Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to equipment for preventing accidental death of a piglet, which is apt to occur by mistake when a piglet is breast-feeding a newborn piglet.

[0002]

[Conventional technique] Immediately after giving birth, sows are kept in a cage according to their body shape so that they will not move and walk. That is, the sows in the cage are either standing up, lying down and resting, or lying down and breastfeeding. When there is a need for breastfeeding while standing up, the sows lie on their backs without any hesitation. At this time, the piglet escapes late and is killed under the mother pig. No special measures were taken against this crushing death, and it was up to the consequences. As a result, the number of newborn piglet deaths has reached a considerable number.

[0003]

[Problems to be Solved by the Invention] When a mother pig enters a lactating activity, it lays down for a long time, and during that time, the piglet is informed of the lying behavior and a device for safely evacuating the piglet is provided.

[0004]

[Means for Solving the Problems] A pressure death preventer for piglets, which has been solved based on the above problems, is composed of a pair of left and right equipment.
Is an example thereof, and is a plan view of the equipment for the right side, and FIG. 2 is a right side view thereof.

In the figure, a piglet crush prevention device comprises a fixed frame formed of a pipe and a rotary frame, and the fixed frame is a U-shaped frame.
It is composed of (1) and pivot bearing (2) . U shape on fixed frame
The hook (3) is welded to the frame and the nut (4) is welded to the pivot bearing.
An L-shaped hook (5) is screwed onto the nut (4). The rotating frame consists of a pivot shaft (6) rotatably inserted in a pivot bearing and a sliding part (7), and the sliding part has a slope with respect to the pivot shaft .
However, it is formed like a wedge, and one end of the chain (8) is attached near its widest width, and the other end of the chain can be hung on the hook (3) on the fixed frame. There is. Remove the chain, rotate the rotating frame 180 degrees, and change the direction of the L-shaped hook in the opposite direction to obtain the left side equipment.

[0006]

[Operation / Embodiment] The operation will be described below together with the embodiment.

A wire is used in place of the chain (8) of the piglet pressure suppression device shown in FIGS. 1 and 2, and the wire is attached to the cage of the sow as shown in FIG. In FIG. 3, right pressure dead preventer is attach in the state shown in FIG. 1, the left side of the pressure dead preventer rotates the rotary frame 180, toward the L-shaped hooks (5) in the opposite direction It was replaced and attached. When fixing the fixed frame to the cage, hang the L-shaped hook (5) on the horizontal pipe of the cage, and use a rope or U-bolt at an appropriate point where the U-shaped frame (1) and the cage pipe come into contact. Just fasten. Fig. 4 is an oblique view showing an example of this, and the horizontal pipe (9) of the cage
And the U-shaped frame intersect. The mounting height of the pivot bearing (2) is approximately in the vicinity of the knees of the mother pig and in the longitudinal position.
As for the placement, the widest part of the sliding part (7) is fitted near the buttocks of the mother pig . The L-shaped hook has a U-shaped frame.
To attach to the pipe, but to give a flight
When the height of the pivot bearing does not match near the socks above the mother's knee,
Is a connecting metal such as a U-shaped bolt regardless of the L-shaped hook
Attach with just the tools.

[0008] Now, when the mother pig tries to lie down for breastfeeding, the wide parts of the left and right sliding parts (7) interfere and cannot lie down. For this reason, the mother pig begins to shake the buttocks left and right violently. Then, since the sliding portion (7) is inclined, the rotating frame is pushed backward. At this time, since the rotary frame is pulled by the fixed frame by the chain (8), the left and right sliding parts are raised with the pivot shaft (6) as the rotary shaft. When the sliding part is lifted up, the mother pig enters under it and lies sideways. During this movement, the piglets evacuate quickly and never under the mother pig. It should be noted that when standing up, the buttocks only push up the sliding portion.

In this example, an L-shaped hook (5) is screwed to a nut welded to a pivot bearing (2), hung on a horizontal pipe of a cage, and then fastened with a rope or a U-shaped bolt. However, even if the L-shaped hook is provided at an appropriate position of the U-shaped frame (1), the same attachment effect can be obtained.

[0010]

【Effects of the Invention】 ○ 1 In the past, it was not possible to keep an eye on the newborn piglets from beginning to end so as not to be crushed by death. However, the present invention eliminates such a need.

[0012] Since there is no accident such that a piglet is killed by pressure even if it is left alone, it becomes easier to manage pigs and the production cost can be reduced accordingly.
