Brief description of the external soil scraping method of the grader

[DIG-DOG]

The scraper operation surface cannot be constructed by the three scraping operation methods of scraper direct movement operation method, scraper side movement operation method, and blade angle shovel side movement method at the construction site outside the machine. The scraper operation method outside the machine must be used. Today, the manufacturer of accessories will briefly introduce the scraper operation method outside the grader.
The scraper operation outside the machine is mainly used for the correction of the slope of the embankment and cutting, as well as the excavation of the side ditch and other operations.
Before the operation, the scraper should be tilted outside the machine, and then the turntable should be turned so that the upper end of the scraper faces forward, and then the scraper is lowered along the slope. The force condition of the scraper outside the machine is poor, and the first gear driving operation should be used to improve traction. During the operation, the soil scraped and stripped by the scraper will be unloaded along the scraper surface between the left and right wheels of the grader, and finally the unloaded soil embankment will be removed. When brushing the side slope of the ditch, the scraper plane angle can be selected to be smaller due to the small amount of unloading; when brushing the roadbed or road cutting slope, the scraper plane angle should be larger due to the large amount of unloading and the resistance to unloading.
Correctly selecting the rotation plane angle and shoveling angle of the scraper is an important factor in improving the efficiency of the grader. Usually, a larger plane angle can increase the shoveling traction per unit working length of the scraper. In the shoveling operation, a larger shoveling angle should be selected to improve the flatness and mixing effect.
The basic construction method of the grader scraper can complete various operations. Before construction, the construction procedure should be formulated and one or more construction methods should be used for construction.
The main construction operation forms of the grader include road repair, road trench excavation and road mixing and roadbed paving materials, etc. The construction procedures of different operation forms are also different.
The above is the external scraping operation method of the grader introduced by the accessories editor. I hope the above content can help you.
