Description

[Detailed description of the invention] The present invention is a pig farrowing fence, in particular, adjusts the length of the farrowing fence according to the body length of the parent pigs to maintain a constant position for the parent pigs to excrete feces, and also allows them to escape by turning back and forth. This invention relates to a vertically split type pig farrowing fence equipped with a movable upper farrowing fence that prevents the above.

Conventionally, in order to prevent piglets from being crushed to death or injured by parent pigs after parturition, parent pigs are kept in a farrowing enclosure for a certain period of time and reared. An example of such a farrowing fence is one such as that described in Japanese Patent Application Laid-open No. 52-30674, in which the width, length, and height of the farrowing fence are fixed, and the feeding box is also fixed at a fixed position in the front part. It has been known. In this type of system, the position of feces excretion is not constant depending on the size of the parent pig.
There is a problem in that the excrement cannot be removed and collected without dropping it onto the floor inside the fence, resulting in contamination of the floor inside the fence. As a result, the inside of the enclosure becomes unsanitary and causes diarrhea etc. in the piglets. In addition, as a solution to the above problem, we installed a manure receiving plate inside the fence that can swing and adjust its position to follow the buttocks of the parent pigs, so that even if the size of the parent pigs is different, the manure and urine will fall onto the floor inside the fence. There are also known devices that allow exclusion and collection without causing any damage (for example, Japanese Utility Model Application Publication No. 151796/1983). In all of these conventional techniques, the height of the fence is uniform and constant over the entire length of the fence. Therefore, in order to prevent the pigs from jumping out of the fence, the height of the fence must be made quite high, or it must be made slightly taller than the parent pigs and covered above with fence rods. Therefore, it is difficult to directly contact the parent pigs from outside the fence, making it difficult to perform breeding management such as injections, for example.

However, the pigs are prevented from moving back and forth;
If the height is suppressed from the head to a certain range of more than half the body length, it will not be possible to turn around inside the fence, and therefore will not be able to escape from above the fence. Therefore, by making that certain range higher than the height of the mother pig and restraining the upper part, the height of the other parts can be made lower than the height of the mother pig and the upper part can be opened. Based on this fact, the height of the farrowing fence is increased only in a certain range from the head of the parent pig, and the top is covered with fence rods, and the height of the other parts is made lower. has also been proposed previously. However, in the previously proposed farrowing fence, the fence frame is fixed as one piece, and the position of the feeding box is adjusted in accordance with the size of the parent pigs. Therefore, if the parent pigs are small, the feeding box is placed inside the fence, and the ratio of the area covered above the shelf to the body length of the parent pigs becomes shorter. As a result, the parent pig may be able to turn over and escape from the rear part where the upper part is not covered.

In addition, in the conventional farrowing fence described above, in order to adjust the position of the feeder to match the pig's body length, the feeding box must be attached and fixed along the fence frame inside the farrowing fence, so it takes time to adjust the position, and It was dangerous for the pigs to get their wrists pinched or attacked by the parent pigs.

The present invention was devised in view of the above-mentioned drawbacks of the conventional technology.The present invention adjusts the length of the farrowing fence according to the body length of the parent pig to keep the position of the parent pig's excrement constant, and the height of the farrowing fence is Even if you do not increase the overall brightness,
The purpose of the present invention is to provide a farrowing fence that can prevent parent pigs from turning over and escape, and also allows easy adjustment of the position of a feeding box.

In order to achieve the above object, the present invention divides the farrowing fence into upper and lower halves, with the lower farrowing fence being longer than the pig's body length, and the upper farrowing fence being shorter than the pig's body length. The upper calving fence is installed on the lower calving fence so that it can be moved back and forth. Then, by attaching a feeding box in front of the upper farrowing fence and adjusting the movement of the upper farrowing fence according to the body length of the parent pigs,
The feeding box also moves at the same time, and the space within the farrowing fence can be divided and fixed according to the body length of the parent pigs. Therefore, the length of the farrowing fence is divided according to the body length of the parent pigs based on the rear part of the farrowing fence, so that the position of the parent pig's feces excretion is always at a constant position. Then,
By providing a suitable removal means such as a feces receiving chute at the feces excretion position, it is possible to prevent feces from contaminating the inside of the fence. In addition, even if the space inside the farrowing fence changes, the upper farrowing fence that covers the top of the space is always the same length, so even small parent pigs can be sufficiently covered with the upper part of the farrowing fence. It is possible to prevent the pig from turning around and escaping. In addition, the height of the fence is low near where the buttocks of the parent pigs are located and the upper part is open, making it easy to manage the rearing of the parent pigs.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The calving fence of the present invention is composed of a lower calving fence 1 and an upper calving fence 2 provided on the upper part thereof so as to be movable in the longitudinal direction.

As shown in the figure, the lower calving fence 1 consists of left and right fence side frames 4, 4, and each fence side frame 4, 4 is connected between the front and rear pillars 5, 6 by upper and lower two stages of fence frame rods 7, 8. It is configured as follows. The upper fence frame rod 7 is provided so as to be located on the inner side of the fence than the pillars 5 and 6 as shown in the figure.

The fence side frames 4, 4 having the above-mentioned configuration are arranged in front and back at intervals that allow the parent pigs to lie down in the longitudinal direction, and are established on the ground or floor surface 10 using the front and rear pillars 5, 6, respectively. and install it to constitute the lower calving fence 1. At this time, the interval 11 between the floor surface 10 and the lower fence frame rod 8 is set at such an interval that the piglets can enter and exit the fence and receive milk.

On the other hand, the upper part calving fence 2 is constructed of a front and a rear part erected on a sliding body consisting of channel-shaped steel rods 14, 14 having a U-shaped cross section and slidably fitted to the upper fence frame rod 7 of the lower part calving fence 1. The gate-shaped rods 12 and 13 are connected by a plurality of connecting rods 15.

The length of the upper farrowing fence 2 is shorter than the lower farrowing fence 1, and is long enough to prevent the mother pig from turning over because its upper part is obstructed by the connecting rod 15 disposed above the fence 2. is set to . At predetermined positions of the upper fence frame rods 7, 7 of the lower birthing fence 1, through which the channel steels 14, 14 are slidably guided, there are screw holes 1 for positioning the upper birthing fence 2.
6, 16... are bored, and the channel type steel 1
4 and 14 have holes 18 into which setscrew rods 17 and 17 are fitted at appropriate positions to slide over the screw holes 16 and 16.
is drilled. As a result, the upper farrowing fence 2 is moved along the upper fence frame rods 7, 7 according to the body length of the mother pig, and is positioned and fixed with the setscrew rods 17, 17, so that the upper farrowing fence 2 can be moved inadvertently by the pig. 2 from sliding.

In the above embodiment, the channel-shaped steel rods 14, 14 having a U-shaped cross section were used as the sliding guide means for the upper parturition fence 2, but the sliding guide means is not limited to this, and for example, a gate-shaped rod may be used. Appropriate means can be adopted, such as fixing channel-shaped or curved short pieces that fit with the upper fence frame rods 7 to the lower ends of each of the gateposts 12 and 13. Also, the means of fixing the position is not limited to screw rods.
An appropriate one can be adopted.

Further, in the above embodiment, the upper fence frame rod 7 and the pillars 5, 6 of the lower calving fence 1 are constructed by bending one cylindrical pipe, and the lower fence frame rod 8 is welded and fixed thereto. However, as shown in Fig. 8, each can be constructed from a separate cylindrical pipe, and the lower fence frame rods 8 may be attached adjustable so that the height can be adjusted according to the size of the piglet. .

Figures 5 to 8 show the farrowing fence constructed as described above, with a feeding box 20, a tail door 21, and a dung chute 22.
An example of the state in which the is attached is shown.

The feeding box 20 is attached to the front gate-shaped rod 1 of the upper calving fence 2.
2 through an appropriate bracket, and as shown in the figure, the feeding port 19 faces inward of the farrowing fence, and moves along the longitudinal direction of the lower farrowing fence integrally with the upper farrowing fence 2. I'm starting to be able to do it.
The feeding box 17 also serves to block the front opening of the farrowing fence 2 to prevent the parent pigs from escaping.

The butt door 21 is connected to the rear pillar 6 of the lower birthing fence 1,
A butt stopper frame 23, 23 that supports the butt of the parent pig during excretion is attached to the door frame rotatably attached to one side of the door frame 6.
It is configured such that it protrudes inward from the fence. A excrement receiving chute 2 is installed between the butt stop frames 23 and 23.
2 is fixed, and the manure excreted by the parent pigs is discharged to a fixed position outside the fence. In addition, 2
4 is a stopper for the butt door 21.

The calving fence constructed as described above is used in the following manner.

Open the butt door 21, move the upper farrowing fence 2 forward along the lower farrowing fence 1 to introduce the parent pig, and after introduction, move the position of the upper farrowing fence 2 appropriately according to the body length of the parent pig. Adjust the set screw rod 17 through the screw hole 18 of the channel steel 14 to lower the lower calving fence 1.
The position of the upper birthing fence 2 is fixed by screwing it into the screw hole 16 of the upper frame rod 7.

In this case, since the feeding box 20 is also moved and fixed, there is no need to insert a hand into the farrowing fence to adjust the movement as in the conventional method, and the adjustment can be done easily and without danger. Further, since the space is adjusted according to the body length of the parent pig, the butt of the parent pig is always located on the butt stopper frame 23. Therefore, the mother pig excretes while sitting on the butt stopper frame 23, and the excrement is removed to the outside via the excrement receiving chute 22, so that the inside of the farrowing fence is not soiled.

As described above, according to the present invention, excrement and urine can be removed and collected while keeping the excretion position of the parent pigs constant, which prevents contamination of the floor inside the fence and prevents the occurrence of diarrhea etc. in piglets. It is extremely useful and hygienic. In addition, simply by adjusting the movement of the upper farrowing fence according to the body length of the mother pig, the feed box is also moved and adjusted, so that the feed box can be easily adjusted without the risk of moving the feed box as in the conventional method. Moreover, even if the space inside the fence is adjusted, the entire length of the upper farrowing fence always covers the upper part of the fence, so even small parent pigs can be prevented from turning around and escaping. Therefore, there is no need to increase the height of the farrowing fence over its entire length, so it can be formed compactly. The area near where the parent pig's buttocks are located is
Since the height of the fence is low and the top is open, it is easy to manage breeding of parent pigs.
