A livestock auto-injector

Abstract

The invention discloses an automatic injector for livestock, which comprises a syringe, a limiting plate, an electric push-pull mechanism and a trigger mechanism. The lower end of the injection cylinder is connected with a needle, and a piston is installed in the injection cylinder, and the piston is connected with a piston rod. The electric push-pull mechanism is installed on the injection cylinder, and can drive the piston rod to move through electric power to inject animals. , the limiting plate is installed on the end of the injection cylinder close to the needle, and the limiting plate is provided with a needle hole for the needle to pass through, the trigger mechanism is installed on the end of the limiting plate that is in contact with the livestock, and is pressed Control the action of the electric push-pull mechanism to inject or draw medicine. Once the animal shakes greatly, causing the needle to fall off, it will leave the touch block, thereby releasing the forward rotation button, and automatically stop the injection, so that the liquid medicine will not be spilled, avoiding waste, more reasonable, no need to manually stop, and more timely .

Description

technical field [0001] The invention relates to the technical field of livestock automatic injectors, in particular to a livestock automatic injector. Background technique [0002] Our country imports a lot of meat products from foreign countries every year, such as pork, beef, etc., and the annual volume is very large. Now the country encourages the development of aquaculture. For the breeding industry, one of the most troublesome problems is that livestock are sick. Once sick, it may cause virus infection, leading to the death of the entire farm livestock and causing great losses. Vaccines, or timely injection of drugs when sick, to avoid spreading and affecting other livestock. There are many livestock in the farm. Manual injection requires a lot of time and manpower, which reduces labor intensity and work efficiency. Therefore, there is an automatic injection. However, there is also a problem with the automatic injection. The body is easy to twist, causing the needle t...

Problems solved by technology

There are many livestock in the farm. Manual injection requires a lot of time and manpower, which reduces labor intensity and work efficiency. Therefore, there is an automatic injection. However, there is also a problem with the automatic injection. The body is easy to twist, causing the needle to come off, and the automatic injection has not stopped, so the liquid medicine will be wasted. Avoid wasted syringes
