Description

Technical Field

[0001] This invention relates to the field of livestock manure treatment technology, specifically to a large-scale pig farm manure removal device and method. Background Technology

[0002] With the rapid development of animal husbandry towards large-scale and intensive operations, the scale of pig farming is constantly expanding, leading to a significant increase in the amount of manure generated by pig farms, posing a huge challenge to manure treatment. As the first crucial step in manure treatment, the technology of manure removal directly determines the efficiency of subsequent manure reduction, harmless treatment, and resource utilization. It also has a vital impact on the hygiene of the farming environment, the health of the pig herd, and the surrounding ecological environment. Under modern large-scale farming models, traditional manure removal methods can no longer meet the demands for efficient, environmentally friendly, and low-consumption production. Optimizing and upgrading manure removal technology has become an urgent need to solve the manure treatment problems in the farming process.

[0003] There are various existing manure cleaning processes, including mechanical dry manure cleaning processes such as mechanical flat scraping and mechanical V-shaped scraping. Mechanical flat scraping uses scrapers installed in a dedicated manure channel, which are moved by a traction device to clean the manure. Mechanical V-shaped scraping uses a V-shaped trench, with scrapers moving along the trench walls to collect the manure. Soaking manure involves storing manure in a manure storage tank at the bottom of the pigsty, allowing for temporary storage through natural fermentation and soaking. Fermentation bed manure cleaning relies on bedding material, utilizing microbial fermentation to decompose manure; regular turning of the bedding is necessary to ensure fermentation effectiveness. Water flushing manure cleaning involves flushing the pigsty with large amounts of water, flushing the manure into a collection tank; manual dry manure cleaning mainly relies on manual sweeping to collect manure.

[0004] In actual farming scenarios, existing manure cleaning processes have many problems. For example, the mechanical V-shaped scraper used in some large-scale pig farms is difficult to install and prone to incomplete cleaning when dealing with large volumes of manure, leading to a deterioration of the sty's hygiene. This is because its structural design is not fully adapted to the need for rapid cleaning of large amounts of manure, and the equipment is easily damaged in humid and corrosive environments; scrapers and wire ropes are often corroded or worn, increasing maintenance difficulty and costs. The soaking process, used by most large-scale pig farms, results in manure stagnation in the storage tank for extended periods. In the closed environment during winter, this produces large amounts of harmful gases such as hydrogen sulfide and ammonia, endangering the health of pigs and farm workers. This is due to the inability to effectively control the anaerobic fermentation process of manure, and prolonged soaking also increases the cost of subsequent solid-liquid separation and pollutant treatment. Manual dry manure cleaning in small-scale pig farms or individual farmers is labor-intensive and inefficient; long-term manure accumulation easily breeds bacteria and produces foul odors, clearly failing to meet the high-efficiency requirements of large-scale farming. These problems highlight the shortcomings of existing processes in terms of adaptability, environmental friendliness, and economy. Therefore, the present invention provides a large-scale pig farm manure removal device and method to overcome the shortcomings of the prior art. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-10 This invention provides a large-scale pig farm manure removal device, comprising: a sewage discharge area 1 located below the pigsty, with a grating plate on top, allowing pig manure to fall through the gaps in the grating plate. Multiple V-shaped manure channels 4 are formed at the top of the sewage discharge area 1, with the angle between the two slopes ranging from 75° to 90°. The surface of the V-shaped manure channels 4 is a concrete structure, treated with a concrete sealant during construction to make the slopes smoother, accelerating the fall of manure and reducing stickiness. A bottom channel 5 is formed at the lowest point of the V-shaped manure channels 4, and a middle channel 6 is formed in the middle of the inner side of the V-shaped manure channels 4. The top of the guide pipes 218 in both the bottom channel 5 and the middle channel 6 is cut off by one-third to form a notch, facilitating the fall of manure into the guide pipes 218. Two sewage discharge troughs 7 are formed at the top of the sewage discharge area 1, located at both ends of the V-shaped manure channels 4. Multiple sewage outlets 8 are provided inside the sewage discharge troughs 7 for discharging wastewater generated during cleaning.

[0039] Multiple scraping mechanisms 2 are respectively located inside the V-shaped manure ditch 4 and span across the two sewage troughs 7 and installed on the top of the sewage area 1. They are used to scrape pig manure in the V-shaped manure ditch 4. The scraping mechanism 2 includes a drive assembly and a scraping assembly. The scraping assembly includes two channel pipes 214 and two guide pipes 218. The two guide pipes 218 are respectively embedded in the bottom trough 5 and the middle trough 6.

[0040] Multiple cleaning mechanisms 3 are located above the drain trough 7 and in contact with the scraping mechanism 2. They are mounted on the inner wall of the drain trough 7 via brackets. The drive assembly includes a drive housing 201, which is fixedly connected to the top of the drain area 1. One end of a channel pipe 214 is welded to one side of the drive housing 201 and communicates with the interior of the drive housing 201. Multiple scraping discs 216 and multiple connecting rings 217 are slidably connected inside the channel pipe 214. Each scraping disc 216 is composed of two conical cusps, and the two scraping discs 216 are connected by connecting rings 217. Multiple scraper discs 216 and multiple connecting rings 217 are connected to form a ring. The ring hinge in the multiple scraper mechanisms 2 can form a closed loop through two lowest guide tubes 218 or through two middle guide tubes 218. The middle and lowest guide tubes 218 are both made of PE material. The diameter of the middle guide tube 218 is 110 mm, and the diameter of the lowest guide tube 218 is 160 mm. The wall thickness of both is 3 mm. The diameter of the thickest part of the scraper disc 216 passing through the two positions is about 5 mm smaller than the diameter of the contacting guide tube 218.

[0041] The outer side of the scraper disc 216 is slidably connected to the inner side of the guide tube 218. A corner device 215 is installed at the bend of the channel tube 214. A rotating wheel is installed inside the corner device 215, and the scraper disc 216 contacts the rotating wheel. The corner device 215 is used to assist the hinge formed by the scraper disc 216 and the connecting ring 217 to rotate 90 degrees. A servo motor 202 is installed inside the drive box 201. After the servo motor 202 is started, it can drive the drive wheel 203 to rotate. The output end of the servo motor 202 is fixedly connected to the drive wheel 203. Multiple shift forks 204 are fixedly connected to the outer periphery of the drive wheel 203. The shift forks 204 can move the scraper disc 216 when the drive wheel 203 rotates. The outer side of the shift fork 204 is provided with a V-shaped groove 205. The inner side of the V-shaped groove 205 contacts the outer middle side of the scraper disc 216. Two fixed plates 206 are fixedly connected to the inner wall of the drive box 201. A guide rod 207 is fixedly connected to the adjacent side of the two fixed plates 206. A slider 208 is slidably connected to the outer side of the guide rod 207. A threaded sleeve 209 is fixedly connected to the outer side of the slider 208. A lead screw 210 is rotatably connected to the adjacent side of the two fixed plates 206. The outer side of the lead screw 210 is rotatably connected to the inner side of the threaded sleeve 209. One end of the lead screw 210 passes through the outer wall of one of the fixed plates 206 and is fixedly connected to a handwheel 211. Rotating the handwheel 211 can drive the lead screw 210 to rotate, causing the threaded sleeve 209 to drive the driven wheel 212 to move, thereby adjusting the tightness of the hinge.

[0042] A driven wheel 212 is rotatably connected to the outer side of the threaded sleeve 209. An annular groove 213 is provided on the outer periphery of the driven wheel 212. A hinge consisting of multiple scraping discs 216 and connecting rings 217 is sleeved on the outside of the drive wheel 203 and the annular groove 213. The cleaning mechanism 3 includes two mounting shells 301 and a support base 302. The mounting shells 301 and the support base 302 are fixedly connected to the inner wall of the sewage tank 7 by different brackets. A rotating roller 303 is rotatably connected to the adjacent side of the mounting shells 301 and the support base 302. Multiple brushes 304 are fixedly connected to the outer side of the rotating roller 303. The multiple brushes 304 are in contact with multiple scraping discs 216 and multiple connecting rings 217 to clean the feces and dirt stuck to the outside of the hinge.

[0043] A dual-axis motor 310 is installed between the two mounting shells 301. After the dual-axis motor 310 is started, it drives the rotating roller 303 to rotate through the meshing bevel gear 311. The two output ends of the dual-axis motor 310, which pass through the inner wall of the two mounting shells 301 respectively, are fixedly connected to one end of the rotating roller 303 that passes through the inner wall of the mounting shell 301. The two bevel gears 311 located inside the same mounting shell 301 mesh. The top of the two mounting shells 301 and the support base 302 are fixedly connected to the support plate 305. The top of the two support plates 305 is fixedly connected to the spray plate 306. Multiple spray nozzles 307 are installed at the bottom of the spray plate 306. The spray nozzles 307 are located directly above the hinge composed of multiple scraping discs 216 and multiple connecting rings 217, and can spray and clean the brush 304 and the hinge from top to bottom. A water pipe 308 is fixedly connected to one end of the spray plate 306. Two cleaning units 3 installed in close proximity can share the same water pipe 308. A solenoid valve 309 is installed on the outside of the water pipe 308. After the solenoid valve 309 is opened, external water can be delivered to the spray plate 306 through the water pipe 308. One end of the water pipe 308 is connected to an external water source.

[0044] This invention also provides a manure removal method for a large-scale pig farm manure removal device, comprising the following steps:

[0045] Step 1: Pig manure leaks from the gaps in the grating above sewage area 1 into the V-shaped manure ditch 4 and slides into the guide pipe 218;

[0046] First, the sewage discharge area 1 is located below the pigsty. Pig manure will leak down from the gaps in the grating above sewage discharge area 1 and fall into the V-shaped manure ditch 4. It will slide down the slope of the V-shaped manure ditch 4. The surface of the V-shaped manure ditch 4 is a concrete structure. A construction concrete sealant is also used to make the slope smoother, which accelerates the falling speed of the manure and reduces the stickiness and adhesion of the manure on the slope. At this time, the manure will slide down to the guide pipe 218 in the middle or at the lowest point. The top of the guide pipe 218 at both positions is cut off by one-third to create a gap, and the manure will fall into the guide pipe 218 through this gap.

[0047] Step 2: Activate the scraping mechanism 2 so that the hinge scrapes the feces in the guide tube 218 into the sewage tank 7;

[0048] The servo motor 202 is started to drive the drive wheel 203 to rotate. The shift fork 204 will move the scraper disc 216. Turning the handwheel 211 will drive the lead screw 210 to rotate, thereby causing the threaded sleeve 209 to drive the driven wheel 212 to move. This can adjust the tightness of the hinge formed by the scraper disc 216 and the connecting ring 217. Then the hinge moves in the guide tube 218 to scrape the feces into the two sewage troughs 7. The hinges in the multiple scraper mechanisms 2 form a closed loop through the two lowest guide tubes 218 or through the two middle guide tubes 218 respectively.

[0049] Step 3: Activate the cleaning mechanism 3 to allow the brush 304 to clean the feces and dirt adhering to the outside of the hinge, and the nozzle 307 will spray water to rinse the brush 304 and the hinge. Then the sewage will be discharged from the drain outlet 8.

[0050] When the hinge is cleaning manure, the dual-axis motor 310 is started. Driven by the meshing bevel gear 311, the rotating roller 303 drives the brush 304 to rotate, cleaning the manure stuck to the outside of the hinge that passes between the two rotating rollers 303. Then, the solenoid valve 309 is opened, and water from one end of the water pipe 308 is transported to the spray plate 306. The spray nozzle 307 sprays water from top to bottom to clean the brush 304 and the hinge. The sewage falls into the sewage trough 7 and is discharged through the sewage outlet 8. Two cleaning mechanisms 3 installed close to each other will share the same water pipe 308, thus completing the manure cleaning process in a large-scale pig farm.

[0051] Specifically, the sewage discharge area 1 is located below the pigsty. The grating plate on top of it allows pig manure to fall naturally and accurately into the V-shaped manure ditch 4, preventing the accumulation of pig manure in the pigsty. The concrete surface of the V-shaped manure ditch 4 is exceptionally smooth after being treated with a sealing and curing agent. This not only accelerates the speed at which manure slides down the slope, but also significantly reduces the stickiness and adhesion of manure on the slope, allowing the manure to move more smoothly towards the guide pipe 218 in the middle or at the lowest point. The gaps formed by cutting off one-third of the top of the guide pipe 218 at the two locations provide a channel for manure to enter the guide pipe 218, ensuring that the manure can smoothly enter the subsequent treatment stage.

[0052] After the servo motor 202 is started, the drive wheel 203 rotates accordingly. The fork 204 on its outer periphery will orderly move the scraper disc 216, so that the hinge formed by the scraper disc 216 and the connecting ring 217 moves stably within the guide tube 218. During this process, turning the handwheel 211 can drive the lead screw 210 to rotate, which in turn causes the threaded sleeve 209 to drive the driven wheel 212 to move, thereby adjusting the tension of the hinge. This ensures that the hinge can both fit tightly against the inner wall of the guide tube 218 and move flexibly, efficiently scraping the feces and sludge into the two sewage troughs 7. The hinges in the multiple scraping mechanisms 2 pass through two lowest points of the guide tube 218. The design of forming a closed loop through the guide tube 218 or through two central guide tubes 218 can thoroughly clean the feces and dirt in different positions of the V-shaped manure ditch 4, avoiding cleaning dead corners. When the hinge is cleaning feces and dirt, its surface will inevitably stick to the feces and dirt. At this time, the dual-axis motor 310 is started. Under the transmission action of the meshing bevel gear 311, the rotating roller 303 will drive the brush 304 to rotate. The brush 304 can thoroughly clean the outside of the hinge that passes through the middle of the two rotating rollers 303, remove the sticky feces and dirt, keep the hinge clean, and prevent the feces and dirt from solidifying on the hinge and affecting subsequent use.

[0053] Then, the solenoid valve 309 is turned on, and the water source connected to the water pipe 308 is delivered to the spray plate 306. The spray nozzle 307 sprays water from top to bottom to clean the brush 304 and hinge. This not only washes away the manure and dirt swept off the brush 304, but also further cleans the hinge, ensuring that both are clean. The wastewater generated during cleaning falls into the drain trough 7 and is finally discharged through the drain outlet 8, preventing wastewater from accumulating in the device and causing pollution. At the same time, the two cleaning mechanisms 3 installed in close proximity share the same water pipe 308, which saves equipment costs and simplifies the pipeline layout, making the entire manure removal process more efficient and orderly. Through this series of continuous operations, timely and thorough cleaning of manure and wastewater in large-scale pig farms is achieved, creating a clean and hygienic environment for the pig farm.
