Description
Technical field
The utility model relates to a kind of sampling instrument, particularly a kind of field gas automatic sampling instrument.
Background technology
Along with the development of research work, the more and more refinement of research of the growing environment of researcher to field crops. Not only study soil constituent, fertilizer type, the fertilization time in plant growth field, the weather conditions, temperature humidity, illumination that also relate to every day in process of crop growth often, intensity of illumination etc. Along with the further refinement of research work, researcher proposes to sample to the air in plant growth field, to study the reciprocal effect in field air and process of crop growth. Traditional field gas sampling generally adopts artificial sample, need researcher's timing to go to field manually to sample, such sample mode man's activity is large, and in order to make sample gas more representative in the extensive area of field, often need to arrange multi-point sampling, often cause the difference in first sampled point and post-sampling point life period, in the time that regional extent is larger, more than the time of first sampled point and the time interval of last sampled point even reach half an hour. And in the time that needs are repeatedly sampled, need researcher to remove Field sampling at set intervals, and waste time and energy, and need to repeatedly interrupt the work in laboratory, affect operating efficiency.
Summary of the invention
The purpose of this utility model is to solve field gas artificial sample to waste time and energy, and unmanageable problem of time, and a kind of field gas automatic sampling instrument is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of field gas automatic sampling instrument, comprise the sampling tracheae, air pump, sampling magnetic valve, the sampling airbag that connect successively, described air pump and sampling magnetic valve are also connected with timer, described air pump rear side is also connected with the air bleeding valve in parallel with the magnetic valve of sampling, and air bleeding valve is opened by pressure check valve. Timer can be set the sampling time, when to setting-up time, air pump and sampling magnetic valve are opened and are carried out gas sampling, in order to reduce the impact of gas on sample gas in gas circuit, before sampling, need gas circuit to rinse, way is that air pump starts prior to sampling magnetic valve. When sampling magnetic valve do not open and air pump start time, between air pump and sampling magnetic valve, build the pressure, cause increased pressure, air bleeding valve both sides produce pressure reduction and automatically open exhaust, gas circuit is rinsed, and after sampling magnetic valve is opened, air pump is inflated in airbag, air bleeding valve both sides pressure reduction reduces under setting value, exhaust valve closure. The air bleeding valve of this device adopts opened by pressure, compares the air bleeding valve by Electromagnetic Control, and the check valve of opened by pressure also plays the effect of protection, prevents from that pipeline from building the pressure to cause gas circuit seepage. And adopt pressure control to replace Electromagnetic Control, and simplify control circuit, without considering the not control problem of conducting simultaneously of sampling magnetic valve and air bleeding valve, simplify control structure.
As preferably, a described air pump correspondence arranges multiple sampling magnetic valves, and each sampling magnetic valve is all connected with sampling airbag, and sampling magnetic valve is subject to Timer Controlling to postpone to open successively by setting. Timer is back off timer, can set initial time and interval time, from initial time, samples at regular intervals, realizes operatorless multi-period timing sampling.
As preferably, air pump is opened prior to sampling magnetic valve, after in sampling closed electromagnetic valve. Before each sampling magnetic valve is opened, air pump starts in advance, after each sampling closed electromagnetic valve, after air pump, closes, and gas circuit is rinsed.
As preferably, described air pump, sampling magnetic valve, set timer, in sampling casing, are also provided with battery and controller in sampling casing, and battery is air pump, sampling magnetic valve, timer power supply. Air pump, sampling magnetic valve, timer are all connected and realize timing controlled with controller.
The utility model adopts the check valve of pressure control unlatching as air bleeding valve, and sampling gas path pipe is formed to protection, prevents from building the pressure; And pressure controlled air bleeding valve has been simplified control circuit, simplify the not control problem of conducting simultaneously of sampling magnetic valve and air bleeding valve.
