Description

Technical Field

[0001] This invention relates to the field of agricultural fertilization equipment technology, and in particular to a biological fertilizer application device for soil mixing in the topsoil. Background Technology

[0002] In agricultural production, fertilizers are an essential means of improving soil and promoting seed germination and seedling growth. They are widely used before and after sowing to ensure the yield and quality of crops. Therefore, it is very important to carry out reasonable fertilization operations.

[0003] Currently, most fertilization before sowing is done by spreading fertilizer on the ground. In small areas, manual labor is often used, while large-scale operations are carried out by seeders. However, after sowing, there are problems such as slow volatilization and insufficient nutrients in the root and stem areas of the seeds, which affects the later growth and yield. Moreover, applying organic fertilizer alone often cannot meet the nutritional needs of organisms in the early stages of growth or improve the soil condition, which greatly limits the growth rate and quality of seeds. Therefore, there is an urgent need for an agricultural device that can achieve multi-fertilizer and deep fertilization. Summary of the Invention

[0014] Preferably, multiple fertilizer outlets are evenly arranged along the fabric tray, and an angular soil-breaking plate is provided at each fertilizer outlet. The interior of the fabric tray is provided with a supply channel communicating with the fertilizer outlet.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Through the cooperation between the deep fertilization unit, the material distribution unit and the material distribution tray, bio-fertilizer and organic fertilizer can be applied to the designated depth area to provide nutrients for the early stage of seed growth and after the root system has grown. It also facilitates the effect of bio-fertilizer and is not restricted by traditional planting procedures, making it more flexible to use.

[0017] 2. The bio-fertilizer is placed in a deeper position, while the organic fertilizer is placed in a shallower area, forming a three-point layout with the bio-fertilizer, distributed around the seed area, which avoids the occurrence of seedling burn, while ensuring the nutritional needs at different growth stages.

[0018] 3. This device can work in conjunction with the sowing machinery during the fertilization process to complete the operation simultaneously, reducing the occupation of agricultural machinery, improving the planting efficiency of the entire process, and simplifying the production process;

[0019] 4. When fertilizing, the hollow shaft can swing left and right to form an S-shaped fertilization route, which increases the contact area with the soil and the amount of fertilizer, effectively reducing the accumulation of chemical fertilizer, making it easier to exert its own effectiveness, improving soil conditions, and allowing the roots to better absorb nutrients from the surrounding area during the root growth process.

[0020] 5. The first air pipe reaches the material inlet along the hollow shaft. After the fertilizer falls, the airflow is used to blow it out quickly, shortening the intermediate discharge time, thereby improving the continuity of fertilization and avoiding blockage. Moreover, the overall spraying process forms a linear distribution with a wider diffusion area, avoiding accumulation.

[0021] 6. The structural design of the feeding tray and distributing components can accommodate both quantitative intermittent fertilization and continuous fertilization according to fertilization needs, making it more versatile. Furthermore, the structural design of the angled soil-breaking plate can effectively meet the needs of both sowing methods.

[0022] 7. The structural design of the guide components and hydraulic drive channels allows for the application of additional fertilizer to the soil surface during the fertilization process, thus forming a four-point covering fertilization. Combined with subsequent irrigation operations, it can dissolve well in the surface area, thereby ensuring the overall fertility effect.

[0023] 8. The structural design of this device can also be applied to fertilization operations in the early stages of crop growth. By raising the overall placement height, the deep fertilization unit can be used to apply fertilization between two rows of seedlings, replacing manual labor.

[0024] 9. The cooperation between the guide and drive components, through power distribution, enables intermittent fertilization operations from the surface outlet while ensuring fertilizer supply to the feed tray. The structural design is reasonable and reliable, and the design of the limiting plate can solve the problem of fertilizer residue in the guide channel.

[0025] 10. The hydraulic drive channel, in conjunction with the drive assembly, can power drive or separate the guide components while maintaining the continuous rotation of the main shaft, thereby completing the bidirectional fertilizer supply operation. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0047] Specific implementation method one: Combining Figure 1-19 As shown, a bio-fertilizer topsoil mixing and fertilization device includes: a frame 1 and a material distribution plate 5. A feeding device 2 is provided above the frame 1. Multiple deep fertilization components 3 and material distribution components 4 are respectively provided in front of the frame 1. The multiple deep fertilization components 3 are arranged at intervals and are connected to the feeding device 2 through pipelines. The material distribution components 4 are located in front of the deep fertilization components 3 and are connected to the deep fertilization components 3 above through pipelines. Multiple material distribution plates 5 are arranged along the axial direction of the material distribution components 4, and two adjacent material distribution plates 5 are located on both sides of the deep fertilization components 3.

[0048] Preferred embodiments, in combination Figure 1-5As shown, the deep fertilization unit 3 includes an outer cylinder 6 and a hollow shaft 7. The top of the outer cylinder 6 is welded to the frame 1. There is a primary feed pipe 601 communicating with the internal space at the rear of the top of the outer cylinder 6, and a discharge pipe 602 is provided at the front. At the same time, the upper and lower parts of the hollow shaft 7 are connected to the outer cylinder 6 by rotating shafts. An interlayer is formed between the inner wall of the outer cylinder 6 and the inner wall of the hollow shaft 7 for organic fertilizer to fall. A secondary feed pipe 701 is provided above the hollow shaft 7, and a soil separating component 702 is provided at the bottom. During operation, the soil separating component 702 is located in the designated soil depth area. During the movement, it breaks up the soil to complete the fertilization operation. It can also drive the hollow shaft 7 to reciprocate to form an S-shaped fertilization route as needed through a power device, so as to avoid fertilizer accumulation, increase the fertilization area, and improve the fertilizer fertility effect.

[0049] Preferred embodiments, in combination Figure 4 and Figure 5 As shown, the soil separator 702 has a triangular structure with a top blade 703 at the front end for breaking up soil and small stones during the movement, and secondary blades 704 arranged on both sides. The overall flat structure can reduce resistance and facilitate the discharge of fertilizer. During the swinging process, it achieves the effect of lateral cutting. The discharge port 705, which is connected to the hollow shaft 7 at the rear, completes the fertilization operation during the movement, which is stable and reliable.

[0050] Preferred embodiments, in combination Figure 3 and Figure 5 As shown, the top of the hollow shaft 7 is provided with a first air pipe 706, which is connected to the air supply device. At the same time, the first air pipe 706 extends downward along the inner rear wall of the hollow shaft 7 to the discharge port 705, and a rectangular air outlet 707 is opened in the discharge port 705. During the fertilization process, the fertilizer that falls into the discharge port 705 can be blown out by the wind, shortening the intermediate time. In addition, the design of the discharge port 705 outlet avoids the accumulation of fertilizer and can form a near-straight arrangement of fertilizer. From the top view, it looks like a rectangular fertilizer laying surface. Moreover, the design of the first air pipe 706 can also meet the application of liquid microbial fertilizer. Specifically, the liquid microbial fertilizer flows into the discharge port 705 from the hollow shaft 7. Under the action of the wind, the liquid will be blown into a granular form to contact the soil behind, which can ensure the uniformity of diffusion and better control the amount of microbial fertilizer used.

[0051] Preferred embodiments, in combination Figure 2 and Figure 8As shown, the material distribution component 4 includes a support cylinder 401, a main shaft 402, and guide components 403. The support cylinder 401 has support assemblies 12 at both ends connected to the frame 1 to fix its position. Simultaneously, multiple three-stage feed pipes 404 connected to the deep fertilization component 3 are located above the support cylinder 401. These three-stage feed pipes 404 are connected to the discharge pipe 602, and multiple discharge ports 405 are located below, which are the installation areas for the material distribution plate 5. The main shaft 402 can be fixedly connected to the support cylinder 401 at both ends. Multiple guide components 403 are fixedly installed on the main shaft 402 and located at the three-stage feed pipes 404. Each guide component 403 has a guide channel 406. Organic fertilizer entering through the three-stage feed pipes 404 can be diverted by the guide channel 406 and enter the space areas on both sides of the guide component 403, thus achieving stable and reliable feeding of the material distribution plate 5.

[0052] Preferred embodiments, in combination Figure 8-12 As shown, in order to simultaneously meet the needs of surface fertilization, the connection between the main shaft 402 and the support cylinder 401 is changed to a rotating shaft connection, and one end of the main shaft 402 is connected to the power unit. Simultaneously, the guide 403 is sleeved with the inner wall of the support cylinder 401, and a rectangular surface outlet 407 is machined on the support cylinder 401 located below the three-stage feed pipe 404. The main shaft 402 is equipped with a hydraulic drive channel 8, and a drive assembly 9 that docks with the guide 403 is provided on the main shaft 402. By driving the drive assembly 9 through the hydraulic drive channel 8, the rotation of the guide 403 can be controlled. The guide 403 is manufactured with guide channels 406 and storage troughs 408 machined along its circumference, such as in an arrangement of 4 or 6. Each end of the guide 403 is provided with a limiting plate 409 to limit the ends of the guide 403 and to maintain the stability of the guide 403 by utilizing the contact friction between the two. By driving the guide 403 to rotate intermittently, material feeding operations can be realized for the material feeding disc 5 and the surface outlet. The structure is ingenious and integrated inside the support cylinder 401, avoiding the influence of the external environment and ensuring reliable use.

[0053] Preferred embodiments, in combination Figure 11 and Figure 12As shown, a first friction disk 10 is provided inside the right side of the guide 403. The first friction disk 10 has multiple rectangular notches, and the guide 403 has a guide strip that slides through the rectangular notches. A support spring 1011, in contact with the guide 403, is installed on the left side of the first friction disk 10. The drive assembly 9 includes a second friction disk 901 and a separation spring 902. The inner circle of the second friction disk 901 also has rectangular notches, and the main shaft 402 has a guide strip that connects to the rectangular notches, forming a connection with the main shaft 402. The sliding connection is provided. The right side of the second friction disk 901 is provided with an annular plate 903 that contacts the hydraulic drive channel 8, and the left side contacts the first friction disk 10 through a separation spring 902 to maintain the reset contact with the actuating member 806. In use, the actuating member 806 pushes the second friction disk 901 to move towards the first friction disk 10, overcoming the elastic force of the separation spring 902, realizing the contact friction between the two, completing the power transmission, and driving the guide member 403 to rotate. The design of the support spring 1011 can reduce the requirements for docking accuracy.

[0054] Preferred embodiments, in combination Figure 8 As shown, a distributor 11 is provided between the two guides 403. The distributor 11 is fixedly installed on the main shaft 402. As the main shaft 402 rotates, the lever on the surface of the distributor 11 can stir the fertilizer raw materials to avoid blockage.

[0055] Preferred embodiments, in combination Figure 10 As shown, the limiting plate 409 has an irregular notch, which can completely discharge the fertilizer in the guide channel 406 during the rotation of the guide channel 406, thereby avoiding the accidental falling of residual fertilizer in the guide channel 406 when it rotates to the surface outlet 407, and ensuring the accuracy of fertilization.

[0056] Preferred embodiments, in combination Figure 14 , Figure 16 and Figure 17 As shown, the hydraulic drive channel 8 includes a first channel 801, a second channel 802, and a reciprocating channel 803. The first channel 801, the second channel 802, and the reciprocating channel 803 are respectively arranged inside the main shaft 402. The first channel 801 is provided with multiple branch channels 804. The branch channels 804 are provided with positioning elements 805, and pressure springs are installed at the positioning elements 805, which play a role in stabilizing pressure. The reciprocating channel 803 is provided with a toggle element 806 that contacts the drive assembly 9. The left end of the reciprocating channel 803 is connected to the branch channel 804, and the right end is connected to the second channel 802. When in use, the first channel 801 supplies oil, and the second channel 802 discharges oil, pushing the toggle element 806 to the left to realize the power transmission of the drive assembly 9 to the guide 403. When separated, the second channel 802 can supply oil.

[0057] Preferred embodiments, in combination Figure 6 and Figure 7 As shown, multiple fertilizer outlets 501 are evenly arranged along the feed plate 5. An angled soil-breaking plate 502 is provided at the fertilizer outlet 501. The feed plate 5 has a supply channel 503 that communicates with the fertilizer outlet 501 inside. The feed plate 5 is connected to the drive device to provide power to the feed plate 5. During rotation, when the feed inlet of the supply channel 503 moves to the discharge outlet 405 of the support cylinder 401, fertilizer is discharged from the fertilizer outlet 501 through the supply channel 503. During rotation, the angled soil-breaking plate 502 can draw a groove of a specified depth to complete the placement of fertilizer. By controlling the rotation speed of the feed plate 5, the fertilization time and fertilization distance can be extended accordingly.

[0058] Preferred embodiments, in combination Figure 9 , Figure 13 and Figure 14 As shown, the end of the main shaft 402 has a liquid inlet of the first channel 801 and the second channel 802, and the liquid supply plug 14 has an annular liquid supply channel. The two are rotatably connected. During the rotation of the main shaft 402, the liquid supply plug 14 remains stationary, which can realize the liquid supply operation to the first channel 801 or the second channel 802.

[0059] Preferred embodiments, in combination Figure 15 As shown, the support assembly 12 includes a slide rod and a sleeve; a bracket is connected to the bottom of the slide rod, which provides for the installation of the support cylinder 401 and the drive device; the top of the slide rod is slidably connected to the sleeve, and there is an adaptive spring between the two; the outer wall of the sleeve is machined with external threads, forming a threaded connection with the frame 1; and at this time, the three-stage feed pipe 404 and the discharge pipe 602 are slidably connected. By rotating the sleeve, the height of the support cylinder 401 can be adjusted, thereby changing the fertilization depth of the deep fertilizer 3, making the operation more flexible and able to be changed according to needs.

[0060] Preferred embodiments, in combination Figure 15 As shown, a second air pipe 13 can be added at the third-stage feed pipe 404 to blow the guide channel 406 to discharge the fertilizer, improve the movement speed of the fertilizer, avoid material interruption, and facilitate the filling of the storage tank 408 with the fertilizer, thereby improving the fertilization accuracy.

[0061] The feeding device 2 mainly conveys fertilizer to the deep fertilization unit 3 and the distributing unit 4. It can adopt existing structures, such as the seeder section.

[0062] Working Principle: The device is installed on traditional machinery, such as a tractor. During operation, two feeding devices 2 respectively deliver organic fertilizer and bio-fertilizer into the outer cylinder 6 and hollow shaft 7. The bio-fertilizer is directly distributed by the soil distribution component 702 below the hollow shaft 7, while the organic fertilizer is distributed by the material distribution component and distributed by the spreading disc 5. The seeding machinery can be integrated with this device. After fertilization, sowing can be carried out immediately, eliminating the need for the traditional planting process of fertilizing first, then tilling, and then sowing. At this time, the outer cylinder 6 has already broken up the soil, which is beneficial for subsequent sowing operations. After sowing, the fertilizer is located in three points on the seed, providing the fertilizer needs for the early stage of seed growth and root development, and avoiding seed burning. This makes the process more stable and reliable. Furthermore, by driving the guide component 403 to rotate, the surface outlet 407 can also quantitatively replenish fertilizer to the soil surface, forming a four-point coverage (see reference). Figure 18 After irrigation, the normal growth of the seeds is effectively guaranteed;

[0063] The height of the support cylinder 401 can also be adjusted by adjusting the support component 12, thereby indirectly adjusting the fertilization depth of the bio-fertilizer. This can be adjusted according to soil conditions, increasing the applicability range.

[0064] This device can also be used for supplementary fertilization. By raising the overall height, fertilizer can be applied between seedlings using the deep fertilization component 3. It can also be used for surface fertilization. By increasing the overall installation height and keeping the distribution plate 5 stationary, fertilization can be continuously performed from the distribution plate 5. At the same time, the guide component 403 can be rotated to allow intermittent fertilization from the distribution plate 5 and the surface outlet 407, making it versatile for various applications.

[0065] The power unit and drive unit can use existing structures, such as an electric motor with a reducer, chain and sprocket, to drive the hollow shaft 7, main shaft 402 or cloth disc 5.

[0066] Experimental example:

[0067] Experiment 1: Comparison of stratified fertilization and traditional fertilization in wheat cultivation;

[0068] Experimental Design Overview:

[0069] Treatment A (control group): Traditional fertilization method, organic fertilizer is evenly spread once before sowing and mixed into the soil by rotary tiller;

[0070] Treatment B (experimental group): A layered fertilization strategy was adopted, including applying bio-fertilizer at a depth of 15 cm in the soil, applying a layer of organic fertilizer 10 cm away from each side of the seed (at a depth of about 10 cm), and then covering the soil surface with a thin layer of organic fertilizer.

[0071] Data collection and analysis:

[0072] The relevant indicators for treatment A (conventional fertilization) and treatment B (stratified fertilization) were as follows: seed germination rate (%) 85 and 92%, seedling height (cm) 15 and 18, number of leaves 4 and 5, root length (cm) 12 and 16, number of ears per unit area 300 and 350, number of grains per ear 35 and 40, thousand-grain weight (g) 40 and 45, final yield (kg / ha) 5000 and 5700, and soil microbial count (cfu / gsoil) 1.2×10^6 and 2.0×10^6, respectively.

[0073] The results showed that: Seed germination rate: stratified fertilization improved seed germination rate because the deep-layer bio-fertilizer improved soil structure and nutrient supply; Seedling growth: seedlings under stratified fertilization performed better in terms of both plant height and leaf number, indicating a more sufficient early nutrient supply; Root development: stronger root systems helped absorb more water and nutrients, promoting overall plant health; Final yield: significantly increased the number of spikes per unit area, the number of grains per spike, and the thousand-grain weight, thereby greatly increasing the total yield; Soil microbial activity: higher microbial counts indicated a more active soil ecosystem, which is conducive to maintaining soil fertility in the long term.

[0074] Experiment 2: Study on the effects of optimized stratified fertilization on wheat stress resistance and quality;

[0075] Experimental Design Overview:

[0076] Treatment C (control group): land preparation and fertilization were carried out in a conventional manner.

[0077] Treatment D (Improved Experimental Group): Further optimize the stratified fertilization strategy, such as increasing the amount of bio-fertilizer or changing the fertilization location.

[0078] Data collection and analysis:

[0079] The indicators for treatment C (conventional fertilization) and treatment D (optimized stratified fertilization) are: drought resistance score (1-5) 2 and 4, disease incidence rate (%) 15 and 5, grain protein content (%) 12 and 14, vitamin content (mg / kg) 20 and 25, total flavonoid content (mg / kg) 10 and 15, and final yield (kg / ha) 5000 and 6000.

[0080] Results Analysis: Stress Resistance: The optimized stratified fertilization significantly enhanced the crop's drought resistance and reduced the incidence of diseases. Due to better nutrient balance and microbial activity, the plant's immune system was strengthened. In terms of product quality, the protein content, vitamin content, and total flavonoid content of the grains were all increased. This indicates that the stratified fertilization method not only increased yield but also improved product quality. Compared with traditional fertilization methods, the optimized stratified fertilization method once again showed higher yield potential.

[0081] Therefore, these two experiments show that, compared with traditional single fertilization, stratified fertilization, especially with optimized design, can significantly improve the growth performance, stress resistance and product quality of wheat. Specifically, it manifests as higher seed germination rate, faster seedling growth rate, stronger root system, more spikes and grains, higher thousand-grain weight and richer nutritional value. In addition, stratified fertilization can also enhance soil microbial activity, which helps maintain soil health and sustainable productivity.

[0082] The recommended application depth for bio-fertilizers is generally between 15 and 20 centimeters. Within this depth, the bio-fertilizer contains live microorganisms (such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, and growth-promoting bacteria), and the temperature and humidity conditions are more stable, which is conducive to the establishment and development of the microbial community. For organic fertilizers, the recommended application depth for base fertilizers is generally between 10 and 15 centimeters. The main purpose of organic fertilizers is to improve soil structure, increase soil organic matter content, and provide a continuous supply of nutrients for crops. Applying them at this depth ensures sufficient contact between the fertilizer and the roots, while also helping to reduce nutrient loss.

[0083] When using layered fertilization, bio-fertilizer is applied at a depth of about 15 cm to create a microenvironment rich in beneficial microorganisms, supporting root development during the crop's growth period. The middle layer of organic fertilizer is applied about 10 cm away from each side of the seed (at a depth of about 10 cm). This provides sufficient nutrients without directly contacting the seed and causing the risk of burning the seedlings. The surface layer of organic fertilizer is applied intermittently on the soil surface, which not only maintains soil moisture but also gradually releases nutrients for crop absorption. In this way, the nutrient needs of crops at different growth stages can be met, and soil structure and biological activity can be effectively improved, promoting healthy crop growth. However, it should be noted that the specific fertilization depth needs to be flexibly adjusted according to local soil type, climate conditions, and the specific needs of the crop.

[0084] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
