Face shovel and back shovel conversion device of excavator and excavator

Abstract

The invention relates to the technical field of excavators, in particular to a face shovel and back shovel conversion device of an excavator and the excavator comprising a conversion mechanism. The device comprises an excavator bucket, a small arm and the conversion mechanism arranged between the excavator bucket and the small arm; and a face shovel lug plate, a back shovel lug plate and a conversion lug plate are arranged on the excavator bucket, and the conversion lug plate is arranged between the face shovel lug plate and the back shovel lug plate. The conversion mechanism comprises a connecting rod detachably hinged to the face shovel lug plate or the back shovel lug plate, a rocker hinged to the small arm and a connecting ball shaft, one end of the connecting ball shaft is hinged to the conversion lug plate, the other end of the connecting ball shaft is in spherical hinge connection with the small arm, the connecting rod is hinged to the rocker, and a driving piece for driving the excavator bucket to work is arranged at the hinged position. According to the conversion mechanism, a face shovel and a back shovel can be rapidly converted without complete disassembly, the excavator bucket is connected with the small arm through the connecting ball shaft, the small arm fixes a steering ball sleeve, rotation of the excavator bucket is achieved through rotation of the connecting ball shaft, and the shovel type structure is effectively and rapidly changed.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to an excavator front shovel and backhoe conversion device and an excavator including the conversion device. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Excavators are mainly used for engineering construction, such as: roads, bridges, buildings, breeding ponds, underground engineering, emergency excavation, etc., which have the characteristics of strong strength, high efficiency, can complete projects that cannot be completed by manpower, and improve work efficiency. . [0004] The operation of the excavator includes front shovel operation and backhoe operation. The backhoe operation is generally carried out below the ground, mainly for excavation. The front shovel operation is generally carried out above the ground, and the stick hydraulic cylinde...
