[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail this application.
[0024] Example 1, see Figures 1 - 5, this embodiment provides a livestock and veterinary animal treatment observation device, including a transparent observation box 1. Pulley 2 is assembled around the bottom end of the transparent observation box 1. The assembly of the four groups of pulleys 2 can enable the staff to reduce the force required when moving the transparent observation box 1. A rectangular groove 3 is opened at the bottom end of the front surface of the transparent observation box 1. A leakage net frame 4 is assembled on the transparent observation box 1. The function of assembling the leakage net frame 4 on the transparent observation box 1 is that when the animals placed inside the transparent observation box 1 excrete, the feces can fall into the inner bottom end of the rectangular groove 3 through the leakage holes of the leakage net frame 4. The side surface of the transparent observation box 1 is fixedly connected with an L-shaped support rod 501 by bolts. The function of the L-shaped support rod 501 is to support the annular guide ring 505, and the function of the annular guide ring 505 is to guide the sliding of the annular gear ring 506, so as to prevent the sliding of the annular gear ring 506 from skewing and causing motion deviation. One end of the L-shaped support rod 501 far away from the transparent observation box 1 is fixedly connected with an annular guide ring 505. The annular gear ring 506 is slidably connected to the top end of the annular guide ring 505. A support plate 502 is fixedly connected to the side surface of the transparent observation box 1. The function of the support plate 502 is to support the use of the motor 503, so as to facilitate the work of the motor 503. A motor 503 is assembled on the top end of the support plate 502. The output shaft of the motor 503 is fixedly connected with a first gear 504. A support rod 507 is fixedly connected to the top end of the annular gear ring 506. The annular gear ring 506 meshes with the first gear 504. Therefore, when the first gear 504 rotates under the action of the motor 503, the annular gear ring 506 can be made to rotate. The top end of the support rod 507 is rotatably connected with a camera 508 through a universal joint 509. The top end of the support rod 507 is rotatably connected with a camera 508 through a universal joint 509. Therefore, the camera 508 can rotate in various directions under the action of the universal joint 509. Two extrusion blocks 510 are fixedly connected to both sides of the bottom end of the camera 508. A first hydraulic cylinder 511 is fixedly connected to the bottom end of the annular guide ring 505. During the rotation of the two extrusion blocks 510, they can sequentially squeeze the first hydraulic rod 512 or the second hydraulic rod 513. One end of the inside of the first hydraulic cylinder 511 is slidably connected with a first hydraulic rod 512 through a piston, and the other end of the inside of the first hydraulic cylinder 511 is slidably connected with a second hydraulic rod 513 through a piston. A cleaning component 6 for cleaning the feces of livestock is assembled inside the rectangular groove 3, and a storage component 7 for treating the feces of livestock is assembled inside the rectangular groove 3. The annular gear ring 506 meshes with the first gear 504. A total of six first hydraulic cylinders 511 are provided, and the six first hydraulic rods 512 and second hydraulic rods 513 are sequentially located on the movement trajectories of the two extrusion blocks 510.
[0025] In use, people first need to move the device to a position suitable for the use of the device, then open the observation box door at the top of the transparent observation box 1, and put the animal to be observed into the inside of the leakage net frame 4 inside the transparent observation box 1. At this time, turn on the switch of the motor 503 so that the output shaft of the motor 503 can drive the first gear 504 to rotate. At the same time, since the first gear 504 and the annular gear ring 506 are in a meshing state, when the first gear 504 rotates, the annular gear ring 506 can also rotate. When the annular gear ring 506 slides on the top of the annular guide ring 505, at this time, the annular gear ring 506 can drive the camera 508 to perform a circular motion along the outside of the transparent observation box 1. At the same time, during the process of the camera 508 moving driven by the annular gear ring 506, the two sets of extrusion blocks 510 at the bottom of the camera 508 respectively squeeze the first hydraulic rod 512 or the second hydraulic rod 513 in turn. When one of the first hydraulic rod 512 or the second hydraulic rod 513 is subjected to the extrusion force, at this time, the internal liquid pressure of the first hydraulic cylinder 511 increases, so that the other set of the first hydraulic rod 512 or the second hydraulic rod 513 can be pushed out, so as to act on the camera 508, so that the camera 508 rotates upward or moves downward under the action of the first hydraulic rod 512 or the second hydraulic rod 513, so that the camera 508 can swing up and down while sliding driven by the annular gear ring 506, so as to comprehensively observe the animals inside the transparent observation box 1, so as to facilitate the staff to observe the treatment situation of the animals.
[0026] Example 2, see Figures 1 - 8, on the basis of Embodiment 1, in the present application, the cleaning component 6 includes a fixing plate 604. The function of the fixing plate 604 is to support the rotational movement of the torsion spring rod 602. The fixing plate 604 is fixedly connected to the side surface of the transparent observation box 1. The torsion spring rod 602 penetrates through and is rotatably connected to the inside of the fixing plate 604. A second gear 603 is fixedly connected to the outer side of the torsion spring rod 602. A rack 601 is fixedly connected to the inner side of the annular gear ring 506. The rack 601 meshes with the second gear 603. Therefore, when the rack 601 slides, the second gear 603 can be made to perform a rotational movement. A rotating block 605 is fixedly connected to the bottom end of the torsion spring rod 602. A crushing rod 606 is fixedly connected to the side surface of the rotating block 605. The function of the crushing rod 606 is to crush the feces remaining on the bottom end inside the rectangular groove 3, so as to facilitate the further scraping operation of the scraper 609. A third gear 607 is fixedly connected to the outer side of the crushing rod 606. The third gear 607 meshes with the arc-shaped rack rod 610. Therefore, the third gear 607 can perform a rotational movement. A scraper 609 is fixedly connected to the side surface of the rotating block 605. An arc-shaped rack rod 610 is fixedly connected to the bottom end inside the rectangular groove 3. A special-shaped inclined block 608 is fixedly connected to the inside of the rectangular groove 3. Since there are operation blind spots in the rotational movements of the crushing rod 606 and the scraper 609, the special-shaped inclined block 608 is provided so that the feces can slide along the inclined surface end of the special-shaped inclined block 608 to the area where the crushing rod 606 and the scraper 609 can perform rotational movements. The rack 601 meshes with the second gear 603, and the third gear 607 meshes with the arc-shaped rack rod 610.
[0027] In use, on the basis of Embodiment 1, when the annular gear ring 506 rotates under the drive of the first gear 504, since the rack 601 and the second gear 603 are in a meshed state, when the annular gear ring 506 slides, the second gear 603 can be made to rotate. When the second gear 603 rotates, at this time, the torsion spring rod 602 can be made to rotate synchronously. When the torsion spring rod 602 rotates, it can drive the rotating block 605 to rotate synchronously. At the same time, the rotating block 605 can drive the crushing rod 606 and the scraper 609 to rotate synchronously. When the crushing rod 606 rotates, it can crush the solid matter of the animal excrement or the matter that is difficult to scrape through the crushing rod 606. At the same time, since the third gear 607 and the arc-shaped rack rod 610 are meshed, during the overall rotation of the crushing rod 606, it can also rotate itself, thereby enhancing the effect of the crushing rod 606. After the crushing rod 606 works, the scraper 609 can also follow and perform a synchronous scraping movement, so as to scrape the excrement on the inner bottom end of the rectangular groove 3, thereby cleaning the animal excrement. At the same time, when the annular gear ring 506 slides to a position where it is not meshed with the second gear 603, at this time, the torsion spring rod 602 can drive the rotating block 605, the crushing rod 606 and the scraper 609 to perform an automatic reset operation under the action of its own resilience, and so on and so forth.
[0028] Embodiment 3, see Figures 1 - 9 , on the basis of Embodiment 1, the storage assembly 7 in the present application includes a second hydraulic cylinder 702. The second hydraulic cylinder 702 is fixedly connected to the inner bottom end of the rectangular groove 3. One end inside the second hydraulic cylinder 702 is slidably connected with a force-bearing rod 701 through a piston. When the force-bearing rod 701 is subjected to a squeezing force, at this time, the internal liquid pressure of the second hydraulic cylinder 702 increases, so that the pressure rod 703 can be extruded. The other end inside the second hydraulic cylinder 702 is slidably connected with a pressure rod 703 through a piston. The bottom end of the transparent observation box 1 is equipped with a storage box 706 for storing the animal excrement. A switch door 704 is hinged to the side of the storage box 706, and a switch door 704 is hinged to the side of the storage box 706, which is convenient for the staff to perform regular processing. The top end of the storage box 706 is elastically connected with an opening and closing plate 705 through a torsion spring. The force-bearing rod 701 is located on the movement track of the scraper 609.
[0029] In use, on the basis of Embodiment 1, when the crushing rod 606 and the scraper 609 swing, they can squeeze the force-bearing rod 701. At this time, when the force-bearing rod 701 is subjected to the squeezing force, the liquid pressure inside the second hydraulic cylinder 702 increases, so that the pressure rod 703 can be pushed out. When the pressure rod 703 is pushed out, it can act on the opening and closing plate 705, so that the opening and closing plate 705 can be opened towards the storage box 706 with the torsion spring as the hinge point, so that the scraped excrement can enter the inside of the storage box 706. At the same time, when the squeezing force of the scraper 609 on the force-bearing rod 701 disappears, at this time, the opening and closing plate 705 drives the opening and closing plate 705 to automatically reset under the action of the self-returning force of the torsion spring, so as to prevent the opening and closing plate 705 of the storage box 706 from being opened for a long time, emitting a stench and affecting the staff. At the same time, after a period of time, the staff can perform regular treatment by opening the switch door 704.
[0030] 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 person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
