The invention will be further described below in conjunction with accompanying drawing and principle of work.
Embodiment
Referring to accompanying drawing 1, the composition of support rotating undisturbed soil sampling device of the present invention such as Fig. 1 comprise detachable handle 1, external thread drilling rod 2, A-frame 3, tapped drilling rod fixator 4, diameter adjustment plate and fixator 5, the soil sample overcoat is pressed into plate 6, soil sample overcoat set collar 7, roller type cutter stationary installation 8, roller type cutter 9, the fixed bar 10 of tripod, horizontal bubble 11, soil sample container 12 compositions such as grade.
The internal thread of the external thread of external thread drilling rod 2 and drilling rod fixator 4 cooperatively interacts, and drilling rod fixator 4 is with the A-frame 3 that supports and be used to show that the horizontal bubble 11 of levelling connects as one;
Aperture adjustment plate and fixator 5, form by cutter fixed connector 41 and Y type cutter fixed head 42, it is arranged on the lower end of external thread drilling rod 2, has cutter regulating tank 43 on the cutter fixed head 42 of Y type, and aperture adjustment plate and fixator 5 rotate with external thread drilling rod 2;
The soil sample overcoat is pressed into plate 6 and is fixed on and has aperture adjustment plate and fixator 5 lower ends, is used to compress soil sample container 12;
One roller type cutter stationary installation 8, it is connected with the cutter fixed head 42 of the Y type of aperture adjustment plate and fixator 5, be fixed with cutter 9 and at least one earth pillar overcoat set collar 7 on this roller type cutter stationary installation 8, this earth pillar overcoat set collar 7 is used for fixing soil sample container 12; Cutter 9 is connected the lowermost end of roller type cutter stationary installation 8;
The specification of earth pillar overcoat set collar 7 has multiple, and present embodiment adopts 2.
One soil sample container 12 is used for the undisturbed soil sampling, is fixed on during use on the earth pillar overcoat set collar 7.
The 42 equal angles settings of Y type cutter fixed head have cutter regulating tank 43 on the cutter fixed head 42 of Y type, cutter 9 can be regulated.
A-frame 3 is telescopic, and fixed bar 10 is arranged at its bottom.
The soil sample overcoat is pressed into bearing 61 on the plate 6, this bearing 61 can be with 2 rotations of external thread drilling rod, the soil sample overcoat be pressed on the plate 6 also have three equal angles settings be pressed into plate radius adjustable plate 62, to be pressed into plate radius adjustable plate 62 by set bolt 63 is fixed on the soil sample overcoat and is pressed on the plate 6, be pressed into plate radius adjustable plate 62 beyond bearing 61, main plaing compresses 12 effects of soil sample container, and it does not rotate with external thread drilling rod 2.
