Abstract
The invention relates to an in situ non-destructive soil sampler which includes a cylinder drill 1, a drill rod 2, a handle 3, an inner ring 4, an inner ring support 5 and an inner push rod 6, and is characterized in that the front end of the cylinder drill 1 is provided with an elastic cutting edge with bayonet; the cylinder drill 1 and the drill rod 2 are welded together; the drill rod has a hollow pipe-like structure; the inner push rod 6 and the inner ring support 5 are welded together; the inner push rod and the inner ring support are installed in the sleeves of the drill rod 2 and the cylinder drill 1; the inner ring 4 is installed in the sleeve of the cylinder drill 1; the inner push rod 6 pushes the inner ring support 5 to move axially, so as to push the inner ring 4 fully filled with original soil out of the cylinder drill. The sampler has the advantages of simple structure, convenience in operation, economy and practicality.
Description
Technical field
The invention belongs to a kind of soil sampling apparatus, obtained soil sample can be used to measure soil volume proportion, soil volume proportion can be used to calculate parameters such as the weight of certain area certain depth soil and soil porosity, utilizes this device can get the undisturbed soil sample of different depth.
Background technology
For measured soil unit weight exactly, relatively classical ground method is with 100cm
3Steel cutting ring (edge of a knife end is downward) steadily be pressed in the soil, after earth pillar is emerged cutting ring upper end, dig surrounding soil with spades, taking-up is full of the cutting ring of soil, if measure the deeper soil weight, then to excavate soil profile, excavating depth often reaches 1m or darker.For anthropogenic soil, so hard intensity ground disturbed soil is got the undisturbed soil sample, can only be limited in spring and autumn.Yet the many farming operations (as middle tilling depth pine, irrigation or the like) during the crop growth are very dark to the influence of the soil weight, situation as untimely these variations of grasp, be difficult to propose scientific and effective regulation measure, and traditional sampling method wastes time and energy, effect is very low.Therefore on the basis of traditional core cutter method, studying a kind of original position, not have the destructive utensil that successively drills through undisturbed soil be very necessary.
Summary of the invention
The purpose of this invention is to provide a kind of in-situ non-destructive soil sample collector, use this sampler to avoid the large tracts of land disturbed soil, successively drill through undisturbed soil, overcome the restriction in season and place, reach and drill through the undisturbed soil sample whenever and wherever possible, in time grasp the plant growth soil weight dynamic change in each period, for the science regulation and control provide data.
The object of the present invention is achieved like this: this sampler is under the situation of disturbed soil not, utilizes the mode layering of drilling to drill through undisturbed soil.It comprises a brill, drilling rod, handle, interior ring, interior ring holder and inner push-rod, it is characterized in that: tube bores and is the barrel-like structure of hollow, the cutting edge of its front end partly is the large semicircle cylinder, vacate the bayonet socket of part for ring in installing, the cutting edge face of cylinder and tube bore between the body cylindrical face and have breach, and the cutting edge of barbed portion is bored interior curve formation elasticity cutting edge to tube; Tube bore to connect the drilling rod of hollow tubular, ring holder in inner push-rod connects, interior ring holder be movably arranged on axially together with inner push-rod that tube bores and drilling rod in, interior ring is the cylindrical drum structure of thin-walled, interior ring is installed in the tube brill.
Above-mentioned bayonet socket size L
1Internal diameter Φ than the tube brill
1Little 1mm-2mm, the span of cut height h is 1mm-2mm, the span of notch length L is 16mm-22mm, elasticity cutting edge height h
1Span be 8mm-12mm; Tube bores height H, interior ring height H
1, interior ring holder height H
2, elasticity cutting edge height h
1, a tube pass of boring between the wall thickness t is: (H
1+ H
2) greater than (H-h
1-t) 2mm-3mm.
Advantage of the present invention is: the elasticity cutting edge of tube brill front end is designed to have the structure of bayonet socket, this structure is under having guaranteed the prerequisite of encircling in fixing, the interior ring tube of packing into is smoothly bored, reduced the contact area of tube drill lip mouth and soil simultaneously, reduce the friction force of soil and cutting edge, more help drilling through of undisturbed soil.Avoid the large tracts of land disturbed soil in the process that fetches earth, drill through the undisturbed soil sample whenever and wherever possible, simultaneously simple in structure, low cost of manufacture, easy to operate, be easy to carry.

Fig. 2 is that tube brill structure master looks synoptic diagram.
Fig. 3 is that the tube brill is overlooked enlarged drawing.
Embodiment
General structure synoptic diagram of the present invention as shown in Figure 1, the material of all parts is a stainless steel, it comprises, and tube bores 1, drilling rod 2, handle 3, interior ring 4, interior ring holder 5 and inner push-rod 6.It is the barrel-like structure of hollow that tube bores 1, and its front end is the elasticity cutting edge 8 that bayonet socket 7 is arranged, and tube brill 1 is welded as a whole with drilling rod 2, and drilling rod 2 is a hollow tubular structure; Inner push-rod 6 and interior ring holder 5 are welded as a whole, and interior ring holder 5 is installed in together with inner push-rod 6 in the sleeve of tube brill 1 and drilling rod 2, and interior ring holder 5 is clearance fit with tube brill 1, inner push-rod 6 with drilling rod 2, so that axial movable; Interior ring 4 is the cylindrical drum structure of thin-walled, and interior ring 4 is installed in the sleeve of tube brill 1, and the two is a clearance fit, so that axially activity.Drilling-rod external wall is carved with scale, is convenient to accurately drill through the undisturbed soil sample of different depth.
As shown in Figures 2 and 3, cutting edge 8 parts that tube bores 1 front end are the large semicircle cylinder, vacate the bayonet socket 7 of part for ring 4 in installing, the cutting edge face of cylinder and tube bore between the body cylindrical face and have breach 9, and the cutting edge 8 of breach 9 parts bored interior curve to tube, purpose is to form the elasticity cutting edge, utilizes elasticity cutting edge stationary magazine creel to bore 1 interior interior ring 4.During design, the span of breach 9 size L is 16mm-22mm, and the span of cut height h is 1mm-2mm, cutting edge height h
