The utility model discloses can be used for collecting goat expired gas to a learn methane content among the goat expired gas, it has simply as a result, characteristics such as convenient to use that is used for subsequent gas composition survey, thereby succinct quick.

Description

A kind of goat breathing gas harvester
Technical field
This utility model relates to a kind of goat breathing gas harvester.
Background technology
Animal breath gas usually comprises the information that some are important, such as exhalation CO2Amount and suction O2Amount ratio can react the basal metabolic state of animal, and the change of expiration total amount is likely to react the physiological status of animal.For ruminant, also include methane gas content in another one important information, i.e. exhaled gas.Ruminant tumor gastric fermentation can produce the greenhouse gases with methane as representative, and methane is as world's second largest greenhouse gases, and its greenhouse effect is 25 times of carbon dioxide, and its discharge capacity is also in cumulative year after year.Whole world 9%C02, 37%CH4, 65%N20 is caused by animal husbandry, and wherein ruminant discharges nearly 80,000,000 tons of methane every year, accounts for whole world domestic animal methane emission 97%.Therefore, methane discharge of ruminant controls to be increasingly becoming current study hotspot.Its meaning is: 1) fundamentally improves ruminant feed utilization rate, improves cultivation efficiency;2) reduce methane discharge of ruminant, effectively reduce aquaculture greenhouse gas emission, control to contribute for Global Emissions of Greenhouse Gas.
Goat is one of main ruminant, is also one of discharge of methane major source.Along with growth in the living standard, people, to meat products increase in demand, objectively make goat cultivation scale gradually expand, reduce goat discharge of methane, are also one of the main tasks that control of methane discharge of ruminant.Taking effective means to measure methane content in goat breathing gas, set out discharge of methane counter for research controls to be significant.
Summary of the invention
The purpose of this utility model is to provide a kind of goat breathing gas harvester, for measuring the content of methane in breathing gas, thus controls to provide research means base support for goat discharge of methane.
A kind of goat breathing gas harvester, including rubber face mask and the breathing cylinder being located on rubber face mask, described breathing cylinder is provided with air inlet pipe and escape pipe, the end of described escape pipe is provided with transfer atmospheric collection bag and little gas sampling bag, is equipped with a gas circulation automatic valve in described air inlet pipe and escape pipe.
The T-shaped rubber piston that described gas circulation automatic valve by metal washer, is located in metal washer and the gag lever post for preventing T-shaped rubber piston from coming off in metal washer form.
This utility model may be used for being collected goat exhaled gas, and measures for gas componant subsequently, thus succinctly quickly knows methane content in goat exhaled gas.The features such as it is simple that this utility model has result, easy to use.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1-rubber face mask, 2-breathe cylinder, 3-air inlet pipe, 4-escape pipe, 5-transfer atmospheric collection bag, the little gas sampling bag of 6-, 7-gas circulation automatic valve (71-metal washer, 72-T shape rubber piston, 73-gag lever post).
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment further illustrates this utility model.
Embodiment: as shown in Figure 1, a kind of goat breathing gas harvester, can be with the rubber face mask 1 closely fitted at goat mouth and nose including one, rubber face mask 1 is provided with the breathing cylinder 2 of hard, described breathing cylinder 2 is provided with air inlet pipe 3 and escape pipe 4, and the end of described escape pipe 4 is provided with transfer atmospheric collection bag 5 and little gas sampling bag 6.It is equipped with a gas circulation automatic valve 7, the T-shaped rubber piston 72 that described gas circulation automatic valve 7 by metal washer 71, is located in metal washer 71 and the gag lever post 73 for preventing T-shaped rubber piston 72 from coming off in metal washer 71 in described air inlet pipe 3 and escape pipe 4 to form.
Described metal washer 71 is positioned at air inlet pipe 3 and the stage casing of escape pipe 4, the lower end cylinder of described T-shaped rubber piston 72 just falls in metal washer 71, the round pie medicated cap (diameter, more than the inner ring diameter of metal washer 71, is slightly less than air inlet pipe 3 and the internal diameter of escape pipe 4) of T-shaped rubber piston 72 upper end is fitted on metal washer 71.The distance that described gag lever post 73 is positioned between the top of metal washer 71, and metal washer 71 is less than the entire length of T-shaped rubber piston 72.
During use, rubber face mask 1 is fitted in goat face, and hitch with cord and to prevent from coming off, then adjust air inlet pipe 3 and the direction of escape pipe 4, make the gas circulation automatic valve 7 in pipe consistent with airflow direction, open the air inlet air-stopping valve of transfer atmospheric sampler bag 9, close the air-stopping valve of gas outlet, during goat air-breathing, the T-shaped rubber piston 72 in air inlet pipe 3 can leave metal washer 71 under the effect of air-flow and negative pressure, and now gas gets enter into breathing cylinder 2.
When goat is exhaled, T-shaped rubber piston 72 in air inlet pipe 3 can touch again metal washer 71 under the effect of air-flow and pressure, air inlet pipe 3 is made to close, T-shaped rubber piston 72 in escape pipe 4 can leave metal washer 71 under the effect of air-flow simultaneously, so that the gas of exhalation enters transfer atmospheric collection bag 5.
During sampling, opening air outlet valve and the intake valve of little gas sampling bag 6 of transfer atmospheric collection bag 5, gas enters little gas sampling bag 6, until being completely filled with.
