Description

Technical Field

[0001] This invention relates to the technical field of dry and wet separation and heat preservation for sow production rooms, specifically to a dry and wet separation and heat preservation for sow production rooms. Background Technology

[0002] During pregnancy and postpartum care, both sows and piglets have weak immune systems. If the ambient temperature is too low or too high, it can easily cause illness in sows or piglets, and in severe cases, it can lead to the death of piglets. Therefore, it is necessary to make adaptive adjustments to the growth environment to ensure that sows and piglets have suitable growth temperature and a hygienic environment during their growth.

[0003] Patent publication number CN206333166U relates to the technical field of dry and wet separation and heat preservation for sow farrowing rooms. It includes a concrete floor slab and a room structure on the concrete floor slab. A manure discharge device is embedded in the concrete floor slab, and a pigpen assembly is installed on the manure discharge device. The pigpen assembly includes a sow enclosure and a piglet box mounted on the manure discharge perforation plate. The sow enclosure and piglet box are arranged side-by-side, forming a partition channel in the middle, with end sealing plates at both ends of the partition channel. The side rail of the sow enclosure near the piglet box has a passageway for piglets. The side of the piglet box near the sow enclosure has a piglet entrance / exit. A ventilation opening is located on the top of the piglet box, and a heat lamp is installed inside the piglet box. A water curtain mechanism is installed on one wall of the room structure, and a circulating fan is embedded in the opposite wall. An air conditioning system is also installed inside the room. This patented sow farrowing and nursery room offers convenient temperature control, is clean and hygienic, and is suitable for the postpartum care of sows.

[0004] The sow farrowing and nursery room described in the above patent is easy to regulate in terms of temperature, clean and hygienic, and suitable for sows to nurse after farrowing. However, when the sow is moved to the left pen for warming during farrowing, she may be eating at the same time. Moving the sow while she is eating may cause her anxiety, tension, or even stress response, which may lead to difficulties during farrowing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dry and wet separation and heat preservation production room for sows, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a dry and wet separation and heat preservation production room for sows, including a pigpen, a feeding trough is fixedly installed at the front end of the pigpen, an iron door is rotatably installed on the side of the pigpen away from the feeding trough, a rotating plate is rotatably installed on the inner wall of the pigpen, an upper plate is fixedly installed on the inner wall of the pigpen, a lower plate is slidably installed on the inner wall of the upper plate, and a closing device is also provided on the inner wall of the pigpen;

[0007] The closing device includes a heater, a first rotating plate, a second rotating plate, a gear shaft, a gear rod, a first fixed rod, a push rod, an L-shaped rod, a first sliding block, a rotating rod, a controller, and a second fixed rod. The heater is fixedly installed on the top of the inner wall of the pigpen. The first rotating plate is rotatably installed on the side of the pigpen near the feeding trough, and the second rotating plate is rotatably installed on the side of the pigpen near the feeding trough. The gear shaft is fixedly installed on the movable end of the first rotating plate's rotating shaft. The gear rod is fixedly installed on the side of the second rotating plate near the first rotating plate. The first fixed rod is fixedly installed on the top of the first rotating plate. The push rods are respectively fixedly installed on the lower plate near the first and second rotating plates. The L-shaped rod is fixedly installed on the push rod near the first rotating plate. On one side, the first sliding block is slidably installed on the inner wall of the pigpen, the rotating rod is rotatably installed on the inner wall of the pigpen, the controller is fixedly installed on the inner wall of the pigpen, and the second fixed rod is fixedly installed on the end of the second rotating plate away from the feed trough. When the first sliding block slides, it will release the limit on the second fixed rod. When the limit on the second fixed rod is released, the push rod will push the second fixed rod to move. The movement of the second fixed rod will push the second rotating plate to rotate downwards, pushing the sow who is eating into the pigpen. This avoids the sow being pushed to the left side of the pigpen while she is eating. When the sow is pushed, her head may get stuck and cause injury. At the same time, it will cause the sow to feel uneasy and tense, and may even lead to a stress response, which may lead to difficulties during farrowing.

[0008] According to the above technical solution, the controller is electrically connected to the heater, the gear shaft and the gear rod mesh with each other, a spring is provided between the first sliding block and the pigpen, the spring is provided to drive the first sliding block back to its original position, a square groove is provided at the bottom of the first sliding block, the shape of the square groove matches the L-shaped rod, the side of the L-shaped rod near the square groove is set as an inclined surface, the inclined surface of the L-shaped rod is to push the first sliding block to move when the L-shaped rod contacts the square groove, and the rotating plate is a liquid-permeable plate.

[0009] According to the above technical solution, the inner wall of the pigpen is also equipped with a cleaning device for rinsing the inside of the pigpen and a collection device for collecting impurities from the rinsing. The cleaning device includes a water tank, a pressure plate, a hydraulic rod, a hydraulic cylinder, a round pipe, a nozzle, a rotating pressure rod, a storage frame, a long rod, a ratchet, a rack, a buffer plate, and a scraper. The water tank is fixedly installed on the top of the upper plate, the hydraulic cylinder is fixedly installed on the inner wall of the pigpen, the hydraulic rod is slidably installed on the inner wall of the hydraulic cylinder, the pressure plate is fixedly installed on the top of the hydraulic rod, the round pipe is fixedly installed on the side of the hydraulic cylinder away from the second rotating plate, the nozzle is fixedly installed on the end of the round pipe away from the hydraulic cylinder, the rotating pressure rod is rotatably installed on the inner wall of the pigpen, the ratchet is rotatably installed on the inner wall of the pigpen, and one end of the long rod... The ratchet is rotatably mounted at the end of the ratchet shaft away from the second rotating plate, and the other end of the long rod is rotatably mounted at the end of the rotating pressure rod shaft away from the second rotating plate. The rack is slidably mounted on the side of the lower plate near the second rotating plate. The storage frame is slidably mounted on the bottom of the inner wall of the pigpen. The buffer plate slides through the top of the rotating plate. The surface of the buffer plate has a sliding groove. The scraper is slidably mounted on the inner wall of the sliding groove. When the ratchet rotates, it pulls the soft rope to wind it up. When the soft rope is collected, it pulls the scraper to move and clean the excrement on the surface of the buffer plate, pushing the excrement into the storage frame for collection. Regularly cleaning the pigpen can effectively reduce the accumulation of pathogens and reduce the risk of disease transmission. A clean environment helps improve the health of piglets at birth and reduces the occurrence of diseases.

[0010] According to the above technical solution, the water tank and the hydraulic cylinder are connected by a hose. A second spring is provided between the hydraulic cylinder and the hydraulic rod. The second spring is provided to facilitate the hydraulic rod returning to its original position after the pressure is released. The round pipe connects the nozzle and the hydraulic cylinder. A pressure control valve is provided at the part of the round pipe connected to the hydraulic cylinder. The pressure control valve is provided to ensure that the liquid can only be sprayed from the nozzle when the hydraulic rod is squeezed. A one-way control valve is provided at the part of the hose connected to the hydraulic cylinder. The one-way control valve is provided to ensure that the liquid can only flow into the hydraulic cylinder in one direction.

[0011] According to the above technical solution, a No. 3 spring is provided between the buffer plate and the rotating plate. The No. 3 spring is provided to push the buffer plate back to its original position. A No. 4 spring is provided between the scraper and the buffer plate. The No. 4 spring is provided to drive the scraper back to its original position. A soft rope is provided between the ratchet and the scraper. The buffer plate is a liquid-permeable plate.

[0012] According to the above technical solution, the collection device includes a sliding plate, a rotating slide plate, a rotating rod, and a second sliding block. The sliding plate is slidably installed on the inner wall of the storage frame. One end of the rotating slide plate is slidably installed on the bottom of the inner wall of the storage frame, and the other end of the rotating slide plate is rotatably installed on the bottom of the sliding plate. The second sliding block is slidably installed on the bottom of the inner wall of the storage frame. One end of the rotating rod is rotatably installed on the side of the second sliding block near the sliding plate, and the other end of the rotating rod is rotatably installed on the side of the sliding plate near the second sliding block. When the sliding plate slides upward, it pulls the rotating slide plate to move, so the rotating slide plate will lean against the bottom of the inner wall of the storage frame. Sliding the sliding plate upward will enhance the collection of excrement and prevent excrement from falling outside the storage frame, increasing the difficulty of cleaning for staff and reducing work efficiency. At the same time, if excrement falls into some gaps that are difficult to clean completely, excrement residue will be generated. The residual excrement may cause the accumulation of pathogens, which will affect the subsequent birth of piglets.

[0013] According to the above technical solution, the collection device further includes a block, a plug, a baffle, and an inner plate. The block is fixedly installed at the bottom of the inner wall of the storage frame. A square groove is opened at the bottom of the buffer plate. The plug slides on the inner wall of the square groove. The baffle is fixedly installed at the bottom of the inner wall of the storage frame. The inner plate slides on the inner wall of the baffle. When the buffer plate returns to its original position, it will drive the plug upward. When the plug moves upward, it will lose contact with the limiting groove, and the storage frame can be removed to clean the inside of the storage frame. This avoids removing the storage frame while the sow is still on the surface of the buffer plate. If the sow is still on the surface of the buffer plate, she will produce excrement, and the liquid in the excrement will seep into the storage frame through the buffer plate and the rotating plate. If the storage frame is removed at this time, the liquid in the excrement will fall outside the storage frame, increasing the difficulty of cleaning for the staff and reducing work efficiency. By collecting and cleaning the excrement and treating it centrally, the excrement of the pig farm can be processed more efficiently for later use, such as organic fertilizer production or energy recovery.

[0014] According to the above technical solution, a No. 5 spring is provided between the plug-in and the square slot. The No. 5 spring is provided to drive the plug-in back to its original position. A limiting groove is opened on the top of the square block. The shape of the limiting groove matches the plug-in. A No. 6 spring is provided between the baffle and the inner plate. The No. 6 spring is provided to facilitate pushing the inner plate back to its original position. The top of the inner plate is provided with a slope. The slope on the top of the inner plate is provided to facilitate the inner plate sliding inward towards the baffle when it is contacted by external force when the storage frame is taken out, so as to avoid obstruction. The top of the plug-in is provided with a slope.

[0015] This invention provides a dry and wet separation and heat preservation system for sow farrowing rooms. It has the following beneficial effects:

[0016] (1) In this invention, the sliding block will release the limit on the second fixed rod when it slides. When the limit on the second fixed rod is released, the push rod will push the second fixed rod to move. The movement of the second fixed rod will push the second rotating plate to rotate downwards and push the sow who is eating into the pigpen. This avoids the sow being eating when she is pushed to the left side of the pigpen. When the sow is being pushed, her head may get stuck and cause injury. It will also cause the sow to feel uneasy and nervous, and may even lead to stress response, which may lead to difficulties during farrowing. The rotation of the gear shaft will drive the first rotating plate to rotate towards the feeding trough. The rotation of the first rotating plate will drive the first fixed rod to move. The movement of the first fixed rod will push the rotating rod to rotate. The rotation of the rotating rod will push the control end of the controller to rotate. The rotation of the control end of the controller will control the heater to start heating the left side of the pigpen. The heater heating the pigpen can keep the sow in a suitable physiological state and avoid stress response and health problems caused by low temperature.

[0017] (2) In this invention, when the lower plate moves downward, it will drive the rack to move. The movement of the rack will drive the ratchet to rotate. The rotation of the ratchet will pull the soft rope to wind up the soft rope. When the soft rope is collected, it will pull the scraper to move and clean the excrement on the surface of the buffer plate. Regular cleaning of the pigpen can effectively reduce the accumulation of pathogens and reduce the risk of disease transmission. A clean environment helps to improve the health level of piglets at birth and reduce the occurrence of diseases. The movement of the pressure plate will push the hydraulic rod to slide into the hydraulic cylinder. The sliding of the hydraulic rod into the hydraulic cylinder will push the liquid inside the hydraulic cylinder to enter the nozzle through the round pipe and spray it out to rinse the surface of the buffer plate and strengthen the cleaning of the buffer plate. It avoids that the excrement is attached too tightly, which makes it impossible for the scraper to clean the excrement smoothly. If the excrement is still attached to the surface of the buffer plate, the excrement remaining on the surface of the buffer plate may cause the accumulation of pathogens and affect the subsequent birth of piglets.

[0018] (3) In this invention, the upward sliding plate pulls the rotating slide plate, which then leans against the bottom of the inner wall of the storage box. The upward sliding plate enhances the collection of excrement, preventing it from falling outside the storage box, increasing the difficulty of cleaning for staff, and reducing work efficiency. Furthermore, if excrement falls into gaps that are difficult to clean completely, it will leave residue. This residue may lead to the accumulation of pathogens, affecting the subsequent birth of piglets. When the buffer plate returns to its original position, it will cause the insert to move upward. The upward movement of the insert will cause it to lose contact with the limiting groove. If contact occurs, the storage box can be removed for cleaning. This prevents the storage box from being removed while the sow is still on the buffer plate. If the sow is still on the buffer plate, she will excrete, and the liquid in the excrement will seep into the storage box through the buffer plate and rotating plate. If the storage box is removed at this time, the liquid in the excrement will fall outside the storage box, increasing the difficulty of cleaning for staff and reducing work efficiency. By collecting and cleaning the excrement and centrally processing it, the pig farm's excrement can be more efficiently processed for later use, such as organic fertilizer production or energy recovery.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-10 One embodiment of the present invention is: a dry and wet separation and heat preservation production room for sows, including a pigpen 1, a feeding trough 2 fixedly installed at the front end of the pigpen 1, an iron door 3 rotatably installed on the side of the pigpen 1 away from the feeding trough 2, a rotating plate 4 rotatably installed on the inner wall of the pigpen 1, an upper plate 5 fixedly installed on the inner wall of the pigpen 1, a lower plate 6 slidably installed on the inner wall of the upper plate 5, and a closing device is also provided on the inner wall of the pigpen 1;

[0032] The closing device includes a heater 7, a first rotating plate 8, a second rotating plate 9, a gear shaft 10, a gear rod 11, a first fixed rod 12, a push rod 13, an L-shaped rod 14, a first sliding block 15, a rotating rod 16, a controller 17, and a second fixed rod 18. The heater 7 is fixedly installed on the top of the inner wall of the pigpen 1. The first rotating plate 8 is rotatably installed on the side of the pigpen 1 near the feed trough 2. The second rotating plate 9 is rotatably installed on the side of the pigpen 1 near the feed trough 2. The gear shaft 10 is fixedly installed on the movable end of the rotating shaft of the first rotating plate 8. The gear rod 11 is fixedly installed on the side of the second rotating plate 9 near the first rotating plate 8. The first fixed rod 12 is fixedly installed on the top of the first rotating plate 8. The push rod 13 is fixedly installed on the lower plate 6 near the sides of the first rotating plate 8 and the second rotating plate 9, respectively. The L-shaped rod 14 is fixedly installed on the push rod 13 near the side of the first rotating plate 8 and the second rotating plate 9. On one side of the rotating plate 8, the first sliding block 15 is slidably installed on the inner wall of the pigpen 1, the rotating rod 16 is rotatably installed on the inner wall of the pigpen 1, the controller 17 is fixedly installed on the inner wall of the pigpen 1, and the second fixing rod 18 is fixedly installed on the end of the second rotating plate 9 away from the feed trough 2. When the first sliding block 15 slides, it will release the limit on the second fixing rod 18. When the limit on the second fixing rod 18 is released, the push rod 13 will push the second fixing rod 18 to move. The movement of the second fixing rod 18 will push the second rotating plate 9 to rotate downwards, pushing the sow who is eating into the pigpen 1. This avoids the sow being eating when she is pushed to the left side of the pigpen 1. When the sow is being pushed, her head may get stuck and cause injury. At the same time, it will cause the sow to feel uneasy and nervous, and may even lead to stress response, which may lead to difficulties during farrowing.

[0033] The controller 17 is electrically connected to the heater 7. The gear shaft 10 and the gear rod 11 mesh with each other. A spring is provided between the first sliding block 15 and the pigpen 1. The first spring is provided to drive the first sliding block 15 back to its original position. A square groove is provided at the bottom of the first sliding block 15. The shape of the square groove matches the L-shaped rod 14. The side of the L-shaped rod 14 near the square groove is set as an inclined surface. The inclined surface of the L-shaped rod 14 is provided to push the first sliding block 15 to move when the L-shaped rod 14 contacts the square groove. A gap is provided inside the rotating plate 4 so that liquid can pass through the rotating plate 4.

[0034] In this embodiment, the sows nearing their due date are first moved to the right side of pigpen 1 for temporary placement. The sows will eat from the food trough 2 to replenish their energy. When the sow is ready to give birth, the worker will control the lower plate 6 to slide inwards towards the upper plate 5. When the lower plate 6 is fully inserted into the upper plate 5, the worker will control the rotating plate 4 to rotate, pushing the sow to the left side of pigpen 1 to give birth. As the lower plate 6 slides inwards towards the upper plate 5, it will cause the push rod 13 to move upwards. The upward movement of the push rod 13 will push the L-shaped rod 14 upwards. When the L-shaped rod 14 moves upwards, its inclined surface will contact the square groove on the surface of the first sliding block 15. The inclined surface of the L-shaped rod 14 will then push the first sliding block 15 to slide, and the sliding of the first sliding block 15 will release... In addition to limiting the second fixing rod 18, when the limit of the second fixing rod 18 is released, the push rod 13 will push the second fixing rod 18 to move. The movement of the second fixing rod 18 will push the second rotating plate 9 to rotate downwards, pushing the sow who is feeding into the pigpen 1. The rotation of the second rotating plate 9 will drive the gear rod 11 to move. The movement of the gear rod 11 will drive the gear shaft 10 to rotate. The rotation of the gear shaft 10 will drive the first rotating plate 8 to rotate towards the feeding trough 2. The rotation of the first rotating plate 8 will drive the first fixing rod 12 to move. The movement of the first fixing rod 12 will drive the rotating rod 16 to rotate. The rotation of the rotating rod 16 will drive the control terminal of the controller 17 to rotate. The rotation of the control terminal of the controller 17 will control the heater 7 to start heating the left side of the pigpen 1.

[0035] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the inner wall of the pigpen 1 is further provided with a cleaning device for rinsing the inside of the pigpen 1 and a collection device for collecting impurities from rinsing the inside of the pigpen 1. The cleaning device includes a water tank 191, a pressure plate 192, a hydraulic rod 193, a hydraulic cylinder 194, a round pipe 195, a nozzle 196, a rotating pressure rod 197, a storage frame 198, a long rod 199, a ratchet 1991, a rack 1992, a buffer plate 1993, and a scraper 1994. The water tank 191 is fixedly installed on the top of the upper plate 5, the hydraulic cylinder 194 is fixedly installed on the inner wall of the pigpen 1, the hydraulic rod 193 is slidably installed on the inner wall of the hydraulic cylinder 194, the pressure plate 192 is fixedly installed on the top of the hydraulic rod 193, the round pipe 195 is fixedly installed on the side of the hydraulic cylinder 194 away from the second rotating plate 9, the nozzle 196 is fixedly installed on the end of the round pipe 195 away from the hydraulic cylinder 194, and the rotating pressure rod 197 is rotatably installed on the inner wall of the pigpen 1. A ratchet 1991 is rotatably mounted on the inner wall of the pigpen 1. One end of a long rod 199 is rotatably mounted on the end of the ratchet 1991 shaft away from the second rotating plate 9, and the other end of the long rod 199 is rotatably mounted on the end of the rotating pressure rod 197 shaft away from the second rotating plate 9. A rack 1992 is slidably mounted on the side of the lower plate 6 near the second rotating plate 9. A storage frame 198 is slidably mounted on the bottom of the inner wall of the pigpen 1. A buffer plate 1993 slides through the top of the rotating plate 4. A sliding groove is opened on the surface of the buffer plate 1993. A scraper 1994 is slidably mounted on the inner wall of the sliding groove. When the ratchet 1991 rotates, it pulls the soft rope to wind it up. When the soft rope is collected, it pulls the scraper 1994 to move and clean the excrement on the surface of the buffer plate 1993, pushing the excrement into the storage frame 198 for collection. Regularly cleaning the pigpen 1 can effectively reduce the accumulation of pathogens and reduce the risk of disease transmission. A clean environment helps to improve the health of piglets at birth and reduce the occurrence of diseases.

[0036] The water tank 191 is connected to the hydraulic cylinder 194 via a hose. A second spring is provided between the hydraulic cylinder 194 and the hydraulic rod 193. The second spring is provided to facilitate the hydraulic rod 193 returning to its original position after the pressure is released. The round pipe 195 connects the nozzle 196 and the hydraulic cylinder 194. A pressure control valve is provided at the part of the round pipe 195 that connects to the hydraulic cylinder 194. The pressure control valve is provided to ensure that liquid can only be sprayed from the nozzle 196 when the hydraulic rod 193 is squeezed. A one-way control valve is provided at the part of the hose that connects to the hydraulic cylinder 194. The one-way control valve is provided to ensure that liquid can only flow into the hydraulic cylinder 194 in one direction.

[0037] A third spring is provided between the buffer plate 1993 and the rotating plate 4. The third spring is provided to push the buffer plate 1993 back to its original position. A fourth spring is provided between the scraper 1994 and the buffer plate 1993. The fourth spring is provided to drive the scraper 1994 back to its original position. A soft rope is provided between the ratchet 1991 and the scraper 1994. The buffer plate 1993 also has a gap inside, so that liquid can also pass through the buffer plate 1993.

[0038] The collecting device includes a sliding plate 201, a rotating slide plate 202, a rotating rod 203, and a second sliding block 204. The sliding plate 201 is slidably mounted on the inner wall of the storage frame 198. One end of the rotating slide plate 202 is slidably mounted on the bottom of the inner wall of the storage frame 198, and the other end of the rotating slide plate 202 is rotatably mounted on the bottom of the sliding plate 201. The second sliding block 204 is slidably mounted on the bottom of the inner wall of the storage frame 198. One end of the rotating rod 203 is rotatably mounted on the side of the second sliding block 204 near the sliding plate 201, and the other end of the rotating rod 203 is rotatably mounted on the sliding plate 201. Near the second sliding block 204, the sliding plate 201 slides upward, which pulls the rotating slide plate 202 to move. The rotating slide plate 202 will lean against the bottom of the inner wall of the storage box 198. The upward sliding of the sliding plate 201 will enhance the collection of excrement and prevent excrement from falling outside the storage box 198, which would increase the difficulty of cleaning for staff and reduce work efficiency. At the same time, if excrement falls into some gaps that are difficult to clean completely, there will be excrement residue. The residue of excrement may cause the accumulation of pathogens, which will affect the subsequent birth of piglets.

[0039] The collecting device also includes a block 205, a plug 206, a baffle 207, and an inner plate 208. The block 205 is fixedly installed on the bottom of the inner wall of the storage frame 198. A square groove is formed at the bottom of the buffer plate 1993. The plug 206 slides on the inner wall of the square groove. The baffle 207 is fixedly installed on the bottom of the inner wall of the storage frame 198. The inner plate 208 slides on the inner wall of the baffle 207. When the buffer plate 1993 returns to its original position, it will cause the plug 206 to move upward. When the plug 206 moves upward, it will lose contact with the limiting groove, and the storage frame 198 can be removed to clean the inside of the storage frame 198. To prevent the storage box 198 from being removed while the sow is still on the surface of the buffer plate 1993, the sow will excrete while still on the surface of the buffer plate 1993. The liquid in the excrement will seep into the storage box 198 through the buffer plate 1993 and the rotating plate 4. If the storage box 198 is removed at this time, the liquid in the excrement will fall outside the storage box 198, increasing the difficulty of cleaning for the staff and reducing work efficiency. By collecting and cleaning the excrement and treating it centrally, the excrement of the pig farm can be processed more efficiently for later use, such as organic fertilizer production or energy recovery.

[0040] A No. 5 spring is provided between the plug-in 206 and the square slot. The No. 5 spring is provided to drive the plug-in 206 back to its original position. A limit groove is provided on the top of the block 205. The shape of the limit groove matches that of the plug-in 206. A No. 6 spring is provided between the baffle 207 and the inner plate 208. The No. 6 spring is provided to facilitate pushing the inner plate 208 back to its original position. The top of the inner plate 208 is provided with a slope. The slope on the top of the inner plate 208 is provided to facilitate sliding the inner plate 208 inward towards the baffle 207 when the storage box 198 is removed due to external force, so as to avoid obstruction. The top of the plug-in 206 is provided with a slope.

[0041] In this embodiment, when the sow is pushed to the left side of the pigpen 1, it will come into contact with the buffer plate 1993. The buffer plate 1993 will cushion the sow and prevent her from being injured when being pushed. After the sow is pushed to the left side of the pigpen 1 by the rotating plate 4, the lower plate 6 will move downwards back to its original position. When the lower plate 6 moves downwards, it will drive the rack 1992 to move. The movement of the rack 1992 will drive the ratchet 1991 to rotate. The rotation of the ratchet 1991 will pull the soft rope to wind it up. When the soft rope is collected, it will pull the scraper 1994 to move and clean the excrement on the surface of the buffer plate 1993, pushing the excrement into the storage box 198 for collection. When the ratchet 1991 rotates, it will drive the long rod 199 to move. The movement of the long rod 199 will drive the rotating pressure rod 197 to rotate. The rotation of the rotating pressure rod 197 will push the pressure plate 192 downwards. The movement of the pressure plate 192 will push the hydraulic rod 193 towards the hydraulic cylinder. The hydraulic rod 193 slides inside the cylinder 194, pushing the liquid inside the cylinder 194 through the round pipe 195 into the nozzle 196 for spraying, rinsing the surface of the buffer plate 1993 and strengthening the cleaning of the buffer plate 1993. When the rotating pressure rod 197 loses contact with the pressure plate 192, the hydraulic rod 193 will be pushed back to its original position by the second spring. When the hydraulic rod 193 returns to its original position, it will draw the liquid inside the water tank 191 into the hydraulic cylinder 194. When the sow has finished giving birth and the piglets can walk, the staff will drive the sow and piglets out of the pigpen 1. The staff will thoroughly clean and disinfect the pigpen 1 and turn off the heater 7. The staff will pull the rack 1992 to slide and lose contact with the ratchet 1991. The ratchet 1991 will then lose its pulling force on the scraper 1994, and the scraper 1994 will be pulled back to its original position by the fourth spring.

[0042] When scraper 1994 moves, it comes into contact with sliding block 204. Scraper 1994 then pushes sliding block 204 towards sliding plate 201. The movement of sliding block 204 pushes rotating rod 203, which in turn pushes sliding plate 201 upwards. This upward movement pulls rotating slide plate 202, causing it to lean against the bottom of the inner wall of storage box 198. The upward movement of sliding plate 201 enhances the collection of excrement, preventing it from falling outside storage box 198 and increasing the difficulty of cleaning for staff. To reduce work efficiency, when the sow moves to the left side of pigpen 1, the buffer plate 1993 on the right side will be pushed back to its original position by spring No. 3. When the buffer plate 1993 returns to its original position, it will drive the plug 206 to move upward. When the plug 206 moves upward, it will lose contact with the limit groove, and the storage box 198 can be removed to clean the inside of the storage box 198. When the storage box 198 is removed, the inclined edge of the inner plate 208 will contact the bottom of the buffer plate 1993, and the inner plate 208 will slide into the baffle 207 to avoid being blocked when the storage box 198 is removed, so that the storage box 198 can be removed normally.
