Description
Technical Field
[0001] The utility model relates to the field of grab buckets, and particularly to a detachable double-lobe hydraulic grab bucket. Background Art
[0002] A grab bucket is a special tool for a heavy machine to grab dry bulk goods. It consists of two or more openable and closable bucket-shaped jaw plates that together form a material-containing space. When loading, the jaw plates are closed in the material pile, and the material is grabbed into the material-containing space. When unloading, the jaw plates are opened in a suspended state on the material pile, and the material falls on the material pile. The bucket teeth of the grab bucket need to be replaced and disassembled during long-term use. For example, a four-cylinder-driven clam-type electro-hydraulic double-lobe grab bucket provided in Patent No. CN 211846881 U includes a main body. The main body includes a connecting piece, a driving device, and a grab bucket body from top to bottom. The driving device and the grab bucket body are connected by a connecting rod assembly. The grab bucket body is a left-right double-lobe structure. The connecting piece includes a fixer fixedly installed at the upper end of the driving device. A pin lock is installed at the upper end of the fixer through a chain. The driving device includes symmetrically arranged hydraulic cylinder assemblies. The hydraulic cylinder assemblies are connected to the connecting rod assembly and push the grab bucket body to act through the connecting rod.
