In the figure: the mutual spacing or dimensions are exaggerated for the purpose of showing the positions of the various parts, and the schematic illustration is only schematic.
Wherein: 1. the device comprises a collecting device 2, a scraping rod 3, a cross rod 4, a drill bit 5 and a drill rod.
Detailed Description
It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the utility model. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs.
The top of the rotary drilling rig is provided with a cylindrical drill bit, some excavated sand and stones can be temporarily stuck on the inner wall of the drill bit in the pile hole construction process, the downward extrusion pressure is higher in the construction process, the sand and stones on the inner wall of the drill bit are compactly plugged and are not easy to discharge; the conventional mode is that the drill rod 5 drives the drill bit 4 to rotate and then stops instantaneously, and the drill rod and the drill bit collide with some stops on the drilling machine during stopping, which is equivalent to knocking the drill bit to loosen compact sand and stone in the drill bit and discharge the compact sand and stone. But in the process of taking out sand, the drill rod and the drill bit collide with some stops on the drilling machine to generate larger noise, and the requirements of municipal construction are not met.
