[0019] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0020] As Figures 1 to 8 shown, the present invention discloses an environment-friendly poultry manure treatment system, including a poultry house 1, a collection mechanism 2, a separation device 3 and a treatment mechanism. Among them, the poultry house 1 is used to accommodate poultry. The bottom of the poultry house 1 is provided with a bottom plate 12 and a faecal leakage plate 11 with a hole structure at intervals. The bottom plate 12 is located below the faecal leakage plate 11 and forms a cavity 13 with the faecal leakage plate 11. The cavity 13 is used to collect manure to prevent external leakage and pollute the breeding environment. The structure of the faecal leakage plate 11 can be a square structure or a circular structure, which can be adaptively set according to requirements. In one example, the faecal leakage plate 11 is composed of a plurality of square structures spliced together. The faecal leakage plate 11 with a hole structure is used to enable manure to pass through the holes and fall into the cavity 13 below when poultry defecates. In addition, the faecal leakage plate 11 can separate poultry from manure, ensure the cleanliness of the poultry environment, and prevent poultry from falling and causing life-threatening.

[0021] The collection mechanism 2 is located within the cavity 13. The collection mechanism 2 is used for collecting and transporting feces. The collection mechanism 2 includes a scraper 22 connected to the poultry house 1 through a moving mechanism 21. The moving mechanism 21 can drive the scraper to reciprocate along a preset trajectory. The moving mechanism 21 can be a gear mechanism, a lead screw motor drive structure, a chain mechanism, etc., as long as it can move the scraper 22, and can be adaptively set according to requirements. The scraper 22 is mounted on the moving mechanism 21 through a support structure. The scraper 22 has an arc-shaped structure. The arc-shaped scraper 22 can evenly disperse the force for scraping feces, thereby improving the feces collection efficiency. During use, the scraper 22 is in close contact with the feces leakage plate 11 and the bottom plate 12. The moving mechanism 21 is driven to drive the scraper 22 to move along the length direction of the poultry house 1, so as to push the collected feces to the required position.

[0022] Continue to refer to Figures 1 to 8 , the separation device 3 is located outside the poultry house 1. The separation device 3 is used for solid-liquid separation of the collected feces. The separation device 3 includes an L-shaped connecting piece 31 and a separator 32. One end of the connecting piece 31 is connected to the poultry house 1, and the other end is connected to the separator 32, so that the cavity 13 is internally connected to the separator 32 through the connecting piece 31, thereby realizing the sealed transportation of feces from the cavity 13 to the separator 32, preventing feces leakage or odor diffusion, causing environmental pollution and the hygiene and safety of poultry. The separator 32 effectively separates the liquid (such as sewage) and solid (such as fecal residue) in the feces, so as to facilitate subsequent separate treatment or resource utilization. A treatment mechanism is connected to one side of the separator 32. The treatment mechanism is used for treating the separated feces. The treatment mechanism can be a fermentation module, a purification module, a recovery module, etc., so as to improve the environmental protection efficiency and resource utilization rate.

[0023] During use, poultry live in the poultry house 1. The feces of the poultry fall onto the bottom plate 12 through the feces leakage plate 11. The operator drives the moving mechanism 21 to drive the scraper 22 to reciprocate along the length direction of the poultry house 1 (such as Figure 1 the x direction shown in the figure), so as to scrape the feces into the separator 32 through the connecting piece 31 for solid-liquid separation. Both the solid part and the liquid part are adaptively treated by the treatment mechanism, so as to prevent feces pollution and resource utilization.

[0024] In this application, through the combination and integrated setting of the collection mechanism, the separation device and the treatment mechanism, the automatic collection and transportation of feces are realized, the frequency of manual cleaning is reduced, and by driving the moving mechanism to drive the scraper to move, the L-shaped connecting pieces are connected to the poultry house and the separator, and the closed solid-liquid separation and pollution isolation can be realized, preventing secondary pollution and odor diffusion, so as to have efficient resource utilization and prepare stable fertilizers and energy, effectively protecting the environment.

[0025] In some embodiments, as Figure 1 shown, along the width direction of the pen 1 (such as Figure 1 the y direction shown), the length of the connecting member 31 is greater than the length dimension of the scraper 22, so that the scraper 22 can cover a wider area within the entire moving range, and the connecting member 31 can effectively limit the position of feces transportation, thereby ensuring that the feces accurately fall into the separator 32 for efficient solid-liquid separation work.

[0026] In one example, the moving mechanism 21 adopts a gear mechanism. Among them, the moving mechanism 21 includes a sector gear 211 and a rack 212 mounted on the gear 210. There are multiple gears 210. The sector gear 211 and the rack 212 are both mounted on each gear 210, and there are two sector gears 211. The rack 212 is located between the two sector gears 211. The scraper 22 is mounted on the rack 212 through a support structure. In one example, the scraper 22 can be adjusted in the circumferential angle relative to the rack 212 along the support structure, so as to achieve precise and efficient collection, reduce the cost of manual intervention, improve the overall collection efficiency, and improve the sanitary environment of the breeding pen. At the same time, the scraper 22 drives the sector gear 211 and the rack 212 engaged therewith to move linearly along the rotation of the gear 210, so that the scraper 22 approaches or moves away from the separation device 3. That is, when the feces in the cavity 13 need to be cleaned, the angle of the scraper 22 is adjusted so that the bottom of the scraper 22 is closely attached to the bottom plate 12, and the sector gear 211 is driven to drive the scraper 22 on the rack 212 to move linearly along the length direction of the pen 1 (such as Figure 5 the direction indicated by the x arrow shown), so that the scraper 22 approaches the separator 32 and scrapes the feces into the separator 32. After the cleaning is completed, the angle of the scraper 22 is adjusted again so that the scraper 22 moves away from the bottom plate 12. At the same time, the sector gear 211 is driven to drive the scraper 22 on the rack 212 to move linearly along the length direction of the pen 1 (such as Figure 5 the opposite direction of the x arrow shown), so that the scraper 22 moves away from the separator 32, thereby moving the scraper 22 to its original position to avoid affecting normal work. When there is still residual feces on the bottom plate 12, clean the feces on the bottom plate 12 again according to the above steps, thereby improving flexibility and thoroughness.

[0027] In some embodiments, as Figures 1 to 5 shown, the scraper 22 is composed of a flexible scraping part 220 and a fixing part 221. Along the height direction of the scraper 22 (such as Figure 5In the z - direction shown, the scraping parts 220 are located on both sides of the fixing part 221. The scraping parts 220 are made of flexible materials, such as rubber, plastic, and fiber materials, etc. In one example, the scraping part 229 is made of silica gel and is connected to the fixing part 221 through a spring. The silica gel material has good flexibility and wear resistance, can effectively fit the irregular surfaces. The spring provides elastic support, enabling the scraping part 229 to adapt to the surface undulations, and form a good fit with the top surface of the bottom plate 12 and the bottom surface of the feces - leakage plate 11 during the scraping process. This can ensure the cleaning of the feces on the surfaces of the bottom plate 12 and the feces - leakage plate 11 while avoiding surface damage and wear, enhancing the durability. The fixing part 221 is used to stabilize the overall structure of the scraper 22 and is connected to the rack 212 on the moving mechanism 21 through a support structure, realizing the cleaning and conveying of feces and improving the stable operation of feces collection.

[0028] In some embodiments, such as Figure 1 and Figure 6 shown, the separator 32 has a spiral shaft 321, a discharge port 322, and a liquid - discharge port 323. The discharge port 322 is located on one side of the separator 32, and the liquid - discharge port 323 is located at the bottom of the separator 32. The diameter of the spiral shaft 321 gradually increases along the feces - conveying direction (such as the y - direction shown in Figure 1 ), which can effectively compress and extrude the feces. During the feces - conveying process, as the diameter of the spiral shaft 321 increases, the pushing force on the feces can be gradually enhanced, thus effectively pushing the feces to flow along the conveying direction. By continuously increasing the pressure, the solid part and the liquid part in the feces can be more thoroughly separated. The surface of the spiral shaft 321 is provided with spiral grooves, which can increase the friction between the spiral shaft 321 and the feces, making the feces move more smoothly on the axial surface of the spiral shaft 321, and effectively enhancing the grasping force on the feces, helping to separate the solid part in the feces from the liquid, pushing the solid part to the discharge port 322, while the liquid part flows out along the liquid - discharge port 323, making the solid part of the feces drier, facilitating subsequent composting, and making the liquid part of the feces purer, which is beneficial for subsequent treatments such as fermentation. At the same time, it can improve the processing efficiency and processing capacity of the separator 32, making the solid - liquid separation process of feces more efficient and uniform.

[0029] In some embodiments, such as Figure 1 and Figure 6As shown, the drain port 323 is provided with a screen device 324. The screen device 324 can further improve the separation effect and the precise control of the drainage process. The screen device 324 is composed of multiple small units that can be independently opened and closed. Each small unit is equipped with a separate control mechanism, which can automatically adjust the opening or closing according to the characteristics of the liquid and the separation requirements. In one example, the control mechanism includes a pressure sensor 325 and a controller 326. Each unit is connected to the pressure sensor 325, and the pressure sensor 325 is electrically connected to the controller 326 of the screen hole size of the control unit. During use, the pressure sensor 325 can monitor the pressure borne by each unit in real time and transmit the detected pressure signal to the controller 326. The controller 326 can monitor the change of the liquid flow rate in real time and whether there is blockage or excessive accumulation in each unit. When the pressure in a certain area is too high, the corresponding unit automatically enlarges the screen hole size to accelerate the liquid outflow and balance the pressure, preventing the screen from being blocked. After the pressure returns to normal, the unit resumes its original aperture to ensure the separation accuracy, so as to ensure that the screen device 324 at the drain port 323 always maintains the best state, effectively improving the adaptability and stability of the solid-liquid separation module, enhancing the solid-liquid separation efficiency and quality, and reducing equipment failures and maintenance frequencies.

[0030] In some embodiments, such as Figure 1 、 Figure 7 and Figure 8 As shown, the processing mechanism includes a composting device 41 and a fermentation tank 42. The discharge port 322 is connected to the composting device 41 through a first pipe fitting 5. The composting device 41 is used to process the solid part discharged from the discharge port 322 of the separator 32. The solid part contains organic matter that can be converted into organic fertilizer for use in scenarios such as agriculture or horticulture. The composting device 41 can provide appropriate temperature, humidity, and oxygen supply to promote the rapid decomposition of microorganisms, thereby accelerating the degradation process of organic matter. The drain port 323 is connected to the fermentation tank 42 through a second pipe fitting 6. The fermentation tank 42 is a closed reaction vessel used for biological fermentation treatment of the liquid part, decomposing the organic matter therein and removing the harmful components. It can gradually convert the organic matter in the liquid part into useful products (such as biogas, fertilizer solution, etc.) under controlled temperature and humidity conditions, thereby rationally utilizing feces and reducing environmental pollution.

[0031] In some embodiments, continue to refer to Figure 1 、 Figure 7 and Figure 8, the interior of the composting device 41 is provided with a multi-layer structure, and each layer structure is connected by a partition plate 410 with an adjustable angle. The partition plate 410 with an adjustable angle facilitates the transfer of the solid part of the feces between different hierarchical structures to achieve layered composting. At the same time, an opening is provided on the side wall of the composting device 41, and the operator can use a turning machine to turn the solid part at the bottom to the top, and so on to achieve the turning of the compost. At the same time, by adjusting the partition plate 410, the solid parts between each layer can be evenly structured with oxygen supply and the action of microorganisms, thereby accelerating the decomposition process.

[0032] The composting device 41 further includes an air-flow guiding ventilation device 411. The ventilation device 411 is at the bottom of the composting device 41 and can effectively guide the air to be evenly distributed in each layer structure inside the composting device 41, so that the air circulates between each layer structure, ensuring that each layer of solid parts can obtain sufficient oxygen supply, thereby accelerating the degradation process of the solid parts, improving the quality of the final compost solid parts, reducing the impact on the environment at the same time, and making the composting process more efficient and environmentally friendly.

[0033] In some embodiments, such as Figure 1 and Figure 8 shown, the fermentation tank 42 is composed of an inner layer 420 and an outer layer 421. The inner layer 420 is provided with stirring blades 422. The blades 422 are in a spiral structure. The spiral blades 422 can continuously turn and stir the liquid part in the fermentation tank 42 by rotation, so that the liquid part can fully contact with the microorganisms and oxygen in the fermentation tank 42, thereby promoting the degradation process of organic matter. The rotation direction of the blades 422 is opposite to the flow direction of the liquid part, ensuring that the liquid part can be evenly heated and affected by bacteria during the fermentation process, thereby accelerating the fermentation reaction and improving the treatment efficiency. The outer layer 421 is provided with a heating device 423. The heating device 423 is located between the inner layer 420 and the outer layer 421. The heating device 423 provides heat for the fermentation tank 42. In one example, the heating device 423 generates heat through a resistance wire, and the temperature of the resistance wire is between 40°C and 70°C, which is beneficial to the activity of microorganisms in the liquid part and the degradation of organic matter, and can accelerate the fermentation rate.

[0034] A biogas collection device 7 is also provided on one side of the fermentation tank 42. The biogas collection device 7 is used to collect the biogas generated during the fermentation process. The biogas collection device 7 is connected to the top of the fermentation tank 42 through a pipeline 9. During use, the fermentation tank 42 effectively treats the liquid part and reasonably utilizes the generated biogas, thereby improving the resource utilization efficiency.

[0035] In some embodiments, such as Figure 1As shown in the figure, it further includes a wastewater treatment mechanism 8 which is used to treat the wastewater generated during use, and the wastewater treatment mechanism 8 can be connected to both the composting equipment 41 and the fermentation tank 42. In one example, the wastewater treatment mechanism is connected to the fermentation tank 42. During the treatment process of the fermentation tank 42, a certain amount of moisture will be generated in the liquid part, and these moisture are transported through the pipeline 9 to the wastewater treatment mechanism 8 for treatment. A filter is provided inside the wastewater treatment mechanism 8, so as to remove solid particles and suspended substances, and facilitate subsequent effective utilization (for example, the treated wastewater is used for agricultural irrigation and provides valuable fertilizers for agriculture and horticulture, etc.). In another example, the wastewater treatment mechanism 8 is connected to the composting equipment 41, and its function is similar to the wastewater treatment in the composting equipment 41. For this, no more details are given in this application.

[0036] In some embodiments, as Figure 1 shown in the figure, it further includes an intelligent control module 10. The intelligent control module 10 is electrically connected to the collection mechanism 2, the separation device 3 and the treatment mechanism. The intelligent control module 10 can automatically adjust the operating parameters of each mechanism. For example, the intelligent control module 10 adjusts the working state of the separation device 3, controls the movement and separation speed of the scraper 22, so as to improve the efficiency of feces cleaning and ensure the optimization of the subsequent solid-liquid separation effect. The intelligent control module 10 adjusts the temperature, humidity and the working state of the ventilation device 411 inside the composting equipment 41 to ensure the optimal microbial activity during the composting process and promote the degradation of organic waste. Another example is that the intelligent control module 10 controls the working state of the heating device 423 and the stirring paddle 422 in the fermentation tank 42 to ensure the fermentation temperature and mixing effect, so that the liquid part is fully fermented. The intelligent control module 10 not only makes the whole treatment system automated and intelligent, but also can make accurate decisions based on real-time data, thereby improving the overall treatment efficiency, reducing the need for manual operation and intervention at the same time, enhancing the stability and response speed of the system, and reducing the secondary pollution of waste, realizing true green environmental protection and resource utilization.

[0037] The working principle of an environment-friendly poultry manure treatment system in this application is as follows: As Figures 1 to 8 shown in the figure, first of all, poultry manure falls from the manure leakage plate 11 into the cavity 13. The moving mechanism 21 on the bottom plate 12 drives the scraper 22 to move. The scraper 22 scrapes the manure on the bottom plate 12 and the manure leakage plate 11 and moves towards the separation device 3, so that the manure falls into the separator 32 through the connecting piece 31. The variable-diameter spiral shaft 321 in the separator 32 can separate the solid part and the liquid part in the manure. It should be noted that the solid part of the manure includes manure particles, undecomposed organic matter, etc., while the liquid part is sewage rich in moisture and organic matter.

[0038] After that, the solid part of the feces enters the composting equipment 41 through the discharge port 322 and the first pipe fitting 5. The composting equipment 41 has a multi-layer structure with adjustable partitions 410 between each layer to ensure that the solid part ferments under suitable temperature and humidity conditions. The ventilation device 411 during the composting process ensures good ventilation, promotes microbial activity, and accelerates feces decomposition. The liquid part of the feces enters the fermentation tank 42 through the liquid discharge port 323 and the second pipe fitting 6, and in a high-temperature and high-humidity environment, through the spiral agitation of the paddle 422 and the heating of the heating device 423, the organic matter is further decomposed. During this period, the biogas generated by fermentation flows into the biogas collection device 7 through the pipeline 9 for collection and is used for power generation, heating or other resource utilization of energy uses. Moreover, the wastewater generated in the fermentation tank 42 or the composting equipment 41 flows into the wastewater treatment mechanism 8 for cleaning and recycling, removing pollutants such as suspended solids, organic matter, nitrogen and phosphorus in the wastewater, ensuring that the wastewater meets the discharge standard, and the treated wastewater can be used for agricultural irrigation or further recycling.

[0039] Finally, the entire system is automatically adjusted through the intelligent control module 10, real-time monitoring various data (such as temperature and humidity, flow rate, air pressure, etc.), ensuring that the operation of each link is precise and stable, and alarming or automatically adjusting in case of failure to ensure the efficient operation of the system.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the claims of the present invention.
