Description

Improved foreign substance device of screw for drilling machine

The present invention relates to a device for removing foreign substances from a screw, and more specifically, to remove dirt, sand, gravel, etc. (hereinafter referred to as `` foreign substances '') attached to the screw when the screw of the perforator is raised, and to discharge foreign substances collected in the lower auger. The present invention relates to an apparatus for removing foreign substances from a screw for an improved perforator.

To prevent dust and sedimentation for the pre-filed file driver, it is to reinforce the soft ground at various construction and construction sites and to remove scattered dust and soil from auger screws due to the use of the pile driver during foundation work. By removing the hassle of assembly and disassembly at each operation by installing and removing the earth and sand removal device that works with a rotating brush on the lifting shaft of the driver, the work condition of the auger screw is checked and checked while the auger screw is opened as it is. It is also easy to remove the soil from the auger screw that is returned after the drilling operation by a rotating brush containing moisture, and at the same time, it prevents dust from being scattered by absorbing the scattered dust and dropping it to the ground. .

However, the dust prevention and sedimentation for the conventional file driver removes the soil buried in the auger screw while a plurality of soil removal hairs are rotated around the rotation shaft. In this process, the soil removal hairs contact the screw by the rotational force of the rotation shaft. There is a problem in that it is difficult to effectively remove soil and the like stuck to the screw because the part to be transmitted and the impact to be transmitted are constant.

And to solve the above problems, the "apparatus for removing screw foreign matter for a perforator", which was previously filed by the applicant, is formed with a screw inducer for inducing and descending of a screw, an accommodating space part is formed inside, and the accommodating space part and a screw inducer A lower auger having a communication hole therebetween; A fixing part provided in the receiving space part, a driving shaft installed in the fixing part, a motor transmitting rotational force to the driving shaft, a plurality of wires installed on the driving shaft to remove foreign substances attached to the screw, and the rotating part A cleaning means including one or more idle rollers to impart a constant tension to the wire; It is installed in the accommodation space portion and the fixing portion and is composed of a cylinder that induces forward and backward movement of the fixing portion.

However, the conventional pre-applied screw foreign material removing device for the perforator is operated by the forward and backward cylinders on the inner bottom surface of the lower auger, so that during the operation of the cleaning means, foreign substances are introduced into the fixing part of the cleaning means. There was a problem in which malfunction of the cleaning means and the cylinder occurred.
