本発明は、コンクリ−１〜杭等の建込用の孔を土中に掘
削づるためのアースオーガに装備する土塊かき落し用の
スクレーバ装置に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention is a scraper device for scraping off soil clods, which is installed on an earth auger for excavating holes for concrete construction, such as piles, etc. Regarding.
（従来の技術）
従来、アースオーガのスクリューにより地上に搬出され
た土塊は、スクリューの回転や振動によってその羽根面
から自然に滑落するに任されていた。(Prior Art) Conventionally, earth clods carried to the ground by the screw of an earth auger were allowed to naturally slide down from the blade surface due to the rotation and vibration of the screw.

の近傍で作業している者に危険を及ばずことがあった。(Problem to be solved by the invention) However, with this method, if the soil being carried out has a high viscosity, it will not easily slide down from the screw blades and will not slide along the screw blades. Because the earth auger only slid down after being raised to a considerable height above the ground, it did not pose any danger to those working near the earth auger.
そこで本発明は、アースオーガのスクリューにより地上

かき落し用のスクレーバ板とを突設したことである。(Means for Solving the Problems) A technical means for solving the above problems is that the screw is rotatably supported on the outer periphery of the screw of the earth auger by a column of the earth auger. A cylindrical body positioned concentrically is provided, and a roller wheel is provided which contacts the upper and lower surfaces of the blade of the screw from the inner circumferential wall of the cylindrical body, respectively, and a clod scraper is positioned opposite to the two surfaces of the blade of the slurry 1-1. This includes a protruding scraper plate for cleaning.

覆る。The rotational movement of the cylindrical body relative to the screw is controlled by roller wheels in contact with the upper surface of the screw blades for upward rotation of the screw, and by roller wheels in contact with the upper surface of the screw blades for rotation of the screw in the downward rotation direction. They are each restrained by roller wheels that come into contact with the underside of the screw blades. Therefore, when the screw rotates, the cylindrical body also rotates, and on the other hand, for the vertical movement of the screw, the rotation angle of the screw blades corresponds to the width of the vertical movement (the J1 cylindrical body Rotate relative to the screw.

筒１０の内周部に回転可能に保持している。Next, the support body 5 is composed of a support cylinder 10 on the outer peripheral side and a rotary cylinder 11 on the inner peripheral side, which are each formed into a cylindrical shape. The support arm 12 protruding from the outer periphery is attached to the aggregate 13 of the branch office 2.
As shown in the figure, it is identified to the support column 2 by assembling (pull). Also, on the inner circumferential wall of the support tube 10 and the outer circumferential wall of the rotating tube 11, there are corresponding roller supports (J river protrusion). Article 14.15
The rotary cylinder 11 is rotatably held on the inner circumference of the support cylinder 10, with a large number of ball-shaped rollers 16 interposed between the protrusions 14 and 15.
