Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to the field of livestock industry, and more particularly to an electric hoof shaving device for animals that can easily prepare an overstretched hoof of dairy cows and beef cattle.

[0002]

[Prior Art]

 The limbs of dairy cows and beef cattle, which are large livestock in the field of livestock, constantly support their own weight, and if they extend too much, they will suffer from lack of exercise, their physical shape will become poor, and their stress will increase their appetite. Cause a decline. As a result, reproductive disorders and mastitis are caused, fattening efficiency is reduced, and milk and meat are reduced, which is a serious obstacle to livestock production. Therefore, the management of limbs of dairy and beef cattle has important economic significance 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 processed in a very short time due to the nature of cattle that does not have the habit of raising limbs, and is a work that requires labor and skill. A full-time employee (hereinafter referred to as a hoof cutter) is asked to do this at the beginning of the training period, and then every four months after that. 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 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.

An electric hoofing device has also been proposed, and in Japanese Utility Model Publication No. 39-36970, a method is provided in which a metal disk is provided with a blade having an angle of 15 to 60 degrees to rotate the hoof at a high speed so that the hoof is displaced. JP-A-60-172247 discloses a method in which a rotor is provided with a canna and is pressed against the bottom of a hoof of livestock while performing high-speed rotation to perform hoof cutting. Further, Japanese Patent Publication No. 52-46870 discloses a method in which two opposing rollers are respectively rotated in opposite directions, the blades are oriented in the respective rotation directions, and hoofing is performed.

[0007]

[Problems to be solved by the device]

 However, the shape of a cow's hoof is complicated, and its hardness varies depending on the part of the hoof. Therefore, the technique disclosed in Japanese Utility Model Publication No. 39-36970 and Japanese Patent Publication No. 60-172247 discloses a hoof-cutting surface. It is difficult to control the details and especially the soft parts because the angle of hoofing is fixed, and it is safe for general livestock farmers to injure the legs of cattle and injure users if they are not skilled. There was a problem above, and it was impossible to arrange it well. On the other hand, the method disclosed in Japanese Examined Patent Publication No. 52-46870 is tentatively safe, but it is impossible to cut the details because the hoof is cut only at a limited part of the circumferential surface of the cylinder.

[0008] Therefore, the hoof can be finely trimmed well, rough shaving to adjust the shape of the hoof roughly, and fine polishing of the finish can be handled with a simple structure that can be performed even by a general farmer who is not skilled. There has been a demand for an easy automatic electric hoofing machine.

[0009]

[Means for solving the problem]

 The present invention has an object to solve the above-mentioned problems, and has a structure that has a rotating shaft capable of reversing the rotating direction, is easy to handle, and is easily attached to and detached from the rotating shaft. It is characterized by comprising a conical, cylindrical or frusto-conical hoofing portion provided with a roughened surface or a cutting projection.

The present invention comprises a grip portion and a hoof portion detachably attached to the tip of the grip portion. The grip has a weight that can be operated with one hand, has a small motor built-in, a power cord extends from one end, and has a connecting means at the other end that can securely attach the hoof cutting part. Further, it is preferable to have a power switch, a forward / reverse switch that can reverse the rotation direction, a rotation speed adjustment knob, and a safety switch. The small motor is for 100V single-phase alternating current, and the direction of rotation can be reversed by switching the forward / reverse switch. The rotation speed can be appropriately switched to 800 to 30,000 rpm, preferably 1000 to 20,000 rpm.

The hoof shaving portion is composed of a grinding portion and a connecting shaft extending from the grinding portion, and the connecting shaft is securely connected to the connecting means of the grinding portion to prevent loosening even at high speed rotation. The connecting means may be provided on the gripping part or on the hoof-cutting part as long as it can be surely connected and is easily attached and detached. The shape of the grinding portion is a conical shape, a cylindrical shape, or a truncated cone shape. In any case, the tip is rounded for safety and the tip is a smooth surface. The body is hollow to reduce weight. In the case of a cone or a truncated cone, the angle is not limited, and in the case of a cylinder, the diameter is 5 to 100 mm, preferably 10 to 50 mm.

In the ground part of the hoofing part used at the beginning of hoofing, non-directional hoofing projections are scattered all around the circumference except the tip part. That is, even if the rotation direction is reversed, it can function as a blade in each direction, with protrusions with a height of 1 to 8 mm, preferably 2 to 5 mm scattered every 2 to 8 mm square. is there. Generally, it is used at 3000 to 30000, preferably 5000 to 15000 rpm. The material of the hoof part is made of special steel, lightweight alloy, hard ceramic, etc. If the grinding surface has an inclined shape, even if it is used at the same number of revolutions, the peripheral speed differs depending on the part, and it is possible to use it delicately. In addition, the conical grinding part has an advantage that it can fit into the details of the hoof. At the finishing stage, the hoofing part, which has the sandpaper used for ordinary grinding grinders on the cutting surface, is attached to the gripping part. The rotation speed is 800 to 10000 rpm.

The automatic hoofing machine for animals of the present invention can be equipped with a dust prevention device and an automatic stop device. If a dust prevention device is installed, there is no danger of inhaling dust into the hoof, which will prevent illness from inhaling dust. If a safety device is installed, the safety switch will automatically operate and the motor will stop even if the grip is misplaced and the grip is released.

In hoofing, first, the cow to be hoofed is fixed by a retaining frame, and the part that has been conventionally cut using a hoof sickle, hoof blade or hoof scissors and a mallet is used. By attaching the hoof-cutting part with the hoof-cutting protrusion to the gripping part, the large hoof-cutting protrusion can be attached according to the progress of hoof-cutting. You can work with it.

[0015]

[Action]

 In the present invention, the hoof part and the grip part having a rotation shaft capable of reversing the rotation direction are provided, and by exchanging the hoof part detachably, the same grip part is simply used as an attachment. The shaving process and finishing process can be performed all at once by simply exchanging the hoofing part. Furthermore, even with the same hoof part, it is easier to handle if the direction of rotation is reversed depending on the part of the hoof. In this case, the direction of rotation can be easily reversed, and the rotation speed can be adjusted at any time. Furthermore, when using a conical or frusto-conical grinding part, the circumference varies depending on the part used, so the peripheral speeds differ even at the same number of revolutions, so the grinding force can be adjusted without adjusting the number of revolutions. Fine adjustment is possible.
