The invention discloses a soil breakage type sampling device for
gaseous mercury in soil. The soil breakage type sampling device comprises a manual gas extraction pump. A
metal wire tube is communicated with an end of a first
silicone tube, a second
silicone tube is communicated with an end of the
metal wire tube, a dust filter is mounted on the second
silicone tube, a hollow shaft is communicatedwith an end of the second
silicone tube, a slide sleeve slidably sleeves the hollow shaft, a cover is mounted on the slide sleeve, a soil breaking mechanism is mounted on the lower portion of the hollow shaft and comprises a sleeve, the sleeve slidably sleeves the hollow shaft, a
drill bit portion is fixedly connected with the lower end of the hollow shaft, a pressing sleeve slidably sleeves thehollow shaft, and a sampling hole is formed in a side of the lower end of the hollow shaft. The soil breakage type sampling device has the advantages that users can acquire gas in the soil without taking out
drill bits during sampling, accordingly, the problem of inaccurate sample acquisition due to the fact that gas in air flow into gas in existing soil and is mixed with the gas in the existing soil can be solved, and the
gaseous mercury can be conveniently and quickly sampled by the soil breakage type sampling device during sampling.
