River channel dredging grab bucket device

Abstract

The invention provides a river channel dredging grab bucket device. The device comprises an adjusting mechanism, a supporting rod, bucket piece mechanisms and a pressing disc mechanism. The adjustingmechanism is a planar six-rod mechanism composed of a bucket rod, a grab bucket hydraulic cylinder, a rocker, a connecting rod and a connecting seat through hinging, wherein the grab bucket hydrauliccylinder is a driving part; the upper end of the supporting rod is fixed to the connecting seat of the adjusting mechanism; and the side wall of the supporting rod is provided with the bucket piece mechanisms uniformly distributed in the circumferential direction. Each bucket piece mechanism comprises a bucket piece hydraulic cylinder and a bucket piece. The lower end of the supporting rod is provided with the pressing disc mechanism, and the pressing disc mechanism comprises a pressure disc hydraulic cylinder fixedly connected with the lower end of the supporting rod, and a pressing disc fixedly connected with a piston rod of the pressure disc hydraulic cylinder. The side wall of each bucket piece is provided with a drainage groove. The river channel dredging grab bucket device takes theplace of a hydraulic excavator bucket mechanism to achieve grabbing, squeezing and removing of river channel sludge, and has the advantages of high convenience flexibility, high efficiency and low cost.

Description

technical field

[0001] The invention belongs to the technical field of grab engineering, and in particular relates to a grab device for dredging river channels. Background technique

[0002] The silt in the river needs to be cleaned regularly. If the silt in the river is too thick, it will cause a large number of bacteria to multiply, and it will greatly damage the purity of the water source and the navigation and flood discharge capabilities of the river itself. The common dredging method is to use a backhoe hydraulic excavator to dig , when dredging the river channel, generally by manipulating the working device of the excavator, the transfer and unloading actions are realized, and finally the silt is poured into the truck next to it. During the silt working process, when the bucket is fully loaded, it is necessary to keep the opening surface of the bucket parallel to the ground, and the bucket will remain in this state until the unloading work is performed, which reduces ...
