Description

Digging machine

Technical Field

The utility model belongs to the field of engineering instruments, and particularly relates to an excavator capable of performing wet operation.

Background

An excavator, also known as an excavating machine (excavating shovel), is an earth moving machine that excavates material above or below a bearing surface with a bucket and loads the material into a transport vehicle or unloads the material to a stockyard.

The materials excavated by the excavator mainly comprise soil, coal, silt, soil subjected to pre-loosening and rocks. The development of excavators is relatively fast, and the excavator becomes one of the most important engineering machines in engineering construction.

Originally the excavators were manual, for over one hundred thirty years since invention and 2013, during which a gradual progression from steam driven bucket rotary excavators to electrically driven and combustion engine driven rotary excavators, fully automatic hydraulic excavators applying mechatronic technology was experienced. The first hydraulic excavator was invented successfully by the polka works, france. Due to the application of hydraulic technology, in the 20 th century, 40's, there were suspended excavators equipped with hydraulic backhoes on tractors. In 1951, the first full-hydraulic backhoe excavator was introduced by a Poclain (pocelan) factory in france, thereby creating a new space in the technical development field of the excavator, and a towed full-swing hydraulic excavator and a crawler type full-hydraulic excavator were successively developed in the early and middle stages of the 50 th century. The hydraulic excavator manufactured in the initial trial is a hydraulic technology adopting airplanes and machine tools, hydraulic elements suitable for various working conditions of the excavator are lacked, the manufacturing quality is not stable enough, and the matching parts are not complete. Since the 20 th century and the 60 th year, the hydraulic excavator enters the stage of popularization and vigorous development, excavator manufacturers and varieties in various countries are increased rapidly, and the yield is increased dramatically. In 1968-1970, the yield of the hydraulic excavator accounts for 83% of the total yield of the excavator and is close to 100%.

First generation excavators: the advent of electric motors and internal combustion engines has provided excavators with advanced and appropriate electric devices, and various excavator products have been produced in succession. In 1899, the first electric excavator appeared. After the first world war, diesel engines were also used in excavators, and such diesel engine (or electric motor) driven mechanical excavators were the first generation excavators.

The second generation excavator: with the wide use of hydraulic technology, the excavator has a more scientifically applicable transmission device, and hydraulic transmission replaces mechanical transmission to be a great leap in the excavator technology. The first hydraulic excavator in germany was born in 1950. The mechanical transmission hydraulics are second generation excavators.

A third-generation excavator: the wide application of electronic technology, especially computer technology, makes the excavator have an automatic control system, and also makes the excavator develop towards high performance, automation and intellectualization. The germination of mechatronics occurred around 1965, while the adoption of mechatronics technology on mass-produced hydraulic excavators was around 1985, when the main objective was to save energy. Excavator electronization is the hallmark of third generation excavators.
