Description

Technical Field

[0001] This invention relates to the field of ear tag technology for livestock farming, and more specifically to a marking device for identifying meat sheep. Background Technology

[0002] Ear tags are animal identification devices applied to the ears of livestock to identify their identity and record individual information. Their structure consists of a main tag (including the tag face, neck, and head) and a secondary tag. The main tag penetrates the ear and is fixed in place, while the tag face carries coded information. They are used on large and medium-sized livestock such as cattle, sheep, and pigs.

[0003] Based on their technical characteristics, ear tags are divided into two categories: QR code ear tags and electronic ear tags. The former uses laser engraving to create a QR code system that is resistant to counterfeiting and can be traced. The latter is based on RFID technology with a built-in chip, which supports contactless reading and can be connected to an automated management system to track animals from breeding to consumption. Electronic ear tags record data such as breed and immunization through a unique code, enabling disease traceability and food safety supervision.

[0004] Ear tags are typically installed by drilling a hole in the animal's ear and then applying anti-inflammatory powder to the wound. However, because the ear tag neck penetrates the wound, the anti-inflammatory powder is difficult to get into the wound or only a small amount of powder enters the wound, leading to bacterial growth in the ear's soft tissue and causing ulceration and infection.

[0005] To address this issue, patent number CN109220867B discloses an electronic ear tag for animal husbandry, which includes a male tag, an ear tag neck fixed to one surface of the male tag; a sleeve fitted around the side of the ear tag neck; a female tag snapped onto one end of the ear tag neck; the ear tag neck includes a connecting tube; medicine storage cylinders are fixed to both ends of the connecting tube; each of the two medicine storage cylinders has a first through hole on one opposite side array; an annular cavity is formed on the inner surface of the female tag; four second through holes are formed on the side of the female tag; the second through holes penetrate the female tag and communicate with the annular cavity.

[0006] By fixing medicine storage cylinders at both ends of the connecting pipe, and sleeves fitted around the periphery of the medicine storage cylinders, when the livestock walks and shakes its head, the anti-inflammatory powder in the two medicine storage cylinders is sprinkled into the penetrating wound sequentially through the first penetrating hole and the through hole. This avoids the anti-inflammatory powder being consumed too quickly due to external spillage, and prevents symptoms such as wound ulceration and infection in livestock, thus accelerating the healing time of penetrating wounds. However, when the ear tag neck passes through the ear tear, the wound will adhere to the surface of the ear tag neck, and at the same time, the blood from the wound will flow back into the interior of the first penetrating hole through the through hole, thereby wetting and solidifying the medicine powder. Furthermore, when the blood itself solidifies, it will also block the through hole, preventing the medicine powder from being sprinkled onto the wound.

[0007] In addition, because the wound is attached to the ear tag neck, a scab will form between the wound and the ear tag neck when the wound heals, or even grow directly onto the ear tag neck, making it impossible for the inside of the wound to come into contact with air and breathe, which can easily cause the wound to heal slowly. Summary of the Invention

[0008] In view of the above situation and to overcome the defects of the prior art, the present invention provides a marking device for identifying meat sheep farming.

[0009] The technical solution adopted by the present invention is as follows: a marking device for identifying meat sheep, including a male ear tag head and a female ear tag head.

When the ear tag head ring is threaded on the outside of the ear-piercing tube, the two can be locked together by the anti-detachment structure.

[0013] Preferably, the bottom of the ear tag head ring is equipped with a drug supply structure that can communicate with the upper cotton column. When the ear tag head ring is threaded on the outside of the ear tube and the anti-dislodgement structure is locked, the drug supply structure can pass through the anti-dislodgement structure and communicate with the upper cotton column.

[0014] Preferably, the anti-dislodgement structure includes a conical platform coaxially fixedly installed at the bottom of the ear-piercing tube post, and an anti-dislodgement column coaxially fixedly installed at the bottom of the ear tag head ring. The top surface of the anti-dislodgement column has a conical groove adapted to the conical platform. The outer conical surface of the conical platform has an annular anti-dislodgement groove. The conical surface of the conical groove has multiple anti-dislodgement sliding grooves. Each anti-dislodgement sliding groove has an anti-dislodgement wedge block with a sloping top that is radially slidably installed in it. A wedge spring connected to the anti-dislodgement wedge block is installed inside the anti-dislodgement sliding groove.

[0015] Preferably, the drug supply structure includes a drug supply cylinder fixedly installed at the bottom of the ear tag head ring. The top surface of the drug supply cylinder has a cylindrical recessed part in the middle. The anti-dislodgement column is located inside the recessed part. A drug supply tube is coaxially fixedly installed in the middle of the bottom surface of the recessed part. The top end of the drug supply tube passes through the anti-dislodgement column upward and is placed inside the ear tag head ring.

[0016] Several drug supply holes are penetrated between the inner and outer walls of the top of the drug supply tube. A drug supply cotton strip is installed inside the drug supply tube, and the top of the drug supply cotton strip extends into several drug supply holes.

[0046] The following will refer to the appendix. Figures 1-14 The description provides a detailed description of various embodiments of the present invention.

[0047] Example 1: A marking device for identifying meat sheep farming, as shown in the attached document. Figures 1-14As shown, the device includes a male ear tag 1 and a female ear tag 2. Before use, they are separate units, and are assembled together only during use. The male ear tag 1 includes an ear tag ring 11 and an ear-piercing post 12. An existing electronic identification device can be installed inside the ear tag ring 11. The ear tag ring 11 has a through hole in the middle. The ear-piercing post 12 has an open top and a closed bottom, and is coaxially fixed to the bottom of the ear tag ring 11. The opening at the top of the ear-piercing post 12 has the same diameter as the through hole in the middle of the ear tag ring 11 and they are interconnected. Multiple circumferentially distributed cotton-filled grooves 13 penetrate between the inner and outer walls of the ear-piercing post 12. Inside the ear tag 12, there is a cotton swab 14. The cotton swab 14 extends into multiple cotton swab grooves 13. The outer circumferential surface of the bottom end of the ear piercing tube 12 is provided with an external thread 15. The outer side of the ear piercing tube 12 is detachably installed with a puncture outer tube 16 with a pointed bottom through the external thread 15. When in use, the ear tag male head 1 can be installed on the ear tag pliers, and then the ear of the sheep can be pierced through the puncture outer tube 16. After puncture, the puncture outer tube 16 can be unscrewed and discarded. When the wound is in contact with the outer wall of the ear piercing tube 12, the cotton swab 14 in the cotton swab groove 13 can also be in contact with the wound. The anti-inflammatory solution in the cotton swab 14 can promote wound healing when it comes into contact with the wound.

[0048] The ear tag female head 2 includes an ear tag female head ring 21. The inner side of the ear tag female head ring 21 is provided with an internal thread 22 that can be threaded with the external thread 15. After removing the puncture outer cylinder 16, the ear tag female head ring 21 can be screwed onto the outside of the external thread 15, thereby fixing the ear tag male head 1 and the ear tag female head 2. When the puncture wound no longer needs medication, the cotton swab 14 inside the ear puncture tube 12 can be removed, so that the inside of the wound can be in contact with the outside air through multiple cotton swab grooves and the through hole in the middle of the ear tag male head ring 11, allowing the wound to be ventilated and promoting wound healing.

[0049] Example 2, as shown in the appendix Figures 1-5 As shown, the outer surface of the puncture outer tube 16 is covered with a hemostatic cotton layer 17. Hemostatic drugs can be applied to the outer surface of the hemostatic cotton layer 17. After puncture, the inner side of the wound comes into contact with the hemostatic cotton layer 17, and hemostatic drugs can be applied to the inner side of the wound. A hand-tightening part 18 is provided on the outer surface of the puncture outer tube 16. After puncture, the puncture outer tube 16 can be unscrewed through the hand-tightening part 18.

[0050] Example 3, as shown in the appendix Figures 1-14 As shown, the bottom end face of the ear-piercing post 12 and the bottom face of the ear tag female head ring 21 are equipped with an anti-detachment structure 3 that can be interlocked with each other. When the ear tag female head ring 21 is threaded on the outside of the ear-piercing post 12, the ear tag male head 1 and the ear tag female head 2 can be locked together by the anti-detachment structure 3 to prevent them from falling off or being maliciously removed.

[0051] Example 4, as shown in the appendix Figures 6-14 As shown, the bottom of the ear tag head ring 21 is equipped with a drug supply structure 4 that can communicate with the upper cotton column 14. When the ear tag head ring 21 is threaded on the outside of the ear tube 12 and the anti-dislodgement structure 3 is locked, the drug supply structure 4 can pass through the anti-dislodgement structure 3 and communicate with the upper cotton column 14, so that the drug liquid inside the drug supply structure 4 can be transported from the head to the inside of the upper cotton column 14.

[0052] Example 5, as shown in the appendix Figures 1-14 As shown, the anti-dislodgement structure 3 includes a conical platform 31 coaxially fixed to the bottom of the ear-piercing tube post 12, and an anti-dislodgement column 32 coaxially fixed to the bottom of the ear tag head ring 21. The anti-dislodgement column 32 has a conical groove 33 at the center of its top surface that matches the conical platform 31. The outer conical surface of the conical platform 31 has an annular anti-dislodgement groove 34. The conical surface of the conical groove 33 has multiple anti-dislodgement sliding grooves 35. Each anti-dislodgement sliding groove 35 has an anti-dislodgement wedge 36 with a sloping top that is radially slidably installed within it. A wedge spring 37 connected to the anti-dislodgement wedge 36 is installed inside the anti-dislodgement sliding groove 35. When the ear tag head ring 21 is threaded onto the outside of the ear tube post 12, the conical platform 31 enters the conical groove 33 and fully abuts against it. The conical platform 31 pushes the anti-disengagement wedge 36 into the anti-disengagement sliding groove 35 and compresses the wedge spring 37. When the conical platform 31 and the conical groove 33 are fully abutted, the annular anti-disengagement groove 34 is flush with the height of the multiple anti-disengagement sliding grooves 35. Under the elastic force of the wedge spring 37, the multiple anti-disengagement wedges 36 spring into the annular anti-disengagement groove 34, thereby achieving the locking between the conical platform 31 and the anti-disengagement post 32. At this time, the ear tag head ring 21 cannot be unscrewed in reverse, thus achieving the anti-disassembly effect.

[0053] Example 6, as shown in the appendix Figures 7-14 As shown, the drug supply structure 4 includes a drug supply cylinder 41 fixedly installed at the bottom of the ear tag head ring 21. The drug supply cylinder 41 contains anti-inflammatory liquid. The top surface of the drug supply cylinder 41 has a cylindrical recessed part 42 in the middle. The anti-dislodgement column 32 is located inside the recessed part 42. A drug supply tube 43 is coaxially fixedly installed in the middle of the bottom surface of the recessed part 42. The top end of the drug supply tube 43 passes through the anti-dislodgement column 32 and is placed inside the ear tag head ring 21.

[0054] A plurality of drug supply holes 44 are provided between the inner and outer walls of the top of the drug supply tube 43. A drug supply cotton swab 45 is installed inside the drug supply tube 43, and the top of the drug supply cotton swab 45 extends into the plurality of drug supply holes 44. The bottom end of the drug supply cotton swab 45 passes through the bottom surface of the recess 42 and is placed inside the drug supply cylinder 41. The drug supply cotton swab 45 can absorb anti-inflammatory liquid.

[0055] Example 7, as shown in the appendix Figures 6-8As shown, a female cap 46 is threaded onto the inner side of the ear tag female head ring 21 via an internal thread 22. A drug supply tube sealing insertion hole 47 is provided in the middle of the bottom surface of the female cap 46. When the female cap 46 is screwed onto the inner side of the ear tag female head ring 21, the top end of the drug supply tube 43 is inside the drug supply tube sealing insertion hole 47, thereby sealing the multiple drug supply holes 44.

[0056] Example 8, as shown in the appendix Figures 1-14 As shown, a drug supply hole 48 is provided between the bottom surface of the conical platform 31 and the bottom surface inside the ear-piercing tube 12. A cotton column insertion hole 49 is provided in the middle of the bottom surface of the upper cotton column 14. The drug supply tube 43 can be inserted into the drug supply hole 48 and the cotton column insertion hole 49, so that the drug supply cotton strip 45 extending into several drug supply holes 44 comes into contact with the upper cotton column 14, so that the anti-inflammatory liquid absorbed inside the drug supply cotton strip 45 can be absorbed by the upper cotton column 14, thereby reducing inflammation on the inside of the wound.

[0057] Example 9, as shown in the appendix Figures 1-5 , Figure 9 , Figure 10 , Figures 12-14 As shown, an internal threaded ring 5 is coaxially fixedly installed on the top surface of the male ear tag ring 11. An external threaded ring 6 is installed on the inner thread of the internal threaded ring 5. A male screw cap 7 is fixedly installed on the top of the external threaded ring 6. A cotton column connecting block 8 is fixedly connected to the top of the cotton column 14. The top of the cotton column connecting block 8 is placed inside the external threaded ring 6. Multiple cotton column inserts 9 are installed on the inner wall of the external threaded ring 6. Multiple cotton column slots 10 are opened on the outer surface of the cotton column connecting block 8 to engage with the cotton column inserts 9. The cotton column inserts 9 and the cotton column slots 10 are tightly inserted. When it is necessary to remove the cotton column 14, the male screw cap 7 can be unscrewed. When the male screw cap 7 is lifted, the cotton column connecting block 8 and the cotton column 14 can be removed together. Then, the cotton column connecting block 8 is pulled off from the multiple cotton column inserts 9 and discarded. Finally, the male screw cap 7 is screwed back onto the internal threaded ring 5.

[0058] The male screw cap 7 has ventilation holes 71 on both the upper and lower sides. A ventilation mesh 72 is installed inside the ventilation holes 71. The middle part of the ear-piercing tube 12 after the cotton wool column 14 is removed is open and contacts the outside air through the ventilation mesh 72. At the same time, the ventilation mesh 72 can prevent foreign objects from entering the ear-piercing tube 12.

[0059] Example 10, as attached Figures 1-14As shown, annular buffer air cushions 01 are installed on the bottom surface of the male ear tag ring 11 and the top surface of the female ear tag ring 21. When the male ear tag 1 and the female ear tag 2 are installed on the ear, the buffer air cushions 01 on both sides of the ear come into contact with the ear skin and can form a protective ring on the outside of the wound to prevent foreign objects from entering the wound. Multiple ear tag clamp positioning grooves 02 are provided on the outer surface of the male ear tag ring 11 so that the male ear tag ring 11 and the ear tag clamp can be adapted and installed.
