Description

The invention of the present application relates to a stanchion for tethering livestock, and in particular, livestock such as dairy cows are tethered to the stanchion in order to eat the feed supplied, and when they are eating the feed, they fall asleep and are injured in the neck. Even if the head and neck cannot be pulled out from the stanchion while the stanchion is moored, the head and neck can be pulled out from the stanchion with a simple operation without disassembling the stanchion. , relates to a livestock tethering stanchion which allows the livestock to be pulled out of the stanchion and released into a free state.

In free-stall cowsheds, feeding areas are set up along passages where dairy cows can freely come and go. A series of tethering devices are provided along the path for use such as when eating feed provided with .
When the cows eat the feed supplied to the feeding area, they stand in the aisle, put their heads out of the windows provided in the stanchions, and interact with the adjacent cows. Instead, they are able to keep quiet and eat their feed.

There are various types of stanchions, but basically, a pair of fixed vertical fence rods are installed between an upper frame pipe and a lower frame pipe for connecting multiple stanchions in a row. , are provided by fixing their upper and lower ends to these frame pipes, and between the pair of fixed vertical fence rods, for example, one bent fence rod bent in a dogleg shape, It is provided close to either the left or right fixed vertical fence rod side, and at the bent part of this doglegged bent fence rod, the rotating vertical fence rod is at the center in the length direction or slightly more than that. In the downward position, it is rotatably supported to form a single stanchion.

In this case, the upper edge of the dogleg-shaped bent fence rod is in contact with the upper edge or near the upper edge of one of the fixed vertical fence rods on the gathered side, and the upper part thereof or its vicinity While it is fixed to the frame pipe, the lower side of the dogleg-shaped bent fence rod is erected vertically or inclined toward the one fixed vertical fence rod, and its lower end is attached to the lower part. Many of them are structured so as to be in contact with and fixed to the lower end of the frame pipe or one of the fixed vertical rails (Patent Documents 1 to 4).

On the other hand, in the stanchion conventionally used by the present applicant, as shown in FIG. However, an inverted L-shaped bent fence rod 07 shortened to about half the height of the fixed vertical fence rods 04 and 05 is used, and the inverted L-shaped bent fence rod 07 is bent. A rotating vertical fence rod 06 is rotatably supported on a pivot 08 provided in the section at a position slightly lower than the center in the longitudinal direction of the stanchion 01. It is designed to be
In this case, the tip side of the horizontal side "one" of the inverted L-shape is fixed to one of the fixed vertical fence rods 05 on the side where the bent fence rod 07 is provided, and the vertical side of the inverted L-shape "1" is fixed to the lower frame pipe 03. 02 is the upper frame pipe.

The one described in Patent Document 5 is also common to the conventional example of the present applicant in that it uses an inverted L-shaped bent fence rod. In addition, the one described in Patent Document 6 is different from the applicant's conventional example in that the vertical side "1" of the inverted L-shape is missing, but it is close to this, and is also the prior art of the invention of the present application. A pivot means for an exemplary pivoting stanchion rod to indicate level is disclosed.
Regarding these conventional stanchions, what is called a "fence rod" here is referred to as a "partition post" in Patent Documents 1 and 6, and as a "fence bar" in Patent Documents 2 to 4. In addition, in some documents, "fence rods" and "fence pipes" are used, but in reality, even those described as "partition posts", "fence rods", and "fence rods" are In many cases, it is believed that metal "fence pipes" will be used.
In the description of the invention of the present application, the term "fence rod" is used as an expression that can include all of these.

In such a conventional stanchion, for some reason (its own weight, pressure from the head or neck of the dairy cow, artificial operation, etc.), the vertical fence rod is bent into a dogleg shape. When it is turned and knocked down so as to follow the upper side (Patent Documents 1 to 4), or when it is turned and knocked down so that the upper end collides with the upper end of one of the fixed vertical fence rods (Patent Documents 5 and 6, conventional examples of the present applicant) disclose a relatively large inverted triangular space ( window) is formed.

Therefore, a dairy cow inserts its head from the upper expanded part of this inverted triangle space and protrudes forward to eat the feed supplied on the floor of the feeding area in the lower front. When the head and neck are lowered, the neck pushes the lower part of the tilted rotating vertical fence rod, and the vertical rotating fence rod is rotated in the direction to stand up, maintaining a vertical posture. become. In many stanchions, the pivoting vertical fence rod is locked in this position (see, for example, FIG. 2 of U.S. Pat. Therefore, the dairy cow continues to eat the feed in such a locked state of the rotating vertical fence rod.

In this way, in a state in which the rotating vertical fence rod is locked while maintaining a vertical posture, the rotating vertical fence rod is aligned parallel to the other fixed vertical fence rod, so that the cows can The upwardly widening inverted triangular space (window) through which the head could be put in and out has now disappeared.
Therefore, even if the cow finishes eating the feed, pulls out its head from the window of the stanchion, and tries to move around freely, the cow will not be able to move around freely with these two parallel rotating vertical bars and the other fixed. It is only possible to move its neck up and down in the vertically elongated space formed between the vertical fence rods. You can't get your head out of it and return to a free, liberated state.

By the way, even when the rotating vertical fence rod is locked in a vertical position and the cows are placed in a state where they can eat the supplied feed, the cows Sometimes I fall asleep in the stanchion.
In addition, even when the time (feeding time) in which dairy cows can eat feed ends and the time has come for humans to unlock the rotating vertical fence rods, they forget to unlock them and leave the cows out of the barn. This is often neglected due to human error such as leaving the cow, and even in such cases, the cow sometimes falls asleep in the stanchion without being able to get out of the same position. .

If such a thing occurs, the life of the dairy cow may be involved and it may cause injury. It is necessary to return the cow to a state in which an inverted triangular space can be formed, hold the head and neck of the dairy cow, and move it to a large space above the inverted triangular space, but the weight is It is impossible to hold the head and neck of a dairy cow weighing 800 kg, so I had no choice but to use a rotating vertical fence rod as described in Patent Document 2. The rotatable vertical fence rod must be removed by, for example, loosening the bolt-nut fastening structure of the portion rotatably supported on the bent portion of the curved fence rod. The space surrounding the head and neck of the cow is expanded laterally so that they can be moved to the left and right of the window of the stanchion, and back and forth. I was able to pull it out of the stanchion and set it free.
Therefore, when the cow is placed in a state where it can eat the supplied feed, or even when it is not placed in such a state, the lock of the rotating vertical fence rod can be released due to human error. If the cow falls asleep in the stanchion without being able to get out of the same position, the head and neck of the cow are pulled out of the stanchion, and the cow is pulled out of the stanchion to release it into a free state. was not easy and took time.

Therefore, in Patent Document 3, in order to solve such a problem, an inverted triangular space (window portion) that expands upward is formed in cooperation with the rotating vertical fence rod. A U-shaped auxiliary vertical fence rod is rotatably attached to the fixed vertical fence rod, and the rotating vertical fence rod cooperates with this auxiliary vertical fence rod to form an inverted triangular shape that is expanded upward. In addition to forming a space (window), the dairy cow puts its neck in the vertically elongated space formed between the two parallel rotating vertical fence rods and the auxiliary vertical fence rod. If the user falls asleep while eating feed, rotate the auxiliary vertical fence rod 90 degrees around the other fixed vertical fence rod to widen the horizontal width of the vertically elongated space. By doing so, the head and neck of the cow can be moved in the lateral and longitudinal directions through the window of the stanchion, and then the cow is pulled out of the stanchion and released into a free state. .

However, in this case, in order to rotate the auxiliary vertical fence rod 90 degrees around the other fixed vertical fence rod, the auxiliary vertical fence rod is once lifted upward, and the engagement between the pin c and the notch d is performed. After releasing the joint, rotate it 90 degrees in any direction while observing the posture of the dairy cow, then lower the auxiliary vertical fence rod in this state, and align the pin c and the other notch d'. In addition to having to prepare a special shaped vertical fence rod called a U-shaped auxiliary vertical fence rod, to widen the horizontal width of the vertically elongated space, In addition, it is hard to say that the troublesome work has been completely eliminated.
It should be noted that the problems described above can occur not only in the case of dairy cows, but also in the case of beef cattle and horses, and a solution has been desired.

To provide a stanchion for mooring livestock with a simple structure capable of pulling out the livestock from the stanchion and releasing the livestock in a free state by simple work and in a short time even when the livestock is sleeping while eating. The task is to provide

The problems described above are solved by the following inventions described in the claims of the present application.
That is, the invention described in claim 1 is used for mooring livestock when the livestock is fed with feed, etc., and the upper frame pipe and the lower frame pipe are separated by a predetermined interval. , a pair of left and right fixed vertical fence rods are provided by fixing their upper and lower ends to the upper frame pipe and the lower frame pipe, respectively. The fence rod is provided rotatably between a position in which it stands vertically and a position in which one of the pair of left and right fixed vertical fence rods falls toward one of the fixed vertical fence rods. The vertical fence rod has a substantially central portion or a slightly lower portion thereof pivoted to the tip of a relatively short first auxiliary horizontal fence rod horizontally attached to the one fixed vertical fence rod. A livestock which is freely pivoted and provided with a locking means capable of locking said pivotable vertical fence rod in said vertically upright position. In the mooring stanchion, the first auxiliary horizontal fence rod is fixed horizontally to the one fixed vertical fence rod and in the opposite direction to the first auxiliary horizontal fence rod. The stanchion for mooring livestock is characterized in that it is fitted and attached to the inside of the second auxiliary horizontal fence rod so as to be movable forward and backward.

In addition, the invention described in claim 2 is characterized in that a relatively short auxiliary vertical fence rod is fixedly attached downward to the tip of the first auxiliary horizontal fence rod. A stanchion for mooring livestock according to claim 1.

Further, in the invention described in claim 3, at least one fixed vertical fence rod is provided between the upper frame pipe and the lower frame pipe, adjacent to the one fixed vertical fence rod, The upper and lower ends thereof are fixed to the upper frame pipe and the lower frame pipe, respectively, and the left end side of the second auxiliary horizontal fence rod is fixed to and supported by the other fixed vertical fence rod. The stanchion for mooring livestock according to claim 1 or 2, characterized in that the stanchion is

Further, in the invention described in claim 4, at least one of the fixed vertical fence rods, the first auxiliary horizontal fence rods and the second auxiliary horizontal fence rods has a rectangular cross-sectional shape. 4. The stanchion for mooring livestock according to any one of claims 1 to 3, characterized in that the stanchion is made by bending the stanchion to improve strength.

Further, according to the invention described in claim 5, the first auxiliary horizontal fence rod is arranged inside the second auxiliary horizontal fence rod so that the forward/backward position can be switched in a plurality of stages, 5. The stanchion for mooring livestock according to any one of claims 1 to 4, wherein the stanchion is attached so as to be movable forward and backward.

Since the invention of the present application is configured as described above, the following effects can be obtained.
A stanchion for mooring livestock according to the invention of the present application includes a pair of left and right fixed vertical fence rods, which are arranged at a predetermined distance between an upper frame pipe and a lower frame pipe, and which are connected to the upper frame by their upper and lower ends. It is fixed to the pipe and the lower frame pipe, respectively, and between the pair of left and right fixed vertical fence rods, the rotating vertical fence rod is vertically erected and the left and right fixed vertical fence rod Between the position that fell to one of the fixed vertical fence rods side, it is provided rotatably, and the rotating vertical fence rod has a substantially central part or a slightly lower part than one When it is rotatably supported on the tip of a relatively short first auxiliary horizontal fence rod that is horizontally attached to the fixed vertical fence rod, and the rotating vertical fence rod is in a vertically upright position. , in a stanchion provided with a locking means capable of locking the rotating vertical fence rod in this position, the first auxiliary horizontal fence rod is horizontally attached to one of the fixed vertical fence rods and the first It is fitted and attached so as to be movable forward and backward inside a second auxiliary horizontal fence rod fixedly attached in the opposite direction to the auxiliary horizontal fence rod.
As a result, when the rotating vertical fence rod rotates toward one of the fixed vertical fence rods and falls down, the upper part formed between the rotating vertical fence rod and the other fixed vertical fence rod expands. When a livestock such as a dairy cow inserts its head and neck into the space to eat the supplied feed and lowers it, the neck pushes the lower part of the rotating vertical fence rod, When the rotating vertical fence rod rotates in the direction to stand up vertically and is locked at that position, and in this state, if the livestock falls asleep while eating feed, or if the livestock eats feed Even if the time during which they can eat (feeding time) has ended and the livestock has not eaten the feed, the lock of the rotating vertical fence rod is not unlocked due to human error, causing the livestock to fall out of the same position. When the user falls asleep without being able to get out, the lock is released, the first auxiliary horizontal fence rod is retreated inside the second auxiliary horizontal fence rod, and the movement of this retreat is interlocked. Then, by retreating the rotating vertical fence rod toward one of the fixed vertical fence rods, the space surrounding the neck of the livestock is expanded in the horizontal direction, and the head and neck of the livestock are extracted from this space, Livestock can be pulled out of this space and set free.
As a result, compared to the stanchion of the conventional structure, the first auxiliary horizontal fence rod and the rotating vertical fence rod are integrally retracted toward one of the fixed vertical fence rods. It is possible to pull out the sleeping livestock from the stanchion in a short period of time and release them to a free state. Chung can be obtained, and the effect is extremely large.

In addition, since a relatively short auxiliary vertical fence rod is fixedly attached downward to the tip of the first auxiliary horizontal fence rod, the first auxiliary horizontal fence rod and the turning movement can be achieved with a simple structure. It is possible to prevent cows from putting their heads and necks in and out of the space below the vertical fence rods.

Also, between the upper frame pipe and the lower frame pipe, adjacent to one of the fixed vertical fence rods, at least another fixed vertical fence rod has its upper and lower ends between the upper frame pipe and the lower frame pipe. Since the left end side of the second auxiliary horizontal fence rod is fixed to and supported by this other fixed vertical fence rod, the rotating vertical fence rod and the first auxiliary horizontal fence rod are fixed to each other. It is possible to reinforce the structural part (one fixed vertical fence rod) that supports the fence rod and the second auxiliary horizontal fence rod.

In addition, since at least one of the fixed vertical fence rods, the first auxiliary horizontal fence rods and the second auxiliary horizontal fence rods has a rectangular cross-sectional shape, their strength can be improved. .

Furthermore, the first auxiliary horizontal fence rod is fitted and attached to the inside of the second auxiliary horizontal fence rod so as to be able to switch its forward/backward position in a plurality of stages so that it can move back and forth. , Depending on the size of the neck according to the age of the livestock, when the livestock is eating the supplied feed, the rotation vertical fence rod and the other fixed vertical fence rod surround the neck of the livestock. The size of the space formed between them can be set to an appropriate size. It is possible to prevent unexpected actions such as extracting the head and neck, and it is possible to manage livestock feeding according to the work schedule, thereby improving work efficiency.
In addition, commercially available stanchions are made in different sizes for calves and parent cows, and it is not possible for the breeder to freely change the room of the cow or change the size of the breeding cow. Since the stanchion is constructed as described above, this problem can also be solved, and there is a great advantage for farmers raising wagyu beef in that it can be dealt with without replacing the stanchion itself.
Moreover, when livestock including young livestock fall asleep, the above-described extremely large effect can be exhibited in the same manner.

(Example)
Next, an embodiment of a stanchion for mooring livestock according to the invention of the present application will be described in detail with reference to the drawings.
In this embodiment, a dairy cow is taken as an example of livestock. The stanchion for mooring dairy cows of the present embodiment (hereinafter simply referred to as "stanchion") is mainly used for mooring dairy cows in the barn when they eat the supplied feed. be done. Thus, by tethering cows when they eat feed, a plurality of cows can quietly eat feed without interfering with adjacent cows.
Here, for a plurality of dairy cows, a plurality of such stanchions are connected in a row, and the lock mechanism of the rotating vertical fence rod provided for each stanchion is operated at one point at one time. So, what is called interlocking stanchions that can be done at the same time is also often used. The stanchions of this embodiment are also part of such interlocking stanchions.

(overall structure)
First, the overall structure of the stanchion of this embodiment will be described in detail with reference to FIG.
The stanchion 1 of this embodiment, as shown in FIG. 1, has an upper frame pipe 2 and a lower frame pipe 3, which serve as upper and lower frames of the interlocking stanchion, so that the cow's head can enter and exit between the upper frame pipe 2 and the lower frame pipe 3. A pair of left and right fixed vertical fence rods 4, 5 are provided with their upper and lower ends fixed to the upper frame pipe 2 and the lower frame pipe 3, respectively.

Between the pair of left and right fixed vertical fence rods 4 and 5, the rotating vertical fence rod 6 stands up vertically (see FIG. 2), and the left and right pair of fixed vertical fence rods 4 and 5 (in this embodiment, the fixed vertical fence rod 5 on the left side in FIG. 1).
In this case, one (left) fixed vertical fence rod 5 is made of a pipe with a rectangular cross section as opposed to the other (right) fixed vertical fence rod 4 made of a circular pipe, and strength is improved. ing.

Here, the rotating vertical fence rod 6 has a relatively short first auxiliary rod attached horizontally to one of the fixed vertical fence rods 5 at a substantially central portion in its longitudinal direction or a slightly lower portion thereof. It is rotatably supported on a pivot 8 passed through the tip of the horizontal fence rod 7 . It should be noted that this first auxiliary horizontal fence rod 7 is also made of a tube with a square cross section, like the one fixed vertical fence rod 5 .
Locking means (to be described later) is provided to lock the vertical rotatable fence rod 6 at a vertically upright position.

(Installation of first auxiliary horizontal fence rod, second auxiliary horizontal fence rod)
Next, the mounting means of the first auxiliary horizontal fence rod 7 will be described in detail with reference to FIGS. 1 and 6. FIG.
As better shown in FIG. 6, the first auxiliary horizontal fence rod 7 is fixed horizontally to one of the fixed vertical fence rods 5 and in the direction opposite to the first auxiliary horizontal fence rod 7. It is fitted and attached to the inside of the second auxiliary horizontal fence rod 13 so that it can move forward and backward. This second auxiliary crossbar rod 13, like the first auxiliary crossbar rod 7, consists of a tube with a square cross-section and is slightly larger in size (by its wall thickness).
It should be noted that this second auxiliary horizontal fence rod 13 is fixed and attached to one of the fixed vertical fence rods 5 because the one of the fixed vertical fence rods 5 is actually divided into two vertically. , and the second auxiliary horizontal fence rod 13 are inserted horizontally, and these three parts are joined by welding.

In this way, when the first auxiliary horizontal fence rod 7 is fitted inside the second auxiliary horizontal fence rod 13 so as to be movable forward and backward, the first auxiliary horizontal fence rod 7 is still attached. is conveniently mounted inside the second auxiliary horizontal fence rod 13 so that its forward/backward position can be switched in a plurality of stages (four stages in this embodiment).
For this purpose, the first auxiliary horizontal fence rod 7 is provided with through-holes 14 at three locations in its length direction at appropriate intervals so as to pass through the center of the rod (square pipe). A through hole 15 is similarly provided at a predetermined position in the longitudinal direction of each of the second auxiliary horizontal fence rods 13 .
When one of the three through-holes 14 and the through-hole 15 are aligned, a bolt 16 can be passed through both holes to fix the first auxiliary horizontal fence rod 7 at that position. It is possible.

FIG. 6 shows a case where the central through-hole 14 and the through-hole 15 of the three through-holes 14 are aligned. is fixed and installed in its normal position.
On the other hand, if the through-hole 14 located at the left end in the drawing of the three through-holes 14 and the through-hole 15 are aligned, and the first auxiliary horizontal fence rod 7 is fixed at this position, , the first auxiliary horizontal fence rod 7 is installed at a position closer to the right side than the normal position. Then, the distance between the pivot 8 and the other fixed vertical fence rod 4 is the shortest, and the stanchion 1 has a size suitable for calf cows to eat feed.
Similarly, in order to deal with a dairy cow that is larger than normal, the through hole 14 located on the right end in the drawing of these three through holes 14 and the through hole 15 are aligned with each other, and the through hole 15 is placed at this position. , the first auxiliary horizontal fence rod 7 may be fixed.

Further, FIG. 7 shows a case where the first auxiliary horizontal fence rod 7 is retracted to the maximum depth (the innermost part) inside the second auxiliary horizontal fence rod 13, and this case is shown in FIG. In this case, the through hole 14 for fixing the first auxiliary horizontal fence rod 7 at this position is not provided. However, the distance between the pivot 8 and the other fixed vertical fence rod 4 is maintained at a maximum to allow cows that have fallen asleep in the stanchion 1 to be easily removed from the stanchion 1 as shown in FIG. It is convenient because it can be pulled out.

(locking means)
Next, the locking means for locking the rotating vertical fence rod 6 in the vertically upright position will be described.
As shown in FIG. 1, this locking means is provided at a predetermined interval on the outer surface of a lock operating rod 9, which is positioned immediately above the upper frame pipe 2 and parallel thereto. It is composed of a stop pin 10 and an engagement plate 12 rotatably supported on the upper end of a U-shaped bracket 11 provided on the side of the rotating vertical fence rod 6 .
Here, the U-shaped bracket 11 is integrally fixed to the upper end of the rotating vertical fence rod 6 at a predetermined angle with it, and the U-shaped portion is attached to the upper frame pipe 2 . , and the lock operation rod 9 from below, and are set so as to be able to move relative to them.

Then, the rotating vertical fence rod 6 rotates clockwise in the figure from the position shown in FIG. The engagement plate 12 slides on the outer surface of the lock operation rod 9 and gets over the locking pin 10 in the process of reaching the vertically upright position. Then, the tip of the engaging plate 12 engages the locking pin 10 in the counterclockwise direction. (See FIGS. 2 and 3).
To unlock this lock, the lock operating rod 9 is rotated 90 degrees using the handle 17 (see FIG. 2) provided at the left end thereof to turn the locking pin 10 rightward, or the lock is released. For each stanchion 1 that needs to be untied, the engaging plate 12 is picked up by hand and lifted upward so as to get over the locking pin 10 in the counterclockwise direction (see FIG. 4).

(Another fixed vertical fence rod)
In addition, between the upper frame pipe 2 and the lower frame pipe 3, adjacent to the one fixed vertical fence rod 5 on the left side, at least another fixed vertical fence rod 18 has its upper and lower ends. It is fixed to the frame pipe 2 and the lower frame pipe 3 respectively, and the left end side of the second auxiliary horizontal fence rod 13 is fixed to the other fixed vertical fence rod 18, The support of the auxiliary horizontal fence rod 13 is further strengthened.

Here, the other fixed vertical fence rod 18 may have the same structure as the one fixed vertical fence rod 5, or may be a circular pipe divided vertically into two. Furthermore, the second auxiliary horizontal fence rod 13 may be sandwiched between the front and rear sides, and two elongated strip-shaped flat plates may be fixed to this position at that position. In the stanchion 1 of this embodiment, the last-mentioned two elongated strip-shaped flat plates are employed. These two elongated strip-shaped flat plates may be one if the strength is ensured.
In addition, as described above, the above-mentioned "one having the same structure as one of the fixed vertical fence rods 5" has a rectangular cross section and is divided into two upper and lower parts. It refers to a structure in which the fence rods 13 are inserted horizontally and these three parts can be welded together.

(Auxiliary vertical fence rod)
A relatively short auxiliary vertical fence rod 19 is fixed downward to the tip of the first auxiliary horizontal fence rod 7 . As a result, it is possible to prevent the head and neck of the dairy cow from taking in and out from the space below the first auxiliary horizontal fence rod 7 and the rotating vertical fence rod 6 with a simple structure.

(Action and effect of this embodiment)
Since the stanchion 1 of this embodiment is configured as described above, it is possible to obtain the following functions and effects.
In the cowshed, when it is time to feed the dairy cows in the morning and evening, the feeding area adjacent to the passage of the dairy cows is supplied with the feed by an automatic feeding vehicle, and each stanchion 1 in the interlocking stanchion is operated at that time. As shown in FIG. 1, the movable vertical fence rod 6 is in a state of being turned toward one of the fixed vertical fence rods 5 and laid down.
Then, as shown in FIG. A cow inserts and then lowers its head and neck to eat the supplied feed. At that time, the neck pushes the lower part of the vertical swing rail rod 6, so that the vertical swing rail rail 6 is rotated in a direction (clockwise) to stand up vertically, and the engaging plate 12 is Get over the locking pin 10 . As a result, the engaging plate 12 is already locked by the locking pin 10 in the counterclockwise direction, so that the rotating vertical railing rod 6 is locked in that position as shown in FIG.

In this state, the cow eats feed while its neck is sandwiched in a vertically elongated space formed between the vertically erected rotating vertical fence rod 6 and the other fixed vertical fence rod 4. In the process, the cow sometimes falls asleep in the stanchion 1 as shown in FIG. Alternatively, even if the time (feeding time) in which the dairy cow can eat the feed ends and the cow does not eat the feed, the locking of the rotating vertical fence rod 6 is not released due to human error. , the livestock sometimes falls asleep in the stanchion 1, unable to get out of the same position.

If such a thing occurs, the life of the dairy cow may be threatened and it may cause injury. is lifted (see the curved arrow), the rotating vertical fence rod 6 is rotated counterclockwise to release the engagement with the locking pin 10, and the locking of the rotating vertical fence rod 6 is released. Next, the first auxiliary horizontal fence rod 7 is retreated to the maximum depth (most deep part) inside the second auxiliary horizontal fence rod 13 (see the horizontal arrow below), and is interlocked with this retreating movement. Then, the rotatable vertical fence rod 6 is retracted by the maximum amount toward one of the fixed vertical fence rods 5 (see the upper horizontal arrow) to bring it into the state shown in FIG.

By doing so, the space surrounding the cow's neck is enlarged laterally, the head and neck of the cow are extracted from this space, and the cow is pulled out of this space and freed. becomes easier to do.
In general, when a dairy cow stands up, it first sticks its head forward as much as 1 m, then raises its front legs, then raises its hind legs, and rocks its body back and forth while standing up. The condition shown provides enough space for a cow that has fallen asleep to do so when it tries to wake up.

As a result, compared with the stanchion of the conventional structure, the first auxiliary horizontal fence rod 7 and the rotating vertical fence rod 6 are integrated, and the innermost part and one of the second auxiliary horizontal fence rods 13 are fixed. By a simple and easy work of retreating to the vertical fence rod 5 side, the sleeping dairy cow can be pulled out from the stanchion 1 in a short time and released into a free state. Since only the fitting structure of the horizontal fence rods 7 and 13 is used, the stanchion 1 having a simple structure can be obtained, and the effect is extremely large.

In addition, since a relatively short vertical auxiliary fence rod 19 is fixedly attached downward to the tip of the first auxiliary horizontal fence rod 7, the first auxiliary horizontal fence rod 7 can be moved by a simple structure. Also, it is possible to prevent the head and neck of the dairy cow from being put in and taken out from the space below the rotating vertical fence rod 6 .

Between the upper frame pipe 2 and the lower frame pipe 3, adjacent to one of the fixed vertical fence rods 5, at least another fixed vertical fence rod 18 has its upper and lower ends connected to the upper frame pipe 2. Since the left end side of the second auxiliary horizontal fence rod 13 is fixed to and supported by this other fixed vertical fence rod 18, it can be rotated vertically.
