Tibetan officers and soldiers use excavators to open bottle caps. What are the applications of excavators in life?

Excavators, also known as excavators, are earth-moving machines that use buckets to dig up materials above or below the bearing surface, load them into transport vehicles or unload them into the yard.

The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are working weight (mass), engine power and bucket capacity.

What are the uses of excavators?

1. Backhoe operation

Backhoe operations are generally carried out below the ground, mainly by digging.

(1) Dig with a stick and a bucket. When the bucket hydraulic cylinder and connecting rod, stick hydraulic cylinder and stick are all at 90? Angle, you can get the maximum digging force and digging efficiency.

(2) Try to keep the direction of bucket teeth consistent with the digging direction, and reduce the digging resistance and bucket teeth wear.

2. Front shovel operation

The front shovel operation is generally carried out above the ground, and the rotation mode of the bucket is opposite to that of the back shovel. Scrape the floor with the stick hydraulic cylinder. The digging force of the front shovel is less than that of the rear shovel.

3. Trenching operation

By configuring the bucket corresponding to the width of the ditch, the tracks on both sides are parallel to the sideline to be excavated, so that the ditch excavation operation can be carried out efficiently. When digging a wide ditch, dig both sides first and the middle part last.

4. Loading operation

When loading, the excavator should be moved to the back of the loading truck first, so as to avoid the bucket hitting the cab of the truck or other personnel when turning. It is easier to load at the back of the truck than beside it. It is more convenient to load from front to back and has a large loading capacity. ground grading

(1) Fill the ground first and move the bucket back and forth horizontally.

(2) When the excavator moves, don't level the ground with pressure or shovel.

(3) Smooth forward from the ground in front of the excavator, then gently pull the bucket and slowly lift the boom. When the bucket exceeds the vertical position, first lower the boom slightly, and then operate the machine to move the bucket horizontally.
