Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilizing devices, in particular to a biological fertilizer tillage layer soil mixing fertilizing device. Background Art

[0002] In agricultural production, fertilizer is a necessary means to improve soil, promote seed germination and seedling growth, and is widely used before and after sowing to ensure the yield and quality of crops. Therefore, how to carry out reasonable fertilization operations becomes very important.

[0003] At present, most of the fertilization before sowing is done by ground spreading. Small areas are often done manually, while large areas are done by spreaders. However, after sowing, there is a slow volatilization rate and insufficient nutrients in the root and stem areas of the seeds, which affects the later growth yield. Moreover, the single application of organic fertilizers often cannot meet the nutritional needs of organisms in the early stage of growth and improve the soil, which greatly limits the growth rate and quality of seeds.

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

[0016] 1. Through the coordination between the deep fertilization parts, the material distribution parts and the distribution plate, the biological fertilizer and organic fertilizer can be applied to the designated depth area, providing nutrients for the early growth of seeds and after the root system grows, and facilitating the biological fertilizer to exert its effect. It is not restricted by traditional planting procedures and is more flexible to use.

[0017] 2. The biological fertilizer is placed at a deeper position, while the organic fertilizer is placed in a shallower area. Together with the biological fertilizer, they form a three-point layout and are distributed around the seeds, thus avoiding the occurrence of seedling burn and ensuring the nutritional needs of the plants under different growth cycles.

[0018] 3. This device can cooperate with the sowing machinery during the fertilization process to complete the operation synchronously, reduce the occupation of agricultural machinery, improve the planting efficiency of the whole process, and simplify the production process;

[0019] 4. When applying fertilizer, 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 applied, effectively reducing the accumulation of fertilizers, making it easier to exert its own effectiveness, improve soil conditions, and better absorb nutrients from the surrounding area during root growth;

[0020] 5. The first air pipe reaches the drop port along the hollow shaft. After the fertilizer falls, it is quickly blown out by airflow, shortening the discharge time in the middle, thereby improving the continuity of fertilization and avoiding blockage. In addition, the overall spraying process forms a linear distribution, the diffusion area is wider, and accumulation is avoided;

[0021] 6. The structural design of the distribution plate and the material dividing parts can complete both quantitative intermittent fertilization and continuous fertilization according to the needs of fertilization, which has a wider range of applications. The structural design of the angled breaking plate can effectively meet the needs of two sowing methods.

[0022] 7. The structural design of the guide and hydraulic drive channel can reapply a portion of fertilizer to the surface of the soil during the fertilization process, thus forming a four-point covering fertilization. Combined with subsequent irrigation operations, it can be well dissolved in the surface area, thereby ensuring the overall fertility effect;

[0023] 8. The structural design of this device can also be used for supplementary fertilizer operation in the early growth stage of crops. By raising the overall placement height, the supplementary fertilizer can be applied between the two ridges of seedlings using the deep fertilizer application part, replacing manual operation.

[0024] 9. The cooperation between the guide and the drive assembly, through power distribution, can ensure that fertilizer is supplied to the distribution plate while intermittently performing fertilization operations from the surface outlet. The structural design is reasonable and reliable, and the design of the limit plate can solve the problem of fertilizer residue in the guide channel;

[0025] 10. The hydraulic drive channel cooperates with the drive assembly to complete the power drive or separation of the guide while maintaining the continuous rotation of the main shaft, thereby completing the two-way fertilizer supply operation. BRIEF DESCRIPTION OF THE DRAWINGS

The guide member 403 is systemized, and a guide channel 406 and a material storage trough 408 are processed along the circumferential direction of the guide member 403. If the overall arrangement is 4 or 6, a limit plate 409 is provided at both ends of the guide member 403 for limiting the two ends of the guide member 403 and utilizing the contact friction between the two to maintain the stability of the guide member 403. By driving the guide member 403 to rotate intermittently, the feeding operation of the material distribution plate 5 and the surface outlet can be realized respectively. The structure is ingenious and integrated inside the support cylinder 401 to avoid being affected by the external environment and is reliable to use.

[0053] The preferred embodiment, combined with Figure 11 and Figure 12As shown, a first friction disc 10 is provided inside the right side of the guide 403, and the first friction disc 10 has a plurality of rectangular notches. At the same time, a guide strip is provided on the guide 403 for sliding connection with the rectangular notches. At the same time, a support spring 1011 in contact with the guide 403 is installed on the left side of the first friction disc 10; the driving assembly 9 includes a second friction disc 901 and a separation spring 902; the inner circle of the second friction disc 901 is also processed with a rectangular notch, and the main shaft 402 has a guide strip connected with the rectangular notch, forming a contact with the main shaft 402. Sliding connection, the right side of the second friction disc 901 is provided with a circular ring plate 903 in contact with the hydraulic drive channel 8, and the left side is in contact with the first friction disc 10 through the separation spring 902, which is used to maintain reset contact with the toggle member 806; when in use, the second friction disc 901 is pushed toward the first friction disc 10 by the toggle member 806, overcoming the elastic force of the separation spring 902, realizing contact friction between the two, completing power transmission, and driving the guide member 403 to rotate, and the design of the support spring 1011 can reduce the requirements for docking accuracy.

[0054] The preferred embodiment, combined with Figure 8 As shown, a dividing member 11 is provided between the two guide members 403 . The dividing member 11 is fixedly mounted on the main shaft 402 . As the main shaft 402 rotates, the lever on the surface of the dividing member 11 can stir the fertilizer raw materials to avoid blockage.

[0055] The preferred embodiment, combined with Figure 10 As shown, the limiting plate 409 has an irregular residual notch, which can completely discharge the fertilizer in the guide channel 406 during the rotation of the guide channel 406, thereby preventing the residual fertilizer in the guide channel 406 from accidentally falling when rotating to the surface outlet 407, thereby ensuring the accuracy of fertilization.

[0056] The preferred embodiment, combined with 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, and a plurality of branch channels 804 are respectively provided on the first channel 801, and a positioning member 805 is provided in the branch channel 804, and a pressure spring is installed at the positioning member 805, which plays a role in stabilizing pressure as a whole; a toggle member 806 in contact with the drive component 9 is provided inside the reciprocating channel 803, and the left end of the reciprocating channel 803 is connected with the branch channel 804, and the right end is connected with the second channel 802. When in use, the first channel 801 supplies oil and the second channel 802 unloads oil, pushing the toggle member 806 to move to the left, thereby realizing the power transmission of the drive component 9 to the guide member 403. When separated, the second channel 802 can supply oil.

[0057] The preferred embodiment, combined with Figure 6 and Figure 7 As shown, a plurality of fertilizer outlets 501 are evenly arranged along the feeding disc 5, and an angular breaking plate 502 is provided at the fertilizer outlet 501. A supply channel 503 connected to the fertilizer outlet 501 is provided inside the feeding disc 5. The feeding disc 5 is connected to a driving device to provide power to the feeding disc 5. During the rotation process, when the feed port of the supply channel 503 moves to the discharge port 405 of the support cylinder 401, the fertilizer is discharged from the fertilizer outlet 501 through the supply channel 503, and the angular breaking plate 502 can draw a groove of a specified depth during the rotation process to complete the placement of the fertilizer, and by controlling the rotation speed of the feeding disc 5, the fertilization time and fertilization distance can be extended accordingly.

[0058] The preferred embodiment, combined with Figure 9 、 Figure 13 and Figure 14 As shown, the end of the main shaft 402 has liquid inlets for the first channel 801 and the second channel 802, and the liquid supply plug 14 has an annular liquid supply channel, forming a rotational connection between the two. During the rotation of the main shaft 402, the liquid supply plug 14 remains stationary, and liquid supply operations can be realized for the first channel 801 or the second channel 802.

[0059] The preferred embodiment, combined with Figure 15 As shown, the support assembly 12 includes a slide rod and a sleeve; the bottom of the slide rod is connected to a bracket, which provides installation for the support tube 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 processed with an external thread, which forms a threaded connection with the frame 1. At this time, a sliding connection is adopted between the tertiary feed pipe 404 and the discharge pipe 602. By rotating the sleeve, the height of the support tube 401 can be adjusted, thereby changing the fertilization depth of the deep fertilization component 3. The operation is more flexible and can be changed according to needs.

[0060] The preferred embodiment, combined with Figure 15 As shown, a second air pipe 13 can be added at the third-level feed pipe 404 to blow the guide channel 406 to discharge the material, thereby increasing the movement speed of the fertilizer, avoiding material breakage, and making it easier to blow the fertilizer to fill the storage tank 408, thereby improving the fertilization accuracy.

[0061] The feeding device 2 mainly delivers fertilizer to the deep fertilizing component 3 and the material dividing component 4, and can adopt an existing structure, such as the seed drill part.

[0062] Working principle: The device is installed as a whole on a traditional operating machine, such as a tractor. During operation, the two feeding devices 2 respectively transport organic fertilizer and biological fertilizer into the outer cylinder 6 and the hollow shaft 7. The biological fertilizer is directly broadcast by the soil dividing piece 702 below the hollow shaft 7. The organic fertilizer is distributed by the material dividing piece and broadcast by the cloth plate 5. The sowing machine can be integrated with this device. After fertilization, sowing operations are carried out immediately. There is no need to follow the traditional planting process of fertilizing first, then rotary tilling, and then sowing. At this time, the outer cylinder 6 has broken up the land, which is conducive to subsequent sowing operations. After sowing, the fertilizer is located in the three-point area of ​​the seed, which can provide the fertilizer needs of the seed in the early growth stage and root growth, and avoid the occurrence of seed burning. It is more stable and reliable. Moreover, by driving the guide member 403 to rotate, the surface outlet 407 can also be used to quantitatively supplement fertilizer on the soil surface to form a four-point coating (reference Figure 18 ), after irrigation, effectively ensure the normal growth of seeds;

[0063] By adjusting the support assembly 12, the height position of the support cylinder 401 can also be adjusted, thereby indirectly adjusting the fertilization depth of the biological fertilizer, which can be adjusted according to the soil conditions to expand the scope of application;

[0064] This device can also be used for supplementary fertilizer operations. By raising the overall structure, the deep fertilizer application part 3 can be used to apply fertilizer between the seedlings. It can also be used for fertilizing operations on the soil surface. By increasing the overall installation height and keeping the distribution plate 5 from rotating, fertilizing operations can be continuously performed at the distribution plate 5. At the same time, the guide part 403 can be rotated, and intermittent distribution operations can be performed by the distribution plate 5 and the surface outlet 407 respectively, diversifying the usage scenarios.

[0065] The power device and the driving device can adopt existing structures, such as an electric motor with a reducer and a chain and sprocket structure to realize the driving of the hollow shaft 7, the main shaft 402 or the distribution plate 5.

[0066] Experimental example:

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

[0068] Experimental design overview:

[0069] Treatment A (control group): conventional fertilization method, spreading organic fertilizer evenly once before sowing and mixing it into the soil using a rotary tiller;

[0070] Treatment B (experimental group): A layered fertilization strategy was adopted, which included applying biofertilizer at a depth of 15 cm in the soil, applying a layer of organic fertilizer 10 cm on each side of the seeds (about 10 cm deep), and covering the surface with a thin layer of organic fertilizer.

[0071] Data Collection and Analysis:

[0072] The relevant indicators of treatment A (conventional fertilization) and treatment B (stratified fertilization) were: 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, 1000-grain weight (g) 40 and 45, final yield (kg / ha) 5000 and 5700, soil microbial count (cfu / g soil) 1.2×10^6 and 2.0×10^6

[0073] The results were analyzed as follows: seed germination rate: stratified fertilization increased the seed germination rate because the deep biological fertilizer improved the soil structure and nutrient supply; seedling growth: seedlings under stratified fertilization performed better in terms of plant height and number of leaves, which indicated that the early nutrient supply was more sufficient; root development: a stronger root system helps absorb more water and nutrients, promoting the overall health of the plant; final yield: significantly increased the number of ears per unit area, the number of grains per ear and the thousand-grain weight, thereby greatly increasing the total yield; soil microbial activity: a higher number of microorganisms indicates that the soil ecosystem is more active, which is conducive to maintaining soil fertility in the long term.

[0074] Experiment 2: Study on the effect 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 the 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 of treatment C (conventional fertilization) and treatment D (optimized stratified fertilization) were: drought resistance score (1-5) 2 and 4, disease incidence (%) 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] Analysis of results: Stress resistance: The optimized stratified fertilization significantly enhanced the drought resistance of crops and reduced the incidence of diseases. Due to better nutrient balance and microbial activity, the plant immune system was strengthened. In terms of product quality, the protein content, vitamin and total flavonoids content of the grains were improved, indicating that the stratified fertilization method not only increased the yield, but also improved the product quality. Compared with the traditional fertilization method, the optimized stratified fertilization once again showed a higher yield potential.

[0081] Therefore, through these two experiments, it can be seen that compared with the traditional single fertilization method, layered fertilization, especially the optimized design, can significantly improve the growth performance, stress resistance and product quality of wheat, which is manifested in higher seed germination rate, faster seedling growth rate, stronger root system, more ears and grains, higher thousand-grain weight and richer nutritional value. In addition, layered fertilization can enhance soil microbial activity, which helps maintain soil health and sustainable production capacity.

[0082] The recommended depth for biofertilizers is about 15 to 20 centimeters. In this area, biofertilizers contain living microorganisms (such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, growth-promoting bacteria, etc.), with more stable temperature and humidity conditions, which are conducive to the establishment and development of microbial communities. The recommended depth for applying organic fertilizers is about 10 to 15 centimeters for base fertilizers. 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 at this depth ensures that the fertilizer is in full contact with the root system, while also helping to reduce nutrient loss.

[0083] In the case of layered fertilization, biological fertilizer: applying biological fertilizer at a depth of about 15 cm helps to create a microenvironment rich in beneficial microorganisms to support the root development of crops during the growth period. The middle layer of organic fertilizer is about 10 cm on both sides of the seeds (depth of about 10 cm), which can provide sufficient nutrients without directly contacting the seeds and causing the risk of seedling burn. As for the surface organic fertilizer, applying organic fertilizer intermittently on the surface can not only maintain soil moisture, but also gradually release nutrients for crops to absorb. In this way, it can not only meet the nutrient needs of crops at different growth stages, but also effectively improve soil structure and biological activity, and promote the healthy growth of crops. However, it should be noted that the specific fertilization depth needs to be flexibly adjusted according to local soil type, climatic conditions and the specific needs of crops.
