The gas-condition for discharging really is reacted more.
Preferably, the length of the communicating pipe is more than 20 centimetres.Anti- mixed effect can be improved to improve the true of sample
Reality.
Preferably, the communicating pipe extends along the inner surface of the roof of the gas receiver.
The utility model also includes at least two connecting rods, and one end of the connecting rod is fixed in one with the threaded rod
Rise, the other end is provided with briquetting, and vertically extending thread head is provided with the downside of the briquetting, the thread head is arranged with company
Lug, the engaging lug are fixed together with the gas receiver.It is convenient when storage cylinder is separated with threaded rod.
Preferably, the thread head is threaded with pulling block, the pulling block is located at the lower section of the engaging lug.Can turn over
Turn threaded rod and the gas receiver being inserted in soil is extracted.
The utility model tool has the advantage that：Operation is convenient；Independent sampling can be carried out to the gas discharged in soil；
The uniformity and authenticity of the gaseous sample collected is good.
Description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Stereochemical structure enlarged diagrams of the Fig. 2 for lid.
In figure：It is table top 1, screwed hole 11, gas receiver 2, base 21, lid 22, sawtooth 23, engaging lug 24, communicating pipe 25, close
Blocking 26, aspirating hole 27, threaded rod 3, handle 31, connecting rod 4, briquetting 41, thread head 42, pulling block 43, support feet 6.
Specific embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of building soil release gas sample collecting mechanism, including table top 1 and gas receiver 2.
Gas receiver 2 is located at the lower section of table top 1.Gas receiver 2 includes that base 21 and sealing are removably connected on base
Lid 22.Base 21 is the cylindrical shape that upper and lower ends are all open.The upper end of 22 cap base 21 of lid.On the lower surface of base 21
It is provided with some sawtooth 23 circumferentially distributed along gas receiver.
Table top 1 is provided with screwed hole 11 and support feet 6.Screwed hole 11 is inlayed for thread bush and is formed on the playing surface 1.Screwed hole 11
It is connected with vertically extending threaded rod 3.Threaded rod 3 and base 21 are coaxial.The upper end of threaded rod 3 is provided with handle 31.Spiral shell
The lower end of rasp bar 3 is same to be provided with 3 connecting rods 4.The circumference of 2 connecting rods 4 threadingly bar 3 is uniformly distributed.The upper end of connecting rod 4 is same
