The utility model is achieved through the following technical solutions, the utility model comprises bull stick, drilling rod, drilling pipe, drill bit and brill tooth, drilling rod upper end is connected with bull stick is vertical, drilling rod lower end connects drilling pipe top, drilling pipe bottom is provided with the drill bit of hollow, drill bit lower end connects at least two and bores tooth, in described drilling pipe, be provided with movable sampling ring, described drilling rod is established the hollow tubular structure of cavity in being, in drilling rod cavity, be provided with static line, drilling rod middle part is provided with the crank that can rotate, the front end of described crank is horizontally through the both sides of described drilling rod, described static line upper end is fixing on the leading portion of described crank, described static line lower end is through being divided at least 4 stock ropes that distribute along even circumferential after drilling rod cavity, described at least 4 stock ropes are fixedly connected sequentially downwards on described sampling ring and described drill bit.
As the further improvement of such scheme, in described drilling rod cavity, be provided with rope sling, static line passes in rope sling.
As the further improvement of such scheme, described drill bit and described sampling ring are provided with eyelet at the position of fixing described point of rope, and described point of rope is fixedly connected with described drill bit with described sampling ring by described eyelet.
As the further improvement of such scheme, described drilling rod is connected with bull stick by screw thread.
As the further improvement of such scheme, described drilling rod is movably connected by inside and outside matching thread by multiple drilling rod units.
As the further improvement of such scheme, described drilling pipe top is provided with tapped pipe platform, and described drilling rod bottom is provided with external thread, and described drilling rod is connected by screw thread with pipe platform, thereby is fixed in drilling pipe.
As the further improvement of such scheme, described drilling pipe is movably connected by inside and outside matching thread by multiple drilling pipes unit.
As the further improvement of such scheme, described drill bit is connected with drilling pipe by inside and outside matching thread.
As the further improvement of such scheme, described drilling rod and drilling pipe are provided with scale mark.
The utility model has the following advantages compared to existing technology:
(1) assembly and disassembly facilitates, is easy to carry about with one;
(2) field sampling is without using additional power supply;
(3) when drilling pipe is goed deep into sampled point soil, barrel is peeled away soil sample and Soil Surrounding, and in cylinder, soil sample keeps original shape, has ensured to gather and collect the integrality of pedotheque in overall process, is conducive to conventional pedotheque analysis of later stage;
(4) according to the scale mark being carved with on collector drilling rod and drilling pipe wall, can gather exactly the soil sample of desired depth, ensure representativeness and the experiment accuracy of soil sample;
(5) sample ring by drilling pipe and take out like a cork complete column soil sample, bore odontoid and also can adjust accordingly according to different geological conditions;
(6) opereating specification is little, has avoided the large area ecological disruptions such as the vegetation that mechanically actuated brings.
