[0033] Please refer to figure 1As shown, this embodiment provides an excavator grab, which is applied to an excavator. The excavator grab includes a grab main body (not shown in the figure), an interlocking assembly 110, a first lug 130, a second lug The plate 150 , the first pin shaft 170 and the second pin shaft 190 , the first lug plate 130 and the second lug plate 150 are perpendicular to each other and are respectively arranged on the main body of the grab bucket to enclose a locking space 140 . One end of the first pin shaft 170 passes through the first ear plate 130 and extends into the locking space 140 to be connected with the interlock assembly 110, and one end of the second pin shaft 190 passes through the second ear plate 150 and extends into the locking space 140 to be connected with the interlocking assembly 110. The interlock assembly 110 is connected, and the first pin shaft 170 and the second pin shaft 190 are interlocked through the interlock assembly 110. Th...

Abstract

The invention discloses an excavator grab bucket and an excavator, and relates to the technical field of excavator. The excavator grab bucket comprises an interlocking assembly, wherein the interlocking assembly comprises a first locking plate, a second locking plate and a locking block, one side of the first locking plate is connected with a first pin shaft of the excavator grab bucket, a clamping groove is formed in one side, away from the first pin shaft, of the first locking plate in a concave manner, one side of the second locking plate is connected with a second pin shaft of the excavator grab bucket, a fixing bulge block is arranged on the outer edge of one side of the second locking plate, the fixing bulge block extends into the clamping groove and is clamped by the clamping groove, and the locking block is accommodated in the clamping groove, props against the fixing bulge block and is used for limiting the fixing bulge blocks to slide along the clamping groove. The excavatorgrab bucket realizes rapid interlocking fixation of adjacent pin shafts, reduces the labor cost in the production process and substantially enhances the production efficiency.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to an excavator grab and an excavator. Background technique [0002] At present, the multiple pin shafts connected to multiple jaw plates on the excavator grab are respectively fixed on the corresponding multiple lug plates by adding welding plates and bolts to limit the movement of the pin shafts relative to the lug plates. . [0003] In the actual manufacturing process of the excavator grab, due to the limited space available between two adjacent lugs and the large number of pins, this kind of fixing method is used to fix multiple pins on their respective lugs. It takes a lot of labor cost on the board, and the efficiency is low. Contents of the invention [0004] The object of the present invention is to provide an excavator grab bucket, which can reduce labor costs in the production process and can improve production efficiency. [0005] Another object of the present inv...
