Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the field of animal husbandry, and more particularly to an animal hoofing device that allows an unskilled person to easily prepare an overextended hoof of a dairy cow or a beef cow.

[0002]

[Prior Art]

 In the field of livestock industry, the limbs of large livestock dairy cows and beef cattle always support their own weight, and if these limbs are excessively stretched, they will lack exercise and their body shape will become poor, causing stress and appetite. Cause decline. As a result, it causes reproductive disorders and mastitis, lowers fattening efficiency, reduces milk and meat production, and is a serious obstacle to livestock production. Therefore, the management of limbs of dairy and beef cattle has an economically important meaning in the livestock industry.

The hooves of cattle extend about 3 to 10 mm per month, but when the animals are grazing or kept in an open-closed barn, the hooves naturally wear, so only hoofing can be done by shaping. The hoofs of cattle bred in a barn are lengthy and have overlapping hooves, and their limbs are weaker than when the center of gravity is behind the bottom of the hoof. The loss of limb not only makes the appearance of the cow worse, but it also imposes strain on the muscles of the limbs, leading to weight loss and shorter life.

[0004] Hoofing of dairy cows and beef cattle generally needs to be performed by a hoof-catcher because it requires an extremely short time due to the nature of cattle that does not have a habit of raising limbs and requires labor and skill. The training is performed at the beginning of the training period, which is called by a skilled hoof-cutter specialist, and then once every four months. An overstretched hoof cannot be shaped at once, and must be shaped several times. Also, there is a limit to the amount that can be scraped off at one time.

[0005] Conventionally, when hoofing, rough cows are put in a yard, and gentle cows are used with a sickle, hoof sword, hoof scissors, hoof file, etc. I used a hoof knife and a mallet to cut the area around the tongue in good shape, and then sanded the whole piece to finish. How to use hoof sickle, hoof sword, hoof scissors, hoof file, etc., how much of which part of the hoof of a dairy cow or beef should be shaved before the work is done to obtain the correct hoof shape and posture. There is a drawback that it requires a lot of labor, time, and skill because it is necessary to make a hoof-judging decision, and several hoof-housing assistants have to lift one leg of the cow. A general livestock farmer could not easily perform hoof cutting, and had to resort to a hoof cutter.

Japanese Utility Model Publication No. 39-36970 discloses a method in which a metal disk is provided with a blade having an angle of 15 to 60 degrees and is rotated at a high speed to cut a hoof. This method had a simple device and could be hoofed by an unskilled person in a short time.

[0007]

[Problems to be solved by the device]

 However, although the above-mentioned hoof cutting disc has the advantage that it has a simple structure and can be used easily, it has the drawback that the hoof cannot be seen from the front because the hoof is blocked by the disc during hoof cutting. The work efficiency is poor because the hoof-cutting part must be looked into from the side or the hoof-cutting work must be interrupted.

[0008] Therefore, there is a demand for a hoof shaving device for animals that has a simple structure and that can continue hoof shaving while observing the shape of the hoof, and that can be performed even by a person who is not an ordinary skilled livestock farmer. Was there.

[0009]

[Means for solving the problem]

 The present invention is intended to solve the above-mentioned problems, and its configuration is such that a plurality of perforations are provided on the surface of a disc having cutting means, and the perforations can be seen through when the disc is rotated at high speed. In addition to the above, it is characterized in that the disk is attached to the rotary shaft, and further, hoof cutting efficiency is improved by projecting all or part of the peripheral edge of the perforation as a cutting means. Characterize.

Steel is generally suitable as the material of the disk used in the present invention, but tough synthetic resin and ceramics can also be used. The disk has a diameter of 50 to 150 mm and a thickness of 1 to 5 mm. The number of perforations is plural, preferably 3 to 20, and more preferably 4 to 10. As for the location of the perforations, avoid the area where the rotary shaft is attached at the center, and arrange the long and narrow perforations near the center so that the hoofs on the opposite side can be seen evenly on the outer periphery without impairing the strength of the disc. That is, it is preferable that the size and the arrangement are such that the deviation of the center of gravity is as small as possible. The shape of the perforations is long in the centrifugal direction, and the same shape is preferable.

The size of the perforations is not limited, but the object of the present invention cannot be achieved when the size of the perforations is so small that the opposite side is not visible, or when the number of perforations is insufficient. In short, it is preferable that the perforations of the size and number that allow the shape of the hoof on the opposite side to be seen through during rotation are evenly and widely arranged on the circumferential surface.

Examples of the cutting means provided on the disk include a blade, a protruding cutting edge, a file-like rough surface, or a tool having a file-like rough surface. As a blade, it is a blade consisting of protrusions with a hard and sharp tip, whether it is a long blade edge provided in the radial direction, the blade tips consisting of small protrusions are scattered, or an intermediate shape between these. It doesn't matter if there is. If sharp edges are provided on both sides of the protrusion and the cutting edge is used, if the rotating device equipped with a disk can be turned over, it can be rotated in the desired direction according to the hoof part and scraped. It is preferable that the hoofs are evenly arranged on the disc so that the hoof can be shaved without giving a shock.

As the file-like rough surface, parallel striped irregularities are provided on the surface of the disc material, the whole is processed into a rough surface with irregularities, or abrasive grains are applied, and polishing paper, polishing cloth, etc. are used. It may be attached, in short, as long as the disc surface is uniformly roughened. The file-like rough surface does not have to be provided on the entire surface of the disk, but it is preferable that they are evenly arranged so that the disk can be smoothly scraped when rotated at a high speed. Further, it is also possible to make the portion of the projection that serves as the blade edge a file-like rough surface so that it has both the functions of the blade and the file-like rough surface.

In addition, depending on the hoof cutting process, there are cases where it is desired to grind strongly or weakly, but the roughness of the cutting means is changed between the peripheral portion and the central portion of the disc to perform roughing and finishing. It is possible to work more efficiently by changing the position from the center of the disk used together.

Further, if the peripheral edge of the perforation is projected from the disk surface, this projection has a function as a cutting edge. In this case, it may be provided on the entire circumference of the perforation, but it is effective to provide it on the side of the perforation that comes into final contact when the disc rotates. A disk is simply provided with a plurality of perforations, and only one side of the perforations is projected by 0.5 to 1 mm, and the projection is roughened, or a polishing cloth or the like is attached to form a file. There is a method such as using a blade. Alternatively, there is a method in which both sides in the radial direction are projected with respect to the disc of the perforation and the hoof can be excised on both sides of the perforation even if the rotation direction of the disc is reversed.

To rotate the disc, a rotating device similar to the electric disc grinder may be used, or the electric disc grinder itself may be used and the disc of the present invention may be attached instead of the grindstone of the grinder. Alternatively, it is possible to use the grip portion of the electric hoof maker for animals which can reverse the rotation direction disclosed in the specification of Japanese Patent Application No. 3-55238 filed by the present applicant.

[0017]

[Action]

 The present invention was completed in view of the fact that the opposite side can be seen through during rotation by providing a plurality of relatively large perforations in the disk. As a result, since the shape of the hoof can be confirmed during hoof cutting, hoof cutting work can be performed efficiently. Further, both or one side in the radial direction with respect to the disk at the peripheral portion of the plurality of holes is processed so as to slightly project so that it can function as a cutting edge. The cutting edge processed in this way is reasonably sharp and suitable for hoof cutting, so it is safe to handle.

【Example】

 FIG. 1 is a plan view of a disk used in an animal hoofing device of the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a sectional view taken along line III-III of FIG. Reference numeral 1 is a steel disk having a diameter of about 10 cm, and eight perforations 2 having a width of about 5 mm and a length of about 25 mm are provided on the circumference in a radial direction. A smooth and most recessed mounting portion 3 was provided in the center, and the center thereof was used as a mounting hole 4. A raised portion 5 is provided on the outer circumference of the mounting portion 3, the hoof-cutting surface 6 provided with the perforations 2 is projected most, and the peripheral portion 7 is lowered to the lower surface again. When the disk is placed on a horizontal surface, the part that comes into contact with the horizontal surface is the mounting portion 3, and the edge line 8 of the peripheral portion 7 is in a state of floating from the horizontal surface.

In this embodiment, after the perforations were cut out, the end portion of each of the perforations arranged in the radial direction on the clockwise side in the longitudinal direction was warped outward by about 0.5 to 1 mm. The edge line on the warped side was used as the cutting edge 9. The cutting edge having such a shape has a moderate sharpness suitable for hoof cutting and is highly safe. Reference numeral 10 is a strain generated in the base portion of the cutting edge 9 as a result of warping.

The disc 1 is attached to the shaft of the hoofing machine with the hoofing surface 6 facing outward, and in this embodiment, when the shaft is rotated counterclockwise when viewed from the outer surface of the disc, the tip of the raised portion 5 serves as the cutting edge. It worked and was able to excise the hoof smoothly.

FIG. 4 is an explanatory view showing a state in which a hoof of a cow is hoofed using the hoofing implement of the present invention. The hoof surface 6 of the disk 1 was placed outside, and the mounting hole 4 was attached to the shaft rotated by the motor. 11 is the back of the hoof and 12 is the soil removal. Reference numeral 13 is a cover provided for safety when mounting the disk, and 14 is a grip portion of the hoofing device. When the grasping portion 14 is grasped and the switch is turned on, the disc 1 rotates, and since the perforation 2 exists, the state of the hoof during hoof cutting can be observed from the hoof cutting surface 6. The condition of the hoof can be observed by rotating the hoof at about 100 rpm or more, but 1000 to 5000 rpm is preferable for efficient hoof cutting.
