Description

Technical Field

[0001] This invention relates to the field of livestock breeding equipment technology, and in particular to a novel environmental management system for slaughter pens. Background Technology

[0002] With the rapid development of large-scale pig farming, efficient cleaning and hygiene management of pigsties awaiting slaughter have become core aspects of ensuring livestock safety. However, existing technologies still suffer from the following systemic defects, requiring breakthrough improvements. The mixing of feces and urine exacerbates treatment difficulties. Conventional methods using sloping platforms and trough-type urine drainage channels are prone to clogging by fibrous materials, resulting in urine drainage efficiency of less than 50%. The mixing of urine and feces significantly increases COD concentration, produces a strong odor in the pigsty awaiting slaughter, impacting the surrounding environment and substantially increasing the load on downstream wastewater treatment. Furthermore, the evaporation of moisture from pig manure easily forms a hardened layer, which conventional scrapers cannot effectively remove, resulting in a hardened fecal residue rate exceeding 20%. When disinfecting manure troughs, spraying and gravity-flow methods often fail to ensure sufficient contact between the disinfectant and the bottom surface, leading to uneven disinfection and incomplete elimination of harmful microorganisms. Summary of the Invention

[0003] To address the above issues and overcome the shortcomings of existing technologies, the present invention aims to provide a novel environmental management system for slaughterhouses. This system utilizes inclined ramps instead of urine drainage channels, allowing urine to flow and separate naturally, effectively separating feces from urine. This also enables more thorough cleaning and scraping of the fecal channels, and is particularly effective for hardened feces. The solution is a new type of slaughterhouse environmental management system, including a fresh air system with at least one air inlet on the side wall of the slaughterhouse and at least one air outlet on the top; and a cold air system with an air inlet on the side wall of the slaughterhouse to provide cold air to the pigsty. The excrement collection system is equipped with a support baffle, a manure trough located at the bottom of the support baffle, and a manure scraping device that works in conjunction with the manure trough.

Both ends of the pull rod are fixed with pull ropes. The movement of the pull rod is achieved by a drive device that drives the pull ropes. The movement of the pull rod relative to the support frame causes the scraper plate to rotate. The support frame moves towards the manure collection trough, and the scraper plate rotates to contact the manure trough. Conversely, the scraper plate rotates back and forth without contacting the manure trough. After the pull rod drives the scraper plate to rotate, it can drive the support frame to move.

The support frame is fixed with an adjusting guide, which has an adjusting groove. An adjusting block is fixed to the support rod, and the adjusting block extends into the adjusting groove and is slidably connected to the adjusting guide.

The transverse bar drives the cutting plate to perform reciprocating motion perpendicular to the moving direction of the manure scraper device. The transverse bar is connected to a reciprocating drive mechanism that drives its reciprocating motion.

[0008] Preferably, the cutting plate has a V-shaped cross-section with the opening facing the side wall adjacent to the manure ditch, and the opening directions of the cutting plates on different transverse bars are opposite.

The cutting connector includes a connecting plate, and an intermediate piece is fixed to the lower part of the connecting plate.

The contact section between the limiting rod and the balance groove is a cylindrical surface. The balance plates are fixedly connected to the pull rod, and the cutting lifting plate and the two balance plates are fixedly connected by at least one reinforcing rod.

[0011] Preferably, the reciprocating drive mechanism includes a guide plate and a vertical rod. The guide plate is fixed on the side wall of the adjacent manure ditch. The guide plate is provided with a plurality of regularly undulating guide protrusions. The lower part of the vertical rod contacts the guide protrusions. The vertical rod is mounted on a support frame and restricted to moving up and down. The support frame is provided with a compression spring that presses the vertical rod against the guide plate.

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Depend on Figures 1 to 10 Providing a novel environmental management system for slaughterhouses, comprising: a fresh air system 1, equipped with at least one air inlet on the side wall of the slaughterhouse and at least one air outlet on the top; the fresh air system 1 enables air circulation and exchange between the slaughterhouse and the outside environment; a cooling air system 2, equipped with an air inlet on the side wall of the slaughterhouse to provide cool air; the cooling air system 2 cools the slaughterhouse, maintaining a suitable temperature in summer when temperatures are high by blowing cool air into the slaughterhouse; and an excrement collection system, equipped with a support baffle 3, a manure trough 5 at the bottom of the support baffle 3, and a manure scraper that cooperates with the manure trough 5. The system is characterized by... The slope of the two sides of the manure ditch 5 is 5 degrees, and the manure ditch 5 has an inclination of 3 degrees along the ditch direction. The higher side of the manure ditch 5 is provided with a manure collection trough 9, and the lower side of the manure ditch 5 is provided with a liquid collection trough 10. The manure scraping device includes a support frame 6, a scraper plate 7, and a pull rod 8; The scraper 7 is mounted on the support frame 6 and can rotate relative to the support frame 6; its lower end is configured to be V-shaped and fit with the inclined surfaces on both sides of the manure trough 5. The pull rod 8 can move relative to the support frame 6 along the direction of the manure ditch 5. Both ends of the pull rod 8 are fixed with pull ropes. The movement of the pull rod 8 is achieved by the drive device driving the pull ropes. The movement of the pull rod 8 relative to the support frame 6 causes the scraper plate 7 to flip. The support frame 6 moves towards the manure collection ditch 9, and the scraper plate 7 flips up to contact the manure ditch 5. Conversely, the scraper plate 7 flips up and does not contact the manure ditch 5. After the pull rod 8 drives the scraper plate 7 to flip, it can drive the support frame 6 to move.

[0025] The pull rod 8 can move a certain distance relative to the support frame 6. When the pull rod 8 moves relative to the support frame 6, it causes the scraper plate 7 to flip, and the pull rod 8 moves the support frame 6 towards the manure collection trough 9, so that the scraper plate 7 is in contact with the bottom of the manure trough 5. Conversely, if the scraper plate 7 flips to a near-horizontal position, it will not be in contact with the bottom of the manure trough 5. After the pull rod 8 contacts the support frame 6, it can move along the manure trough 5 along with the support frame 6.

[0026] A deodorizing gas collection pipe 11 is fixed on the side wall of the manure ditch 5, and the deodorizing gas collection pipe 11 is connected to a deodorizing system. After the deodorizing system is turned on, the deodorizing gas collection pipe 11 generates negative pressure to collect the odor generated in the manure ditch 5, and then sends it into the deodorizing system for odor purification.

[0027] The support frame 6 includes two symmetrically arranged side plates 12, a middle plate 13 located between the two side plates 12, and a fixing rod. The fixing rod is used to support and fix the two side plates 12 and the middle plate 13.

[0028] A rotating shaft 14 is fixed on the support frame 6, and a rotating component is fixed on the scraper plate 7. The rotating component is sleeved on the rotating shaft 14 and rotatably connected to the rotating shaft 14. An intermediate guide 15 is fixed on the intermediate plate 13, and a pull rod 8 is slidably connected to the intermediate guide 15. The pull rod 8 is provided with at least one limiting groove 801, and a driving pin 38 is provided in the limiting groove 801. The driving pin 38 is fixedly connected to the intermediate plate 13. A driving rod 16 is fixed on the upper part of the scraper plate 7. A driving component 17 is provided on the pull rod 8, and a driving groove is provided on the driving component 17. The driving rod 16 extends into the driving groove. When the pull rod 8 moves towards the manure trough 5, the drive pin 38 first moves within the limiting groove 801, meaning the pull rod 8 moves relative to the scraper plate 7. The drive component 17 drives the scraper plate 7 to rotate around the rotating shaft 14 via the drive rod 16. The limiting rod 25 reaches the end of the limiting groove 801, and the scraper plate 7 reaches the working position. Then, under the tension, the pull rod pulls the entire scraper device towards the manure collection trough. The drive device connected by the pull rope is a winch. Through the forward and reverse movement of the pull rope, the pull rod can be moved towards the manure collection trough 9 and the liquid collection trough 10. The rotating shaft is fixedly connected to the side plates and the middle plate.

[0029] The back side of the scraper 7 is provided with a support rod 18, which is used to limit the scraper to the working state of scraping manure. The support rod 18 is slidably connected to the support frame 6, and the sliding direction is along the working movement direction of the support frame 6. The support frame 6 is fixed with an adjusting guide 19, which is provided with an adjusting groove. The support rod 18 is fixed with an adjusting block 20, which extends into the adjusting groove and is slidably connected to the adjusting guide. A nut 21 is fixed on the adjusting guide 19, and a screw 22 is screwed onto the nut 21. The screw 22 is rotatably connected to the adjusting block.

[0030] The scraper 7 runs along the manure trough 5. The scraper 7 is made of elastic steel plate, and the range of the elastic steel plate includes at least the part below the support rod 18 that contacts the scraper 7. When the scraper 7 scrapes the pig manure, it will generate friction with the bottom of the manure trough 5. This causes the scraper 7 to deform to a certain extent. This deformation makes the scraper 7 have a better fit with the bottom of the manure trough 5, so that the scraper 7 can scrape the pig manure better. The support rod 18 supports the scraper plate 7, reducing its deformation. The further the support rod 18 moves away from the scraper plate 7, the greater the deformation of the scraper plate 7, and the greater the contact force with the bottom surface of the manure trough 5. By adjusting the position of the support rod 18, the deformation of the scraper plate 7 can be adjusted, thereby preventing the contact force between the scraper plate 7 and the bottom surface of the manure trough 5 from being too large or too small. After the bottom of the scraper plate 7 wears down, the support rod 18 is adjusted backward in the direction away from the scraper plate, so that the angle between the scraper plate 7 and the vertical plane after deformation is reduced, thus increasing the contact force between the scraper plate 7 and the bottom of the manure trough 5. This ensures that the scraper plate 7 maintains good contact with the bottom of the manure trough 5, improving the scraping effect and extending the service life of the scraping device. Rotating the screw 22 moves the guide component, which in turn moves the support rod 18. The tilt angle of the scraper can be adjusted by adjusting the position of the support rod 18. In order to ensure the stability of the support rod, a support rod groove is provided on the side plate. The end of the support rod extends into the support rod groove and slides in connection with the support rod groove. The direction of the groove is consistent with the direction of movement of the adjusting block driven by the screw.

[0031] The front side of the scraper plate 7 is symmetrically equipped with transverse rods 23 along the moving direction of the scraper device, and multiple cutting components are evenly distributed on the transverse rods 23. The cutting components on different transverse rods 23 correspond one-to-one and are symmetrically arranged. The cutting plate 24 assembly includes a cutting plate 24. The transverse rods 23 drive the cutting plate 24 to reciprocate perpendicular to the moving direction of the scraper device. The transverse rods 23 are connected to a reciprocating drive mechanism that drives its reciprocating motion. Under the action of the transverse rods 23, the cutting plate 24 can move perpendicular to the manure trough 5, which can first scrape the pig manure laterally, breaking the adhesion between the pig manure and the bottom of the manure trough 5, so that when the scraper plate 7 reaches this position, it can scrape it cleanly.

[0032] The cutting plate 24 has a V-shaped cross-section and the opening faces the side wall adjacent to the manure ditch 5. The opening directions of the cutting plates 24 on different transverse rods 23 are opposite.

[0033] A limiting rod 25 is provided below the transverse rod 23, and an elastic telescopic rod 26 is fixed to the upper part of the cutting plate 24. A cutting connector is fixedly connected to the upper part of the elastic telescopic rod 26. The cutting connector is fixedly connected to the transverse rod 23 and slidably connected to the limiting rod 25. The limiting rod 25 supports the installation of the cutting assembly and limits the movement of the support assembly to a direction perpendicular to the manure ditch 5. The transverse rod 23 drives the cutting assembly to move through the cutting connector. The cutting connector is slidably connected to the limiting rod 25, and the movement direction of the cutting connector relative to the limiting rod 25 is perpendicular to the manure ditch 5. The limiting rod 25 is perpendicular to the support rod 18.

[0034] The bottom edge of the cutting plate 24 is inclined at a certain angle, and the inclination direction is consistent with the inclination direction of the bottom surface of the corresponding manure trough 5. The plane where the bottom edge of the cutting plate 24 on the same horizontal rod 23 is located is parallel to the bottom surface of the corresponding manure trough 5. The cutting connector includes a connecting plate 27, and an intermediate member 28 is fixed to the lower part of the connecting plate 27. The length of the intermediate member 28 connected to different cutting plates 24 is different. The lower part of the intermediate member 28 is fixedly connected to the elastic telescopic rod 26. The different lengths of the intermediate member 28 ensure that the cutting plates 24 at different positions are at different heights, so that the overall inclination is consistent with the inclination of the bottom surface of the manure trough 5. The elastic telescopic rod 26 includes an outer cylinder, an inner rod inserted into the outer cylinder and slidably connected to the outer cylinder, and a telescopic spring between the bottom of the inner rod and the outer cylinder. In this way, after the cutting assembly moves, its position relative to the bottom surface of the manure trough 5 changes. Under the action of the spring telescopic assembly, the cutting plate 24 can always maintain contact with the bottom surface of the manure trough 5, so that the cutting plate 24 maintains a good manure scraping effect.

[0035] The upper part of the pull rod 8 is provided with a cutting lifting plate 29, which has an inclined groove. The limiting rod 25 passes through the cutting groove 2901, and the contact section with the cutting groove 2901 is a cylindrical surface. The cutting groove 2901 is inclined upward towards the liquid collection tank 10. Both ends of the limiting rod 25 are provided with balance plates 30, which have balance grooves in the same inclination direction as the cutting groove 2901. The contact section between the limiting rod 25 and the balance groove is a cylindrical surface. The balance plates 30 are fixedly connected to the pull rod 8. The cutting lifting plate 29 and the two balance plates 30 are fixedly connected by at least one reinforcing rod 31. The cutting plate 24 and the limiting rod 25 are in different positions. Under the action of the cutting groove 2901, the limiting rod 25 drives the cutting assembly to change position. When the scraper plate 7 is flipped to the non-working state, the limiting rod 25 drives the cutting assembly to move upward, so that the cutting plate 24 is disengaged from the bottom surface of the scraper trough. As the scraper moves toward the collection trough 10, the scraper plate 7 flips to a near-horizontal position, and the cutting plate 24 disengages from the bottom of the manure trough 5, thus not scraping the manure laterally.

[0036] The reciprocating drive mechanism includes a guide plate 33 and a vertical rod 34. The guide plate 33 is fixed on the side wall of the adjacent manure ditch 5. The guide plate 33 is provided with a plurality of regularly undulating guide protrusions 35. The lower part of the vertical rod 34 contacts the guide protrusions 35. The vertical rod 34 is mounted on a support frame 6 and is restricted to be able to move up and down. The support frame 6 is provided with a compression spring 36 that presses the vertical rod 34 against the guide plate 33. The upper end of the vertical rod 34 is rotatably connected to a swing rod 37. The free end of the swing rod 37 is rotatably connected to a transverse rod 23. As the vertical rod 34 moves along the direction of the guide plate 33, that is, along the direction of the groove, it reciprocates up and down with the cooperation of the compression spring 36. The reciprocating motion of the vertical rod 34 drives the horizontal rod 23 to reciprocate laterally through the swing rod 37, which in turn drives the cutting plate 24 to reciprocate laterally. This can cut and scrape the feces, breaking down hard feces, and then scraping them off under the action of the scraper, effectively improving the efficiency of scraping feces.

[0037] The support frame 6 is equipped with a spray pipe 32, which is arranged perpendicular to the direction of travel of the manure scraper. The spray pipe 32 is equipped with multiple nozzles facing the cutting plate 24. When the spray pipe 32 is used to spray disinfectant, the manure scraper moves towards the manure collection trough 9.

[0038] When the feces are cleaned and the bottom of the manure trough 5 needs to be disinfected, the spray pipe 32 is connected to a water pipe, which can be wound around an automatically retracting roller. The water pipe is connected to a water pump and a disinfectant tank. When the scraper moves towards the manure collection trough 9, this is the disinfection spraying operation mode; when it moves in the opposite direction, the disinfectant is not sprayed. Each cutting plate 24 corresponds to a nozzle, and the nozzle faces the bottom surface of the manure trough 5 at the position of the cutting plate 24. In this way, after the disinfectant is sprayed onto the bottom surface of the manure trough 5, the cutting plate 24 can block a portion of the disinfectant and collect it in the V-shaped groove formed by the cutting plate 24. As the cutting plate 24 moves, it can effectively distribute the disinfectant evenly to the bottom surface of the manure trough 5, allowing the disinfectant to better contact the bottom surface of the manure trough 5 and improving the disinfection effect.

[0039] Methods for environmental management of pig slaughter pens a. Separation of feces and urine: By setting a 3-degree inclination angle along the direction of the guide trough, urine can flow into the collection tank 10 below by gravity; the scraper device drives the feces upward into the collection tank 9; the scraper device repeats 5-6 times each time the feces are cleaned.

[0040] b. Deodorization: Through the separation of feces and urine, the humidity of feces is effectively reduced, and the generation of odor is effectively suppressed. The odor generated in the manure ditch 5 is extracted through the deodorization gas collection pipe 11, and then purified by the deodorization system to effectively remove the odor of the pigsty to be slaughtered. The fresh air system 1 is used for ventilation to improve the air environment of the pigsty to be slaughtered. c. Cooling: Cool air is provided to the pigsty through the cooling system 2 to lower the temperature of the pigsty and maintain a suitable temperature. d. Disinfection: While spraying disinfectant on the pigsty, the disinfectant in the disinfectant tank is sprayed out through the spray pipe 32 set on the manure scraper. With the scraping action of the cutting plate 24, the disinfectant is spread into the manure ditch 5 to disinfect the manure ditch 5.

[0041] The beneficial effects of this invention are as follows: The manure trough is set at a certain angle, allowing urine to separate from the feces through gravity flow, reducing fecal humidity and effectively improving the air environment in the pigsty awaiting slaughter; the cutting plate 24 effectively removes hard feces by scraping and cleaning the feces laterally, keeping the manure trough clean; the disinfection pipe in the scraping device, in conjunction with the scraping plate, ensures more even spraying and coating of disinfectant at the bottom of the manure trough 5, improving disinfection effect and the use of disinfectant; the cutting plate can fall downwards to contact the manure trough during scraping operations and move in the opposite direction, while the scraping plate is raised to disengage from the bottom of the manure trough, preventing feces from being scraped into the middle of the manure trough when the scraping device is not in operation, thus preventing interference with the natural flow of urine.
