Description

TECHNICAL FIELD

[0001] The application belongs to the field of breeding, and particularly relates to a semi-automatic sampling device for a pig house. BACKGROUND

[0002] In large-scale pig breeding, in order to obtain samples of important pathogens such as African swine fever and blue-ear disease, and contaminated samples, early diagnosis is achieved by frequently sampling the environment of the pig house. The existing sampling method is usually to directly enter each pig house by the breeder to collect the excrement and secretion of the pig, but this sampling method is not only low in efficiency, but also the breeder is easy to carry pathogenic microorganisms, thereby significantly increasing the probability of cross infection between the pig houses, and thus inevitably causing losses. Therefore, it is urgent to design a semi-automatic sampling device for a pig house, which can assist in sampling without entering the pig house, so as to achieve early detection, early sampling and early intervention measures for important pathogens such as African swine fever and blue-ear disease.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0026] Reference Figures 1-6The utility model provides a semi -automatic big cage sampler for pathogen sampling in pig house, including sampling gripper 1 and telescopic link 2, sampling gripper 1 includes the casing 11, and the casing 11 is connected to one end of telescopic link 2, and the sliding block 12 is slidably installed in the casing 11, and the sliding block 12 is shaped as a regular polygonal prism, and the rack 13 is fixedly connected on each side of the sliding block 12, and the gear 14 is arranged on the periphery of the sliding block 12 corresponding to the position of each side, and each gear 14 is rotatably installed on the casing 11 and is engaged with the corresponding rack 13, and the grab bar 15 is fixedly connected on the central axis of each gear 14, and the other end of the grab bar 15 is stretched out to the outside of the casing 11 through the strip hole on the casing 11, and the hydraulic rod 16 is fixedly installed in the inside of the side close to sampling gripper 1 of telescopic link 2, and the telescopic end of the hydraulic rod 16 is fixedly connected with one end of the sliding block 12. By controlling the extension and retraction of the hydraulic rod 16, the sliding block 12 can be driven to slide, thereby driving the gear 14 to rotate through the rack 13, and then the grab bar 15 can be driven to complete the extension and retraction action through the gear 14, so that the sample can be gripped and released.

[0027] Before actual sampling, the breeding personnel can set a disposable plastic bag on the sampling gripper 1, the bag opening of the plastic bag is fixed on the connection between the sampling gripper 1 and the telescopic link 2 through the rubber band, then the breeding personnel stands outside the big cage and holds the telescopic link 2 to stretch the sampling gripper 1 into the big cage, after aligning the target sample, pressing the operation button on the telescopic link 2, controlling the hydraulic rod 16 to retract, the sample can be gripped, after the gripping is completed, the sampling gripper 1 is moved out of the big cage, and the plastic bag on the sampling gripper 1 and the sample are unloaded together, then a new plastic bag is set again, and the sampling work of the next big cage can be carried out.

[0028] In the embodiment, the end face of the sliding block 12 away from the end of the hydraulic rod 16 is provided with a guide hole, the inner wall of the casing 11 is fixedly connected with a guide column 17 matched with the guide hole, and the guide column 17 is slidably installed in the guide hole. The guide column 17 can guide the sliding of the sliding block 12, so that the sliding block 12 is more stable during the sliding process, so as to ensure that the rack 13 on the sliding block 12 can always be precisely engaged with the gear 14.

[0029] In the embodiment, the cross section of the guide hole and the cross section of the guide column 17 are both rectangular, so that the rotation of the sliding block 12 can be prevented.

[0030] In the embodiment, the grab bar 15 is an L-shaped rod, and the end of the grab bar 15 outside the casing 11 is provided with a round head, so that the plastic bag set on the sampling gripper 1 can be avoided from being pierced.

[0031] In this embodiment, the shape of the slider 12 is a regular quadrangular prism, and the four sides of the regular quadrangular prism are fixedly connected with racks 13. The number of gears 14 is four, and the number of grab rods 15 is also four. Each gear 14 is engaged with the corresponding rack 13. In other embodiments, the shape of the slider 12 can also be a regular pentagonal prism, a regular hexagonal prism, etc. The shape of the slider 12 is adjusted according to the number of required installed grab rods 15. The more the number of grab rods 15, the stronger the grabbing ability of the sampling gripper 1.

[0032] In this embodiment, the outer surface of the shell 11 away from one end of the telescopic rod 2 is fixedly connected with a fixed column 18. The end surface of the fixed column 18 close to the shell 11 is provided with an annular fixed groove 19. The center part of the plastic bag sleeved on the sampling gripper 1 can be fixed on the fixed groove 19 by a rubber band, so that the middle part of the plastic bag can be close to the shell 11, thereby facilitating the grabbing of the sample.

[0033] In this embodiment, the telescopic rod 2 includes a first rod body 21 and a second rod body 22. Both the first rod body 21 and the second rod body 22 are made of PVC material, so that the telescopic rod 2 is more portable. Both the first rod body 21 and the second rod body 22 are hollow structures. One end of the second rod body 22 is slidingly installed in the inside of one end of the first rod body 21. The other end of the second rod body 22 is in communication with the shell 11. The hydraulic rod 16 is fixedly installed in the inside of the second rod body 22. A locking assembly is arranged at the connection between the first rod body 21 and the second rod body 22, for relatively fixing the first rod body 21 and the second rod body 22.

[0034] In this embodiment, the locking assembly includes a fixed sleeve 23 and a threaded sleeve 25. The fixed sleeve 23 is sleeved on the outside of the first rod body 21. The end of the fixed sleeve 23 close to the second rod body 22 is fixedly connected with a ring of locking pieces 24 arranged at intervals. The inner side surfaces of the locking pieces 24 are arc surfaces and surround the second rod body 22. The inner side surfaces of the locking pieces 24 are in contact with the outer surface of the second rod body 22. The outer surface of the locking piece 24 is provided with threads. The threaded sleeve 25 is threadedly connected to the outside of the ring of locking pieces 24.

[0035] In this embodiment, the thickness of the locking piece 24 gradually decreases from the end close to the first rod body 21 to the end away from the first rod body 21. The diameter of the threaded hole of the threaded sleeve 25 gradually decreases from the end close to the first rod body 21 to the end away from the first rod body 21. As the threaded sleeve 25 is gradually tightened on the locking piece 24, the pressing force of the locking piece 24 on the second rod body 22 gradually increases until the second rod body 22 is locked, thereby realizing the relative fixation between the first rod body 21 and the second rod body 22.

[0036] When the breeder is sampling, if it is found that the sampling position is too far away to achieve sampling, the threaded sleeve 25 can be loosened, so that the locking piece 24 loses the locking effect on the second rod body 22, at this time the second rod body 22 can be pulled out to make its length longer outside the first rod body 21, when adjusted to the appropriate length, the threaded sleeve 25 is tightened again, the first rod body 21 and the second rod body 22 are relatively fixed, at this time the sampling operation can be completed.

[0037] In the embodiment, a battery is internally installed at the end of the telescopic rod 2 away from the shell 11, the battery is used to supply power for the hydraulic rod 16, and a charging interface is arranged on the battery, so that the battery can be charged.

[0038] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application in any way, so any slight modification, equivalent change and modification made according to the technical essence of the present application to the above embodiment still belongs to the scope of the technical solution of the present application.
