Specific implementation manners

[0019] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] As Figures 1-5 shown, a kind of calving assistance device for cows of the present utility model includes a base 1. An inclined platform 10 is fixedly arranged on the upper side of the base 1. A hydraulic cylinder 11 is fixedly arranged on the upper side of the inclined platform 10. The output end of the hydraulic cylinder 11 is fixedly provided with an inclined hopper 12. Two round holes are symmetrically distributed in the front and back are opened on the left side of the inclined hopper 12. Two support rods 13 symmetrically distributed in the front and back are fixedly arranged on the upper side of the base 1. A round rod 14 is rotatably assembled on the upper sides of the two support rods 13. Two wire wheels 15 symmetrically distributed in the front and back are concentrically fixed on the round rod 14. Pulling ropes 16 are wound around the two wire wheels 15. One end of each of the two pulling ropes 16 is fixedly connected to the wire wheel 15. The other ends of the two pulling ropes 16 pass through the round holes and are fixedly provided with pulling rings 17. A control member matching the round rod 14 is installed on the upper side of the base 1;

[0021] When the present utility model is in use, the user first pushes the device through the universal wheels on the lower side of the base 1 to move the device to a suitable position, and then starts the hydraulic cylinder 11 to make the output end of the hydraulic cylinder 11 extend, thereby adjusting the height of the inclined hopper 12. The user then operates the control member to make the round rod 14 rotate. The round rod 14 synchronously drives the two wire wheels 15 to rotate. The two wire wheels 15 release the pulling ropes 16. The user puts the pulling ring 17 on the leg of the calf to be born. The user then operates the control member to make the round rod 14 rotate. The round rod 14 synchronously drives the two wire wheels 15 to rotate. The two wire wheels 15 wind the pulling ropes 16 on the surface of the wire wheels 15. At the same time, the pulling ropes 16 pull the calf to be born out of the cow's body through the pulling rings 17 to ensure the normal calving of the cow;

[0022] Furthermore, the calf born first falls into the inclined hopper 12 to protect the newly born calf and ensure the health of the calf;

[0023] In this utility model, the pull ring is passed through the legs of the calf to be delivered, and then the round rod is rotated by the control member. The round rod synchronously drives two wire wheels to rotate. The wire wheels wind the pull rope on the surface of the wire wheels, and the pull ring is used to deliver the calf to be delivered. The structure is simple and convenient to use, reducing the labor intensity of the workers.

[0024] The control member includes a first gear 18 which is concentrically fixed at one end of the support rod 13 where the round rod 14 extends backward. A motor 19 is installed on the upper side of the base 1, and an output shaft of the motor 19 is concentrically fixed with a second gear 20 which meshes with the first gear 18.

[0025] When using this utility model, the output shaft of the motor 19 drives the second gear 20 to rotate. The second gear 20 synchronously drives the engaged first gear 18 to rotate, driving the wire wheel 15 to rotate, so as to wind and release the pull rope 16, which is convenient to use without manual rotation by the user.

[0026] A long groove is formed on the right side of the base 1. A long plate 21 is slidably assembled in the long groove. An electric telescopic rod 22 is fixed on the upper side of the long plate 21. An output shaft of the electric telescopic rod 22 is fixed with an arc plate 23. A roller 24 is installed on the lower side of the long plate 21. Transverse grooves are formed on the front and rear sides of the long groove. First screws 25 are slidably assembled in the two transverse grooves. Blocks matching with the first screws 25 are fixed on the front and rear sides of the long plate 21. Two square cavities 26 which are symmetrically distributed front and rear are formed inside the base 1. Turbines 27 are concentrically fixed at one ends of the two first screws 25 extending rightward into the square cavities 26. A circular cavity communicating with the two square cavities 26 is formed inside the base. A rotating shaft 28 matching with the circular cavity is rotatably assembled inside the base 1. Worms 29 meshing with the turbines 27 are concentrically fixed on the front and rear sides of the rotating shaft.

[0027] When this utility model is not in use, the left side of the long plate 21 is located inside the long groove. The output shaft of the electric telescopic rod 22 shrinks to the shortest, the output end of the hydraulic cylinder 11 shrinks to the shortest, and the pull rope 16 is wound on the surface of the wire wheel 15, making the pull ring 17 abut against the inner wall of the inclined hopper 12, so that the volume of the device shrinks to the minimum, which is convenient for storage.

[0028] When using this utility model, the user first rotates the rotating shaft 28. The rotating shaft 28 drives the worms 29 on both sides to rotate. The worms 29 synchronously drive the two turbines 27 to rotate. The turbines 27 drive the two first screws 25 to rotate. The first screws 25 drive the long plate 21 to slide in the long groove through the blocks, so that the long plate 21 extends out of the long groove. After the long plate 21 extends a certain length, the electric telescopic rod 22 is started. The electric telescopic rod 22 drives the arc plate 23 to rise, making the arc plate 23 abut against the cow, so as to further limit and fix the device. At the same time, the arc plate 23 can provide a certain supporting force for the cow, which is convenient for the cow to give birth.

[0029] A vertical groove communicating with the rear side cavity 26 is formed on the upper side of the base 1. A third gear 30 meshing with the second gear 20 is rotatably assembled on the side wall of the vertical groove. A fourth gear 31 meshing with the third gear 30 is fixedly arranged concentrically at the rear side of the rotating shaft 28.

[0030] When the utility model is in use, the user first moves the motor 19 backward. The output shaft of the motor 19 drives the second gear 20 to move synchronously. The second gear 20 disengages from the first gear 18 and meshes with the third gear 30. Then the user starts the motor 19, so that the output shaft of the motor 19 drives the third gear 30 to rotate through the second gear 20. The third gear 30 drives the fourth gear 31 to rotate synchronously. The fourth gear 31 drives the rotating shaft 28 to rotate synchronously. The first screw rod 25 is driven to rotate through the turbine 27 and the worm 29, so as to control the sliding of the long plate 21. There is no need for the user to manually rotate the rotating shaft 28. After the operation on the long plate 21 is completed, the user moves the motor 19 forward again, so that the second gear 20 on the output shaft of the motor 19 meshes with the first gear 18, and then the motor 19 drives the wire wheel 15 to rotate to pull the calf to be born, so as to assist the cow in giving birth, reducing the labor intensity of the user and improving the convenience and smoothness of the device.

[0031] A square groove 32 is formed on the upper side of the base 1. A second screw rod 33 is rotatably assembled in the square groove 32. A vertical block 34 matching with the second screw rod 33 is fixedly arranged on the lower side of the motor 19. The second screw rod 33 extends out of one side of the base 1 backward and is fixedly provided with a hand wheel 35 concentrically. The user drives the second screw rod 33 to rotate by rotating the hand wheel 35. The second screw rod 33 drives the vertical block 34 to move, so as to drive the motor 19 to move synchronously, which is convenient for moving the motor 19 and can limit the position of the motor 19 to ensure the smooth use of the device.

[0032] The above embodiments only exemplarily illustrate the principle and efficacy of the utility model, rather than limiting the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
