Bottom, probe tube are made of two semicircle sections of jurisdiction, and end cap is inserted into the lumen of probe tube and is connected by fixing screws, end cap
Bottom center at be provided with cylindrical limiting groove, end cover surface is provided with the gas vent with limiting groove perforation, the top of end cap
It is provided with connector slot, connector is embedded in connector slot, and through-hole, through-hole of the piston rod through connector are provided on the central axes of connector and end cap
It is inserted into cutting ring, the bottom of piston rod is fixed with piston, and piston bottom surface is concordant with the bottom surface of cutting ring, and the top surface of piston is equipped with
Retention bead, the outer diameter of retention bead and the internal diameter of limiting groove are equal.
Preferably, the quantity of the gas vent is not less than 2 and not 2 integer portion, and gas vent symmetrically opens up and end cap
Transition face on.
Preferably, the cutting ring is threadedly coupled with probe tube, and the basil inclined-plane of cutting ring and the angle of horizontal plane be 45 °~
60°。
Preferably, the piston is rubber piston.
The beneficial effects of the present invention are: the structure of the soil sampler is simple, can facilitate when mud drilling hole bottom takes soil will flow
The mud entered in soil sampler squeezes out soil sampler, prevents from sampling native failure;The soil sampler vacuum effect is more preferable simultaneously, can prevent from sampling
Soil is scattered during returning and mentioning and sampling is caused to fail, and samples soil and be easier to take out from soil sampler, improves soil extracting efficiency.
