Embodiment
A kind of deep layer undisturbed soil sampler structure drawings and Examples that the utility model provides are described in detail as follows:
A kind of deep layer undisturbed soil soil sample barrel that the utility model provides, as shown in Figure 1, comprises connected successively handle 1, drilling rod 2, base 4, opposite opened sleeve pipe 5 and cutter head 6; Also comprise the shaft collar 3 that is enclosed within on drilling rod, be arranged on the cutting ring body (not shown) in opposite opened sleeve pipe 5, base, the circular sleeve cylinder consistent with cutter head composition external diameter.
The specific implementation of each parts and assembly relation as shown in Figure 2, are described in detail as follows:
The concrete structure of cutter head 6 as shown in Figure 2, cutter head entirety is hollow circular cylinder, hollow circuit cylinder leading portion knife-edge part adopts trisection vertical spin distribution sawtooth 61, and sawtooth becomes blade-like by root heavy wall to top thin-walled, the resistance can reduce to fetch earth time and the disturbance to soil sample; The rear end inwall of hollow circuit cylinder is provided with internal thread 62; Cutting ring body 7 is hollow core right cylinder, is coaxially placed in cutter head rear end, and cutter head internal diameter is identical with cutting ring body 7 internal diameters.
Opposite opened sleeve pipe 5, adopt two completely identical semi-circular tube close up into a circular sleeve, cutting ring body 7 is placed in circular sleeve, be convenient to take out built-in cutting ring body, circular sleeve internal diameter and cutting ring body 7 external diameters match, circular sleeve two ends are provided with external thread 51, two ends external thread 51 for the internal thread abutting joint of the end of cutter head and base; Base after installation, the circular sleeve cylinder consistent with cutter head composition external diameter.
As shown in Figure 2,3, it is shaped as the unlimited hollow circular cylinder in sealing one end, one end to base 4, and similar with cutter head shape, diameter is identical.The front inner wall that base is connected with opposite opened sleeve pipe 5 is provided with internal thread 41, and the other end is bottom 42, has air hole 421 on bottom, is convenient to fetch earth fast; The center of bottom is connected with a joint pin 43, and joint pin top is provided with a connection piece 8 (supplementing numbering 41 in Fig. 2, additional modifications numbering 4,42,421,43,8 in Fig. 3).Middle part is a columnar projections with connecting screw hole 431.
Shaft collar 3 is as shown in Fig. 1,4, by four fixed arms 33 (the present embodiment brachium 25-40cm) of right-angled intersection, one sleeve pipe 32 of the centre welding intersecting at four arms 33 forms (the present embodiment cover pipe range 25-35cm, depending on the difficulty that fetches earth), be provided with triangular form fixed claw 31 in each fixed arm bottom end; Casing pipe sleeve, on drilling rod, in cutter head inserts soil time, plays fixation, and the cutter head front end causing that rolls while preventing from fetching earth cuts open bad undisturbed soil, and has done rigid guarantee to vertically drilling through undisturbed soil;
As shown in Figure 1, drilling rod 2 is a hollow long rod, and two ends are provided with solid web member; The middle part of handle 1 is also provided with web member.
The web member of the present embodiment as shown in Figure 5, is made up of attachment cap 81, joint pin 82 and attachment screw 83, and attachment cap is hollow tube, and tube wall radially symmetry is opened two grooves 811, opens a connecting screw hole 812 with groove vertical direction; Joint pin is a solid cylinder, and length and the internal diameter of its length and diameter and attachment cap match, and joint pin has two orthogonal cylindrical protrusion 821, opens a connecting screw hole 822 with projection vertical direction.Corresponding with connecting screw hole 812 positions with the groove 811 of attachment cap respectively.
Web member one end of drilling rod is attachment cap structure, and the other end is joint pin structure, and the web member of handle and base is respectively attachment cap structure and joint pin structure, otherwise or.
As shown in Figure 2, shaft collar 3 is first enclosed within on drilling rod the concrete annexation of the each several part of the present embodiment, and two semi-circular tubes of opposite opened sleeve pipe 5 close up into a circular sleeve, and cutting ring body 7 is placed in opposite opened sleeve pipe 5; Then encircle handle and be connected by screw with the web member of drilling rod one end by web member, the web member of drilling rod 2 other ends is connected by screw with the web member of base 4; Base 4 is connected by screw thread with opposite opened sleeve pipe 5 respectively with cutter head 6.This structure ease of assembly of this soil sample barrel and dismounting, easy and simple to handle, efficiency is high.
The concrete size of each parts of the present utility model can be designed to multiple series, selects according to application actual conditions, and drilling rod can be designed to a fundamental length unit, as one one meter long, connect two or many according to application, long measure is carved with in outside, to precisely gather object degree of depth original-state soil.
An embodiment of this soil sample barrel is as follows:
The present embodiment, for drilling through the original-state soil of Wind-sandy Area deep layer 0-200cm, is 2m therefore choose drilling rod, is divided into 2, and every 1m, first installs 1m while drilling through, after first drilling rod bores down, second drilling rod is installed; Outside drilling rod, every 5cm graduates; Shaft collar brachium is chosen to be 35cm; Sleeve pipe designated length is 30cm; Cutting ring body is that volume is 100cm
3standard cutting ring; Rear base, the circular sleeve cylinder consistent with cutter head composition external diameter are installed.
The use procedure of the deep layer undisturbed soil soil sample barrel of this example:
1. select sampling on-the-spot: this soil sample barrel is preferably applied in the deep layer collection of farmland and sand, avoids the tree root of the large-scale vegetation such as arbor as far as possible, is not suitable for metalling soil collecting;
2. assemble soil sample barrel: cutting ring is placed in opposite opened semicanal, tightens cutter head and base, base and drilling rod are connected and be screwed, be inserted in holder, then handle and drilling rod are connected and be screwed;
3. collecting soil sample: use hand turning handle when collection, stop operating when the degree of depth just reaches cutter head to base length downwards, upwards extract soil sample barrel; If continuous acquisition pedotheque, fetches earth continuously with this soil sample barrel; If fetch earth, spacing is greater than 10cm, and suggestion is first bored into the object degree of depth with supporting earth boring auger, then carries out soil collecting;
4. pedotheque arranges: cutter head and base are backed out, broken into two with one's hands opposite opened semicanal, by cutting ring taking-up, flatten by classic method, cover cutting ring both sides, put into aluminium box and wait for corresponding test.
