DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a stall exit gate structure in a barn.

[0002]

2. Description of the Related Art A stall is a section for housing livestock such as cows one by one, and a cowshed houses one cow at a time for milking. In general, a stall consists of left and right fences and front and rear entrances, and cows are put in from the entrance, milk is squeezed with the front and back closed, and cows are put out from the exit when finished.

For example, in Japanese Unexamined Patent Application Publication No. Hei 6-133661, "opening and closing mechanism of an exit gate in a stall", as shown in FIG. 2 of the publication, stalls 4, 4, work space 3, and stall 4 are arranged from the left. The work space 3 is a work area for humans, and three stalls 4, 4, and 4 other than the work space 3 have bar-shaped gates 10, 1 respectively.
The entrance is closed by leveling the gate 10 and opened by standing. Reference numerals 16, 16, and 16 denote handles for this, and they make an angle of approximately 90 ° with the gate 10. On the other hand, FIG. 3 of the publication is a view of the exits, and each entrance is provided with a double door 9a, 9b. According to the detailed description, the doors 9a and 9b in FIG. 3 are opened and closed via a rope 25 connected to the handle 16 in FIG.

FIG. 7 is a plan view of a conventional stall. A cow 102 is put into a stall 101 as shown by an arrow, and after milking, the doors 103 and 103 are opened to guide the cow to an exit passage 104 as shown by an arrow.

[0005]

The width W of the outlet passage 104 is described below.
Is the sum of the width Wg of the double door 103 and the minimum required width Wr of the passage. The required width Wr is an appropriate value with a margin for the cow width. Originally, the width W of the passage 104 should be the same as Wr, but as described above, the width must be increased by Wg, and the barn must be increased by that amount, which increases the construction cost.

The opening direction of the double door 103 coincides with the traveling direction of the cow. For this reason, if the cow touches the double door 103 due to excitement or the like, the cow may easily open, and it is structurally difficult to have durability enough to withstand the body hit. SUMMARY OF THE INVENTION It is an object of the present invention to provide an exit gate structure capable of reducing the width of an outlet passage and easily enhancing durability in preparation for contact with the body.

[0007]

In order to achieve the above object, a first aspect of the present invention is to attach at least two horizontal rods for closing the stall outlet to the left and right outgoing columns of the stall so as to be able to swing up and down and at least vertically. A stall exit gate structure that can be switched from an open state to a closed state by attaching a vertical rod to the tip of these horizontal rods via a pin and pulling up the vertical rod with an operation lever via a string-shaped member. .

Since the horizontal and vertical rods closing the stall outlet only move up and down, the exit passage is not narrowed by the gate, and the entire width of the exit passage can be used effectively. Also, since the moving direction of the horizontal and vertical rods is up and down,
This direction is different from the moving direction of the cow. As a result, even if the cow hits the body, no rotational force acts on the horizontal and vertical rod pins, and external forces act on the pins in the axial direction and at right angles to the pins. Durability can be easily increased.

According to a second aspect of the present invention, the exit support is a channel so that the horizontal and vertical rods can be stored in the output support when the gate is open. When the gate is open, there are no obstructions, so there is no need to worry about damaging the cow.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings should be viewed in the direction of reference numerals. FIG. 1 is a front view (close gate) of an exit gate of a stall according to the present invention.
Pins 12 are attached to the left and right outgoing struts 11 of the stall.
(... denotes a plurality. The same applies to the following.), Upper and lower two horizontal rods 13 are attached so as to be able to swing up and down, and pins 14. Through the vertical rods 15, 15
, A guide rod 16 is attached to the lower part of the vertical rod 15, a lower end of the guide rod 16 is fitted in a guide groove 17 of the column 11, and a wire 18 as a string-like member is connected to the upper end of the vertical rod 15. Then, the wire 18 is hung on a pulley 21...
A long rod 23 is attached to the other end of the wire 18, and the long rod 23 is pushed and pulled by an operation lever 25. The operation lever 25 is swingably attached to the column 11 via an eye plate 26.

FIG. 2 is a sectional view taken along the line 2-2 in FIG. 1. The outgoing support 11 is a channel, and the vertical rod 15 is a small channel or a half-split pipe. The pins 12 and 14 may be either through pins or stepped pins, and may have any shape as long as they have a hinge function.

By the way, a cow sometimes hits the gate as shown by a white arrow. In order to prepare for this contact, the lateral rod 13 may be appropriately thickened, and the pin 12 may have a large diameter. Conventionally, the opening direction of the door and the direction of contact with the cow were the same, so even if the diameter of the hinge pin was increased,
It didn't work. In this regard, since the opening and closing direction of the gate of the present invention is perpendicular to the moving direction of the cow, the rigidity can be sufficiently increased only by making the pin 12 thicker.

FIG. 3 is a front view (open gate) of the exit gate of the stall according to the present invention, wherein the horizontal rods 13,..., The vertical rods 15, 15, and the guide rods 16, 16 are all supported by the column 1.
1 and 11 are included. Cow 27 in this state
Moves to the drawing table and reaches an unillustrated outlet passage. As shown in the figure, since the horizontal rods 13,..., The vertical rods 15, 15, and the guide and stopper rods 16, 16 do not project from the support 11, there is no fear that the cow 27 touches the projections and is damaged.

FIG. 4 is a sectional view taken along line 4-4 of FIG. For this purpose, a notch 28 is partially provided in the vertical rod 15.

The operation of the above-mentioned stall exit gate will now be described. For convenience of explanation, only the left half of the exit gate structure will be described. 5 (a) to 5 (d) are views for explaining the operation of the stall exit gate of the present invention.
(A) shows an open gate state similar to FIG. To close the gate in preparation for the next cow, enter the control lever 25
Down as shown by the arrow. Then, the long rod 23 starts to fall, and the wire 18 is tensioned. (B) is a view showing a state in the middle, and the vertical rod 15 is moved by the pulling operation of the wire 18.
Rises obliquely to the upper right in FIG.

FIG. 3C shows a closed gate state similar to FIG. Since the operation lever 25 has a self-locking structure, the vertical rod 15 can be held in the state shown in the figure. Although the maximum height of the vertical rod 15 can be determined by adjusting the length of the wire 18, the maximum height of the vertical rod 15 can also be determined by the stopper action of applying the guide rod 16 to the end of the guide groove 17. But don't worry about going up. When opening the gate, the operation lever 25 may be pushed up to proceed in the order of (c) → (b) → (a). Therefore, the gate is closed by depressing the operation lever 25,
The gate can be freely opened by raising the operation lever 25.

By the way, in a barn, there are dusts and straw debris floating, which may enter around the pins 12 and 14 and cause oil shortage or galling.
The swing of 3, 13 becomes bad. On the other hand, when cows are put into the stall and milking one by one, if the gate is not closed, the cows come out and milking cannot be performed. Therefore,
When the condition of the gate is not good, it is better for the gate to close and be selfish. At least milking can be done.

Therefore, in the present invention, the gate is easily closed,
The structure is difficult to open. In (d), when the condition of the gate is not good, the operation lever 25 is raised as shown by the arrow in order to open the gate in the closed state, but only the wire 18 is slackened, and the vertical rod 15 and the horizontal rods 13
Will be locked down. On the other hand, in (a), even if the specificity of the gate is bad, the operating lever 25 is depressed more than usual to forcibly (b) → (c).
The gate can be closed as described above. As described above, the forcible operation is applied to the operation from the opening to the closing.
In the present invention, the milking operation can be performed by performing the forced operation for a while until the repair.

FIGS. 6A and 6B are comparison diagrams of the exit gate structure. (A) is an embodiment of the present invention, in which a support 11 is used.
Is H1. This height corresponds to the height of the gate structure. (B) is a comparative example for the present invention, in which
11 has a structure in which it stands up from the horizontal. Since the height h1 of the support 112 in this comparative example must be added by the length of the horizontal rod 111, h1> H1.
The gate structure is higher than in the embodiment, and the gate structure is correspondingly larger. As described above, the gate structure of the present invention can suppress the height of the equipment and reduce the equipment cost.

It is to be noted that at least two horizontal rods 13 are required to form a parallel link, but the number may be three or more. The channel described in claim 2 does not indicate a channel (groove type) in a narrow sense, but may be any material having a groove for storing U and U.

Furthermore, the stall exit gate structure of the present invention is suitable for dairy cows, but for other uses, for example, large livestock such as horses and pigs are put into the stall one by one and injected with a vaccination or identification. It can also be used when stamping for the purpose. Thus, the application is available for livestock in general and for certain wildlife management facilities.

[0022]

According to the present invention, the following effects are exhibited by the above configuration. Claim 1 attaches at least two horizontal rods for closing the stall outlet to the left and right outgoing struts of the stall so as to be able to swing up and down and at least two vertical rods. This is a stall exit gate structure that can switch from an open state to a closed state by pulling up a vertical rod with an operation lever via a string-shaped member.

The horizontal and vertical rods that close the stall outlet only move up and down, so that the entire width of the exit passage can be used effectively. As a result, even if the cow touches the body, no rotational force acts on the horizontal and vertical rod pins, and external force acts on the pins in the axial direction and at right angles to the pins. Can easily be enhanced.

According to a second aspect of the present invention, the exit support is a channel so that the horizontal and vertical rods can be stored in the output support when the gate is open. When the gate is open, there are no obstructions, so there is no need to worry about damaging the cow.
