[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a power type dehorner,
More specifically, the horns of animals can be cut automatically in a short time,
Moreover, it relates to a power type dehorner having good portability.

[0002]

2. Description of the Related Art Cows fattened by fatteners grow large pairs of horns overhead as they grow. By the way, cows fattened in a small barn are likely to accumulate stress and sometimes fight between cows in the barn, but if there are horns overhead, it will hurt each other and cause illness,
The cows with horns grown are dehorned. Conventionally, a large manually operated scissor dehorner has been used for this dehorning operation. This dehorner is one in which an operator with a dehorner applies the blade of the dehorner to the horn of a cow and applies force to a long forked handle to cut the horn.

[0003]

However, since the conventional dehorner is of a scissor type that is manually operated, a large arm force is required to cut a thick and hard corner, and a relatively long time is required for cutting. In addition, the dehorner itself requires a long handle to be cut, which requires a large handle operating force with a hand, which makes the dehorner large and large, which makes it inconvenient to carry. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a power type dehorner that can automatically cut an animal's horn in a short time and has good portability.

[0004]

A method according to the above-mentioned object.
The power type dehorner described is mounted on a portable main body frame, is slidably mounted on a fixed blade having a cutting edge formed in an inner arc shape, and a guide groove formed on the main body frame. The fixed blade is provided with a movable blade having an inner circular arc shape and facing each other in a pair with the fixed blade, and a drive means for the movable blade, and the blade angles of the fixed blade and the movable blade each have a cross section of 9 to 10.5. The angle of the cutting edge of each of the fixed blade and the movable blade is within the range of 40 to 60 degrees in cross section. The phrase "the cutting edge is formed in the shape of an inner arc" means that the cutting edge is formed so that the cutting edge faces toward the center of the arc rather than outside the arc. The drive means
It refers to a driving means using power that can output a force necessary for cutting a corner of a hydraulic cylinder, an air cylinder, an electric cylinder, or the like. The blade is an inclined portion on the blade tip side of the movable blade or the fixed blade, and the tip of this blade is the blade tip.

[0005]

In the power type dehorner according to claim 1, an operator places a fixed blade and a movable blade on the corner of the animal, and actuates the driving means to reciprocate the movable blade to cut the corner. Therefore, the angle of the animal can be cut automatically in a short time without the need for the operator to apply force when dehorning, and the force to cut the angle is reduced as in the conventional scissor-type manual dehorner. Since the long handle required is not needed, the dehorner can be made smaller and lighter, which improves portability. Further, since the movable blade and the fixed blade that face each other are in an inner circular arc shape at the time of cutting, even a hard corner can be smoothly cut without causing slippage. Then, when the drive means is operated during dehorning, the edge of the movable blade having a cross section of 40 to 60 degrees is pierced at the corner to which the fixed blade is applied, and then the blade is directly cut with a blade having a cross section of 9 to 10.5 degrees. Since it is dropped, it cuts into the corner without breaking the edge and cuts the corner sharply without spilling.

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIG. 1 is a plan view of a power type dehorner according to an embodiment of the present invention, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, and FIG. 4 is used for the power dehorner. FIG. 5 is an enlarged cross-sectional view of the movable blade and the fixed blade on the blade tip side, and FIG. 5 is a perspective view showing the same usage state.

As shown in FIGS. 1 to 3, a power type dehorner 10 according to an embodiment of the present invention includes a pair of thick elongate frames 11a and a connecting member 11b for connecting the bases thereof. The main body frame 11 has a portable main body frame 11, and a hydraulic cylinder 12, which is an example of a drive unit that also serves as a handle, is attached to the base portion of the main body frame 11. A connecting plug 13a of a flexible hose 13 is provided at the base of the hydraulic cylinder 12 so as to project from the hydraulic cylinder 12, and the hydraulic cylinder 12 has a hydraulic supply device 14 having a built-in hydraulic pump via the hose 13.
It is connected to. Also, the rod 1 of the hydraulic cylinder 12
A connecting block 15a is fixed to the tip of 5,
A substantially crescent-shaped movable blade 16 that slides along the inner surface of the body frame 11 is bolted to the connection block 15a. Grooves 11c having the same depth are formed on the tip surfaces of the respective long frames 11a, and the bases of the substantially crescent-shaped fixed blades 17 are firmly bolted in the respective grooves 11c while being inserted. There is. As shown in FIG. 4, the surfaces of the movable blade 16 and the fixed blade 17 which are opposed to each other are flat surfaces, and the cutting edges 16 of the movable blade 16 and the fixed blade 17 are flat.
The cross-section angle of a, 17a is 45 degrees, and the blades 16b, 17
The angle of b is 9 to 10.5 degrees. As shown in FIG. 1, the guide grooves 18 of the movable blade 16 are formed on the inner surfaces of the elongated frames 11 a facing each other from the central portion to the tip thereof, and between the movable blade 16 and the fixed blade 17 of the main body frame 11. A space 20 for inserting the horn 19 of the cow is formed. In addition, the other end of the U-shaped handle 21 whose tip projects obliquely upward is bolted to one surface of the tip of the body frame 11 (see also FIGS. 2 and 3). In this way, the other handle 21 is attached to one surface of the tip portion of the main body frame 11,
Since the tip of the other handle 21 is projected obliquely upward in a U shape, for example, when the other handle 21 is projected on the end face in the length direction of the main body frame 11 or is projected on one face of the main body frame 11 in an orthogonal state. In comparison with the above, the other handle 21 can be easily gripped during dehorning and more force can be applied during dehorning work.

Next, in using the power type dehorner 10 according to one embodiment of the present invention, as shown in FIG. 5, a person who assists the dehorning work pulls the tweezers 22 to hold the cow. Attach
An operator inserts the cow's horn 19 into the space 20 of the power type dehorner 10, and while keeping this state, one hand holds the hydraulic cylinder 12
And the other hand grips the other handle 21 to firmly support the power type dehorner 10 from both sides, and then the hydraulic pressure supply device 1
When the hydraulic cylinder 12 is driven by turning on the switch of No. 4, the rod 15 is moved in and out only once, and the guide groove 18
The movable blade 16 is reciprocally moved along the line to cut the corner 19. That is, as shown in FIG. 4, the corner 19 to which the fixed blade 17 is applied is pierced by the blade edge 16a of the movable blade of 45 degrees, and the piercing force also pierces the blade edge 17a of the fixed blade 17 on the opposite side of the corner. As the cutting progresses further, the corner 19 remains the blade 16 with a cross section of 9 to 10.5 degrees.
As it is scraped off by b, 17b, the blade 1
6b and 17b bite without breaking, and the corner 19 can be sharply cut without the blade spilling. Further, since the movable blade 16 and the fixed blade 17 which face each other have an inner arc shape, even a hard corner 19 can be cut smoothly without causing slippage.

As described above, since the corner 19 is cut between the movable blade 16 and the fixed blade 17 which are reciprocally moved by the hydraulic cylinder 12, the cow's corner 19 can be cut without the operator applying force at the time of cutting. Can be automatically cut in a short time of a few seconds, and the dehorner 10 is small and lightweight because it does not require a long handle that is required to reduce the force to cut the corner unlike the conventional scissor-type manual dehorner. And portability is improved. Moreover, in this way, at both ends of the main body frame 11,
Since the hydraulic cylinder 12 which is one handle that can firmly press the power type dehorner 10 with both hands at the time of dehorning and the other handle 21 are disposed, the dehorning work is performed even if the cow is a little rough. Can be done safely and accurately.

The present invention is not limited to this embodiment, and even if there is a design change within the scope of the invention, it is included in the present invention. For example, in the embodiments, the hydraulic cylinder is shown as the driving means, but the driving means is not limited to this, and other driving means capable of outputting a force necessary for cutting a corner of an air cylinder or an electric cylinder may be used. Good. In the above-described embodiment, the handles are provided at both ends of the main body frame (however, one of the handles also serves as the driving means), but the present invention is not limited to this, and only one handle may be provided. This one handle may be provided as a separate body without also serving as the driving means. It should be noted that the main body frame itself may be shaped so that the main body frame itself can be held without providing a handle protruding from the main body frame. Further, in the above embodiment,
Although the switch of the driving means is provided on the side of the hydraulic pressure supply device that is the power source, it is not limited to this and may be provided on the side of the power type dehorner such as the driving means or the main body frame. Furthermore, in the embodiment, the angle of the cutting edge of the movable blade and the fixed blade is set to 45 degrees, but the angle of the cutting edge is not limited to this and may be within the range of 40 to 60 degrees, and at least the movable blade. May be a blade having such dimensions. Further, in the embodiment, the shapes of the movable blade and the fixed blade are substantially crescent-shaped, but the shape of the cutting edge is not limited to this and may be any arc shape such as a semicircle.

[0011]

In the power type dehorner according to the first aspect, the inner arcuate fixed blade attached to the portable main body frame and the guide groove formed in the main body frame are slidable. It is equipped with an inner arcuate movable blade which is attached to the fixed blade and which is paired with the fixed blade, and a driving means for the movable blade. Therefore, the reciprocating movement of the movable blade by the driving means causes the worker to apply a force during cutting. The corners can be cut automatically in a short time without needing a long handle to obtain the large handle operating force required for manual cutting, unlike the conventional scissor-type manual dehorner. The size and weight of the dehorner can be reduced and the portability of the dehorner can be improved. Further, since the movable blade and the fixed blade which face each other are in the shape of an inner arc, it is possible to cut smoothly even at a hard angle without causing slippage. When the drive means is operated at the time of removing the angle, the cross sections 9-10.
The movable blade has a cross section of 40 to 60 degrees, and the cross section of the movable blade has a cross section of 9 to 10.5 degrees. Since it is scraped off by the blade body, both the fixed blade and the movable blade bite into the corner without breaking, and the corner can be sharply cut without the blade spilling.
