Description

A kind of soil constant volume sampler
Technical field
The utility model is specifically related to a kind of soil constant volume sampler, belongs to soil sampling technical field of tools.
Background technique
In agricultural production and environmental survey, the pedotheque of different soil depth is often acquired, it is related to carry out soil Analysis of physical and chemical property etc., when analyzing the soil weight, the measurement of the soil weight needs the undisturbed soil of normal volume to carry out Analysis, usual measurement method mostly use core cutter method, the good soil profile point of Samples selecting in field, excavate soil profile and by soil Earth occurs level and steadily squeezes into cutting ring at each soil genetic horizon time middle part from bottom to top, after cutting ring fully enters soil, uses Spade cuts out the soil around cutting ring, takes out cutting ring, it is careful deviate from cutting ring upper end cutting ring support, then scabble cutting ring with cutting native knife The soil at both ends, so that soil volume is certain in cutting ring.It is time-consuming and laborious due to excavating soil profile, surface soil structure is destroyed Greatly, often sampled point is more in real work or microcell location test does not allow to excavate section, and researching and designing goes out one kind thus Can original state take soil soil constant volume sampler, for reduce labor intensity, improve working efficiency have important application value.
Summary of the invention
In view of the above-mentioned drawbacks of the prior art, the utility model provides a kind of undisturbed soil soil constant-volume sampling tool. It, can be by pedal or hammer mode by sampling drill its main feature is that hand-held, soil sampling cutting ring is built in core cutter Soil depth needed for head is pressed into realizes that undisturbed soil constant volume acquires soil sample.
Specifically, a kind of soil constant volume sampler of the utility model, including upper coupling part, connecting pin, core cutter Side cover, core cutter, roach ring, cutting ring, jackscrew, the upper coupling part include handle, pedal, connecting tube, top anvil, it is described on By connection pin connection, the core cutter inner cavity is semi-circular cylindrical, interior to be sequentially placed into equipped with boss for coupling part and sampling head Roach ring, cutting ring, roach ring, the core cutter side cover and core cutter are fixed with jackscrew and are integrated.
Further, the main part of the upper coupling part is welded with seamless steel pipe, the top anvil of upper coupling part It is process for circular bar, Entire nickel coating.
Further, the core cutter is that nickel plating high-strength steel is process, and core cutter side wall center is equipped with circle Hole, core cutter bottom end are equipped with conical rings edge, and top is equipped with the upper end cover of full-circle spray pattern, and end cap is equipped with top wire hole, and The connection pin shaft of aperture is equipped in end cap central position.
The utility model has the beneficial effects that: may be implemented in the case where not excavating soil profile, it can be by different level Accurate realization soil constant volume sampling, structure is simple, and it is convenient to dismantle, and can carry out the soil sampling work of next point after taking out cutting ring Make, work efficiency is high, and labor intensity is effectively reduced.

In figure: on 1 coupling part, 2 connecting pins, 3 core cutter side covers, 4 roach rings, 5 cutting rings, 6 core cutters, 7 jackscrews, 8 handles, 9 connecting tubes, 10 top anvils, 11 pedals, 12 pin shaft connecting holes, 13 connection pin shafts, 14 upper end covers, 15 circular holes, 16 circular cones Shape cutting ring cutting edge, 17 top wire holes.
Specific embodiment
Specific embodiment of the present utility model is illustrated with reference to the accompanying drawing, it is existing it is an object of the invention to overcome There are the shortcomings that technology and deficiency, a kind of soil constant volume sampler is provided, structure is simple, work efficiency is high, it is strong that labour is effectively reduced Degree.
As shown in Fig. 1 to Fig. 7, the present invention uses design for disassembly, and coupling part 1 and core cutter 6 pass through on sampler Connecting pin 2 is connected and fixed, and is successively placed in roach ring 4 in core cutter 6, cutting ring 5, roach ring 4, core cutter side cover 3 with adopt Sample drill bit 6 is integrated with the fixation of jackscrew 7.
Coupling part 1 on sample acquisition machine shown in Fig. 3, including handle 8, connecting tube 9, pedal 11, top anvil 10, in connecting tube 9 are equipped with pin shaft connecting hole 12, and wherein handle 8, connecting tube 9 and 11 material of pedal are seamless steel pipe, and top anvil 10 is using round Bar processing is coniform, and effect is to bear hammering stress, and the effect of pedal 11 is to provide double-legged pedal, double convenient for operator Foot, which is integrally had an effect, makes sampler be easier to go deep into soil, and labor intensity is effectively reduced, and all component integral solders are integral, whole Nickel plating.
Core cutter 6 shown in Fig. 5 are process using nickel plating high strength steel, and side wall center is equipped with circular hole 15, bottom end Equipped with conical rings edge 16, upper end is equipped with the upper end cover 14 of full circle, and upper end cover 14 is equipped with top wire hole 17, and in upper end cover 14 centers are equipped with the connection pin shaft 13 of aperture.
Fig. 6 show core cutter side cover 3, and the 3 side wall center of core cutter side cover is equipped with circular hole, and upper end is equipped with Semicircle shape end cap, and top wire hole is equipped on end cap.
Shown in Fig. 7 is roach ring, and when sampling is placed in cutting ring both ends, one end one, and effect is to make cutting ring full of original Shape soil, the soil for facilitating cutting ring both ends of the surface are neatly cut.
The working process of the utility model is as follows: soil sampling place is chosen, core cutter 6 is aligned by both hands gripping handles 8 Above soil to be sampled, first passes through both hands and apply certain pressure by core cutter 6 into certain soil depth, according to soil reality Situation, selection keep core cutter native completely into arriving by means of bilateral pedal 11, by the strength of kicking of body wt and both legs In earth or the mode hammered is selected, then rotating handle 8, firmly propose core cutter 6, at this time full of soil in core cutter 6 Sample unscrews jackscrew 7, unloads core cutter side cover 3, takes out cutting ring 5, has been filled with continuous cylinder shape constant volume soil column in cutting ring 5, With the soil for cutting native knife and scabbling cutting ring both ends, so that soil volume is certain in cutting ring, packaged cutting ring, which marks, completes one A depth level soil sampling work, carries out cleaning work, can carry out the work of next sampled point.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art For personnel, under the premise of not departing from principle described in the utility model, it can also make several improvements and retouch, these improvement It also should be regarded as the protection scope of the utility model with retouching.
