The power resources of stroke power machine structure and revolving power mechanism are motor 1, are cut by a mechanical knob realization
It changes.
In the present embodiment, 0.5 meter of pole length is sampled, extension bar grows 1.0~1.5 meters.Take the soil of 1.5~2.0 meters of depths in underground
Earth, use process is as follows：
Before soil sampling, extension bar 7 is dismantled from sampler, liner 3 is packed into thief rod 2, thief rod 2 with it is dynamic
Power connecting shaft 5 is threadedly coupled (or being connected by quick coupling), as shown in Figure 2；
Soil sampler is pressed in and is waited on soil sampling position ground, selects power output mode for impact by mechanical knob
Formula is rotary,
The sampling head 4 of thief rod 2 is squeezed into soil to prescribed depth；
By the power output mode of selection by thief rod 2 to prescribed depth (0.5 meter) is entered, then reverse starting is electric
Machine takes out thief rod, unscrews screw thread or power opens quick plug, further take out liner 3, surface layer soil sample is outwelled；
It is again introduced into soil from original position of fetching earth, the soil of 0.5~1.0 meter of depth is taken out with same operating procedure,
Fall；
When taking the soil sample of 1.0~1.5 meters of depths, original sampling pole length is inadequate, and 1.0 meters long of extension bar 7 may be selected, will
It is installed on by screw thread or quick coupling between power connection shaft 5 and thief rod 2；
Sampler is placed in the hole that former sampling leaves again, starts power plant and be deep into 1.0~1.5 meters of positions,
It takes out, soil is outwelled；
Last time by abovementioned steps operation, is deep into down in 1.5~2.0 meters of soil layer, the soil of taking-up is into fashionable
The soil sample to be taken.
Liner is made of materials such as plastics, not will produce metal residual in entering soil course, is effectively reduced soil
The interference of metallic element in sample.
Since there are the gaps less than 1mm between liner and thief rod, liner can be easily taken out, friction is reduced, to subtract
Small sampling resistance.
Again since thief rod top is equipped with first exhaust relief hole 1, extension rod is equipped with and extracts via hole, sampler enters
When soil layer, the air inside sampler can be excluded, reduce pressure.Via hole 8 is extracted simultaneously and wears a steel pipe, for assisting
Extract sampler.
In addition, extension bar can be arranged it is multiple, a length of 1.0~2.5 meters, can according to sampling depth select use.When sampling is deep
When degree is more than the sum of the length of a thief rod and an extension bar, it is possible to use two extension bars are connected in series, and realize deeper
The sampling of soil layer.
