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 and 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 method for controlling a blade of a grader and a grader, and relates to the technical field of grader control. First, according to the inclination angle of the front frame, the inclination angle of the swing frame, and the hinge position of the front frame and the swing frame, determine the working state of the motor grader, and then according to the rotation angle and inclination angle of the blade, the swing frame machine The angle of inclination of the frame and the displacement of the lifting cylinder, the extension cylinder and the swing frame cylinder are used to determine the working state of the blade of the motor grader, and then according to the working state of the vehicle and the working state of the blade, control the cutting angle and / or entry of the blade into the soil depth of cut. Compared with the prior art, the blade control method of the motor grader provided by the present invention can adjust the cutting angle and / or cutting depth of the blade in real time according to the state of the vehicle and the state of the blade, so that the blade can always be kept at an optimal level. Cutting angle state, high economy, 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...
