Description

Technical Field

[0001] This invention relates to the field of organic fertilizer technology, specifically to an intelligent variable fertilizer production and application device for aging and degraded forests that coordinates soil and water management. Background Technology

[0002] With the increasing demand for ecological restoration, the improvement of aging and degraded forests (referring to forest land where trees grow slowly and ecological functions decline due to factors such as unbalanced forest structure, decreased soil fertility, and reduced microbial activity) has become one of the core tasks of forestry ecological construction. Fertilization, as a key means to improve forest soil nutrients and promote forest restoration, directly affects the restoration effect of degraded forests due to its compatibility with forest soil and water conditions, as well as the efficiency and environmental friendliness of fertilizer production and application.

[0003] Existing liquid fertilizer application equipment mostly relies on gravity conveying or simple pump pressurization. The conveying pressure is unstable. When the pressure is too low, the fertilizer flow rate is slow and it is easy to settle and block in the pipeline. When the pressure is too high, the fertilizer spraying range is out of control, resulting in waste. To address this, we propose an intelligent variable fertilizer production and application device for aging and degraded forests with coordinated water and soil regulation. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent variable fertilizer production and application device for aging and degraded forests with coordinated water and soil regulation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent variable fertilizer production and application device for water and soil synergistic regulation of aging and degraded forests, comprising a base plate, wherein a fertilizer production component, a fertilizer application component and a transportation component are provided on the upper end of the base plate;

[0006] The fertilizer-making assembly includes a storage box, a drive shaft, a scraper, a slider, and a spring. The inner wall of the storage box is slidably connected to the surface of the drive shaft. One end of the spring is connected to the surface of the drive shaft. The inner wall of the scraper is slidably connected to the surface of the drive shaft. The other end of the spring is connected to the side of the scraper. The side of the slider is connected to the inner wall of the storage box.

[0007] The fertilizer application assembly includes an infusion pipe, a roller, a cone, an air infusion pipe, an infusion drain pipe, and an exhaust pipe. One end of the cone is connected to the side of the roller, the side of the infusion pipe is connected to the inner wall of the roller, the side of the air infusion pipe is connected to the inner wall of the infusion pipe, the interior of the infusion pipe is connected to the interior of the infusion drain pipe, and the interior of the air infusion pipe is connected to the interior of the exhaust pipe.

[0008] As a further aspect of the present invention: the transport assembly includes a methane tank, a gas storage tank, a gas separator, a main pipe, a first branch pipe, and a second branch pipe. One end of the main pipe is connected to the inlet end of the gas separator, and the outlet end of the gas separator is connected to the interior of the methane tank and the gas storage tank, respectively. One end of the first branch pipe is connected to the interior of the infusion pipe, and one end of the second branch pipe is connected to the interior of the gas delivery pipe.

[0009] As a further embodiment of the present invention: a fermentation tank is connected to the upper end face of the base plate, a cover plate is bolted to the top of the fermentation tank, a servo motor is connected to the upper end face of the cover plate, the output end of the servo motor is connected to one end of a transmission shaft, the two ends of the transmission shaft are rotatably connected to the inner wall of the fermentation tank, and a feeding cover is slidably connected to the inner wall of the cover plate.

[0010] As a further aspect of the present invention: an electric telescopic rod is connected to the inner wall of the transmission shaft, the telescopic end of the electric telescopic rod is connected to the side of the slider, and the side of the slider is slidably connected to the inner wall of the transmission shaft.

[0011] As a further aspect of the present invention: the side of the scraper is slidably connected to the inner wall of the storage box, the bottom of the storage box is configured as a filter plate, and the side of the storage box is slidably connected to the inner wall of the fermentation tank.

[0012] As a further aspect of the present invention: a drive wheel is connected to the side of the infusion tube, and the side of the roller is rotatably connected to the inner wall of the base plate.

[0013] As a further aspect of the present invention: the bottom of the methane tank is connected to the upper surface of the base plate, the bottom of the gas storage tank is connected to the upper surface of the base plate, and the side of the gas separator is connected to the upper surface of the base plate.

[0014] As a further aspect of the present invention: the other end of the first branch pipe is connected to the interior of the fermentation tank, and the other end of the second branch pipe is connected to the exhaust end of the gas storage tank.

[0015] As a further embodiment of the present invention: the interior of the drain pipe is connected to the interior of the cone, and one end of the exhaust pipe is connected to the interior of the drain pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0017] 1. This invention separates a mixed gas into methane and a usable gas (such as carbon dioxide) using a gas separator. The methane is stored in a methane tank as a backup energy source, and the usable gas is stored in a gas storage tank to provide power for subsequent fertilization. This realizes the recycling of fermentation by-products, energy and power, reduces the device's dependence on external energy, and saves operating costs.

[0018] 2. When the scraper is rotated by the drive shaft, the spring causes the scraper to elastically fit against the inner wall of the storage box, which can scrape off the residual organic raw materials (such as dead branches and fallen leaves of old forests) on the box wall in real time, prevent the raw materials from sticking and clumping, which can cause uneven fermentation, ensure that the raw materials fully participate in the fermentation reaction, and improve the fertilizer conversion rate.

[0019] Assisted stirring optimizes the fermentation environment: The electric telescopic rod adjusts the position of the slider to cause the storage box to shake slightly. Combined with the stirring action of the drive shaft, this enhances the contact between the raw materials and the air (or the gas required for fermentation), providing a more uniform growth environment for fermenting microorganisms, thereby improving fermentation efficiency, shortening the fertilizer production cycle, and ensuring the uniformity of nutrients in the produced fertilizer.

[0020] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0030] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see the appendix Figure 1 - Appendix Figure 7 The present invention provides an intelligent variable fertilizer production and application device for aging and degraded forests with coordinated water and soil regulation, comprising a base plate 1, and a fertilizer production component 2, a fertilizer application component 3 and a transportation component 4 arranged on the upper end of the base plate 1.

[0032] In embodiment 1, the fertilizer production component 2 includes a storage box 24, a drive shaft 25, a scraper 26, a slider 28, and a spring 29. The inner wall of the storage box 24 is slidably connected to the surface of the drive shaft 25. One end of the spring 29 is connected to the surface of the drive shaft 25. The inner wall of the scraper 26 is slidably connected to the surface of the drive shaft 25, and the other end of the spring 29 is connected to the side of the scraper 26. The side of the slider 28 is connected to the inner wall of the storage box 24. A fermentation tank 21 is connected to the upper surface of the base plate 1. A cover plate 22 is bolted to the top of the fermentation tank 21. The upper surface of the cover plate 22 is connected to... Servo motor 23, the output end of servo motor 23 is connected to one end of drive shaft 25, both ends of drive shaft 25 are rotatably connected to the inner wall of fermentation tank 21, the inner wall of cover plate 22 is slidably connected to feeding cover, the inner wall of drive shaft 25 is connected to electric telescopic rod 27, the telescopic end of electric telescopic rod 27 is connected to the side of slider 28, the side of slider 28 is slidably connected to the inner wall of drive shaft 25, the side of scraper 26 is slidably connected to the inner wall of storage box 24, the bottom of storage box 24 is set as filter plate, and the side of storage box 24 is slidably connected to the inner wall of fermentation tank 21;

[0033] Specifically, the inner wall of the fermentation tank 21 is slidably connected to the side of the storage box 24. This design allows the storage box 24 to move slightly vertically inside the fermentation tank 21. When the electric telescopic rod 27 extends and retracts, driving the slider 28 to slide, the slider 28, through its connection with the inner wall of the storage box 24, can pull the storage box 24 to shake slightly up and down. This action can break up the organic raw materials accumulated in the storage box 24, preventing the raw materials from forming a dense layer due to gravity compaction, ensuring uniform oxygen distribution during fermentation, and improving fermentation efficiency. At the same time, the filter plate at the bottom of the storage box 24 is made of 10-20 mesh stainless steel filter screen, which can not only allow the fermented liquid fertilizer to smoothly penetrate to the bottom of the fermentation tank 21, but also intercept large impurities that are not fully decomposed (such as unrotted tree branches), preventing impurities from entering the subsequent pipelines and causing blockages.

[0034] The inner wall of the scraper 26 is slidably connected to the surface of the drive shaft 25. The spring 29 is sleeved on the outer side of the drive shaft 25 and its two ends are respectively connected to the drive shaft 25 and the scraper 26. When the drive shaft 25 rotates clockwise under the drive of the servo motor 23, the outer side of the scraper 26 is always in close contact with the inner wall of the storage box 24 due to the elastic force of the spring 29. If there is a thick layer of raw material adhering to the inner wall of the storage box 24, the scraper 26 can be buffered by the elasticity of the spring 29 when it rotates, avoiding the wear of the parts caused by hard contact between the scraper 26 and the box wall, while ensuring that the adhering raw material is completely scraped off. In addition, the speed of the servo motor 23 is adjustable. For raw materials with different humidity (such as damp fallen leaves that are easy to stick, and dry dead branches that are easy to loosen), the scraping force of the scraper 26 can be controlled by adjusting the speed. The damp raw material corresponds to a higher speed (to enhance the scraping effect), and the dry raw material corresponds to a lower speed (to avoid the raw material being overly crushed and causing dust to fly).

[0035] In Example 2, the fertilizer application component 3 includes an infusion pipe 31, a roller 32, a cone 33, an air infusion pipe 34, an infusion pipe 35, and an exhaust pipe 36. One end of the cone 33 is connected to the side of the roller 32. The side of the infusion pipe 31 is connected to the inner wall of the roller 32. The side of the air infusion pipe 34 is connected to the inner wall of the infusion pipe 31. The interior of the infusion pipe 31 is connected to the interior of the infusion pipe 35. The interior of the air infusion pipe 34 is connected to the interior of the exhaust pipe 36. A drive wheel is connected to the side of the infusion pipe 31. The side of the roller 32 is rotatably connected to the inner wall of the base plate 1. The interior of the infusion pipe 35 is connected to the interior of the cone 33. One end of the exhaust pipe 36 is connected to the interior of the infusion pipe 35.

[0036] Specifically, the large-diameter end of the cone 33 is welded and fixed to the side of the roller 32, while the small-diameter end faces the ground (as a fertilizer outlet). The interior of the cone 33 is connected to one end of the drain pipe 35, and the other end of the drain pipe 35 is vertically connected to the interior of the delivery pipe 31. One end of the exhaust pipe 36 is connected to the interior of the gas delivery pipe 34, and the other end is obliquely inserted into the interior of the drain pipe 35 (insertion depth is 1 / 3 of the diameter of the drain pipe 35). The outlet of the exhaust pipe 36 faces the cone 33. When the gas in the gas storage tank 42 enters the gas delivery pipe 34 through the second branch pipe 46, the gas is injected into the drain pipe 35 through the exhaust pipe 36, forming a high-pressure gas flow. On the one hand, the high-pressure airflow propels the liquid fertilizer in the infusion pipe 31 to flow along the drain pipe 35 to the cone 33, realizing fertilizer delivery. On the other hand, the airflow forms a gas-liquid mixture in the drain pipe 35, which can disperse any small sediment particles (such as fine humic particles remaining from fermentation) that may exist in the fertilizer, preventing particles from accumulating and clogging at the connection between the drain pipe 35 and the cone 33, ensuring a continuous and stable fertilization process. In addition, the small-diameter end of the cone 33 can be fitted with nozzles of different specifications (such as φ5mm and φ8mm nozzles). Combined with gas pressure regulation, the amount of fertilizer can be further precisely controlled to meet the needs of aging forests with different degrees of degradation.

[0037] In embodiment 3, the transport component 4 includes a methane tank 41, a gas storage tank 42, a gas separator 43, a main pipe 44, a first branch pipe 45, and a second branch pipe 46. One end of the main pipe 44 is connected to the inlet end of the gas separator 43, and the outlet end of the gas separator 43 is connected to the interior of the methane tank 41 and the gas storage tank 42 respectively. One end of the first branch pipe 45 is connected to the interior of the liquid delivery pipe 31, and one end of the second branch pipe 46 is connected to the interior of the gas delivery pipe 34. The bottom of the methane tank 41 is connected to the upper surface of the bottom plate 1, the bottom of the gas storage tank 42 is connected to the upper surface of the bottom plate 1, the side of the gas separator 43 is connected to the upper surface of the bottom plate 1, the other end of the first branch pipe 45 is connected to the interior of the fermentation tank 21, and the other end of the second branch pipe 46 is connected to the exhaust end of the gas storage tank 42.

[0038] Specifically, the inlet of the gas separator 43 is connected to the exhaust port at the top of the fermenter 21 via the main pipe 44. The mixed gas (containing methane, carbon dioxide, and a small amount of hydrogen sulfide) generated during fermentation enters the gas separator 43 through the main pipe 44. The separator uses membrane separation technology to separate methane (with a slower permeation rate) from carbon dioxide (with a faster permeation rate) by utilizing the difference in permeation rates of different gas molecules. The methane enters the methane tank 41 for storage through the first outlet of the separator, and the carbon dioxide enters the gas storage tank 42 through the second outlet. At the same time, a drain valve is provided at the bottom of the gas separator 43 to periodically discharge the condensate (formed by water vapor in the fermentation gas when it cools) accumulated in the separator, preventing the condensate from mixing into the methane tank 41 or the gas storage tank 42 and affecting the gas purity.

[0039] Working principle:

[0040] First, open the feeding cover on the top cover plate 22 of the fermentation tank 21, and put the organic raw materials (such as dead branches, fallen leaves and other old forest waste) into the storage box 24 inside the fermentation tank 21. Close the feeding cover to ensure the airtightness of the fermentation tank 21, and provide a stable environment for subsequent anaerobic and aerobic fermentation. Start the servo motor 23 on the cover plate 22. The output end of the motor drives the drive shaft 25 that runs through the storage box 24 to rotate. When the drive shaft 25 rotates, the scraper 26 connected to its surface rotates synchronously with the shaft. The scraper 26 is elastically attached to the inner wall of the storage box 24 through the spring 29, which can scrape off the raw materials remaining on the box wall, avoid the raw materials from sticking and clumping, and ensure uniform fermentation.

[0041] The electric telescopic rod 27 on the inner wall of the drive shaft 25 can extend and retract to adjust the position of the slider 28. The slider 28 is connected to the inner wall of the storage box 24. The movement of the slider 28 can cause the storage box 24 to shake slightly, further assisting in the mixing of raw materials. The bottom of the storage box 24 is a filter plate. After fermentation, the liquid and semi-liquid fertilizers formed will permeate through the filter plate to the bottom of the fermentation tank 21, completing the conversion of raw materials into fertilizer, and waiting for subsequent transportation.

[0042] During the fermentation process, a mixed gas (containing methane, carbon dioxide, etc.) is generated. This mixed gas enters the gas separator 43 through the main pipe 44 connected to the fermentation tank 21. The gas separator 43 separates the mixed gas, transferring the methane to the methane tank 41 for storage (which can be used as a backup energy source), and transferring the remaining usable gases (such as carbon dioxide) to the gas storage tank 42 for temporary storage. This achieves the resource utilization of fermentation by-products while avoiding direct gas emissions that pollute the environment.

[0043] The fertilizer collected at the bottom of the fermentation tank 21 enters the infusion pipe 31 of the fertilizer application component 3 through the first branch pipe 45. The infusion pipe 31 is connected to the inner wall of the roller 32, forming a fertilizer delivery path from the fermentation tank 21 to the first branch pipe 45 and the infusion pipe 31.

[0044] The gas temporarily stored in the gas storage tank 42 enters the gas delivery pipe 34 of the fertilizer application component 3 through the second branch pipe 46. The gas delivery pipe 34 is nested in the inner wall of the liquid delivery pipe 31, forming a gas delivery path from the gas storage tank 42 to the second branch pipe 46 and the gas delivery pipe 34, providing power for the subsequent pressurized delivery of fertilizer.

[0045] The roller 32 on the base plate 1 can rotate around its own axis. The drive wheel connected to the side of the infusion pipe 31 provides the moving power for the roller 32. The rotation of the roller 32 drives the entire fertilization assembly 3 to move along the aging forest fertilization area to achieve large-scale fertilization coverage.

[0046] Gas in the gas supply pipe 34 is injected into the drain pipe 35 connected to the infusion pipe 31 through the exhaust pipe 36. The gas pressure forces the fertilizer in the infusion pipe 31 into the drain pipe 35. The drain pipe 35 is connected to the inside of the cone 33, which serves as the fertilizer outlet. By adjusting the gas output pressure of the gas storage tank 42 (controlling the gas flow rate of the second branch pipe 46), the pressure in the drain pipe 35 can be changed, thereby adjusting the rate and dosage of fertilizer discharged from the cone 33. This enables intelligent variable fertilization (such as adjusting the amount of fertilizer applied to a single area based on the differences in soil fertility in aging forests). At the same time, the continuous injection of gas through the exhaust pipe 36 prevents fertilizer from settling and clogging in the drain pipe 35, ensuring a smooth fertilization path. This completes the entire workflow.
