Abstract

The invention relates to a device manufacturing method and product for researching earth sampling in wild environment. One end of the product is grinded as annular blade shape; another end of the product is welded and sealed by a steel board; a through hole is drilled at the near sealed end; the method cuts an annular wall between the annular blade and the through hole at the 1/3-1/2 position as the cavity cover; a fixed sleeved ring is fixed of the cavity cover is fixed outside the earth drilling body; a through is sealed with a through at the near sealed end; a cavity opening is arranged on the annular wall between the annular blade and the through hole at the 1/3-1/2 position; an corresponding earth cavity cover is on the cavity opening; a fixed sleeved ring is fixed of the cavity cover is fixed outside the earth drilling body; a tightened bolt is arranged on the fixed sleeved ring. The manufacturing method above is simple and the material picking is convenient; the product is portable and convenient to use, which not only an pick the earth pillar sample, but also the original earth sample at the different depth and layer in one time; the method reduces the working quantity of the earth pillar sampling and the method never destroys the environment of the earth sample.

Description

A kind of earth column geotome manufacturing method and product

Technical field

The present invention relates to a kind of device manufacturing method and product of field study soil sampling, i.e. a kind of manufacture method of earth column geotome and product.

Background technology

Existing field study soil sampling generally takes core cutter method to get former state soil; In order to study the distribution of root system in soil, generally take the earth pillar method, need to excavate soil profile, workload is big, and excavates to break ground sample ground environment is had bigger influence, and people do not need the sampling soil method and apparatus that excavates in exploration.

Summary of the invention

The purpose of this invention is to provide a kind of manufacture method and product that does not need the manufacture method and the product, particularly earth column geotome of the soil sample equipment that excavates.

The objective of the invention is to realize as follows: a kind of manufacture method of earth column geotome; It wears into cutting ring mouth shape to an end with a steel pipe, and other end steel plate welded closure is bored a through hole at nearly blind end, and the ring wall that extracts 1/3-1/2 between the near-ring edge of a knife and the nearly through hole is the provincialism lid, the retaining collar that earth boring auger is external to have fixing provincialism to cover.

The manufacture method of above-mentioned a kind of earth column geotome, the internal diameter and the earth boring auger body diameter of the retaining collar of its provincialism lid closely cooperate, and are provided with a clamp stud.

Adopt said method to make earth column geotome, its drill body is a tubulose, inner chamber is a cylindrical chamber, one end becomes cutting ring mouth shape, and other end steel plate welded closure has a through hole at nearly blind end, on the ring wall of 1/3-1/2 between the near-ring edge of a knife and the nearly through hole accent is arranged, the provincialism lid that a correspondence is arranged on the accent, earth boring auger is external the fixedly retaining collar of provincialism lid, and retaining collar is provided with a clamp stud.

The earth column geotome that adopts said method to make, manufacture method is simple, draws materials conveniently, and general machining factory promptly can processing; The product of manufacturing carries, uses very convenient in the investigation sampling, the post sample not only can fetch earth, can also once get the former state soil sample of different depth or aspect, reduced the workload of earth pillar sampling, simultaneously do not destroy sample ground environment, in the field study for many years of this problem, play a significant role.

The present invention is further described below in conjunction with accompanying drawing.

Specific embodiment:

Embodiment 1

According to Fig. 1,2,3, the steel pipe that intercepts an internal diameter 11cm, tube wall 0.5cm, long 120cm is drill body (1), one end is worn into cutting ring mouth (5) shape, other end steel plate welded closure, bore a through hole (4) at nearly blind end, extracting between the near-ring edge of a knife and the nearly through hole 1/3 ring wall is provincialism lid (2), earth boring auger is external the fixedly retaining collar (3) of provincialism lid, the internal diameter of provincialism lid retaining collar is slightly larger than 11.5cm and the earth boring auger body diameter closely cooperates, and adorns a clamp stud on the provincialism lid retaining collar; The earth column geotome inner chamber is cylindrical chamber (6), is a kind of earth column geotome provided by the present invention.
