Description

A sampler device for investigation of ground using hand drill}

The present invention relates to a sample collector for a ground survey, and more particularly, in a narrow area where large mechanical equipment cannot be installed, a worker can move and install it in a state where it is easy to carry and safely collect a soil sample. It relates to a sample collector for a ground survey using a portable hand drill.

In general, soil has various functions, such as a food production function, a groundwater cultivation function, a flood control function, a purification function, and an ecosystem function.

Soils with various functions as described above are subjected to geological investigation to acquire data necessary for the construction of foundation construction in the early stage of development, and are being developed for appropriate use through analysis through geological investigation.

Looking at the method of collecting a sample for a conventional soil geological survey, an appropriate amount of soil was initially collected using a pickaxe, a shovel, a seedling shovel, etc., but then the soil sample was collected using a separate collector, at this time the soil surface After removing foreign substances such as weeds and organic matter, soil samples were collected with a collector.

Looking at the extractor equipment applied to the above-mentioned existing geological survey, there is an example of using a soil sampler with a prime mover such as a geoprobe attached to a vehicle, but this is an area or narrow area where the vehicle cannot enter because the equipment is large. In one area, there was a problem that soil samples could not be collected.

In the narrow area as described above, a manual harvester is mainly applied. In this case, since it is necessary to collect the soil at a certain depth by inserting the harvesting rod into the stratum by manpower, there is a problem that requires a lot of time and labor, and furthermore, because the sample is disturbed.

The hand drill 100 is the same as the known one, and when power is applied, the drive shaft 110 provided at the front end of the body rotates, and the drive shaft 110 has a coupling 400 for coupling the core drill 500 . ) are combined.

The guide member 200 is erected perpendicularly to the ground, and guide rails 210 for guiding the rail block 300 are formed on both sides in the longitudinal direction, and on one surface of the rack gear ( 220) is formed. In addition, a horizontal support 230 is formed at the lower end of the guide member 200 to protrude outward so that the user can step on it or fix it on the ground through a load.

Accordingly, when the user steps on the upper surface of the support 230 and then moves the rail block 300 , the rail block 300 can be easily moved up and down.

In addition, the pinion gear 340 meshes with the rack gear 220 formed on the guide member 200 , and the pinion gear 340 moves up and down along the rack gear 220 according to the rotation direction. The pinion gear 340 is fixed to the rail block 300 through a rotation shaft 342, and a rotation lever 345 for rotating the pinion gear 340 is provided at an end of the rotation shaft 342. .

Accordingly, when the rotation lever 345 located on one side of the rail block 300 is rotated, the rotation shaft 342 is rotated and the pinion gear 340 is rotated, and the pinion gear 340 is rotated. It moves along the rack gear 220 .

The rail block 300 is coupled to surround the guide member 200 to move up and down along the guide rail 210, and on one side drill the hand drill 100 so that it can be detachably fixed. A guide 320 is formed, and the guide member 200 is slide-inserted into the guide rail 210 on both inner walls of the vertical guide hole 310 and the vertical guide hole 310 so that the guide member 200 passes through the other side. A projection 312 is formed.

That is, when the rail block 300 is coupled to the guide member 200, the guide rail of the guide member 200 ( 210) is coupled to enable the rail block 300 to move up and down with respect to the guide member 200 .

The drill fixing part 320 is formed to penetrate vertically in the rail block 300 , and a locking end is formed on the upper side so that when the hand drill 100 is mounted, the body constituting the hand drill 100 is seated. It is stably positioned and fixed integrally through a coupling means including a separate fastener and the like.

The coupling 400 may be provided in various lengths according to the moving distance of the core drill 500 , and integrally connects the tip drive shaft of the hand drill 100 and the core drill 500 . That is, a driving shaft fixing part 410 is formed on one side of the coupling 400 to rotate integrally with the driving shaft, and a drill fixing part ( 420) is formed.
That is, the depth of the core to be formed on the ground through the core drill 500 is determined.

The core drill 500 is a well-known technology for forming a core on the ground. A space is formed inside the hollow, and a fixing part 510 is formed so that one end is fixed to the drill fixing part 420 . And the other end is provided with a bite 520 to form a hole in the ground during rotation.

The sample collection tube 600 may be made of various materials such as metal, wood, synthetic resin, etc., and is slide-inserted into the space of the core drill 500 to form an integral body.

Here, it is preferable to insert the sample collection tube 600 inside the core drill 500 so that they are integrally fixed.

This allows a hole 530 to be formed on the outside of the core drill 500 in an orthogonal direction, and a hole 630 to be formed in an orthogonal direction on one side of the sample collection tube 600 so that the holes coincide with each other. When fixed through a separate coupling pin 560 in this state, the sample collection tube 600 can be integrally coupled to the core drill 500 .

The state of use of the sample collector for ground investigation using a portable hand drill according to the present invention configured as described above will be described as follows.

When transporting, as shown in FIG. 1 , a size that an operator can hold by hand, that is, a hand drill 100 , a guide member 200 , a rail block 300 , a coupling 400 , and a core drill 500 . , it is enough to separate the sample collection tube 600 and move it to the installation location.

At the time of installation, as shown in FIGS. 2 and 3 , the rail block 300 is installed on the guide member 200 , the hand drill 100 is installed on the rail block 300 , and then the hand drill 100 The coupling 400 is coupled and the core drill 500 is coupled to the coupling 400 , and the sample collection tube 600 is installed in the core drill 500 at the same time.

At the time of operation, as shown in FIG. 3 , after positioning the guide member 200 at the installation location, the operator's foot is stepped on the support 230 , and then the rotary lever 345 is rotated. Then, the rotation lever 345 rotates to rotate the pinion gear 340 , and the pinion gear 340 moves downward along the rack gear 220 . At this time, the hand drill 100 installed on the rail block 300 rotates the coupling 400 and the core drill 500 with a driving force according to the application of power to form a core on the ground. After that, when it is input to an appropriate depth, the driving is stopped and the sampling is completed when the sample collection tube 600 is separated from the core drill 500 .

Here, if a depth is required during the work, after separating the coupling 400, the work may be performed by replacing the coupling 400 with a suitable length.

As another example, as shown in FIGS. 4 and 5 , it will be possible to provide a fixing plate 700 that allows the guide member 200 to stably maintain a vertical state with respect to the ground.

The fixing plate 700 is provided with a plurality of ground fixing wedges 710 for underground fixing on the bottom surface, a core guide hole 720 is formed through the center of the surface, and the guide member 200 is formed on the top surface of the fixing plate 700. What is necessary is to apply the fixing member 730 in which the slide groove 732 is formed so that the lower support 230 can be fitted and fixed.

That is, the lower end support 230 of the guide member 200 may be fixed by inserting it into the slide groove 732 .

Here, the slide groove 732 may be formed along the circumference on the outer circumferential surface based on the center of the core guide hole 720 formed on the surface of the fixing plate 700 .

In addition, a hinge 750 is fixed to the upper surface of the fixing plate 700 so that the guide rod 740 having a handle at the top is rotatably fixed, so that the operator can hold and press the fixing plate 700 to be fixed. will be.
