Abstract
The utility model relates to a portable manually-operated sample preparation instrument comprising an upper handle, a lower handle, an inner lead screw and an outer lead screw, wherein one end of the outer lead screw is fixed with a guide groove while the other end thereof is connected with the lower handle; the an inner lead screw is sleeved in the outer lead screw; a magnetic piston core is mounted at the top end of the inner lead screw in the same direction with the outer lead screw; the piston core does piston motion inside the guide groove; the guide groove takes a hollow form and is sealed with the connecting end of the outer lead screw, the other end thereof adopts an open end, and a cutting ring is mounted at the opening end; and the magnetic piston core absorbs the cutting ring. The utility model has the advantages of small volume, portability, high performance price ratio, and simple and convenient operation, use and maintenance after use, and can be widely applied to geotechnical engineering scientific researches, teaching practices and productive filed, so as to meet the needs of sample preparation when physical mechanic indexes are determined during geotechnical engineering tests.
Description
Technical field
The utility model relates to a kind of portable manual sampling instrument, belongs to geotechnological sample preparation instrument.
Background technology
Present geotechnological sample preparation instrument is mainly used in the actual earthwork engineering, its complex structure, and volume is big, is not easy to carry, and in use complicated operation is not easy to use in scientific research, teaching and test.
Summary of the invention
The utility model purpose just is to provide a kind of convenient portable manual sampling instrument that uses, and this portable manual sampling instrument comprises upper and lower handle and inside and outside lead screw at least, and an end of outside nut bar is fixed with gathering sill, and the other end is connected with lower handle; Be with the inside screw bar in the outside nut bar, the piston core with magnetic is equipped with on inside screw bar and outside nut bar top in the same way, and piston core is done the piston motion in gathering sill, gathering sill is hollow form, seal with outside nut bar link, the other end is the opening shape, and openend is equipped with cutting ring.The magnetic piston core has attracted cutting ring.
Between the openend of cutting ring and gathering sill by being threaded.
The outside nut bar is fixed on the base by support.Be provided with the adjustable and balancing screw below the base, screw is along four jiaos of symmetrical distributions of base.Be positioned at gathering sill vertical lower place on the base and be provided with built-in reflective mirror, be used for observing the preparation situation of soil sample.
The utility model adopts armstrong's patent control, to replace the traditional-handwork operating type.This instrument can be handled the scleroid preparation of soil sample, also can solve the specimen preparation of manipulated soil, is a kind of quick and dynamical sample preparation utensil, can reduce because of the traditional-handwork method of operating, and to the man's activity of sample generation, thereby the preparation merit that improves sample is planted.Can be widely used in Geotechnical Engineering scientific research, teaching practice and productivity field, to satisfy the needs that prepare test specimen when mechanics index of physics is measured in the Geotechnical Engineering test.
The utility model volume is little, can carry, and cost performance is low, manipulates with simple and convenient with the back maintenance.

Embodiment
A kind of portable manual sampling instrument which comprises at least upper handle 1, lower handle 2 and inside screw bar 3, outside nut bar 4, and the 4-end of outside nut bar is fixed with gathering sill 6, and the other end is connected with lower handle 2; Be with inside screw bar 3 in the outside nut bar 4, inside screw bar 3 is equipped with the piston core 5 with magnetic with outside nut bar 4 top in the same way, piston core 5 is done the piston motion in gathering sill 6, gathering sill 6 is hollow form, seal with outside nut bar 4 links, the other end is the opening shape, openend is equipped with between the openend of cutting ring 10. cutting rings 10 and gathering sill 6 and is connected by screw thread 11. and outside nut bar 4 is fixed on the base 8 by support 7. be provided with the adjustable and balancing screw below the base 8, screw is along four jiaos of symmetrical distributions of base. and the base that is positioned at the gathering sill vertical lower is provided with built-in reflective mirror 9, is used for observing the preparation situation of soil sample.
Upper and lower handle is the cylinder body rod, and diameter is 1.5cm.Wherein, the long 8cm of upper handle, the long 12cm of lower handle.Inside screw bar 3 long 12cm, diameter is 3cm; Outside nut bar 4 long 15cm, diameter is 3.6cm.The guiding flute length is 10cm, and its overall diameter is 7.2cm, and interior diameter is 6.2cm; The cutting ring height is 2cm, and it is down with the inside edge of a knife.
Left and right sides two parts of support are symmetrical in base, and are connected in entablature in the upper end.The support height is 30cm, and diameter is 3cm, and crossbeam is a strip metal iron plate, and long is 15cm, and wide is 8cm.
This sampling instrument volume is little, can carry, and the cost performance height, its using method is as follows:
1. instrument is placed on the experimental work table top, adjusts the balance screw of base, makes it to keep horizontality.
2. the soil sample with the desire preparation is placed on the base.
3. turning handle (use upper and lower handle to select, should look soft, the hard degree of soil sample).
4. gathering sill is passed downwards under the effect of turning handle gradually, and cutting ring begins to prepare soil sample in it.
5. with hand steered firmly gathering sill, the cutting ring of releasing is separated with gathering sill, gathering sill upwards rotates mentions, and with cutting native cutter crosscut cutting ring soil face, makes it the moulding of cutting ring soil sample then.
6. after instrument was used to complete, the wiping drying of keeping a public place clean was smeared rust preventive oil.
Claims (5)
