Multi-bucket hook-type bucket device for crushing of rock layer foundation

Abstract

The invention discloses a multi-bucket bucket device for rock foundation crushing, which includes a connecting plate, lugs with shaft holes are installed on both sides of the upper part of the connecting plate, and a trapezoidal bucket is welded between the two lugs. The reinforcing plate, two or more arc-shaped gear bars with bucket teeth are welded in the middle of the bottom of the connecting plate, and a reinforcing plate is welded between the square peripheral edge of the connecting plate and the outer wall of the gear bar. The distance between the upper ends of two adjacent tooth bars is 40-60cm. An alloy sheath is installed on the inner side of the curved surface of the tooth bar through a pin shaft, and a tooth sleeve is installed on the upper part of the bucket teeth. There are two protrusions on the top, and the protrusions extend along the direction from the bottom of the bucket teeth to the bottom of the tooth sleeve, and the thickness of the protrusions increases along the direction of their extension. The thickness of the protrusion increases along its extension direction, so that as the bucket tooth goes deeper, the space for releasing the extrusion force between the outer wall of the bucket tooth and the material matrix gradually increases, further improving the cutting efficiency of the bucket tooth.

Description

technical field [0001] The invention relates to an excavator, in particular to a multi-hook type bucket device for crushing rock layer foundations. 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 object of the present invention is to provide a multi-bucket bucket device for rock foundation crushing, which can improve the application range of the ripper and prolong its service life at the same time. [0004] The object of the present invention is achieved through the following technical solutions: [0005] A multi-bucket bucket devic...
