Problems solved by technology
[0004] However, at present, in the automatic leveling operation project of the grader, if there is an obstacle on the operation route, the blade of the grader cannot automatically adjust the height in advance or only adjust the height after the blade encounters an obstacle. Make a judgment in advance according to the working conditions, which may cause the motor grader to be too resistant to move forward, resulting in slippage on the spot, and the tire slipping or the blade hitting an obstacle will cause damage to the motor grader itself, which will affect the leveling while causing equipment loss job efficiency

Embodiment Construction
[0029] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.
[0030] Such as figure 1 As shown, an embodiment of the present invention provides a method for controlling a motor grader, the method comprising the following steps:
[0031] Step 110: Determine the current driving gear of the motor grader.
[0032] Specifically, during the running of the motor grader, it is necessary to keep the matching between the gear position and the speed. Motor graders operate at their best when the speed and gear correspond. If the speed does not match the gear position, high speed and low gear, low speed and high gear, etc., will ...

The invention discloses a land leveler control method and device and a land leveler. The land leveler control method comprises the steps that the current driving gear of the land leveler is determined; a comparison result of the current torque value of the land leveler and the maximum torque value corresponding to the current driving gear is determined; and when the comparison result meets the preset control condition, the height of a scraper knife is increased to a preset height value, wherein the land leveler automatically moves in a working area according to a preset route so as to carry out leveling operation, and the preset control condition represents that redundant piled soil appears in the preset route. According to the scheme provided by the invention, the leveling efficiency of the land leveler can be improved.
Description
technical field [0001] The present application relates to the technical field of engineering machinery, in particular to a control method and device for a grader and a grader. Background technique [0002] The grader is a common mechanical equipment used for leveling the land. At present, when the grader is used to level the land, it automatically moves in the working area through the preset operation route, and the blade on the grader is driven by the movement to level the ground in the working area. Land, to achieve automatic leveling operations. [0003] The working conditions of the motor grader are complicated. Sometimes, when the blade encounters a mound in the soil, the load may change suddenly and produce a large impact. As a result, the engine will often slow down or even stall, which will affect the operating efficiency. Motor grader manufacturers often increase the utilization of engine power to alleviate the impact of sudden load changes. However, the power of ...
