Description

Technical Field

[0001] This utility model relates to the field of pig welfare structures, and more particularly to a structure for pigs to rub against their itch. Background Technology

[0002] In large-scale pig farming, pigs' scratching behavior is not only a manifestation of physiological needs, but also an important factor affecting animal welfare and production performance. However, existing pig scratching devices generally have the following technical problems: Existing technologies generally remain at the level of physical friction and fail to address the pathological mechanisms of pig itching. Pig itching originates from ectoparasites or skin inflammation, but traditional equipment cannot simultaneously achieve itching relief and drug intervention. For example, the brush-like structure disclosed in Chinese patent CN216415576U can only remove dirt and cannot release deworming liquid in a targeted manner during the friction process. This results in pigs needing to receive an additional artificial medicated bath after itching, increasing the labor intensity. Utility Model Content

[0003] The purpose of this utility model is to provide a pig rubbing structure in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pig scratching structure, comprising a fixed cylinder, wherein a plurality of scratching strips are installed in a circular array on the outer side of the fixed cylinder, a liquid supply component for storing anti-itch liquid is installed on the upper part of the fixed cylinder, a follower component is rotatably arranged outside the liquid supply component, and a power gain component that drives the follower component is installed inside the fixed cylinder, wherein the power gain component controls the spraying of anti-itch liquid in the liquid supply component.

[0005] As a further description of the above technical solution: the liquid supply assembly includes a liquid storage cylinder installed at the upper port of the fixed cylinder, and a plurality of connecting pipes are installed in a ring array on the outer side of the liquid storage cylinder, and atomizing nozzles are installed at the outer ports of the plurality of connecting pipes.

[0006] As a further description of the above technical solution: a sealing cap is threadedly installed at the feed port of the liquid storage cylinder.

[0007] As a further description of the above technical solution: the follower component includes a rotating ring rotatably mounted on the top of the liquid storage cylinder, and a rotating rod rotatably mounted through the center of the liquid storage cylinder. The rotating rod is coaxially and fixedly connected to the rotating ring. Several contact strips are installed in a ring array on the outer side of the rotating ring. A bevel gear that drives the power gain component is fixedly installed on the lower side of the outer surface of the rotating rod.

[0008] As a further description of the above technical solution: the power gain component includes a fixed frame that is fixedly installed inside the fixed cylinder. Two sleeves are symmetrically installed on the upper front side of the fixed frame. A rotating rod is rotatably installed on the lower front side of the fixed frame. A bevel gear two that meshes with the bevel gear one is fixedly installed on the front side of the outer surface of the rotating rod. A connecting plate is fixedly installed on the rear side of the outer surface of the rotating rod.

[0009] As a further description of the above technical solution: the two sleeves are connected to the liquid storage cylinder through a second connecting pipe. One-way valve two is installed at one end of the two connecting pipes that penetrate into the liquid storage cylinder. One-way valve one is installed through the upper side of the two sleeves. Pistons are slidably installed on the inner side of the two sleeves. Hinged rods are rotatably connected between the two pistons and the connecting plate.

[0010] As a further description of the above technical solution: a magnetic ring I is glued to the outer side of each of the two sleeves, and two magnetic rings II, which are opposite in polarity to the magnetic ring I, are glued to the two pistons respectively. Two springs are respectively connected and abut against the inner side of each of the two pistons and the two sleeves.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: As the pig scratches itself, the follower component drives the power gain component to reciprocate, which in turn continuously pressurizes the liquid supply component. This allows the anti-itch liquid in the liquid supply component to be sprayed onto the outside of the fixed cylinder and onto the pig scratching itself. This ensures that the anti-itch liquid is precisely applied to the area where the pig is scratching, thus effectively relieving the pig's itching. When the pig scratches itself, the follower component can only rotate back and forth with a small amplitude. This small amplitude of kinetic energy is not enough for the power gain component to generate a continuous and effective pressure. The power gain component can increase the kinetic energy, thereby enabling it to stably pressurize the liquid supply component and ensure that the antipruritic liquid is smoothly sprayed onto the pig on the outside of the fixed cylinder.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 - Figure 4 As shown, the present invention provides a pig rubbing structure, including a fixed cylinder 1, a plurality of rubbing strips 11 are installed in a circular array on the outside of the fixed cylinder 1, a liquid supply component 3 for storing anti-itch liquid is installed on the upper part of the fixed cylinder 1, a follower component 4 is rotatably arranged outside the liquid supply component 3, and a power gain component 5 that is driven by the follower component 4 is installed inside the fixed cylinder 1, and the power gain component 5 controls the spraying of anti-itch liquid in the liquid supply component 3. In practical use, the fixed cylinder 1 and the rubbing strip 11 form an uneven outer surface. The staggered uneven structure can fit the rubbing area of ​​the pig's body. During the rubbing process, the follower component 4 drives the power gain component 5 to reciprocate, so that the power gain component 5 continuously pressurizes the liquid supply component 3. This allows the anti-itch liquid in the liquid supply component 3 to be sprayed onto the outside of the fixed cylinder 1 and onto the pig rubbing itself, thus effectively relieving the pig's itch. During the rubbing process, the follower component 4 can only rotate back and forth with a small amplitude. This small amplitude of kinetic energy is not enough for the power gain component 5 to form a continuous and effective pressure. The power gain component 5 can increase the kinetic energy, so that it can stably pressurize the liquid supply component 3 and ensure that the anti-itch liquid is smoothly sprayed onto the pig on the outside of the fixed cylinder 1.

[0016] Specifically, the liquid supply assembly 3 includes a liquid storage cylinder 31 installed at the upper port of the fixed cylinder 1. Several connecting pipes 32 are installed in a ring array on the outside of the liquid storage cylinder 31. Atomizing nozzles 321 are installed at the outer ports of the several connecting pipes 32. A sealing cap 33 is threadedly installed at the feed port of the liquid storage cylinder 31. Opening the sealing cap 33 allows the antipruritic liquid to be poured into the reservoir 31 for use. When the power gain component 5 is in operation, the sealing cap 33 must be placed over the liquid inlet of the reservoir 31. After the power gain component 5 pressurizes the reservoir 31, the liquid is atomized and sprayed onto the outside of the fixed cylinder 1 and onto the pig through the atomizing nozzle 321.

[0017] Specifically, the follower component 4 includes a rotating ring 41 rotatably mounted on the top of the liquid storage cylinder 31, and a rotating rod 43 rotatably mounted through the shaft of the liquid storage cylinder 31. The rotating rod 43 is coaxially and fixedly connected to the rotating ring 41. Several contact strips 42 are installed in a ring array on the outer side of the rotating ring 41. A bevel gear 431 that drives the power gain component 5 is fixedly installed on the lower side of the outer surface of the rotating rod 43. When the pig scratches itself, it causes the contact bar 42 to rotate back and forth slightly. As the contact bar 42 rotates, it drives the bevel gear 431 through the rotating ring 41, which in turn drives the power gain component 5 to pressurize the liquid supply component 3.

[0018] Specifically, the power gain component 5 includes a fixed frame 51 fixedly installed inside the fixed cylinder 1. Two sleeves 52 are symmetrically installed on the upper front end of the fixed frame 51. A rotating rod 53 is rotatably installed on the lower front end of the fixed frame 51. A bevel gear 532 that meshes with bevel gear 431 is fixedly installed on the front outer surface of the rotating rod 53. A connecting plate 531 is fixedly installed on the rear outer surface of the rotating rod 53. Both sleeves 52 are connected to the liquid storage cylinder 31 through connecting pipe 2 55. One-way valve 2 551 is installed at one end of each connecting pipe 2 55 that penetrates into the liquid storage cylinder 31. One-way valve 1 525 is installed through the upper side of each sleeve 52. Piston 521 is slidably installed inside each sleeve 52. Hinged rods 56 are rotatably connected between each piston 521 and connecting plate 531. Two magnetic rings 523 are glued to the outer sides of the two sleeves 52, and two magnetic rings 524 that are opposite in polarity to the magnetic rings 523 are glued to the two pistons 521 respectively. Two springs 522 are respectively connected between the two pistons 521 and the inner sides of the two sleeves 52. The first bevel gear 431 meshes with the second bevel gear 532, which drives the rotating rod 53 to rotate. When the rotating rod 53 rotates, it pushes the second magnet ring 524 back and forth through the hinge rod 56. In this way, the two magnet rings 524 push the air in the two sleeves 52 into the liquid storage cylinder 31. After the air pressure in the liquid storage cylinder 31 increases, the antipruritic liquid inside can be sprayed out through the atomizing nozzle 321. When the magnet ring 2 524 reciprocates, external air is supplied into the sleeve 52 through the one-way valve 1 525, and the antipruritic liquid in the liquid storage cylinder 31 is prevented from entering the sleeve 52 through the one-way valve 2 551. When piston 521 on one side compresses spring 522 on the same side, magnet ring 524 on piston 521 on the other side approaches magnet ring 523 on the same side. Thus, magnet ring 524 and magnet ring 523 repel each other due to their opposite polarity. The dynamic synergistic force formed by the tension of spring 522 and the repulsive force between magnet ring 523 and magnet ring 524 ultimately creates an active gain.

[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
