Description

Technical Field

[0001] This invention relates to the field of compost tea preparation technology, and in particular to a sheep manure compost tea preparation device. Background Technology

[0002] The preparation of compost tea is not simply to extract soluble nutrients from sheep manure, but to increase the reproduction of beneficial microorganisms in the nutrients through aerobic fermentation. Therefore, some molasses needs to be added during the preparation of compost tea to promote the propagation of microorganisms. Due to its characteristics of fast fertilizer effect, easy absorption and convenient application, it is widely used in integrated water and fertilizer irrigation in facility agriculture, orchards, vegetable gardens and other scenarios. The preparation process of compost tea is divided into four main stages: raw material preparation, mixing and reaction, solid-liquid separation, and storage and application. Among them, the mixing and reaction stage is particularly critical, but there are also some significant problems. Specifically, in this stage, uneven mixing of solids and liquids often occurs, directly leading to low nutrient dissolution efficiency. Currently, most traditional mixing equipment uses a unidirectional mixing method, which easily creates dead zones inside the tank during actual operation. This prevents sheep manure particles from being fully dispersed, causing them to settle at the bottom of the tank or float on the liquid surface, making it difficult for them to fully contact the water. As a result, the important nutrients in sheep manure, such as insoluble nitrogen, phosphorus, potassium, and humic acid, cannot be efficiently dissolved due to insufficient contact with the liquid. Furthermore, the current equipment has poor oxygenation, typically using a single bottom aerator, resulting in uneven oxygen distribution within the tank. The upper layer has sufficient dissolved oxygen, while the lower layer easily forms an anaerobic zone, leading to poor fermentation of compost tea. Consequently, the resulting compost tea has unstable fertilizer effects and significant quality fluctuations. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a sheep manure compost tea preparation device. Through a stirring mechanism, the device optimizes the mixing effect of sheep manure in the reaction cylinder, eliminates dead zones in the mixing, and makes the sheep manure more uniformly mixed, avoiding the stratification of oxygen content between the upper and lower layers caused by uneven mixing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a sheep manure compost tea preparation device. By setting up a stirring mechanism, the mixing effect of sheep manure inside the reaction cylinder can be greatly optimized, effectively eliminating the problem of possible stirring dead zones inside the reaction cylinder, so that the sheep manure is mixed more evenly in the reaction cylinder. In this way, it can prevent the adverse situation of excessively high or low sheep manure concentration in local areas, thereby ensuring that all areas in the reaction cylinder can maintain a consistent reaction progress, and effectively avoiding the stratification phenomenon of sufficient oxygen in the upper layer and lack of oxygen in the lower layer caused by uneven mixing.

[0016] This invention provides a sheep manure compost tea preparation device. By setting up an aeration mechanism, it can achieve the purpose of zoned aeration, thereby ensuring that the dissolved oxygen content inside the reaction cylinder is always in a uniform and stable state. This effectively solves the problem of uneven oxygen distribution in the reaction cylinder, which causes sufficient dissolved oxygen in the upper layer and easy formation of an anaerobic zone in the lower layer.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] Example 1: Please refer to Figure 1 - Figure 17 A sheep manure compost tea preparation device includes a frame 1, a reaction cylinder 2 fixed on the frame 1, and a feed inlet 3 on the reaction cylinder 2. A feed hopper 4 is fixed on the feed inlet 3 and a switch mechanism 5 is provided on the feed hopper 4 to open and close the feed position. A stirring mechanism 6 is provided on the reaction cylinder 2 for mixing and stirring the sheep manure. A lifting mechanism 7 is provided on the reaction cylinder 2 for lifting and lowering the stirring mechanism 6. A discharge pipe 8 is fixed on the reaction cylinder 2 and an electromagnetic material valve 9 is fixed on the discharge pipe 8. A pressure relief valve is provided on the reaction cylinder 2 to balance the air pressure inside the reaction cylinder 2, discharge waste gas, and ensure equipment safety. Specifically, a heat insulation shell 58 is fixed on the reaction cylinder 2, and a groove 59 is provided on the heat insulation shell 58 to allow the feed hopper 4 to pass through. A polyurethane board 60 is fixed inside the heat insulation shell 58. Among them, the opening and closing action of the electromagnetic material valve 9 is controlled by the on and off of the electromagnetic signal, which is used to quickly open or close the feeding pipe 8 to achieve the purpose of quantitative feeding of sheep manure compost tea. The electromagnetic material valve 9 is an existing product to achieve precise control of the feeding of sheep manure compost tea. This is a conventional setting in this field, so it will not be described in detail here. In addition, molasses needs to be added when preparing vegetation compost tea, and the amount of molasses added should be about 5% of the total liquid volume. It should be noted that by adding sheep manure into the feed hopper 4 in a certain proportion, the solid-liquid ratio is usually controlled in the range of 1:5-1:10, and oxygen is continuously supplied by the aeration components to maintain the dissolved oxygen content in the reaction tank 2 at 5-8 mg / L, thus maintaining the activity of aerobic microorganisms. The reaction temperature is controlled at 25-35℃, and the reaction time is 24-72 hours. When the sheep manure composting reaction is completed, stirring and aeration are stopped, and the mixture is left to stand for about 30 minutes. The mixture is then discharged from the discharge pipe 8 and subjected to solid-liquid separation treatment. This is a conventional setting in this field, so it will not be described in detail here. It should also be noted that the aerobic microbial metabolism of sheep manure compost tea is stable in an environment of 25-35℃. The heat insulation shell 58 and polyurethane board 60 can isolate external temperature changes, avoid the low temperature of reaction cylinder 2 in winter which inhibits microbial activity, or the high temperature in summer which causes microbial death, thus ensuring the nutrient conversion efficiency and the stable quality of compost tea. The heat insulation shell 58 and polyurethane board 60 can reduce heat loss and reduce the heating energy consumption required to maintain the temperature.

[0026] Furthermore, the frame 1 is equipped with an aeration mechanism 45 adapted to the reaction cylinder 2. The aeration mechanism 45 includes: an aeration ring 46 fixed inside the reaction cylinder 2; an air pump 47 fixed on the frame 1 via a base; and several circumferentially distributed support seats 48 fixed on the frame 1. A connecting pipe 49 is fixed on every two support seats 48. An aeration head 50 is fixed at one end of the connecting pipe 49 extending into the reaction cylinder 2. A connecting pipe a51 is fixed on the connecting pipe 49 via a connector a53. A pipe body a52 is fixed on the connecting pipe a51 via a connector b54. The other end of the pipe body a52 is fixed to the output end of the air pump 47. The connector b54 is fixed to the aeration ring 46 via the pipe body b. Among them, the aeration ring 46 continuously oxygenates the bottom of the reaction cylinder 2 with compressed air, increases the contact area with the liquid, and improves the oxygen dissolution efficiency. The aeration head 50 is responsible for oxygenating the liquid in the middle and upper layers of the reaction cylinder 2, so as to avoid the problem of stratification where the bottom has sufficient dissolved oxygen and the upper layer has insufficient dissolved oxygen. It should be noted that by setting up the aeration mechanism 45, the purpose of zoned aeration can be achieved, thereby ensuring that the dissolved oxygen content inside the reaction cylinder 2 is always in a uniform and stable state. This effectively solves the problem of uneven oxygen distribution in the reaction cylinder 2, which causes sufficient dissolved oxygen in the upper layer and an anaerobic zone to easily form in the lower layer. This makes the oxygen distribution in the reaction cylinder 2 more reasonable and balanced, providing a stable dissolved oxygen environment for the sheep manure composting tea reaction process. The principle of oxygenation and aeration in reaction cylinder 2 is as follows: Air is compressed by air pump 47 and the compressed air is delivered to the connecting pipe a51 through pipe a52 and connector b54. The compressed air is then delivered to the connecting pipe 49 through connector a53, so that the compressed air is distributed to the aeration ring 46 and aeration head 50. This achieves the purpose of continuous oxygenation and aeration of the bottom and upper middle layers of sheep manure compost tea in reaction cylinder 2, ensuring that the sheep manure compost tea reaction maintains a stable dissolved oxygen environment.

[0027] Furthermore, the switching mechanism 5 includes: a bracket a10 fixed on the feed hopper 4, and a cover plate 11 is provided on the feed hopper 4. A bracket b12 is fixed on the cover plate 11. A hinge seat is fixed on the bracket a10, and a rotating rod is fixed on the hinge seat. The bracket b12 is rotatably connected to the rotating rod. A rod body 13 is fixed on the bracket b12, and an electric push rod a14 is rotatably connected to the bracket a10. The output end of the electric push rod a14 is rotatably connected to the rod body 13 through a connecting ring a15. It should be noted that by setting the switch mechanism 5, the opening and closing of the cover plate 11 can be completed automatically and efficiently. After the sheep manure feeding work is completed, it can ensure that the cover plate 11 at the feed hopper 4 is closed quickly, without the need for manual operation of the cover plate 11. This greatly simplifies the operation process, reduces the number of manual intervention links, and further improves the overall efficiency of the stacked tea preparation work, making the entire preparation process smoother and more efficient. The principle of using the switching mechanism 5 to switch the cover plate 11 is as follows: Driven by the electric push rod a14, the bracket b12 and the cover plate 11 are rotated along the axis of the rotating rod until the cover plate 11 is opened to a suitable angle position, thus completing the opening action of the cover plate 11. When the cover plate 11 needs to be closed, the electric push rod a14 drives the bracket b12 and the cover plate 11 to rotate and abut against the hopper, thus completing the closing action of the cover plate 11.

[0028] Example 2: Please refer to Figure 5 - Figure 11 This embodiment further explains Example 1, the difference being that it involves a method of stirring and reacting sheep manure piled in the reaction cylinder 2.

[0029] Furthermore, the stirring mechanism 6 includes: a housing 16 disposed inside the reaction cylinder 2; a drive shaft 17 rotatably connected to the housing 16; a drive motor a18 fixed to the housing 16; the output shaft of the drive motor a18 being connected to the drive shaft 17 via a pulley 19 and a belt 20; a rotating shaft 21 rotatably connected to the housing 16; a large gear 22 fixed to the rotating shaft 21; a small gear 23 meshing with the large gear 22 fixed to the drive shaft 17; a transmission disc 24 fixed to one end of the rotating shaft 21; the transmission disc 24 being rotatably connected to the housing 16; a toothed ring 25 fixed to the housing 16; and a stirring rod 26 rotatably connected to the transmission disc 24. A spur gear 27 is fixed on the stirring rod 26 and meshes with the toothed ring 25. An installation ring 55 is fixed on the stirring rod 26, and a blade stirring head 56 is sleeved on the stirring rod 26. A nut 57 is threaded on the stirring rod 26 and contacts the blade stirring head 56. Several blades 61 are fixed on the blade stirring head 56. By setting the nut 57, stirring heads of different specifications can be replaced for operation. The central axis of the transmission disc 24 is collinear with the central axis of the reaction cylinder 2. The cross-section of the reaction cylinder 2 is convex. By adding blades 61, it is possible to crush straw and other crops that may be mixed in with sheep manure, thereby improving the preparation effect of compost tea. The transmission disc 24 is equipped with a wall scraping assembly 28, which is used to scrape the inner wall of the reaction cylinder 2. The wall scraping assembly 28 includes: a mounting base 40 fixed on the transmission disc 24, a mounting rod 41 fixed on the mounting base 40, a scraper 42 slidingly passing through the mounting rod 41 and in contact with the inner wall of the reaction cylinder 2, and an electric push rod b43 fixed on the mounting base 40. The output end of the electric push rod b43 is fixed to the scraper 42 through a connecting ring b, so as to realize the position adjustment of the scraper 42 and effectively adjust the distance between the scraper 42 and the inner wall of the reaction cylinder 2. Specifically, by setting up the blade stirring head 56, when the blade stirring head 56 rotates, it will drive the liquid in the reaction cylinder 2 to form turbulence. The shear force and thrust generated can break up the sheep manure particles deposited at the bottom of the reaction cylinder 2, making them suspended in the water, increasing the contact area between the sheep manure and the water, and accelerating the dissolution of soluble nutrients. It should be noted that by setting up the stirring mechanism 6, the mixing effect of sheep manure inside the reaction cylinder 2 can be greatly optimized, effectively eliminating the problem of possible stirring dead zones inside the reaction cylinder 2, so that the sheep manure is mixed more evenly in the reaction cylinder 2. In this way, it can prevent the adverse situation of excessively high or low concentration of sheep manure in local areas, thereby ensuring that all areas in the reaction cylinder 2 can maintain a consistent reaction progress, effectively avoiding the stratification phenomenon of sufficient oxygen in the upper layer and lack of oxygen in the lower layer due to uneven mixing; It should also be noted that by setting up the wall scraping component 28, the scraper 42 can be effectively driven to continuously scrape the inner wall of the reaction cylinder 2, which can prevent sheep manure from sticking to the inner wall of the reaction cylinder 2 during the reaction process, thereby ensuring that the sheep manure and water can be fully and evenly mixed inside the reaction cylinder 2. Ensuring that the sheep manure and water are fully mixed improves the fertilizer effect of sheep manure compost tea, thereby improving the overall quality and fertilizer effect of compost tea. The stirring mechanism 6 is used to stir sheep manure. Driven by the drive motor a18 and the transmission action of pulley 19 and belt 20, the drive shaft 17 rotates under force, causing the small gear 23 to rotate synchronously. The meshing transmission action of the small gear 23 and the large gear 22 drives the rotating shaft 21 to rotate synchronously, causing the transmission disc 24 and stirring rod 26 to rotate synchronously. The meshing transmission action of the spur gear 27 and the toothed ring 25 enables the stirring rod 26 to rotate while moving in a circular motion. The stirring rod 26 and the blade stirring head 56 thoroughly mix the sheep manure and water in the reaction cylinder 2. The scraper 42 rotates synchronously with the transmission disc 24. When the position of the scraper 42 needs to be adjusted, the electric push rod b43 drives the scraper 42 to move linearly along the mounting rod 41 until it contacts the inner wall of the reaction cylinder 2, whereby the scraper 42 scrapes the inner wall of the reaction cylinder 2.

[0030] Furthermore, the lifting mechanism 7 includes: a guide rod 29 fixed on the housing 16, which slides through the reaction cylinder 2; a support rod 30 fixed on the housing 16 and slidingly through the reaction cylinder 2; a mounting box 31 fixed on the reaction cylinder 2; a drive motor b33 fixed on the mounting box 31 via a support plate 32; a shaft a34 coaxially fixed to one end of the output shaft of the drive motor b33; the shaft a34 rotatably connected to the mounting box 31; a worm gear 35 fixed on the shaft a34; and a shaft b35 rotatably connected to the mounting box 31. 6. A worm wheel 37 that meshes with the worm 35 is fixed on the shaft b36. A toothed groove 38 is provided on the support rod 30, and a transmission gear 39 that meshes with the toothed groove 38 is fixed on the shaft b36. A limit ring 44 is fixed at the end of the guide rod 29 away from the housing 16. The diameter of the limit ring 44 is larger than the diameter of the guide rod 29. The length of the guide rod 29 is the same as the length of the support rod 30. The limit ring 44 restricts the guide rod 29 and prevents the guide rod 29 from moving too far and causing it to detach from the reaction cylinder 2. It should be noted that, by taking advantage of the unique meshing characteristics between the worm gear 37 and the worm 35, and utilizing its own self-locking function, the machine housing 16 can be automatically stopped during lifting and lowering operations. This not only effectively avoids the displacement of the machine housing 16 due to external forces or inertia, but also provides more precise control during operation. The stability of the stirring mechanism 6 during lifting and lowering is significantly improved, thereby ensuring that the equipment operates more smoothly and reliably. It should also be noted that, through the setting of the lifting mechanism 7, the height of the stirring rod 26 inside the reaction cylinder 2 can be flexibly adjusted according to actual work needs, so that the stirring rod 26 can move up and down inside the reaction cylinder 2 to reach different depth positions. When the stirring rod 26 is at different depths, it can fully stir the sheep manure compost tea at different depths in the reaction cylinder 2. Whether it is the surface layer of sheep manure compost tea near the upper part of the reaction cylinder 2 or the sheep manure compost tea located in the deep lower part of the reaction cylinder 2, effective stirring can be achieved by adjusting the height of the stirring rod 26, thereby ensuring that the entire sheep manure compost tea can be uniformly stirred at all depths in the reaction cylinder 2 to meet different work requirements and achieve ideal stirring effects. The lifting mechanism 7 is used to lift the stirring mechanism 6. The lifting mechanism 7 lifts the stirring mechanism 6. Driven by the drive motor b33, the shaft a34 rotates synchronously, which drives the worm 35 to rotate synchronously. The meshing transmission between the worm 35 and the worm wheel 37 causes the shaft b36 to rotate, which in turn drives the transmission gear 39 to rotate synchronously. The meshing transmission between the transmission gear 39 and the toothed groove 38 causes the support rod 30 to rise or fall under the force, which in turn drives the housing 16 to move synchronously.

[0031] Example 3: Sheep manure is fed into hopper 4 in a specific ratio, typically controlled between 1:5 and 1:10. Aeration is continuously provided by the aeration unit to maintain dissolved oxygen levels in reaction chamber 2 at 5-8 mg / L, thus preserving aerobic microbial activity. The reaction temperature is controlled at 25-35℃, and the reaction time is 24-72 hours. After the sheep manure composting process is complete, stirring and aeration are stopped, and the mixture is allowed to stand for approximately 30 minutes. The final product is then discharged through discharge pipe 8, thus preparing the compost tea. For the application effects of compost tea, please refer to [link to relevant documentation]. Figure 15 - Figure 17 .

[0032] The experiment included two relevant factors: the addition of sheep manure and the spraying of compost tea. Each factor had three levels: Y0: no sheep manure was applied; Y1: sheep manure was applied at a rate of 15 tons / hm². 2 Y2: The amount of sheep manure applied is 30 tons / hm². 2 T0: Do not spray compost tea; T1: Spray compost tea at 200ml / m³ 2 T2: Compost tea spraying at 400ml / m³ 2 Nine treatments were created by pairwise combinations of factor levels, with each treatment replicated six times. Each treatment was set up in a separate plot with an area of ​​2 m x 1.5 m. The artificial sheepgrass grassland was established on April 16, 2025. Compost tea was sprayed once at the beginning of each month from May to August. Samples were collected on August 15, 2025 to determine the growth indicators of sheepgrass. Two-way ANOVA showed that both sheep manure application rate and compost tea spraying rate had highly significant main effects on Leymus chinensis plant height and biomass (p<0.001), and the interaction between the two was significant. Specifically, the sheep manure effect was linearly positively correlated with the Y2 treatment (30 tons / hm²). 2 Compared to the control (Y0), it increased plant height by 24.7 cm (η). 2 =0.52, F2, 45 =28.47), contributing the most; the compost tea effect is parabolic, 200 ml / m 2 (T1) is the optimal dose, while 400 ml / m 2 (T2) showed an antagonistic effect under high sheep manure conditions, and the plant height of the Y2T2 treatment was significantly reduced by 36.5% compared with Y2T1 (p<0.001). The trend of aboveground fresh weight change was consistent with plant height. The Y2T1 combination achieved the largest biomass (260.27 g / plot), an increase of 75.5% compared with the control. The fresh weight of the underground parts is more sensitive to sheep manure. The root biomass of the Y2T1 treatment was 1.99 times that of the control, but the root-to-shoot ratio remained relatively stable. The results show that 30 tons / hm 2 Apply 200 ml / m³ of sheep manure 2 Composted tea is the optimal combination, but high doses of composted tea may produce stress effects through the accumulation of allelochemicals or competition with microorganisms.
