Description
Technical Field
The invention relates to a cutter holder of a rotary excavator, and belongs to the technical field of construction engineering piling machinery.
Background
At present, various building projects, such as houses, building foundation piles, road bridge foundation piles and the like, need to be subjected to foundation treatment pile driving or drilling piles and the like, and the rotary drilling rig is more and more widely used in the market due to high construction speed and low engineering cost; however, as more occasions are used, the applied foundation conditions are various, rock layers and the like are often encountered when the rotary drilling machine is used for rotary drilling, and the drilling tool for rotary drilling of the rock, namely the tool bit abrasion, of the rotary drilling machine can be increased, the tool bit of the conventional rotary drilling machine and the combination strength and structure of the tool bit are unreasonable, so that the abrasion is increased, the tool bit and the tool bit are required to be replaced frequently, the progress of engineering is easily affected, and the working efficiency is reduced.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the rotary excavator tool apron which is reasonable in structural design, convenient to use and install, abrasion-resistant, long in service life, capable of coping with various ground geology and improving working efficiency.
The invention aims at realizing the technical scheme that the tool apron of the rotary drilling machine comprises a connecting column and a tool apron body integrally connected with the upper end of the connecting column, wherein an axial connecting hole is formed in the lower end face of the connecting column, and a transverse positioning through hole penetrating through the axial connecting hole is formed in the side wall of the connecting column; the cutter holder body above be provided with a plurality of mounting holes that are used for installing the tool bit, and the hole central point of a plurality of mounting holes is in same rotatory circle face respectively.
As preferable: the connecting column is a square column, the upper end part of the square column is integrally connected to the bottom surface of the square tool apron body, three mounting tube seats which are respectively obliquely arranged and are respectively provided with a mounting hole are integrally cast and formed on the square tool apron body, and round holes which are transversely communicated with the mounting holes and used for disassembling the tool bit are formed in the side surface of the bottom of the mounting tube seat.
The invention has the characteristics of reasonable structural design, convenient use and installation, abrasion resistance, long service life, capability of coping with various ground geology, improvement of working efficiency and the like.
