FIG. 2 is an exploded perspective view of an apparatus for removing residual gravel of an auger according to an embodiment of the present invention, and FIG. 3 is a combined state view of FIG.

The apparatus for removing residual gravel 100 of an auger according to an embodiment of the present invention includes a body portion and a soil removal unit 14.

The body part includes a detachable part 12 to which the soil removing part 14 is detached and a bar type fastening part 22, 24 to be fastened to equipment such as an excavator.

Here, the detachable portion 12 is formed on one surface of the diaphragm 10 located at the center of the body portion, and may be formed in at least one shape. For example, in the case of forming a plurality of detachable portions 12, it is preferable to arrange them in a row. As a result, as shown in FIGS. 2 and 3, the detachable portions 12 may be formed in a plurality of rows in one or more rows.

In the embodiment of the present invention, the soil removing unit 14 is formed in a thick hair shape, so that each of the attaching / detaching units 12 can have a cylindrical shape with an open top. Therefore, the soil removal unit 14 can be fitted in the opening 12a formed in the upper part of the detachable part 12 or can be detached from the opening 12a. The reason why the soil removal unit 14 is detachable as described above is to facilitate the replacement of the soil removal unit 14 at any time.

One or more fastening holes 12b are formed in the outer surface of each detachable portion 12, and fastening members 16 such as bolts are fitted in the fastening holes 12b. That is, the fastening member 16 is for fixing the soil removal unit 14 sandwiched by the opening hole 12a. In other words, in the absence of the fastening member 16, the soil removal unit 14 may be arbitrarily disengaged from the opening 12a during the residual soil removal operation. However, since the soil removing unit 14 is fixed when the fastening member 16 is fastened, it is possible to prevent it from becoming dislodged.

The shape of the detachable portion 12 may vary depending on the shape and size of the soil removal unit 14, and the like. That is, the detachable portion 12 may be in any form as long as the soil removal unit 14 is fitted and removed.

The fasteners 22 and 24 are formed between the support plates 18 and 20 formed on the other surface of the diaphragm 10 so as to be spaced apart from each other. On the other hand, the fasteners 22 and 24 may be of any shape as long as they can be fastened to equipment such as an excavator other than a bar shape.

In the above embodiment of the present invention, the body is fastened to the equipment such as an excavator through fasteners. However, any equipment other than the excavator may be used as long as it can be coupled with the body and move the body. As described above, the equipment to be fastened to the body can be an example of the external actuators described in the claims of the present invention.

The soil removal unit 14 is detachably coupled to the detachable unit 12. [ The soil removal agent (14) directly abuts the soil remaining on the auger screw during drilling for the foundation work of the construction site to remove the soil.

For example, the soil removal unit 14 may be composed of any one of a wire steel wire, a PC steel wire, a release PC wire, and a PC wire.

In order to prevent this, the anti-wear ring 14a may be provided at the end portion of the soil removal unit 14 to prevent the end of the soil removal unit 14 from being used. That is, the wear prevention ring 14a may be coupled to surround the outer periphery of one end of the soil removal unit 14.

On the other hand, the soil removal unit 14 may be composed of a rubber plate having a plurality of strands at the ends thereof other than the wire steel wire, the PC steel wire, the release PC wire, and the PC wire. For example, the rubber plate may be rolled so that it is sandwiched in the opening hole 12a, or the lower portion of the rubber plate (i.e., the lower part in the shape of a cylinder) is inserted into the opening hole 12a.

In FIGS. 2 and 3, six detachable parts 12 are formed in each column, and the soil removing part 14 is fitted in each of the detachable parts 12. If necessary, the soil removing part 14 And the length of the soil removing unit 14 can be varied. For example, a longer length of the soil removal unit 14 may be used based on the depth of the auger screw 2 (the outer diameter of the screw blade). On the other hand, depending on the pitch (spacing between the screw blades) of the auger screw 2, the sand removing unit 14 may not be sandwiched by all of the attaching / detaching units 12, but may be sandwiched by one space.

FIGS. 4 to 8 are views for explaining an operation example of an apparatus for removing residual soil from an auger according to an embodiment of the present invention.

First, the residual soil removal apparatus 100 as shown in FIG. 4 is connected to an end of an arm 30 of an equipment such as an excavator as shown in FIG. That is, the knight that manages the excavator moves the arm 30 to fasten the end of the arm 30 to the fasteners 22 and 24 of the remaining soil removal equipment 100.

Then, the remaining soil removal device 100 moves the arm 30 to which it is fastened, and attaches it between the screw wings of the auger screw 2 (see Fig. 6). That is, when the auger screw 2 comes out of the casing 1 during the ground excavation work, the remaining soil 32 remains on the upper part of the screw blade. Therefore, when the soil removal unit 14 comes into contact with the residual soil 32 I will bring it to you. Preferably, the soil removal unit 14 is placed between the screw blades in advance at the beginning of pulling the auger screw 2 out.

Thereafter, if the residual soil removal device 100 is shaken to the left or to the right, that is, when the arm 30 is moved as if it were combed, the residual soil 32 between the screw blades of the auger screw 2 is removed 8). In other words, the residual soil 32 on the auger screw 2 can not be moved upward, and is removed by the residual soil removal equipment 100.

Although the above-described embodiment of the present invention has been described as shaking the residual gravel-removing apparatus 100 from side to side, it may be carried out while still standing still. For example, if the rotational speed of the auger screw 2 is sufficient, the residual soil 32 can be removed by the rotation of the auger screw 2 without rocking the residual soil removal device 100 left and right.

According to the embodiment of the present invention, the residual soil 32 placed on the auger screw 2 at the time of drilling for the foundation work of the construction site is removed by the residual soil removal equipment 100, It is possible to prevent an accident from occurring. This makes it possible to work more safely at the construction site.

On the other hand, in the embodiment of the present invention described above, air or water may be sprayed together when the residual soil removal apparatus 100 is used to remove residual gravel. Since the injection pressure of air or water can be sufficiently controlled, it is understood that a person skilled in the same kind of industry can fully understand it by well known technology.
