[0026] The device can provide controllable enclosure space for a sow and multiple piglets. The sow moves in the area between the two limiting frames, and the piglets move in the space enclosed by the feeding trough 9, the front wall 6, the side wall 5, and the rear wall 7. The feeding trough 9 is used to provide feed for the sow. The automatic feeding mechanism can feed the feed into the feeding trough 9 in a timely and quantitative manner according to the setting, so that the sow can eat. When the sow lies down to nurse the piglets, the piglets can drink milk at the bottom of the limiting frame. When the sow lies down from a standing position, the piglets are pressed by the sow's body under the limiting frame. The piglets will cry in pain due to the pain, and the sound will be louder than ordinary sound. When the sound sensor 21 detects that the sound decibel reaches the preset value, it transmits the detection signal to the controller 20. The controller 20 starts all the hydraulic rods 18 according to the signal. The extension ends of the upper hydraulic rods 18 are shortened at the same time, driving the top of the limiting clamp to move to both sides. The extension ends of the lower hydraulic rods 18 are extended at the same time, driving the bottom of the limiting frame to move to the middle, thereby clamping the sow. Then the motor 15 is started at the same time. The motor 15 rotates to drive the lead screw 14 to rotate. The lead screw 14 rotates to drive the moving block 16 to move upward along the lead screw 14. The moving block 16 moves upward to drive the hydraulic rod 18 to move upward. The hydraulic rod 18 and the limiting frame are connected to each other, thereby driving the limiting frame to lift. The limiting frame clamps the sow, and the sow is lifted upward, thereby separating the sow's body from the piglets, timely rescuing the piglets from danger, and avoiding injury to the piglets.

[0027] Preferably, the limiting frame includes vertical rods 27, horizontal rods 19, middle limiting rods 28, top limiting rods 29, and curved rods 30. The vertical rods 27 are oppositely arranged.

The ends of the horizontal rods 19 at the bottom and the top are respectively rotationally connected to the extension ends of the hydraulic rods 18.

[0028] Because the sow is relatively large, in order to avoid the risk of injury to the piglets, the limiting frame is used to limit the movement range of the sow in the area between the two limiting frames. The horizontal rods 19 and the middle limiting rods 28 limit the movement space on both sides of the sow's body. The top limiting rods 29 limit the sow from jumping out from the top. Multiple curved rods 30 are arranged at intervals on the bottom horizontal rods 19, so that when the sow lies down to nurse the piglets, the piglets are separated, avoiding the piglets from fighting for the teats, ensuring that the piglets with physical deviations can also eat the sow's milk, and in addition, the curved rods 30 can clamp the sow and lift it upward under the drive of the hydraulic rods 18.

[0030] The automatic feeding mechanism can realize quantitative feeding. When the sow needs to eat, the controller 20 starts the solenoid valve 31, the solenoid valve 31 is opened, the feed particles in the hopper 10 fall into the discharge pipe 11 through the solenoid valve 31, as the feed continues to fall, the feed particles slowly accumulate, the height of the feed slowly rises, when the height of the feed reaches the height detected by the level sensor 33, the level sensor 33 transmits the inboard signal to the controller 20, the controller 20 closes the solenoid valve 31, then opens the solenoid valve 32, the feed in the discharge pipe 11 falls into the feeding trough 9 below, since the volume of the feed detected by the level sensor 33 in the discharge pipe 11 is constant, quantitative feeding can be realized through the controller 20 for several times, which is conducive to controlling and detecting the eating condition of the sow.

[0031] Preferably, it further comprises a small feeding trough 229, the small feeding trough 229 is arranged on the inner wall of the side plate 5, and a water pipe 23 is arranged above the small feeding trough 229.

[0032] The small feeding trough 229 is used for containing the feed and drinking water of piglets, and is arranged on the inner wall of the side plate 5, so that the small feeding trough 229 can be prevented from moving or being overturned.

[0035] Preferably, the bottom plate 1 is provided with a plurality of rectangular through holes 2.

[0036] The excrement, urine and food residues of the sow and piglets will fall through the through holes 2 to the bottom of the bottom plate 1, so that the top surface of the bottom plate 1 is kept clean, and the accumulation of excrement is avoided, which is not conducive to the health of the sow and piglets.
