There is the first distance, straight line and institute where the second direction leaf margin of the helical blade between the axis of straight line and the drilling rod
Stating between the axis of drilling rod has second distance, and the numerical difference of first distance and the second distance is the eccentric screw
The eccentricity value of blade, the first direction leaf margin is respectively at the opposite side of the drilling rod with the second direction leaf margin, described
Have between the outer wall of the inwall of soil sample barrel and the drilling rod and receive provincialism.
A kind of above-mentioned electric geotome, ring-shape fixing flange, the hand handle are fixed with the fuselage of the motor
Body and the annular is connected to the connecting rod between body and the ring-shape fixing flange including annular.
A kind of above-mentioned electric geotome, the lower end of the drilling rod are provided with pointed cone head, the surface tool of the pointed cone head
There are multiple conical surfaces triangular in shape.
A kind of above-mentioned electric geotome, the eccentricity value of the eccentric screw blade are 2~3mm, the soil sample barrel
Interior barrel dliameter be adapted to the diameter of the eccentric screw blade.
A kind of above-mentioned electric geotome, the motor are servomotor.
The beneficial effects of the utility model are：Electric earth drill of the present utility model is fetching earth in use, first by soil sample barrel
It is set on drilling rod, drilling rod is pierced into underground, put down soil sample barrel after certain depth is got, then by drilling rod and soil sample barrel one
Work of fetching earth can be completed by playing taking-up.Electric earth drill is by setting eccentric screw blade so that during drilling, the hole position drilled through has
There is the aperture slightly larger than eccentric screw blade diameter, facilitate soil sample barrel to put down, because soil sample barrel is adapted to eccentric screw blade, make
It can must be successively limited at receiving in provincialism for soil sample barrel from top to bottom according to different depth by the soil on eccentric screw blade band,
After soil sample barrel is extracted, the layering of internal sampling soil is constant, and is not easy the soil sample that is scattered when soil sample barrel is extracted, and takes
Soil sample is not easy to obscure, and the DATA REASONING for sampling soil is accurately reliable.

Embodiment
To make to make the utility model further understanding, referring to Figure of description and specific embodiment to this practicality
It is new to be described further：
As shown in Figure 1 to Figure 3, the utility model discloses a kind of electric geotome, including motor 1, connect with motor 1
The drilling rod 2 connect and the soil sample barrel 4 being movably set on drilling rod 2.Motor 1 is connected with hand handle 7, and soil sample barrel 4 passes through iron chains 8 and hand
7 connections, it can prevent soil sample barrel 4 from losing.The lower section of drilling rod 2 is provided with the eccentric screw blade 3 to fetch earth.As shown in Fig. 2 edge
The length direction of drilling rod 1, is had between the straight line L1 at the place of first direction leaf margin 31 and the axis L2 of drilling rod 2 of helical blade 3
There is the first distance d1, have second between the straight line L3 at the place of second direction leaf margin 32 and the axis L2 of drilling rod 2 of helical blade 3
Distance d2.First distance d1 and second distance d2 numerical difference are the eccentricity value of eccentric screw blade 3, first direction leaf margin 31 with
