Problems solved by technology

[0002] In the process of geological inspection, it is necessary to sample the low-lying soil. The traditional sampling cylinder collects the soil at various depths together. When the soil is separated at different depths, it is easy to cause confusion and mixed pollution of soil samples at different depths, resulting in sampling Inaccurate, affecting the accuracy of test results

Embodiment 1

[0021] See Figure 1-5 In an embodiment of the present invention, a sampling device for geological inspection includes an equipment body; the equipment body includes a drill bit 1 and a drill barrel 2; the upper end of the drill bit 1 is fixedly connected with a drill barrel 2, and the upper end of the drill barrel 2 is connected with a drive Device, the drill barrel 2 is nested with a plurality of sampling barrels 8 distributed equidistantly, the sampling barrel 8 is a cylindrical barrel, and the side wall of the sampling barrel 8 is provided with a fan-shaped through groove 9 which communicates with the outside atmosphere, and the fan-shaped through groove 9 is nested with an outer scraper 10, the end of the outer scraper 10 is hinged with the inner wall of the fan-shaped through slot 9 through the first hinge seat 12, the hinge shaft of the first hinge seat 12 is sleeved with a torsion spring 13, and one end of the torsion spring 13 is connected with The outer scraper 10 abu...

Embodiment 2

[0024] The difference between this embodiment and the first embodiment is: after scraping the soil, the drill barrel 2 rotates in the opposite direction to achieve the rapid lifting of the drill barrel 2. When the sampling barrel 8 on the upper part of the drill barrel 2 is separated from the drilling pit on the ground, the lower part The sampling barrel 8 is still in the drilling pit. If the drilling barrel continues to rotate at this time, under the action of centrifugal force, the soil in the upper sampling barrel 8 is squeezed by the external scraper 10, which may cause the soil to be completely thrown out of the sampling barrel 8, causing soil In order to solve the above problem; the inner side of the outer scraper 10 is provided with an inner hinge plate 14, the end of the inner hinge plate 14 is hinged with the inner wall of the fan-shaped through groove 9 through the second hinge seat 15, and the inner wall of the sampling cylinder 8 is provided with an inner wall The li...

Embodiment 3

[0026] The difference between this embodiment and the second embodiment is that: in order to achieve the collection of water samples in the soil at a specified depth; the drill bit 1 is provided with a pumping cavity 101, the side wall of the drill bit 1 is provided with a pumping hole 17, and the pumping hole 17 is nested There is a filter; the pumping cavity 101 is connected with a pumping pipe 18, which penetrates the drill barrel 2 and extends to the top of the drill barrel 2, the pumping pipe 18 is connected with a water inlet pipe 19 through a rotary joint, and the water inlet pipe 19 is connected with a pumping mechanism, The pumping mechanism performs pumping operations through the pumping pipe 19, the pumping cavity 101, and the pumping hole 17, and collects water samples.

[0027] The pumping mechanism includes a pumping cylinder 20 communicating with a water inlet pipe 19, and a first check valve is provided at the place where the water inlet pipe 19 communicates with t...

Abstract

The invention discloses sampling equipment for geological detection. The sampling equipment comprises an equipment body, wherein the equipment body comprises a drill bit and a drill barrel, an upper end of the drill bit is fixedly connected with the drill barrel, an upper portion of the drill barrel is connected with a driving device, a plurality of sampling barrels distributed at equal intervalsare embedded in the drill barrel, fan-shaped through grooves are formed in side walls of the sampling barrels, outer scraping plates are embedded in the fan-shaped through grooves, and protruding strips integrally formed with the outer scraping plates are fixedly connected. The sampling equipment is advantaged in that by arranging the sampling barrels, the fan-shaped through grooves, the outer scraping plates, a convex strip and a torsion spring, soil samples with different depths are accurately sampled, and mixed pollution of the soil samples with different depths is avoided; through an innerhinge plate and a limiting groove, soil is prevented from being thrown out when the drill barrel is lifted; through the arrangement of a drill bit with a water pumping cavity and a water pumping hole, a water pumping pipe and a piston disc driving mechanism linked with a stepping motor through a magnetic coupling, collection of a water sample at a specified depth is realized.

Description

Technical field [0001] The invention relates to the field of geological detection equipment, in particular to a sampling device for geological detection. Background technique [0002] In the process of geological inspection operations, it is necessary to sample the low soil. The traditional sampling tube collects the soils of various depths. When the soils of different depths are separated, the soil samples of different depths are prone to confusion and mixed pollution, resulting in sampling Inaccuracy affects the accuracy of the test results. Summary of the invention [0003] The purpose of the present invention is to provide a sampling device for geological inspection to solve the problems raised in the background art. [0004] In order to achieve the above objectives, the present invention provides the following technical solutions: [0005] A sampling equipment for geological inspection, comprising an equipment body; the equipment body includes a drill bit and a drill tube, the ...
