Embodiment
The foot-operated compressed soil-sampling tool of one as depicted in figs. 1 and 2, comprises handle 1; Described handle 1 lower end is vertically welded with drilling rod 2; Described drilling rod 2 movable sleeves are connected to upper footboard 3, and bottom is fixed with lower pedal 4; On described drilling rod, be also movably installed with positioning convex ring 8; Described upper footboard 3 and lower pedal 4 middle parts are respectively arranged with the first through hole (not shown) and the second through hole (not shown); Described the first through hole (not shown) inside is provided with screw thread (not shown); Described lower pedal 4 lower ends are fixedly connected with drill bit 5; Described drill bit 5 internal activities are provided with firming plate 6; Described firming plate 6 upper ends are welded with connecting link 7; Described connecting link 7 is connected by screw thread (not shown) and upper footboard 3 through the first through hole (not shown) and the second through hole (not shown).
Wherein, described handle 1 is made up of hollow tubular; Described drilling rod 2 is symmetrically arranged with two, and is provided with scale 9; Described positioning convex ring 8 is provided with two; Described drill bit 5 is cylindric, and bottom is provided with cutting edge; Described connecting link 7 is solid hopkinson bar, and top is provided with screw thread (not shown), and matches with the internal whorl of upper footboard 3; Said structure is made by stainless steel material except positioning convex ring.
In the time fetching earth, pin firmly pushes down on the pedal 4, drill bit 5 can go deep into soil, connecting link 7 rises along with the rising of earth pillar together with firming plate 6, in the time that earth pillar reaches certain height, drill bit is vertically extracted from soil, by tightening the screw thread (not shown) on screw thread (not shown) and the upper footboard 3 on connecting link 7, then allow positioning convex ring 8 navigate on required scale 9, if existing earth pillar height is higher than required depth of soil, tramp with one's feet pedal 3 depress to positioning convex ring 8 places, can release unnecessary earth pillar, continue to push away the soil sample that obtains desired depth, if existing earth pillar height is lower than desired height, need drill bit 5 to relay the former state that fetches earth of getting back to, slamming lower pedal 4 continues to fetch earth, until obtain the earth pillar of desired depth.
The length of above-mentioned connecting link 7 equals the maximum length of drill bit 5.
Above-mentioned scale 9 is up marked along drilling rod by the foot of two drilling rods 2, and maximum scale value equates with drill bit 5 maximum lengths, and scale value correspondence the degree of depth of the corresponding soil layer of the interior earth pillar of drill bit 5 like this, facilitates layering to fetch earth.
Above-mentioned positioning convex ring 8 arbitrarily moves up and down on drilling rod 2, can be according to requirement of experiment need to navigate to a certain scale.
Above-mentioned drill bit 5 bottom is equipped with sharp cutting edge in one week, makes geotome easier when going deep in soil.
Said structure processes by stainless steel material except positioning convex ring 8, and quality is hard, avoids getting rusty, and the life-span is long, because smooth surface reduces the frictional resistance bringing between brill itself and soil, and lightweight, easy to carry.
The utility model is a kind of foot-operated compressed soil-sampling tool of simple in structure, fetch earth convenient and complete function; Because the utility model employing is foot-operated, can by auxiliary strength such as external force, drill bit be goed deep into soil and earth pillar be released, it is time saving and energy saving really to accomplish; Earth pillar retains complete in drill bit, and what after releasing, obtain is soil column; Firming plate adopts and is threaded with upper footboard, for convenience detach, can accomplish timely cleaning, in case the mutual mixing between sample after taking a sample; Positioning convex ring can, according to requirement of experiment, be adjusted position at any time, and intuitively reads the required earth pillar degree of depth by scale, and go up pedal by control, meet experimentally the degree of depth requirement accurately of fetching earth, played the effect of getting twice the result with half the effort, greatly improved work efficiency.The utility model is simple and reasonable, with low cost, and result of use is very good.
Embodiment recited above is described preferred implementation of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of the utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents of the utility model request protection, has all been documented in claims.
