Abstract
The utility model relates to a grain stack data collector, which comprises a moisture sampling chamber, wherein a gas outlet duct is arranged on the moisture sampling chamber and a moisture sensor is arranged in the moisture sampling chamber. The moisture sampling chamber carries out gas sampling of specific depth positions through a gas valve and a depth setting gas sampling tube communicated with the gas valve, a temperature sensor is installed at a gas inlet on the tail end of the depth setting gas sampling tube and the temperature sensor and the gas valve are respectively connected with a control measurement circuit through conducting wires. The collector of the utility model comprises the moisture sampling chamber, the gas outlet duct is arranged on the moisture sampling chamber, the moisture sensor is arranged in the moisture sampling chamber, and the moisture sampling chamber carries out gas sampling of specific depth positions through the gas valve and the depth setting gas sampling tube communicated with the gas valve, so the moisture sensor does not need to be taken out when fumigating insect disinsection is carried out to grains, thereby, work load is reduced. Additionally, when local concentration in grain stacks is higher, fumigating gas can not be directly contacted with the moisture sensor because the moisture sensor is arranged in the moisture sampling chamber, thereby, the phenomenon that the moisture sensor does not work because of corrosion can be avoided.
Description
Technical field
The utility model relates to a kind of grain heap data collector.
Background technology
Grain heap moisture content, in the foodstuff preservation process, manual or the electronic sample instrument of the common employing of storage personnel is from different grain heap degree of depth skewer sample thiefs, use the ice detector device, detect the method for moisture content data and hand-kept, the relevant calculation machine is surveyed the water scheme also has the people in test and research, also carried out correlation test in some warehouses, its principle also is that the temperature and humidity sensor is put into the grain heap, obtain the measured point temperature, after the relative humidity data, definition and relevant grain kind equilibrium humidity expert database according to grain heap equilibrium humidity, converse the grain heap humidity (moisture content) of measured point, owing to humidity sensor can be worked under situation about being isolated from the outside unlike temperature sensor, thereby when grain is carried out fumigant insect killing, humidity sensor must be taken out, two drawbacks are arranged like this: (1) has increased managerial personnel's labor capacity; (2) behind the stifling gas that looses of grain, when humidity sensor is put into the grain heap and worked on, may make humidity sensor malfunctioning easily, thereby make whole survey water system cisco unity malfunction because the partial fumigating gas concentration is higher in the grain heap because of corrosion.
The utility model content
The purpose of this utility model is to provide a kind of labor capacity little, the grain heap data collector that measurement effect is good.
In order to achieve the above object, the technical solution of the utility model is to have adopted a kind of grain heap data collector, this collector comprises the humidity sampler chamber, the humidity sampler chamber is provided with escape pipe, in the humidity sampler chamber humidity sensor is housed, the humidity sampler chamber carries out the gas sample of certain depth position by the depthkeeping gas sample tube of air valve and connection thereof, and the terminal air intake opening place of depthkeeping gas sample tube is equipped with temperature sensor, and sensor and air valve link to each other with the control survey circuit by lead respectively.
General gas sensor also is housed in the humidity sampler chamber.
Described general gas sensor is oxygen sensor and carbon dioxide sensor.
On the escape pipe of humidity sampler chamber, aspiration pump is housed.
On the humidity sampler chamber, be communicated with three gas sample tubes that the degree of depth is different at least, air valve be installed respectively in connection place of each gas sample tube.
Outside described each gas sample tube, also be with a stopple coupon outer tube, be evenly distributed with the air inlet micropore on the stopple coupon pipe overcoat wall.
Described stopple coupon outer tube is the continuous long more piece pipe that is spirally connected successively, and the longest end and the sampling thief of pipe are fixed together.
Described temperature sensor is a digital temperature sensor.
Because collector of the present utility model comprises the humidity sampler chamber, the humidity sampler chamber is provided with escape pipe, humidity sensor is arranged in the humidity sampler chamber, the humidity sampler chamber carries out the gas sample of certain depth position by the depthkeeping gas sample tube of air valve and connection thereof, like this, when grain is carried out fumigant insect killing, just humidity sensor need not be taken out, thereby significantly reduce workload; In addition, when local concentration was higher in the grain heap, because humidity sensor is arranged in the humidity sampler chamber, fumigating gas can directly not contact with humidity sensor, thereby has avoided humidity sensor because of the malfunctioning phenomenon of corrosion; On the humidity sampler chamber, be communicated with three gas sample tubes that the degree of depth is different at least, air valve be installed respectively, need not take out collector, promptly can be used for measuring the humidity and the temperature at diverse location place in connection place of each gas sample tube.
