The grab bucket system of the embodiment 1 is provided with the balancing weight assembly 3 outside the grab bucket body 1, so that the excavating capacity of the bucket head assembly can be adjusted, the reverse flushing channel of slurry is not influenced, the lifting/lowering resistance of the slurry to the grab bucket body is effectively avoided, the fuel utilization rate is improved, and the high requirements of fuel economy and environmental protection are met.
As an alternative embodiment of the weight assembly.
Referring to fig. 1a, the balancing weight assembly 3 includes: the balancing weight groups 31 are distributed on the outer side of the grab bucket body 1; each set 31 includes at least two weights 311 arranged side by side. Since fig. 1a only shows a front view of the grapple system, the other two weight sets are blocked from being displayed.
The weight of the grab bucket body is adjusted through the balancing weights symmetrically distributed on the outer side of the grab bucket body 1 by the balancing weight assembly 3 in the embodiment, the reverse flushing channel of slurry is not affected, the number of the balancing weights 311 can be adjusted according to working conditions (such as geological conditions and slurry viscosity), the flexibility is high, meanwhile, the balancing weights are symmetrically distributed, and the verticality of the grab bucket body can be guaranteed, so that the grab bucket body is prevented from being inclined to affect the normal use of the grab bucket system.
Further, referring to fig. 1a and 2, the grapple system further comprises two slurry channels 4 provided in the middle of the grapple body 1, and four weight positions 5 symmetrically distributed on both sides of the slurry channels 4.
As an alternative embodiment of the weight.
