Embodiment Construction

[0020] Specific embodiments are described below with reference to the accompanying drawings.

[0021] like Figure 1 to Figure 3 As shown, the excavator in this embodiment is a crawler excavator, which includes a lower body 10 and an upper body, and the lower body includes an underframe, crawler beams 13 welded on both sides of the underframe, and a traveling motor and a guide rail are installed on the crawler beam. Wheels, tracks, etc.; the upper body includes a slewing platform 11 and work equipment, cab, power system (not shown in the figure) and the like mounted on the slewing platform. The slewing platform 11 is mounted on the chassis through a slewing bearing.

[0022] The working device includes a boom 15, a stick 16 and an attachment. The boom 15 is hinged with the slewing platform 11, the upper end of the stick 16 is hinged with the upper end of the boom 15, and the attachment is installed on the lower end of the stick. The attachment can be replaced according to th...

Abstract

The invention relates to an excavator, and aims to solve the problems that an existing excavator working device is tedious in operation and high in use cost when being converted between heavy weight and light weight. The excavator comprises a main machine and a working device installed on the main machine, the working device comprises a movable arm and a bucket rod which are of a box-type structure, and a first containing cavity used for containing fluid filler is formed in the movable arm and / or the bucket rod. The main machine is provided with a second containing cavity used for containing fluid filler, and the transfer device is connected with the first containing cavity and the second containing cavity and used for conveying and transferring the fluid filler between the first containing cavity and the second containing cavity. In the invention, when the working device of the excavator is switched between heavy weight and light weight, an external container for containing the fluid filler is not needed, and the fluid filler is carried along with the excavator, so that the operation is convenient, and the use cost is low.

Description

technical field [0001] The present invention relates to a construction machine, more particularly, to an excavator. Background technique [0002] As the king of construction machinery, excavators can achieve various functions such as excavation, loading and unloading, leveling, scraping, crushing, lifting, and traction by replacing attachments with corresponding functions, and are widely used. [0003] The working device of the excavator includes a boom, a stick and attachments mounted on the stick, and the boom and stick are usually box-shaped structures with a cavity. When the excavator performs different functional operations, the weight of the working device has different effects on the working efficiency. For example, when the attachment is a breaker, it is expected that the working device can be as heavy as possible, so as to suppress the reaction force of the breaker and avoid The beat of the breaker is transmitted to the whole machine, which makes the whole machine ...
