Gas collecting pipeline for collecting methane discharged from ruminant rumen

The utility model discloses a gas collecting pipeline for collecting methane discharged from ruminant rumen. Gas production pipeline comprising main body, wherein the main body gas production pipelinecomprises a gas production hose and a gas flow rate control device connected with the gas outlet end of the gas production hose; according to the ruminant rumen methane gas collecting device, gas generated by ruminant belching enters the main body gas collecting pipeline, and the flow speed of the gas in the pipeline is controlled, so that the ruminant rumen methane gas collecting device has theadvantages that ruminant rumen methane gas can be stably and accurately collected, operation is easy, ruminant esophagus is protected, and it is guaranteed that the gas can be continuously and stablycollected. 本实用新型公开了一种收集反刍动物瘤胃甲烷排放的气体收集管路，包括主体采气管路，所述主体采气管路包括采气软管和与所述采气软管的出气端连接的气体流速控制装置，本实用新型所提供的方案反刍动物"嗳气"所出的气体进入所述主体采气管路，通过控制管路内的气体的流速，从而带来能够稳定准确收集反刍动物瘤胃甲烷气体而且操作简单、保护反刍动物食道、确保气体可以持续稳定收集的有益效果。
