Description

Cutting device for excavators {Cutting Apparatus for Excavators}

The present invention relates to a cutting device for an excavator, and relates to a cutting device for an excavator that operates without hydraulic pressure and is easy to install.

Excavator is a construction machine that carries out the excavation work in the field of civil engineering, construction, construction site, loading work to transport the earth and sand, shredding work to dismantle the building, and stopping work to clean up the ground. It is composed of an upper swinging body and a work device mounted on the sieve and the traveling body to rotate 360 degrees.

Excavators are categorized into crawler type crawler excavators and tire type wheel excavators according to the driving method of the traveling body. Since crawler excavators are more stable and more productive than wheeled excavators, they are widely used at work sites ranging from 1 ton weight to over 100 tonnes of equipment.Wheeled excavators are tire-supported compared to crawler excavators. Due to its low stability during work, it is possible to travel on the road without moving trailers, and is mainly used for work sites that require frequent work and movement.

Excavators can also be used with appropriate work equipment, depending on the condition of the soil and rock, the type and purpose of the work. Buckets for general excavation and excavation of soil, hard ground, breakers for crushing rocks, etc., and crushers for dismantling and crushing buildings are working devices mainly used in excavators.

However, the prior art had the following problems.

The working device mounted on the excavator requires an additional motor for driving, and the device is complicated and difficult to install.
