Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pig raising apparatus for preventing a piglet from being killed by a parent pig.

[0002]

2. Description of the Related Art Conventionally, in pig farms, parent pigs and piglets are put in one fence for breeding.

[0003]

[Problems to be Solved by the Invention] When a parent pig and a piglet are raised in a single fence and raised, when the parent pig suddenly tries to lie down, the piglet becomes an underlay of the parent pig. There are many cases of crushing death. Especially when the fence is narrow, there is a problem that this probability becomes higher.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a pig breeding apparatus having a function of preventing the death of a piglet from being killed by a parent pig. It is a thing.

[0005]

In order to achieve the above object, the present invention provides an outer fence for accommodating piglets, which is connected to at least one side of an inner fence capable of accommodating parent pigs. At the border of the fence, only the piglets are provided with partitions that can freely enter and leave both fences, and a ventilation means is provided to send the wind to the feet of the parent pigs.

[0006]

[Function] When the parent pig is standing, if air is blown to the feet of the pig by the blowing means, the pig will dislike the wind and move to the outer fence, and will not approach the foot of the pig, so the pig will suddenly move away. Even if you lie down, the piglets will not die.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 and FIG. 2 show the whole pig breeding apparatus (1) having a function of preventing crush death of piglets.

The pig farming device (1) has a leg (2) and a ground (3).
A horizontal floor (4) made of wire mesh supported at a more appropriate height,
Inner fence (5) for housing parent pigs (A) standing on the floor (4) so that the plane shape is a long rectangular shape that is long in the front-back direction (the upper side in FIG. 1 is the front), Floor so that it is continuous on both sides of the fence (5)
(4) An outer fence (6) for accommodating a piglet (B) whose plane shape is erected on the top is provided.

The front-rear length, left-right width, and height of the inner fence (5) are the total length of the parent pig (A) so that the parent pig (A) cannot escape or reverse from the inner fence (5). It is set to be slightly larger than the trunk width and height when standing on four legs, the front and rear length of each outer fence (6) is the same as the inner fence (5), the left and right width is about half of the inner fence (5), And the height is slightly lower than the inner fence (5).

The inner fence which is the boundary between the inner fence (5) and the outer fence (6)
On both sides of (5), two horizontal partition rods (8) are erected on the middle part of the frame rod (7) formed by bending an iron pipe downward in a U shape, and the lower partition rods are installed. It is formed by installing a proper number of vertical partition rods (9) between the floor (4) and the floor (4) at appropriate intervals in the front-rear direction, and the partition rods (8) and the partition rods (9) are formed. By this, the piglet (B) can freely enter and leave both fences (5) and (6), but a partition that blocks passage of the parent pig (A) from the inner fence (5) to the outer fence (6). Are configured.

A bait box (11) having a handle (10) is detachably attached to the front surface of the inner fence (5), and a drop-down gate (12) is attached to the front surface of the outer fence (6). Is mounted so that it can be pulled out upward.

At the center of the front surface of the inner fence (5) and below the bait box (11), a cylindrical outlet (13) parallel to the partition rod (8), that is, facing in the front-rear direction. Is fixed, and the front end of this outlet (13) is connected to both fences (5) through the bellows pipe (14).
(6) It is connected to a well-known blower (15) installed in a proper place outside.

Thus, the blower (15), the bellows tube (14) and the outlet (13) form a blower means (16) for sending wind to the feet of the parent pig (A) when standing on four legs. .

(17) is provided at a position lower than the height when the parent pig (A) stands on four legs and higher than the height when the parent pig (A) is prone (or lying down). A well-known reflection type optical sensor fixed to the partition rod (8) on the upper stage of the fence (5) detects that the parent pig (A) is lying down and stops the operation of the blower means (16). To do.

The optical sensor (17) and the main switch (not shown) are connected in series between the blower (15) and a power source (not shown).

Next, the operation of this embodiment will be described. If the parent pig (A) is standing when the main switch is turned on, the optical sensor (17) will detect that and the optical sensor
The contact (not shown) in (17) is closed, the blower (15) is energized, and the blower (15) is operated.

When the blower (15) is activated, the blower (1
The air is blown from the 5) through the bellows pipe (14) to the outlet (13).
The outlet (13) has a cylindrical shape that is substantially parallel to the partition pipe (8), so the wind from the outlet (13) is almost at the center of the inner fence (5) and the parent pig (A). It is sent straight backwards through the feet of and is unlikely to spread to the outer fence (6).

Therefore, during blowing, the piglet (B) dislikes the wind and moves from the inner fence (5) over the partition to the outer fence (6) side, and below the abdomen of the parent pig (A). Since it rarely sneaks in, even if the parent pig (A) suddenly lays down in this state,
The piglets (B) are rarely killed by the parent pigs (A).

When the parent pig (A) lays down and its height becomes low, the optical sensor (17) detects that and the built-in contact opens, and the power supply to the blower (15) is stopped. . Then, the air blown from the outlet (13) is stopped, wasteful power consumption can be eliminated, and the parent pig (A) and the piglet (B) are not uncomfortable and the piglet (B) ) Is free to drink parent pig (A) milk.

In the present invention, for example, the outer fence (6)
Is provided only on one side of the inner fence (5), or the optical sensor (17) is of a type composed of a light emitting element and a light receiving element which are installed separately on both sides of the parent pig (A), or an optical sensor ( 17) instead of
Many variations and modifications are possible, such as using known ultrasonic sensors or other sensors.

[0021]

According to the present invention, the following effects can be obtained. (a) At the boundary between the inner fence and the outer fence, a partition that allows only piglets to enter and leave is provided, and a ventilation means is provided to blow air to the feet of the parent pig on the inner fence. I hate to move to the outer fence side and do not dive under the abdomen of the parent pig when standing, so even if the parent pig suddenly lays down, the piglet will not be killed by death (all claims Invention).

(B) The air outlet of the air blowing means is formed in a cylindrical shape parallel to the partition, and the air outlet is provided almost at the center of one end of the inner fence so that the air is concentrated only in the inner fence and does not diffuse into the outer fence. Therefore, it is possible to improve the efficiency of preventing crushing death of piglets (the invention according to claim 2). That is, if the blast diffuses into the outer fence as much as possible, the effect of eliminating piglets in the inner fence is weakened and the efficiency is reduced.

(C) The blower can be installed anywhere by connecting the blowout port and the blower with a bellows tube (the invention according to claim 3).

(D) By providing the outlet under the bait box, the bait box and the bellows tube do not interfere with the attachment and detachment of the bait box, and the bait box can be easily attached and detached.
Invention described).

(E) By providing a sensor for detecting that the parent pig is lying down and stopping the operation of the blowing means,
It is possible to eliminate wasteful power consumption and eliminate discomfort of parent pigs and piglets (the invention according to claim 5).
