Several items in the field test of the scraper

Scraper field test 4 items. The scraper lateral movement operation is to keep the scraper at a certain rotation angle. During the cutting and soil moving process, the soil flows sideways along the scraper. The larger the rotation angle, the stronger the soil cutting and soil moving ability. The scraper direct movement operation is to set the scraper rotation angle to 0°, that is, the scraper axis is perpendicular to the driving direction. At this time, the cutting width is the largest, but it can only operate with a smaller cutting depth, and is mainly used for paving operations. When the grader is operating, because the scraper has a certain rotation angle, or because the scraper scrapes the side slope outside the machine body, the machine is subject to a lateral force. Utilizing the features of frame articulation or all-wheel steering, the grader can operate at an angle. In many working situations, it is necessary to adopt the diagonal working method to avoid the material pile and keep the machine more stable.
