Technical Field

[0001] The present invention relates to the technical field of livestock breeding and animal health management, and particularly relates to a magnetic suction type automatic falling ear tag cap and a falling method thereof. Background Art

[0002] Existing ear tags are removed by using scissors or pliers. The normal operation of cutting the ear tag is: fixing the ear → inserting the pliers or scissors into the position where the ear tag is to be cut → cutting. It is difficult to accurately locate the position of the ear tag in the swinging state of the ear during the movement of the pig when the pig is alive, and the operation is difficult. Or in the slaughterhouse, it is cut off when the pig is dead. At present, there is a lack of a convenient and simple method to quickly remove the ear tag in the live pig state. Summary of the Invention

[0003] In view of the above analysis, the embodiments of the present invention aim to provide a magnetic suction type automatic falling ear tag cap and a falling method thereof, so as to solve the problems of difficult ear tag removal in the live pig state, easy injury to pigs and causing injury to personnel. And a pure mechanical design scheme is adopted to avoid the cost of the ear tag increasing by more than 10 times due to the use of electronic devices, etc., resulting in inability to be practically popularized.

[0004] On the one hand, the present invention provides a magnetic suction type automatic falling ear tag cap, including an ear stud end piece and an ear stud;

[0005] The ear stud includes an ear stud main body and a clamping block, and the ear stud main body is clamped with the clamping block;

[0006] The ear stud end piece includes a disc-shaped main body and an elastic column, the upper end of the elastic column is connected with the disc-shaped main body, and the lower end of the elastic column is clamped with the clamping block.

[0007] Further, a first protrusion is provided at the lower end of the elastic column.

[0008] Further, a flat surface portion is provided at the edge of the disc-shaped main body, and the upper end of the elastic column is connected with the flat surface portion.

[0009] Further, a first groove is provided on the flat surface portion, and the two first grooves are respectively located on both sides of the elastic column.

[0010] Further, a second groove is provided on the circumferential surface of the clamping block, and a third groove is provided in the second groove, and the third groove is connected with the first protrusion.

[0011] Further, a first through hole is provided in the middle of the clamping block.

[0012] Further, the ear stud end piece further includes a rotation prevention pin, the upper end of the rotation prevention pin is connected with the lower end of the disc-shaped main body, and the lower end of the rotation prevention pin is arranged in the first through hole to limit the clamping block.

[0013] Further, it further includes an ear tag sheath, and the ear tag sheath is connected to the stud body.

[0014] Further, the ear tag sheath includes an adjusting silica gel and a sheath, the adjusting silica gel is arranged in the sheath, and the upper end of the stud body passes through the adjusting silica gel and is connected to the clamping block.

[0015] On the other hand, the present invention provides an automatic detachment method for an ear tag cap, and the ear tag cap is the magnetic adsorption type automatic detachment ear tag cap as described above.

[0016] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects:

[0017] (1) The stud end piece of the present invention is clamped with the clamping block, and the stud body and the clamping block are clamped. When it is necessary to remove the ear tag cap from a pig, the magnet attracts the ear tag and then naturally pulls to make the detachment mechanism detach from the ear tag cap. There is no need to fix the pig's ear to accurately position the ear tag, and there is no need to use pliers to cut deeply. The ear tag cap can be attracted by the magnetic force over a large range, and it is easy to trigger the unlocking mechanism through magnetic adsorption. There is no need for a cutting operation, which can avoid hurting the pig with scissors or pliers and prevent the pig or the operator from being injured due to the stimulation of the pig.

[0018] (2) The present invention is provided with elastic columns at the edge of the disc-shaped main body, and the lower ends of the elastic columns are clamped with the stud. When the stud end piece and the stud need to be detached, the magnetic force attracts the stud end piece, so that the elastic columns are separated from the stud. When the elastic columns are clamped with and separated from the stud, the lower ends of the elastic columns will deform outward under the action of an external force. Since the elastic columns are clamped and connected to the stud, it is easy to achieve connection and separation.

[0019] (3) A first through hole is provided in the middle of the clamping block of the present invention, the diameter of the first through hole is equal to the diameter of the top of the stud body, a clamping portion is provided on the wall surface of the first through hole, and an L-shaped limiting groove is provided at the top of the stud body. The L-shaped limiting groove includes a vertical groove and a horizontal groove. When the stud body and the clamping block are connected, the clamping portion enters from the vertical groove until the bottom of the vertical groove, and then the clamping block is rotated so that the clamping portion enters the horizontal groove, and the stud body and the clamping block are clamped together. The anti-rotation pin is inserted into the vertical groove to limit the relative rotation between the clamping block and the stud body.

[0020] (4) Since the breeding industry has very strict requirements on the cost of ear tags, and the price is in the range of a few cents, although the solutions of using electronic devices to remotely control unlocking wirelessly are effective, the electronic devices and components such as batteries will increase the cost of this kind of ear tag by more than 10 times compared with the existing ear tags. Therefore, from the perspective of low-cost mass production and popular practical use, the present invention focuses on using only mechanical design solutions to realize the function of automatically detaching ear tags, which is more economical and practical.

[0021] In the present invention, the above technical solutions can also be combined with each other to achieve more preferred combination solutions. Other features and advantages of the present invention will be described in the following specification, and some advantages can be made obvious from the specification or understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained from the content specifically pointed out in the specification and the drawings.

[0036] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0037] Embodiment 1

[0038] A specific embodiment of the present invention, as Figure 1 shown, discloses a magnetically - attracted automatic - detachment ear tag cap, which includes an ear stud end member 1 and an ear stud 2. The lower end of the ear stud end member 1 is snap - connected to the top of the ear stud 2.

[0039] Compared with the prior art, for the magnetically - attracted automatic - detachment ear tag cap provided in this embodiment, the ear stud end member 1 and the ear stud 2 are snap - connected. When it is necessary to remove the ear tag cap from a pig, the magnet attracts the ear tag and then naturally pulls it, causing the detachment mechanism to fall off from the ear tag cap. There is no need to fix the pig's ear to accurately position the ear tag, and there is no need to use pliers to cut deeply. The range of attracting the ear tag cap by magnetic force is large, and it is easy to trigger the unlocking mechanism through magnetic attraction. There is no need for cutting operation, avoiding injury to the pig by scissors or pliers and preventing the pig or the operator from being injured due to the stimulation of the pig.

[0040] It should be noted that the ear tag cap of this embodiment is not only applicable to pigs, but also applicable to other livestock that need to be marked, such as cows, sheep, etc.

[0041] Considering the connection between the ear stud end member 1 and the ear stud 2, as Figure 1 and Figure 2 shown, the ear stud end member 1 includes a disc - shaped main body 11 and elastic columns 12. The upper end of the elastic column 12 is connected to the edge of the disc - shaped main body 11, and the lower end of the elastic column 12 is connected to the ear stud 2. There are at least two elastic columns 12. When there are two elastic columns 12, the two elastic columns 12 are symmetrically arranged with respect to the disc - shaped main body 11. When there are multiple elastic columns 12, the multiple elastic columns 12 are uniformly arranged along the edge of the disc - shaped main body 11. Preferably, there are two elastic columns 12, and the disc - shaped main body 11 is disc - shaped.

[0042] Furthermore, as Figure 2 shown, a flat surface portion 111 is provided on the edge of the disc - shaped main body 11, and the upper end of the elastic column 12 is connected to the flat surface portion 111. In other words, a flat surface portion 111 is cut out on the circumferential surface of the disc - shaped disc - shaped main body 11, and one end of the elastic column 12 is connected to the flat surface portion 111.

[0043] In this embodiment, elastic columns 12 are provided at the edge of the disc-shaped main body 11. The lower ends of the elastic columns 12 are snap-connected to the ear studs 2. When the ear stud end piece 1 and the ear studs 2 need to be detached, the ear stud end piece 1 is magnetically attracted. Since the ear stud end piece 1 is attracted, slight movement of the pig can cause the elastic columns 12 to disengage from the ear studs 2. When the elastic columns 12 are snap-connected to and disengaged from the ear studs 2, the lower ends of the elastic columns 12 will deform outward under the action of an external force. Since the elastic columns 12 and the ear studs 2 are snap-connected, connection and separation are easily achieved. It should be noted that outward means the direction away from the center of the disc-shaped main body 11.

[0044] In order to make the elastic columns 12 deform more easily, as Figure 2 shown, on the planar part 111, first grooves 112 are provided on both sides of the elastic columns 12. Preferably, the elastic columns 12 are in the shape of a cuboid. The depth of the first grooves 112 is not less than the thickness of the elastic columns 12. Preferably, the depth of the first grooves 112 is the same as the thickness of the elastic columns 12.

[0045] It should be noted that the elastic columns 12 are elastic components with a certain hardness and strength, and the reliability of the connection between the ear stud end piece 1 and the ear studs 2 needs to be ensured.

[0046] In order to achieve the snap connection between the elastic columns 12 and the ear studs 2, as Figure 3 shown, first protrusions 121 are provided on the inner sides of the lower ends of the elastic columns 12. Preferably, the first protrusions 121 are small spherical parts, and the first protrusions 121 are used for snap connection with the ear studs 2. When the ear stud end piece 1 and the ear studs 2 are connected, the lower ends of the elastic columns 12 deform under the action of an external force. After the first protrusions 121 are snap-connected to the ear studs 2, the elastic columns 12 return to their original state. When the ear stud end piece 1 and the ear studs 2 are detached, the lower ends of the elastic columns 12 deform under the action of an external force, and the first protrusions 121 are detached from the ear studs 2. When the ear stud end piece 1 and the ear studs 2 are completely detached, the elastic columns 12 return to their original state.

[0047] As Figure 1 shown, the ear studs 2 include an ear stud main body 21 and a clamping block 22. The ear stud main body 21 is snap-connected to the clamping block 22, and the ear stud end piece 1 is snap-connected to the clamping block 22.

[0048] Since the ear stud end piece 1 is snap-connected to the clamping block 22 and the ear stud main body 21 is snap-connected to the clamping block 22, when the ear tag cap needs to be removed from the pig, the magnet attracts the ear tag and then naturally pulls to make the detachment mechanism detach from the ear tag cap. There is no need to fix the pig's ear to accurately position the ear tag, and there is no need to use pliers to cut deeply. The range of attracting the ear tag cap by magnetism is large, and it is easy to trigger the unlocking mechanism by magnetic attraction. There is no need for a cutting operation, avoiding injury to the pig by scissors or pliers and preventing injury to the pig or the operator caused by stimulating the pig.

[0049] Specifically, as Figure 4As shown, the clamping block 22 is a disc-shaped structure. Preferably, the clamping block 22 is a circular disc-shaped structure. In order to connect with the stud end piece 1, a second groove 221 is provided along the circumference of the clamping block 22, and the number of the second grooves 221 is the same as that of the elastic columns 12. When the stud end piece 1 and the clamping block 22 are connected, the elastic columns 12 are arranged in the second grooves 221. A third groove 222 is arranged in the second groove 221, and the third groove 222 is connected with the first protrusion 121. Preferably, the third groove 222 is a small part of a sphere.

[0050] Reference Figure 3 and Figure 4 As shown, when the stud end piece 1 and the clamping block 22 are connected, the elastic column 12 is inserted from one side of the second groove 221 and gradually slides to the other end until the first protrusion 121 is clamped with the third groove 222; before the first protrusion 121 is connected with the third groove 222, the first protrusion 121 moves on the wall surface of the second groove 221 provided with the third groove 222, so that the elastic column 12 deforms outward. When the first protrusion 121 is connected with the third groove 222, the elastic column 12 fits with the second groove 221. When the stud end piece 1 and the clamping block 22 are separated (the stud end piece 1 is subjected to an external force), the first protrusion 121 slides out of the third groove 222 and slides along the wall surface of the second groove 221. The first protrusion 121 makes the elastic column 12 deform outward until the stud end piece 1 is separated from the clamping block 22, and the elastic column 12 returns to its original state.

[0051] In this embodiment, the elastic column 12 is used to make the first protrusion 121 and the third groove 222 engage with each other, so that the connection and separation of the stud end piece 1 and the clamping block 22 are easily realized.

[0052] In order to connect with the stud body 21, referring to Figure 4 、 Figure 5 and Figure 6 As shown, a first through hole 223 is provided in the middle of the clamping block 22. The diameter of the first through hole 223 is equal to the diameter of the top of the stud body 21. A clamping portion 224 is provided on the wall surface of the first through hole 223. An L-shaped limiting groove 211 is provided at the top of the stud body 21. The L-shaped limiting groove 211 includes a vertical groove 212 and a horizontal groove 213. The vertical groove 212 is in an eight-shaped form, and the opening of the vertical groove 212 increases outward from the axis of the top of the stud body 21. The top surface of the horizontal groove 213 is an inclined surface, that is, the opening of the horizontal groove 213 decreases from the vertical groove 212 in the direction away from the vertical groove 212. Correspondingly, the shape of the clamping portion 224 is adapted to the L-shaped limiting groove 211, that is, the clamping portion 224 has the eight-shaped structure of the vertical groove 212 and the inclined top surface.

[0053] Referring to Figure 4 、 Figure 5 and Figure 6As shown, when the stud body 21 and the clamping block 22 are connected, the clamping portion 224 enters from the vertical groove 212 until the bottom of the vertical groove 212, and then the clamping block 22 is rotated so that the clamping portion 224 enters the horizontal groove 213, connecting the stud body 21 and the clamping block 22 together.

[0054] To avoid relative rotation between the stud body 21 and the clamping block 22, in combination with Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the stud end piece 1 further includes an anti-rotation pin 13. One end of the anti-rotation pin 13 is connected to the lower end of the disc-shaped main body 11, and the other end of the anti-rotation pin 13 is used to insert into the vertical groove 212 to limit the clamping portion 224.

[0055] In this embodiment, an anti-rotation pin 13 is provided at the bottom of the disc-shaped main body 11. When the stud end piece 1 and the stud body 21 of the clamping stud are connected, the anti-rotation pin 13 is inserted into the vertical groove 212 to limit the relative rotation between the clamping block 22 and the stud body 21. When the stud end piece 1 is separated from the stud body 21, the anti-rotation pin 13 no longer restricts the clamping block 22. Since the clamping block 22 and the stud body 21 are in a bevel fit, under a little external force, the clamping block 22 will retract to the vertical groove 212 and then disconnect from the stud body 21.

[0056] As Figure 1 shown, the ear tag cap further includes an ear tag sheath 3. The ear tag sheath 3 includes an adjusting silica gel 31 and a sheath 32. The sheath 32 is sleeved on the stud body 21, and the adjusting silica gel 31 is sleeved on the stud body 21 and is located within the space of the sheath 32.

[0057] Specifically, as Figure 1 and Figure 7 shown, a second through hole 311 is provided in the middle of the adjusting silica gel 31, and the diameter of the second through hole 311 is the same as the top diameter of the stud body 21. Fourth grooves 312 are evenly provided on the circumferential surface of the adjusting silica gel 31, and second protrusions 313 are formed between adjacent fourth grooves 312. The adjusting silica gel 31 plays a soft support role. When the stud is subjected to a large inward pulling force, the adjusting silica gel 31 can be compressed and plays a supporting role when there is no external force. The sheath 32 includes a frustum-shaped shell 321 and side ribs 322. The side ribs 322 are provided at the bottom edge of the frustum-shaped shell 321. The adjusting silica gel 31, the top of the stud body 21, the clamping block 22, and the lower part of the stud end piece 1 are arranged in the inner cavity of the frustum-shaped shell 321, and the disc-shaped main body 11 is arranged at the opening of the frustum-shaped shell 321.

[0058] It should be noted that due to the very strict requirements of the breeding industry for the cost of ear tags, with the price in the range of a few cents, although the solutions such as using electronic devices to remotely control unlocking wirelessly are effective, the electronic devices and components such as batteries will cause the cost of such ear tags to increase by more than 10 times compared with the existing ear tags. Therefore, from the perspective of low-cost mass production and popular practical use, the present invention focuses on using only mechanical design solutions to achieve the function of automatically detachable ear tags.

[0059] Embodiment 2

[0060] Another specific embodiment of the present invention is as Figure 8 and Figure 9 shown, which discloses a magnetic adsorption type automatically detachable ear tag cap. The difference from Embodiment 1 is that the stud end member 1 is a shape memory metal that can deform. Before the stud end member 1 deforms, it is in an L shape. One end of the L shape is inserted into the vertical groove 212 to limit the positioning portion 224, and the other end is connected to the connection hole 225 provided on the positioning block 22. When the stud end member 1 deforms, it becomes a straight column and no longer restricts the positioning portion 224. Understandably, the connection hole 225 is higher than the horizontal groove 213.

[0061] In this embodiment, the stud end member 1 is a shape memory metal that can deform. Before deformation, the stud end member 1 is in an L shape. At this time, one end of the stud end member 1 is inserted into the vertical groove 212 to limit the positioning portion 224, and the other end is inserted into the connection hole 225 of the positioning block 22; after the stud end member 1 deforms, it forms a straight column and no longer restricts the positioning portion 224, enabling the rapid detachment of the positioning block 22 and the stud main body 21, and the structure is simpler.

[0062] Embodiment 3

[0063] Another specific embodiment of the present invention discloses a method for detaching an ear tag cap. The ear tag cap is the magnetic adsorption type automatically detachable ear tag cap of Embodiment 1, and the steps include:

[0064] Step 1: Bring a strong magnet close to the stud end member 1 through an external device or manually.

[0065] Step 2: The stud end member 1 is attracted by the strong magnet and detaches from the stud 2.

[0066] Due to the action of the strong magnet, the stud end member 1 is attracted. At this time, move the strong magnet in the opposite direction of the stud, and the stud 2 and the ear tag sheath 3 still remain on the ear.

[0067] Specifically, the lower end of the elastic column 12 deforms, the first protrusion 121 inside the elastic column 12 disengages from the third groove 222 inside the positioning block 22, the stud end member 1 can move with the external force, and the anti-rotation pin 13 moves synchronously with the stud end member 1.

[0068] Step 3: The stud main body 21 and the positioning block 22 are detached.

[0069] After the stud end piece 1 is detached, the stud 2 is in a free state. The stud body 21 and the clamping block 22 are not limited by the anti-rotation pin 13 and can move relative to each other. When the clamping block 22 is subjected to the external force of ear shaking, the clamping block 22 can automatically break away from the limit constraint of the stud body 21.

[0070] Specifically, the anti-rotation pin 13 moves out of the stud 2, and the clamping block 22 loses the limit constraint and can move freely. There is a misaligned chamfer (i.e., inclined surface) between the internal clamping portion 224 of the clamping block 22 and the internal transverse groove 213 of the stud body 21. When subjected to an external force, it can move easily along the chamfer direction, and finally the clamping block 22 will completely break away from the stud body 21.

[0071] Step 4: After the stud body 21 loses the limit, the ear tag sheath 3 can be freely detached.

[0072] Specifically, after the stud body 21 loses the limit of the clamping block 22, the ear tag sheath 3 directly detaches from the stud body 21 under the action of the external force of ear shaking.

[0073] Embodiment 4

[0074] A specific embodiment of the present invention discloses an automatic detachment method for an ear tag cap. The ear tag cap is the magnetic adsorption type automatic detachment ear tag cap of Embodiment 2. The steps include:

[0075] Step 1: Place the stud end piece 1 in an environment with a temperature above 40°C through an external device or manually.

[0076] The stud end piece 1 is a memory metal, and its shape can change at a temperature above 40°C. When the stud end piece 1 is at a temperature above 40°C, its shape automatically changes from bent to vertical.

[0077] Step 2: After the stud end piece 1 deforms, the stud 2 is in a free state.

[0078] After the stud end piece 1 deforms, the stud 2 is in a free state. The stud body 21 and the clamping block 22 are not limited by the stud end piece 1 and can move relative to each other. When the clamping block 22 is subjected to the external force of ear shaking, the clamping block 22 can automatically break away from the limit constraint of the stud body 21.

[0079] Specifically, the stud end piece 1 moves out of the vertical groove 212 of the stud 2, and the clamping block 22 loses the limit constraint and can be freely constrained. There is a misaligned chamfer (i.e., inclined surface) between the internal clamping portion 224 of the clamping block 22 and the internal transverse groove 213 of the stud body 21. When subjected to an external force, it can move easily along the chamfer direction, and finally the clamping block 22 will completely break away from the stud body 21.

[0080] Step 3: After the stud body 21 loses the limit, the ear tag sheath 3 can be freely detached.

[0081] Specifically, after the stud main body 21 loses the limitation of the clamping block 22, the ear tag sheath 3 directly detaches from the stud main body 21 under the action of the external force of ear shaking.

[0082] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.

[0083] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
