The present invention relates to a casing Oga slime discharge device of the ground excavation device that can be discharged without scattering the slime such as the excavated soil in the excavation of the pile ball to put the pile in the ground during various civil works .

Generally, casing augers or casing augers are used to drive piles in the ground for the construction of various dams and large-scale constructions. A hammer drill device which is assembled in multiple stages on the output shaft at the lower end of an auger machine which is suspended and mounted on a vertically mounted leader and excavates the ground, and the hammer drill is rotated in the opposite direction to the hammer drill device. It is composed of a casing rod device for inducing the discharge action of the slime, such as earth and sand excavated, disposed by the device.

The output shaft is installed at the center of the lower end of the organ machine, the output of the hammer drill device is installed vertically, the hammer drill device is connected to the output shaft in a multi-stage assembly and the lower end of the hammer rod is connected It is composed of a hammer drill, and the casing rod device has a larger diameter than the hammer drill device has a structure in which the casing rod surrounding the hammer drill device is connected in multiple stages.

Conventional ground excavation device is the slime excavated as a hammer drill is moved up the inner circumferential surface of the casing rod by the air pressure ejected from the hammer drill device, or is moved by a screw blade spirally attached to the outer circumference of the hammer rod The uppermost casing rod of the casing rod device is configured to be discharged to the outside through a discharge hole formed in the assembled skirt tube.

However, when the slime is discharged through the discharge hole of the skirt tube installed at the lower end of the organ machine as described above, the discharged slime is scattered in the high air, so that the pit drilling site is scattered, that is, the clock by the dust and stones, etc. Is not only poor, and the working environment worsens, which not only causes a lot of problems in the work, but also causes serious problems such as air pollution. Furthermore, the slime discharged to the outside contains coarse grains of stone. As well as the workers driving the excavator, there was a problem that poses a threat to the workers on the ground.

Therefore, in order to solve the above problems, recently, a means for installing a separator is adopted so that the slime discharged to the outside does not fall to the leader side, but this also has a problem in that the slime is scattered in the air, and thus the effectiveness has not been achieved.

The present invention was conceived based on the same problems as the prior art, and accumulated by many years of experience accumulated in the manufacturing process and construction site of the organ machine and its parts, and installed at the lower end of the organ machine in opposite directions. Apart from the output shaft and the skirt tube, a slim collecting cylinder that does not rotate at the lower end of the organ machine is installed. The hose can be discharged directly into the loading box of a certain dust collecting chamber or a dump truck, so that the slime such as soil, crushed stone, and lumps discharged during pile drilling can be discharged directly to the set place without scattering to the outside. It was devised.

The present invention as a means for achieving the above object, to install the casing rod device on the output shaft for rotating the hammer drill device on the lower end of the organ machine, and the skirt tube rotating in the opposite direction while wrapping the hammer drill device A protective tube having a diameter larger than that of a skirt tube installed so as to be rotatable at the lower end of the organ machine, and installed in a fixed state on the body of the organ machine so as not to rotate; A slime collecting cylinder for collecting slime discharged from the discharge hole of the skirt tube assembled between the lower flange of the protective tube and the upper end of the upper casing rod; And a slime discharge part having a discharge port for discharging the collected slime into the discharge hose on both sides of the slime trapping cylinder so that the slime discharged from the discharge hole of the casing rod can be dropped and discharged to a predetermined place. It is.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view showing a state of use of the present invention, Figure 2 is a cross-sectional view showing the state of use of the present invention, Figure 3 is a view showing a cross-sectional view of the AA line of Figure 2, the reference numeral 1 represents an organ machine, The organ machine 1 is suspended from a leader installed vertically high on the tip of a crawler traveling device (not shown) and installed to move up and down by an operation cable.

In addition, the organ machine 1 is configured such that the output shaft (not shown) is rotated by the rotational output of the motor power is reduced by the planetary reduction gear device, the female joint (2) is installed on the output shaft, The skirt tube (3) surrounding the output shaft and the female joint (2) is further decelerated by a planetary gear device engaged with the spline of the output shaft, and the skirt tube (3) is opposed to the output shaft. It is configured to rotate in the direction.

A protective tube 4 having a diameter larger than the outer diameter of the skirt tube 3 is installed in a fixed state of the lower body portion 1a of the organ machine 1.

On the lower flange 4a of the protective tube 4, a slime collecting cylinder 5 surrounding the skirt tube 3 is assembled as a bolt.

On both sides of the slime collection cylinder (5) is provided with a discharge portion (6) for discharging the slime discharged from the discharge hole (3a) of the skirt tube 3 to the outside, and also the discharge port of the discharge portion (6) A discharge hose 7 for dropping the slime to the set place is assembled at 6a.

The slime collection cylinder (5) is the skirt tube (3) so that the slime discharged from the discharge hole (3a) of the skirt tube (3) can be discharged to the outside through the discharge portion 6 while collecting the entire amount of the slime discharged to the outside A ring-shaped packing 8 is interposed between the lower flange 3b of the lower end and the inner peripheral surface of the lower end of the slime collecting cylinder 5.

The ring-shaped packing (8) is installed to be attached to the inner peripheral surface of the lower flange (3b) is configured to prevent the leakage of slime while allowing the rotation operation of the skirt tube (3).

In addition, the discharge part 6 was formed to open and close the door 6b to clean the interior of the discharge part 6 and the slime collection cylinder (5).

The hammer rod 9 is assembled in multiple stages to the female joint 2 attached to the output shaft of the organ machine 1, and the casing rod 10 to the lower flange 3b of the skirt tube 3. Is assembled in multiple stages.

Referring to the operation of the present invention configured as described above are as follows.

Excavation work is performed by hammer hammer (not shown) assembled at the lowermost end of the hammer rod 9 assembled in multiple stages to the arm joint 2 attached to the output shaft of the organ machine 1 while hitting the ground. The casing rod 10, which is assembled in multiple stages to surround the hammer rod 9 and the hammer drill, rotates in the opposite direction to the hammer drill and is excavated by excavation of the hammer drill. Directing the slime of the back upward and acting to raise the skirt tube 3 assembled on the lower end side of the organ machine 1 is the same as the conventional art, and in the prior art, the upward movement to the skirt tube 3 The slime is configured to be discharged to the outside through the discharge hole (3a) so that the slime is scattered in all directions from the air where the organ machine (1) is located, but in the present invention is discharged from the skirt tube (3) Lyme slime collecting cylinder (5) it is constructed so as to fall into place to set the total amount collected.

That is, the slime collection cylinder 5 attached to the lower flange 4a of the protection cylinder 4 fixedly attached to the organ machine 1 completely surrounds the outer circumference of the skirt tube 3, and also Since the ring-shaped packing 8 is interposed between the lower inner circumferential surface of the slime collecting cylinder 5 and the lower flange 3b of the skirt tube 3, the slime discharged to the discharge hole 3a of the skirt tube 3 is transferred to the outside. Without leaking into the discharge section 6 provided on both sides of the slime collecting cylinder (5), the slime introduced into the discharge section 6 is discharged directly to the discharge hose (7) through the discharge port (6a) By dropping the discharge hoses (7) on the slime storage tank or dump truck installed on the ground, it is possible to drop and discharge directly to the set place without scattering the slime discharged during the drilling of the pile into the atmosphere It is.

According to the present invention as described above, when the pile hole is excavated using the casing organ device, the slime discharged from the casing tube is lifted up by the casing rod, and thus the slime collecting cylinder collects the entire amount of the slime. In addition to the effect of not scattering to the outside, the discharge hose that drops the slime can be discharged directly into the slime storage tank or the dump truck's loading box, which makes the processing of the excavated slime very easy. Since it is not scattered in the atmosphere, it is a very practical design that can improve work efficiency by improving the environment of the workplace.
