deep fertilizer pipe 13, the shallow fertilizer pipe 14, and the seed metering pipe 19 all pass through the fixing plate 20 and are bolted to the fixing plate 20.

[0053] Specifically, when the deep fertilizer drain pipe 13 moves, it drives the trenching shovel 15 and the mud guide plate 16 to move as well. The trenching shovel 15 scoops up the soil and, through the mud guide plate 16, discharges the soil in the opposite direction of the deep fertilizer drain pipe 13's movement, allowing the deep fertilizer drain pipe 13 to discharge deep fertilizer in the fertilizer draining trench opened by the trenching shovel 15. The soil discharged backward by the trenching shovel 15 and the mud guide plate 16 then covers the deep fertilizer. Subsequently, the shallow fertilizer drain pipe 14, in the soil above the deep fertilizer, drives the trenching cover 17 to cut open the soil and guides the soil back down through its curved surface. As the trenching cover 17 cuts open the soil, the shallow fertilizer drain pipe 14 discharges the shallow fertilizer. During the movement of the deep fertilizer drain pipe 13, the shallow fertilizer drain pipe 14, and the seed metering pipe 19, they are supported and stabilized by the fixing plate 20.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
