Description

Technical Field

[0001] The utility model relates to the technical field of pig injections, in particular to a nitrogen spring for pig injections. Background Art

[0002] In the pig breeding process, due to the rampant diseases, newborn piglets need to be injected with dozens of vaccines from weaning to the nursery stage in order to gain immunity and improve survival rate. Some large-scale pig farms also need blood tonic injections and other health care drugs. Due to the large number of sows in large-scale pig farms, according to production procedures, thousands of pigs are born every day, and thousands of pigs need to be injected. Considering the problem of vaccine antibody interference, the actual number of injections is even larger. Technical personnel need to configure injections in advance, disinfect instruments, and finally chase and capture pigs, disinfect and inject. The whole process requires a large number of needles, which is relatively cumbersome. For this reason, we propose a nitrogen spring for pig injections. Utility Model Content

The one-third sector gear 53 is meshed with the rack 42. The input end of the motor 52 is electrically connected to the output end of the control switch 7. The liquid injection assembly 6 includes a liquid injection tube 61 and a sealing cover 62. Two corresponding liquid injection holes are provided at the right end of the circumferential surface of the installation barrel 1. The liquid injection tube 61 is fixed inside the liquid injection hole. The rear end of the circumferential surface of the liquid injection tube 61 is threadedly connected with the sealing cover 62.
