Problems solved by technology
When the hardness of the soil changes, the operator needs to adjust the posture of the blade according to the change of the soil hardness, otherwise it will easily lead to damage such as flameout, impact of machine structural parts, and reduced life of the hydraulic system
[0003] At present, the degree of self-adaptation of the motor grader for adjusting the load is not high, and the output power of the engine is adjusted to adapt to different working conditions, which can only be roughly divided into light-load and heavy-load working conditions, and cannot be used for specific working conditions. real-time response to the situation, the economy and work efficiency are not good

Embodiment
[0034] Please refer to figure 1 , figure 2 , image 3 with Figure 4, the embodiment of the present invention provides a grader 100 for leveling the ground. It can adjust the working state of the shovel 110 in real time according to the state of the vehicle and load resistance, so that the shovel 110 can always maintain an optimal cutting angle state, which is economical, practical and efficient. In this embodiment, due to the unevenness of the ground, the motor grader 100 will tilt up or down when leveling the ground. During this process, the inclination angle of the blade 110 relative to the ground is constantly changing. However, An excessively large inclination angle will increase the fuel consumption of the motor grader 100, and an excessively small inclination angle will result in too little cutting and low cutting efficiency. Therefore, it is necessary to use the blade control method of the motor grader to adjust the working state of the blade 110 so that the blade ...

The invention discloses a land leveler scraper knife control method and a land leveler, and relates to the technical field of land leveler control. According to the inclination angle of a front frame,the inclination angle of a swing frame machine frame and the hinged position of the front frame and the swing frame machine frame, the working state of the whole vehicle is judged; according to the rotating angle and the inclination angle of a scraper knife, the inclination angle of the swing frame machine frame and the displacement of a lifting cylinder, an extension oil cylinder and a swing frame oil cylinder, the working state of the scraper knife of the land leveler is judged; and the soil entering cutting angle and / or the soil entering depth of the scraper knife is controlled according to the working state of the whole vehicle and the working state of the scraper knife. Compared with the prior art, according to the land leveler scraper knife control method, the soil entering cuttingangle and / or the soil entering depth of the scraper knife can be adjusted in real time according to the state of the whole vehicle and the state of the scraper knife, so that the scraper knife can keep the optimal cutting angle state all the time, the economical efficiency is high, and the method is practical and efficient.
Description
technical field [0001] The invention relates to the technical field of grader control, in particular to a method for controlling a blade of a grader and the grader. Background technique [0002] The operating conditions of the motor grader are more complicated due to the influence of the soil quality, so when performing operations, the requirements for the operator's operating experience are relatively high. When the hardness of the soil changes, the operator needs to adjust the posture of the blade according to the change of the soil hardness, otherwise it is easy to cause damage such as flameout, impact of machine structural parts, and reduced life of the hydraulic system. [0003] At present, the degree of self-adaptation of the motor grader for adjusting the load is not high, and the output power of the engine is adjusted to adapt to different working conditions, which can only be roughly divided into light-load and heavy-load working conditions, and cannot be used for s...
