Description

Technical Field

[0001] This invention belongs to the technical field of pig welfare equipment, specifically relating to an efficient pig rubbing device. Background Technology

[0002] Currently, numerous documents have disclosed devices for pigs to scratch, such as: the scratching device for pig farming disclosed in existing document CN216415576U, which includes a fixed plate, which is a rectangular plate structure, with several connecting plates on both sides of the fixed plate. The connecting plates are fixed to the walls of the pigsty by bolts. An installation plate is provided on the front side of the horizontal plate, and a scratching device is provided on the front side of the installation plate; the scratching pig pen disclosed in existing document CN205213721U includes a pig pen body, which is surrounded by walls on all four sides. One wall has a gate, which is welded from steel bars. At least one wall has a scratching device fixed on the inner side, which includes a base plate and a protrusion on the base plate.

[0003] However, existing scratching devices typically only allow pigs to scratch themselves, but do not effectively relieve itching; they only address the superficial problem of scratching. Research and practice show that improving pig comfort through single scratching sessions is mostly effective in the short term, and pigs usually scratch intermittently multiple times. Therefore, it is necessary to develop a device that can effectively prevent pigs from scratching intermittently and repeatedly. Furthermore, since the itching sites for pigs are usually localized, existing scratching devices suffer from low efficiency in relieving itching. In many cases, a single scratching session can take more than twenty seconds, leading to the device's susceptibility to damage. Improving the efficiency of scratching for relieving itching and extending the lifespan of scratching devices are current technical challenges. Summary of the Invention

[0004] In view of the technical problems mentioned in the background art, the purpose of this invention is to provide an efficient device for pigs to rub their itch.

[0005] The present invention adopts the following technical solution.

[0006] A highly efficient rubbing device for pigs includes a rubbing part, which includes several toothed pieces fixedly mounted on a column. All the toothed pieces overlap and are arranged close together in the height direction, and the tips of the teeth on adjacent toothed pieces are staggered. The thickness of each toothed piece is no more than 5mm.

[0007] Furthermore, several through holes are provided on the toothed plate, the diameter of which is no greater than 3mm, and the through holes on adjacent toothed plates are staggered.

[0008] Furthermore, several pits are arranged in an array on the surface of the toothed plate, with the diameter of the pits not exceeding 1 mm and the depth of the pits not exceeding 0.3 mm.

[0012] Furthermore, the top toothed plate has a retaining ring along its edge, and the top toothed plate and the retaining ring together form a container for temporarily storing the antipruritic liquid.

[0013] As a preferred option, the tooth height of each toothed piece should not exceed 5mm.

[0014] As a preferred embodiment, the uprights are made from the vertical pipes on the limit rails or partitions; when two limit rails are side by side, the uprights are made from two vertical pipes on the two limit rails that are close to each other.

[0015] As a preferred option, mounting holes are coaxially provided on the upper and lower horizontal tubes of the limit bar, and the column is inserted and fixed in the mounting holes.

[0016] Beneficial effects: The rubbing device provided by this invention can not only effectively prevent pigs from rubbing themselves intermittently and repeatedly, and reduce the number of times pigs rub themselves within a specific time period, but also significantly improve the efficiency of rubbing to relieve itching. It can reduce the time for a single rubbing by a pig to less than ten seconds, and also significantly improve the service life of the rubbing device. More importantly, the rubbing device provided by this invention can achieve precise rubbing to relieve itching in local areas of the pig, improving the comfort and targeting of the pig during the rubbing process.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0022] Combination Figures 1 to 3 As shown, a high-efficiency rubbing device for pigs includes a rubbing part, which includes several toothed pieces 2 fixedly mounted on a column 1. The bottom end of the column 1 is provided with a mounting flange 11. The column 1 is fixedly installed in the pigsty. All the toothed pieces 2 are overlapped and arranged close together in the height direction. The lowest toothed piece 2 is supported and limited on the ring platform of the column 1, and the tooth tips 3 on adjacent toothed pieces 2 are staggered. The thickness of each toothed piece 2 is 5mm, and the tooth height of each toothed piece 2 is 4mm.

[0023] In this embodiment, three uniformly arranged through holes 4 are provided on the toothed plate 2. The diameter of the through holes 4 is 3mm, and the through holes 4 on adjacent toothed plates 2 are staggered. Several pits 5 are arranged in an array on the surface of the toothed plate 2. The diameter of the pits 5 is no greater than 1mm, and the depth of the pits 5 is no greater than 0.3mm. The pits 5 are made on the surface of the toothed plate 2 by steel needle pressing. Steel needle pressing refers to pressing the surface of the toothed plate 2 with a steel needle under a set pressure.

[0024] In this embodiment, two grooves 6 are axially provided on the column 1, and a protruding ridge 7 adapted to the groove 6 is provided on the side wall of the mounting hole of the toothed piece 2. After the protruding ridge 7 is inserted into the groove 6, the rotation of the toothed piece 2 is restricted. A retaining spring 8 is provided on the upper surface of the top toothed piece 9. The retaining spring 8 is fitted on the column 1 to axially limit the toothed piece 2.

[0025] In this embodiment, an anti-itch medication supply tube is provided above the rubbing area. The outlet of the anti-itch medication supply tube is located directly above the top toothed plate 9. The anti-itch medication supply tube is connected to an anti-itch medication supply system, and the anti-itch medication can be adimethicone diluted solution. A retaining ring 10 is provided on the edge of the top toothed plate 9, and the top toothed plate 9 and the retaining ring 10 together constitute a container for temporarily storing the anti-itch medication.

[0026] Comparative Example 1: A common pig scratching post includes a column 1 fixedly installed in the pigsty. The outer wall of the column is provided with several protrusions and grooves, which are similar to the rough structure of the tire surface.

[0027] Comparative Example 2: A pig scratching device includes a scratching part, which comprises several toothed pieces 2 fixedly mounted on a column 1. The column 1 is fixedly installed inside the pigsty. All the toothed pieces 2 overlap and are arranged close together in the height direction, and the tips 3 of each row of teeth on all the toothed pieces 2 face the same direction. The thickness of each toothed piece 2 is 5mm, and the tooth height of each toothed piece 2 is 4mm. This pig scratching device is essentially no different from a conventional scratching post and cannot effectively prevent pigs from intermittently scratching themselves repeatedly.

[0028] A four-month-old fattening pig was found to have itchy skin. Tests on the itchy areas revealed a large number of mites and other microorganisms. The pig was first placed in a space equipped with the pig scratching post described in Comparative Example 1. It was observed that the pig scratched itself up to 6 times a day, with each scratching session lasting 22-27 seconds. The next day, the pig was moved to a space equipped with the high-efficiency pig scratching device described in Example 1. It was found that the pig scratched itself only once that day, with a scratching time of only 7 seconds. During the scratching process, medication was precisely delivered directly from the tip of the tooth plate 2 to the itchy area on the pig's skin.

[0029] The efficient pig scratching device from Example 1 was installed in a penned pigsty containing twenty five-month-old pigs. Observations showed that the pigs scratched themselves only twenty-three times on the first day, with each scratching session lasting no more than ten seconds. On the second day, they scratched themselves only five times. The pig scratching device from Comparative Example 2 was also installed in a penned pigsty containing twenty five-month-old pigs. Observations showed that the pigs scratched themselves twenty-two times on the first day, with each scratching session lasting between 20 and 30 seconds. On the second day, they scratched themselves twenty-three times.

[0030] The rubbing device provided in Example 1, due to its specific rubbing section and antipruritic liquid supply system, allows pigs to actively rub themselves by means of the staggered tooth tips on the toothed plates. It also guides the antipruritic liquid to be precisely applied / flowed to the rubbing area. During use, the antipruritic liquid is supplied to the container in the top toothed plate via the supply system. This liquid flows slowly down through the holes on the toothed plate and is temporarily stored. It further seeps slowly through the gaps between adjacent toothed plates, and some liquid is also temporarily stored in the pits on the toothed plates. When the pig rubs itself against the toothed plate, the gaps between adjacent toothed plates slightly widen under the rubbing force, allowing the liquid to flow smoothly to the rubbing area on the pig's body. The ingenious aspects of this solution include: the use of thin, stacked toothed plates to form a rubbing area, which works in conjunction with the medication system, effectively preventing pigs from rubbing themselves intermittently and repeatedly, and improving the efficiency of rubbing to relieve itching and the lifespan of the rubbing device; the staggered arrangement of the tooth tips on adjacent plates ensures full contact between the pig's body surface and multiple tooth tips, which facilitates changes in the gap between adjacent plates; the staggered arrangement of through holes on the plates and the several pits on their surfaces help guide the temporary storage and flow of the antipruritic medication, and prevent medication loss, ultimately improving the comfort and targeting of the pigs during the rubbing process.

[0031] The rubbing device provided in Example 1 can not only effectively prevent pigs from rubbing themselves intermittently and repeatedly, reducing the frequency of rubbing during a specific time period (the stage when the pig's body surface is itchy), but also significantly improve the efficiency of rubbing to relieve itching. It can shorten the time spent by pigs rubbing themselves once, and also significantly improve the service life of the rubbing device. With fewer rubbings and less frequency, the service life of the rubbing device will be extended. More importantly, the rubbing device in Example 1 can achieve precise rubbing to relieve itching in local areas of the pig, improving the comfort and targeting of the pig during the rubbing process. Example 2

[0032] A high-efficiency rubbing device for pigs includes a rubbing part. The main structure of the rubbing part is shown in Figures 1-3. The rubbing part includes several toothed pieces 2 fixedly sleeved on a column 1. All toothed pieces 2 overlap and are arranged close together in the height direction, and the tooth tips 3 on adjacent toothed pieces 2 are staggered. The thickness of each toothed piece 2 is 4mm, and the tooth height of each toothed piece 2 is 5mm.

[0033] In this embodiment, three uniformly arranged through holes 4 are provided on the toothed plate 2. The diameter of the through holes 4 is 2.5 mm, and the through holes 4 on adjacent toothed plates 2 are staggered. A plurality of pits 5 are arranged in an array on the surface of the toothed plate 2. The diameter of the pits 5 is no greater than 1 mm, and the depth of the pits 5 is no greater than 0.3 mm. The pits 5 are formed on the surface of the toothed plate 2 by sandblasting.

[0034] In this embodiment, two grooves 6 are axially provided on the column 1, and a protruding ridge 7 adapted to the grooves 6 is provided on the side wall of the mounting hole of the toothed piece 2. The toothed piece 2 is restricted from rotating after the protruding ridge 7 is inserted into the groove 6.

[0035] In this embodiment, an antipruritic liquid supply tube is provided above the rubbing area. The outlet of the antipruritic liquid supply tube is located directly above the top toothed plate 9. The antipruritic liquid supply tube is connected to an antipruritic liquid supply system, and the antipruritic liquid can be a traditional Chinese medicine antipruritic. A retaining ring 10 is provided on the edge of the top toothed plate 9. The top toothed plate 9 and the retaining ring 10 together constitute a container for temporarily storing the antipruritic liquid.

[0036] In this embodiment, combined with Figure 4 As shown, mounting holes are coaxially provided on the upper horizontal tube 12 and lower horizontal tube 13 of the pig holding pen, and the upright 1 is inserted and fixed in the mounting holes. Example 3

[0037] A highly efficient itch-rubbing device for pigs, referring to Embodiment 2, differs from Embodiment 2 mainly in that: the upright 1 adopts the upright tube on the limiting fence. When the two limiting fences are side by side, the upright 1 adopts two upright tubes on the two limiting fences that are close to each other, and the toothed plate 2 is simultaneously fitted and fixed on the two upright tubes.
