Abstract
The utility model discloses can use in agricultural fertilization, pesticide application technology field. It is concrete for a gaseous collection system who is arranged in the field soil, including handle, valve, drilling rod, pedal pad, transmission pipe, cone. Cone recess evenly distributed has miniature aperture, and rubber tube and a valve of fixed activated carbon pipe are equipped with to the top of transmission pipe, and the gaseous sample of collecting is adsorbed in the effect of activated carbon pipe, returns the laboratory desorption and for the analysis, guarantees to preserve the long period, has guaranteed the accuracy of data. Have a pedal pad that can move about on the drilling rod, it has two functions: (1 ) miscellaneous function, with pedal this position inserting darker sampling location with the sampling tube, (2) fixed function is carved with the yardstick on the protection tube, just can the accuracy get the gaseous sample of this soil layer degree of depth during to a certain scale with the pedal pad is fixed. The utility model discloses simple structure, convenient to use, low in cost, the result is accurate reliable.
Description
Technical field
The utility model belongs to a kind of gaseous sample collector be applied in soil, specifically a kind of device collecting gaseous sample in the soil of different depth for field, be specially adapted to agricultural chemicals and the fertilizer that can be applied to easily gasification and distillation, as: the fumigant of soil disinfection is (as Celfume, iodomethane, chloropicrin, DMDS, 1,3-dichloropropylene etc.) and the agricultural material such as liquefied ammonia, be a kind of fast, safety, the device collecting different soils advanced gas sample can be applied to efficiently, accurately, reliably.
Background technology
Protectorate cultivation develop rapidly and the continuous farming of high added value crop also result in the serious generation of soil-borne disease insect pest while increasing income for peasant, the Yield and qualities of crop is produced serious influence.Current solution continuous cropping, alleviate soil-borne disease and the most direct way occurs carry out soil-fumigating exactly.Conventional soil fumigant mostly easily gasifies and becomes gas and then spread in soil.But, the difference of the such as biomass content of different soils, the physicochemical property of pH and contained nutrient etc., make the distribution situation of fumigant in soil and reach now also unknown.Based on this, develop the utility model, the utility model is exactly under field condition, measure the degree of depth and radius that different fumigant spreads in different soils, for the method for application and use amount using different fumigant makes theoretical reference in the future.
Utility model content
The key issue that will solve of the present utility model: avoid the foreign gas in air to be mixed into sampler, utilizes the escaping gas in charcoal absorption soil and avoids it to escape, and guarantees in soil depth sampling accurately.
The technical solution of the utility model is: one is applied to soil gas sample collector.
This utility model device comprises handle, valve, drilling rod, pedal pad, transfer tube, conical head.Long one meter of described drilling pipe, be fixed with the handle that a length is 30 centimetres, there is in it axial through emptying aperture, a conical head is had bottom drilling rod, the recess average mark of conical head is furnished with the aperture that 6 diameters are 1 millimeter, internal diameter is that the transfer tube of 3 millimeters is axially through with in drilling pipe, has a proofed sleeve for fixing activated carbon tube on transfer tube top, pedal pad that can be movable with one on drilling pipe.
Described being applied to inside activated carbon tube that soil gas sample collection apparatus is furnished with is equipped with activated charcoal, activated carbon tube suitable for reading airtight, end opening is open at connection proofed sleeve place, and effect is that in absorption soil, volatile gas reduces and escapes due to it and the experimental error that causes and avoid the foreign gas in air to be mixed into sampler.
The described junction being applied to transfer tube top proofed sleeve and activated carbon tube in soil gas sample collection apparatus is furnished with a valve, valve is opened when drilling pipe is inserted into privileged site, volatile gas will be tightly held by activated carbon, and guarantees the accuracy sampled when darker sampling spot.
In laboratory conditions with suitable organic reagent by the described escaping gas desorb being applied to charcoal absorption inside activated carbon tube that the gas sample apparatus in soil is furnished with, for the analysis of next step experiment.
Described be applied to the movable pedal that soil gas sample collection apparatus is furnished with and be lined with two functions: (1) subsidiary function, stopple coupon can be inserted into darker sample position with this position of pedal, (2) fixed function, drilling pipe is carved with the scale that unit is centimetre to conical head aperture place to handle place, just accurately can get the gaseous sample of this soil depth when pedal pad being fixed to a certain scale.
Described be applied to handle that soil gas sample collection apparatus is furnished with and operator can be made to be inserted in soil layer by described device easily go.
The described drilling pipe being applied to soil gas sample collection apparatus is stainless steel structure, enhances its corrosion resistance intensity, can be widely used in the soil of number of different types, the serviceable life of extension fixture.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further.Following embodiment should be understood only be not used in for illustration of the present invention and limit the scope of the invention.
As shown in Figure 1: a kind of Simple soil gaseous sample collector device of the present embodiment, comprise drilling rod 5, in the middle of described drilling rod, there is axial pass-through holes 8, the point of described drilling rod has one group of transfer tube 6 be connected with described axial pass-through holes, the top of described drilling rod has the valve 3 be connected with described transfer tube, described proofed sleeve 2 is connected with activated carbon tube 1, a conical head 7 is also connected to bottom described drilling rod, the aperture that 6 diameters are 1 millimeter is furnished with at the depressed part average mark of conical head, volatile gas is exactly through transmitting and then being tightly held by activated carbon from this aperture.
The course of work being applied to the gas sample collector in soil in the present embodiment is: first determine sampling spot and sampling depth, fix the position of pedal pad, drilling rod is extend into the inside will monitoring soil, open the valve on proofed sleeve, in soil, volatile gas will enter into transfer tube by the aperture on conical head, under the attractive force effect of activated charcoal, volatile gas slowly will rise and be tightly held by activated carbon.Balance and take off activated carbon tube in-80 DEG C of Refrigerator stores after 30 minutes, go back to laboratory to be measured.The method detected activated carbon tube is placed in 20ml headspace sampling bottle, selects suitable organic extraction reagent by the sample desorb of charcoal absorption, qualitative, quantitative with GC-MS.
The utility model structure is simple, low cost of manufacture, corrosion resistance is strong, be a kind of device that can be applied to collection different soils advanced gas sample fast, safely, efficiently, accurately, reliably, the diffusion of volatile matter in soil in multiple soil can be detected.
