Abstract
The invention discloses an automatic soil test sampling machine and a sampling method. The method comprises the following steps: putting the materials into a funnel, putting the materials into a material discharge groove from the funnel, and weighing by adopting an electronic scale; shaking the material into a soil sample mold by a vibration exciter; the telescopic rotating rod drives the compactor to carry out rotary compaction on the materials in the soil sample mold to an appointed height; the flexible rotating rod pushes the broom head to rotate in the soil sample mould for broom. The invention not only effectively reduces the uneven distribution degree of soil on each layer during sample preparation, reduces the uneven distribution degree of layers, but also overcomes the phenomenon of axial deviation in real time during sample preparation pressure and the phenomenon of excessive smashing or less smashing during sample smashing and compacting. Effectively improved the appearance quality of soil sample, effectual improvement work efficiency and reduced working cost, the appearance of making accords with geotechnical test's requirement.
Description
Technical field
The present invention relates to a kind of automatic soil test sampling machine and method for making sample, belong to soil test soil sample manufacture technology field.
Background technology
At present, in a lot of building class scientific research institutions the hollow cylinder torsional shear instrument is arranged, triaxial apparatus, Resonant Column need to be reinvented into the various character that sample is studied soil with soil.Can geotechnological experimental data be extremely important accurately for making for the one-tenth sample quality of soil.Therefore, the factor that has been made into a key that can make success of the test of soil sample.
The sample preparation of reinventing of nowadays most of soil tests substantially all is manual sample preparation, and manually sample preparation takes time and effort, and the soil sample possibility difference of different people's systems is very large, and the soil sample of doing when same person is different may quality also have very large difference.And manually there are a lot of lack of standardization or inevitable technological deficiencies in the sample preparation.For example, sample preparation all can layering be put earth material, supposes minute four layers of placement, during blowing because manually, the distribution during unavoidable every layer of blowing native inhomogeneous, the excessive phenomenon of local quality appearred in soil sample when this just caused compacting, caused the undesirable of experimental data.Owing to the hand steered sample device of pounding, position, disalignment in the time of can occurring pounding sample unavoidably causes the local packing difference of soil sample very large in pounding the sample process.Because power control is accurate not, the phenomenon of pounding or pounding less can occur when manually pounding sample, pound if cross, soil sample will be made again so, lose time and muscle power.In the middle of the between the layers brooming process, usually also occur to be connected inhomogeneous phenomenon, so that in process of the test, cause the undesirable or test failure of data.Coming sample preparation even nowadays have with sampling machine, also is that automaticity is very low, be mingled with a lot of manpowers, and sample making apparatus can only make certain soil, certain big or small soil sample.
In order to improve the quality of sample preparation, increase work efficiency, reduce labour cost and labour intensity, in the urgent need to the sample preparation instrument of science, robotization.But nowadays domestic not yet have a this robotization sample preparation instrument.
Summary of the invention
The present invention seeks to provides a kind of automatic soil test sampling machine and method for making sample for the defective that prior art exists, the present invention is scientific and reasonable, and the sampling machine that automaticity is higher is applicable to multiple soil, the sample preparation demand of sizes soil sample, and instrument is simple to operation.
The present invention adopts following technical scheme for achieving the above object:
A kind of automatic soil test sampling machine of the present invention, it is characterized in that comprising compactor, hair-sweeping device, expansion bend, rotating disk, vibrator, funnel, the soil sample mould, rotary base, support, trough and mold base, wherein expansion bend is arranged at support top, compactor and hair-sweeping device are connected with expansion bend by flexible dwang respectively, rotary base arranges frame bottom, the top of rotary base arranges rotating disk, the soil sample mould is arranged at rotating disk top by mold base, the setting corresponding to the soil sample mould of one end of trough, the other end of trough is corresponding with the discharging opening of funnel to arrange and arranges vibrator; Vibrator is trembled the original mold tool that buries with the material in the funnel by trough, and expansion bend is pushed into compactor or hair-sweeping device directly over the soil sample mould, drives compactor or hair-sweeping device is rotated compacting or rotates brooming by flexible dwang.
Hopper valve switch and electronic scale also are set on the described funnel.
Described compactor is solid compactor or hollow compactor.
Described hair-sweeping device is solid hair-sweeping device or hollow hair-sweeping device.
A kind of method for making sample of automatic soil test sampling machine is as follows:
Material is put into funnel, open the hopper valve switch, material is put into trough by funnel, hopper valve autoshutdown when adopting electronic scales meter heavy burder to reach default weight; By vibrator material is trembled the original mold tool that buries; By expansion bend compactor is pushed into directly over the soil sample mould, drives compactor by flexible dwang and the material in the soil sample mould is rotated is densified to specified altitude assignment; Reintroduce compactor, by expansion bend hair-sweeping device is pushed into directly over the soil sample mould, promote hair-sweeping device by flexible dwang and to the soil sample mould, rotate brooming, then propose hair-sweeping device.
Advantage of the present invention and effect are:
1. because the scalable random length of controllable extensible dwang, therefore be not limited to the number of plies of layering during sample preparation, can divide infinite layers in theory, can make so between layers as far as possible evenly, because in the jolt ramming process spinfunction is arranged, the soil body is evenly distributed in every layer of distribution again.
2. owing to the controllability of controllable extensible dwang, having avoided pounding sample is that phenomenon is pounded or pounded less to the mistake that occurs.
3. owing to can divide many times blowing during every layer of blowing, be not limited to equally the blowing number of times, mold bottom has rotating disk can set the number of revolutions that turns around according to the number of times of blowing equally, and is even as much as possible during every layer of blowing of assurance.
4. because compactor and hair-sweeping device perpendicular to mould, have therefore overcome the phenomenon that off-axis occurs in the process of compacting or brooming.
5. because the replaceability of compactor, hair-sweeping device and mould is not limited to the soil sample of making a type, only need change different models, can make the soil sample of different model, save like this space and cost of manufacture.
6. owing to the setting of hair-sweeping device, the layer that has occurred when effectively having solved the layering sample preparation and layer be the problem of loose contact effectively.
