Double-end bucket hook structure of large excavator

Abstract

The invention discloses a double-headed bucket hook structure for a large excavator, which includes a connecting plate, ear plates with shaft holes are installed on both sides of the upper part of the connecting plate, and a trapezoidal reinforcement plate is welded between the two ear plates. 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, two adjacent The distance between the upper ends of the 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 gear sleeve is installed on the upper part of the bucket teeth through a pin shaft. Two arc-shaped diversion grooves and protrusions are respectively arranged on the wall, and the protrusions and diversion grooves respectively extend along the direction from the bottom of the bucket teeth to the bottom of the tooth sleeve. The depth of the diversion groove increases along its extension direction, so that with the deepening of the bucket teeth, the space for releasing the extrusion force between the inner wall of the bucket teeth and the material matrix gradually increases, further improving the cutting efficiency of the bucket teeth.

Description

technical field [0001] The invention relates to an excavator, in particular to a double-headed bucket hook structure of a large excavator. 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 double-headed bucket hook structure for a large excavator, so as to improve the range of use 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 double-headed bucket hook structure fo...
