It relates to a screw dirt removal device.

In general, when constructing various buildings such as shopping centers and apartments, especially high-rise buildings, there are many cases where the ground is drilled for the construction of piles for the construction of an earthen wall. The operation of drilling the ground typically uses a hydraulic drilling machine (eg, a crane drilling machine) equipped with a screw.

The auger screw of the crane perforator is a device that drills a predetermined depth from the ground to the basement for the foundation work of a building construction site, and the auger screw operates in forward and reverse rotation according to the operation of the motor to make a hole perforated to a predetermined depth from the ground. do.

In other words, as shown in Fig. 1, a screw 12 (that is, an auger screw) is attached to the upper auger 13 of the perforator 11 of the crane 10, and the casing 15 is attached to the lower auger 14. After equipping, perform excavation. In this case, the screw 12 can move vertically inside the casing 15.

In addition, a ring bit (not shown) treated with special steel may be installed at the lower end of the screw 12 to facilitate drilling work on the ground. During excavation, the rotation direction of the casing 15 and the rotation direction of the screw 12 are opposite to each other. For example, when the screw 12 performs a forward rotation and excavates and drills the ground, the casing 15 rotates in a direction opposite to the rotation direction of the screw 12 and excavates and drills the ground. . Air is supplied through the screw 12 during excavation.

At this time, when the perforation of a predetermined depth is completed, the screw 12 is raised for perforation in the next step, and at this time, the soil is raised along with the screw 12 to be raised. In this way, the soil that rises up along the screw 12 is called Bhutto.

If the soil viscosity of the ground to be excavated is weak, most of the butt raised together with the screw 12 is discharged through the outlet (not shown) of the lower auger 14 and scattered around.

Conversely, when the soil viscosity of the ground to be excavated is strong, some of the butt raised together with the screw 12 is discharged through the outlet of the lower auger 14, but the remaining butt is placed on the screw 12 and thus the lower auger 14 You can climb to a higher upward direction. The buttocks rising upwards higher than the lower auger 14 are mostly dropped in the downward direction due to the rotation of the screw 12 and the wind. At this time, the falling butto hits the lower auger 14 and scatters.

Accordingly, when the worker is close to the construction site where the ground is drilled, it is hit by the scattering and falling butt and is seriously injured.

So, in order to solve this problem, a technique described in Korean Patent Registration No. 10-1937703 as shown in Figs. 2 and 3 has been proposed, the technical feature of which is an upper auger 13 on which a screw is mounted; and a casing ( 15) In the device for preventing the scattering of the buttocks of a crane drilling machine having a; lower auger (14) that is mounted to rise or fall according to the rotation of the casing (15), wherein the lower auger (14) Garimmak frame support portion 20 is fixedly installed; A screen frame 30 detachably installed on the lower auger 14 through the screen frame support part 20; And coupling and disengaging portions 23 and 24 for coupling and disengaging the shielding frame support portion 20 and the shielding frame 30; wherein the shielding frame 30 includes the lower auger 14 A metal scattering prevention film is provided in the lower central part where the butto discharged from the discharge port formed in the target is provided, and a scattering prevention cloth 57 is overlaid, and only a part of the screw mounted on the upper auger 13 is covered. It is installed on the lower auger 14 and is characterized in that the lower auger 14 ascends or descends together with the ascending or descending of the lower auger 14.

By the way, the technology described in Korean Patent Registration No. 10-1937703 has the advantage of preventing scattering of butt discharged from the lower auger 14 when drilling, but there is no means to remove the soil from the screw, so it can be left unattended. It is difficult to perform a stable drilling operation in the subsequent drilling operation, and there is a problem in that rapid drilling operation is difficult because the manager must directly remove the soil from the screw for a stable drilling operation.
