Description

Technical Field

[0001] The invention belongs to the technical field of pig farm breeding equipment, and in particular relates to a sow farrowing pen which is convenient for feeding piglets with breast milk. Background Art

[0002] The sow farrowing pen (also known as the sow farrowing bed) is a device used for sow farrowing and feeding piglets. It is mainly composed of a sow positioning frame, piglet fence, piglet incubator, manure-leaked floor, sow trough and piglet trough. There are levers on both sides of the sow positioning frame to prevent piglets from being crushed to death or injured by the sow while lying down.

[0003] The existing document CN206596500U discloses a typical lactating sow delivery bed, including: a delivery bed floor (i.e., a manure-slatted board), having a piglet activity area and a sow activity area, the piglet activity areas are successively provided with piglet barriers, isolation fences are provided on the left and right sides of the sow activity area, for separating the piglet activity area from the sow activity area, a top fence is provided above the isolation fence, a rear fence door is located at the rear of the sow activity area and is provided between the isolation fences, a dividing rod (also called an anti-food snatching fence foot) is provided at the lower part of the isolation fence, and a front fence door is located at the front of the sow activity area and is provided between the isolation fences.

[0004] As mentioned above, there are still some problems in the actual production application of sow farrowing crates, including: in the later period of piglet rearing (the period from fifteen days after the piglets are born to before they are slaughtered), it is not convenient for the piglets to eat breast milk smoothly, and it is not convenient for the sows to lie down in a directional and comfortable manner. Summary of the invention

[0005] At least in view of the problems mentioned in the background technology, the present invention aims to provide a sow farrowing pen that is convenient for feeding piglets with breast milk.

[0006] The present invention adopts the following technical solution.

[0007] A sow farrowing pen for breastfeeding piglets comprises a sow living area and piglet living areas located on both sides of the sow living area, a manure-leaking plate with slit holes is provided on the bottom sides of the sow living area and the piglet living area, an incubator is provided in the middle of the manure-leaking plate, vertical railings fixedly installed on the top sides of the manure-leaking plate are provided on both sides of the sow living area, a feeding trough is provided in the sow living area, a fixed guardrail is fixedly installed on the vertical railing on one side close to the incubator, a movable guardrail is connected to the vertical railing on the other side, a transmission component for driving the movable guardrail to rotate or lift is provided on the bottom side of the manure-leaking plate, and a trigger switch for controlling the operation of the transmission component is provided on the manure-leaking plate and located in the sow living area.

[0008] In order to enable the sows to lie more comfortably and to facilitate the sows to lie in a certain direction, the fixed guardrails are set vertically and the movable guardrails are set at an angle, so that the cross-section of the sow's living area can be a right-angled trapezoid. As a preferred solution, the movable guardrail includes a movable frame rotatably connected to the vertical railing, and a plurality of bent partition rods are fixedly installed on the bottom side of the movable frame.

[0009] In order to improve the comfort of piglets during feeding, the outer wall of the dividing rod is provided with a silicone sheath.

[0010] As one of the preferred solutions of the present invention, the transmission assembly includes a mounting seat fixedly mounted on the bottom side of the manure-slatted plate, a stepper motor is fixedly mounted inside the mounting seat, a winding roller and a guide wheel are fixedly mounted on the bottom side of the manure-slatted plate corresponding to the front side of the stepper motor, and a pulley inside the winding roller is fixedly connected to one end of the output shaft of the stepper motor, a steel cable is wound inside the winding roller, a rotating shaft is fixedly mounted on both ends of the movable frame, a winding roller is fixedly mounted on the outside of the rotating shaft, and the other end of the steel cable is wound around the outside of the winding roller. More preferably, the stepper motor is connected to the trigger switch signal.

[0011] Furthermore, the winding roller is rotatably connected to the interior of the vertical railing, and the steel cable passes through the hollow cavity of the vertical railing.

[0012] As the second preferred scheme of the present invention, vertically arranged strip holes are provided on the vertical railing, and the movable guardrail includes a movable frame movably connected to the vertical railing, and a plurality of bent partition rods are fixedly installed on the bottom side of the movable frame, and the rectangular cross bar of the movable frame is gap-fitted in the strip hole; the transmission assembly includes multiple fixed pulleys and at least two trigger switches arranged at intervals, the head end of the steel cable is connected to the trigger switch, the steel cable passes around the fixed pulley and its tail end is connected to the rectangular cross bar, when all the trigger switches are pressed down at the same time, the rectangular cross bar is pulled up by the steel cable, thereby realizing the upward movement of the movable frame, at this time, the height between the lower end of the movable frame and the surface of the manure-slatted board is greater than the height of the piglet, and after the pressure applied to all the trigger switches is cancelled, the movable frame is reset under the action of gravity.

[0013] Furthermore, all trigger switches are installed below the slope of the movable guardrail. With this solution, a simple and ingenious solution is used to achieve that the trigger switch can be pressed down only when the sow is lying down (the sow cannot press down the trigger switch when standing, and the piglets cannot press down the trigger switch because their weight is not large enough), which effectively solves the problem of accidentally touching the trigger switch.

[0014] Furthermore, the top surface of the trigger switch is a slope, which faces the inside of the sow living area (opposite to the slope of the movable frame). Adopting such a solution can improve the comfort of the pigs when pressing the trigger switch and prevent the pigs from being injured by the edges of the trigger switch.

[0015] Beneficial effects: The scheme of the present invention can facilitate piglets to smoothly eat breast milk throughout the whole period of piglet breeding, and at the same time facilitate sows to flex and stretch their legs, and facilitate sows to lie in a directional and comfortable manner.

[0018] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0019] Combination Figures 1 to 4 As shown, a sow farrowing pen for breastfeeding piglets comprises a sow living area and piglet living areas located on both sides of the sow living area, a manure-leaking plate 1 with slit holes is provided on the bottom sides of the sow living area and the piglet living area, an incubator 2 is provided in the middle of the manure-leaking plate 1, vertical railings 3 fixedly installed on the top side of the manure-leaking plate 1 are provided on both sides of the sow living area, a feeding trough 4 is provided in the sow living area, a fixed guardrail is fixedly installed on the vertical railing 3 on one side close to the incubator 2, and a movable guardrail is connected to the vertical railing 3 on the other side, a transmission assembly 5 for driving the movable guardrail to rotate is provided on the bottom side of the manure-leaking plate 1, and a trigger switch 6 for controlling the operation of the transmission assembly 5 is provided on the manure-leaking plate 1 located in the sow living area, the trigger switch 6 is installed below the inclined plane to which the movable guardrail belongs, and the trigger switch 6 can be pressed down only when the sow lies down. Among them, the fixed guardrail is arranged vertically and the movable guardrail is arranged obliquely, so that the cross section of the sow living area (the cross section in the length direction of the sow living area) can be a right-angle trapezoid.

[0020] In this embodiment, the movable guardrail includes a movable frame 7 (rotatably connected to the vertical railing 3) Figure 1A movable frame 7 is arranged on the vertical railing 3 on the side away from the incubator 2), the movable frame 7 is arranged obliquely (corresponding to the hypotenuse of the right-angled trapezoid), and a plurality of bent partition rods 8 are fixedly installed on the bottom side of the movable frame 7, and the outer wall of the partition rod 8 is provided with a silicone sheath 9. Since sows have an instinct to always tend to perform comfortable movements, in this solution, when the sow's back is against the movable frame 7, the sow's body will have a sense of danger and awkwardness of hanging and falling (the movable frame 7 is arranged obliquely), and the sow can lie comfortably only when the sow's back is against the fixed guardrail (corresponding to the vertical side of the right-angled trapezoid), thereby effectively guiding the sow to lie in a directional manner.

[0021] In this embodiment, the transmission assembly 5 includes a mounting seat 10 fixedly mounted on the bottom side of the slatted floor 1, a stepper motor 11 is fixedly mounted inside the mounting seat 10, a winding roller 12 and a guide wheel 13 are fixedly mounted on the bottom side of the slatted floor 1 corresponding to the front side of the stepper motor 11, and the pulley inside the winding roller 12 is fixedly connected to one end of the output shaft of the stepper motor 11, and a steel cable 14 is wound inside the winding roller 12, a rotating shaft 15 is fixedly mounted on both ends of the movable frame 7, a winding roller 16 is fixedly mounted on the outside of the rotating shaft 15, and the other end of the steel cable 14 is wound around the outside of the winding roller 16. The stepper motor 11 is connected to the trigger switch 6 by signal. The winding roller 16 is rotatably connected inside the vertical railing 3, and the steel cable 14 runs through the hollow cavity of the vertical railing 3.

[0022] When in use, when the sow lies down (the sow's head faces the feeding trough 4, and the sow's back faces the fixed guardrail next to the incubator 2), she will press down the trigger switch 6, which will then trigger the stepper motor 11 to work and drive the winding roller 12 to rotate, reeling the steel cable 14, and at the same time drive the winding roller 16 outside the rotating shaft 15 to rotate, and then drive the movable frame 7 to flip through the rotating shaft 15, so as to lift / elevate the lower part of the movable frame 7, so as to facilitate the piglets to feed breast milk; and after the piglets finish feeding breast milk, the sow gets up, and at this time the sow no longer presses down the trigger switch 6, and the stepper motor 11 stops working. At this time, under the action of the movable frame 7's own gravity, the movable railing will deflect downward and reset. Example 2

[0023] Combination Figure 1 , Figures 5 to 7As shown, a sow farrowing pen for breastfeeding piglets comprises a sow living area and piglet living areas located on both sides of the sow living area, a manure-leaking plate 1 with slit holes is provided on the bottom sides of the sow living area and the piglet living area, an incubator 2 is provided in the middle of the manure-leaking plate 1, vertical railings 3 are fixedly installed on the top side of the manure-leaking plate 1 on both sides of the sow living area, and a feeding trough 4 is provided in the sow living area, characterized in that: a fixed guardrail is fixedly installed on the vertical railing 3 on one side close to the incubator 2, and a movable guardrail is connected to the vertical railing 3 on the other side, a transmission assembly 5 for driving the movable guardrail to rise and fall is provided on the bottom side of the manure-leaking plate 1, and a trigger switch 6 for controlling the operation of the transmission assembly 5 is provided on the manure-leaking plate 1 located in the sow living area, and the trigger switch 6 is installed below the inclined plane to which the movable guardrail belongs, and the trigger switch 6 can be pressed down only when the sow is lying down. Among them, the fixed guardrail is arranged vertically and the movable guardrail is arranged obliquely, so that the cross section of the sow living area (the cross section in the length direction of the sow living area) can be a right-angle trapezoid.

[0024] In the present embodiment, vertically arranged strip holes 20 are provided on the vertical railing 3, and the movable guardrail includes a movable frame 7 movably connected to the vertical railing 3, and a plurality of bent partition rods 8 are fixedly installed on the bottom side of the movable frame 7, and the rectangular cross bar 21 of the movable frame 7 is loosely fitted in the strip hole 20; the transmission assembly 5 includes multiple fixed pulleys 22 and at least two trigger switches 6 arranged at intervals, and the head end of the steel cable 14 is connected to the trigger switch 6, and the steel cable 14 passes through the fixed pulley 22 and its tail end is connected to the rectangular cross bar 21. When all the trigger switches 6 are pressed down at the same time, the rectangular cross bar 21 is pulled up by the steel cable 14, thereby realizing the upward movement of the movable frame 7. At this time, the height between the lower end of the movable frame 7 and the surface of the manure-leaking board 1 is greater than the height of the piglets.
