Description
Technical field
The present invention relates to a kind of soil test device, more particularly to sampling device is cut in a kind of test of multifunctional earth.
Background technology
At present in the preparation process of the original-pack soil sample of soil test, sample device is cut only for preparation ordinary triaxial test,
And others such as between test used cylindrical soil sample, the rectangle sample in true triaxial experiment etc. but special
Instrument carries out the preparation of sample.For disturbed soil, usually sampling device is hit by the soil for preparing using supporting with instrument
Sample hits reality by predetermined dry density layering, is then directly installed on test base, is tested.And for the system of undisturbed soil sample
It is standby, it is general that native device is cut by soil sample cutting forming using supporting with test apparatus.What at present each instrument manufacturer facility man produced cuts
In addition to fixed frame has some differences, the part that it is used to place and fix soil sample is essentially identical, all for the version of native disk
It is to be respectively mounted a disk that can be rotated up and down in fixed frame, soil sample is placed on into folder in the middle of two disks during sample preparation
Tightly, fixed soil sample disk is then constantly rotated, and cutwork is carried out with native knife or fret saw is cut.It is done so that can be due to
Manual cutting causes cutting not enough precisely, causes experiment error occur, and because lower cutting soil disk is circular, causes manual cutting
Earth pillar beyond cylinder is almost impossible.And manual cutting is wasted time and energy, efficiency is too low.Chinese patent CN102169062
Disclose it is a kind of cut sample instrument for prepare triaxial test intact loess sample, the patent is filled by DC MOTOR CONTROL cutting
Put and move up and down, so as to realize full-automatic sample preparation, but the patent can only prepare the sample used by single triaxial test, general use
Property is not strong, and the patent cannot judge the object of the crushed stone in cutting process in earth pillar, so may cause to sample
Catastrophic collapse, so as to waste earth material.2 points for more than, Chinese patent CN205103074 discloses a kind of geotechnique's examination
Test and cut sample device with multi-functional.The patent is guaranteed when cutting other shapes sample by DC MOTOR CONTROL incision soil disc spins
Lower knife accuracy, and due to being automanual artificial cutting, it is possible to which ensureing to encounter stone in working angles can be timely
Process, it is to avoid waste.But the patent also has weak point.Firstly, since being semi-automatic cutting, then just inevitably
There is the uneven situation of cutting, and manual cutting is wasted time and energy, and efficiency is excessively low.There is significant limitation.
The content of the invention
The present invention provides a kind of multifunctional earth test and cuts sampling device.The present invention can be accurately controlled velocity of rotation, and
It is easy to the size for controlling that soil sample need to be made, also can control cutting speed and lower knife point.Improve precision.Overcome manual cutting
Inefficiency, the not high shortcoming of precision, while also overcoming forefathers' invention single function, it is impossible to voluntarily judge earth pillar medium stone
It is not enough.
The present invention include console, data wire, support, direct current generator, lower cutting soil disk, fixed pin, pressure sensor, on cut
Native disk, mobile valve, bite and upper cutting soil disk connecting shaft, direct current generator is arranged on the table top of support, lower cutting soil disk and direct current
The output shaft of motor is fixed together, and the top of lower cutting soil disk has upper cutting soil disk, above lower cutting soil disk and under upper cutting soil disk
Face is fixed with fixed pin, and the top of upper cutting soil disk is hinged with upper cutting soil disk connecting shaft, and upper cutting soil disk connects with upper cutting soil disk
Spindle can be relatively rotated, and, through the upper beam slab of support, upper cutting soil disk connecting shaft is by retainer plate and fastening for upper cutting soil disk connecting shaft
Screw is arranged on the upper beam slab of support；Upper beam slab offers bar hole, and bite is arranged in bar hole, and bite is provided with
Mobile valve, mobile valve can drive bite to move freely in bar hole, with pressure sensor on bite, direct current generator,
Pressure sensor and mobile valve are connected by data wire with console.
In operation, soil sample is placed on lower cutting soil disk and is absorbed in solid by cutting soil disk connecting shaft in appropriate height in adjustment
Determining pin fixes it, then adjusts cutting soil disk connecting shaft in appropriate height, cutting soil disk is contacted with soil sample.Operating console
The movement locus of the slewing rate of adjustment direct current generator and mobile valve.Afterwards the present invention just can automatically carry out cutting for soil sample
Cut.And reach demand.
Beneficial effects of the present invention：
1st, the velocity of rotation of lower cutting soil disk is controlled using direct current generator, and by the lower knife point of mobile valve control and cutting speed
Degree.It is easy to operate, velocity of rotation can be both accurately controlled, the size for controlling that soil sample need to be made is easy to again, improve precision, it is to avoid
It is manual it is numerous and diverse with it is inconvenient, improve operating efficiency.
2nd, the present invention is engaged the whole sample making course of control with direct current generator using computer, so that produce high-precision
Sample needed for other soil tests of degree is possibly realized.
3rd, the present invention may determine that the hard impurities such as the rubble in sample so that material is saved.
4th, the present invention adopts vertical cutting way, reduces disturbance of the working angles to soil sample.
5th, it is easy to operate, only sample need to be put into device, manipulate console.
