Problems solved by technology
[0002] At present, when construction machinery such as bulldozers and graders use rippers, due to the harsh and complicated working environment, the working load and impact load are relatively large, the racks and tooth tips of the rippers are subject to a large force, which is easy to cause damage and reduces the gear. The service life of the rod and tooth tip increases the cost and affects the benefit of the enterprise

The invention discloses a method for removing covering soil in a mine tunnel. According to the method for removing covering soil in the mine tunnel, a square connecting plate is included; lug plates provided with shaft holes are mounted on the two sides of the upper portion of the connecting plate, and a trapezoidal reinforcing plate is welded between the two lug plates; an arc-shaped toothed bar provided with a bucket tooth is welded to the middle of the bottom of the connecting plate; strengthening plates are welded between the peripheral edges of the square connecting plate and the outer wall of the toothed bar; an alloy sheath is mounted on the inner side of the arc-shaped curved surface of the toothed bar through a hinge pin; a tooth sleeve is mounted on the upper portion of the bucket tooth through a hinge pin; and two arc-shaped guide grooves are formed in the inner side wall of the lower portion of the bucket tooth and extend in the direction from the bottom of the bucket tooth to the bottom of the tooth sleeve, and the depths of the guide grooves are increased gradually in the extension direction of the guide grooves. Since the depths of the guide grooves are increased gradually in the extension direction of the guide grooves, the space, used for releasing pressure, between the inner side wall of the bucket tooth and a material base body is enlarged gradually in the process that the bucket tooth goes deeper into the mine tunnel, and the downward cutting efficiency of the bucket tooth is further improved.
Description
technical field [0001] The invention relates to an excavator, in particular to a method for removing the covering soil of a mine tunnel. Background technique [0002] At present, when construction machinery such as bulldozers and graders use rippers, due to the harsh and complicated working environment, the working load and impact load are relatively large, the racks and tooth tips of the rippers are subject to a large force, which is easy to cause damage and reduces the gear. The service life of the rod and the tooth tip will increase the cost and affect the benefit of the enterprise. Contents of the invention [0003] The purpose of the present invention is to provide a method for removing the overburden of a mine tunnel, which improves the range of use of the ripper and prolongs its service life at the same time. [0004] The object of the present invention is achieved through the following technical solutions: [0005] A method for clearing the overburden of a mine t...
