DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 creative work are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Sheep manure is the excrement excreted by sheep after digesting feed. It is usually in granular form, and the color varies depending on the feed. Fresh sheep manure is dark green or dark brown, and turns gray-brown after drying. The physical and chemical properties of sheep manure make it widely used in agriculture, energy, environmental protection and other fields. Sheep manure is usually in small granular form, about 0.5-1 cm in diameter, with a hard texture and easy to break after drying. Fresh sheep manure has a high water content (about 60%-70%), but the moisture content can be reduced to 10%-20% after drying. Compared with pig manure and chicken manure, sheep manure has a lighter smell and is basically odorless after decomposition. Sheep manure particles are lighter, with a bulk density of about 400-600kg / m 3 , easy to transport and store.

[0036] Sheep manure is rich in organic matter and nutrient elements required by plants, mainly including: Organic matter (25%-35%): Promote the formation of soil aggregate structure and improve the water and fertilizer retention capacity of the soil. Nitrogen (N) (1.5%-3.5%): Promote the growth of plant leaves and improve the photosynthesis efficiency. Phosphorus (P2O5) (0.5%-2.0%): Promote root development and enhance the disease resistance of plants. Potassium (K2O) (1.0%-3.0%): Improve the stress resistance of crops and promote fruit swelling. Trace elements (calcium, magnesium, iron, zinc, etc.): Regulate the physiological functions of plants and prevent nutrient deficiency diseases. In addition, the carbon-nitrogen ratio (C / N) of sheep manure is about 15-25:1, which is suitable for microbial decomposition, and the composting speed is faster than that of cow manure but slower than that of chicken manure.

[0037] Sheep manure has important applications in many fields such as agriculture, energy, environmental protection, and ecological restoration. Its main functions include:

[0038] Agricultural application - high-quality organic fertilizer

[0039] Sheep manure is an efficient and safe organic fertilizer with the following advantages:

[0040] Improve soil structure: The organic matter in sheep manure can promote the formation of soil aggregates, improve soil air permeability and water retention, and is especially suitable for improving compacted soil.

[0041] Provide comprehensive nutrients: Sheep manure contains nitrogen, phosphorus, potassium and various trace elements, which can meet the nutritional needs of crops throughout the growth period and reduce the use of chemical fertilizers.

[0042] Promote microbial activities: Sheep manure is rich in beneficial microorganisms, which can inhibit soil pathogens and reduce soil-borne diseases (such as root rot, wilt disease).

[0043] Improve the quality of agricultural products: The soil where sheep manure is applied for a long time, the fruits and vegetables planted have a better taste, higher sugar content, and lower nitrate content.

[0044] Applicable crops:

[0045] Vegetables (tomatoes, cucumbers, peppers, etc.): Increase yields and reduce deformed fruits.

[0046] Fruit trees (apples, grapes, citrus fruits, etc.): Strengthen the tree vigor and increase the sugar content.

[0047] Field crops (wheat, corn, rice, etc.): Reduce dependence on chemical fertilizers and improve the lodging resistance.

[0048] Energy utilization - biomass fuel and biogas

[0049] Direct combustion: The calorific value of dried sheep manure is about 12-15 MJ / kg, which can be used as fuel for heating or cooking and is widely used in pastoral areas.

[0050] Biogas fermentation: Sheep manure is an excellent biogas raw material with an appropriate carbon-nitrogen ratio and high gas production efficiency (30 - 50 m 3 biogas can be produced per ton of fresh manure), which can be used for power generation or rural gas supply.

[0051] Biochar preparation: Through high-temperature pyrolysis, sheep manure can be converted into biochar for soil improvement or pollutant adsorption.

[0052] Environmental protection application - Pollution treatment

[0053] Wastewater treatment: Sheep manure biochar can adsorb heavy metals (such as lead and cadmium) and organic pollutants (such as pesticide residues) for industrial wastewater purification.

[0054] Soil remediation: Sheep manure compost can remediate heavy metal-contaminated soil, reduce the activity of heavy metals, and promote vegetation recovery.

[0055] Deodorant: Microorganisms in sheep manure can decompose malodorous substances for deodorization in farms or waste treatment plants.

[0056] Ecological agriculture - Recycling

[0057] Earthworm breeding: Sheep manure is an ideal feed for earthworms and can be converted into high-value earthworm manure.

[0058] Black soldier fly breeding: Insects can efficiently decompose sheep manure to produce insect protein and organic fertilizer.

[0059] Integration of planting and breeding: In the "sheep - biogas - vegetable" model, fermented sheep manure is used for vegetable planting to achieve zero-pollution circular agriculture.

[0060] Other applications

[0061] Edible mushroom cultivation: Sheep manure can be used as a cultivation substrate for edible mushrooms such as Agaricus bisporus and Pleurotus ostreatus.

[0062] Traditional architecture: Sheep manure mixed with soil is used to build houses with good heat preservation.

[0063] Medical use: Tibetan and Mongolian medicine have used sheep manure to treat indigestion and skin diseases.

[0064] Treatment and usage methods of sheep manure

[0065] Traditional treatment methods

[0066] Natural composting: Stack sheep manure for 3 - 6 months and rely on natural decomposition by microorganisms, which is suitable for small farmers.

[0067] Sun drying: Spread it out to dry and then store it to reduce volume for easy transportation.

[0068] Modern composting technology

[0069] Aerobic composting (recommended): Adjust the moisture content (50%-60%) and carbon-nitrogen ratio (25:1), turn the pile regularly, and it can be matured in 20-30 days.

[0070] Anaerobic fermentation: Used for biogas production, the fermentation tank needs to be sealed, and the temperature is controlled at 35-55°C.

[0071] Biological bacterial agents to accelerate composting: Add EM bacteria, Bacillus subtilis, etc., and shorten the composting time to 15 days.

[0072] Precautions for safe use

[0073] Fully mature: Unmatured sheep manure may burn the roots and carry pathogens (such as Escherichia coli).

[0074] Reasonable dosage: Generally apply 1-2 tons per mu, and excessive application may lead to salt accumulation.

[0075] Combined use: Mixing with straw and wood chips can improve air permeability; combining with chemical fertilizers can improve fertilizer efficiency.

[0076] Sheep manure is not only a high-quality organic fertilizer but also has wide applications in the fields of energy, environmental protection, ecological agriculture, etc. With the development of green agriculture and circular economy, the resource utilization of sheep manure will be more and more emphasized. Reasonable utilization of sheep manure can not only reduce environmental pollution but also improve agricultural sustainability, achieving a win-win situation for both economy and ecology.

[0077] Refer to Figures 1 to 6 As shown, the present invention provides an automatic sheep manure conveying device for a three-dimensional sheep house, including a breeding platform 1, which is arranged on the ground in the sheep house, and the breeding platform 1 is used for breeding sheep;

[0078] A surrounding component, which is arranged on the top wall of the sheep house. The surrounding component corresponds to the breeding platform 1 up and down and has a gap with the breeding platform 1. The surrounding component is used to block the sheep on the breeding platform 1;

[0079] A sheep manure cleaning component, which is arranged in the gap between the breeding platform 1 and the surrounding component. The sheep manure cleaning component is used to clean the sheep manure on the breeding platform 1;

[0080] A sheep manure transfer component, which is arranged below one end of the breeding platform 1. The sheep manure transfer component is used to transfer the cleaned sheep manure;

[0081] A sheep manure screening component, which is arranged at the discharging end of the sheep manure transfer component. The sheep manure screening component is used to screen oval sheep manure and non-oval sheep manure;

[0082] A solid-liquid separation component, which is arranged below one end of the sheep manure screening component. The solid-liquid separation component is used to separate oval sheep manure and sheep urine;

[0083] The second collection bin 28 is arranged below the other end of the sheep manure screening assembly. The second collection bin 28 is used for collecting non-elliptical sheep manure.

[0084] Furthermore, the sheep manure cleaning assembly includes four second support legs 5 which are respectively arranged around the breeding platform 1. The top of one of the second support legs 5 is fixedly connected with a first motor 6, and the tops of the other three second support legs 5 are all fixedly connected with fixed seats 8. One end of a lead screw 7 is fixedly connected with the output shaft of the first motor 6, and the other end of the lead screw 7 is rotatably connected with one of the fixed seats 8. A smooth rod 39 is fixedly connected between the other two fixed seats 8. The smooth rod 39 is parallel to the lead screw 7. A slider 9 is threadedly connected to the lead screw 7, and another slider 9 is slidably connected to the smooth rod 39. A first scraping plate 10 is fixedly connected between the two sliders 9. The bottom end of the first scraping plate 10 is in sliding contact with the top end of the breeding platform 1.

[0085] Furthermore, the first scraping plate 10 is V-shaped, and the opening of the first scraping plate 10 faces the sheep manure transfer assembly.

[0086] After a certain amount of sheep manure accumulates on the breeding platform 1, the first motor 6 is started. The first motor 6 drives the lead screw 7 to rotate. During the rotation of the lead screw 7, the first scraping plate 10 is driven to move through the slider 9. During the movement of the first scraping plate 10, the sheep manure and urine on the breeding platform 1 are pushed forward. Since the bottom end of the first scraping plate 10 is in sliding contact with the top end of the breeding platform 1, the first scraping plate 10 can clean and push all the sheep manure and urine on the top end of the breeding platform 1 onto the sheep manure transfer assembly. At the same time, because the first scraping plate 10 is set to be V-shaped and the opening faces the sheep manure transfer assembly, the sheep manure and urine can be concentrated in the middle of the first scraping plate 10 and all fall onto the sheep manure transfer assembly during the process of pushing.

[0087] Furthermore, the sheep manure transfer assembly includes four third support legs 11. A driving roller 12 is rotatably connected between the tops of two of the third support legs 11. A driven roller 13 is rotatably connected between the tops of the other two third support legs 11. The driven roller 13 is parallel to the driving roller 12 and is located below the end of the breeding platform 1. A conveyor belt 14 is jointly driven on the outer sides of the driving roller 12 and the driven roller 13. One end of the driving roller 12 is fixedly connected with the output shaft of a second motor 29. The second motor 29 is fixedly connected with the third support leg 11. A cleaning part is fixedly connected to the tops of the two third support legs 11 where the driving roller 12 is rotatably connected. The cleaning part is in sliding contact with the outer surface of the conveyor belt 14.

[0088] Furthermore, the cleaning part includes two connecting rods 15, which correspond to the third supporting legs 11 one by one and are fixedly connected to the top of the side wall of the third supporting leg 11. The two connecting rods 15 are commonly fixedly connected with a second scraper 16. The second scraper 16 is vertically arranged and the top end is in sliding contact with the outer surface of the conveyor belt 14. The bottom end of the second scraper 16 is located above the sheep dung screening assembly.

[0089] After the sheep dung and urine fall onto the conveyor belt 14, the second motor 29 drives the conveyor belt 14 to rotate through the active roller 12, and transfers the sheep dung and urine to the sheep dung screening assembly. When the conveyor belt 14 rotates to the position of the second scraper 16, the second scraper 16 scrapes the urine and relatively thin sheep dung remaining on the surface of the conveyor belt 14 into the sheep dung screening assembly to ensure the cleanliness of the surface of the conveyor belt 14.

[0090] Furthermore, the sheep dung screening assembly includes a transfer box 17, which is arranged below the unloading end of the sheep dung transfer assembly. The bottoms of the two opposite outer walls of the transfer box 17 near one end of the sheep dung transfer assembly are respectively fixedly connected with a first rotating shaft 18, the first rotating shaft 18 is rotatably connected to one end of a fourth supporting leg 19, and the other end of the fourth supporting leg 19 is fixedly connected to the ground of the sheep shed, and the bottoms of the two opposite outer walls of the other end of the transfer box 17 are respectively fixedly connected with a second rotating shaft 20, the second rotating shaft 20 is rotatably connected to one end of a telescopic rod 21, and the other end of the telescopic rod 21 is rotatably connected to a third rotating shaft 22, the third rotating shaft 22 is fixedly connected to a support seat 23, and the support seat 23 is fixedly connected to the ground of the sheep shed, and a sheep dung screening part is arranged in the transfer box 17.

[0091] Furthermore, the sheep dung screening part includes a third motor 30, a movable plate 31, and a connecting shaft 34. The third motor 30 is fixedly connected to the bottom of an outer wall of the transfer box 17. The output shaft of the third motor 30 is fixedly connected to an embedded rotating shaft. The embedded rotating shaft is rotatably arranged in the bottom wall of the transfer box 17. A plurality of rotating baffles 32 are fixedly connected to the embedded rotating shaft. The plurality of rotating baffles 32 are arranged at equal intervals along the length direction of the embedded rotating shaft. The movable plate 31 is arranged at one end of the transfer box 17 close to the sheep dung transfer assembly and its top end is rotatably connected to the top of the side wall of the transfer box 17. The connecting shaft 34 is fixedly arranged at the top of the side wall at the other end of the transfer box 17. The connecting shaft 34 is rotatably connected to a plurality of free baffles 35. The plurality of free baffles 35 are arranged at equal intervals along the length direction of the connecting shaft 34. A plurality of clearance holes 33 are opened at one end of the bottom wall of the transfer box 17 close to the connecting shaft 34. The rotating baffles 32 and the free baffles 35 are both located in the clearance holes 33.

[0092] Normal sheep manure is approximately oval in shape, while abnormal sheep manure is thicker in block or thinner in fluid. When all the sheep manure and urine fall into the transfer box 17, they are located between the movable plate 31 and the rotating baffle 32. At this time, the telescopic rod 21 is continuously extended and shortened, so that the transfer box 17 is continuously changed in the horizontal direction and the direction of inclination toward the solid-liquid separation component, so that the normal oval sheep manure passes through the gap between the two rotating baffles 32 to reach the position of the clearance hole 33, and finally falls into the solid-liquid separation component through the clearance hole 33. At the same time, the sheep's urine and thinner feces also flow along the side wall of the yield hole 33 and finally drip into the solid-liquid separation component, while the thicker sheep feces stays between the movable plate 31 and the rotating baffle 32 due to the blocking effect of the rotating baffle 32. When a certain amount of thicker sheep feces accumulates between the movable plate 31 and the rotating baffle 32 and affects the screening of the sheep feces, the telescopic rod 21 continues to extend, causing the transfer box 17 to tilt toward the second collection box 28, and the thicker sheep feces automatically rolls down, pushes open the rotating baffle 32, and falls into the second collection box 28 to be collected.

[0093] The free baffle 35 rotatably arranged on the connecting shaft 34 can block the normal sheep manure rolling down, and prevent it from flying out of the solid-liquid separation component due to excessive speed during the rolling process.

[0094] The third motor 30 can adjust the tilt angle of the rotating baffle 32 so that the rotating baffle 32 cooperates with the free baffle 35 to slow down the rolling speed of the sheep manure.

[0095] Furthermore, the solid-liquid separation component includes a first collecting box 24, which is arranged below one end of the sheep dung screening component away from the second collecting box 28. The bottoms of the two opposite inner side walls of the first collecting box 24 are respectively fixedly connected with support plates 37, and the tops of the two support plates 37 are jointly provided with a filter box 25. The filter box 25 is movably arranged in the first collecting box 24, and the tops of the two opposite side walls of the filter box 25 are respectively fixedly connected with handles 26. The bottom wall of the filter box 25 is provided with a plurality of evenly arranged leakage holes 36, and a space is left between the bottom end of the filter box 25 and the inner bottom wall of the first collecting box 24, and a drainage part is provided in the space.

[0096] Furthermore, the drainage part includes a drainage pump 38 , which is disposed at the bottom end of the first collecting box 24 . The drainage pump 38 is fixedly connected to one end of the discharge pipe 27 , and the other end of the discharge pipe 27 is located outside the first collecting box 24 .

[0097] After normal sheep manure, thinner sheep manure, and sheep urine all fall into the filter box 25, through the filtering effect of the liquid leakage holes 36 in the bottom wall of the filter box 25, the normal sheep manure stays in the filter box 25, and the other two drip into the first collection box 24 through the liquid leakage holes 36. When the drainage pump 38 works, the urine and thinner sheep manure are discharged from the first collection box 24 through the discharge pipe 27. When there is a large amount of normal sheep manure accumulated in the filter box 25, the staff lift the filter box 25 out of the first collection box 24 through the two handles 26, pour out the sheep manure in the filter box 25, and then put it back into the first collection box 24 to continue the solid-liquid separation.

[0098] Further, the enclosure assembly includes a fence 3. The shape of the fence 3 is adapted to the breeding platform 1. The fence 3 is fixedly connected to the top wall of the sheep house through a number of hanging rods 4. There is a gap between the bottom end of the fence 3 and the breeding platform 1.
