The patent document of 206002336 U of Publication No. CN discloses a kind of for detecting the full-automatic of Subgrade Compaction
Sampler, which uses power unit with soil sample placement unit to the vertical incision of roadbed to be measured progress, using high-pressure air source
Soil sample is cut off, unit is finally extracted using soil sample and takes out soil sample.For this device not using seal protection, when sampling, needs work
Make the vertical handheld handle of personnel, there is security risk, and soil sample is easily splashed；Depth selection by rule of thumb, lacks accuracy entirely.
Invention content
The purpose of this utility model is to provide a kind of Subgrade Compactions to test drawing out soil equipment, its sampling part sets cylinder and prevents
Soil sample is splashed, and equipped with fixing device and depth indication device, sampling is safe, accurately.
The technical solution of the utility model is as follows：
A kind of Subgrade Compaction tests drawing out soil equipment, it is made of motor, drilling pipe, displacement reading device and fixing device；
Above-mentioned motor peripheral hardware electric motor protecting shell, motor lower end are connected with drilling pipe, and lower part sets grinder in drilling pipe, and grinder lower end is bores
Tooth；The fixing device is support plate of the band there are four wheel, and on the securing means equipped with screw thread upright bar, motor housing is through connecting rod
Connection screw thread upright bar, screw thread upright bar connect swinging handle through changement, and shift scale is set before screw thread upright bar, shift scale
Lower end is fixed on the supporting plate, and upper end is connected with screw thread upright bar top, and across connecting rod, and above-mentioned connecting rod is read equipped with displacement
Take device；Motor is connected by connecting line with gasoline engine generator.
Above-mentioned grinder is made of three truncated cone-shaped steel bodies, is mutually 120 DEG C of distributions, apart from drilling pipe bottom end plane 3~
5cm。
The utility model has the advantage of：1st, while the present apparatus is by boring tooth coring, the grinder inside drilling pipe
Soil sample is crushed, convenient for the progress of subsequent operation；Drilling pipe seals, and operating personnel need to be only in side control swinging handle
Can, safety does not also fall soil, conducive to health.Shift scale and displacement readers are also equipped with, convenient for accurately controlling depth selection.2、
The present apparatus is simple in structure, is easy to make, and support plate is equipped with push rod and handle ring, has wheel under plate, easy to remove, facilitates multiple spot
Sampling.

The specifically used process of the utility model is as follows：
1) device is transported to roadbed scene to be measured, wheel is rotated to above support plate, is selected according to project situation
Drilling pipe diameter and soil sample depth connect fixed drilling pipe.
2) drilling pipe is slowly displaced downwardly to by field personnel by swinging handle bores tooth and drills through face perpendicular contact with soil sample and be
Only, while displacement initial point is read.
3) dynamical system is connected, subgrade soil is carried out to drill through crushing, vertical direction must be kept in drilling pipe folding process.
4) when reaching displacement terminal, stop swinging handle 3 to 5 seconds.Then reversed slowly swinging handle so that drilling pipe is gradual
Subgrade soil is detached from, during displacement initial point to be achieved, closes dynamical system, after drilling pipe is stopped rotating, continues swinging handle, until
Tooth pitch is bored from soil body plane certain altitude.
Drilling pipe internal residual soil sample is cleared up, and be packed into hermetic bag together with soil sample in ditch using hairbrush.
Subsequent step is operated according to sand replacement method testing regulations.
