Abstract

The invention relates to an excavator. According to the excavator, the problems that an existing excavator is high in ground flattening operation difficulty and low in ground flattening efficiency are solved. The excavator comprises a main machine and a working device, and the working device comprises a movable arm, a bucket rod, a movable arm oil cylinder, a bucket rod oil cylinder, a connecting rod and rocker arms. The rear end of the movable arm is hinged to the main machine, the front end of the movable arm is hinged to the upper portion of the bucket rod, and the rear end of the bucket rod oil cylinder is hinged to the middle rear portion of the movable arm. The front end of the bucket rod oil cylinder is hinged to the upper portion of the bucket rod, the rocker arms and the movable arm are hinged to the lower portions of the rocker arms, and the front end of the connecting rod is hinged to the upper portion of the bucket rod, the rear end of the connecting rod is hinged to the upper ends of the rocker arms, and the lower ends of the rocker arms are hinged to the upper end of the movable arm oil cylinder. The lower end of the movable arm oil cylinder is hinged to the main machine. When the excavator conducts ground flattening operation, only a single handle is needed for operating the bucket rod, and thus a straight horizontal line is lined out by tooth tips of a scraper pan, and then a ground flattening operation circulation is completed. Compared with ground flattening action of the traditional excavator, ground flattening action of the excavator is simple in operation and high in ground flattening efficiency.

Description

technical field [0001] The present invention relates to a construction machine, and more particularly, to an excavator. Background technique [0002] As the king of construction machinery, excavators have various functions such as digging, loading and unloading, leveling, scraping, crushing, lifting, and traction, and are widely used in various constructions. Among them, leveling the ground is an operation that is often used. [0003] The working device of the excavator when leveling the ground is mainly composed of boom, stick and bucket. The rear end of the boom is hinged with the main engine, the front end is hinged with the stick, and the two ends of the boom cylinder are respectively hinged with the boom and the main engine. The expansion and contraction of the oil cylinder pushes the boom to rotate around its rear end to realize the up and down swing of the front end of the boom. The two ends of the stick cylinder are respectively hinged with the boom and the stick, ...
