[0025] When livestock need to be injected, the staff first ensures that the medicine bottle 22 contains the medicine liquid needed by the livestock, then the staff picks up the handle 1 and aligns the needle 11 with the part where the medicine is needed. When the positioning is completed, the staff pushes the handle 1 to make the needle 11 enter the body of the livestock. At this time, the handle 1 will drive the extension rod 2 to continue to move, so that the fixed seat 3 drives the medicine liquid push rod 4 and the guide rod 18 to move, and further move the medicine liquid push rod 4 along the injection chamber 7 to the top of the injection chamber 7, so that the medicine liquid push rod 4 pushes the medicine liquid inside the injection chamber 7. At this time, the pressure inside the injection chamber 7 increases. The injection chamber 7 is large, and the plug 19 and the plug 2 13 are squeezed. When the plug 2 13 is squeezed, the plug 2 13 and the medicine inlet chamber 12 conflict with each other, and the plug 2 13 cannot be displaced. When the plug 19 is squeezed, the medicine liquid inside the injection chamber 7 will push the plug 19 to displace the plug 19. At this time, the medicine liquid is injected into the livestock through the medicine outlet chamber 8 and the needle 11. When the injection is completed, the pressure inside the injection chamber 7 becomes smaller, and the elastic potential energy of the spring 10 causes the spring 10 to push the plug 19 to reset. At this time, the plug 19 seals the medicine outlet chamber 8 again. At the same time, when the medicine liquid When the push rod 4 and the guide rod 18 are pushed, the liquid medicine push rod 4 drives the block 16 to move along the inside of the sleeve 15, and the spring 3 17 is squeezed, and the guide rod 18 drives the block 20 to move along the inside of the sleeve 2 19, and the spring 4 21 is squeezed. After the drug administration is completed, the staff pulls the needle 11 out of the livestock. At this time, the elastic potential energy of the spring 3 17 and the elastic potential energy of the spring 4 21 causes the sleeve 2 19 and the sleeve 15 to drive the moving seat 6 to reset. At this time, the moving seat 6 drives the injection chamber 7 to reset, so that the liquid medicine push rod 4 The injection chamber 7 is pumped inside. When the medicine push rod 4 is pumped, the plug 1 9 and the medicine outlet chamber 8 conflict with each other, making the plug 1 9 unable to move, and the suction force provided by the medicine push rod 4 will drive the plug 2 13 to move inward along the medicine inlet chamber 12. At this time, the spring 2 14 is compressed, and the medicine in the medicine bottle 22 will be pumped into the medicine inlet chamber 12 through the medicine delivery tube 23. When the medicine reaches a certain amount, the pressure inside the injection chamber 7 is restored, so that the spring 2 14 elastically drives the plug 2 13 to reset, and the medicine inlet chamber 12 is sealed. At this time, the livestock can be injected again.
[0026] By pushing the handle 1, the medicine push rod 4 is displaced along the inside of the injection chamber 7, and the medicine is output to the livestock through the medicine outlet chamber 8. When the medication is completed, the staff pulls out the needle 11. At this time, the elastic potential energy of the spring three 17 and the spring four 21 causes the medicine push rod 4 to reset inside the injection chamber 7, and the reset of the medicine push rod 4 will pump a certain amount of medicine into the injection chamber 7 through the medicine inlet chamber 12 to prepare for the next injection. Compared with the traditional device, the device resets the medicine push rod 4 after the injection is completed through the setting of the spring three 17 and the spring four 21, and fills the injection chamber 7 with medicine at the same time, thereby avoiding the problem of frequent adding of medicine when performing multiple injection operations, effectively reducing the workload, and through the extension setting of the extension rod 2, the staff can keep a certain distance from the livestock during the injection operation, providing a certain safety guarantee.
[0027] A guide rod 18 is fixedly installed on the left side of the fixed seat 3 . There are two groups of guide rods 18 , which are located at the front and rear sides of the liquid medicine push rod 4 . Both groups of guide rods 18 are movably connected to the movable seat 6 .
[0028] Among them, a sleeve 2 19 is fixedly installed on the right side of the movable seat 6. There are two groups of sleeve 2 19, which are located at the front and rear sides of sleeve 1 5.
[0029] Among them, the outer walls of the two groups of guide rods 18 are fixedly installed with block 20, and the two groups of block 20 are located inside the sleeve 19. The inner wall of the sleeve 19 is elastically installed with spring 4 21, and the block 20 and the inner wall of the sleeve 19 are elastically connected through spring 4 21.
[0030] When the injection is completed, the staff pulls the needle 11 out of the livestock's body. At this time, the elastic potential energy of spring three 17 and the elastic potential energy of spring four 21 cause sleeve two 19 and sleeve one 5 to drive the moving seat 6 to reset. At this time, the moving seat 6 drives the injection chamber 7 to reset, causing the medicine push rod 4 to pump inside the injection chamber 7.
[0031] Among them, a medicine bottle 22 is detachably installed at one end of the extension rod 2, the top of the medicine bottle 22 is connected to the medicine delivery tube 23, one end of the medicine delivery tube 23 passes through the fixing ring 24 and is connected to the medicine inlet bin 12. There are two groups of fixing rings 24, both of which are fixedly installed on the outer wall of the extension rod 2.
[0032] When the staff pulls the needle 11 out of the animal's body, the liquid medicine in the medicine bottle 22 is output to the medicine inlet bin 12 through the medicine delivery tube 23 by pulling the liquid medicine push rod 4, and the two sets of fixing rings 24 are provided to prevent the medicine delivery tube 23 from falling off.
[0033] Among them, the outer wall of the injection chamber 7 is fixedly provided with observation grooves 15 , and there are two groups of observation grooves 15 located at the upper and lower sides of the injection chamber 7 .
[0034] The staff can observe the liquid medicine content inside the injection chamber 7 through the observation slot 15 .
[0035] The working principle and use process of this utility model:
[0036] When livestock need to be injected, the staff first ensures that the medicine bottle 22 contains the medicine liquid needed by the livestock, then the staff picks up the handle 1 and aligns the needle 11 with the part where the medicine is needed. When the positioning is completed, the staff pushes the handle 1 to make the needle 11 enter the body of the livestock. At this time, the handle 1 will drive the extension rod 2 to continue to move, so that the fixed seat 3 drives the medicine liquid push rod 4 and the guide rod 18 to move, and further move the medicine liquid push rod 4 along the injection chamber 7 to the top of the injection chamber 7, so that the medicine liquid push rod 4 pushes the medicine liquid inside the injection chamber 7. At this time, the pressure inside the injection chamber 7 increases. The injection chamber 7 is large, and the plug 19 and the plug 2 13 are squeezed. When the plug 2 13 is squeezed, the plug 2 13 and the medicine inlet chamber 12 conflict with each other, and the plug 2 13 cannot be displaced. When the plug 19 is squeezed, the medicine liquid inside the injection chamber 7 will push the plug 19 to displace the plug 19. At this time, the medicine liquid is injected into the livestock through the medicine outlet chamber 8 and the needle 11. When the injection is completed, the pressure inside the injection chamber 7 becomes smaller, and the elastic potential energy of the spring 10 causes the spring 10 to push the plug 19 to reset. At this time, the plug 19 seals the medicine outlet chamber 8 again. At the same time, when the medicine liquid When the push rod 4 and the guide rod 18 are pushed, the liquid medicine push rod 4 drives the block 16 to move along the inside of the sleeve 15, and the spring 3 17 is squeezed, and the guide rod 18 drives the block 20 to move along the inside of the sleeve 2 19, and the spring 4 21 is squeezed. After the drug administration is completed, the staff pulls the needle 11 out of the livestock. At this time, the elastic potential energy of the spring 3 17 and the elastic potential energy of the spring 4 21 causes the sleeve 2 19 and the sleeve 15 to drive the moving seat 6 to reset. At this time, the moving seat 6 drives the injection chamber 7 to reset, so that the liquid medicine push rod 4 The injection chamber 7 is pumped inside. When the medicine push rod 4 is pumped, the plug 1 9 and the medicine outlet chamber 8 conflict with each other, making the plug 1 9 unable to move, and the suction force provided by the medicine push rod 4 will drive the plug 2 13 to move inward along the medicine inlet chamber 12. At this time, the spring 2 14 is compressed, and the medicine in the medicine bottle 22 will be pumped into the medicine inlet chamber 12 through the medicine delivery tube 23. When the medicine reaches a certain amount, the pressure inside the injection chamber 7 is restored, so that the spring 2 14 elastically drives the plug 2 13 to reset, and the medicine inlet chamber 12 is sealed. At this time, the livestock can be injected again.
