The present invention also provides the installation methods of the lever firming formula earth boring auger device, will first bore lid 1-1 and brill when in use
Bar 2-4 is connected through a screw thread, then motion stops 3-1 and two drive rod 3-3 are hinged, then will be on two drive rod 3-3
End both passes through two that bore the lid upper end 1-1 across hole 1-3, then, installs hand lever 3-4, and torsional spring 3-5 is first fixed on lever and is connected
On spindle 2-6, then hand lever 3-4 is fixed on lever connecting shaft 2-6 by rivet again, then, then by hand lever 3-4 and
The upper end drive rod 3-3 is respectively fixedly connected with, and drill body 1-5 and handle 2-1 are then passed through the connection type of screw thread respectively again
It is connected to brill lid 1-1 and the upper end drilling rod 2-4, i.e. instrument installs.
The present invention also provides the application methods of the lever firming formula earth boring auger device, in field during soil sampling, experiment
Drill bit 1 need to be directed at sampling area by personnel, then both hands gripping handles 2-1, and both hands are firmly pressed downward, or can not be pushed in manpower
When other material resources can be used tap the blunt 2-3 of iron on handle, be gradually inserted drill bit 1 in the sampling soil body, until drill bit 1 reaches and takes
Sample depth once samples successfully；Then, earth boring auger device is above mentioned, by sampler bag mark label and is placed under it, sample collector
It is firmly rotated up hand lever 3-4, makes the end its hand lever 3-4 that drive rod 3-3 be driven to push down on the activity in drill bit 1
Filling in 3-1 can all extrude the soil in drill bit 1, i.e., this completes a soil sample acquisition tasks；After unclamping hand lever 3-4,
Lever firming device 3 can rotate down under the rebound effect of torsional spring 3-5, until being restored to original position.It is reciprocal with this, until
Complete all sampling tasks.
One kind lever firming formula earth boring auger device provided by the invention and its application method have continued traditional Soil Sample dress
Set --- earth boring auger sample mode, but unlike to increase angle at the drill bit of lower end on the basis of original unique and sharp
Serrated edge, enable drill body quickly into soil stratification, accelerate sample rate, save unnecessary manpower and disappear
It consumes, also improve test efficiency, meanwhile, the blunt device of iron is added in handle upper end, the scope of application of the present apparatus is expanded and makes
Use the limit；But also the tradition method of tool slowly outside soil digging sample has been abandoned, it is added on the basis of original unique
Lever firming formula device greatly simplifies the complex process for taking out soil sample from drill bit, saves largely for field test
Valuable time, and its structure and principle are easily understood, are flexible to operation, specification is small, light-weight, do not interfere with earth boring auger
Normal use is a kind of sample acquisition machine of more satisfactoryization, has good value for applications.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
