Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry equipment, and in particular to a novel environmental management system for slaughter pens. Background Art

[0002] With the rapid development of large-scale pig farming, efficient cleaning and sanitary management of pig houses for slaughter have become the core link to ensure the safety of pig farming. However, the existing technology still has the following systemic defects, which are in urgent need of breakthrough improvements. The mixing of feces and urine increases the difficulty of treatment. The conventional method adopts the design of a slope platform and a trough-type urine drainage groove. The urine drainage groove is easily clogged by fibers, and the urine drainage efficiency is less than 50%. The mixing of urine and feces greatly increases the COD concentration, and the odor in the pig house for slaughter is strong, which affects the regional environment and greatly increases the back-end sewage treatment load. There is also the problem that after the water in pig manure evaporates, a hardened layer is easily formed, and conventional scrapers cannot effectively remove it, resulting in a residual rate of hard feces exceeding 20%. When disinfecting the feces trough, the use of spraying and gravity separation methods will result in the disinfectant not being able to fully contact the bottom surface of the feces trough, resulting in uneven penetration of the disinfectant, incomplete disinfection, and difficult to eliminate harmful microorganisms. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a new type of slaughter pen environmental management system, which uses an inclined ramp instead of a urine drainage groove to make urine flow by itself, separate feces and urine in time, and can scrape out the feces groove more thoroughly, especially for hardened feces.

[0028] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0029] Depend on Figures 1 to 10 A new type of environmental management system for the slaughter pen is given, including a fresh air system 1, which is equipped with an air inlet arranged on the side wall of the pig house to be slaughtered and at least one air outlet arranged on the top; the fresh air system 1 realizes the air circulation and exchange between the pig house to be slaughtered and the outside of the pig house, and the cold air system 2 is equipped with an air inlet arranged on the side wall of the pig house to provide cold air for the pig house; the cold air system 2 cools the pig house, and when the temperature is high in summer, the pig house can be kept at a suitable temperature by blowing cold air into the pig house, and the excrement collection system is equipped with a support baffle 3, a manure ditch 5 arranged at the bottom of the support baffle 3, and a manure scraping device coordinated with the manure ditch 5, which is characterized in that

[0030] The slope of the inclined surfaces on both 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 collecting trough 9, and the lower side of the manure ditch 5 is provided with a liquid collecting trough 10;

[0031] The manure scraping device includes a support frame 6, a manure scraping plate 7, and a pull rod 8;

[0032] The manure scraper 7 is mounted on the support frame 6 and can be flipped 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 ditch 5;

[0033] The pull rod 8 can move relative to the support frame 6 along the direction of the manure ditch 5, and pull ropes are fixed at both ends of the pull rod 8. The movement of the pull rod 8 is achieved by driving the pull rope with the driving device. The pull rod 8 moves relative to the support frame 6 to drive the manure scraping plate 7 to flip over, and the support frame 6 moves toward the manure collecting trough 9. The manure scraping plate 7 flips over to contact with the manure ditch 5. Conversely, the manure scraping plate 7 flips over and does not contact with the manure ditch 5. After the pull rod 8 drives the manure scraping plate 7 to flip over, it can drive the support frame 6 to move.

[0034] 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 drives the scraper 7 to flip. That is, when the pull rod 8 drives the support frame 6 toward the manure collection trough 9, i.e., in the scraping direction, the scraper 7 is in contact with the bottom of the manure trough 5. Conversely, when the scraper 7 flips to a nearly horizontal position, the scraper 7 does not contact the bottom of the manure trough 5. After eliminating the relative length of the support frame, the pull rod 8 can move along the manure trough 5 with the support frame 6.

[0035] A deodorizing gas collecting pipe 11 is fixed to the side wall of the manure ditch 5. The deodorizing gas collecting pipe 11 is connected to a deodorizing system. When the deodorizing system is turned on, the deodorizing gas collecting pipe 11 generates negative pressure to collect the odor generated by the manure ditch 5 and then sends it to the deodorizing system for odor purification.

[0036] 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, wherein the fixing rod is used to support and fix the two side plates 12 and the middle plate 13 .

[0037] A rotating shaft 14 is fixed on the support frame 6, and a rotating part is fixed on the scraper 7. The rotating part is sleeved on the rotating shaft 14 and is rotatably connected to the rotating shaft 14. An intermediate guide part 15 is fixed on the intermediate plate 13, and the pull rod 8 is slidably connected to the intermediate guide part 15. At least one limiting groove 801 is provided on the pull rod 8, 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 7, and a driving part 17 is provided on the pull rod 8. The driving part 17 is provided with a driving groove, and the driving rod 16 extends into the driving groove. When the pull rod 8 moves toward the manure trough 5, the drive pin 38 first moves within the limit slot 801, that is, the pull rod 8 moves relative to the manure scraper 7. The drive member 17 drives the manure scraper 7 to rotate about the rotating shaft 14 through the drive rod 16. The limit rod 25 reaches the end of the limit slot 801, and the manure scraper 7 reaches the working position. Then, under the action of tension, the pull rod pulls the entire manure scraper device toward the manure collection trough. The driving device connected to the pull rope is a winch. Through the forward and reverse movement of the pull rope, the pull rod is driven to move toward the manure collection trough 9 and the liquid collection tank 10. The rotating shaft is fixedly connected to the two side plates and the middle plate.

[0038] A support rod 18 is provided on the back side of the manure scraper 7. The support rod 18 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 adjustment guide 19, and the adjustment guide 19 has an adjustment slot. The support rod 18 is fixed with an adjustment block 20. The adjustment block 20 extends into the adjustment slot and is slidably connected to the guide adjustment member. The adjustment guide 19 is fixed with a nut 21, and the nut 21 is screwed with a screw 22, which is rotatably connected to the adjustment block.

[0039] The scraper plate 7 is along the manure ditch 5, and the scraper plate 7 is an elastic steel plate. The range of the elastic steel plate at least includes the following part where the support rod 18 contacts the scraper plate 7. When the scraper plate 7 scrapes the pig manure, it will generate friction with the bottom of the manure ditch 5, so that the scraper plate 7 will produce a certain deformation. The deformation makes the scraper plate 7 have a better fit with the bottom of the manure ditch 5, so that the scraper plate 7 can better scrape the pig manure. The support rod 18 supports the scraper 7, reducing its deformation. The further the support rod 18 moves away from the scraper 7, the greater the deformation of the scraper 7, and the greater the contact force between the scraper 7 and the bottom of the dung ditch 5. By adjusting the position of the support rod 18, the deformation of the scraper 7 and the contact force between the scraper 7 and the bottom of the dung ditch 5 can be adjusted to prevent excessive or insufficient contact. When the bottom of the scraper 7 wears, the support rod 18 is adjusted backward, away from the scraper, so that the angle of inclination of the scraper 7 with the vertical plane decreases after deformation, increasing the contact force between the scraper 7 and the bottom of the dung ditch 5. This allows the scraper 7 to maintain good contact with the bottom of the dung ditch 5, improving the scraping effect and extending the service life of the scraper device. The guide member is moved by rotating the screw 22, which in turn drives the support rod 18 to move. The scraper inclination angle is adjusted by adjusting the position of the support rod 18. In order to ensure the stability of the support rod, a support rod slide groove is provided on the side panel. The end of the support rod extends into the support rod slide groove and is slidably connected to the support rod slide groove. The direction of the slide groove is consistent with the moving direction of the adjustment block driven by the screw.

[0040] The front side of the manure scraper 7 is symmetrically provided with a transverse rod 23 along the moving direction of the manure scraper device, and a plurality of cutting assemblies evenly distributed on the transverse rod 23. The cutting assemblies on different transverse rods 23 correspond to each other and are symmetrically arranged. The cutting plate 24 assembly includes a cutting plate 24. The transverse rod 23 drives the cutting plate 24 to make a reciprocating motion perpendicular to the moving direction of the manure scraper device. The transverse rod 23 is connected to a reciprocating drive mechanism that drives its reciprocating motion. Under the action of the transverse rod 23, the cutting plate 24 can drive the cutting plate 24 to move perpendicular to the manure ditch 5. It can first scrape the pig manure horizontally to break the adhesion between the pig manure and the bottom of the manure ditch 5, so that the manure scraper 7 can scrape it cleanly when it reaches this position.

[0041] The cross section of the cutting plate 24 is a V-shaped structure, 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.

[0042] A limiting rod 25 is provided below the transverse rod 23. A resilient telescopic rod 26 is fixed to the top of the cutting plate 24. A cutting connector is fixedly connected to the top of the resilient 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 cutting assembly and restricts its movement to a direction perpendicular to the manure ditch 5. The transverse rod 23 drives the cutting assembly to move via the cutting connector, which is slidably connected to the limiting rod 25. The cutting connector is lowered relative to the limiting rod 25 in a direction perpendicular to the manure ditch 5. The limiting rod 25 is perpendicular to the support rod 18.

[0043] The bottom edge of the cutting plate 24 is inclined at a certain angle, and the direction of inclination aligns with the bottom surface of the corresponding manure ditch 5. The plane of the bottom edge of the cutting plate 24 on the same transverse rod 23 is parallel to the bottom surface of the corresponding manure ditch 5. The cutting connector includes a connecting plate 27, with a middle member 28 fixed to its lower portion. The middle member 28 has different lengths for different cutting plates 24, and the lower portion of the middle member 28 is fixedly connected to the elastic telescopic rod 26. The different lengths of the middle 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 ditch 5. The elastic telescopic rod 26 includes an outer tube, an inner rod inserted into the outer tube, and a telescopic spring is installed between the bottom of the inner rod and the outer tube. When the cutting assembly moves, the inner rod's relative position to the bottom surface of the manure ditch 5 changes. The spring's telescopic assembly maintains contact between the cutting plate 24 and the bottom surface of the manure ditch 5, ensuring that the cutting plate 24 maintains a good manure scraping effect.

[0044] The upper portion of the pull rod 8 is provided with a cutting and lifting plate 29, and the cutting and lifting plate is provided with 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 toward the sump 10. Both ends of the limiting rod 25 are provided with a balancing plate 30, and the balancing plate 30 is provided with a balancing groove in the same inclination direction as the cutting groove 2901. The contact section of the limiting rod 25 with the balancing groove is a cylindrical surface. The balancing plate 30 is fixedly connected to the pull rod 8. The cutting and lifting plate 29 and the two balancing 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 position of the cutting assembly to change. 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 out of contact with the bottom surface of the scraper trough. When the manure scraping device moves toward the sump 10, the manure scraping plate 7 flips over to a nearly horizontal state, and the cutting plate 24 is out of contact with the bottom surface of the manure ditch 5, and no manure is scraped horizontally.

[0045] 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 manure ditch 5 adjacent to one side. The guide plate 33 is provided with a plurality of regularly undulating guide protrusions 35. The lower part of the vertical rod 33 contacts the guide protrusion 35. The vertical rod 34 is installed on the support frame 6 and is restricted to move up and down. The support frame 6 is provided with a compression spring 36 that presses the vertical rod 34 toward the guide plate 33. The upper end of the vertical rod 34 is rotatably connected to a rocker arm 37, and the free end of the rocker arm 37 is rotatably connected to the 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, the vertical rod 34 performs an up and down reciprocating motion with the cooperation of the compression spring 36. The up and down reciprocating motion of the vertical rod 34 drives the transverse rod 23 to reciprocate laterally through the rocker rod 37, and then drives the cutting plate 24 to reciprocate laterally, which can play the role of cutting and scraping feces, can cut and scrape hard feces, and then scrape the feces away under the action of the scraper plate, effectively improving the efficiency of scraping feces.

[0046] A spraying pipe 32 is installed on the support frame 6, and the spraying pipe 32 is arranged perpendicular to the direction of travel of the scraping device, and a plurality of nozzles facing the cutting plate 24 are installed on the spraying pipe 32. When the spraying pipe 32 is used to spray disinfectant, the scraping device moves toward the dung collecting trough 9.

[0047] When the feces are cleaned and the bottom of the feces ditch 5 needs to be disinfected, the spray pipe 32 is connected to the water pipe, which can be wound on the automatically recovering roller, and the water pipe is connected to a water pump and a disinfectant tank. When the feces scraping device moves toward the feces collecting trough 9, this is the disinfection spraying working state, and when it moves in the opposite direction, the disinfectant will not be sprayed. Each cutting plate 24 corresponds to a nozzle, and the nozzle is facing the bottom surface of the feces ditch 5 at the position of the cutting plate 24. In this way, after the disinfectant is sprayed onto the bottom surface of the feces ditch 5, the cutting plate 24 can block a portion of the disinfectant and gather it in the V-shaped groove formed by the cutting plate 24. As the cutting plate 24 moves, the disinfectant can be evenly distributed to the bottom surface of the feces ditch 5, so that the disinfectant can better contact the bottom surface of the feces ditch 5, thereby improving the disinfection effect.

[0050] b. Deodorization: Through feces and urine separation, the humidity of feces is effectively reduced, and the generation of odor is effectively suppressed. The odor generated in the feces ditch 5 is extracted through the deodorization collecting pipe 11, and then the deodorization system is used for purification to effectively remove the odor of the pig house to be slaughtered. The fresh air system 1 is used for ventilation to improve the air environment of the pig house to be slaughtered;

[0051] c. Cooling: The cold air system 2 provides cold air to the pig house to lower the temperature of the pig house and maintain a suitable temperature;
