Face shovel excavating and loading device capable of increasing pushing force and journey of bucket hydraulic cylinder

Abstract

The invention provides a face shovel excavating and loading device capable of increasing pushing force and journey of a bucket hydraulic cylinder. According to the face shovel excavating and loading device, the lower end of a moveable arm is hinged to a rack; the upper end of the moveable arm is hinged to one end of a bucket rod; the other end of the bucket rod is hinged to one part of a bucket; one ends of a pair of moveable arm hydraulic cylinders are hinged to one part of the moveable arm; the other ends of the pair of moveable arm hydraulic cylinders are hinged to the rack; the middle part of the bucket rod is hinged to one ends of a pair of bucket rod hydraulic cylinders; the other ends of the pair of bucket rod hydraulic cylinders are hinged to the rack; one ends of a pair of bucket hydraulic cylinders are hinged to one part of the bucket; the face shovel excavating and loading device is characterized in that a pair of bucket rod rockers are hinged to two sides of the bucket rod; the other two hinged points of the bucket rod rockers are hinged to other ends of the bucket hydraulic cylinders and one ends of a pair of moveable arm connecting rods; the other ends of the moveable arm connecting rods are hinged to other parts of the moveable arm. The face shovel excavating and loading device has the advantages that the energy consumption is low, the force transmission is reasonable, the working space is large, the control is easy, and the like.

Description

technical field

[0001] The invention relates to an excavator, in particular to a working device of the excavator. Background technique

[0002] The large-scale front shovel digging and loading device is the most commonly used working device for hydraulic excavators. It mainly takes blasted rocks, ores and vertical mine faces with a certain height as the main working objects. The working conditions are harsh, and the excavating working device is completed The main component of various functions of the excavator, so the excavator has very high requirements on the structure of the working device. However, domestic research on the structural innovation of hydraulic front shovel excavator working devices is less. State Intellectual Property Office of the People's Republic of China: Chinese patent (application number: CN201220011395.1) relates to a three-degree-of-freedom controllable mechanism excavator, including a boom lifting mechanism, a stick lifting mechanism, a bucket tur...
