What are the modes of operation of Grader? How are they operated?
(four) oblique homework;With the features of frame articulated or all wheel steering, the grader can work diagonally. In many job situations, diagonal operation is necessary to keep the wheels away from the pile and keep the machine more stable.
(three) outside scraping;The grader in operation, due to blade has certain rotation angle, or due to blade in the body and scraping the side slope, the machine by a lateral force, often forcing machine front wheel lateral that deviate from the direction of travel, wear of the tire, and the front wheel steering pin take a greater moment the front wheel steering (yaw) resistance increases, then the method can be used to avoid tilt wheel.
(two) sweep the soil straightThe direct displacement of the scraper is to rotate the scraper angle to 0 degrees, that is, the axis of the scraper is perpendicular to the direction of travel. At this time, the cutting width is the biggest, but it can only be operated with a small cut depth, which is mainly used to smooth the operation.
(1) scraping the soil side shift;In the course of cutting and moving soil, the soil flows along the side of the scraper, and the greater the turning angle is, the stronger the soil and soil removal capacity is. The scraper of lateral displacements should be careful not to make the wheels running on the data stack, should make the material from the wheels on both sides of the middle or through, can be used when necessary oblique method operation, that is expected to leave the wheel farther. Scraping and side shifting are usually mixed with the material. The material to be mixed will be cut off at one end of the scraper and removed from the other end of the scraper. At this point, it should be noted that the size of the rotary angle of the scraper should be of proper size and that the angle of the soil should be larger. But if the turning angle is too large, the material can not be fully rolled and mixed, which affects the mixing quality.When the scraper is moved sideways, it should also pay attention to adopting proper turning angle, and always keep a small amount of material before the scraper, but it is enough material, not only the resistance of running is small, but also the quality of the paving is guaranteed.Flat machine operations, in addition to the front or rear wheel steering machine along the route for homework, often need to manipulate the blade side to achieve trajectory of the shift to auxiliary scraper. When the curve or the boundary of the work surface is irregularly curved, the utility model can control the movement of the steering and the scraper at the same time, and flexibly and flexibly work along the tortuous boundary. When the side encountered obstacles, generally do not use the steering method to avoid, but the scraper side recovery, after the obstacle, then the scraper protruding. This method of operation is mainly used for moving soil, filling embankments, leveling sites, filling ditches and laying bulk materials.
