Description

Technical Field

[0001] This invention relates to the fields of ecological environment restoration and soil remediation technology, specifically to a tool and method for producing grassland organic fertilizer using livestock urine. Background Technology

[0002] Livestock excretion is a natural fertilization measure for grasslands and an important way for grassland nutrients to be returned. It has great ecological significance for maintaining soil fertility and vegetation productivity. In grazing grassland ecosystems, especially for sensitive natural grassland ecosystems, the return of nutrients from livestock excrement is particularly important.

[0003] my country's animal husbandry has entered a period of rapid development, and the proportion of animal husbandry in the output value of agriculture is also increasing. However, with the transformation of animal husbandry farming models and the continuous expansion of the scale of farming, this has directly led to an increase in the density of excrement from grassland animals such as cattle and sheep, causing seedling burn and other effects in some areas, which has had an adverse impact on the grassland ecological environment.

[0004] In grassland ecosystems, the biogeochemical pathways of nitrogen mainly occur between the atmosphere, soil, plants, animals, and microorganisms, and can be divided into internal and external cycles. External cycles refer to the processes of nitrogen input into and output from the ecosystem; internal cycles refer to the transformation of nitrogen chemical forms and the transfer between different reservoirs in the system.

[0005] The flux of nitrogen in the internal cycle is much greater than that in the external cycle; the nitrogen transformation process in grassland soil is an important component of the internal cycle and is of great significance for revealing the functions of grassland ecosystems and the mechanisms of biogeochemical cycling processes.

[0006] The urine produced by cattle and sheep during grazing is not treated. Livestock urine has a high nitrogen and water content, and the temperature of fresh urine is similar to that of livestock body temperature. When urine seeps into the soil, it can rapidly increase the available nitrogen supply in the soil and change the soil redox environment. Under natural conditions, after livestock urine is excreted into the soil, urea will quickly hydrolyze and lower the soil pH, forming urine spots. Urine spots formed by livestock defecation refer to yellow or green spots on the grassland surface after livestock defecate. Due to the high concentration of nitrogen, phosphorus, potassium and other elements in the urine, these urine spots can cause the following harms to the grassland: Urine spots can destroy the biodiversity of the grassland, allowing some salt-tolerant, alkali-tolerant and drought-tolerant plants to become dominant, while some good forage grasses are squeezed out or suppressed.

[0007] Urine stains can increase the salt content of grasslands, leading to soil salinization. Elements such as nitrogen, phosphorus, and potassium in urine can exchange with cations such as calcium and magnesium in the soil to form soluble salts, reducing soil fertility and aeration.

[0008] Urine stains accelerate the nitrogen cycle in grasslands, promoting ammonia volatilization and nitrous oxide (N2O) emissions. Urea in urine decomposes into ammonia and carbonic acid under the action of microorganisms. Ammonia volatilizes with the wind or reacts with water to form ammonia water, causing air and water pollution. At the same time, nitrates and nitrites in urine are reduced to N2O under denitrification, which is a potent greenhouse gas that has a negative impact on global climate change. Therefore, it is necessary to design a tool and method to make organic fertilizer for grasslands using livestock urine. Summary of the Invention

[0009] The purpose of this invention is to provide a tool and method for producing organic fertilizer for grassland using livestock urine, so as to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a tool for producing organic fertilizer for grassland using livestock urine, comprising a pair of wearable pants, connecting pockets, a core assembly, a wraparound elastic strap, folding lines, an auxiliary fixing assembly, and an adhesive fixing assembly. Connecting pockets are sewn onto both sides of the wearable pants, and a wraparound elastic strap is provided on the connecting pockets. A core assembly is located at the top center of the wearable pants, and a folding line is pressed onto the core assembly. The core assembly consists of an absorbent layer and a fiber layer, with fiber layers at both the top and bottom of the absorbent layer. The wraparound elastic strap has a first Velcro and a second Velcro fastener at each end, which are adhered to each other. One end of the wraparound elastic strap is attached to the top of the back plate in the auxiliary fixing assembly. The auxiliary fixing assembly consists of a back plate, a locking frame, and a limiting element. The back plate is composed of a frame, connecting column, locking groove, locking block, outer support, guide column, locking spring, pull ring, limiting column, top support plate, support spring, tightening cap, and spherical protrusion. A locking frame is installed on one side of the top of the back plate. A connecting column is slidably connected to the locking frame. A locking groove is opened on one side of the connecting column, which connects to one end of the locking block. The locking block is slidably connected to a square groove on one side of the locking frame. The other end of the locking block is fixed to the outer support. Guide columns are slidably connected to symmetrically opened through holes on the outer support. A locking spring is installed between the outer support and the locking frame. The guide column is located inside the locking spring, and one end of the guide column is fixed to the locking frame. The connecting column is fixed to one side of the bottom of the top support plate, and a support spring is installed at the center of the bottom of the top support plate. A tightening cap is fixedly connected to the bottom end of the support spring, and the tightening cap presses tightly against the wrap-around telescopic belt.

[0011] Preferably, the outer bracket is provided with a pull ring.

[0012] Preferably, a limiting post is provided on the other side of the bottom of the top support plate, and the limiting post is slidably connected in the limiting frame.

[0013] Preferably, the limiting frame is fixed to the top of the back plate, and the bottom of the back plate is uniformly provided with spherical protrusions.

[0014] A method for producing organic fertilizer for grassland using livestock urine includes the following steps: Step 1, assembling a wearable structure; Step 2, installing and fixing tools; Step 3, post-composting and adsorption.

[0015] In step one above, the connecting pockets are first symmetrically sewn onto the wearable pants, and the wrap-around elastic band with adhesive fastening components is fixed onto the connecting pockets. Then, the core component is fixed onto the wearable pants to complete the assembly process of the wearable structure.

[0016] In step two above, the back plate of the auxiliary fixing component is placed on the back of the animal. Then, the wrap-around telescopic strap is stretched to cover the animal's hind legs. The first and second Velcro straps are then glued together at the top of the back plate. After the first and second Velcro straps are glued together, the wrap-around telescopic strap is stretched and pressed tightly onto the back plate. Then, the connecting post and the limiting post are slidably connected to the locking frame and the limiting frame, respectively. As the connecting post moves downward, it squeezes the locking block and the outer bracket, causing the outer bracket to pull the locking spring to extend. When the locking groove moves down to be flush with the locking block, the locking block is pressed tightly into the locking groove under the action of the locking spring, thereby fixing the connecting post in the locking frame. After fixing, the top cap is pressed tightly onto the wrap-around telescopic strap under the action of the support spring, preventing the adhesive structure at both ends of the wrap-around telescopic strap from falling off.

[0017] In step three above, the core component absorbs the excreted urine during the livestock feeding process, and then it is periodically removed for composting to make organic fertilizer for the grassland.

[0018] Preferably, in step one, the connecting trouser pocket and the wearable trousers are made of double-layer PHA material. The wearable trousers are approximately elliptical in shape. The length of the wrap-around elastic strap is adjusted according to the size of the livestock. The first Velcro fastener in the adhesive fastening assembly is fixed to the bottom of one end of the wrap-around elastic strap, and the second Velcro fastener is fixed to the top of the other end of the wrap-around elastic strap.

[0019] Preferably, in step one, the fiber layer in the core assembly is composed of cotton stalk fiber and soybean stalk fiber, with the cotton stalk fiber content being 80%, the soybean stalk fiber content being 20%, and the fiber layer thickness being 0.08 cm.

[0020] Preferably, in step one, the absorbent layer in the core component is composed of 95% fluff pulp and 5% anaerobic yeast. The absorbent layer contains micro-sized particle structures. The specific preparation process is as follows: first, anaerobic yeast is cultured for 24 hours under anaerobic conditions, then mixed with starch, and after mixing and stirring, the core raw material is obtained. After shaping and cutting, an absorbent layer with a thickness of 0.16 cm is obtained.

[0021] Preferably, in step one, the core component has a size of 60×30cm. Before use, the long side is used as a fixed boundary, and the core is folded along the fold line with dots. The folding is repeated 10 times to form an accordion-style folded structure. After folding, its shape matches the shape and length of the pants.

[0022] Preferably, in step three, during the use of the tool, the micro-sized particles formed by the absorbent pulp and anaerobic yeast in the core component melt and volatilize upon contact with urine, and the starch carrier easily clumps and disperses, forming a trailing tail with each head. The interaction forces between the starch particles form a loose and porous structure, which forms a fluffy and degradable structure during the later composting process. It is easily blown away by the wind, degrades easily, and does not pollute the environment.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: This tool and method for making organic fertilizer for grassland using livestock urine consists of a flexible connecting structure made of double-layer PHA material wearable pants connected to pants pockets and PLA material wrapping telescopic straps. After the core component is glued and fixed, it adheres to the livestock to absorb the excreted urine. It is lightweight, easy to degrade, environmentally friendly, and does not affect animal health. During the use of the tool, the locking block is pressed tightly into the locking groove under the action of the locking spring, thereby fixing the connecting column in the locking frame. After fixing, the top cap is pressed tightly onto the wrapping telescopic strap under the action of the support spring, preventing the adhesive structure at both ends of the wrapping telescopic strap from falling off. By stretching the locking spring to release the locking block from the locking groove, the top cap can be removed. Then, the mutual adhesion of the adhesive fixing components can be released to remove the tool for composting. The disassembly process is simple, reducing the labor cost of management. During use, the wrapping telescopic straps seal the core component of the accordion-style folding structure, effectively preventing urine leakage and avoiding urine stains caused by urine discharge.

[0035] Please see Figure 8 The present invention provides an embodiment of a method for producing grassland organic fertilizer using livestock urine, comprising the following steps: Step 1, assembling a wearable structure; Step 2, installing and fixing tools; Step 3, subsequent adsorption and composting.

[0036] In step one above, the connecting trouser pocket 2 is first symmetrically sewn onto the wearable trouser 1, and the wrap-around elastic strap 4 containing the adhesive fastening component 7 is fixed to the connecting trouser pocket 2. Then, the core component 3 is fixed to the wearable trouser 1, completing the assembly process of the wearable structure. The connecting trouser pocket 2 and the wearable trouser 1 use double-layer PHA material. The wearable trouser 1 has a centrally approximately elliptical shape. The length of the wrap-around elastic strap 4 is adjusted according to the size of the livestock. The first Velcro 71 in the adhesive fastening component 7 is fixed to the bottom of one end of the wrap-around elastic strap 4, and the second Velcro 72 is fixed to the top of the other end of the wrap-around elastic strap 4. The fiber layer 32 in the core component 3 is composed of cotton stalk fiber and soybean stalk fiber, with the cotton stalk fiber content being 80% and the soybean stalk fiber content being... The straw fiber content is 20%, the fiber layer 32 is 0.08cm thick, and the water-absorbing layer 31 in the core component 3 is composed of 95% fluff pulp and 5% anaerobic yeast. The water-absorbing layer 31 contains micro-sized particle structures. The specific preparation process is as follows: first, anaerobic yeast is cultured for 24 hours under anaerobic conditions, then mixed with starch. After mixing and stirring, the core raw material is obtained. After shaping and cutting, the water-absorbing layer 31 with a thickness of 0.16cm is obtained. The size of the core component 3 is 60×30cm. Before use, the long side is used as the fixed boundary, and the folding is done along the folding line 5. The number of folds is 10. After folding, an accordion-style folded structure is formed. After folding, its shape matches the shape and length of the wearable pants 1.

[0037] In step two above, the back plate 101 of the auxiliary fixing component 6 is placed on the back of the animal. Then, the stretchable wrap-around strap 4 is stretched to cover the animal's hind legs, and the first Velcro 71 and the second Velcro 72 are glued together at the top of the back plate 101. After the first Velcro 71 and the second Velcro 72 are glued together, the stretchable wrap-around strap 4 is pressed tightly onto the back plate 101. Then, the connecting post 104 and the limiting post 111 are slidably connected to the locking frame 102 and the limiting frame 103, respectively. During the downward movement of 104, the locking block 106 and the outer bracket 107 are squeezed, causing the outer bracket 107 to pull the locking spring 109 to extend. When the locking groove 105 moves down to be flush with the locking block 106, the locking block 106 is pressed tightly into the locking groove 105 under the action of the locking spring 109, thereby fixing the connecting column 104 in the locking frame 102. After fixing, the top cap 114 is pressed tightly onto the wrap-around telescopic belt 4 under the action of the support spring 113, preventing the adhesive structure at both ends of the wrap-around telescopic belt 4 from falling off.

[0038] In step three above, during the livestock feeding process, the core component 3 absorbs the excreted urine. During the use of the tool, the micro-sized particles formed by the fluff pulp and anaerobic yeast in the water-absorbing layer 31 of the core component 3 melt and volatilize upon contact with the urine. The starch carrier is easy to clump and disperse, forming a trailing tail with each head. The interaction force between the starch particles forms a loose and porous structure. In the later composting process, a loose and degradable structure is formed, which is easily blown away by the wind, easy to degrade, and does not pollute the environment. Afterwards, it is periodically removed for composting to make grassland organic fertilizer.

[0039] Based on the above, the advantages of the present invention are that, in use, the tool's flexible connection structure, consisting of a double-layer PHA material wearable trouser 1 connected to a trouser pocket 2 and a PLA material wrap-around elastic strap 4, is adhered to the animal's body to absorb excreted urine. It is lightweight, easily degradable, environmentally friendly, and does not affect animal health. During use, the locking block 106 is pressed tightly into the locking groove 105 by the locking spring 109, thereby fixing the connecting post 104 in the locking frame 102, and then tightening the cap 1. 14 is pressed tightly against the wrap-around telescopic belt 4 by the support spring 113 to prevent the adhesive structure at both ends of the wrap-around telescopic belt 4 from falling off. The locking spring 109 is stretched so that the locking block 106 is disengaged from the locking groove 105, and the top cap 114 can be removed. Then the mutual adhesion of the adhesive fixing components 7 can be released, and the tool can be removed for composting. The disassembly process is simple and reduces the labor cost of management. During use, the wrap-around telescopic belt 4 seals the core component 3 of the accordion-style folding structure, effectively preventing urine leakage and avoiding urine stains caused by urine discharge.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
