When I just learned to dig up the machine, I always envy the old driver brush the brush very well, but he can't reach the level of others. After several years of study and exercise, I have made great progress in all the technical books of the excavator, especially the brush slope technology, which is very good. This day a excavator driver in Ningxiang County, Hunan, is combined. Own
Experience, tell you how the excavator brushes the slope.
Brush slope: it is to smooth the sloping surface of the slope, such as road, large foundation pit and so on. It is simply to dig or leveling the slope. It is a technical work in the operation of the excavator.
First, the method of slope brush
There are two ways to brush the slope: parallel slope and right slope.
Parallel brush slope
Parallel brush slope is the parallel movement of the excavator and the slope, mainly using the side teeth and the side knife to cooperate with the rotary motion.
Alignment: the place without lines is mainly controlled by the judgement of the line of sight.
Slope control: there is no slope excavation in the middle slope line. The method of circular arc and diagonal line are used to control the generation of slope.
Right on the slope
The right pair of brush slope refers to the ninety degree of the upper body of the excavator and the slope, the whole bucket is excavated, and the moving excavator repeats the same action when the front is dug. This method is mainly used for the shaping of the sloping surface, which can be used in this method.

Operation control skills: the main use of side brush slope is the suitable operation of the lower pressure of the big arm and the small arm of the arm. The bucket is only used for the partial leveling of the slope. The main use of the action of the big arm and the small arm is to adjust the bucket only according to the slope.
Two, brush slope technique
Case 1
This is generally a loose soil fill. When the excavator has trimmed the fill slope above, the uneven slope should be leveled first. The technical difficulty is that the wide slope of a bucket is not enough. It needs the whole slope, that is, the whole is on a plane, and there are two techniques to repair the slope.
Skill 1
At this point, we can use some auxiliary methods, such as a line of lime or a straight line with a track. It will reduce a lot of visual errors by the line.
Skill 2
Take a pat on the back of the bucket, scrape it, and leave some smooth marks.
Case two
This is usually a slope excavated by earthwork or stone. It is harder to trim such a slope than the previous one. This slope is usually hard and the most difficult one is that the final effect of the slope must be a flat surface. When the slope is repaired, the driver faces the slope, so it is not possible to see the slope directly at one glance. It's on a flat surface, so it's also going to be used here.
To some small tricks:
Skill 1
First, make a flat table. If the excavator does not stop leveling, the repaired slope will become a smooth surface.
Skill 2
If a shovel can be best formed, if a shovel can not, then repair, here is a small technique, that is, one or two bucket teeth on the edge of the bucket can be placed on the already repaired slope, so that each time can be ensured.
Skill 3
Another problem that needs to be solved is that the trimmed slope is a whole plane. In the front of the first earthwork backfilling slope, we can assist with the method of lime line, but it does not work here, because the excavator is below, the driver can't see the line above. But we can use it. This method: the bottom side of the slope and the track of the excavator
With two parallel red lines and then maintaining the slope, the big arm and the track will be 90 degrees, so that it will not be wrong.
In order to grow quickly, the industry's new players need to practice diligently. It is good, good, straight and flat. On the machine, it is not allowed to look down the ground, not to repair the slope slowly, and to have experience in several times.
Brush up the slope is to achieve the heart! Eye! Machine to! Any skill is accomplished in practice, all of the drivers and friends practice a lot, and will soon be able to practice a good job.
