Description
Technical field
The utility model is related to a kind of soil test device, more particularly to a kind of experiment of multifunctional earth to cut sampling device.
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, the soil that sampling device will be prepared usually is hit 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 each instrument manufacturer facility man produced at present 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 structure type 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 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, cause 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 cut by DC MOTOR CONTROL and filled
Put and move up and down, so that full-automatic sample preparation is realized, 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, may so 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 ensured during cutting other shapes sample by the native disc spins of DC MOTOR CONTROL incision
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
Treatment, 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 utility model provides a kind of multifunctional earth experiment and cuts sampling device.The utility model can be accurately controlled rotation
Speed, is easy to control to make the size of soil sample again, also can control cutting speed and lower knife point.Improve precision.Overcome hand
The inefficiency of dynamic cutting, precision shortcoming not high, while also overcoming forefathers' utility model unitary function, it is impossible to voluntarily judge
The deficiency of earth pillar medium stone.
The utility model include console, data wire, support, direct current generator, lower cutting soil disk, fixed pin, pressure sensor,
Upper cutting soil disk, mobile valve, bite and upper cutting soil disk connecting shaft, direct current generator are arranged on the table top of support, lower cutting soil disk with
The output shaft of direct current generator is fixed together, and the top of lower cutting soil disk has upper cutting soil disk, cuts above lower cutting soil disk and above soil
Fixed pin is fixed with below disk, the top of upper cutting soil disk is hinged with upper cutting soil disk connecting shaft, upper cutting soil disk with above cut soil
Disk connecting shaft can be relatively rotated, upper cutting soil disk connecting shaft through support upper beam slab, upper cutting soil disk connecting shaft by retainer plate and
Trip bolt is arranged on the upper beam slab of support；Upper beam slab offers bar hole, and bite is arranged in bar hole, on bite
Mobile valve is provided with, mobile valve can drive bite to be moved freely in bar hole, have pressure sensor, direct current on bite
Machine, pressure sensor and mobile valve are connected by data wire with console.
In operation, be placed in soil sample on lower cutting soil disk and be 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
Adjust the slewing rate of direct current generator and the movement locus of mobile valve.The utility model just can automatically carry out soil sample afterwards
Cutting.And reach demand.
The beneficial effects of the utility model：
1st, the velocity of rotation of lower cutting soil disk is controlled using direct current generator, and lower knife point and cutting speed is controlled by mobile valve
Degree.It is easy to operate, velocity of rotation can be both accurately controlled, it is easy to control to make the size of soil sample again, improve precision, it is to avoid
It is manual it is numerous and diverse with it is inconvenient, improve operating efficiency.
2nd, the utility model is engaged the whole sample making course of control with direct current generator using computer, so that produce
Sample needed for high-precision other soil tests is possibly realized.
3rd, the utility model may determine that the hard impurities such as the rubble in sample so that material is saved.
4th, the utility model uses 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.
