Description

Technical Field

[0001] The present invention relates to the technical field of fertilizing devices, and in particular to a convenient low-emission manure and sewage deep-field returning device. Background Art

[0002] With the continuous development of agricultural production, the amount of manure generated by the livestock industry has increased year by year. If this manure is not handled properly, it will not only occupy a large amount of land resources, but may also cause serious pollution to the soil, water sources, and air. Therefore, how to effectively treat agricultural waste and realize its resource utilization has become a major issue facing the sustainable development of agriculture. In recent years, with the continuous advancement and innovation of microbial fermentation technology, the technology of converting manure into liquid organic fertilizer has become increasingly mature. Through the decomposition and fermentation of microorganisms, the organic matter in manure can be converted into nutrients that can be absorbed by plants, while eliminating odors and harmful substances. This technology not only improves the utilization rate of manure, but also reduces treatment costs and environmental pollution.

[0003] In the process of returning manure and organic fertilizer to the fields, the depth, amount, and time of fertilization will affect greenhouse gas emissions. The nitrogen element in liquid organic fertilizer mainly exists in the form of ammonium nitrogen and nitrate nitrogen. If the fertilization depth is too shallow, these nitrogen elements will easily be converted into ammonia and volatilized into the air after returning to the fields, especially under high temperature, high humidity or high soil pH conditions. The volatilization of ammonia not only reduces the utilization rate of fertilizers, but may also cause air pollution. In addition, the organic matter in manure will decompose and produce methane under the action of anaerobic microorganisms. When the nitrogen in manure undergoes nitrification and denitrification in the soil, it will generate nitrous oxide, which will increase the emission of greenhouse gases (methane, nitrous oxide, etc.), thereby exacerbating the global greenhouse effect and leading to environmental problems such as climate warming and an increase in extreme weather events.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] Example 1, refer to Figure 1-Figure 5 The convenient low-emission manure deep returning device includes a mounting frame 1, a traction frame 101 and a buffer connecting frame 2 are installed on the mounting frame 1, and the mounting frame 1 is connected to the traction mechanism through the traction frame 101 to ensure that the device can be stably towed. The front ditching knife group 201 is installed on the buffer connecting frame 2 on the front side, and the rear ditching knife group 202 is installed on the buffer connecting frame 2 on the rear side. The buffer connecting frame 2 can reduce vibration and impact during operation while ensuring the stability and flexibility of the ditching knife group. The buffer connecting frames 2 on the front and rear sides are staggered to ensure that the soil is effectively cut and a good groove is formed during ditching to prepare for subsequent fertilization operations. It also includes:

[0040] Deep fertilization assembly: The deep fertilization assembly is arranged on the mounting frame 1, the front trenching blade assembly 201 and the rear trenching blade assembly 202. The deep fertilization assembly can directly apply filtered fertilizer into the trench while trenching;

[0041] Vibration cleaning component: The vibration cleaning component is set in the deep fertilization component. The vibration cleaning component is used to mix fertilizers and clean clogged filter holes;

[0042] Auxiliary feeding component: The auxiliary feeding component is arranged inside the deep fertilization component. The auxiliary feeding component can automatically add material when the vibration cleaning component is working.

[0043] Furthermore, the deep fertilization component includes a fertilizer box 3 and a carrying box 5, which constitute the main body of the deep fertilization component. There are two fertilizer boxes 3, which increases the fertilizer capacity and reduces the frequency of adding fertilizer. The carrying box 5 is fixedly connected to the mounting frame 1. The fertilizer box 3 is fixedly arranged above the carrying box 5 and is connected to the carrying box 5, so that the fertilizer can flow smoothly into the carrying box 5. A filter plate 301 is provided at the connection between the fertilizer box 3 and the carrying box 5, which can filter the fertilizer to ensure that the fertilizer applied to the soil is pure and free of impurities. The bottom of the carrying box 5 is respectively connected with multiple first connecting pipes 501 and second connecting pipes 502, which transport the fertilizer to the trenching knife group to realize integrated trenching and fertilization.

[0044] It should be noted that the front trenching knife group 201 and the rear trenching knife group 202 are both provided with a liquid storage chamber 203 for temporarily storing liquid fertilizer. The bottom end of the liquid storage chamber 203 is provided with a liquid outlet 204. The end of the liquid outlet 204 passes through the bottom side wall of the front trenching knife group 201 or the rear trenching knife group 202 to ensure that the fertilizer can be accurately applied to the opened groove. The first connecting pipe 501 is fixedly connected to the corresponding front trenching knife group 201 and communicates with the liquid storage chamber 203 inside it. The second connecting pipe 502 is connected to the corresponding front trenching knife group 201. The corresponding rear trenching knife group 202 is fixedly connected and communicated with the second connecting pipe 502 inside it. The first connecting pipe 501 and the second connecting pipe 502 are respectively connected to the front trenching knife group 201 and the rear trenching knife group 202 to realize the transportation of fertilizer. The fertilizer is liquid fertilizer. The first connecting pipe 501 and the second connecting pipe 502 are both made of elastic materials that can be stretched and retracted within a certain range. They can be stretched and retracted within a certain range to adapt to the needs of different working conditions. The liquid outlet 204 is a single-pass setting to avoid the backflow of liquid fertilizer.

[0045] In this embodiment, the device is connected to a traction mechanism (such as a tractor) through a traction frame 101 on the mounting frame 1 to achieve stable traction. During operation, the front trenching knife group 201 and the rear trenching knife group 202 on the buffer connecting frames 2 on the front and rear sides are staggered to effectively cut the soil and form grooves to prepare for fertilization operations. These buffer connecting frames 2 not only reduce vibration and impact during operation, but also ensure the stability and flexibility of the trenching knife group.

[0046] The deep fertilization component is the core part of the device, which consists of a fertilizer box 3 and a carrying box 5. The fertilizer box 3 is located above the carrying box 5 and is connected to it. The fertilizer is filtered through the filter plate 301 to ensure that the fertilizer applied to the soil is pure and free of impurities. A plurality of first connecting pipes 501 and second connecting pipes 502 are provided at the bottom of the carrying box 5. These connecting pipes are made of elastic material and can be expanded and contracted within a certain range to adapt to different working conditions. They are connected to the liquid storage chamber 203 inside the trenching knife group to transport the filtered liquid fertilizer into the liquid storage chamber 203.

[0047] When the trenching knife group cuts into the soil, the liquid outlet 204 at the bottom of the liquid storage chamber 203 accurately applies the fertilizer into the trench, realizing the integrated operation of trenching and fertilizing. This design not only improves the fertilization efficiency, but also ensures the accurate application of fertilizer, reducing waste and environmental pollution.

[0048] During the entire fertilization process, since the fertilizer is filtered and directly applied into the soil grooves, the volatilization and loss of fertilizer in the air are reduced, and the pollution to the environment is reduced. At the same time, precise fertilization also helps to improve the yield and quality of crops and promote the sustainable development of agricultural production.

[0049] Example 2, refer to Figure 5-Figure 9 The vibration cleaning component includes a dual-axis motor 6 fixedly installed in the middle of the carrying box 5. The two fertilizer boxes 3 are symmetrically distributed along the dual-axis motor 6. Such a layout is not only conducive to the balance of power transmission, but also convenient for subsequent maintenance and operation. The output end of the dual-axis motor 6 is connected to the transmission shaft 601. The end of the transmission shaft 601 passes through the side wall of the fertilizer box 3 and is rotatably connected to the fertilizer box 3. A stirring paddle 602 and a plurality of mounting sleeves 7 are fixedly connected to the transmission shaft 601 located inside the fertilizer box 3. When the dual-axis motor 6 is started, the stirring paddle 602 and the mounting sleeve 7 will rotate synchronously under the drive of the transmission shaft 601, thereby fully mixing the fertilizer in the fertilizer box 3, which helps to prevent fertilizer agglomeration and ensure uniformity of fertilization.

[0050] Furthermore, the mounting sleeve 7 is hollow, and the bottom wall of the inner cavity of the mounting sleeve 7 is fixedly connected to a connecting spring 701, and the end of the connecting spring 701 is fixedly connected to a connecting rod 702, which extends to the outside of the mounting sleeve 7 and has a strong magnetic block 703 fixedly connected to its end. When the transmission shaft 601 rotates, under the action of centrifugal force, the connecting rod 702 and the strong magnetic block 703 will gradually stretch the connecting spring 701, and as the transmission shaft 601 rotates, the strong magnetic block 703 will also hit the filter plate 301.

[0051] It should be noted that the end face of the strong magnetic block 703 is set to be arc-shaped, which avoids hard collision with the filter plate 301, and also increases its contact area with the filter plate 301, thereby improving the cleaning effect. There is a gap between the end of the stirring paddle 602 and the filter plate 301, which not only ensures the normal rotation of the stirring paddle 602, but also provides space for the vibration cleaning of the strong magnetic block 703. The distance between the transmission shaft 601 and the filter plate 301 is less than the sum of the lengths of the mounting sleeve 7, the connecting rod 702 and the strong magnetic block 703, thereby ensuring that the strong magnetic block 703 can contact the filter plate 301 during the rotation of the transmission shaft 601, thereby achieving an effective vibration cleaning effect.

[0052] In this embodiment, when the dual-axis motor 6 is started, the transmission shaft 601 drives the stirring paddle 602 and the mounting sleeve 7 to rotate synchronously. The rotation of the stirring paddle 602 ensures that the fertilizer in the fertilizer box 3 is fully mixed, prevents agglomeration, and ensures the uniformity of fertilization. At the same time, under the action of centrifugal force, the strong magnetic block 703, the connecting rod 702 and the strong magnetic block 703 will gradually stretch the connecting spring 701. Due to clever design considerations, such as the curved end face of the strong magnetic block 703, this design not only reduces direct hard collision with the filter plate 301, but also increases the contact area and improves the cleaning effect. In addition, the elastic characteristics of the spring also play a buffering role, making the contact between the strong magnetic block 703 and the filter plate 301 softer.

[0053] When the strong magnetic block 703 collides slightly with the filter plate 301, the force generated by the collision is sufficient to cause the filter plate 301 to vibrate. This shaking is very effective in cleaning the clogged filter holes on the filter plate 301 because it can shake off impurities or particles attached to the filter holes, thereby maintaining the patency of the filter plate 301.

[0054] In summary, the vibration cleaning component in this embodiment achieves sufficient mixing of the fertilizer in the fertilizer box 3 and effective cleaning of the blocked filter holes of the filter plate 301 through the mixing action of the stirring paddle 602 and the vibration cleaning function of the strong magnetic block 703, thereby effectively improving the efficiency and uniformity of the fertilization operation, while reducing the risk of blockage of the filter plate 301 and improving the reliability and maintenance convenience of the equipment.

[0055] Example 3, refer to Figures 9-12 The auxiliary feeding component includes a plurality of placement buckets 4 fixedly arranged inside the fertilizer box 3, and a leakage groove 401 and a movable magnetic block 8 are provided at the bottom end of the placement bucket 4. The end of the leakage groove 401 passes through the bottom wall of the placement bucket 4, and the movable magnetic block 8 is slidably arranged inside the leakage groove 401. The bottom end of the movable magnetic block 8 is provided with a liquid guide port 801, and the end of the liquid guide port 801 passes through the side wall of the movable magnetic block 8. A baffle 802 for limiting the movable magnetic block 8 is provided on the liquid guide port 801. The leakage groove 401 is used to control the release of additives. The design of the leakage groove 401 allows the additive to flow out under specific conditions and mix with the liquid fertilizer. The main function of the movable magnetic block 8 is to control the opening and closing of the leakage groove 401 by magnetic force.

[0056] Furthermore, the plurality of placement buckets 4 are respectively filled with nitrification inhibitors, powdered biochar and acidifiers. These additives play an important role in improving the soil environment and promoting crop growth. The nitrification inhibitor can be liquid DCD (dicyandiamide), DMPP (3,4-dimethylpyrazole phosphate), etc. The nitrification inhibitor can inhibit the activity of nitrifying bacteria in the soil, thereby slowing down the conversion of ammonium nitrogen to nitrate nitrogen, which helps to reduce the emission of N2O (nitrous oxide) produced by nitrification, and also indirectly helps to reduce ammonia emissions, because the conversion of ammonium nitrogen is slowed down, so that more ammonium nitrogen is retained in the soil, reducing the nitrogen loss through ammonia volatilization.

[0057] Biochar can inhibit the activity of methanogens in the soil and promote the activity of methane-oxidizing bacteria, thereby reducing CH4 emissions. At the same time, biochar can also affect the nitrification and denitrification reactions by adsorbing and fixing nitrogen in the soil, thereby reducing N2O emissions.

[0058] Acidifiers can be aqueous solutions of organic acids (citric acid, acetic acid, etc.) or inorganic acids (phosphoric acid, sulfuric acid, etc.). Acidifiers lower the pH value of the soil and improve the growth environment of crops. After mixing with liquid fertilizers, they can be evenly distributed in the soil with irrigation water or fertilization liquid to achieve the desired acidification effect.

[0059] Through the stirring action of the stirring paddle 602, the nitrification inhibitor, powdered biochar and acidifier can be fully mixed with the liquid fertilizer. The strong magnetic block 703 is located directly below the movable magnetic block 8. The opposite surfaces of the strong magnetic block 703 and the movable magnetic block 8 are set with the same polarity. When the strong magnetic block 703 and the movable magnetic block 8 are facing each other, the magnetic force between the strong magnetic block 703 and the movable magnetic block 8 is greater than the sum of the gravity of the movable magnetic block 8 and the pressure of the liquid fertilizer. When the two are facing each other, due to the principle of like poles repelling each other, a strong repulsive force is generated, which is enough to overcome the gravity of the movable magnetic block 8 and the pressure of the liquid fertilizer, thereby opening the leakage groove 401. At this time, the additive will flow out and mix with the liquid fertilizer.

[0060] It should be noted that the drain slot 401 is initially blocked by the movable magnetic block 8 and is in a closed state (see Figure 11 ), the drain slot 401 is in the open state when the strong magnetic block 703 and the movable magnetic block 8 are facing each other (refer to Figure 12 ).

[0061] In this example,

[0062] Initial state: Figure 11 As shown, in the initial state, the drain groove 401 is blocked by the movable magnetic block 8 and is in a closed state. At this time, the additive in the hopper 4 cannot flow out.

[0063] Activated state: When the dual-axis motor 6 is started, the strong magnetic block 703 rotates along with the transmission shaft 601 to the position directly below the movable magnetic block 8 (as shown in the figure). Figure 7 As shown), due to the strong magnetic repulsion between the two, the movable magnetic block 8 is pushed upward, and the leakage slot 401 is opened (as shown in FIG. Figure 12 As shown), at this time, the additives (such as nitrification inhibitor, powdered biochar and acidifier) ​​placed in the bucket 4 flow into the fertilizer box 3 through the leakage groove 401 and the liquid guide port 801 under the action of gravity and mix with the liquid fertilizer.

[0064] Mixing process: The rotation of the stirring paddle 602 not only ensures the uniform mixing of the liquid fertilizer, but also promotes the full integration of the additive and the liquid fertilizer. This mixing method improves the uniformity and effectiveness of fertilization and can effectively reduce the emission of ammonia and greenhouse gases during the application process of organic fertilizer.

[0065] Closed state: As the strong magnetic block 703 continues to rotate, it gradually moves away from the movable magnetic block 8, the magnetic force decreases, and the movable magnetic block 8 falls back under the action of gravity and the spring reset force, re-blocking the leakage groove 401 and entering the waiting state for the next cycle.

[0066] The auxiliary feeding component achieves precise addition of additives and thorough mixing with liquid fertilizer through ingenious magnetic control and structural design. This design not only improves the accuracy and efficiency of fertilization, but also reduces the risk of waste and environmental pollution.
