Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a livestock feeding device that feeds livestock by rotating a stanchion using the movement of the livestock.

(Prior Art) As shown in FIG. 4, this type of livestock feeding device is designed to connect several pipes 3 arranged at equal intervals on a shelf 2 erected adjacent to a feeding place 1. The lower end of the pipe 3a is pinned so that it can rotate freely.
There is a structure in which the upper end of these pipes 3a is connected to an operating rod 4 extending in the transverse direction.

In this livestock feeding device, the pipe 3a is placed in a position where the pipe 3a is maintained as shown by the solid line in FIG.
and the triangular space 5 formed between the pipe 3a and the pipe 3a.
The operator pushes out the actuating rod 4 at each of the racks 2 while observing that the head of the livestock in the shelf 2 passes through.
Rotate pipe 3a around the pin, and
3a is positioned parallel to the fixed pipe 3 as shown by the two-dot chain line in Fig. 4, so that the livestock in the shelf 2 can be arranged at equal intervals in the feeding area 1, and each livestock can I try to eat enough food.

(Problem to be solved by the invention) In the livestock feeding device of the above type, livestock that moves freely within the shelf 2 can use the triangular space 5 provided in the shelf 2 to
It is necessary for the operator to push out the operating rod 4 and rotate the pipe 3a around the pin after seeing that the livestock head will pass through. There is no problem if you pass
Because livestock move of their own free will, it takes a considerable amount of time for the livestock's head to pass through all the triangular spaces 5, and if this time is long, the livestock that has passed its head through the triangular spaces 5 will also have to pass through the triangular spaces 5. The head may be pulled back from the space 5, and if the operator pushes out the operating rod 4 at the wrong time, the livestock may be injured.

This invention was made in view of the above points,
When the animal's head passes through the triangular space provided in the shelf and pushes down on the stanchion, the stanchion automatically engages the locking device and the animal that has passed its head through the triangular space can pull its head out of the triangular space. To provide a livestock feeding device which feeds a predetermined amount of feed to livestock without causing the livestock to be pulled back.

(Means for Solving the Problems) The livestock feeding device of the present invention has a pair of columns fixed to a lower girder and an upper girder provided in a livestock shed with an interval equal to or larger than the width of the livestock; A cross beam is fixed to one fixed post, and the free end side of the cross beam is fixed to the other fixed post, and the cross beam extends in the horizontal direction so as to leave a gap large enough for the livestock's neck to pass through, and the free end side of this cross beam has an intermediate section. The stanchion is rotatably pivoted and is tilted between the pair of pillars so as to open upwardly, and a locking device keeps the stanchion in a position parallel to the pillars.

(Function) In the livestock feeding device of the present invention, in order to eat food, the livestock voluntarily passes its head through the triangular space formed between the column and the inclined stanchion. When the animal lowers its head, the stanchion pivots about the pivot point of the crossbeam, and the stanchion automatically engages the locking device, keeping the stanchion parallel to the column and forming a triangular space. Livestock that have passed their heads through the triangular spaces cannot pull their heads back, and as a result, livestock that have passed their heads through each triangular space are fed a predetermined amount of food.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a pillar of a livestock shed that houses the inside, for example, and these pillars 10, 10 are arranged adjacent to a feeding place that stores feed such as fodder provided in the livestock barn. The lower girder 11 and upper girder 12 are fixed. In addition, the pillars 10 and 1
Column 13 for forming a shelf placed between 0,
13a has a lower end portion and an upper end portion fixed to the lower spar 11 and the upper spar 12, respectively. The column 13 is longer than the column 13a,
The upper end of the column 13 extends upward from the upper beam 12, and one end of a locking rod 14 is pivotally attached to the protrusion of the column 13. The other end of this locking rod 14 is connected to the column 10 at a position above the upper girder 12 of the column 10.
It is connected via a string 16 to an actuating rod 15 that bridges between the two.

On the other hand, an auxiliary column 13b having the same structure is attached to the column 13a, and one end of a crossbeam 17 is fixed at an intermediate position in the vertical direction between the column 13a and the auxiliary column 13b. The other end, ie, the free end, of the cross beam 17 extends so as to leave a space between it and the side surface of the fixed column 13, which is large enough for the neck of a livestock animal to pass through. A stanchion 18 is rotatably mounted on the free end side of the cross beam 17.

The stanchion 18 is pivotally connected to the crossbeam 17 at a portion below the center of gravity, and in a free state is arranged at an angle between the pair of columns 13 and 13b so as to form a triangle with a wide upper part. . The upper dimension of this triangular space 19 is set to a length that the head of the livestock can freely pass through.

On the other hand, a locking shaft 2 is attached to the upper part of the stanchion 18.
0 protrudes in the lateral direction, and this locking shaft 20
is an engagement recess 21 provided on the lower surface of the locking rod 14.
When engaged, the stanchion 18 is positioned so as to remain parallel to the fixed column 13.
When the actuating rod 15 is turned with a handle, the string 16 is wound around the actuating rod 15, which causes the locking rod 14 to rotate upward, and the locking rod 14 connects to the locking shaft 20.
will be separated from.

Next, the effect will be explained.

Before storing feed such as fodder in the feed storage area provided in the livestock house, the stanchion 18 is placed in the first place.
As shown in the figure, the crossbeam 1 is located below the center of gravity.
7, so the pair of columns 13, 13
They are arranged at an angle so that they form a triangle with a wide upper part. The upper dimension of this triangular space 19 is set to a length that the head of the livestock can freely pass through.

In this state, when fodder or other feed is placed in the feeder, the livestock in the livestock pen try to eat the fodder or other fodder by passing their heads through the triangular space 19 formed between the column 13 and the stanchion 18. , lower its head so that its mouth is closer to the feed such as fodder in the feeding area. When the livestock lowers its head, the stanchion 18 is pushed by the livestock's neck and rotates, and as shown in FIG.
The stanchion 18 is engaged with the engagement recess 21 provided on the lower surface of the locking rod 14, and is positioned so as to maintain the stanchion 18 parallel to the fixed column 13 as shown in FIG. In this state, the livestock has its head exposed and can eat food within a certain range. Once the livestock has eaten food within a certain range, the head will not come off, so the animal will keep its head exposed.

After a predetermined period of time has elapsed, the operator checks the state of the livestock's feed and, if he or she determines that the livestock has eaten enough, turns the handle to turn the actuating rod 15. The leash 16 is wound up, which causes the locking rod 14 to rotate upward, and the locking rod 14 separates from the locking shaft 20. Since the stanchion 18 is pivotally attached to the crossbeam 17 at a portion below the center of gravity, it is arranged at an angle between the pair of columns 13 and 13b so as to form a triangle with a wide upper part. The livestock will have to remove their heads from the area and return to the fence.

(Effects of the invention) As described above, according to the invention, the movement of the livestock is used to operate the stanchion to feed the livestock, making it possible to raise multiple animals at a low cost and manage them. This has the effect that it can be easily carried out.
