It is not limited to the three state of above-mentioned displaying.
As shown from the above technical solution, a kind of testing equipment of incompact-deposit bodies meso-scopic structure analysis, main function
It is as follows:
(1) incompact-deposit bodies being suitable in rolling topography region: sampling tube end uses and landform inclination angle is consistent inclines
Inclined tube mouth, and sampling pipe nozzle inclined direction and tube length are determined by experimental design needs, meet rolling topography area with this
The requirement that bulk solid samples in domain.
(2) to incompact-deposit bodies spot sampling: can be pinpointed by sampled point control device for different incompact-deposit bodies
The loose media sample of key position point is chosen, and then provides basic data for the fining of packed structures analysis.
(3) intuitively show incompact-deposit bodies microscopical structure: sampling pipe is per se with scale, and scale size can be according to test
Size grading is selected, in this regard, the vertical microscopical structure of accumulation body can directly be presented on test at some point extracted
In face of person, and recorded using technologies such as camera shootings, while can also further be analysed in depth by electron microscopy.
(4) size grading of Accurate Analysis incompact-deposit bodies: after the directly analysis for completing incompact-deposit bodies microscopical structure,
The loose media in sampling pipe can be divided into height several pieces by control sampling pipe pipe envelope, then to it is every it is a respectively into
Row sieve analysis analyses in depth each key point of incompact-deposit bodies in the vertical size grading regularity of distribution with this.
The main innovation point of the utility model include: sampling point position is freely adjustable, sampling pipe pipe end can with rise
Shape of throwing oneself on the ground fitting, sampling nozzle can effectively close, sampling pipe can be convenient for loading and unloading, it is specific as follows:
(1) sampling point position is freely adjustable, for the accumulation body of different shape, the sampled point of testing crew concern
It is different, it is therefore desirable to which that sampling pipe connecting rod pulley and being used cooperatively for attachment device leading block in sampled point control device are realized
Level moves freely, in the utility model between magnetite and iron frame with stronger suction, it can be achieved that sampled point it is effective
It is fixedly connected while realizing and move freely；
(2) sampling pipe pipe end can be bonded with rolling topography, and for the accumulation body in different topographies, sampled point may not
For level ground, it is therefore desirable to which sampling pipe carries out special customized, sheet according to sampled point angle of slope of ground degree and inclined direction
Sampling pipe in utility model can be customized according to actually required length, inclination angle and inclined direction, to meet sampled point fluctuating
The specific demand of landform guarantees the leakproofness of sampling pipe port；
(3) sampling nozzle can be closed effectively, since friction is small between loose media and sampling pipe side wall, need to have adopted
Effective sealing treatment is carried out after sample, and pipe is sealed in sampling apparatus and is set as identical as sampling pipe inclination angle, avoids pine as far as possible
Granular media excessively leaks out, and is then fastened using a plurality of strength rubber band；
(4) sampling pipe can be convenient for loading and unloading, and sampling pipe can integrally be inserted into when being inserted into and also be inserted separately into, after the completion of final sampling
It can integrally lift and also individually lift, therefore it is required that can be convenient for assembly with disassembly between sampling pipe and attachment device, this is practical new
It is using 2 pairs of perforated screws that sampling pipe is effectively fixed and convenient for loading and unloading in type.
