Description

Groove type drill pulling tool

Technical Field

The utility model relates to an appurtenance field for the geological survey, in particular to groove type brill pull-out instrument.

Background

The groove drill is the most common instrument for revealing the surface lithology in the field geological survey of the quaternary, and the main pulling mode is to manually pull out the groove drill directly after rotating a groove drill handle and then scrape off the outer semicircular rock core of the drill by a scraper, thereby revealing the characteristics of the rock core.

The pulling mode mainly depends on manual vertical pulling, and can be conveniently taken out from softer soil with good plasticity, but the slot drill is difficult to take out from hard soil or geological with high viscosity, time and labor are wasted, the adverse conditions such as bending of the drill rod, even breakage of the drill rod and the like are easily caused, and irretrievable economic loss is caused, so that a slot drill pulling tool is needed to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the problem that exists among the above-mentioned prior art, provide a groove type brill pull-out instrument.

The technical scheme of the utility model is that:

the method comprises the following steps:

the inner sleeve is used for being sleeved on the drill rod below the handle of the groove drill, the top of the inner sleeve is further fixedly sleeved with a top disc, and the top disc is provided with a shape positioning groove for accommodating the handle;

the outer sleeve is sleeved on the inner sleeve, the outer sleeve and the inner sleeve are connected through inner and outer threads, and the inner sleeve extends out of the outer sleeve;

the handle is arranged in the circumferential direction of the section of the inner sleeve extending out of the outer sleeve.

Preferably, the lower end of the outer sleeve is circumferentially provided with a pedal.

Compared with the prior art, the utility model provides a pair of groove type brill pulling tool, its beneficial effect is:

1. the utility model discloses simple structure, convenient to use.

2. The utility model discloses an inner skleeve of rotating this device makes the interior muff jack-up slot type drill handle to the drilling rod that makes the slot type bore is extracted perpendicularly from the soil body, has guaranteed that the drilling rod is safe to be played effectively fast and has been pulled out.

3. The utility model discloses the practicality is strong, is worth promoting.

Detailed Description

An embodiment of the present invention will be described in detail with reference to fig. 1 to 3, but it should be understood that the scope of the present invention is not limited by the embodiment.

As shown in fig. 1, the utility model provides a groove-type drill pulling tool,

the method comprises the following steps: an inner sleeve 2 for being sleeved on the drill rod 3 below the handle 31 of the groove drill, as shown in fig. 2 and 3, wherein the drill rod 3 and the handle 31 of the groove drill are detachably connected through internal and external threads; the outer sleeve 1 is sleeved on the inner sleeve 2, the outer sleeve 1 and the inner sleeve 2 are connected through inner and outer threads, wherein the unscrewing direction of the outer sleeve 1 and the inner sleeve 2 is opposite to the unscrewing direction of the drill rod 3 and the handle 31, and the inner sleeve 2 extends out of the outer sleeve 1; the handle 21 is arranged on the periphery of a section of the inner sleeve 2 extending out of the outer sleeve 1.

Example 2

In addition to embodiment 1, in order to prevent the fixed outer sleeve 1 from rotating and to enable the device to work better, the pedals 11 are provided in the circumferential direction of the lower end of the outer sleeve 1.

Example 3

On the basis of the embodiment 1, the top of the inner sleeve 2 is also sleeved and fixed with a top disc 22.

Wherein, in order to make the drilling rod 3 can be better pulled out from the ground bottom, set up the shape positioning groove who holds handle 31 on the head disk 22, make handle 31 inject in the shape positioning groove to when turning handle 21, drilling rod 3 follows the rotation and deviates from the ground bottom.

Principle of operation

The utility model discloses during the use, as shown in fig. 1, when the cell type is bored and is beaten the underground and be difficult to extract, take off the handle is bored to the cell type, bore the drilling rod top cover down that exposes ground with the inner skleeve 2 of this device from the cell type, wear out from the top of inner skleeve 2 until the drilling rod top, install the handle that the cell type was bored after that, two feet are stepped on pedal 11 of outer skleeve 1 lower part, then rotate the handle 21 on the inner skleeve 2, make 2 spiral rises of inner skleeve, thereby make the handle that the 22 liftoff disc of jack-up cell type on the inner skleeve 2 jackings, make the stable perpendicular soil body of extracting of drilling rod 3.

To sum up, compared with the prior art, the utility model discloses a groove type bores pulling tool through the inner skleeve that rotates this device, makes the handle that the groove type bored in inner skleeve jack-up to the drilling rod that makes the groove type bore is extracted perpendicularly from the soil body, has guaranteed that the drilling rod is safe to be played effectively fast and has pulled out, this simple structure, and the preparation is convenient, and the practicality is strong, is worth promoting.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
