Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pasture fencing mechanism that prevents cattle from coming off the fence and enables good growth of cattle.

(Prior Art) Pastures and other areas are fenced when raising cattle, and the conventional fence mechanism used at this time consists of wooden or plastic poles and wires or wires attached to these poles via insulators. It was made of thin tape woven with wire.

(Problems to be Solved by the Invention) The above-mentioned pasture fence mechanism is intended to prevent livestock raised there, such as cattle, from escaping, but conventional pasture fence mechanisms are not colored. , poles, insulators, and conductive wire or tape.
It was the same color as the fabric, and was achromatic. On top of that,
Because the conductive wires or tapes are thin, cows often cannot distinguish them even when they come close to them, and come into contact with them and receive an electric shock. Furthermore, because the wires were not visible, even if they received an electric shock, they would sometimes escape from the fence.

Giving electric shock to cows in this way
However, it was not good for the growth of cows, and was a problem because it made cows nervous, and pregnant cows in particular could have miscarriages.

These conventional pasture fence mechanisms were not created with the cow's ecology in mind, and ignored the cow's visual acuity and color discrimination ability, so they were not effective in showing the existence of the pasture fence to the cows. However, the electric shock was given to the cows inadvertently, and it was not possible to completely prevent the cows from breaking out of the fence.

(Means for Solving the Problems) The present invention was invented in view of the above-mentioned problems. A plurality of poles whose surfaces are colored in chromatic colors are erected on the ground, and the poles are placed at appropriate locations on the poles. It consists of tape fixing devices whose surfaces are colored in chromatic colors, and a colored tape with a width of 1 cm or more is stretched between the tape fixing devices.

(Function) A plurality of poles are erected at predetermined locations on the ranch, and tape fixtures with tape wrapped in advance are attached to appropriate locations on the poles to surround the ranch.
The cows grazing in this pasture are about 4m in front of the tape.
Since the tape can be identified at this point, it is possible to reliably prevent cows from running away without giving unnecessary electric shocks, and it is possible to expect natural and good growth of cows.

(Example) Next, an example of the present invention will be described based on the drawings. FIG. 1 is an explanatory view showing the usage state of the pasture fence mechanism, and FIG. 2 is an enlarged perspective view of the tape fixing tool.

In this embodiment, the tape 1 has a width of 1.2 cm and a bright red surface, and conductive wires 2, 2 are woven into the surface of the tape 1.

In this example, the width of tape 1 is 1.2 cm.
This was determined based on the fact that cows can distinguish objects of 1.2 cm from a distance of approximately 4 m, and have a visual acuity equivalent to 0.1 of human visual acuity.
Widths of 1.2cm or more can also be adopted.

Also, since cows can distinguish colors like humans, the surface color of the tape 1, pole 3, and tape fixture 4 is bright red. In this case tape 1
The color of the surface of the cows may be bright red or any other chromatic color, but experimental results show that cows have a particularly strong reaction to bright red, so this color is the most preferred.

Regarding the visual acuity and color discrimination ability of cows mentioned above,
This was discovered by the present inventor as a result of research at the Institute of Livestock Management, Faculty of Agriculture, Kagoshima University. According to this study, as shown in Figure 3, both the Holstein breed and the Japanese Black breed show that the positive reaction rate is higher for chromatic breeds. Furthermore, as for visual acuity, as a result of an experiment using a Landolt ring, it was found that the visual acuity of cattle was 0.1, as it was possible to distinguish a ring with an outer diameter of 60 mm and a thickness and cut width of 12 mm at a distance of 4 meters from the visual target.

The tape fixture 4 is entirely made of plastic, and as shown in FIG. 2, it consists of a cylindrical body 43 with one side open and a locking plate 42 of the tape 1 attached to the other side. This locking plate 42 is provided with two slits 41, 41 in the longitudinal direction on both sides,
The tape 1 is fixed to the locking plate 42 by passing through the slits 41, 41.

Further, reinforcing plates 44, 44 are provided at the opening of the cylinder 43.
A pin 4 is provided on the reinforcing plates 44, 44.
9 support slits 45, 45 are formed.

When using the pasture fence mechanism of this embodiment configured in this way, first, a plurality of poles 3, 3, etc. are erected at predetermined locations on the pasture, and the slits 41, 41 are inserted at appropriate locations on the poles 3. The pasture is surrounded by attaching a tape fixture 4 with a tape 1 wrapped around it.

When fixing the tape fixture 4 to the pole 3,
It is sufficient to engage the cylindrical body 43 with the pole 3, but if necessary, the reinforcing plates 44, 4 can be connected with the pin 49.
4 strengthens the stability of the tape fixture 4. Then, a separately arranged power supply device 10 causes a current to flow through the conductive wires 2 woven into the surface of the tape 1.

Cows grazing in a pasture with such a pasture fence system can identify Tape 1 at a point about 4 meters in front of Tape 1 for the reasons mentioned above, so they will not collide with Tape 1 and will be able to avoid mischief. It provides a good breeding environment for the cows as they are not exposed to electric shock. Also, the pole 3 or the tape fixing device 4 is bright red like the tape 1, so
These devices are also effective in preventing cattle from breaking out of fences.

(Effects of the Invention) As described above, in the present invention, an opening is formed on one side of the chromatic-colored pole and cylinder, reinforcing plates are provided on both sides of the opening, and pins are attached to the reinforcing plate. A tape fixing device is constructed in which a support slit is formed and a locking plate is formed on the other side, tape locking slits are provided in the vertical direction on both sides of the locking plate, and the surface is colored in a chromatic color. However, since a colored tape with a width of 1 cm or more with conductive wire woven on the surface is stretched between the tape fixing devices, the tape fixing device is firmly fixed to the pole, and the tape fixing device will remain intact even after many years of use. The tape does not come loose from the pole, so the fixed position of the tape stretched on the pole is maintained, and the distance between the stretched tapes is maintained, preventing the tape from breaking. Since the cows are aware of its presence before they are touched, it is possible to prevent the cows from escaping without having to give them an electric shock, and since the cows are not exposed to electric shocks, they are able to grow freely.
