The utility model relates to a kind of soil investigation utility appliance, especially relates to the multi-level cutting ring formula of a kind of many soil properties and to fetch earth earth boring auger.Comprise cutting ring, drill bit, drill body, handle and auxiliary hammer, handle is connected with drill body by the first connector, and drill body is connected with drill bit by the second connector, screw thread is established in connector, drill bit lower end is provided with external thread, and the upper end of cutting ring is provided with internal thread, and the lower end of drill bit connects cutting ring.The utility model structure is simple, easy to operate, because the lower end of drill bit is provided with cutting ring device, ensure that the integrality of soil sample and accurate layering.Cutting ring lower end is provided with sharp edge, reduces resistance during soil sample, has been suitable for various soil (comprising frozen soil).Drill bit is open, ensure that the convenience of soil sample, accelerates the speed of sampling, improves work efficiency.The lateral wall of drill bit and drill body is carved with scale, and conveniently the personnel of fetching earth are convenient for measuring soil layer length, are convenient to carry out multi-level soil layering sampling, calculate volume also more convenient simultaneously.

Description

The multi-level cutting ring formula of a kind of many soil properties fetches earth earth boring auger
Technical field
The utility model relates to a kind of soil investigation utility appliance, especially relates to the multi-level cutting ring formula of a kind of many soil properties and to fetch earth earth boring auger.
Background technology
The element task of soil investigation is carried out, for the mensuration of the physicochemical property of pedotheque provides material base during collecting soil sample.The collection of pedotheque at present more adopts soil drilling method, core cutter method, carry out the mensuration of soil physical chemistry, biology and the soil weight, existing earth boring auger mainly contains two kinds, a kind of is on drill bit, cut out a narrow and small gap, another is drill bit is cut formula open completely, and the former cannot ensure the accurate layering of earth pillar, and the inconvenience that fetches earth, the latter can not ensure the integrality of earth pillar, is especially difficult to accurate layering to sand loam or frozen soil and maintains the original state soil.
Summary of the invention
The utility model can not adapt to various soil for existing earth boring auger and obtain complete original state soil layer and cannot carry out the problem of accurate layering to earth pillar, proposes the multi-level cutting ring formula of a kind of many soil properties and to fetch earth earth boring auger.
The technical solution of the utility model is: the multi-level cutting ring formula of the many soil properties of the one for soil sample fetches earth earth boring auger, comprise cutting ring, drill bit, drill body, handle and auxiliary hammer, handle is connected with drill body by the first connector, drill body is connected with drill bit by the second connector, screw thread is established in connector, drill bit lower end is provided with external thread, and the upper end of cutting ring is provided with internal thread, and the lower end of drill bit connects cutting ring.
The multi-level cutting ring formula of the many soil properties of described one fetches earth earth boring auger, and described handle and drill body are solid stainless steel.
The multi-level cutting ring formula of the many soil properties of described one fetches earth earth boring auger, and the internal diameter of described drilling pipe is 20mm ~ 35mm.
The multi-level cutting ring formula of the many soil properties of described one fetches earth earth boring auger, and described drill bit is that semicircle is open.
The multi-level cutting ring formula of the many soil properties of described one fetches earth earth boring auger, and the lower end of described drill bit is provided with cutting ring device.
The multi-level cutting ring formula of the many soil properties of described one fetches earth earth boring auger, and described drill body and drill bit lateral wall are provided with scale.
The beneficial effects of the utility model are: 1. the utility model structure is simple, easy to operate, because the lower end of drill bit is provided with cutting ring device, ensure that integrality and and the accurate layering of soil sample.2. mouthful edge of a knife that buries of the utility model cutting ring is sharp, reduces resistance during soil sample, suitable various soil (comprising frozen soil).3. the utility model drill bit is open, ensure that the convenience of soil sample, accelerates the speed of sampling, improves work efficiency.4. the utility model is carved with scale on the lateral wall of drill bit and drill body, and conveniently the personnel of fetching earth are convenient for measuring soil layer length, are convenient to carry out multi-level soil layering sampling, calculates volume also more convenient simultaneously.

In figure, 1 is handle, and 2,4 is connector, and 3 is drill body, and 5 is drill bit, and 6 is cutting ring, and 7 is scale, and 8 is rubber tup, and 9 is iron body and iron handle, and 10 is antiskid sleeve.
Embodiment
Embodiment 1: composition graphs 1 and Fig. 2, a kind of multi-level cutting ring formula of many soil properties that is used for fetches earth earth boring auger, comprise cutting ring 6, drill bit 5, drill body 3, handle 1 and auxiliary hammer Fig. 2, the internal diameter of drill bit 5 is 30mm, and handle 1 is connected with drill body 3 upper end by the first connector 2, and drill body 3 lower end is connected with drill bit 5 by the second connector 4, screw thread is established in connector, drill bit 5 lower end connects cutting ring 6, and drill bit 5 lower end is provided with external thread, and cutting ring 6 upper end is provided with internal thread.Cutting ring 6 keen edge, drill body 3 and drill bit 5 lateral wall are provided with scale, and whole earth boring auger all adopts stainless steel.
Auxiliary hammer Fig. 2, comprise rubber tup 8, iron body and iron are 9 and antiskid sleeve 10.
Principle of work: step 1: handle 1 and drill body 3 are tightened, in like manner tightens drill bit 5 and cutting ring 6, forms complete earth boring auger;
Step 2: the cutting ring 6 of earth boring auger and drill bit 5 are vertically inserted sampling soil, and soft soil can assist hammer, direct two hand squeeze grip two ends, the auxiliary hammer of hard soil beats the center of earth boring auger handle, after reaching predetermined depth, slightly rotate, extract earth boring auger;
Step 3: if measure unit weight, the soil column in drill bit is got its standard volume, gently put into sample box, bring indoor into and carry out measuring; If what measure is other physicochemical property of soil, as required, mix by the soil column of different soil, loading sample box or sample sack, complete sampling.
