Description

[Detailed Description of the Invention] The present invention relates to the improvement of a raised-bed type farrowing pen having leg pieces among pig farrowing pens used from the birth of a mother pig until the weaning of piglets.

Conventionally, in order to prevent piglets from being crushed to death and to improve suckling, piglet stalls were formed to allow piglets to move freely on both sides of the sow stall, which was formed to restrict the movement of the sow. Among the pig farrowing pens that are connected to each other and have a partitioned farrowing fence installed at the border between the mother pig stall and the piglet stall to allow free suckling, in a raised farrowing pen, The leg pieces supporting the farrowing chamber were formed integrally with the farrowing fence.

However, with this conventional structure, the legs must be made of rigid and strong steel in order to support the load of the farrowing pen, pigs, etc. Therefore, the farrowing fence is also integrally made of the same steel. Must. As a result, the weight of the farrowing fence increases, which not only makes it difficult to assemble the farrowing pen by attaching the floor frames and doors of the mother and piglet stalls to the farrowing fence, but also causes the legs to rust. If the fence becomes brittle (the legs are easily rusted because it is in contact with the ground or the bottom end is buried), it has to be replaced every time the farrowing fence is used, which is a disadvantage in terms of cost and effort.

The present invention has been made in view of the above-mentioned conventional drawbacks, and aims to provide a farrowing pen for pigs that has a farrowing fence that is significantly lighter in weight and is easy to assemble.

For this reason, in the present invention, the farrowing stall is provided with a connecting plate having leg pieces fixed to the lower end by welding at the boundary between the mother sow stall and the piglet stall on the front and rear sides of the farrowing stall, and the lower end of the connecting plate The floor frames of the sow stall and suckling stall are fixed with bolts, a door etc. is pivotally attached to the side of the connecting plate, and the lower end of the farrowing fence is fixed with bolts to the top of the connecting plate. By doing so, the intended purpose was achieved.

The present invention will be described below with reference to illustrative embodiments.

A is a raised-floor farrowing pen for pigs, which includes a sow stall a, piglet stalls b arranged on the left and right sides of the sow stall a,
A connecting plate 11 is interposed at the boundary between the mother pig stall a and the left and right piglet stalls b and b' on the front and rear surfaces of the farrowing stall A, and the lower end of the connecting plate 11 at both left and right ends of the front and rear of the floor frame 12 of the mother pig stall a,
The front and rear ends of the floor frames 13, 13' of the piglet stalls b, b' are fixed with bolts 14. Numeral 15 is a leg member that supports the other end of the front and rear sides of the floor frames 13 and 13' of the piglet stalls b and b'.

The connecting plate 11 is made of channel steel and has a U-shaped cross section that opens outward, and has a leg piece made of a rigid and strong steel material at the lower end of the concave outer surface. 16 is fixed by welding. Further, between the front and back of the upper part of the connecting plate 11, a farrowing fence 17 that partitions the mother pig stall a and the piglet stalls b and b' so that they can suckle is installed horizontally, and the lower ends of the farrowing fences 17 are connected to the connecting plate 11 with bolts 18, respectively. It is fixed by. Reference numeral 19 denotes a calving fence support rod that connects the upper rails 17a of the left and right calving fences 17.

Further, a lower fence 20 is horizontally installed between the front and rear of the connecting plate 11 below the birthing fence 17, and a butt stop is provided between the lower fence 20 and the rear right and left sides of the lower fence 17b of the birthing fence 17. A pipe 21 is laid across.

It is preferable that a plurality of bolt holes 18' and 11' be vertically formed in the connecting plate 11 so that the heights of the delivery fence 17 and the lower fence 20 can be adjusted.
In addition, in the embodiment of the present invention, the mother pig stall a is attached to the connecting plate 11.
The floor frame 12 and the floor frames 13, 13' of piglet stalls b and b' are bolted together and the leg pieces 16 are welded together, but the present invention is not limited to this, and both may be bolted together or welded together. good.

Reference numeral 22 denotes a feeding tank door provided on the front side of the sow stall a, one side of which is pivotally connected to one of the connecting plates 11 via a hinge 23 so as to be openable and closable, and the other side is a free end. It is configured to be removably locked to the other side of the connecting plate 11 by a locking device (not shown). Reference numeral 24 denotes a sow stall door provided at the rear side of the sow stall a, one side of which is connected to the connecting plate 11.
is pivotally connected to one side of the connecting plate 11 via a hinge 26 so as to be openable and closable, the other side is a free end, and the connecting plate 11 is detachably locked to the other side of the connecting plate 11 by a locking device (not shown). There is. Reference numeral 27 denotes a feed tank detachably attached to the feed tank door.

Reference numerals 28 and 28' denote piglet stall doors provided at the front and rear of the piglet stalls b and b, which are removably attached to attachment pieces 29 fixed to the connecting plate 11 and the leg member 15. 30 is a farrowing bed fixed to the floor frame 12 of the mother pig stall a, and 31 and 31' are piglet stall floors fixed to the floor frames 13 and 13' of the piglet stalls b and b'.

As described above, according to the present invention, the leg pieces that support the farrowing stall and the farrowing fence that partitions the mother sow stall and the piglet stall to allow suckling are formed separately and are fixed to the connecting plate, respectively. The calving fence does not need to be formed from a rigid steel material similar to the leg pieces, and can be formed from a relatively lightweight steel material such as a thin-walled pipe. We were able to significantly reduce the weight of the fence.

In addition, according to the present invention, by setting the connecting plate to which the leg pieces are fixed in a predetermined position, it is not only possible to assemble each pig stall and farrowing fence easily, but also to attach doors etc. using the conventional legs. This has the advantage that it can be installed more easily and reliably than when the fence and the farrowing fence are attached to an integrated structure.
