Problems solved by technology

[0002] At present, there is no drill bit that can form a rectangular hole, and the drilled hole is not easy to be close to the adjacent building, and the surface of the adjacent building cannot be cleaned. The large inclination of the drilled hole makes the function of the bored pile narrow, which is very important. To a large extent, the construction of some major projects is restricted, which directly affects the development of the national economy.

Abstract

The invention discloses a rectangular pore-forming bit, and belongs to the engineering machinery technology. The rectangular pore-forming bit comprises a transmission assembly, two disc sliding plates, four horizontal bits, four wire brushes, and a vertical bit. The rectangular pore-forming bit has the advantages that the drill hole inclination is small, the rectangular pore-forming bit can be close to an adjacent building, the surface soil of the adjacent building can be removed, and the adjacent building cannot be damaged.

Description

technical field [0001] The invention relates to engineering machinery technology, in particular to a rectangular hole-forming drill bit. Background technique [0002] At present, there is no drill bit that can form a rectangular hole, and the drilled hole is not easy to be close to the adjacent building, and the surface of the adjacent building cannot be cleaned. The large inclination of the drilled hole makes the function of the bored pile narrow, which is very important. To a great extent, it restricts the construction of some major projects and directly affects the development of the national economy. Contents of the invention [0003] The object of the invention is to provide a rectangular hole-forming drill bit with small drilling slope, which can be close to the adjacent buildings, can remove the surface soil of the adjacent buildings, and does not damage the adjacent buildings. The object of the present invention is achieved like this, it comprises transmission ass...
