Description

Feeding device for a sow nutrient regulation system Technical Field

[0001] This application relates to the field of pig farming equipment technology, and in particular to a feeding device for a sow nutrient regulation system. Background Technology

[0002] Sow nutritional supplements are nutritional products specifically designed for different physiological stages of sows. They are mainly used to adapt to the feed to meet the reproductive physiological needs of sows, thereby improving reproductive performance, ensuring milk production and piglet survival rate, protecting the sow's body condition, and extending her reproductive lifespan. The nutritional supplements mainly consist of staple feeds such as corn, wheat, and rice bran, combined with small or trace amounts of water-soluble vitamins, lactic acid bacteria liquid, chelated trace element liquid, etc., to meet the needs of sows at different stages of breeding.

[0003] Currently, sows are fed a measured amount of feed using a sow measuring cup to ensure their daily intake of nutrients. However, the existing sow measuring cup only measures the amount of solid pelleted feed, which falls into the pig trough. Water is added to the pig trough, which results in uneven mixing of the feed. This uneven mixing of dry and wet feed can easily lead to picky eating by pigs, and uneven moisture distribution can also affect digestion. Premixing the nutrients before adding them to the pig trough can cause residual feed to stick to the mixing drum and feeding pipe, which can easily breed bacteria and cause clumping and blockage of the pipes, and also waste the nutrients. Summary of the Invention

[0004] This application proposes a feeding device for a sow nutrient regulation system, which has the advantages of quantitative feeding, uniform mixing of nutrients, and easy cleaning of residues. It solves the problems of uneven drying and wetting of nutrients during quantitative feeding in existing sow feeding equipment, easy adhesion of residues in the mixing drum and feeding pipe, easy growth of bacteria, and clumping and blockage of pipes.

[0005] To achieve the above objectives, this application adopts the following technical solution: a feeding device for a sow nutrient regulation system, comprising: a fence and two crossbeams installed in a pigsty, wherein a pig feed trough and a water tank are provided at the bottom of the fence.

[0006] A feeding device is installed on the crossbeam. The feeding device includes a metering pipe to control the metered drop of solid pellet feed.

[0007] A mixing cylinder assembly is installed below the crossbeam. The mixing cylinder assembly includes a mixing cylinder connected to a metering feed pipe. The mixing cylinder is equipped with a spray mixing and sealing device inside. The spray mixing and sealing device includes a rotating rod. The bottom end of the rotating rod is provided with a sealing block for sealing the feed inlet of the mixing cylinder. The rotating rod is provided with a stirring blade and a horizontal pipe located above the stirring blade. When the stirring blade rotates with the rotating rod, it stirs the nutrients in the mixing cylinder, so that the solid pellet feed falling through the metering feed pipe and the liquid mixture sprayed by the horizontal pipe are mixed evenly. The horizontal pipe is provided with a nozzle.

[0008] The feed inlet at the bottom of the mixing drum is connected to a rotating pipe assembly installed on the fence. When delivering nutrients into the pig feed trough, the rotating pipe assembly is adjusted to be positioned above the pig feed trough by rotation. When delivering drinking water into the water tank, the rotating pipe assembly is adjusted to be positioned above the water tank by rotation.

[0009] Furthermore, the quantitative feeding pipe includes two positioning conveying pipes, with an adjusting rotating pipe movably fitted between them. A positioning connecting pipe is movably fitted on the outer side of the adjusting rotating pipe, and both the adjusting rotating pipe and the positioning connecting pipe are provided with matching feeding troughs. The bottom end of the positioning connecting pipe is fixedly connected to a first vertical pipe that connects to the feeding trough. The first vertical pipe is connected to the interior of the mixing cylinder. By controlling the rotation of the adjusting rotating pipe relative to the positioning connecting pipe until the two feeding troughs are connected, the solid pellet feed located in the adjusting rotating pipe falls into the first vertical pipe through the feeding trough. Then, by controlling the rotation of the adjusting rotating pipe relative to the positioning connecting pipe to misalign the two feeding troughs, the falling of the solid pellet feed can be stopped, thereby realizing the quantitative addition of feed. The adjusting rotating pipe and the positioning conveying pipe are equipped with a spiral auger, and the feed is conveyed by the rotation of the spiral auger. The feeding device also includes two positioning plates, which are fixed to two crossbeams by L-shaped mounting plates. The two positioning conveying pipes are fixedly installed on the two positioning plates to fix the quantitative feeding pipe.

[0010] Furthermore, a first gear is fixedly installed at one end of the adjusting tube. The first gear is movably mounted on the outside of the positioning feed tube. A quantitative control motor is fixedly installed on one of the positioning plates. A second gear that meshes with the first gear is fixedly installed on the output shaft of the quantitative control motor. The quantitative control motor drives the second gear to drive the first gear to rotate, thereby driving the adjusting tube to rotate relative to the positioning connecting tube, so as to control the position of the feeding chute on the adjusting tube and the positioning connecting tube, so as to control the feeding and stopping of feeding through the feeding chute.

[0011] Furthermore, a second vertical pipe is fixedly connected to one side of the top of the mixing cylinder. The second vertical pipe is movably sleeved with the first vertical pipe. Two linkage rods are also fixedly connected to the outer edge of the top of the mixing cylinder. Hanging plates are fixedly installed at the top of the two linkage rods, and bearing plates are fixedly installed at the top of the two crossbeams. The bottom of the hanging plate is movably connected to the top of the bearing plate, so that the mixing cylinder can be suspended below the two crossbeams. A weighing sensor is provided on the top of the bearing plate, which contacts the bottom of the hanging plate. When feed is continuously added into the mixing cylinder, the overall mass of the mixing cylinder increases. The amount of mass increase inside the mixing cylinder is monitored by the weighing sensor, which is the amount of feed added. When the preset value is reached, the linkage quantitative control motor starts to drive the second gear to drive the first gear and the adjusting tube to rotate, so that the feed chute on the adjusting tube and the positioning connecting tube is misaligned, and the addition of feed into the mixing cylinder is stopped, thereby realizing the control of feed metering.

[0012] Furthermore, a shaft connecting sleeve is fitted to the bottom of the rotating rod, and a sealing ring is provided on the top of the shaft connecting sleeve to prevent feed from entering through the connection between the rotating rod and the shaft connecting sleeve. The bottom of the shaft connecting sleeve is fixedly connected to the top of the sealing block. When the sealing block is used to seal the discharge port at the bottom of the mixing cylinder, the shaft connecting sleeve connects the sealing block and the rotating rod, allowing the rotating rod to rotate relative to the sealing block. This prevents the sealing block from rotating and easily causing wear when stirring the nutrients inside the mixing cylinder.

[0013] Furthermore, the stirring blades are provided in several groups, and the groups of stirring blades are arranged longitudinally at equal intervals on the rotating rod. There are two stirring blades in the same group, and the stirring blades arranged vertically are staggered. Several nozzles are fixedly provided at equal intervals at the bottom of the horizontal tube. The nozzles face the stirring blades below and are located at the center above the staggered stirring blades so that the water sprayed by the nozzles can act on the stirring blades below to clean the nutrient residue. There is also a nozzle at each end of the horizontal tube. The nozzles face the inner wall of the mixing cylinder so as to spray water on the inner wall of the mixing cylinder to clean the nutrient residue.

[0014] Furthermore, the mixing drum is equipped with a rotating water conveying device connected to the horizontal pipe. The rotating water conveying device includes a passive rotating pipe fixedly connected to the top of the horizontal pipe. The top end of the passive rotating pipe extends outside the top of the mixing drum and is fixedly connected to a rotary joint. A linkage plate is fixedly installed at the end of the rotary joint away from the passive rotating pipe. A cylinder located on one side of the passive rotating pipe is fixedly installed at the top of the enclosure. The piston shaft of the cylinder is fixedly connected to the end of the linkage plate away from the rotary joint. A water inlet pipe is connected to the end of the rotary joint away from the passive rotating pipe. One end of the water inlet pipe is movably fitted inside the linkage plate. The piston shaft driven by the cylinder drives the linkage plate, the rotary joint, and the passive rotating pipe to move up and down, thereby driving the horizontal pipe, rotating rod, shaft connecting sleeve, and sealing block inside the mixing drum to move up and down together, so as to open or close the discharge port at the bottom of the mixing drum cavity. Furthermore, through the connection of the rotary joint, when conveying liquid mixture or clean water into the mixing drum, it does not affect the overall rotation of the horizontal pipe and rotating rod driven by the rotary joint.

[0015] Furthermore, a stirring drive device for driving the passive rotating tube to rotate is fixedly installed on the top of the mixing cylinder. The stirring drive device includes a shaft rotating sleeve movably fitted on the top of the mixing cylinder, and the inner side of the shaft rotating sleeve is keyed to the outer side of the passive rotating tube, so that the shaft rotating sleeve can drive the passive rotating tube to rotate, and the passive rotating tube can move up and down relative to the shaft rotating sleeve. A limiting plate is movably fitted on the top of the shaft rotating sleeve, and the limiting plate is fixedly installed on the top of the mixing cylinder by a support rod. A third gear located between the limiting plate and the mixing cylinder is fixedly fitted on the outer side of the shaft rotating sleeve. A stirring drive motor is fixedly installed on the top of the limiting plate. A fourth gear meshing with the stirring drive motor is fixedly installed on the output shaft of the stirring drive motor. The stirring drive motor drives the fourth gear to drive the third gear to rotate, thereby driving the shaft rotating sleeve, the passive rotating tube, the horizontal tube, the rotating rod and the stirring blade to rotate, so that the stirring blade mixes the solid pellet feed and liquid mixture added to the mixing cylinder.

[0016] Furthermore, the rotating pipe assembly is fixedly installed on the outside of the fence via a pipe fixing plate, which is fixedly installed on the fence. The rotating pipe assembly includes two pipe fixing sleeves fixedly installed on the pipe fixing plate. An upper vertical pipe is rotatably sleeved between the two pipe fixing sleeves. A third vertical pipe is movably sleeved at the top of the upper vertical pipe. The top of the third vertical pipe is fixedly connected to the feed inlet at the bottom of the mixing cylinder. An S-shaped connecting pipe is fixedly connected to the bottom of the pipe fixing sleeve. A lower vertical pipe is fixedly connected to the end of the S-shaped connecting pipe away from the pipe fixing sleeve. By rotating the lower vertical pipe above the pig feed trough, the sow nutrient solution falls into the pig feed trough through the rotating pipe assembly. Then, by rotating the lower vertical pipe above the water tank, the water for the sow to drink falls into the water tank. A shaft linkage sleeve is fixedly sleeved on the lower vertical pipe. A pull rope connector is fixedly connected to the outside of the shaft linkage sleeve. Two pull ropes are fixedly connected to the pull rope connector. By winding and releasing the two pull ropes, the lower vertical pipe, the S-shaped connecting pipe, and the upper vertical pipe can be rotated.

[0017] Furthermore, the water tank is equipped with a partition. When the lower vertical pipe rotates to the top of the water tank, the partition is located outside the rotating pipe assembly. The partition divides the interior of the water tank into a drinking trough and a drain trough. An overflow trough is provided on the partition. When drinking water is added to the inside of the mixing drum to rinse the residual nutrient solution, the water carries the residual nutrient solution into the water tank for the sow to eat. When there is too much drinking water for rinsing, it overflows through the overflow trough. The bottom of the water tank is fixedly connected to a drain pipe that connects to the drain trough, and excess water is discharged through the drain pipe.

[0018] The beneficial effects of this invention are as follows: 1. The feeding device for a sow nutrient regulation system provided in this application, through the connection between the quantitative feed pipe and the mixing cylinder, allows solid pellet feed to be precisely and quantitatively added into the mixing cylinder, and mixed evenly with the liquid mixture in the mixing cylinder. This ensures precise and balanced nutrient intake for sows, which is beneficial to the healthy breeding of sows and avoids problems such as feeding stress and gastrointestinal discomfort in sows caused by uneven mixing of nutrients.

[0019] 2. By setting up spray nozzles inside the mixing drum, when providing liquid mixtures that are mixed with solid pellet feed, water can also be sprayed to wash away any residual nutrient solution inside the mixing drum, thus preventing the growth of bacteria and clumping of the residual nutrient solution.

[0020] 3. The design of connecting the mixing drum to the pig trough and water tank through the rotating tube assembly allows the nutrient solution mixed in the mixing drum to be introduced into the pig trough for the sows to eat. At the same time, the rotation of the rotating tube assembly allows drinking water to be used to rinse away any residual nutrients inside the mixing drum and then flow into the water tank for the sows to drink, thus avoiding the waste of residual nutrients.

[0023] 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.

[0024] As shown in Figures 1-3, a feeding device for a sow nutrient regulation system includes a fence 1 and two crossbeams 2. At least one feeding device 3 is fixedly installed on each of the two crossbeams 2 (only one is shown in the figures; if there are multiple feeding devices 3, they are distributed in an equidistant array on the crossbeams 2, which are then fixedly installed inside the pigsty). The feeding device 3 includes two positioning plates 301, which are respectively fixed to the two crossbeams 2 via L-shaped mounting plates. Positioning feeding pipes 302 are fixedly installed on each of the two positioning plates 301. An adjusting rotating pipe 303 is movably fitted between the positioning conveying pipes 302 and located between the two positioning plates 301. A positioning connecting pipe 304 is movably fitted on the outside of the adjusting rotating pipe 303. Both the adjusting rotating pipe 303 and the positioning connecting pipe 304 are provided with matching feeding troughs. The bottom end of the positioning connecting pipe 304 is fixedly connected to a first vertical pipe 305 that connects to the feeding trough. When the adjusting rotating pipe 303 rotates relative to the positioning connecting pipe 304 until the two feeding troughs are connected, the feed located in the adjusting rotating pipe 303 falls into the first vertical pipe 305 through the feeding trough.

[0025] The inner diameters of the adjusting pipe 303 and the positioning conveying pipe 302 are connected, and a spiral auger 306 is installed inside both the adjusting pipe 303 and the positioning conveying pipe 302. Feed is conveyed by the rotation of the spiral auger 306. (When several fences 1 are arranged crisscrossingly in the pigsty, the spiral auger 306 conveys feed to the fences 1 in that direction. The motor driving the spiral auger 306 and the feeding hopper can be located at one end of the positioning conveying pipe 302. This conveying method is existing known technology, so it will not be described in detail. The accompanying drawings in the instruction manual only show one fence 1 for easy labeling and do not show the motor driving the spiral auger 306.) A first gear 307 is fixedly installed at one end of the adjusting tube 303. The first gear 307 is movably fitted on the outside of the positioning feed tube 302. A quantitative control motor 308 is fixedly installed on one of the positioning plates 301. A second gear 309 that meshes with the first gear 307 is fixedly installed on the output shaft of the quantitative control motor 308. The quantitative control motor 308 drives the second gear 309 to drive the first gear 307 to rotate, which in turn drives the adjusting tube 303 to rotate relative to the positioning connecting tube 304, thereby controlling the position of the feeding chute on the adjusting tube 303 and the positioning connecting tube 304, so as to control the feeding and stopping of feeding through the feeding chute.

[0026] As shown in Figures 1-2 and 5-6, a mixing cylinder assembly 4 is fixedly installed below the feed chute on the lower part of the crossbeam 2, and the mixing cylinder assembly 4 is correspondingly located on the outside of the fence 1. The mixing cylinder assembly 4 includes a mixing cylinder 401, and a second vertical pipe 402 is fixedly connected to one side of the top of the mixing cylinder 401. The second vertical pipe 402 is movably connected to the first vertical pipe 305. The feed inside the positioning conveying pipe 302 and the adjusting rotating pipe 303 falls into the interior of the second vertical pipe 402 through the first vertical pipe 305. Two linkage rods 403 are also fixedly connected to the outer edge of the top of the mixing cylinder 401. A hanging plate 404 is fixedly installed at the top of the two linkage rods 403. A bearing plate 5 is fixedly installed at the top of the two crossbeams 2. The bottom of the hanging plate 404 is movably connected to the top of the bearing plate 5, so that the mixing cylinder 401 can... The feed cylinder 401 is suspended below the two crossbeams 2, and the top of the support plate 5 is equipped with a weighing sensor that contacts the bottom of the hanging plate 404 (the weighing sensor can be any existing known product and is not shown in the figure). When feed is continuously added into the mixing cylinder 401, the overall mass of the mixing cylinder 401 increases. The amount of mass increase inside the mixing cylinder 401 is monitored by the weighing sensor, which is the amount of feed added. When the preset value is reached, the linkage quantitative control motor 308 starts to drive the second gear 309 to drive the first gear 307 and the adjusting tube 303 to rotate, so that the feeding chute on the adjusting tube 303 and the positioning connecting tube 304 is misaligned, and the addition of feed into the mixing cylinder 401 is stopped, thereby realizing the control of feed metering (the weighing sensor and the quantitative control motor 308 are controlled by the software control system).

[0027] As shown in Figures 6 and 7, a spray mixing and sealing device 6 is rotatably installed inside the mixing drum 401. The spray mixing and sealing device 6 includes a rotating rod 601 located in the middle of the inner cavity of the mixing drum 401. A shaft connecting sleeve 602 is rotatably sleeved at the bottom end of the rotating rod 601, and a sealing ring is provided at the top of the shaft connecting sleeve 602 to prevent feed from entering through the connection between the rotating rod 601 and the shaft connecting sleeve 602. A sealing block 603 is fixedly connected to the bottom end of the shaft connecting sleeve 602. During the addition of feed into the mixing drum 401, the sealing block 603 blocks the discharge port at the bottom of the inner cavity of the mixing drum 401. Several sets of longitudinally equidistant mixing blades 604 are fixedly mounted on the rotating rod 601. Each set of mixing blades 604 consists of two blades, and the two mixing blades 604 in the same set are symmetrically distributed. A horizontal pipe 605 is fixedly connected to the top of the rotating rod 601. The two ends of the horizontal pipe 605 are respectively facing one end of the two mixing blades 604 in the same set. Each end of the mixing drum 401 is equipped with a nozzle 606, the nozzle holes of which face the inner wall of the mixing drum 401. Several nozzles 606 are also fixedly installed at the bottom of the horizontal pipe 605, arranged at equal intervals, with the nozzle holes of the nozzles 606 facing the stirring blades 604 below. The stirring blades 604 are arranged alternately. While adding solid pellet feed (corn, wheat, bran, soybean meal, etc.) to the mixing drum 401 in a measured amount, liquid mixture (water and water-soluble vitamins, lactic acid bacteria liquid, chelated trace element liquid, etc.) is also sprayed in a measured amount through the nozzles 606. In conjunction with the rotating rod 601 driving the stirring blades 604 to rotate, the nutrient solution for sows added to the mixing drum 401 is mixed evenly, which helps to ensure that the sows' nutrient intake is accurate and balanced. After the mixed nutrient solution is added to the mixing drum 401, clean water is conveyed and sprayed out by the nozzles 606 to rinse the inside of the mixing drum 401, reducing the residual amount of nutrient solution after mixing inside the mixing drum 401.

[0028] As shown in Figures 6-8, a rotating water conveying device 7 connected to a horizontal pipe 605 is provided inside the mixing drum 401. The rotating water conveying device 7 includes a passive rotating pipe 701 fixedly connected to the top of the horizontal pipe 605. The top end of the passive rotating pipe 701 extends outside the top of the mixing drum 401 and is fixedly connected to a rotary joint 702. A linkage plate 703 is fixedly installed at the end of the rotary joint 702 away from the passive rotating pipe 701. A cylinder 704 located on one side of the passive rotating pipe 701 is fixedly installed at the top of the enclosure 1. The piston shaft of the cylinder 704 is fixedly connected to the end of the linkage plate 703 away from the rotary joint 702. A water inlet pipe 705 is connected, with one end of the water inlet pipe 705 movably fitted inside the linkage plate 703. The piston shaft driven by the cylinder 704 moves the linkage plate 703, the rotary joint 702, and the passive rotating pipe 701 up and down, thereby driving the horizontal pipe 605, the rotating rod 601, the shaft connecting sleeve 602, and the sealing block 603 inside the mixing drum 401 to move up and down together, so as to open or close the discharge port at the bottom of the inner cavity of the mixing drum 401. Furthermore, through the connection of the rotary joint 702, when liquid mixture or clean water is conveyed into the mixing drum 401, it does not affect the overall rotation of the horizontal pipe 605 and the rotating rod 601 driven by the rotary joint 702.

[0029] As shown in Figures 6-9, a stirring drive device 8 for driving the passive rotating tube 701 to rotate is fixedly installed on the top of the mixing cylinder 401. The stirring drive device 8 includes a shaft rotating sleeve 801 movably fitted on the top of the mixing cylinder 401, and the inner side of the shaft rotating sleeve 801 is connected to the outer side of the passive rotating tube 701 via a sliding key, so that the shaft rotating sleeve 801 can drive the passive rotating tube 701 to rotate. At the same time, the passive rotating tube 701 can move up and down relative to the shaft rotating sleeve 801. A limiting plate 802 is movably fitted on the top of the shaft rotating sleeve 801. The limiting plate 802 is fixedly installed on the top of the mixing cylinder 401 by a support rod 803. A third gear 804 is fixedly mounted on the side between the limiting plate 802 and the mixing cylinder 401. A stirring drive motor 805 is fixedly mounted on the top of the limiting plate 802. A fourth gear 806 meshing with the stirring drive motor 805 is fixedly mounted on the output shaft of the stirring drive motor 805. The stirring drive motor 805 drives the fourth gear 806 to drive the third gear 804 to rotate, which in turn drives the shaft rotating sleeve 801, the passive rotating tube 701, the horizontal tube 605, the rotating rod 601 and the stirring blade 604 to rotate, so that the stirring blade 604 mixes the solid pellet feed and liquid mixture added to the mixing cylinder 401.

[0030] As shown in Figures 1, 5-6, and 10-12, a rotating pipe assembly 9 is connected to the feed inlet at the bottom of the mixing cylinder 401. The rotating pipe assembly 9 is fixedly installed on the outside of the enclosure 1 (the inside of the enclosure 1 is the sow's activity area) via a pipe fixing plate 10. The pipe fixing plate 10 is fixedly installed on the enclosure 1. The rotating pipe assembly 9 includes two pipe fixing sleeves 901 fixedly installed on the pipe fixing plate 10. An upper vertical pipe 902 is rotatably sleeved between the two pipe fixing sleeves 901. A third vertical pipe 903 is movably sleeved at the top of the upper vertical pipe 902. The top of the third vertical pipe 903 is fixedly connected to the feed inlet at the bottom of the mixing cylinder 401. The pipe fixing sleeves 901... An S-shaped connecting pipe 904 is fixedly connected to the bottom end. The end of the S-shaped connecting pipe 904 away from the pipe fixing sleeve 901 is fixedly connected to a lower vertical pipe 905. The bottom of the enclosure 1 is provided with a pig feed trough 11 and a water tank 12 located below the lower vertical pipe 905. The bottom of the inner cavity of the pig feed trough 11 is designed with a slope to facilitate the nutrient solution to slide into the inner side of the enclosure 1 for the sow to eat. By rotating the lower vertical pipe 905 to the top of the pig feed trough 11, the sow's nutrient solution falls into the inside of the pig feed trough 11 through the rotating pipe assembly 9. Then, by rotating the lower vertical pipe 905 to the top of the water tank 12 (i.e., the state shown in Figure 13), the water for the sow to drink falls into the inside of the water tank 12.

[0031] A shaft linkage sleeve 906 is fixedly fitted onto the lower vertical pipe 905. A pull rope connector 907 is fixedly connected to the outside of the shaft linkage sleeve 906. Two pull ropes (not shown in the figure) are fixedly connected to the pull rope connector 907. One end of each pull rope runs along both ends of the crossbeam 2. When one of the pull ropes is pulled, the lower vertical pipe 905, the S-shaped connecting pipe 904, and the upper vertical pipe 902 rotate relative to the third vertical pipe 903 until the bottom end of the lower vertical pipe 905 is directly above the pig feed trough 11. At this time, the nutrient solution in the mixing cylinder 401 is transported into the pig feed trough 11 through the rotating pipe assembly 9 for the sow. When feeding the pigs, pulling another rope causes the lower vertical pipe 905, S-shaped connecting pipe 904, and upper vertical pipe 902 to rotate relative to the third vertical pipe 903 until the bottom of the lower vertical pipe 905 is directly above the pig feed trough 11. This allows the drinking water, which has been used to clean the inside of the mixing cylinder 401, to carry the residual nutrients into the water tank 12 for the sows to eat, thus avoiding waste caused by nutrient residue. The rope can be used to link the rotating pipe assemblies 9 on multiple fences 1, thereby controlling the rotation of the lower vertical pipes 905 on the same row of fences 1. The winding and unwinding of the rope can be driven by a winding machine.

[0032] The water tank 12 is equipped with a partition 13. When the lower vertical pipe 905 rotates to the top of the water tank 12, the partition 13 is located outside the rotating pipe assembly 9, so that the partition 13 divides the interior of the water tank 12 into a drinking trough and a drain trough. An overflow trough 131 is provided on the partition 13. When drinking water is added to the inside of the mixing cylinder 401 to rinse the nutrient residue, the water carries the nutrient residue into the water tank 12 for the sow to eat. When there is too much drinking water for rinsing, it overflows through the overflow trough 131. The bottom of the water tank 12 is fixedly connected to a drain pipe 14 that connects to the drain trough. Excess water is discharged through the drain pipe 14.
